These credentials and memberships are attributed to named public sources. Check the source before relying on them.
Locksmith Services Ltd is linked to a Companies House entry. This shows the business registration, not evidence of workmanship or service quality.
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 17 years on the register also points to an established business rather than a brand-new one.

“Steve turned up on time and put shoe protectors on immediately. He devoted a lot of care to re-aligning the door, he clearly likes his work. I would have no hesitation in recommending him.”
“AHL Locksmiths in Isleworth has replaced faulty locks in my home over past several years. He is very knowledgeable with regards to locks, arrives punctually and is a very interesting person to chat with. His charges are reasonable & I would highly recommend him to fix your lock problems.”
“Lucian was brilliant! He was punctual and arrived within an hour - 8pm. He was able to supply and fit a new front door lock, a part he was carrying in his van and ensure we were safe. Whilst here he checked all our external locks. Lucian was incredibly thorough and extremely helpful, we could not recommend him too highly. His charges were very reasonable.”

Dean arrived on the dot of the appointment time with the replacement lock for our back door (pre-ordered by his father from an inspection a few days earlier) and fitted it expertly.

We had been struggling with a bifold lock for a while when we called Dean and Larry for help. Dean attended the day after our call and was punctual and professional throughout.

First Class Service
The lock on our back door had broken and I was also beginning to find the front door lock stiff and difficult. After a helpful phone call with Larry, Dean arrived and efficiently diagnosed the problems. He replaced a mechanism in the back door and made adjustments to the front door. He explained things, advised on future maintenance and checked before leaving that I could easily manage both doors. A professional and friendly service, we are pleased to recommend.

Excellent Service in Replacing Door Lock
The lock on our extension UPVC door had become stuck in the locked position. Found Locksmith Services in a local Hemel magazine and contacted them by email with photos, requesting a non urgent visit and the likely cost. Dean replied immediately quoting their labour charge and the possible parts required. He attended two days later, replaced the faulty lock cylinder, advised on future care of the door mechanism, and even checked and adjusted another UPVC door which was out of alignment for no extra charge. Dean's invoice was completely as described and estimated and was very good value. Dean was extremely professional,efficient, polite and friendly in performing this work and we highly recommend Locksmith Services Ltd.

Our front door locking mechanism was becoming loose and worried it would fail. Contacted Locksmith Services as they had been recommended on our local Facebook page. Email response very quickly requesting photo of the lock and were quoted for the replacement. Dean arrived the following day and replaced the handles and also gave us very helpful advice on obtaining some more spare keys. Invoice matched estimate. Would highly recommend.

Friendly, efficient family-run business
Used LS Ltd for the first time to sort the front door of my elderly mothers flat, when a key had snapped in the lock preventing access. Larry turned up very swiftly, outside working hours, and sorted the problem quickly and efficiently. Will certainly use them again. Highly recommended.

Replaced failed night latch
Night-latch on front door failed so not able to open. Made contact via e-mail over the weekend and was happy to wait until the Monday as not an emergency. Had a call from Dean on the Monday morning who visited that afternoon, took the old latch off and replaced it with a new one. Very efficient, courteous and professional.
Work completed:
Excellent response and customer service
Called Larry for issue with front door latch and he came to our rescue the same day and Dean followed up for part 2 later that day. Great team and impressive knowledge and advice. Something which could have been a headache for us was resolved quickly and expertly by them. Great communication and follow through of actions. Thank you both so much.

Excellent service
Dean was excellent. He arrived quickly to fix a lock on bi-fold doors. Offered advice on the parts needed and completed the job promptly and efficiently and when he said he would. I can’t recommend Locksmith Services Ltd highly enough.
