A particularly popular addition to kitchen area, bi-fold doors offer the ultimate wow factor for those looking to bring their home into the 21st century or take full advantage of a beautiful view. Bi-fold door systems are available in a selection of finishes to complement both modern and traditional interiors, and ensure that your family friendly living space is fully flexible.

As with any home upgrade however, you may be put off by the prospect of obtaining planning permission. Here we take a closer look at whether planning permission and Building Regulations are needed for bi-fold door installation.

Planning permission for bi-fold doors

As the addition or amendment of exterior doors and windows is considered a permitted development, planning permission is not usually required. It is important to remember however that your Local Authority will get the final say on any permitted development rights, and they can choose to revoke or amend terms accordingly. Bi-fold door installations that form part of a wider extension may also need planning permission. For more information on bi fold door installation visit Eco Bifold

Bi-fold door installations in flats or apartments are a little difference. As flats do not have permitted development rights, you will need to apply for planning permission.

I live in a conservation area, do I need permission?

Those living in conservation areas may also have to seek advice from their Local Authority before installation can begin and whilst you may not need planning permission you may need other consent if your building is Grade 1 or 2 listed. Special clauses may come into effect if you live in a conservation area, for example, many Local Authorities prefer the use of timber framing in conservation and other designated areas.

A word about Building Regulations

Building Regulations need to be considered when choosing your glazing system. Any bi-fold door must comply with Document L of current Building Regulations, this dictates thermal efficiency. Thermal efficiency is particularly important meaning the use of single glazing is not permitted. Double glazing is the minimum requirement for bi-folding systems, whilst triple glazing provides the lowest U-value (therefore the highest thermal efficiency) compared to other glazing options.

The glazing of your bi-fold doors must also comply with Document N of Building Regulations, this provides guidelines for safety regarding a bi-folding system’s impact, opening and cleaning.

It is recommended that you check with your Local Authority before starting any home upgrade regarding whether permission is required.
