Hire a 鈥榗ompetent person鈥�

If your project needs approval but you鈥檇 rather not apply yourself, you can hire a tradesperson registered with a competent person scheme instead.

You must meet even if you do not need formal approval.

3. Use a competent person scheme

Competent person schemes are a way for tradespeople to prove their ability to carry out certain work to required standards, instead of you applying for building regulations approval.

Benefits of a registered tradesperson

An installer (for example of windows or boilers) who鈥檚 registered with a scheme can self-certify that their work complies with buildings standards and can deal with building control issues, like objections.

If needed, they鈥檒l tell your local authority about work on your behalf. They鈥檒l also give you a certificate within 8 weeks of completion which can be used as evidence of compliance - it will also show up in solicitors鈥� searches if you come to sell your home.

Competent person schemes have insurance-backed warranties and complaints procedures if there鈥檚 a problem with the work.

Search the to find a tradesperson, or check that they belong to a scheme.

4. How to apply

Contact a 鈥榖uilding control body鈥� (BCB) to check the building regulations or apply for approval.

There are different rules in and .

Where to apply

There are 2 types of BCB. It鈥檚 up to you which you use.

Local authority BCBs

You can .

Private BCBs

You can .

They鈥檒l tell your local authority about the work. This is called giving an 鈥榠nitial notice鈥�.

Choose a type of application

You must decide on the type of application for your planned build, extension or alteration work.

Full plans

This is the most thorough option. You can expect a decision within 5 weeks, or 2 months with your consent.

You鈥檒l get a completion certificate within 8 weeks of completion of the building work as long as it complies.

Building notice

This type of application is only for smaller projects. You can start work 2 days after your notice has been submitted to your BCB. You do not get formal approval like you do with full plans.

Regularisation

You can apply for 鈥榬egularisation鈥� - retrospective approval for work already carried out without consent - from a local authority BCB only.

Only work carried out after 11 November 1985 can be approved in this way.

You might need to make alterations before your BCB can agree the work complies and give you a regularisation certificate.

You may have to if building regulations are not followed.

Fees and costs

Local authority BCBs base their fees on the costs of their work, like site inspections.

What you鈥檒l pay depends on the:

  • type of work involved
  • number of dwellings in the building
  • total floor area, for example in the case of extensions

Private BCBs negotiate their fees directly with you.

You might not have to pay a fee for works carried out solely for a person with a disability.

5. Appeals and determinations

You can appeal if you think your project should not have to comply with building regulations.

Ask for a 鈥榙etermination鈥� if you鈥檙e refused building regulations approval and you think the building control body (BCB) decision is unfair.

If you think you should not have to comply

Ask your local authority to ignore or relax one or more of the building regulations if you think your project shouldn鈥檛 have to comply with them.

If the local authority still says you have to comply, you can appeal to government. You have a month to make the appeal.
