Building Regulations

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.

The 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

Double Glazing on the Web insists 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.

In 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.

Conservatories

Planning Permission and Building Regulations for conservatories can be a tricky subject. This is why it’s important to refer to the most relevant and up-to-date information.

This is why we recommend the Government’s Planning Portal. It is the best source of information for Planning and Building Regulation information for conservatories, orangeries and extensions.

What is a Conservatory?

Generally, a conservatory is seen as a build that is substantially glazed. Glazing makes up 50% of new walls, with 75% of the roof being glazed with either transparent or translucent materials.

The market for glazed extensions however, has developed and matured over the years. Enhancements have been made to the standard conservatory, meeting the demand for the aesthetic aspirations for today’s modern homeowner.

Having focused on improved aesthetics and functionality, these enhancements have created a cross-over between a conservatory and orangery.

Enhanced conservatories often incorporate additional external lightweight guttering or facade details. They may also feature internal pelmets around the perimeter of the conservatory with lighting features such as down lighters.

Enhanced conservatories will require Building Regulation approval through a recognised Building Control Body.

Due to the accepted definition of a conservatory, these roofs are still substantially glazed however, modifications and the intended use may result in a conservatory no longer meeting the requirements for exemption from Building Regulations.

A Permitted Development

Building changes to a dwelling can be made without applying for planning permission. These are allowed under Permitted Development Rights.

A conservatory is considered a permitted development, not needing an application for planning permission. However, if your answer is yes to the following then planning permission may be required.

  • Will your conservatory be seen from a road or public right of way?
  • Have you had any previous extensions?
  • Is your property a listed building?
  • Are you located within a Conservation Area or an area of Outstanding Natural Beauty (ONB)?

Click here to read more on conservatory requirements.

Planning regulations require all new extensions to be designed to match the existing house. Any new materials used must match as close as possible to the existing structure. This requirement also applies to buildings under permitted development rights.

A full planning application is usually processed within 10-12 weeks.

Responsibilities

Your contracted retailer has the responsibility for ensuring the compatibility of all components used on the installation. This also includes the overall structural integrity of the structure. The contract should make clear the scope of the works that the retailer is responsible for.

Neighbours

Your neighbours should be informed about the intended work. If the intended conservatory overshadows a neighbour’s window, you may be affecting their ‘right to light.’ This could result in legal action so it’s important to consult with your neighbour before going ahead with installation.

Orangeries

Today’s Orangery design has been developed into a contemporary, fully structured building.

There are generally two types of orangery:

  • A structure built with brick piers and a parapet wall above the perimeter flat roof with roof lights incorporated into the roof.
  • A structure using similar flat roof technology with roof lights or lanterns but has the roof fitted to a directly glazed wall frame or solid infill panels and corner panels.

You will require Building Regulations if:

  • The orangery is opened permanently to the existing house
  • It does not meet the general glazing requirements of a conservatory

Porches

Adding a porch to an external door is considered to be a permitted development providing certain limits and conditions are met.

A porch is exempt from planning consent as long as it is subject to the following:

  • The ground area has been measured externally and doesn’t exceed 3m2
  • The highest part of the porch does not exceed 3m
  • The porch is not within 2m of any boundary that fronts a highway
  • It is seen as the homeowners’ responsibility to confirm whether the Permitted Development rights have been removed from the property.
