Fire Escape Windows: Which Rooms Legally Needs One?

When installing new windows, one thing that often takes homeowners off guard is the need for fire escape windows.

This is often overlooked on older properties and loft conversions; however, having a fire escape window, also known as an egress window, in the right place is critical to provide occupants with a safe escape route if the main exit is blocked.

Below we’ll look at the current building regulations, what they require and which rooms need fire escape windows. Here at Homeglaze, we’re experts in providing double glazing in Essex and will have you covered when it comes to ensuring your new windows are compliant.

What Is A Fire Escape Window?

A fire escape window lets occupants climb out safely should a fire block the normal exit from a building. They are often referred to as egress windows in more technical terms.

After all, if a fire starts on the ground floor and blocks the hallway or staircase, people on the upper floors need an escape route.

With a fire escape window, occupants can climb through the window onto a flat roof, a balcony or down to ground level where firefighters can reach them.

Not every window in the property needs to be a fire escape window. There are specific regulations covering which rooms need these windows and what the window opening must do when fully open.

Where Are Fire Escape Windows Required In a Property?

Your windows’ fitment will ensure that all of the security features are working properly.

Ground Floor Rooms: A habitable room that does not open directly into a hallway leading to an outside exit door, such as living rooms, bedrooms or studies, needs fire escape windows. Kitchens, utility rooms and bathrooms are excluded from this.

Upper Floors: Habitable rooms on the first floors or upper levels under 4.5 metres high need escape windows unless the room opens directly onto a protected stairway.

Loft Conversions: Virtually all habitable rooms in a loft conversion require fire escape windows because they sit above the standard protected escape route. Building Control will expect every habitable room in the loft conversion to have at least one window that meets full fire escape requirements.

Extensions: If your extension will change the layout of the ground floor, meaning that an existing first floor room no longer has direct access to the staircase, it may now require a fire escape window where it didn’t previously exist. A single-storey extension won’t usually trigger escape window requirements; however, it’s always worth checking with your local building control team before any work starts.

New Builds All new builds must comply with the fire escape window requirements from the outset. Your builder or architect will factor this into your design. Your local planning department and Building Control will apply these rules depending on your home’s layout, usage, or historical status.

What Are The Fire Escape Window Size Requirements and Opening Dimensions?

To be classed as a compliant escape window in England and Wales, the window must meet all of the following criteria:

Minimum Opening Dimensions

Unobstructed opening area: 0.33 m2
Minimum height: 450mm
Minimum width: 450mm

These are minimum requirements, so the actual opening may be larger to meet the size criteria simultaneously.

Opening Style

The window must be side-hinged for easy passage
It must be fully openable without use of a key or tool
The opening must be bottom-hung or side-hung, not top-hung.

Height From The Floor

The bottom of the window opening must be no more than 1100mm above the floor level, as measured internally
This ensures that it is accessible for children, elderly, and disabled occupants in an emergency.

External Access

You also need to consider the area immediately outside the escape window:
It should open onto a safe place, typically a flat roof or external path, rather than an enclosed courtyard unless the property has had a proper risk assessment
Nothing must be blocking access
If the window opens on ground level, it should be within easy reach of the ground or a suitable platform like a flat roof.

What Are A Landlord’s Responsibilities?

Under the Housing Act 2004 and the Housing Health and Safety Rating System (HHSRS), landlords must ensure that their tenants have safe and effective means of escape that are functional, unobstructed, and maintained in a safe, operable condition for evacuation.

Core Responsibilities

Core responsibilities of a landlord, when it comes to fire escape windows, include:

Ensuring windows designated as emergency escape routes open easily and are not painted shut, warped, or structurally jammed
Ensuring that the path leading to and directly outside the escape window remains free of internal clutter or external blockages
Making sure that if window locks require a key or specific tool to open in an emergency, the key or mechanism is accessible to tenants
Ensuring that properties comply with local building regulations regarding egress window size, height, and positioning relative to safe ground and rescue ladders
Document and regularly review escape routes and window accessibility as part of the property’s overall safety evaluatio..

HMOs

In an HMO (House in Multiple Occupation), fire escape window compliance is vital, and local authorities may inspect the premises or request improvements as part of the licensing process or fire risk assessment.

Can A Fire Escape Window Be Restricted?

This is a common question asked by parents of young children. You want to make sure that your children are safe, and that the window will not open far enough to fall through, but that it will still open fully in the event of an emergency.

You can fit restrictors where required, but they must be ones that an adult can override quickly without tools.

From a Building Regulations point of view, restrictors that limit the initial opening to 100mm for child safety are allowed, as long as an adult can release them to give the full opening where needed.

Restrictors are standard on most modern uPVC and composite windows.

Are Fire Escape Windows Required On Single Storey Dwellings and Bungalows?

Typically, no. All rooms in a bungalow are on the ground floor, and occupants will have direct access to exterior doors and ground-level windows. There is no upper storey where a fire could cut off normal escape routes.

The only exception is if the bungalow has rooms in a converted roof space. Adding habitable rooms above the ground floor means fire escape window regulations apply in the same way as a two-storey house.
