LABC Council Building Control vs JHAI Approved Inspector for Solid Conservatory Roofs
Do I need Building Regulations approval to put a solid roof on a conservatory?
Yes. Under the 2010 Building Regulations (as amended), replacing a translucent conservatory roof with a solid tiled roof removes its thermal exemption. You must obtain a Final Completion Certificate from either your local council LABC (£320–£450) or an accredited Approved Inspector such as JHAI/Assent (£350–£395), or solicitors will block your property sale until you purchase indemnity insurance.
| Approval Route | Typical Inspection Fee | Turnaround & Conveyancing Acceptance |
|---|---|---|
| JHAI / Registered Approved Inspector | £350 – £395 (Bundled by Certified Installer) | Fast 5-Day Digital Sign-Off • 100% Solicitor Accepted |
| Local Authority Building Control (LABC) | £320 – £450 (Paid to Council) | Requires 2 On-Site Visits (Pre-Plaster & Final) |
| Retrospective Regularisation (Unapproved Roof) | £550 – £850 + Invasive Core Holes | High Risk — Requires Exposing Insulation & Rafters |
