Will double glazing save me money on energy bills?

Yes. Windows account for up to 15% of heat lost from a property and doors can contribute further. Upgrading to A-rated double glazing significantly reduces this heat loss, meaning your heating system operates more efficiently and your monthly bills fall. Combined with other insulation improvements, the savings compound further.

How effective is double glazing at blocking external noise?

High-quality double glazing can reduce sound pollution by 20 to 65% compared to single glazing. The two panes and the insulating gas-filled gap between them absorb and dampen sound vibrations. Triple glazing provides even greater acoustic performance.

Do I need planning permission to install double glazing in Billericay?

In most cases, like-for-like double glazing replacement falls under permitted development and does not require planning permission. Exceptions apply if your property is listed, within a conservation area, or is a flat or maisonette. Billericay falls within Basildon Borough Council jurisdiction — check with them if any of these apply before commencing work.

Can I install double glazing in a flat in Billericay?

Yes. As a leaseholder, you will typically need consent from your freeholder or management company before replacing windows, to maintain the building's exterior appearance. Listed building consent may also be required if the building is listed. Contact your freeholder and, if necessary, Basildon Borough Council before proceeding.

Are there government grants for double glazing in Billericay?

Two national schemes are currently available. The Warm Homes: Local Grant supports low-income households earning under £36,000 per year or those receiving benefits, with homes rated EPC D-G, towards double glazing and other energy efficiency upgrades — distributed via local councils. The ECO4 Scheme requires energy companies to fund qualifying energy efficiency improvements including double glazing for low-income and vulnerable households. Contact Basildon Borough Council or your energy supplier for eligibility details.

Will I need a FENSA certificate when selling my home in Billericay?

Yes. A FENSA certificate or equivalent Building Regulations certification is required for replacement windows and doors installed since April 2002. Solicitors and buyers will request this during conveyancing, and not having it can delay or complicate a sale. All Homeglaze installations are FENSA certified.

Double Glazing Billericay

Q: What is double glazing?

Double glazing is a window unit with two panes of glass separated by a sealed gap filled with air or an insulating gas such as Argon. This creates an insulated glass unit that reduces heat loss, prevents cold air ingress, reduces noise and improves security compared to single glazing.

Q: Will new double glazing increase my property value in Billericay?

Double glazing consistently increases property value in Billericay and across Essex. It improves energy efficiency ratings, kerb appeal and security — all of which buyers factor into offers. Installing full sets of windows and doors rather than individual units delivers the greatest uplift in value and marketability.

Q: What is an A-rated window?

Window energy ratings run from G (least efficient) to A++ (most efficient). An A-rated window delivers excellent thermal performance, significantly reducing heat loss and lowering heating bills. Our windows are A-rated as standard, meaning you receive the best available energy performance from the outset.

Q: What is U-value and what does it tell me about my windows?

U-value measures the rate at which heat transfers through a window. A lower U-value indicates less heat loss and better insulation. The minimum required for new windows under Building Regulations is 1.8 W/m2K. Our windows achieve significantly lower values than this minimum.

Q: When is it time to replace my windows?

Key signs include draughts when the window is closed, condensation between the glass panes indicating seal failure, difficulty operating handles or locks, visible structural damage to the frame, or noticeably higher energy bills. uPVC and aluminium windows typically last 20 to 35 years. We will always assess whether a repair is viable before recommending replacement.

Q: Should I replace all my windows at once?

Replacing all windows at once is recommended where budget allows. You pay installation labour only once, benefit immediately from improved energy efficiency and security across the whole property, and achieve a consistent aesthetic. It also makes the property more attractive to buyers when you come to sell.

Q: Can double-glazed windows be installed in a conservation area in Billericay?

Yes, but planning permission or listed building consent is typically required as double glazing can be considered a significant alteration affecting the historical character of the area. Local authorities generally prefer like-for-like replacements. Slim-profile glazing and heritage-style units that maintain the building's aesthetic are often the approved route. Contact Basildon Borough Council for specific guidance on your property.

