APHC

Plumbing and water · Trade association and separate certification schemes

The Association of Plumbing and Heating Contractors supports plumbing and heating businesses. Its licensed membership and its certification services are distinct: a business may need more than one approval for its work.

What it covers and whether it is required

APHC provides a trade membership route and operates competent person and MCS schemes. Membership is voluntary; specific gas work, water fittings duties and Building Regulations requirements still apply independently.

Joining requirements and costs

APHC checks technical competence and requires the documents and certificates listed on its application. Licensed members commit to its Customer Charter. Apply separately for any certification scope required, rather than assuming association membership includes all self-certification or renewable installation permissions.

Check the current fees with APHC before applying. Ask whether the quotation includes application, assessment, renewal and any per-job charges. Use published fees or ask for a written quotation.

What it means for homeowners

The APHC search distinguishes membership and specialist activities. Its own guidance says customers may wish to carry out additional checks. Confirm registration scope, the proposed compliance certificates and any guarantee before agreeing a plumbing or heating contract.

How to check a claim

Official member, card or certificate check: APHC.

Match the record to the named person or contracting business. Check the current scope, not just a logo on a van or an old certificate. If the public record does not show the detail you need, ask the body to confirm it before appointing the business.

Where the scheme applies

UK plumbing and heating businesses. Competent person self-certification depends on the scheme’s authorised territory and work scope; it is not a universal UK notification system.

Common questions

Is APHC membership the same as Gas Safe registration?

No. An APHC member doing regulated gas work must hold the appropriate Gas Safe registration as well.

How do I check APHC status?

Use the official verification service linked in this guide. Match the person or legal business name, current status and relevant work category. For a guarantee, check the document issued for your contract as well.
