Looking for a security company in Colchester that can put a guard on a shop door in the city centre on Saturday and run mobile patrols round a Severalls unit every night of the week? That’s what we do. Alpha Security Services provides security services in Colchester for shops, offices, industrial estates, venues, and student blocks, with manned guarding, mobile patrols, and SIA-licensed security guards who are vetted and briefed before they ever set foot on site. 98 out of every 100 clients renew. Call 023 8111 2814, and we’ll come and walk the site with you.

Colchester’s a big place to cover, and the risks shift depending on where you are. Essex Police currently list Stanway, the city centre, the retail areas and Castle Park as hotspots for anti-social behaviour, theft and violence. Vehicle crime clusters around New Town, Christ Church and Greenstead. The night-time economy in Castle ward is a priority for serious violence and drugs. And burglary turns up everywhere from the suburbs to the rural edges.
So we don’t send the same officer to every job. We’ve been running sites nationwide since 2021, and the security officers in Colchester we deploy are picked for the post, and our security guard services in Colchester are priced around it: a shop floor on the High Street, a gatehouse at Severalls, a night patrol round three units in Stanway.
Lots of local firms have more than one site, and a single security guard company in Colchester makes life simpler. A shop in Culver Square, a unit at Whitehall Industrial Estate, a block of flats in Greenstead. As a security guard company in Colchester, we’ll put it all on one contract, using static guarding in Colchester where someone needs to be on site all shift and mobile security patrols in Colchester where they don’t.
Most of what we stop is spotted early. A van parked by a loading bay for far too long. A side gate left unlocked after the last delivery. The same group drifting back to one doorway in Castle Park every evening. Our local security guards in Colchester are trained to notice that kind of thing, and our security guards in Colchester deal with it before it becomes a crime number.
Manned guarding in Colchester isn’t only the city centre. Our manned guarding services in Colchester cover the whole city, from Lexden and Stanway to Highwoods, Greenstead and Berechurch. Every officer holds the SIA licence their post needs, and assignment instructions are written after we’ve walked your site.












The short video shows our security solutions in Colchester out on real sites, from manned guarding in Colchester’s retail parks to mobile security patrols in Colchester round empty units. Guards, door staff, key holders and mobile patrols in Colchester all report to one control room, so whoever answers your call can see what’s happening on your site.
We put together bespoke security services in Colchester around how your business runs: shift patterns, delivery slots and the weekends when a unit sits empty. Our residential security in Colchester is built for homeowners, private landlords and managing agents alike. Linked fire and intruder alarms are covered too, and close protection when an executive or VIP needs it.
For offices, it’s normally an officer on reception in the day and a locked, checked building at night. Security for offices in Colchester can start with one person, and our security guard services in Colchester grow from there.
Security for businesses in Colchester earns its money when nothing goes missing. That’s the test we’d want any of our security solutions in Colchester judged by.
Our third-party guard management software shows who’s on duty, where they are and what’s been checked across our security guarding services in Colchester. You can set tasks and read reports from your phone, without ringing anyone.
Each officer goes out with a radio, a reporting handset and a body camera. Each patrol point gets a GPS scan, so security patrolling in Colchester leaves a stop-by-stop record, from the city centre to Stanway. Missed checkpoints flag up straight away.

A city centre shop door and an industrial gate at 3am are different jobs. Our security guards in Colchester are trained for both, and for the moments that test them: a shoplifter who turns violent, a driver who won’t wait, an alarm in an empty building.
Security officers in Colchester working for us complete Emergency First Aid at Work (EFAW) and fire safety training before they’re deployed. Our professional security services in Colchester hold that standard on every contract.

Since 2021 we’ve learned where each sector usually goes wrong. Industrial security in Colchester tends to fail at the gate. Retail loses to a small group of repeat offenders. Hospitality struggles late at night.
As a manned guarding company in Colchester, we keep written procedures for each sector and brief officers on the one that fits your site.

Officers sign on by GPS at the start of each shift. If nobody’s signed on at your site, the control room is already sending cover.
Our alarm response in Colchester gets an officer to you within 45 minutes of activation, and key holding services in Colchester mean your staff don’t have to come out at night. Patrol vehicles use the A12, the A120 and the A133.

“Alpha Security handled security for our annual awards ceremony held at a venue in Colchester Town Centre, and the entire operation ran without a single issue. Their guards were suited for the environment, well-briefed on our guest list, and positioned strategically around the room. When a minor access dispute arose, it was resolved quietly and quickly. Our attendees commented on how smooth and secure everything felt.”
“For our county cricket ground in North Station Road, Alpha Security provides day-of security that covers gates, hospitality areas, and the boundary perimeter. Their guards are always well-presented, proactive, and reliable. When an unauthorized individual attempted to access the pavilion during a major fixture, their guard intervened immediately and resolved it without any scene. Outstanding.”
“Our specialist components factory in the Greenstead Quarter area required guards with the experience to work alongside production staff without disrupting workflow. Alpha Security provided exactly that. Their guards patrol at scheduled intervals without interfering with line operations and maintain a visible presence in areas of higher risk. It is a seamless, professional security operation.”
We cover Colchester and the surrounding area across CO1, CO2, CO3 and CO4. Our mobile patrol services in Colchester run between the city centre, Severalls, Stanway and Greenstead, so a vehicle is never far off.
As a local security company in Colchester, we keep SIA-licensed officers based across north Essex, which is how a sick call or a same-day booking gets filled without a gap.



