Common questions
Do I need a structural engineer to remove a load-bearing wall in Wincanton?
The Planning Portal advises that a structural engineer or surveyor can determine whether a wall is load-bearing and design a beam suited to the loads, and recommends speaking to one before starting any work. Removing a load-bearing wall usually requires building control approval, though building control decides what is needed in each case. Of the fourteen firms listed for the Wincanton area, seven say they carry out beam calculations and ten say they handle extension design.
How do I apply for building control approval in Wincanton?
You apply through the Somerset Building Control online portal at buildingcontrol.somerset.gov.uk, which accepts Full Plans, Building Notice and Regularisation applications. Full plans is the most thorough route, with a decision expected within five weeks or two months with your consent. A Building Notice suits smaller domestic projects only; work can start two days after submission and there is no formal approval of plans. You can also use a private registered building control approver for work that is not higher-risk.
How do I check a structural engineer in Wincanton is chartered?
You can use the Engineering Council's RegCheck tool to confirm whether an engineer's CEng or IEng registration is currently active. The IStructE and ICE also publish member directories you can search. Bear in mind that the chartered status information shown on this directory reflects what firms state on their own websites and has not been independently verified. Four of the fourteen firms listed for the Wincanton area state that they hold chartered status.
Do I need to tell my neighbours before structural work on a shared wall?
Under the Party Wall etc. Act 1996, you must give neighbours notice before carrying out work to a party wall. Notice must be given at least two months before the planned start date for work to a party wall, or at least one month before for a new wall on the boundary line or excavation near a neighbour's building. If a neighbour disputes the work, a party wall surveyor may need to be appointed. The Act applies regardless of whether planning permission is required.
