Once you have secured your planning permission, Building Regulations approval is needed. We can prepare and these for you and at the same time submit them for SAP/EPC, water and air tightness calculations on your behalf - you simply pay the fee to your preferred provider.
Our fees for Building Regulations do depend upon whether we have created the drawings for your extension or new house. Our charge for the energy compliance calculations is at cost.
Building Regulations - From Our Plans
Outbuildings: from £650
Extensions: from £800
New Build: from £1200
Our fees for building regulations are in addition to Building Control's fees which through Cornwall Council range from £426 to £556 for an extension and £852 for each new house.
Building Regulations - Plans by Others
If we are working from plans created by someone else, we have to recreate them and this incurs a charge for our time.
If your designer can provide you with an electronic copy of your plans (DWG file or DXF file) we can reduce the amount of extra time involved and our fee is proportionately reduced. As a guide our fees (from electronic copies) are as follows:
Outbuildings: from £800
Extension : from £1500
New Build : from £2000
These fees are in addition to Building Control's fees which through Cornwall Council range from £426 for an extension and £852 for each new house.
