10 Highly reccomend.
Posted 16 December 2025
Lawrence, you were super, super helpful to my 90 year old dad. You sorted out his lock and took time to make sure that he was happy with it. You also carried out a totally unrelated odd job for him without even a blink!! I absolutely would recommend Lawrence and if I have a need for a locksmith again, I will be looking him up. Thank you so much! You're an absolute gentleman!Verified reviewerJob location: W7Response from Certified Locksmith
