The Best Security Decision Is the One Made Before an Incident
Every business owner and operations manager who has dealt with theft, a break-in, or an unsafe situation at their premises says the same thing afterwards: they wish they had acted sooner. The right security arrangement does not just respond to problems — it prevents them from occurring in the first place.
London Security Services (UK) Ltd provides SIA-licensed, professionally vetted security guards to businesses and organisations across London and the UK. We are available around the clock, we deploy quickly, and every solution we provide is built around your specific site, sector, and risk level.
Whether you need a single guard, a team of door supervisors, or a fully managed security solution across multiple locations, we will put together a deployment that fits your operation — not a pre-packaged arrangement designed to fit as many clients as possible.
What Our Customers Are Saying
London Security Services Limited has been at our various stores in Slough, Hounslow and Bracknell for over 3 years now and our stock losses dropped 95%. They have special tactics in retail security guarding and I am happy to have them supply us security personnel. 10/10.
Steve Caio
Regional Manager, Sports Direct
★★★★★
We have hundreds of thousands of pounds worth of high-risk construction equipment on our building site premises and have been attacked in the past before having London Security Services on board. Their mobile security patrols and static guards are exemplary and completely suit our requirements. I would recommend them to anyone who wants a security guard service in the London area.
John Todd
Site Manager, Borras Construction
★★★★★
London Security Services has been able to handle requests for coverage, even at the last minute. They provide professional security guards who go above and beyond to protect our property and employees. I would recommend London Security Services to anyone or any business experiencing security issues or concerns at their property.

Security Services Tailored to Your Business
The eight services below cover the most common requirements we encounter, but most clients we work with need a combination rather than a single category. If you are unsure what the right arrangement looks like for your business, get in touch and we will work it out with you.
Static Security Guarding
A visible, trained guard is one of the most effective deterrents available. Our SIA-licensed static guards protect your staff, assets, and property — and respond immediately when a situation demands it. If your site has already experienced incidents, or you simply cannot afford the consequences of one occurring, this is where to start.
Mobile Security Patrols
Unpredictable patrol visits carried out at varying times throughout the day or night. Every visit is logged and reported, and our guards maintain live contact with our 24/7 operations room. An effective and cost-efficient option for sites that need regular
deterrence without a full-time static presence.
Retail Security
A visible, trained guard is one of the most effective deterrents available. Our SIA-licensed static guards protect your staff, assets, and property — and respond immediately when a situation demands it. If your site has already experienced incidents, or you simply cannot afford the consequences of one occurring, this is where to start.
Construction Site Security
Plant, materials, and machinery left unprotected overnight are an open invitation. Our construction site guards understand the specific risks and compliance requirements of live building sites, and provide round-the-clock protection that keeps your project on schedule and your assets where they should be.
Door Supervision
Poorly managed venue access puts staff, customers, and your licence at risk. Our SIA-licensed door supervisors are approachable, professionally presented, and trained to manage access control, crowd situations, and conflict — so your team can focus on running the venue, not managing the door.
Event Security
Large or small, every event carries risk that standard staffing is not trained to manage. We provide experienced event security personnel who integrate with your planning and on-site team, manage crowd flow, and respond calmly and effectively to any incident that arises.
Corporate & Office Security
An unsecured office or corporate building creates risk for your staff, your data, and your assets. Our officers manage access control, provide a professional and reassuring presence, and carry out out-of-hours patrols — protecting your people and your premises without disrupting the working environment.
Key Holding & Alarm Response
An unsecured office or corporate building creates risk for your staff, your data, and your assets. Our officers manage access control, provide a professional and reassuring presence, and carry out out-of-hours patrols — protecting your people and your premises without disrupting the working environment.

Protection Through Excellence
Here is what we believe genuinely sets LSS apart from other security contractors operating in this market.
SIA Approved Contractor Status
ACS accreditation is awarded by the Security Industry Authority to contractors who meet the most rigorous standards in the industry. LSS holds this status — which means every guard we supply, every process we follow, and every deployment we make has been independently verified. It is the clearest proof that we are legitimate, compliant, and held to a higher standard than unaccredited providers.
A 24/7 Operations Room That Actually Answers
There is always a real person at the end of our line. Whether you have an urgent staffing request at 3am, an alarm activation on Christmas Day, or a situation developing at your premises right now, our operations room is staffed and ready to act.
Every Guard Vetted. Every Licence Checked
Before any guard steps on to your site, they have passed thorough background screening and hold a valid SIA licence. We do not supply personnel who cannot be fully verified. You receive a professional you can trust, and you can check their licence on the SIA register at any time.
Flexible Cover from Just 4 Hours
Our minimum deployment is 4 hours. That means professional, licensed cover for a short-notice event, a one-off requirement, or an urgent gap in your current arrangements — without being locked into a long-term contract you do not need.Transparent, Competitive Pricing
Our pricing is straightforward and matched to your specific deployment. You are not paying for a bloated package of services that do not apply to your business. We will give you a clear, itemised quote and explain exactly what is included before you commit to anything.Over a Decade of Proven Experience
Since 2014, we have protected businesses across London ranging from independent retailers to embassies, corporate offices to construction sites. That breadth of experience means we have encountered the situations other providers have not, and we know how to handle them.

Frequently Asked Questions
Are all your security guards SIA-licensed?
Yes. Every guard we deploy holds a current, valid SIA licence and has passed thorough background vetting before joining our team. You can verify any guard's
licence directly on the SIA register.
Do you only cover London?
No. We are based in London and the majority of our clients are across the
capital, but we provide professional security services throughout the UK. Contact us to confirm coverage
for your specific locations.
What is the minimum shift length?
Our minimum deployment is 4 hours. This gives you the flexibility to get professional, licensed cover for short-notice requirements without a long-term commitment.
How quickly can you deploy a guard?
In many cases, same-day or next-day. Our 24/7 operations room
handles urgent requests at any time. If you have an immediate need, call us directly on 0208 294 1444 and
we will work to get cover in place as quickly as possible.
What happens if a guard cannot make their shift?
Our 24/7 operations room monitors every deployment in real time. If a guard is unable to attend for any reason, we identify a replacement and notify you immediately. You are never left without cover and without communication. This is one of the most important commitments we make to every client.
Is there a contract commitment?
We offer both flexible short-term arrangements and longer-term managed contracts. We will recommend the right structure based on your needs — not on what ties you in for the longest period.
Do you offer a free assessment?
Yes. We are happy to discuss your requirements and provide a no-
obligation quote tailored to your site, sector, and risk profile.
