Are building regulations changing for window installers in 2024?

March 14, 2024

While building regulations won’t technically be changing this year, the Future Homes Standard for new build homes will become mandatory in England in 2025. And that will bring with it some upheaval – although maybe not as much as had been expected. 

When the recently wrapped up consultation period for the FHS was announced at the end of last year, it came with a couple of surprises. The main one being, notional values will not be changing. Despite industry predictions of the minimum U-Value for windows in new dwellings dropping to 0.8, they now look set to remain at 1.2. 

Don’t be fooled into thinking it’s a case of ‘as you were’ though. One of the other headline-grabbing statements from the report centred around the fact calculation methods will be changing – and this is definitely big news for fabricators. Here’s why:

 

Changing regulations & developments to be aware of in 2024

 

New calculation method

The calculation method for windows in new dwellings no longer allows for the use of a standard window. Instead, the value must be calculated using the exact size and configuration.

The performance of windows for the replacement market will continue to be calculated using several alternative methods, including the standard window.

 

Home Energy Model

Standard Assessment Procedure (SAP) calculations will become a thing of the past when the Future Homes Standard is introduced. The energy rating of dwellings will instead be calculated through the Home Energy Model.

While the SAP makes energy calculations using monthly criteria, this new model will be able to simulate homes at a 30-minute time resolution.

 

Material change of use

The consultation also included a section on material change of use and whether this should be considered as a new dwelling. It is proposing to  improve the performance of buildings that have been converted from one purpose to another by introducing better building standards.

This will affect current conversions, such as office to flats, house to flats etc, which often do not require planning permission. These dwellings often don’t perform as well as new builds and the Department for Levelling Up, Housing and Communities wanted to understand this more.

 

Do regulations mean a change in the manufacturing process?

The change in calculation method could prove to be a big headache for fabricators. If you have to calculate every window, in every size, in every configuration, including all the mullions and transoms that may be included, that’s a complicated calculation. A complicated calculation made even more frustrating by the fact you’re going to have to come to the system’s house in order to be able to get that information. 

Unless, of course, you’re using VEKA’s WinDoPlan software. WinDoPlan can calculate U-Values to the exact size and configuration, it will check your wind loads, it will create cross-sectional drawings, and our customers have access to it 24/7.

 

When will the Future Homes Standard come into force?

As soon as we know, you will know. 

The Government intends to publish the new regulations and associated guidance this year, with the standards set to come into force from 2025.

Rest assured, whatever shape the Future Home Standard takes, the VEKA team will be here to support you every step of the way.
