Building Regulations for structural work in Trowbridge are handled by Wiltshire Council's building control team.

To apply, contact Wiltshire Council's building control team directly or submit an application through the Planning Portal at www.wiltshire.gov.uk.
Common questions
Do I need a structural engineer to remove a load-bearing wall in Trowbridge?
The Planning Portal advises that a structural engineer or surveyor can determine whether a wall is load-bearing and design a suitable beam for the loads involved. It recommends speaking to one before starting any work. Removing a load-bearing wall usually requires building control approval, though it is building control that decides what is needed in each case. Getting an engineer involved early helps ensure any beam design meets the required standard.
How do I apply for building control approval in Trowbridge?
You can contact Wiltshire Council's building control team directly or apply through the Planning Portal. There are two main routes: a full plans application, where a decision is expected within five weeks (or two months with your consent), is the more thorough option. A building notice suits smaller projects, work can begin two days after submission, and there is no formal approval of plans. Building control decides which route is appropriate for your project.
How do I check a structural engineer in Trowbridge is chartered?
The Engineering Council's RegCheck tool lets you confirm whether an engineer's CEng or IEng registration is currently active. The Institution of Structural Engineers (IStructE) and the Institution of Civil Engineers (ICE) also publish member directories you can search. Sixteen firms listed for Trowbridge state chartered status on their own websites, but this has not been independently verified, so checking directly through these official sources is advisable before appointing anyone.
Do I need to tell my neighbours before structural work on a shared wall?
Under the Party Wall etc. Act 1996, if you plan to carry out work on a party wall you must give your neighbour at least two months' notice before the start date. For a new wall on the boundary line or excavation near a neighbour's building, at least one month's notice is required. Serving notice correctly before work begins is a legal requirement under the Act, so it is worth checking which notice applies to your project.