A bit more than guards. As a security company in Colchester with its own control room, we run 21 specialist security services, and the same team works across Essex, London and the rest of the UK.
The everyday side is security guards, door supervision, key holding and alarm response, and checks on vacant property. On top of that there’s sector work: construction, factories, warehousing, logistics and distribution, gatehouses, retail, hotels, pubs and clubs, pharmaceutical, education, student accommodation, entertainment and art. And events, including corporate events, festivals and concerts, sporting fixtures and weddings. If yours isn’t listed, ask.
For a lot of sites, yes, and they’re among the most cost-effective security solutions in Colchester. Mobile patrols in Colchester mean an officer in a marked vehicle visits your premises several times a night, at times that change so nobody can learn the pattern. On each visit they check doors, shutters, fences and lighting, look for signs of forced entry, and log everything with GPS and photos.
They suit empty units, closed offices, yards with good fencing and building sites between phases. If you’ve got constant deliveries, cash on site or staff working late, a static guard is usually the better call. Plenty of clients mix the two, and any good security company in Colchester should offer both: manned guarding in the day, mobile security patrols overnight and at weekends. Security patrols in Colchester also cost far less than a guard on site all night, which is usually why people ask.
You’re not imagining it. Colchester Business Against Crime has described shoplifting as an epidemic, and security staff in the city have been punched, kicked and spat at. Police list theft in the city centre, Stanway and the retail areas among their current priorities.
A guard won’t stop every theft, but a visible officer at the door at the busy times puts most opportunists off. Our professional security guards in Colchester log every incident with times, descriptions and CCTV references so the police and the business crime partnership can build cases against repeat offenders. Business security in Colchester also covers the back door and the stockroom, which get far less attention than the tills.
It helps a bit, but we can’t enforce it. Colchester City Council’s city centre Public Space Protection Order targets public urination, open alcohol and drug use, intimidating behaviour while drunk or high, begging and loitering, anti-social riding of bikes and e-scooters, and unauthorised A-boards and flyposting. It was consulted on in 2023 as a three-year order, so a renewal is likely due.
Only police and authorised council officers can enforce it. What private security guards in Colchester can do is keep your doorway clear, refuse entry, write down exactly what happened and pass it to the people with the powers. Good records make action far more likely.
Daytime is about the gate; night-time is about the fence. Severalls, Whitehall and the estates around Stanway are a mix of trade counters, workshops, warehouses and offices, busy in the day and quiet after hours.
Manned guarding in Colchester’s industrial areas, and warehouse security in Colchester in particular, means logging vehicles, checking delivery paperwork and making sure the last person out really did lock up. Commercial security in Colchester also means watching the neighbouring units, because a break-in two doors down is often how thieves size up yours. Every quote for security for commercial properties in Colchester starts with a walk round, and our risk mitigation services in Colchester build from what we find. Sometimes a better lock is the answer, and we’ll say so.
Yes, and it’s the kind of mixed site where tailored security solutions in Colchester make sense. The Northern Gateway’s Colchester Leisure Park on the A12 has been fitting out a Vue cinema and Clip ‘n Climb, with more than 75 new jobs between them, next to Colchester Sports Park, a community football stadium and a David Lloyd club.
Leisure sites like that need a mix: access control in the day, someone keeping an eye on car parks and walkways in the evening, and a locked-down check after closing. Our officers can cover one unit or share cover across several, which keeps the cost down for each tenant.
We do. Student housing around Wivenhoe Park, Greenstead and the east of the city needs controlled entry, someone visible at night and officers who’ll ring for help when a student’s in a bad way rather than just writing it up.
Cover usually goes up in September and settles after freshers. Over the holidays, empty rooms get checked too. For managing agents with several blocks, community security in Colchester is often cheaper than a guard at each one, and our community security services in Colchester cover shared entrances, bike stores and bin areas.
Yes. Any security company in Colchester worth hiring should offer this, and it’s a growing part of our work. Essex Police list the safety of women and girls as a priority, especially around city centre taxi ranks, bus stops and the stations at night.
We can put an officer on your exit at closing time, walk staff to the car park, patrol the route between your door and the nearest rank, and stay until the last person has left. It costs less than people expect, and it’s one of the requests staff appreciate most.
Usually, yes. Ring in the morning and there’s a good chance someone will be on site the same day. After a break-in, or when another firm’s officer hasn’t turned up, emergency cover arrives within 2 to 4 hours. Planned cover usually starts 24 to 48 hours after we agree the plan.
You can hire security guards in Colchester for one night, one month or years, and you’re not tied into a long contract. If an alarm turns out to be a real break-in, our officer calls Essex Police, keeps the scene intact and stays until the building is secure. Call 023 8111 2814 or fill in the form and you’ll get an email back within 4 working hours.
We do. That covers homes left while owners travel, rentals between tenants, and open land waiting for development. The proposed Tendring and Colchester Borders Garden Community alone is planned for 7,750 homes, with a first phase of 837, and land like that attracts fly-tipping and trespass long before building starts.
Vacant property security in Colchester means visits at varied times and a full check each time. Private property security in Colchester suits owners who live elsewhere, and we can hold keys so nobody has to drive over at midnight when the alarm goes. Property security in Colchester for open land usually means gate and fence checks, randomised patrols and photos of anything new. Once homes are finished, the same developments often need concierge cover and security for residential properties in Colchester too.
