Why Choose A TrustMark Tradesman?
All TrustMark traders work to a code of practice set down by an approved Scheme Operator to give you greater confidence and protection. Registered firms are checked and monitored against recognised British and International industry standards which means you have peace of mind that you are dealing with a professional organisation.
Checked and Vetted
Before a company is even accredited with the TrustMark logo, they go through a series of stringent checks. Their record and financial position are investigated and once accepted, they continue to be independently checked through regular on-site inspections. This is to ensure that all members continue to meet a high standard of workmanship, quality and service.
Code of Practice
When companies sign up to TrustMark they must agree to work to a code of practice that includes insurance, good health and safety practices as well as customer care. The approved scheme operator will continue to monitor a member’s quality of work, trading practices and customer satisfaction for as long as they are a member of the organisation.
Avoid Rogue Tradesmen
If a double glazing company displays the TrustMark logo you know that they have been approved and inspected through a scheme operator. All accredited companies as part of the scheme are required to meet current UK Building Regulations.
Insurance Backed Warranty
All company members must also offer consumers an insurance backed guarantee or warranty. This is extremely important since this insurance policy covers you against certain problems if the firm should ever go out of business.
Each accredited company will offer a different warranty (depending on the product and type of installation) through their chosen scheme operator but TrustMark dictates that the warranty must at least cover the following points:
- Quality of Workmanship
- Rectification of defects or major damage
- Non-compliance with Building Regulations
The warranty offered must be designed for the individual home owner and it is a requirement that it covers most jobs between £500 and £50,000. The duration of the insurance cover must be a minimum of two years – longer subject to trade.
Deposit Protection Insurance
All TrustMark Tradesmen must offer some form of deposit protection insurance for their customers. This is to ensure consumers are protected in case of a company ceasing to trade.
The TrustMark scheme is fully supported by the Government, the building industry and consume protection groups so you can have complete peace of mind whenever you choose one of their accredited installers.
