Office Security Services UK: 2026 Costs & Guide

Last updated: 7 September 2026

Office security services UK-wide combine SIA-licensed manned guarding, CCTV monitoring, access control and key holding to protect staff, assets and premises. Robbery of business property rose 50% to 15,520 offences in the year ending March 2026, according to the Office for National Statistics, making professional protection a board-level priority for UK businesses.

Key Takeaways

• Robbery of business property rose 50% to 15,520 offences in England and Wales in the year ending March 2026, according to the Office for National Statistics.
• The UK's private security services industry is forecast to reach £10.1 billion in revenue in 2026-27, according to IBISWorld.
• Every security guard working in the UK must hold a Security Industry Authority (SIA) licence under the Private Security Industry Act 2001, unless a specific exemption applies.
• Around 8% of business premises experienced burglary or attempted burglary, with retail and wholesale sectors among the most affected, per the Office for National Statistics / Commercial Victimisation Survey.
• Priority First's operational data shows 24 sites now run on a single security platform, up from 18, with more than 4,900 photo-backed patrols completed as of August 2026.

What Are Office Security Services?

Office security services are the combination of manned guarding, electronic surveillance and physical access controls that businesses use to protect their premises, staff and assets during and outside working hours. In the UK, this typically means SIA-licensed security officers, CCTV monitoring, key holding and alarm response delivered either by an in-house team or an outsourced specialist provider.

The sector sits within a wider security systems services market that is forecast to see continued growth in revenue over the coming years, with a healthy compound annual growth rate over five years (IBISWorld). That growth is not abstract. Crimes against individuals in England and Wales swelled by 7% in the year through March 2026, according to the Office for National Statistics, cited by IBISWorld, and business premises have not been insulated from that trend.

Most office security contracts in London and across the UK bundle several disciplines together: a static or mobile guarding presence, CCTV monitoring with remote escalation, out-of-hours key holding, and rapid alarm response. Some also fold in front-of-house concierge duties, since a well-trained receptionist or building host is often the first line of defence against unauthorised access. The Private Security Industry Act 2001 is the legislation that underpins licensing for almost every role in this space, and it's the reference point any procurement team should start from.

Why Office Security Has Become a Board-Level Issue

Office security has moved from a facilities line item to a governance concern because the financial and reputational stakes of a breach have grown. The British Retail Consortium reported that retailers spent a record £1.8 billion on crime prevention in 2023-24, driving more guarding, CCTV and incident response contracts for security businesses across the wider commercial sector (IBISWorld, citing British Retail Consortium).

Office buildings face a distinct risk pattern compared with retail units. A commercial office's exposure often peaks precisely when occupancy drops — evenings, weekends and holiday periods — when deliveries, contractors and cleaning crews still need access but staff numbers fall to near zero.

How Much Do Office Security Services Cost in the UK?

Office security costs in the UK vary by location, hours of cover and whether guarding is static, mobile or hybrid with CCTV. A single SIA-licensed officer providing evening and weekend cover for a mid-sized central London office typically costs in the region of £15,000 a year, based on Priority First's delivered contracts in Chelsea and Knightsbridge.

Pricing depends heavily on postcode, shift patterns and whether the contract includes ancillary services such as key holding, alarm response or concierge duties. Prime central London locations such as Mayfair, Knightsbridge and Chelsea generally command a premium over outer London or regional rates, reflecting both cost of living and client expectations around presentation standards.

Regional Price Guide (Illustrative)

Region	Typical hourly rate (single officer)	Typical annual cost (part-time cover)
Prime Central London (Mayfair, Knightsbridge, Chelsea)	£16-£22/hour	£15,000-£25,000+
Outer London / West London	£13-£18/hour	£10,000-£18,000
Major regional cities (Birmingham, Manchester)	£11-£15/hour	£8,000-£14,000
Regional UK (e.g. Bedfordshire, West Midlands)	£10-£14/hour	£7,000-£12,000

These figures are illustrative ranges built from typical market patterns and Priority First's own contract data; they are not attributed to any external study.

