Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Highlights
“Matt fitted a replacement front door lock. He was professional, helpful and completed the job competently. He told me his eta and arrived on time. The work was done to the agreed schedule and budget. He also gave us some advice about maintenance. I would definitely use this company again/recommend them to others.”
“Booked an appointment at a convenient time and they called when on their way. Dismantled the various parts and explained the problem and what needed replacing. Ordered the relevant part and returned 3 days later to complete the job. Also solved a previous problem with the door lock! The engineer was efficient, polite and friendly and I couldn't have had a better service.”

Door Handle
Booked an appointment at a convenient time and they called when on their way. Dismantled the various parts and explained the problem and what needed replacing. Ordered the relevant part and returned 3 days later to complete the job. Also solved a previous problem with the door lock! The engineer was efficient, polite and friendly and I couldn't have had a better service.
Replacement window locks
Easy to contact. Charges were all explained to me in advance, and a call arranged for that day. Matthew arrived on time, replaced two window locks, and suggested a cost saving solution for a third window. He also freed up the mechanism on a patio door, that had become difficult to open. All done on the day. Friendly and helpful
Honest and Reliable Locksmith
Steve attended my newly purchased home for a change-out of locks. Very friendly, professional and punctual chap. A very honest locksmith too. Steve would offer pragmatic and cost efficient solutions. A highly commendable locksmith.

Endorsement Reference
The locking mechanism in our patio door seized and wouldn't lock. We were on our way out for the day when it happened so it looked like we wouldn't be able to leave the house. We found BM securities number on a leaflet. They arrived within an hour of us calling. They we very friendly and quickly found that the locking mechanism inside the locking strip had disintegrated. They couldn't get the key barrel out either so had to snap it to remove all the parts. They went and got the new parts and were back within a couple of hours. They fitted the new parts and adjusted the doors (They had become misaligned over time and probably contributed to the lock breaking) all in around 10 mins. The door now fits and locks perfectly. On the way out he kindly adjust my front door as well as this was also catching a bit.
Endorsement Reference
4 new door locks fitted. Steve very professional: detailed explanation of locks, completed job in good time, good timekeeping, polite, friendly, clean.

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