Information and advice

What are Building Regulations?

Building Regulations are rules that ensure all new construction, conversions, alterations and extensions are built to a minimum standard and meet certain health, safety and welfare standards.

To demonstrate your work complies with the Building Regulations, you must submit a Building Control application, have the work checked and a completion certificate issued.

Do I need Building Regulations?

If you're a homeowner and planning an extension or conversion, you may need a Building Regulations inspection as well as planning permission. Whereas planning permission is about how a building looks, Building Regulations make sure your home is structurally safe and efficient. 

You may also need Building Regulations approval if you're planning to renovate your home. This includes changing internal structures, added new heating and hot water systems, toilets, electrics or windows.

Getting building work approved by Powys' expert Building Control team helps ensure that the work is safe and up to Building Regulations standards as well as protecting you against rogue builders. You should seek our advice before starting any building project - we can help you get it right first time, with minimal stress throughout your project, keeping it on track and saving you time and money.

Check if you need building regulation approval on the Planning Portal's Interactive House.

Your architect, if you have one, should be guiding through the construction process and requirements, and your builder should be competent and familiar with the Building Regulations.

Competent Person Scheme

Competent Person Schemes were introduced by the Government to allow individuals and enterprises to self-certify their work complies with the Building Regulations without having to submit a building notice and incur a charge.  These usually covers works such as electrical or gas installations, or replacing windows.

An installer registered with a Competent Person Scheme should notify the local authority of the work and issue you with a certificate of compliance under the Building Regulations either directly or through their scheme operator.

To find an installer registered with a Competent Person Scheme in your area or check that your chosen installer is with a scheme visit https://labcfrontdoor.co.uk/find-a-competent-person and enter your postcode or the name of the installer in the relevant search box.

Not Competent Persons Scheme Registered?

If you do not use an installer registered with a Competent Person Scheme you will need to submit a building notice and pay a fee so that we can arrange inspection of the work for you. See Apply for Building Regulations approval.

Projects exempt from the Building Regulations

Some building types and extensions are classed as exempt under the Building Regulations. This means an application does not need to be submitted to Building Control. The most common exemptions are detailed below.  They may still however need planning from Bannau Brycheiniog Planning Department or Powys County Council Planning Department

Conservatories

A conservatory built at ground level and less than 30m² in floor area and thermally separated from the existing house is normally exempt provided that glazing and any fixed electrical installations and heating installations comply with the applicable requirements of the Building Regulations.

Porches

Construction of a porch built at ground level of less than 30m² in floor area and thermally separated from the existing house, is normally exempt provided that the glazing and any fixed electrical installation comply with the requirements of the Building Regulations.

Sheds

Construction of a small detached building such as a garden shed or summerhouse in the garden will not normally require Building Regulations if the floor area of the building is less than 15m2. If the floor area is between 15-30m² you will not normally require Building Regulations providing that the building is either at least 1m from the boundary or it is constructed of substantially non-combustible material.

Garages

The construction of a new attached carport, open on at least two sides, would not normally require Building Regulations if it is less than 30m² in floor area. Construction of a non-combustible detached garage less than 30m² would not normally require Building Regulations approval as long as it doesn't contain sleeping accommodation. If the construction is of combustible materials the garage must be at least 1m from the property boundary.

Full details of all the exemptions can be found in  Schedule 2  of the Building Regulations.

If you are still unsure if your project is exempt please contact the Building Control team for advice. Email: buildingcontrol@powys.gov.uk 

The Party Wall Act

If you are proposing to start work covered by the Party Wall Act, as the homeowner, you must give adjoining owners notice of your intentions as set down in the act. Adjoining owners can agree or disagree with what is proposed and if they disagree, the act provides a mechanism for resolving disputes.

The act is separate from obtaining planning permission or Building Regulations approval.

Building Control has no involvement in the Party Wall Act
