About Costello Security

Costello Security has provided a premium manufacturing and security service for many years to both residential and commercial customers.

We are a customer focused company that enjoys success in a competitive security market by giving our customers that little bit extra. This includes:

  • Free no obligation surveys
  • Rapid supply and fit service
  • High quality products
  • Expert installation by our own staff
  • Free help and advice from experts who know what they are doing
  • Competitive prices

These clearly defined policies enable us to be more competitive, give a greater standard of care both during and after installation and ultimately ensure our customers’ total satisfaction.

Most of our work comes by recommendation, so we know that what we do works. If you have any security requirements or need a fast and reliable locksmith - call us today. We will arrange an appointment if it’s a security installation enquiry, or send an engineer if it's an emergency within an hour!


With our local offices based in Banstead and Central London, we are perfectly placed to provide our high quality security installation, maintenance and repair service to customers throughout the London boroughs, home counties and across the South East.
