Do replacement windows and doors need Building Regulations approval?

Yes. In England, replacement windows and external doors must meet Building Regulations for energy efficiency, safety glazing, ventilation and, for some windows, escape in case of fire. Compliance is shown either by a certificate from a competent person scheme, such as FENSA, or by building control sign-off. We'll tell you how compliance will be certified for your job before we start.

Do new windows need planning permission?

Usually not, if they are similar in appearance to the existing ones. In conservation areas an Article 4 direction can remove that right, and listed buildings need listed building consent for changes to windows and doors. In Hemel Hempstead, check with Dacorum Borough Council if your home is in the Old Town or Boxmoor conservation areas.

Window and door fitting in Hemel Hempstead: frequently asked questions

Do replacement windows need Building Regulations approval?

Yes. They must meet Building Regulations, shown by a competent person scheme certificate such as FENSA or by building control sign-off.

Do I need planning permission for new windows?

Usually not if they look similar to the existing windows. Article 4 directions in conservation areas and listed building status can mean permission is needed.

Can you fit bi-fold or sliding doors in an existing wall?

Yes, though widening an opening in an external wall is structural work that needs a new lintel or beam designed by an engineer and Building Regulations approval.

Do you fit internal doors?

Yes. Hanging internal doors, with new frames, skirting and architraves where needed, is everyday carpentry for our team.

How much does window and door fitting cost?

It depends on the number and size of windows and doors, the materials and any structural work. We give a free, itemised written quote.