Increasing Your Overall Property Value With Our Range

We supply and install double and triple-glazing products of the highest quality. They are designed with energy efficiency and security in mind to truly enhance your home. Because you are saving money on energy bills, increasing security and making your property look fantastic, installing our products is well known to increase the overall value of your property.

Installing a combination of products in one go is a great way to increase the value of your property and make your property more enticing to potential buyers when it’s time to sell. This is because your home will look fantastic, and a new buyer won’t have to worry about installing new windows, doors or other items in their home.

You can also combine your investment in double-glazing with other insulation in your property. This further saves you money on your energy bills and makes your property more energy efficient. Up to 35% of heat in the winter is lost from windows and doors, depending on their insulation, and another 35% can be lost from poor insulation in the walls. So, your heating could be running at 70% less efficiency than it could be, meaning it takes longer to heat the property, and the property will cool down faster. The insulation also helps in the summer, keeping your home cool and the heat out. Get in touch with our team to arrange for your free quote.

Double Glazing For Your Windows

Double-glazed windows are highly energy efficient and noise-reducing, providing you with comfort at home. This provides a more peaceful environment in your home and a more comfortable environment, which saves you money on your energy bills each year. The dual-pane design with a gas or air layer between the glass significantly dampens external sounds.

Windows and doors are the most popular double-glazing and triple-glazing products. Every home has them, and you can massively benefit from upgrading them. Your front door and all of your windows are exposed to the outdoors, which sees environmental damage over time, and cold can get in and heat can get out if they aren’t as efficient as they could be. Windows account for up to 15% of heat lost if they aren’t efficient, so you are effectively making your heating up to 15% more efficient in the winter when you invest in upgraded glazing for your windows. Security is also a big concern for homeowners; all of our windows are designed with security in mind and are fitted with state-of-the-art locking mechanisms for your peace of mind.

Replacement Glazing and Repairs

Over time, due to natural wear and tear, glazing in windows and doors can deteriorate. There are some issues, such as extensive damage to the window seals, that will mean that the window will need to be replaced. Several different issues can be repaired, and we will always try to repair an issue before recommending that a replacement is needed. Issues that you can experience are fogging in the glass or condensation, cracks or loss of thermal effeciency. The glazing could also completely break due to an accident or vandalism.

Our cost-effective solutions will repair your windows and other glazing to improve thermal performance, reduce noise and improve overall efficiency across the board. Whether it’s a single window or you need to improve a number of different windows or glazing, we have you covered. Get in touch with our team to arrange for your free repair quotation.

Further Ways to Improve Your Property and Its Value

Bifold doors and patio doors are wonderful additions to your property and make an amazing link to the outdoors. They add a lot of charm to the property and are also known to increase property value. Aluminium has become a highly popular choice for modern designs, with UPVC also being a great choice with colour matching to match other materials.

Conservatories have evolved from being just a room in your home that can be used for entertainment. They are now fully functional extensions that enhance your property, which adds another room. You can choose to move a current room into the conservatory and then change that room to a new room, such as an extra bedroom. Our conservatories are highly energy efficient and are constructed with the highest quality materials. If you are unhappy with your current conservatory because it isn’t insulated and is too hot in the summer and too cold in the winter, we offer replacement conservatory roofs to try to fix the issue before having to proceed with a full replacement. In some cases, the conservatory will have to be replaced. Your conservatory will add value to your property, around 5% to 15% depending on the size of the conservatory and the materials used.

Frequently Asked Questions

What Is Double Glazing?

Double glazing is a window with two panes of glass, separated by a sealed gap filled with either air or an insulating gas such as argon. This creates an insulated glass unit, which can reduce heat loss and prevent cold air from entering your home.

Does Double Glazing Make A Difference?

