FAQ: Will I Need Building Regulations?

When converting a glass/polycarbonate conservatory roof to a solid system you will require building control sign off. The LEKA system is JHAI approved. JHAI approval provides a fast and simple process that provides peace of mind that every installation is provided with a compliant building control certificate.

In your search for a new roof you will probably comes across systems that are LABC (Local Authority and Building Control) approved. Be aware that if you are changing from a poly/glass roof to an LABC tiled system, you WILL STILL REQUIRE BUILDING CONTROL APPROVAL & CERTIFICATION.
