What makes selecting TrustMark tradesmen so worthwhile?
A firm's technical skills have been independently checked through regular on-site inspections, as well as checks on their trading recordand financial status;
Firms have signed up to a code of practice that includes insurance, good health and safety practices and customer care;
The approved scheme operator has checked and will continue to monitor the firm's quality of work, trading practices and customer satisfaction;
Firms are able to offer an Insurance Backed Warranty;
Deposit Protection Insurance is available for consumers in the event a firm should cease trading;
Firms will be able to tell you about any building regulations you must comply with and may also be able to provide appropriate certificates;
If you have a problem or disagreement with the firm, there will be a clear and user-friendly complaints procedure to help resolve the issue;
The scheme is fully supported by Government, the building industry and consumer protection groups.
All of these checks will give you - Peace of Mind
If a firm displays our TrustMark logo you know that we have approved and inspected the firm through one of our scheme operators and found that the firm meets the required Government endorsed criteria as described above. Find out more on how to avoid rogue traders.
Important Note:
When employing a TrustMark tradesman always check they are 'licensed' for all the trades / work you are asking them to carry out. This can be done by looking on our website by searching under the 'trade' then 'their company name' and finally 'more information' - you will then see a list of the 'only' trades that the firm is licensed for under the protection and standards offered by TrustMark.
