Very pleased
Jordan came to replace a broken Chubb lock. Actually found JW on here, made an enquiry, response was prompt, booked in at a time that suited me and works carried out well, neatly and quickly with plenty of photos showing me what had been done as I wasn’t present. Very pleased and will keeping note of their details for next time and recommending on.Verified reviewerJob location: SW1110 Fire Doors Installation

JW Security was established in 1991 by Julian Whitter. The aim was to offer a professional and discreet service that home and business owners could trust in to protect their property.
Our service has proved a successful one and our company has grown over the last 20 years to provide an extensive range of locksmith and security related services to South London and Surrey.
We like to foster long term relationships with our customers, providing high quality services across multiple properties and businesses. Close to half our work comes from repeat business and good word of mouth.
JW Security is highly sensitive to customer needs and satisfaction and our whole team is professional and discreet. We have provided services to a number of high profile celebrities, government ministries, NHS services and high street banks who trust in us to get the job done properly and without any risk to privacy or internal security.
Everything we do is bespoke. No two jobs are ever the same, so every one of our projects starts out not just with a free estimate, but also a free security check and insurance schedule review to ensure you understand the complete security picture of your property or business.