Worked Scenarios

A Chelsea office building needing evening and weekend cover to bridge the gap between staff departure and building lock-up commonly sits at around £15,000 a year for a single SIA-licensed officer, based on Priority First's delivered contracts in that area. A larger Mayfair office wanting 24/7 static guarding alongside CCTV monitoring and key holding will typically pay several multiples of that figure, since round-the-clock cover requires multiple officers across a shift rota rather than one person working extended hours.

A mixed-use development wanting mobile patrols rather than a static presence — checking multiple entry points, car parks and communal areas on a rotating schedule — can often reduce costs compared with dedicated static guarding at every entrance, while still providing a visible deterrent.

Ways to Reduce Office Security Costs

• Combine guarding with concierge duties so one trained team member delivers front-of-house welcome and security oversight simultaneously.
• Use CCTV monitoring to reduce the hours requiring a physical officer, particularly overnight when footfall is minimal.
• Bundle key holding and alarm response into a single contract rather than procuring them separately.
• Right-size shift patterns to actual risk periods — many offices need less cover at 3pm than at 7pm when the building empties.
• Consolidate multi-site contracts with a single accountable provider rather than managing several suppliers across a portfolio.

Alternatives to Static Guarding

CCTV monitoring, mobile patrol services and hybrid models are all viable alternatives or complements to a permanent static guard. A business with lower footfall or a smaller premises might rely primarily on remote CCTV monitoring with an escalation protocol, calling in a mobile response officer only when an alarm triggers or an incident is flagged.

In-House vs Outsourced Office Security: Which Is Right for Your Business?

The choice between building an in-house security team and outsourcing to a specialist provider comes down to control, cost predictability and access to trained, licensed personnel at scale. In-house teams offer direct line management but carry recruitment, training, licensing renewal and holiday cover burdens that many facilities managers underestimate.

Outsourced providers such as Priority First carry the administrative weight of SIA licence verification, shift scheduling, sickness cover and ongoing training, while remaining accountable to a single service level agreement.

Factor	In-house security team	Outsourced security provider
SIA licence management	Business responsible for verifying and renewing	Provider verifies and manages compliance
Cover for sickness/holiday	Requires internal backup staff	Provider guarantees continuous cover
Cost structure	Fixed salaries, National Insurance, pension	Variable contract cost, often lower overhead
Speed to scale up/down	Slow — recruitment cycles	Fast — contract variation
Specialist skills (canine, CCTV, close protection)	Rarely available in-house	Available as add-on services
Accountability	Internal management only	Single accountable partner with SLA

Many mid-sized businesses find a hybrid model works best: a small in-house facilities team supported by an outsourced SIA-licensed guarding contract for the hours and duties that need specialist coverage.

Is an SIA Licence a Legal Requirement for Office Security Guards?

Yes. Under Section 3 of the Private Security Industry Act 2001, anyone carrying out licensable "security guard" activities in the UK must hold a valid Security Industry Authority (SIA) licence, unless a specific exemption applies. The SIA is the statutory regulator overseeing the private security industry in England, Wales and Scotland, and its licensing scheme covers roles including manned guarding, door supervision and CCTV operation.

The Security Industry Authority's regulated professions guidance confirms this legal requirement in full, and businesses procuring security services should verify licence numbers as a matter of routine due diligence. Official application guidance is published on GOV.UK's SIA licence page.

Failing to check this exposes a business to significant risk. An unlicensed individual operating as a security guard commits a criminal offence, and a business knowingly engaging unlicensed personnel can face reputational and contractual consequences, particularly where insurance policies specify licensed guarding as a condition of cover.

Priority First's Managing Director puts the cost-quality trade-off plainly:

"When a quote is dramatically cheaper than the rest, the saving has come from somewhere — usually the officer's pay, their training, or the vetting behind them. Tired, underpaid officers on your site are a risk you have paid to acquire. Value in this industry means knowing exactly what your money buys." — Mo Hassan, Managing Director, Priority First

What Should an Office Security Risk Assessment Cover?

A security risk assessment is a structured review of a building's vulnerabilities, access points and operational patterns used to determine the appropriate level and type of security cover. It should examine physical access points, out-of-hours occupancy, delivery and contractor management, existing CCTV coverage, and the specific threats relevant to the business's sector and location.

