Business Security London

Reliable, on-the-go security for business owners


We can recommend the very best system to suit your business requirements

For a security system to be absolutely reliable there can be no blind spots or loopholes. We don’t believe that can be achieved from off-the-peg solutions. Instead, we begin with a FREE site survey by a business security expert, who will then design a system specifically for your needs and budget.


We install the latest commercial intruder alarm systems, backed up with monitoring and maintenance services to keep you, your staff and your premises safe at all times.


CCTV provides a very effective defence against intruders, acting both as a visual deterrent and an important resource to support prosecutions following damage or theft.


With the installation of an access control system from Spy Alarms, you can easily control who comes onto your premises, both during and outside office hours.


We have been working with businesses of all sizes for over 30 years and have a reputation for designing, supplying and installing high quality, bespoke fire alarms.


Having someone you can rely on constantly monitoring your alarms ensures that your security system does the job it’s there to do, even when there’s nobody around.


Regular maintenance ensures that any potential malfunctions are spotted before they compromise your security and that your business protection remains fully functioning.


We are NSI Gold accredited – the highest level in our industry

We are also proud to be BAFE accredited to SP203-1

Our accreditations are proof that we work to a set of extremely high standards and are audited on a six monthly basis to ensure that we are maintaining them. NSI Gold is recognised by the police and all insurance companies, so it is valuable in qualifying customers for police monitoring and helps to secure the most favourable insurance premiums.

We are proud of our service and dedication to excellence

For a security system to be absolutely reliable there can be no blind spots or loopholes. We don’t believe that this can be achieved from off-the-peg solutions. Our security systems are tailored to you.

All solutions start with a FREE site survey

We begin every enquiry with a FREE site survey by a business security expert, who will then identify weaknesses and design a system specifically for your business needs and budget.

Our surveyors leave no stone unturned

Does your workplace have specific areas of vulnerability, such as a first floor flat roof or a concealed rear entrance? Is it compliant with the latest fire safety regulations? We’ll make sure you’re protected.

We provide complete, solution-based service

We take all factors into account when recommending the best system for your small or established business, as well as considering the integration of different systems, e.g. a smoke alarm installed in tandem with an intruder alarm.

Why do I need a survey?

We believe the more tailored and complete a service we’re able to provide, the more secure and confident our customers feel with their new system installed.

Having worked closely with Spy Alarms over the last two years on several refurbishment projects, we can say with confidence that they are a professional, helpful and efficient security company. Swift to react to call-outs, knowledgeable about industry products, and pro-active in finding bespoke solutions for our travel centres across London, we highly recommend them.