Yes, double glazing makes a significant difference in terms of improving energy efficiency, reducing noise and making your home comfier and more secure.

Are Double Glazed Windows Difficult To Break Into?

Yes, double-glazed windows are difficult to break into. The two panes of glass create a much stronger barrier. A forced entry through the two panes will require significantly more time and effort. The inert gas within the two panels acts as a shock absorber, further enhancing the window’s strength and deterring burglars.

Will Double Glazing Save Me Money On My Energy Bills?

Yes, double glazing is an excellent way to save money on your energy bills, as it prevents heat loss. When upgrading from single glazing to A-rated double glazing, you can save money, depending on your property type and current insulation levels.

Single-glazed windows are responsible for a significant level of heat loss. Double-glazed windows have a sealed, insulated glass unit, which reduces this heat loss, making your home significantly more energy-efficient. By keeping the heat in, you will use less energy heating your home, therefore, lowering your monthly energy bills.

What Makes A Sealed Glass Unit Thermally Efficient?

A sealed glass unit is thermally efficient because of the insulated gas-filled pocket between the two panes of glass. This pocket slows down heat transfer, making it difficult for heat to escape in winter and enter in summer, therefore making your home more thermally efficient.

How Effective Is Double Glazing At Blocking Out External Noises?

Double glazing is highly efficient at reducing external noise. In fact, high-quality installations can reduce sound pollution by 20-65%. This is because the unit has two panes of glass and the insulating gap between them, which absorbs and dampens sound vibrations.

Will Fitting New Windows Add Value To My Home?

Yes, installing new windows in your home is a great way to improve the overall kerb appeal of the property, as well as energy efficiency, security, and marketability. These all add value to your home, as buyers will be willing to pay more for a home that requires less renovation and is more energy-efficient.

What Is An ‘A’ Rated Window?

A-rated windows are some of the most energy-efficient windows available. Windows are rated on their energy efficiency using a scale, from G, the least efficient, to A++, the most efficient. Having a highly efficient window will further reduce the amount of heat lost from your home, lower your heating bills, reduce your carbon footprint, and give your home improved overall temperature control and comfort.

What Is U-Value, And What Does It Tell Me About My Windows?

U-value is a measure of thermal transmittance. Therefore, it tells you the rate at which heat transfers through your windows, measuring how effective your windows are at insulating your home. A lower U-value is better. It signifies less heat loss, better insulation and higher energy efficiency. A higher U-value indicates a poor insulator, allowing more heat to escape in the winter.

How Does Double Glazing Make My Home More Energy Efficient?

Double glazing will make your home more energy efficient due to the sealed layer of air or inert gas between the two panes of glass. This trapped layer significantly reduces heat loss in winter and heat gain in summer, meaning that your heating system doesn’t have to work as hard, lowering your energy consumption.

Will New Double Glazing Increase My Property Value in Billericay?

Yes, double glazing typically increases property value, as it boosts energy efficiency, improves kerb appeal, increases security and makes a home more attractive to buyers. Double glazing will be a worthwhile investment, especially if you are replacing less-efficient single glazing or older units.

When Is It Time To Replace My Windows?

Windows are built to last, with UPVC and aluminium windows having long lifespans. However, it’s important to know the signs that your windows are showing damage and need to be repaired or replaced. If there are drafts around your window even when they are sealed, then this will be causing your home to be less energy efficient, which costs you money on energy bills each year in the winter. This can be a sign that the seals on the window have failed, and another indication of this is condensation in the glass.

If the opening and locking mechanisms of your window are broken, this can be a security risk, and you may need to repair or replace the handles on your window or windows. We will always try to repair your windows, but these issues may require replacements for the handles. If there is structural damage, you may have to replace the entire window.

When Is It Time To Replace My Front Door?

Windows, doors and other parts of your home that can be upgraded with double-glazing products account for a large amount of heat loss in the winter. Windows and doors can account for up to 30% of all heat loss, so you can expect to save a significant amount on your energy bills. Combining this with other forms of insulation, you can massively insulate your home with which will give you a healthy boost to overall property value.