The Health and Safety at Work etc. Act 1974 places a general duty on employers to ensure the health, safety and welfare of employees, and the Health and Safety Executive's guidance on workplace violence makes clear this extends to protecting staff from violence and aggression, including from third parties on site. Lone workers deserve particular attention: the HSE's lone working guidance sets out specific employer duties where staff work without direct supervision, a scenario common in reception areas and out-of-hours facilities roles.

A thorough building audit typically covers:

• Perimeter and entry point security — locks, barriers, fencing and controlled access systems.
• CCTV coverage gaps — blind spots at entrances, loading bays and stairwells.
• Out-of-hours occupancy patterns — who has access, and when, once staff numbers drop.
• Delivery and contractor management — how goods and visitors are logged, checked and escorted.
• Alarm response protocols — who is notified, and how quickly, when an activation occurs.
• Key holding arrangements — who holds keys, and whether handover is documented.

Priority First's own building audit and risk assessment service applies this structured approach across client sites, feeding directly into staffing and technology recommendations.

How Does Manned Guarding Work Alongside CCTV Monitoring?

Manned guarding and CCTV monitoring work together as complementary layers, with physical officers providing presence, judgement and rapid intervention while remote monitoring extends coverage to hours and areas a static guard cannot watch continuously. CCTV operators flag suspicious activity and escalate to on-site officers or emergency services, while officers on patrol provide the visible deterrent and physical response that cameras alone cannot deliver.

This layered approach matters because office buildings behave very differently outside standard working hours. An office's risk profile effectively inverts at close of business: deliveries, contractors and access needs continue, but occupancy drops towards zero, leaving the building most vulnerable exactly when fewer people are watching.

Priority First has addressed this pattern directly for office clients in Chelsea and Knightsbridge, where SIA-licensed officers cover the site with every patrol, incident and handover logged on the company's platform. Checkpoints are completed with a photograph, GPS location and timestamp, so delivered cover is provable rather than simply asserted — a distinction that matters when a client wants evidence, not assurances, that a patrol actually happened.

That evidence standard scales across a portfolio. Priority First's operational data shows patrols per building across a 16-building prime estate running at 250-280 photo-backed patrols, all previously unprovable under a paper occurence book system. Across the wider portfolio, the company has logged more than 4,900 photo-backed patrols across 24 sites, supported by 11 or more field officers operating on a single system as of August 2026.

Mo Hassan, Managing Director of Priority First, describes the cultural shift this technology supports:

"The old image of security — arms folded, saying no — actively damages the businesses it is meant to protect. The modern standard is that the same officer is the most helpful person in the building and the reason trouble goes elsewhere. Those are not opposites; done properly, each makes the other more effective." — Mo Hassan, Managing Director, Priority First

Key Holding and Alarm Response: The Overlooked Essential

Key holding is the practice of a security provider holding a copy of a building's keys and responding to alarm activations on the client's behalf, typically within an agreed response time. This matters because burglary remains a persistent risk to commercial premises: police in England and Wales recorded 245,284 burglary offences in the year ending March 2026, an 8% decrease compared with the previous year, of which 78,707 were non-domestic offences (Office for National Statistics).

Separately, around 8% of business premises experienced burglary or attempted burglary, with retail and wholesale sectors among the most affected, according to the Office for National Statistics / Commercial Victimisation Survey. Office buildings are not immune, particularly those with valuable IT equipment, cash handling or client-confidential material on site.

A reliable key holding and alarm response arrangement removes the burden from an individual member of staff having to leave home at 2am to attend a false alarm, replacing it with a trained officer who can assess the situation and escalate appropriately.

Choosing a Reputable Office Security Provider in the UK

Choosing an office security provider means verifying SIA licensing compliance, checking the provider's track record across comparable buildings, and confirming how service delivery is evidenced rather than simply promised. The British Security Industry Association (BSIA) is the UK's leading trade association for the professional security industry, representing a significant share of UK security products and services and helping set standards that buyers can reference during procurement.

Facilities managers running a tender process should look beyond price alone. Ask how patrols are logged, how incidents are escalated, and whether the provider can demonstrate — not merely describe — the coverage delivered each month.

What to Ask a Prospective Security Provider

• Can you confirm every officer's SIA licence number before deployment?
• How are patrols and checkpoints evidenced — paper logs, or timestamped, photo-backed records?
• What is your escalation protocol for a triggered alarm out of hours?
• How quickly can new sites go live, and what does onboarding involve?
• Do you provide a single point of accountability across security, key holding and facilities management, or are these separate contracts?

