Building control for roof work in Stroud: GBCP explained

Stroud District Council's own building control page says that a partnership arrangement exists between Stroud District Council and Gloucester City Council to deliver the service as the Gloucestershire Building Control Partnership, or GBCP. Applications are made through the partnership's website, gbcpartners.co.uk. Gloucester City Council's contacts page lists the same service, based at Ebley Mill in Stroud.

In practice that means the person who deals with your roof in Stroud, Stonehouse or Nailsworth is the same team that serves the city of Gloucester. You can reach them on 01453 766321, and the partnership's site gives an email address for enquiries. Stroud is a town and Gloucester is a city, and the partnership covers both areas.

Neighbouring districts are organised differently: CTBC serves Cheltenham and Tewkesbury, while the Forest of Dean has its own team. The body that applies follows your property's address, not the roofer's base.

Not every roof job does. The Planning Portal says no application is normally needed when the work touches under 25 per cent of the building envelope and under 50 per cent of the roof. Go past either figure and approval is required, with Part L possibly adding an insulation upgrade.

Other triggers are structural alterations, a covering with a very different fire rating, and a heavier covering: 15 per cent more weight or beyond. Going from a light tile to stone can cross that line, one reason like-for-like replacement keeps things simple. Solid conservatory roofs also need an application. Our page on Building Regulations for roof work in England sets out the rules in full, and this page concentrates on who you contact.

The alternative to the council is a registered building control approver, a business registered with the Building Safety Regulator under rules in force from April 2024. Pick one route per project, never both.

• The council route. Here that is GBCP. You or your builder submit a notice or application, the partnership checks the details, and an officer inspects the work at agreed stages.
• The private route. You appoint a registered building control approver, who does the same job independently and issues the completion paperwork.

Each route ends in a certificate: the council issues a completion certificate, while a registered approver gives a final certificate, which goes to the council as well. Ask your roofer which one is in use, because that tells you who holds the file, and keep a note of the reference number. Where a job is notifiable we handle the notice ourselves, and the quote names the body it goes to.

On the council's page, a notice that arrives before 15:00 on a weekday is aimed at inspection the next working day when it can be managed. That is the council's target and not a promise from us. Plan the programme around it rather than counting on a precise slot.

For roof work, inspections usually fall at points where something is about to be covered. With a re-roof, that is typically when the old covering has gone and the structure and new underlay are visible, and again when work is complete. Tell your roofer when you want the officer, so the work is not covered before they look.

If you use a private approver, their booking arrangements are their own, so ask them when you appoint them. Forest of Dean District Council, for example, says that a call before 3pm will usually allow an inspection the next working day, but that is a different district with a different service.

Building control and planning are separate systems, and passing one does not satisfy the other. Building control checks that the work is safe and meets technical standards. Planning decides whether the work is acceptable in principle, and Stroud District Council remains the planning authority even inside the Cotswolds National Landscape.

That matters because a large part of the district sits in the designation. Dormers and cladding lose permitted development there, while roof windows and like-for-like re-roofing usually do not, as we explain on our page about the Cotswolds National Landscape and roof work. In five of the district's conservation areas, Article 4 directions apply as well, covered in Article 4 directions in Stroud. Either way, raise it with the planning team before any work begins.

When notifiable work finishes, the body you used issues the certificate. It is the proof that the roof was inspected, and it is the document a buyer's solicitor looks for. Keep it with your guarantee and the invoice.

If the certificate is missing, GBCP can say what is held on its file for your address, and a private approver will have kept its own. Ask well before any exchange of contracts.

When you ring the partnership, have the address, a short description of the roof work and the start date to hand; they will tell you whether a notice or a full application is needed and what it costs, since fees are set by the body and vary with the job. Keep a note of the officer's name and the reference number you are given.

You can reach us on 01453 933613 or through the enquiry form with questions about whether your job is likely to be notifiable. The survey settles it, and the answer goes into the quote. See also the Supreme Roofing home page for the roofing work we cover.
