What is Building Regulations?

Building Regulations are a set of minimum standards for the design and construction of buildings. This is to ensure the safety, health and welfare of people who use and go around those buildings. They also include requirements to ensure that fuel and power is conserved and that facilities are provided for people with disabilities. Before you start any building work you need to check if you need building regulations approval. As the owner of a building you are held responsible.

What is a Building Notice?

This is generally only used when you are carrying out extremely simple building works, such as installing a new fire door between a garage and house, or removing a small internal wall. A Building Notice is a single stage method of application where you fill out an application form, pay one single fee and then Building Control come out and inspect as required.

The Building Regulation Process


A comprehensive set of plans and building regulations drawings are submitted to building control (local authority or private inspector). They will assess and check to make sure that all the necessary building regulations information is shown on the plans. They will also make sure that it fully complies with the Building Regulations.


Throughout the build process, a building Inspector will visit the site to regulate the build at the following stages – Foundation, Drains and DPC (Damp Proof Course).


If amendments are required, the local authority or private inspector will inform the applicant (or agent) of any changes needed. Once resubmitted and approval has been received, work can begin on site.
