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 48 years on the register also points to an established business rather than a brand-new one.

Karnheath were a pleasure to deal with from the moment I contacted them. They kept in touch in a timely manner, carried out a proper survey and their work force were very helpful. They were on time, polite and tidied up after themselves. All areas of their company conducted themselves in a polite, considerate and professional manner. I can highly recommend Karnheath as a top quality business with the customer in mind.
Arranged visit for quote but had to cancel due to pregnancy issues. They were super flexible and came straight out once we were back in touch. Quote was good for loft insulation and they tested for cavity wall insulation which we had. Was able to get them in the next day to top up loft insulation due to a cancellation. Super appreciated the quickness with a 3 year old and new born in the house.
Excellent company to work with. From initial enquiry, quotation and work completion everything went smoothly. The guys were respectful of my property at all times. Thank you so much Micky and Neil for doing a great job of upgrading my loft insulation. Kath S. Ryton

Roofing isn't licensed, so anyone can set up - and it's a trade with more than its share of cowboys. A big re-roof must meet building regulations; CompetentRoofer (the Government-authorised NFRC scheme) registers roofers who can self-certify that, and vets and inspects them at least twice a year. Check they're on it before you hire.
Check the CompetentRoofer registerNever agree to roof work from a cold-caller at your door or an unsolicited 'we noticed your roof' note. That is the classic roofing scam.
Get a written quote that itemises access (scaffolding or a tower), the exact materials, and the workmanship guarantee, not a vague day rate.
Be wary of demands for a large cash deposit; agree staged payments against work you can actually see completed.