Extensions are supposed to be fully living spaces; however, older styles of extensions (particularly conservatories and orangeries) were constructed with low-quality materials that wouldn’t pass building regulations today. This results in extensions that are too hot in the summer and too cold in the winter, so you can’t use this room all year round. This also makes you spend more on energy bills, as the extension will waste heat in the winter, and it will be a lot harder to heat your home. In most cases, we can replace your conservatory roof, which will prevent you from having to replace the entire extension. Unfortunately, in some cases where the conservatory is damaged by condensation or leaking on the roof, the entire conservatory will need to be replaced. We can advise you on this and provide you with the best solution to upgrade your conservatory.

How Long Do Double Glazed Windows Last?

Double-glazed windows will last between 20 and 35 years. This will vary depending on the materials the frames are made from and whether the windows are maintained; however, with proper care, they will last for many years to come.

Should I Replace All My Windows At Once?

If you can afford it, it is recommended that you replace all your windows at once. This will save you time, stress and paperwork, and means that you don’t have to pay twice for the installation. Also, you’ll instantly feel the benefits of your new double glazing by replacing all your windows at once.

How Long Does An Installation Typically Take?

The installation time for your new windows will depend on the number, size and types of windows we are installing. Our team will advise you on the length of your window replacement to allow you to prepare beforehand.

Will Lots Of Mess Be Created From Having New Double Glazing Installed?

Our team will install your double glazing with as little mess and disruption as possible. We will leave your home exactly as we found it, and treat it as if it were our own.

Do I Need Planning Permission To Install Double Glazing?

You will not need planning permission to install double-glazed windows. This is because they fall under ‘permitted development’. However, this is only the case if the new windows are a similar size and appearance to the old ones.

Planning permission will be required if your property is in a conservation area, is a listed building, or is a flat or maisonette.

Can Double Glazed Windows Be Installed In A Conservation Area?

Yes, double-glazed windows can be installed in a conservation area; however, you’ll often require either planning permission or listed building consent, as they will be viewed as a significant alteration which can affect the historical character of the property.

Local authorities often prefer ‘like-for-like’ repairs, so installing windows that maintain the building’s aesthetic is recommended.

Can Period Properties Have Double Glazing?

Choosing to upgrade to double-glazing from older single-glazed windows can have a range of benefits. Mainly offering improved thermal comfort, this can help you retain heat in your home and reduce your energy consumption – a benefit for older properties that can often be harder to keep heated. Double glazing will also help increase your security, thanks to the tougher construction of the frames and glazing, which can reduce your household insurance costs.

This, however, does require careful planning. Often, planning permission and listed building consent, especially for listed buildings, require you to maintain the historical character of the property when installing energy efficiency upgrades. You can often find slim-profile glazing and heritage-style units that will mimic a range of factors, including timber-effect and original sash and casement styles.

Can I Install Double Glazed Windows In A Flat?

Yes, double glazing can be installed in a flat. You will usually be required to obtain planning permission and consent from the freeholder or management, especially if the windows you plan to install differ from the existing ones in style, size or material, to maintain the building’s exterior appearance.

Generally, you won’t need permission for windows that are identical or a like-for-like replacement. However, if you are a leaseholder, you will still need to confirm that this replacement gets signed off by the landlord, freeholder or management team.

If you live in a listed building, you will likely need listed building consent. Therefore, you must contact your local planning authority for further advice on design and materials. After all, work on a listed building can affect the historic character of the property, and doing so without consent is a criminal offence.

Do You Offer Payment Plans/Finance On Windows?

Yes, we do. Here at Homeglaze, we understand that installing new windows in your home can be a significant financial undertaking. We offer several financial plans to help make double glazing a more financially viable option.

