Which? Trusted Trader

Which? Trusted Traders is an endorsement scheme that recognises reputable traders who successfully pass their rigorous assessment process. Not just anyone can become endorsed. The assessment process involves:

  1. Credit Check

    A preliminary credit check to validate the financial health and stability of a sole trader / business.

  2. References

    Customer reference checks, chosen at random by a member of the Which? Trusted Traders endorsement team to ensure a breadth of consumers are consulted.

  3. Business Procedures

    A thorough examination of business and administrative procedures.

  4. Interview and Assessment

    We are visited in person by a Which? Trusted Traders assessor and interviewed.

  5. Code of Conduct

    The trader / business signing up to the scheme agrees to abide by the code of conduct and their terms and conditions.

  6. Endorsed Trader

    Once the trader / business  has passed the assessment process, only then will they be endorsed as a Which? Trusted Trader.

Conversion / Refurbishment

"It's hard to find a builder you can trust nowadays, so I was fortunate that Jack Koumis and his lads did my conversion. They worked to a high standard, were always courteous and never left me stranded by disappearing off-site like so many builders do!"

We anticipated the arrival of ‘the builders’ with some trepidation, especially on what was easily the largest building project we had undertaken but our anxieties were soon dispelled. Within a couple of weeks of the start of the project, Jack and his team seemed almost part of the family. Jack himself was very patient in answering our many questions and addressing our concerns and his team were on site every day and worked conscientiously and, considering what was being done, with less mess and disruption than we had feared. The work kept to Jack’s estimated timetable, the only delay being caused by our failure to have the necessary fittings/accessories on site on time, and we were satisfied with the quality and appearance of the end product.
