Building Control Applications


Most building works (with a few notable exceptions) require Building Regulations Approval.


There are two main routes to this, these are through the submission of either a Building Notice or a Building Control Full Plans Application.





 GPO Designs offer two Building Control Full Plan Application Services ...


 Single storey extensions or small projects- for only 500 (including VAT and online discount).


 Larger extensions and loft conversions -for only 900 (including VAT and online discount).



Building Control Full Plans Application Service


The Full Plans Application process requires the production of fully detailed plans providing details of the construction materials (including dimensions and strengths), detailed specifications and structural calculations. The Local Authority then review the plans for compliance with the Building Regulations and providing the plans are compliant (and complete) they permit work to proceed in accordance with the plans. The Local Authority inspects the work as it proceeds at the same stages as they do with the Building Notice.


Full Plans Applications are highly recommended for new build projects and for very complex projects. They are essential where Building Notices are not permitted.


GPO Designs typically take two weeks to complete a Full Plans Application and Local Authorities take around five to eight weeks to review and approve the plans.


GPO Designs can produce and submit your Full Plans Building Application for only 500 (single storey extensions and small projects) or 900 for larger extensions and loft conversions. This excludes the Local Authority Building Control Full Plans Application Fee which is priced based on the type and/or scale of the works. Structural calculations (where required) will be subject to additional charges to be paid directly to the Structural Engineer. (Terms and Conditions apply. This offer is only available where we have produced the Planning Application.)
