Working with a Trust Mark Accredited Company

An image of green tick.

Here at Williams Windows DG Limited, we have earned a wide variety of accreditations over the years, demonstrating our commitment to delivering excellent customer service. In our latest post, we explain our Trust Mark accreditation and why it’s important to work with a company that displays this logo.

What is Trust Mark?

Trust Mark is a government endorsed quality scheme which covers any work that a consumer chooses to have carried out in or around their home. There are multiple benefits to both the consumer and business of having a Trust Mark accreditation, so let’s discuss them.

The Benefits of Trust Mark

As a consumer, working with a Trust Mark accredited company can provide you with the peace of mind that you will be working with a team that is both reliable and honest. In the day and age when there are many rogue traders attempting to undermine the work of trusted companies, this symbol can help you, as a consumer, narrow down your choices if you’re unsure of which trader to choose.

When a company is genuinely Trust Mark accredited, as a consumer, you can request quotes directly from an online consumer portal. The secure and free online portal will allow you to track every stage of your quote, keeping communication between you and the trader as clear as possible.

Should you have a complaint about the service you receive from a Trust Mark company, you will be protected by the Trust Mark network of Scheme Providers and Trading Standards in integration, giving you total peace of mind.
