About Coverguard security

Experienced, Dedicated & Reliable


At Coverguard, we are dedicated to providing peace of mind through the provision of security services for both businesses and private individuals in the Thames Valley area.

We like to work in partnership with our clients and provide the best, cost-effective solution for their requirements.


By having a friendly but efficient approach, we aim to build mutually beneficial and long-term relationships with our clients.


A family run company, Coverguard, has bases in Windsor and Milton Keynes, and was established in 2000.

From our Windsor office we provide a wide range of security services to private individuals and companies along the Thames Valley area / M4 corridor, including Ascot, Bracknell, Bray, High Wycombe, Maidenhead, Newbury, Reading, Slough and Windsor.

From our Milton Keynes base, we cover the Aylesbury, Bletchley, Buckingham, Milton Keynes, Newport Pagnell, Olney, Towcester and Woburn areas.

Our services include Alarm Response, CCTV, Close Protection, Event Security, Intruder Alarms, Key Holding, Mobile Visits, Security Guards and Surveillance to mention just a few.

As the first security company to achieve ISO9001:2015 certification, Coverguard Security are also an SIA Approved Contractor, achieving within the top 25% for our sector. Being ACS Approved means you can feel confident in the knowledge that we are a cut above the rest. We do things right the first time and are very proud of our high standards.

If you are unsure which service will best suit your needs, we can carry out a site survey to ascertain if your premises or site has any security weaknesses. Any advice given will be impartial and we will make recommendations according to your business requirements and of course, your budget!

Our security professionals have the right corporate experience and maintain the highest levels of confidentiality and discretion. We can assist any industry, in national and international locations, at Corporate and Government sites, as well as private homes.

At Coverguard, we believe in building strong mutually beneficial relationships with our clients and work hard to not only meet, but exceed expectations and at competitive prices. More often than not, we are awarded contracts because we provide value for money, we’re friendly and approachable and have the client’s best interests at heart.

We only employ people with the right attitude and who can show discretion and common sense. Only those who can use discretion and think on their feet in any situation are chosen for your requirements. Most of our people work personally with the Managing Director in some capacity, to see first hand how they perform. How many other security companies can say that?

So before you turn to the large corporates for your security needs, give us a call first!

SIA Licenses

It’s been a while since I wrote my last blog post. With Covid-19 doing the rounds, coupled with the standard busy-ness of a security company, it has been a busy time. We all know that renewing our SIA license can be a drama, so I wasn’t surprised when a friend got in touch and asked for help with the issues he was facing. Read all about “Rob’s” story here.

Support our Police!

We all know that Brexit is and will have a significant upon the UK: whether that impact is positive or negative is a matter of huge debate from both sides. One thing that is promised though, is the money we are paying for EU membership will be spent on our services such as the NHS, police, schools etc, writes Paula Mathers, Assistant Director at Coverguard, the SIA approved contractor.
