What are building regulations?

Building Regulations are:


  • A set of procedural requirements that must be followed by anyone intending to undertake any proposal defined under the regulations as building work. 

  • A set of functional requirements that completed building work must deliver in order to achieve reasonable standards of health, safety, welfare and convenience of people in or about buildings. 


The scope and extent of building projects covered by the building regulations is defined in Regulation 3 of the official building regulations​​​​​​​​​​​​​​​External link opens in a new window​​ themselves. 


Your architect/designer or builder will usually check if you need building regulation approval, but it is the building owner, or the person who commissions the work, who is ultimately responsible for ensuring this is obtained.


Highly qualified and experienced teams of surveyors in the Council’s Building Control Section will examine plans, carry out site inspections of work in progress and assist you at all stages of the both the procedural and construction processes. 


Please note that Planning permission​ is not the same thing as approval under the building regulations. In the majority of cases both permission to carry out building work i.e. Planning Permission, and approval under the building regulations i.e. how the building will perform when completed, will be required. 


However, there are exceptions and it is possible for certain types of building project to need (planning) permission but not building regulation approval and for some types of building project to need building regulation approval but not (planning) permission. It is advisable that unless you, or your advisers, are certain that advice is sought from the Council as any work carried out without the relevant permission and/or approval can be required to be altered or removed.  


What is the cost of Building Regulations Approval?

The cost of the building regulation approval process varies depending on the type, nature and extent of the building work you propose to carry out. 


The charges are governed by the Building (Local Authority Charges) Regulations are determined by a number of factors defined in these regulations. Some of the charges applicable can be obtained from our standard table of c​harges. It is not possible to list all of the charges for all of the combinations, types and scales of building work possible. Please contact us for further advice and guidance.
