You'll usually have access to insurance-backed warranties and a robust complaints procedure to use in the unlikely event that work is found to be non-compliant.
An installer registered with a competent person scheme will notify the local authority on your behalf and will issue you with a certificate on completion. This can be used as proof of compliance. It'll also show up on a solicitor's local authority search when you sell your home.
If you don't use a registered installer you'll have to submit a building notice or full plans application and pay a fee to building control for inspection of the work you've carried out.
How to find a registered competent person:
- for electrical work, please visit the competent persons register
- for roofers, please visit competent roofers
- for all other types of work, please contact the competent person scheme operators
