BUILDING CONTROL
Making building control approval simple and stress-free for your warm roof projects...
That’s why we have developed a simple, streamlined process that takes all the hassle away. Every Thermacore Warm Roof has been independently tested and certified by LABC. This includes thorough structural calculations, detailed thermal performance checks, condensation risk analysis, and full verification of the complete system - all carried out by independent experts. As a result, the Thermacore Warm Roof holds full System Approval, giving you complete confidence and making building control approval quick, easy, and stress-free from start to finish!
We have a dedicated in-house team with expert product knowledge who manage the full process, from application to approval.
We cover the entirety of England and Wales.
Yes. We provide pre-application advice to help avoid delays or unexpected costs at the quoting stage.
Applications must be submitted before any work starts on site. We require at least 5 days’ notice to register your application.
Unfortunately, if work has already started, we cannot fulfil the building control application.
Complete the application form in full and we will submit it directly to our partnered building control authority. They will then register the application with the local authority responsible for your site address. When you're ready for an inspection, simply contact your local authority to arrange a site visit. During the inspection, the local authority will verify that the roof installation matches the specifications and details provided as part of your application, confirming compliance with building regulations in coordination with our building control partners.
Certification will be issued once the site inspection has been completed and verified by our partnered building control authority. It will then be sent over to you!




Fully

A ThermaCore Warm roof comes to site 80% complete, the only things you will need to complete the installation are fixings to fix the roof to the house wall, lead flashing and plaster to finish inside!
Yes, we offer guided installs! We also have a technical helpline, so anytime you have a question, we have an answer!
Yes, we meet building regs for U-values in England, Wales and Scotland and we are prepared for the next increase due in 2025!
Firstly, it’s made from timber so is up to 800 times less conductive than aluminium meaning there is no hot and cold bridging and no condensation issues. It has also been designed so no insulated-plasterboard is needed to hit the all-important 0.15 U-Value, so our roofs can be finished with a 12.5mm Plasterboard!
The ThermaCore Warm Roof comes as standard with Britmet shingles or liteslates. Ther Low Pitch Roof is finished with our Low pitch roof sheets, but can supply different tiles if required (including concrete tiles if the supporting structure is strong enough for the additional weight)
Just like traditional conservatory, we base everything on internal frame sizes. It is always best to provide the correct pitch as well, but we can help with that!
Every Thermacore Warm Roof has been independently tested and certified by LABC. We also handle all building control matters in-house, so if your project requires submission to building control, just let us know - we’ll take care of everything.
