Slough is a working town. It has one of the busiest trading estates in the country, warehouses running all night towards Heathrow, and a town centre in the middle of a rebuild. As a security company in Slough, Alpha Security Services supplies manned guarding in Slough for sites that need an officer there every hour, and mobile patrols in Slough for sites that just need checking. Our security services in Slough are delivered by SIA-licensed security guards in Slough who are vetted, briefed on the site and matched to it before they start, and 98% of our clients stay with us.

Most of what we do here falls into three areas. Warehouse security in Slough is the biggest, because so much stock moves through Colnbrook, Poyle and the Trading Estate on its way to and from Heathrow. Then there are security patrols in Slough for smaller units and empty buildings that don’t justify a full-time guard. And there’s the town centre, where shops, offices and a large redevelopment all need different handling. When businesses hire security guards in Slough, they’re usually trying to fix a problem in one of those three places.
We’ve been running sites around the country since 2021. In Slough, our security officers cover gatehouses, loading bays, reception desks, building sites and shop floors. Every officer is briefed before the first shift, so you’re not paying for someone who spends the first week working out where the fire exits are.
A lot of our clients here run more than one site. A distribution unit in Colnbrook, an office on Bath Road, maybe a vacant building waiting to be relet. As a security guard company in Slough, we put all of them on one contract, with static guarding in Slough where it’s needed and patrols where it isn’t.
The useful part of the job is usually the boring part. A trailer left unhitched against a fence. A side door that hasn’t latched. A van that keeps circling the yard after hours. Our professional security guards in Slough are trained to notice that kind of thing early and deal with it, which is cheaper for you than finding out the morning after.
Our security guarding services in Slough, including the manned guarding services in Slough most of our clients start with, cover businesses, homes and the people inside them, from the town centre out to Langley, Cippenham and Colnbrook. Every officer holds the right SIA licence for the post and works to written assignment instructions for your site.












The short video shows how we run warehouses, gatehouses, shops and building sites. Door staff, static guards, key holding and patrols all report into one control room, so there’s one number to call whatever time it is.
Our bespoke security services in Slough are built around how each site runs: shift changes, delivery windows, cash handling, when the building is empty. We also provide residential security guards in Slough for homes and landlords, linked fire and intruder systems, and close protection for executives and VIPs visiting the area.
Offices on the Trading Estate and in the town centre need a slightly different setup. Security for offices in Slough is usually a reception officer in the day and a locked, checked building at night, and our security guard services in Slough can scale from one officer to a full team.
Whatever the site, security for businesses in Slough should stop problems before they cost money. That’s why our officers are there to prevent things, not just write them up.
You shouldn’t have to ring us to find out what’s happening. Our third-party guard management software shows live officer locations, rotas, duty coverage and every completed check, and you can assign a task from your phone.
Each officer has a body-worn camera, a radio and a reporting handset. GPS logs every patrol point, so security patrolling in Slough is recorded stop by stop across the Trading Estate, Colnbrook and the town centre. A missed checkpoint flags straight away, not at the end of the month.

A logistics yard and a hotel lobby need different people skills, and we train for both. A dispute at the gatehouse, an aggressive shoplifter, a 4am alarm: our officers are ready for all of it.
All of our officers are trained in Emergency First Aid at Work (EFAW) and fire safety. Our professional security services in Slough run to the same standard on every site, whether it’s a data centre gate on Bath Road or a shop on the High Street.

Running sites nationwide since 2021 has taught us how differently each sector needs protecting.
Industrial security in Slough is mostly about vehicles and paperwork. Retail is about people. Logistics is about the loading bay. We’ve built procedures for each, and as a manned guarding company in Slough we apply the right one to the right site.

Reliable cover starts with an officer who actually turns up. Our control room tracks every officer by GPS, and if nobody has signed on at your site when a shift starts, a replacement is sent from the local team.
Our alarm response in Slough gets an officer to you within 45 minutes of activation, and our key holding services in Slough mean nobody from your business has to drive in at 3am. Patrol vehicles use the M4, the A4 Bath Road and the A355 to keep travel times down.

“Alpha Security provides our first line of defense. Their gatehouse security team is the face of our industrial park, managing hundreds of HGVs and visitor vehicles daily. They are efficient, polite, and uncompromising on security protocols, keeping our traffic flowing while ensuring no unauthorized access.”
“Ensuring guest safety without compromising our welcoming atmosphere is a delicate balance. Alpha Security excels at hotel security. Their overnight team handles noise complaints and access control with incredible tact and diplomacy. Our staff feel safer, and our guests are completely undisturbed.”
“Our manufacturing plant operates 24/7, requiring constant vigilance. Alpha Security provides factory security that integrates seamlessly with our shift changes. They monitor heavy machinery areas, oversee contractor access, and conduct regular perimeter checks. Their professionalism and consistency are unmatched.”
We cover Slough and the SL1, SL2 and SL3 postcodes, plus the villages around the edge of the town. Our mobile patrol services in Slough move between the Trading Estate, Colnbrook and the town centre, so there’s usually a vehicle close by.
As a local security company in Slough, we keep SIA-licensed officers positioned around the area rather than sending them in from elsewhere. Having local security guards in Slough is how we cover sickness and short-notice requests without leaving a gap.
The redevelopment of the town centre and new building on the Trading Estate mean more construction and vacant property work here. Our 24/7 security guards in Slough cover all locations.



