Complying With Building Regulations When Installing Double Glazing Windows

Does fitting new windows and doors require planning permission or building regulations approval?
Most people are used to being able to carry out home improvements in their properties without the need to adhere to certain building regulations.

Of course, most of us know that planning permissions and regulations play a big part in major improvements such as extensions and conversions. However, for smaller jobs, most homeowners tend to simply get on with the work under the assumption that no rules or regulations have to be adhered to.

Well, if you are thinking of installing double glazing at your home in a bid to make further improvements to the property, it is important to bear in mind that this will need to comply with current Building Regulations. However, some double glazing grants might apply to your home if you're looking to improve your home's EPC rating.

The government has developed policies that are designed to boost the chances of meeting energy saving targets on a national and global basis. In order to do this, it has become increasingly important to gain greater control over energy efficiency in homes across the country.

While glazing in new build homes can be controlled more easily by Building Regulations as the properties are being built, in older properties where occupants are arranging the replacement of windows and doors themselves adherence to regulations has to be proven.

Proving compliance with Building Regulations

It is important that your replacement windows are able to reduce energy loss, not just for your benefit but also to adhere to government policy. With this in mind, your replacement windows need to comply with the thermal performance standards that are in place.

In order to demonstrate compliance, there are a couple of methods that you can use. The method you opt for will depend on who has actually installed your new windows and doors. These are as follows:

    • Registered installer: If you decide to have your windows installed by a specialist company or fitter that is registered with FENSA or a similar authority, you simply need to obtain a certificate showing that the installation has been performed by a registered professional. You will need this certificate in the event that you decide to sell your home or in other circumstances where you may need to prove compliance with Building Regulations.
    • Self-installation: If you have decided to install your windows and doors yourself or are using someone who is not registered, you will need to obtain a certificate from the Local Authority to confirm that the installation has received approval under the Building Regulations. It is important to remember that you will need full Local Authority Building Control approval if you are installing the windows and doors yourself or using someone who is not registered.

For most people, the easier option in order to ensure compliance with Building Regulations is to use a registered installer, as this saves the homeowner time, hassle, and inconvenience. It also means that you are less likely to experience problems and issues with the installation of your double glazing, so you can enjoy all of the benefits without worrying about substandard workmanship.
