Competent person schemes
When a registered installer can self-certify covered work and what certificate to keep.
Short answer
When a registered installer can self-certify covered work and what certificate to keep.
For the planning permission side, use UKPlanningGuide. Keep that separate from building regulations approval and completion evidence.
What usually triggers extra checks
- Structure, fire safety, drainage, insulation, ventilation or controlled services
- Work already started or completed without clear records
- Missing certificates or unclear handover evidence
- Anything involving flats, higher-risk buildings or work outside England
Route options to discuss
Compare full plans, building notice, competent person self-certification, regularisation and specialist advice. The right route depends on risk, timing, drawings, installer registration and what building control wants to inspect.
Evidence to keep
- Application references and notices
- Drawings, specifications and calculations
- Inspection dates and site photos before cover-up
- Completion certificate, competent person certificate and commissioning records
Mistakes to avoid
Do not assume planning permission, permitted development or a builder's quote answers the building regulations question. Do not cover up work before required inspections. Do not rely on a certificate claim without checking who issues it and how you will receive a copy.
Common questions
Can I rely on this without contacting building control?
Use it as preparation, not permission. If the work is controlled or uncertain, confirm the route with building control, a registered approver or the competent person responsible for the work.
When is a general homeowner guide not enough?
Get specialist input where flats, higher-risk buildings, structural uncertainty, fire safety, public sewers or work outside England are involved.
