Do I need building regulations approval?
The Building Control Team works to ensure that the minimum standards are achieved to protect the health and safety of people in and around buildings.
If you are considering carrying out work which involves the erection, extension or alteration of a building, you must let us know.

When you need approval
Most building work requires approval under the Building Regulations 2010. These detail the minimum level of standards acceptable, in order to ensure health and safety, conservation of fuel and power, and access and facilities for the disabled.
In addition to construction and extension of buildings, you might also need building regulations approval for alteration projects, including:
- replacing fuse boxes and connected electrics
- installing a bathroom that will involve plumbing
- changing electrics near a bath or shower
- putting in a fixed air-conditioning system
- replacing windows and doors
- replacing roof coverings on pitched and flat roofs
- installing or replace a heating system
- adding extra radiators to a heating system.
Applying for building regulations approval
If you’ve already started work or completed your project without submitting full plans or a building notice, you will need to apply for retrospective approval by completing a regularisation application.
If you are registered disabled there is no fee to pay for either a Full Plans application or a Building Notice. Simply download and print the relevant form and ensure your registration number is included.
Building near to un-mapped public sewers
With effect from 1 October 2011, sections of sewer pipes or drains which are shared with another person’s property, or run through another person’s land and which have been privately owned were transferred by legislation to become “public sewers” which are owned and maintained by the sewerage companies.
The location of these newly adopted sewers will not be shown on the official “map of sewers” and their position in relation to proposed building projects will be largely unknown. Consequently, applicants will not be alerted of these sewers by the usual consultations with the sewer authority which take place when proposals are being considered for planning permission or Building Regulations purposes.
If you suspect your proposal may involve a public sewer in either of the following ways, you should consult with the relevant authority BEFORE commencing work to minimise any potential delays:
- Your proposal involves building over, or within 3 metres of, a public sewer, or
- You wish to make a connection to, or alter the pipework or access to, a public sewer
