Quick summary

Building regulations approval is required for projects like new buildings, extensions, loft conversions, and fitting services such as drainage or electrical work. Typically, costs start around £600 for a standard project and can reach £1000 for larger or multiple works. Approval can take up to five weeks with full plans or just two days with a building notice, depending on your chosen process.

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.

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.