Priority First's own onboarding data offers a useful benchmark here: new sites, including a 10-checkpoint serviced residence, have gone live within a fortnight, with the first provable patrol typically achieved within days rather than the weeks of "bedding in" that a new contract traditionally requires. One recent onboarding recorded 152 photographed checkpoints on a single mixed-use development, rising from zero before the platform was introduced, with 100% of checkpoint completions carrying a watermarked photo.

This kind of evidenced delivery is echoed in client feedback. One client wrote: "We recently hired Priot[i]y First to handle the security needs for our business, and we couldn't be more impressed! From the initial consultation to the implementation of security systems, their team was professional, knowledgeable, and incredibly responsive... Since then, the monitoring service has been top-notch—quick responses, clear communication, and the peace of mind we've been looking for." — James Burmingham

Your Office Security Services Checklist

• Verify every officer's SIA licence before they are deployed to your site.
• Commission a structured risk assessment covering entry points, out-of-hours occupancy and delivery management.
• Confirm how patrols and checkpoints are evidenced — insist on timestamped, photo-backed records over paper logs.
• Match shift patterns to actual risk periods, not just standard office hours.
• Bundle key holding and alarm response into your core contract to remove single points of failure.
• Check the provider's escalation protocol for out-of-hours alarm activations.
• Ask how quickly a new contract can go live and what onboarding involves.
• Review your contract annually against current crime data and any changes to your building's occupancy pattern.

FAQ

What is an SIA licence and is it a legal requirement for office security guards in the UK?

An SIA licence is a legal permit issued by the Security Industry Authority that authorises an individual to carry out licensable security work in the UK. It is a legal requirement under the Private Security Industry Act 2001 for anyone performing security guarding duties, and businesses should verify licence numbers before engaging any guard, as confirmed by GOV.UK's official guidance.

How much does office security cost per hour in the UK?

Office security costs typically range from around £10 to £22 per hour depending on location, with prime central London postcodes such as Mayfair and Knightsbridge commanding the higher end of that range. A part-time evening and weekend cover contract for a single officer in Chelsea has cost in the region of £15,000 a year based on Priority First's delivered contracts.

What is the difference between in-house and outsourced office security services?

In-house security means a business directly employs and manages its own guards, while outsourced security means a specialist provider supplies SIA-licensed personnel under a service agreement. Outsourcing typically removes the burden of licence verification, sickness cover and training from the client, while in-house teams offer more direct day-to-day management.

Do businesses need SIA-licensed security guards or can they use in-house staff?

Any individual carrying out licensable security guard activities must hold a valid SIA licence, regardless of whether they are employed directly or supplied by a contractor. There is no exemption simply because a guard is an in-house employee rather than an outsourced contractor.

What should be included in an office security risk assessment?

An office security risk assessment should cover perimeter and entry point security, CCTV coverage gaps, out-of-hours occupancy patterns, delivery and contractor management, alarm response protocols and key holding arrangements. Employers also carry duties under the Health and Safety at Work etc. Act 1974 to protect staff from violence, as set out in HSE guidance.

How do I choose a reputable office security company in the UK?

Choose a provider by verifying SIA licence compliance for every officer, asking how patrols and incidents are evidenced, and checking their track record across comparable buildings. The British Security Industry Association is a useful reference point for understanding industry standards during procurement.

What security measures reduce the risk of office burglary or break-ins?

Effective measures include controlled access points, CCTV coverage of all entrances and loading bays, out-of-hours patrols, key holding with rapid alarm response, and regular risk assessment reviews. Non-domestic burglary accounted for 78,707 of the 245,284 burglary offences recorded in England and Wales in the year ending March 2026, according to the Office for National Statistics, underlining why layered measures matter.

How does CCTV monitoring work alongside manned security guarding for offices?

CCTV monitoring provides continuous remote surveillance and escalates suspicious activity to on-site officers or emergency services, while manned guards provide visible deterrence and physical response capability. Together they cover the gaps that either measure alone would leave, particularly during low-occupancy periods when a building is most vulnerable.
