Quick summary

Building regulations approval is a legal requirement for most construction projects, costing around £600 to £1000 depending on size and scope, usually taking up to five weeks for full plans. It’s needed for new builds, extensions, loft conversions, and certain installations. Some small jobs or internal changes may not require approval, but it's best to check.

You’ve got your plans approved, so what happens next? More paperwork - hurray!

However much you may want to zoom past the ‘boring bits’, and get straight to building and kitting out your new space, we cannot stress enough how important it is to be vigilant at nailing down your building regulations approval. Building regulations approval is the step a homeowner takes between acquiring planning permission and appointing a builder for your project. Luckily for you, we’re here to lend a helping hand on getting you up to scratch on how and where to do so.

Why do they matter?

Getting building regulation approval is a statutory requirement set by the government in order to ensure that buildings are designed and constructed in accordance with the Building Regulations & Associated Legislation. Approval is predominantly necessary to ensure the health and safety of those living in the property, as the regulations oversee not just the structural integrity of the building, but matters such as fire safety, energy efficiency, and sustainability. Therefore, they are not only important for day to day building matters, but have long term environmental benefits.
