The costs associated with building regulations approval can vary greatly, depending on the size and complexity of the project. For a typical residential extension or new build home, the costs can range from £200 to £1000. This includes the application fee, which is usually around £100 to £200, and the inspection fee, which can be between £200 and £800. The inspection fee covers the cost of the building control officer's time to visit the site at various stages of construction, checking that the work complies with building regulations.
In addition to these costs, you should also consider the charges for any additional tests required by building regulations, such as air tightness testing or sound insulation testing. These tests can add an extra £200 to £500 to the total cost. If your project involves more complex elements, such as structural alterations, you may also need to factor in the cost of a structural engineer. This can add another £500 to £1000 to your budget.
It's important to remember that these costs are estimates and can vary depending on your local authority and the specifics of your project. It's always a good idea to get a detailed quote from your local authority or a private approved inspector before starting work. Also, remember that these costs are often dwarfed by the expense of having to rectify work that doesn't comply with building regulations, so it's worth investing in getting it right first time.
