Building Regulations control the standards for the design, construction and alterations to every building in the UK. Approved by Parliament, the association was developed by Government to ensure all buildings meet certain safety and security standards.

UK Building StandardsThe Building Regulations also set the standards for energy efficiency, sustainability of buildings as well as the misuse and contamination of water supplies.

These regulations must be met on any new development or extension to your home. They cover all aspects of construction from foundations to insulation and ensure that quality facilities for those with disabilities are provided in every commercial building.

Before you go ahead with any home improvement, you must ensure all work is in accordance to their standards. The Building Regulations are regularly updated so make sure you keep yourself well informed. 

Windows & Doors

Building Regulations state that certain standards must be met when a window or door is replaced. An external window or door under the current set of Building Regulations is considered a “controlled fitting.”

It has been a legal requirement since April 2012 for all uPVC window installations in the UK to be fully compliant with current Building Regulations. If an installation does not comply then the homeowner as well as the installer could be liable for prosecution.

Trusted Double Glazing Installers

Windows and DoorsDouble Glazing on the Web insist that all of our trusted local installers and suppliers are registered with an industry recognised body such as CERTASS or FENSA.

As a result, every installation receives a certificate from the relevant industry body whilst being registered with the local authority. Rest assured all work carried out by our members is fully compliant with current building regulations.

Your Trusted Local Supplier will register the work with a regulatory body on your behalf so you will not need to worry about any of the red tape or paperwork.

They should provide you with your certificate on completion of the work. This is an important document as it verifies that your installation adheres to building regulations and that the work meets necessary standards of practice.

Building Regulations and Energy Efficiency

The Government has also altered Building Regulations regarding the energy efficiency of houses in England and Wales. The details of these changes can be found in Part L of the Building Regulations.

The aim of these changes is to make housing throughout England and Wales more energy efficient and therefore reduce the negative impact they have on the planet.

Building Regulations and Energy EfficiencyIn essence all double glazing must be:

• Governed by current Building Regulations which require Local Authority Building Control approval prior to installation.

• In accordance with higher energy efficiency standards.

If you choose an installer who is registered with a competent person scheme such as FENSA, Certass or BSI then they will take care of Building Regulations on your behalf.

An installer such as this will be able to provide evidence that all their work adheres to current Building Regulations, without the need to involve local authority building control.

Once your installation is complete, you will be provided with a certificate which acknowledges the quality of work.
