A home renovation is easier to control when important decisions are made before they become urgent. This Before You Renovate Knowledge Centre article is designed to help UK homeowners understand the practical questions to consider, the records to keep and the decisions to make before committing significant time and money.

What Building Regulations are for

Building Regulations set requirements for building work covering matters such as structure, fire safety, ventilation, energy efficiency, drainage, electrical safety and accessibility. They are distinct from planning permission.

Alterations can require approval

Building Regulations are not limited to new houses and extensions. Many alterations to existing homes can fall within the regulations, including certain structural changes, services, windows, heating work and bathroom or electrical work.

Competent person schemes

Some types of work can be self-certified by installers registered with an appropriate competent person scheme. Keep the resulting certificates with your property records.

Application routes

For work that is not a higher-risk building, approval may be obtained through a local authority building control body or a registered building control approver, depending on the circumstances and jurisdiction. Different application routes are available for different projects.

Inspections do not replace the builder's responsibility

Building control involvement is important, but it should not be treated as continuous quality supervision of every aspect of the project. The people carrying out and commissioning the work still have responsibilities for compliance and quality.

Keep the completion information

Completion certificates and trade certificates can be important when selling or refinancing a property. File them with drawings, warranties and other handover records.

Check the rules for your project

Requirements differ across the UK and can change. Confirm the current route and requirements for your location and specific work before starting.

The Before You Renovate approach

The purpose of good renovation planning is not to remove every uncertainty. It is to identify the important ones early, make informed decisions and keep control of cost, scope and responsibilities as the project develops.