We offer an interest-bearing balance-reducing loan, allowing you to spread the cost of your double-glazing installation over 24, 48, 60 or 120 months.

Our second option is buy now, pay later, allowing you to defer payment for up to 9 months from the installation date. No monthly payments are required with this option, and you can pay the amount at a frequency that suits you.

Why Is There Condensation Between My Double Glazing?

Condensation appears between the two panes of double glazing when the sealed unit fails, allowing moisture and air to enter it. This indicates that there is a problem with the window, and it is time to replace it, as the energy efficiency of the window has been compromised.

Are You FENSA Registered?

FENSA is a government-authorised UK scheme which certifies that an installer meets energy efficiency standards and building regulations. This scheme protects homeowners, accrediting installers, guaranteeing that their work is registered with the local council and that warranties are issued to provide proof of compliance when the property is sold in the future.

Here at Homeglaze, we’re proudly FENSA registered.

Can You Recycle Old Double-Glazed Windows?

Double-glazed windows are highly recyclable. The uPVC frames and the glass can be separated and reused. Typically, this occurs in a ‘closed-loop’ system, where they are recycled into new windows or other products, saving them from landfill, where uPVC can take a very long time to break down.

Can I Customise The Colour Of My New Windows?

Yes, you can customise the colour of your new windows. You’ll find that there is a wide variety of colours and finishes to choose from, so you can choose the one that best suits your aesthetic and personality, to boost your kerb appeal even further.

Can I Choose The Handles and Hardware For My Windows?

Modern double-glazed windows are available with a wide variety of handles and hardware.

What Should I Do If My Double Glazing Has ‘Misted’?

When you notice mist or fog between the two panes of glass, it means that the double-glazing seal has failed. Often this is referred to as when the double glazing ‘blows’. When the airtight seal between the glass panes fails, moisture and air are let in, thereby creating condensation, mist, or cloudiness between the panes. This can not only reduce clarity, but also insulation, leading to heat loss, higher energy bills, drafts and also potential damp and mould issues.

Why Is It Important To Choose A Reputable Double Glazing Installer?

A reputable double-glazing installer will ensure that you receive quality products that are installed professionally, whilst also staying compliant with building regulations and offering reliable after-sales service.

After all, you want the peace of mind that your windows will be installed properly and will last for many years, right? Reputable companies will consistently work with the customer’s best interests in mind, with the knowledge to adhere to and follow local building regulations and safety standards. Doing your research will minimise your risks of running into rogue traders who provide poor-quality workmanship.

Are There Any Government Grants For Windows in Billericay?

The main government scheme currently available that includes windows is the Warm Homes: Local Grant. This scheme helps low-income households, earning under £36,000 per year, or those on benefits, with homes rated EPC D-G, with funds towards double glazing and other energy efficiency upgrades. This is distributed via local councils.

The ECO4 Scheme is also designed to help low-income households and vulnerable individuals gain access to double glazing and other energy efficiency improvements. Through this scheme, energy companies are required to support qualifying customers in installing energy-efficient upgrades that help them save energy and reduce bills.

Will I Need A FENSA Certificate If I Sell My House?

Yes, you’ll likely need a FENSA Certificate, or an equivalent Building Regs certification, for replacement windows and doors. This has been in place since April 2022 to prove compliance with UK Building Regulations. Having this certificate ensures a smooth sale and avoids buyer issues, fines, or delays. Whilst it’s not a strict legal requirement to list the house, not having it can create problems and slow things down later on.

How Can I Tell If I Have Single Glazing, Double Glazing or Triple Glazing?

You can tell whether you have single glazing, double glazing or triple glazing by looking at the number of glass panes and the space between them.

A torch can help you to see the reflections of the glazing and the spacer bars on the edge of the window. Triple glazing is significantly thicker than single and double glazing.

Two panes of glass separated by a small space system means that you have a double-glazed window. If you see a single pane of glass and no spacing system, you have single-glazed windows.
