The main purpose of the Building Regulations is to:
- secure reasonable standards of health and safety for persons in or about buildings
- energy conservation
- access and facilities for people with disabilities
Planning Permission and Building Regulations are two different things.
Building work needing approval
In general, most building work requires Building Regulations approval, including:
- erection of a new building, re-erection of an existing building or change of use of a building
- extension or alteration of a building, including loft conversions and garages
- installation, alteration or extension of a controlled service or fittings to a building
- replacement of window(s) / door(s)
- internal structural alterations, such as the removal of a load-bearing wall or partition;
- installation of certain heat producing appliances;
- underpinning of foundations
- installation and alterations of most electrical circuits within dwellings; and
- alterations and refurbishments of certain “thermal elements” and services.
Acceptable safety levels and construction standards are set out as guidance within booklets referred to as Approved Documents.

Extending your home
The Building Control Department at Cyngor Gwynedd have created an information booklet regarding extending a domestic property.
When building work starts on the site
The Council’s Building Control Surveyor will need to inspect the work on the site regularly to ensure that all the building standards are met.
It is important that the builder or owner notifies the Building Surveyor at certain stages of the building work. Contact us to arrange a site visit.
Anyone intending to carry out demolition work within the area is required to notify Gwynedd Council.
Certain conditions may be specified relating to the site safety and the manner in which the work is undertaken.
Once building work has been completed in accordance with Building Regulations and your Building Control Surveyor is satisfied that all the appropriate inspections have been carried out, a Completion Certificate can be issued.
This certificate is your assurance that the work has been inspected by a qualified Building Control Surveyor and as far as can be reasonably ascertained complies with the appropriate Building Regulations.
Health and safety
If you are carrying out building or renovation work it is also possible that you will need to inform the Health and Safety Executive as there is a possibility you have additional responsibilities.
For further information visit the Health and Safety Executive website.
Every building contains radon but the levels are usually low. The chances of a higher level depend on the type of ground. Public Health England has published a map showing where high levels are more likely in England and Wales.
