New Regulations for Windows and Doors in England Summer 2022
- June 15th 2022 is the planned introduction date for these updates
- Wales is currently excluded from these plans, but may introduce the same or similar restrictions in the near future. We will of course update this article when any changes are announced
What does this mean for homeowners?
Background Ventilation
Covered under Part F - Ventilation
This basically means that new windows in both existing and new homes will require the inclusion of trickle (passive) ventilation, and the amount of ventilation required will depend on the room status
Basically, all rooms with walls require background ventilation
Multi-Storey Homes | Single-Storey Homes | |
Habitable Rooms | 8,000mm2 | 10,000mm2 |
Kitchen (not open plan) | 8,000mm2 | 10,000mm2 |
Kitchen (open plan) | 24,000mm2 | 30,000mm2 |
Utility Room | Not required | Not required |
Bathroom | 4,000mm2 | 4,000mm2 |
Ensuite / Enclosed | Add +4,000mm2 to another room | Add +4,000mm2 to another room |
Sanitary Room | Not required | Not required |
Exception, if the total number of ventilators installed in a home's habitable rooms and kitchen are fewer than 5, then 5 must be the minimum except in single bedroom properties where there is a minimum of 4 background ventilators within the property
What if we have continuous Mechanical Extract Ventilation installed already?
If you already have a Mechanical Extract Ventilation system installed then a reduction or removal in the need or performance of the background ventilators may be permitted
Continuous Mechanical | Continuous Mechanical with Heat Exchange | |
Wet Rooms | Not required | Should not be installed |
Habitable Rooms | 4,000mm2 | Should not be installed |
However, the Mechanical or Mechanical with Heat Exchange system needs to comply with the minimum air exchange requirements indicated within the official document linked to - and professional advice may be required to confirm this
Covered under Part L - Air-tightness
Windows and doors must connect to the main (primary) air barrier and the windows and/or doors taped to the surrounding structural openings using an Air Sealing Tape, with the option of using supplemental taping by use of gun sealants or compressible seals if required
Your window and door installer should incorporate this method of fixing and sealing into the project as standard,
The requirements for Windows and Doors will be
U-Value | BFRC Energy Rating | |
Windows | 1.4u | Band B or above |
Doors with 60% or more glazing | 1.4u | Band C or above |
Doors with less than 60% glazing | 1.4u | Band B or above |
Of course, when you order your installed Windows and Doors through Heronhurst, and installation is by us and within a domestic home and within the dates of these new regulations, we will ensure every requirement is met, and certification to back this up, for your peace of mind

Condensation on the outer panes of windows
Covering the topic most popular this time of year, Condensation on the outer panes of a window
Click here to download your PDF or read below to learn the reasons why sometimes we all can get external condensation on modern, energy efficient windows
Or read the GGF Guide here
My windows are all misted up on the outside. What’s wrong with them?
The simple answer is nothing is wrong with them! In fact, external condensation can be proof that energy efficient windows are performing well (see below).
If nothing is wrong, why is there condensation?
The longer answer is that the modern windows that FENSA Approved Installers fit these days are so much more thermally efficient than those installed in decades past. As a result, the heat used to warm homes doesn’t escape through to the outer pane
The outer pane of glass is therefore cooler and when its temperature falls below dew point, moisture in the air condenses on it
Why does condensation only form at certain times of year?
The reason window condensation can be worse during Autumn
(and Spring) mornings is that at these times of year the temperature of the glass can really drop overnight, yet the dew point remains relatively high
Some windows can be affected more than others and slight changes in orientation or shelter can mean that windows or even panes next to each other can react differently
What can I do to stop external condensation forming?
Unfortunately, there is not much that can be done to stop this phenomenon. It usually doesn’t last long and shows that the heat being used to warm your home is being saved rather than lost through your windows - thus potentially lowering your heating bills and reducing your home’s carbon emissions

The New Green Deal and Wales
- Updated 13.10.2020
As per our recent communications, we are very pleased to confirm that, in line with government guidance, home energy-saving improvements carried out under the new Green Homes Grant scheme must be completed by a TrustMark Registered Business.
This represents a significant opportunity for businesses that complete the following works:
- Solid wall, under-floor, cavity wall or roof insulation
- Air source or ground source heat pump
- Solar thermal
In addition, households can use their voucher for further energy-saving measures. These include one or more of the following, providing more opportunities:
- Double or triple glazing/secondary glazing, when replacing single glazing
- Upgrading to energy-efficient doors
- Hot water tank/appliance tank thermostats/heating controls
----
The government is today setting out further details of the range of measures included and how consumers in England will be able to claim the new vouchers, which are worth up to £5,000 for homeowners. Households on low income can receive vouchers covering 100% of the cost of the improvements, up to a maximum of £10,000.
Facts from this document
- Wales is not included in this deal
- Double or Triple Glazing can only be added to another higher priority home improvement
- Double or triple Glazing must be upgrading from single Glazing not old double glazing
- Heronhurst are established members of Trade Mark and can help providing you are located in an area of England we cover and meet all other requirements
Unfortunately for most people this means this deal is out of their reach
Face Masks become compulsory
The only exception is on genuine health reasons
Disposable masks are available in-store for visitors should they not have them
Thank you for your co-operation and understanding
