“We have just had all our windows replaced by Unique Windows and couldn’t be more happier. The fitters (Clint and Matt) were courteous, tidy and just very pleasant from the time they arrived (which was early) until they left, everything was smooth and professional. We would have no hesitation in recommending Unique Windows. Thank you very much for a great service.”

Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 20 years on the register also points to an established business rather than a brand-new one.
