What Our Customers Say

"I’d like to send a customer satisfaction testimonial for Michael Pearson from William Channon, who has recently completed some works at the Halls of Residence I work at. I can’t praise him enough. It was a very tight deadline which I required the works to be completed and there was a lot to do, especially on his own, but he got everything done without any issues. The communication was great, and he always kept me informed in regards of how many keys he could provide me with immediately, and how many were left to follow on. Nothing was too much trouble and all done with a smile on his face. Good customer service is rare these days, so when someone goes above and beyond."

Natasha Bradshaw - Accommodation Advisor, University College London

"I would like to send a big thank you to Miguel and the locksmith team for getting us out of a massive hole last week. We found out on Tuesday that we had a number of moves taking place which we had not been made aware of and I needed multiple keys by Thursday lunchtime. I am aware that they were short staffed but they fulfilled my order. Can you please extend to the whole team that I am indebted to them and very grateful. As always, excellent service."

J Savage - King's College London

"We had a complicated site in London for which we wanted a Masterkey solution. After discussing the project with a number of companies, Jim Caldwell of William Channon was the only person who seemed to understand exactly what we needed. After a very helpful site visit, all items were provided on time in stages as required and the fitting work was finished off by Oliver in a very professional style. Everything went smoothly and a solution was found for every problem. I would recommend William Channon for those needing a professional locksmith service and I would certainly go back to them again with future projects."

Louise - London SE1

"We approached William Channon earlier this year for advice as we were looking for ways to make the management of our student lockers more efficient. We were delighted that Terry was able to design a bespoke solution and to complete all the work needed to convert the lockers within a very limited timeframe during the summer vacation. The service we received was personal, professional and highly skilled and my team and I are incredibly grateful."

Gaynor Jones - Head of MBBS Management, UCL

"I could not be more pleased with the advice and service I have received from William Channon. From initial telephone contact, through survey, quotation and then installation, I have been impressed with the response and solutions to my awkward locks/keys/security issues. I can recommend it as a thoroughly professional company and one that has been a pleasure and relief to find and deal with."

Neil Thomas - Chairman of Falconbury Ltd

"...thank you very much for your help, we really appreciate it, you made this process so simple for us, it is lovely to experience such wonderful customer service."

Anna - London NW2

"Thank you so very much to you and Terry for giving me a wonderful service on ordering two very large chubb safes. I have never had to organise such a large project on this scale, where safes are concerned, and your company gave me the 100% commitment that I was looking for. I look forward to working with again."

Jane Berko - Jane Berko Designs

"This is firstly, to say how grateful I am to Roberto Giorgio for opening the door today. (Three of us couldn't do it!) Also, to say thank you to him for the skill and workmanship with which he repositioned the locks. Despite the warped door, the keys now glide into the locks and I can open the door with the touch of a finger. And...he swept up afterwards and made sure that I could use the keys easily."

J Birch - London

Frequently Asked Questions

What locks should I have on my front door?<br />

Your insurance company will usually confirm their security requirements, to you. Locks should be certified to British Standard BS 3621, BS 8621 or BS 10621 and will display the BSI Kite Mark and relevant standard. Locks for PVC-U and composite doors (when multi-point) should meet the minimum requirement set out in PAS 3621, PAS 8621 and PAS 10621.

Lock cylinders should meet the requirements of BS EN 1303:2015 Key related security Grade 5 and Attack resistance Grade 2. Technical specifications SS 312 and TS 007 are to be used when doors are at risk of cylinder attack and may be a requirement by some authorities. Cylinders that are Sold Secure Diamond rated have been subject to an extensive attack test and offer a significant security upgrade to any door that requires a Euro cylinder. We recommend that for retro fit security upgrades, SS312

Diamond cylinders should be used as a cylinder change only solution or a TS 007 one star rated cylinder combined with a two star rated handle or a TS 007 three star rated cylinder (either TS 007 solution must achieve a total of three stars to be effective against attack).

Is there a risk to lost keys at my workplace?

Lost keys present a significant risk to the security of the building, it’s occupants and their contents. Where a mechanical locking system is installed we advise that you change the lock for new, with a different set of keys. If master or sub-master keys have been mislaid you should replace the locks under it’s control – this may result is a completely new master key system being installed..

In cases of regular losses, you should consider an electromechanical or digital cylinder system. These systems allow electronic master-keying and reprogramming, and the immediate removal of any key that is lost, mislaid or stolen. The security of your building and it’s occupants is protected.
