Window regulations England

All replacement windows and doors in England must adhere to certain performance standards. In particular, this applies to thermal efficiency, safety, and some other key areas. Let’s take a closer look at these Building Regulations

Thermal Heat Loss

The energy efficiency of any new windows in England is determined by the amount of heat loss they allow. This is measured as U-Value. The lower the U-Value, the less heat is lost. In England, the maximum U-Value a window can have is 1.4W/m2K or minimum Window Energy Rating (WER) band B.

Safety glazing

Safety glazing is required for certain properties which could be vulnerable to break-ins or breakages, i.e. those on street level. For this, laminated or toughened glass should be used. The exact conditions for new windows that should have this are as follows: 

  • Any window panel up to 800mm from ground level
  • Any side panel up to 300mm from the edge of the door, up to 1500mm from floor level.

Ventilation

Windows and doors must provide a minimum amount of ventilation to a given room, the extent of which mainly depends on the room’s size or its function. Kitchens or bathrooms in particular require extra ventilation given the amount of steam they can produce. 

Fire Safety

In cases where fire can spread between properties is a particular risk or there are fewer escape routes, new windows may be required to be fire resistant or fixed shut. 

Means of escape

In most cases, the size of your replacement windows should match or exceed those that they replace to provide the same potential for escape. For new windows, certain conditions may have to be met to provide your home with a potential escape route. These include:

  • A minimum width and height of 450mm 
  • A minimum openable area of 0.33m²
  • A maximum height of 1110mm above the floor

A FENSA registered installer, or equivalent certification body, means the installer has adhered to these regulations and means you won’t need to apply for any planning permissions or involve a local council. 

You can be sure that they have installed it according to these standards by the certificate they will offer at the end of the project. If you ever go on to sell your property, you will need this as evidence that your windows meet all the necessary Building Regulations in England.

All fo the installers in our network are vetted by us and FENSA qualified. You then have the chance to find a good deal by comparing their offers and choosing the most competitive option.

Window regulations for rented properties England

New and replacement window regulations for rented properties in England are the same as outlined above. For those living in a rented property, it can be good to know some of the key window regulations in England that landlords are obliged to follow when it comes to the windows in the property. 

Some of these include: 

Windows

  • Ground floor opening windows must have window locks or cable restrictors for child safety.
  • 1st floor and above opening windows should have secure window restrictors or locks for child safety.
  • All windows should be in good working order, and each room should have at least one window that opens.

Glazing

  • Replace any broken or cracked window panes before letting.
  • Interior doors with glass panels should have safety glass or be protected and boarded over.

Insulation

  • Improve properties with EPC ratings of F or G before renting out for new tenancies.
  • Repair broken windows and doors.

Ventilation

  • Ensure proper ventilation in the property.

Safety and security

  • Install restrictors or safety rails on large low-level windows.
  • Ensure escape windows can be opened easily in case of a fire.
  • Ensure windows, doors, and entry points can be securely locked.

By adhering to these window regulations, landlords can create a safe and comfortable living environment for their tenants while fulfilling their responsibilities.

Double glazing England

Double glazing is simply a window that has two layers of glass sealed within a frame. Argon gas is used to fill the gap between the panes of glass to create a thermal barrier that prevents heat from passing through it.

Upgrading your home with energy-efficient double glazed windows will help to improve the comfort and safety of your entire home. 

Benefits of double glazing

Reducing heat loss with better insulation can also drastically reduce your monthly energy bills, especially if you’re replacing single glazed windows. According to the Energy Saving Trust, replacing single glazing with A+ double glazing can reduce annual energy bills by up to £135. 

Double glazing prices England

For a single double glazed window unit, you can expect to pay between £300 – £600. Window prices in the UK mainly depend on the size and style of window you choose. Below, we’ve provided cost estimates for standard white uPVC windows.

uPVC double glazing costs

Casement £200 – £710
Sash£300 – £1,065
Tilt & Turn £250 – £890
Bay (3 panels)£1,190 – £1,725

*Estimates based on 900 x 1200mm single window units

New windows may also come in aluminium, timber, or composite material. uPVC windows remain the most popular for new windows considering it’s a highly durable, energy-efficient, and versatile material. It’s also the most affordable of all the materials available today.

Aluminium windows in the UK tend to cost between £375-£750. The most expensive material is timber, which can cost up to £900 for a single double glazed unit. 

You can also opt for various types of glass to enhance any particular feature of your new windows. For example, installing toughened glass will enhance your home’s security, whereas solar control or Low-E glass improves thermal performance.

Toughened glass£50 – £100+
Annealed glass£25 – £50
Low-E glass£30 – £60
Acoustic glass£126 – £160
