• Hi - Let me introduce myself

    My name is Ed and with help from my extremely supportive family, I run Cerberus Security.
    When I started the firm more than a decade ago, I promised myself I would never compromise my morals and would do my best to save my client money wherever I can.
    To this day I believe I have upheld my promise and although a business needs to make money, people deserve to pay a fair price for the job that needs doing and no more.
    You will often find my wife Laura accompanying me on most of my call outs as she suffers from several long term medical conditions so I am her carer. She's a little soldier and usually has a big smile on her face, especially if she has a nice cup of coffee (hint hint).

  • Ed started the company in 2007 and since then has worked tirelessly to offer a friendly and honest service even at the cost of profit. Our overall total job costs are significantly lower than the majority of our competitors and we guarantee you'll not a more personal friendly service!

    We are physically located in Sawston South Cambridge and are not a call centre 200 miles away claiming to be local! Do not be fooled by these pretenders. Some of these firms do not even have a single locksmith in their employ. What they do is promise you an engineer within the hour and then start calling locksmiths in your area such as ourselves asking us to cover the job for them. If they cannot find someone they will wait for you to call asking where is your engineer and then make some excuse (his vans broken down being a favourite) at which time it may be too late to find another.