Most of them. We run 21 specialist security services and put together bespoke cover when a site doesn’t fit any of them.
Here’s the full range: security guards, door supervision, key holding and alarm response, vacant property security, construction security, factory security, warehouse security, logistics and distribution, gatehouse security, retail security, hotel security, pubs and clubs, the pharmaceutical sector, education security, student accommodation, entertainment and art, event security, corporate events, festivals and concerts, sporting events and weddings.
In Slough, most of our work is logistics and industrial sites on the Trading Estate and around Colnbrook, hotels along Bath Road, shops and offices in the town centre, and building sites. We also provide security for residential properties in Slough, from overnight patrols to a guard during building work.
It depends on what’s at risk and how often. A static guard makes sense for a busy gatehouse, a site with high-value stock or anywhere people need to be checked in and out. Mobile patrols in Slough suit units that are quiet overnight, buildings between tenants and sites where a visible check every few hours is enough to put people off.
Many clients use both: a static officer during trading hours, then patrols overnight. It’s usually cheaper than a guard around the clock, and we’ll tell you honestly if patrols would do the job. Our risk mitigation services in Slough can help you decide before you commit to anything.
The Trading Estate has around 30 data centres, with more being built, and they have very specific security needs. Most operators run their own technical security systems. Where they need SIA-licensed officers on the gatehouse, the perimeter or reception, we can supply them, along with security for construction sites in Slough while new data halls are being built.
The same estate is home to offices, factories and distribution units, and security for commercial properties in Slough there usually comes down to gate control, vehicle checks and night patrols. Perimeter security in Slough units is checked on every round, with fences, gates and lighting all tested.
Warehouses around Colnbrook and Poyle often handle air freight and high-value goods, and they rarely close. Our officers control the gatehouse, check drivers and paperwork, match trailer seals and patrol the yard between loads. Most losses happen at the loading bay, not through a broken window, so that’s where we concentrate.
Quieter warehouses can switch to static cover in the day and security patrols in Slough at night. If a unit is empty between tenants, vacant property security in Slough keeps insurers happy, with internal inspections and a photo report after every visit.
Give us 24 to 48 hours from agreeing the site plan and planned cover is in place. Call in the morning and we can often have someone there the same day. Emergency cover after a break-in or a no-show arrives within 2 to 4 hours.
You don’t have to sign a long contract to hire security guards in Slough. A single shift, a few busy weeks or an ongoing contract are all fine, and we’ll adjust cover as your needs change. Ring, email or fill in the form, and you’ll get an email reply within 4 working hours.
A marked vehicle arrives at a time agreed with you, but never at the same time two nights in a row. On arrival the officer works round the building: doors, shutters, fences, lights. If your contract includes internal checks they go inside too, and each stop gets a GPS scan so the visit is on record.
Anything unusual is photographed and reported straight away. If something serious is found, the officer stays on site and calls the right people. Private property security in Slough for homeowners away for a few weeks works the same way, with property security in Slough checks timed around when the house is empty.
It might. Queensmere shopping centre closed in January 2026, with demolition due to start in winter 2026 as Berkeley builds up to 1,600 homes over the coming years. The Observatory is still trading. Long building projects bring hoardings, changing footfall and empty units, all of which can move problems onto neighbouring streets.
If your business is near the work, it’s worth reviewing cover. Business security in Slough around the redevelopment often means extra checks on rear access and service yards, and construction site security in Slough for contractors on the scheme itself.
Our control room receives the activation and sends an officer with your keys, who reaches you within 45 minutes. They check the building inside and out and report back with photos.
If there’s been a break-in, the officer calls Thames Valley Police, leaves the scene as it is for evidence and stays until the building is secure or you arrive. Keys are kept in a monitored facility under a code, not your address, and every use is logged.
Talk to the council early. Slough Borough Council’s Safety Advisory Group brings together Thames Valley Police, South Central Ambulance Service, Royal Berkshire Fire and Rescue Service and council teams including licensing and highways, and organisers can contact it through events@slough.gov.uk. If no more than 499 people will be there at once, a Temporary Event Notice can cover the licensing.
We’ll size the security and stewarding team to the plan you agree with them. Event security in Slough can be two officers at a private function or a full team at an outdoor event, and our event security guards in Slough work alongside your own staff on the day.
A supervisor visits each site on a regular schedule and fixes problems on the spot. GPS check-ins, timestamped reports and checkpoint scans show whether patrols were completed, without relying on anyone to own up.
We also track alarm response against our 45-minute target and check that incident reports are good enough to use. At review meetings you see commercial security in Slough reported site by site, and lessons from one contract are shared across our community security services in Slough and commercial work.
