Can a Building Control Surveyor recommend a suitable builder?

We do not recommend builders. It is important to select a builder by talking to previous clients. Please also consider the following:

  • Low estimates are not always an assurance of a good deal
  • You should agree the extent of the works with your builder at the outset by agreeing a simple contract with your selected builder
  • This contract can include, for example, the estimate, likely duration of the works and details of when payments are due
  • As soon as the works are completed to Building Control's satisfaction they will issue a Completion Certificate. Try to agree with your builder to defer your final payment until they have issued their Certificate
Why does the Building Control Surveyor always talk to the builder and not directly to me?

Many clients prefer Building Control to deal directly with the builder, if you wish to be involved in any on-site discussions please make them aware from the outset. If at any time you wish to talk to a Building Control Surveyor in confidence please do not hesitate to contact Building Control direct using the contact details in your application paperwork.
