Only the best traders achieve our seal of approval.
For over fifty years, Which? has been the UK's leading expert in putting products and services to the test in ways that are truly rigorous and independent. And that's precisely the thinking that we've brought to helping you find a range of local traders you can rely on.

Every single trader appearing in this directory has been through our vetting process.
And that means

• They've been credit checked
• We've checked their qualifications and trade association memberships
• We've seen their customer list for the past year and taken references
• A Which? Trusted Trader assessor has visited them to judge everything from sales processes to the quality of their documentation to their complaints procedures
• They've signed up to our Which? Trusted Traders code of conduct

Clearly, not every trader will pass such stringent tests, but you can be sure that everyone who does, has our seal of approval.
