Does Double Glazing Add Value To A House?

Double glazing products are well known to increase property value, but just how much should you expect to add in value for each product?

Please take a look at the average values that you should expect when installing our different double glazing products.

See below for a rough value of your home if you were to invest in new double glazing:

EPC Improvement	Avg. Uplift to Asking Price	Value Impact on £300,000 Home	Primary Source(s)
D → C	~3-4%	~£9,000–£12,000	Rightmove; Knight Frank
E → C	~8%	~£24,000	Rightmove
F → C	~15-20%	~£45,000-£60,000	Rightmove; Knight Frank
A / B vs. D	~1.7-2.8%	~£5,100-£8,400	Nationwide HPI
Whole-Home Double Glazing (Single → Double)	Up to 10%	Up to ~£30,000	Industry Average

These are rough averages, and the value you can expect to achieve depends on your property’s location and size. For accurate estimates, speak to a home valuation expert or estate agent, or look at similarly priced properties in the area with these upgrades.

What are the Key Takeaways?

Achieving a Band C rating is the main target for most homeowners and landlords. This is the largest return, especially when you consider the work required doesn’t take a huge amount of time to reach Band C.
Pushing a property from C to B or A has lower percentage increases compared to a low-efficiency property.
The products that you choose to install don’t have to be expensive. We can work with you to suggest products that suit your budget and improve your efficiency ratings.

Why Does Increasing Efficiency Increase Overall Property Value?

You see much larger percentage increases in percentages in property value from going from very low to higher ratings because the property will be wasting money each year on heating in the winter. At the higher bands, the property is also likely to be too hot in the summer and too cold in the winter.

You can also have a range of issues with inefficient houses. Such as condensation, mould build-up, and moisture damage to walls.

Which Parts of Your Home Are the Top Areas to Review for Efficiency?

Hot air rises and also tries to escape to the outside, so these are the areas that need to be reviewed for efficiency, and products need to be selected in these areas specifically to increase efficiency.

Loft and Roofspace – Heat is rising, so you can expect around 20% of all heat loss to be from these areas. Consider checking for gaps, draughts, uninsulated water tanks or older insulation that has degraded.

External Walls – Heat is absorbed by the walls, so it’s going to take longer to heat the property. Expect around 35% on average to be lost by inefficient walls, and these will need insulation.

Windows & External Doors – Accounts for 10 to 15% of heat loss on average. This can be even more for old or inefficient products. Upgrading to double or triple glazing is the best way to improve efficiency here.

Your Heating System – If it’s old, it may be running at low efficiency. New systems can run at much higher percentages & heat the property faster.

The Floor – Ground floors also absorb heat and can be inefficient, accounting for an average of 15% heat loss.

Which Double Glazing Products Are Designed for Increasing Energy Efficiency?

Windows and doors are prime areas for heat loss. As there is 10 to 15% or more heat loss from inefficient windows and doors, these are a great area to review in terms of increasing your overall property value.

Upgrading your old windows and doors and then achieving a better EPC Band is a great way to increase the value of your property and save you money on your energy bills.

There are other areas of the property that can see increases too. Upgrading the glazing on extensions, if they need upgrades, or upgrading a conservatory roof for your conservatory can increase property value further.

What About Listed Buildings?

Listed buildings have problems because they are protected, but they typically have single-glazing, so they aren’t very efficient at all. Because of this, many councils and authorities have become more and more open to the idea of glazing upgrades, as long as they are in line with listed consent.

We have a very detailed article on double and triple-glazing products for listed buildings, which you can find here if you are looking for more information.

Can Double Glazing Really Help Me Save On My Heating Bills?

Yes! Double glazing can help lower your heating bills, particularly if you are upgrading from single glazing.

The main benefit of double glazing is that it can help keep rooms warm by preventing heat from escaping. That means your heating won’t need to be on as much or at as high a temperature, reducing your heating bill.

Double glazing lasts around 25-30 years, so you should save a significant amount of money over the years by choosing energy-efficient windows.
