To ensure that your building works comply with building regulations and any other relevant legislation, we will carry out inspections during construction.

Following the submission of your application, you will be able to start your project after 48 hours. 

You must also notify us of your intention to commence by email to building.control@chorley.gov.uk at least 2 working days prior to your intention to start work and then notify us again within 5 working days of you physically commencing work.

Book an inspection

You can book an inspection by email to building.control@chorley.gov.uk. Alternatively, you can book an inspection by telephoning 01257 515162 during office hours (Monday to Friday 8:45am to 5pm).

24 hours notice is preferred to book an inspection but we will endeavour to carry out same day inspections dependant on workload and what time the inspection is requested.

Inspections required

An inspection framework must be agreed with your registered building inspector prior to commencement. The number and type of inspections that are required depend on the type of work. Minor works usually need fewer inspections than complicated projects.

The inspections may include:

  • at commencement of work
  • at excavation for foundations
  • prior to covering any reinforcing steel in foundations
  • prior to covering up any hardcore or damp-proof membrane or insulation
  • prior to covering drains
  • prior to plastering or encasing walls, beams, columns or ceilings
  • on final completion.

Most of the above refer to works that will be covered up but are not necessarily the only ones the inspector will inspect. Some projects require additional inspections specific to the work such as reinforcement of foundations and floor slabs, fire protection to the structure etc. We advise you inform your inspector prior to plastering to enable the work to be inspected before covering up (pre-plaster inspection).

When the work is completed let us know so we can carry out a completion inspection.

Providing the work is in accordance with the regulations a completion certificate will be issued. This is an important document to you as it provides evidence that your project complies with building regulations. It is also advisable to obtain the certificate before settling the final account with your builder. The certificate may be requested by a solicitor if you come to sell your property or wish to raise capital from your property at a later date.
