After a worrying email I received from a local resident (who was keen to help others) can I encourage constituents who require the services of a locksmith to be aware of the Master Locksmiths Association’s (MLA) advice on how to spot a “rogue locksmith”: https://www.locksmiths.co.uk/faq/how-to-spot-rogue-locksmith/
The MLA also has a database of “MLA approved” locksmiths – more information can be found here: https://www.locksmiths.co.uk/
