Using registered contractors

Using a registered builder protects you if there is a dispute. For example, if your contractor goes out of business or fails to complete the work, the scheme who registered the contractor will arrange for the work to be completed.

You should contact the relevant scheme if a problem arises.

Building work

Where the approved cost exceeds £5,000 you must use a builder who is registered with one of the following recognised warranted builders schemes:

Electrical work

A qualified electrical contractor must carry out all electrical and provide a completion certificate when the work is finished.

Treatment for rising damp and wood rot

A specialist contractor must carry out these types of work and provide a guarantee for at least 15 years.

Standard of work

We are not responsible for the standard of your builder’s work.  It is your responsibility to check on the standard of work. You may find it helpful to employ an architect, surveyor or other professional to supervise the work for you.


We recommend that you get estimates for the work from a number of local builders. This will help you make sure you get the work completed at the best price.

Replacement Grant

If you have received approval for a Replacement Grant, you must use a builder who can provide a 10 year guarantee when they complete the works.

The builder must be registered with one of the following schemes:
