Check your tradesmen

We know you're busy. And checking a tradesman sounds like a chore. But do you really know a decent builder from a dodgy one without checking?

Find local Trades people for small jobs

Don’t part with your hard earned cash on false pretences or risk shoddy workmanship. The best way to check that your tradesman is legitimate is to check their Trade Association, a good indication of their qualifications and professionalism.

Use our Find a Local Tradesman service to help you with your building projects

You should check they are who they say they are:

1. Ask your tradesman what association they belong to

2. Call the association and ask if your tradesman is a member. If the association has an online search function, we have directly linked to it below. Be aware that these links sometimes change and can become outdated

TrustMark registered

If your builder says he/she is a member of TrustMark, check the online register to see if they are a member. If a firm is TrustMark registered, it is working to a code of practice aimed at giving you greater confidence and protection.

General Builder Trade Associations

National Federation of Builders
NFB members are “strictly vetted and have undergone a range of reference checks, safeguarding and giving you peace of mind”. Their search function allows you to check or find an NFB builder in your area or by company name.

Federation of Master Builders
FMB have “thousands of vetted members”, although check their membership criteria as there are different levels of criteria and checks for different types of members. You can find or check your FMB registered tradesperson is legitimate.

Electricians, Plumbers and Heating Engineers Trade Associations

This is the main trade association for electricians who are “assessed regularly to ensure they are meeting standards by checking their work, premises, documentation, equipment and competence of their key staff”.

Contractors registered to the NICEIC Building Regulations Schemes are authorised to self certify their work without actively involving the Local Authority.

The website allows you to find registered electricians in your area. You can also check your contractor is registered by entering their registered Company name. Check out members.

NAPIT – The National Association of Professional Inspectors and Testers
NAPIT is a Government approved Competent Person Scheme committed to setting the standard for industry. Members are regularly inspected to ensure that these standards are met. The NAPIT website lets you identify local and reputable trades people including plumbers, electricians, heating and ventilation contractors.

Association of Plumbing and Heating Contractors
APHC members sign up to a customer charter and members who self certify work have annual on-site assessments. Their website’s search engine allows you to search by postcode, town, type of work or business name.

Gas Safe Register
This is the official list of gas engineers who are registered to work safely and legally on boilers, cookers, fires and all other gas appliances.  Members undergo regular inspections. Anyone dealing with gas should be registered with this Trade Association, which was formally known as CORGI. Search members.

Architects Registration Board
The ARB is set up by Parliament as the independent UK regulator of architects and only people on the register can describe themselves as an architect. The site has a good search function.

Royal Institute of British Architects
RIBA Chartered Practices must meet their  “world leading standards of professional practice in quality, customer services and insurance.”  You can check that your architect is a member.

But Beware – some Trade Associations are better than others….

Trade Association membership is a good indication that your tradesman is professional – and especially important if it means the tradesmen can sign off their work as Building Regulation compliant. This is important when you sell your home and you will need to produce certificates to prove that your work meets the national building regulation standards. It sounds dull, but building regulations are the law.

While a Trade Association membership can’t ensure work will be perfect every time, you should be able to expect any problems will be dealt with fairly, and you can turn to their Association for help with any unresolved issues and complaints.

To qualify, Trade Associations may ask tradesmen to meet certain criteria and demonstrate high quality standards. It is a good first port of call – but take note: these organisations are funded by membership fees. They will have varying levels of checks, and striking someone off their list will mean a loss of income. So while they offer some protection you can’t take them at face value. If you want to compare and contrast then look at their codes of practice to see how much protection they give you.

My Tradesman isn’t a member of a Trade Association. Are there other checks I can do?

Yes. See our guide Top tips for finding a trusted tradesman for more details.
