Manned Guarding: Duties, Powers and Record-Keeping (2026)

Manned guarding turns on two things a quotation rarely spells out: what the officer on site is actually allowed to do, and whether the work can be proven if a client or a court asks. Both decide whether a contract holds.

Manned guarding is the day-to-day business of most UK security companies: a works gate, a residential block, a data centre, a construction site. The service looks straightforward. When something goes wrong, though, it comes down to the details that never make the quote: the limits of an officer's powers, and a defensible record of the work performed.

Both carry more weight in 2026. Martyn's Law and the tightening regime around critical national infrastructure are pushing documentation from good practice towards a contract requirement, and in competitive tenders the provable record is what separates the shortlist from the rest. This piece sets out where manned guarding sits: the duties, the legal limits, the cost, and the record-keeping that wins and keeps the work.

In brief: Manned guarding is the on-site protection of a fixed site by SIA-licensed security officers. Two things decide the contract: the legal powers of the officer (occupier's authority, citizen's arrest, no special powers) and a complete, tamper-evident record of the work, which a guard tour system like COREDINATE produces automatically as officers work.

What is manned guarding?

Manned guarding is the on-site protection of premises, people and assets by SIA-licensed security officers. It covers access control, patrols, incident response and basic safety checks at a specific site. Static site guarding keeps an officer posted at one location, mobile patrol covers several sites in a round, and BS 7499 is the recognised UK code of practice for both.

The site decides everything that follows. A data centre needs strict, documented access control and a monitored perimeter. A construction site needs visible presence against metal and plant theft, which is why construction is one of the largest sub-markets for guarding in the UK. A corporate reception puts front-of-house and visitor management first. Good manned guarding starts with a risk assessment of the specific site, not a generic patrol pattern lifted from another job.

Static site guarding, mobile patrol and in-house security

The terms overlap but mean different things. Manned guarding is the umbrella. Static site guarding is an officer posted to protect one site continuously. Mobile patrol is the touring form, where an officer visits several sites in a round rather than holding one, and keyholding and alarm response is the call-out variant that attends when an alarm activates. Where a company staffs security on its own works or industrial premises rather than buying it in, that is in-house or corporate security: the same static-guarding work, run internally and usually combined with reception, gatehouse and access duties.

What does a security guard do? The core duties

A security officer's core duties are controlling who enters the site, patrolling it on a set pattern, responding first to alarms and incidents, and carrying out basic health, safety and fire checks. Which duties dominate depends entirely on the site and its risk profile. What matters in a client audit is not that the officer was present, but that each task can be proven afterwards.

Access and reception control

Who gets onto the site, and who does not. The officer checks identity, runs the visitor book, issues and recovers passes, and holds vehicles at the barrier. How tight the regime is depends on the site: a data centre works with turnstiles and pre-registration, a construction site with visual checks and delivery notes, a reception with sign-in and a visitor badge. Every uncontrolled entry undermines the whole security scheme.

Patrols: static and GPS-tracked

At set intervals the officer walks the site and checks doors, windows, gates, lighting and hazards. On large sites such as industrial estates or solar farms, GPS-tracked patrols replace fixed checkpoints where physical points are not practical. Either way, the point that counts is the proof that each patrol actually happened, at the time it was meant to.

Incident and emergency response

When an alarm activates, an intruder is disturbed or a plant fault occurs, the officer is first on scene: make safe, report, record, and call in police, fire or ambulance where needed. On a sprawling site the lone officer can take several minutes to reach the location, which makes a practised first response more important, not less. The quality of the service shows in an orderly, traceable reaction, not in how quickly the incident is forgotten.

Health, safety and fire checks

Manned guarding increasingly picks up occupier duties: visual checks of fire doors and escape routes, reading plant values, flagging defective equipment, often as fire-marshal support out of hours. These run through digital checklists tied to a checkpoint, so the right form appears when the officer scans it, and anything out of place is captured on the spot with a photograph.

What powers does a security officer have (and not have)?

A UK security officer has no more legal power than any member of the public. The SIA licence certifies vetting and competence, not authority. An officer acts as the occupier's agent to control access and can make a citizen's arrest and use reasonable force, but has no power to search a person without consent and no general power to detain. Getting this right is where many providers are vague, and it matters.

The strongest lever is occupier's authority. There is no codified "house right" in England and Wales, so the officer acts as the agent of the occupier who controls the site. That authority lets the officer refuse entry, ask a person to leave, and, once that person becomes a trespasser, use reasonable force to remove them. It stops at the site boundary, and it carries no right to detain (beyond a citizen's arrest) and no right to search.

For holding a person, the relevant power is the citizen's arrest under section 24A of the Police and Criminal Evidence Act 1984. It applies to indictable offences only, when it is not reasonably practicable for a constable to make the arrest and a statutory condition is met, for example to stop the person making off before police can take over. Any force used must be reasonable in the circumstances under section 3 of the Criminal Law Act 1967 and common-law self-defence, with the reasonableness test set out in section 76 of the Criminal Justice and Immigration Act 2008. These are powers anyone has, not special authority granted to the security trade.

What the trade does require is a licence. Front-line manned guarding needs an SIA licence under the Private Security Industry Act 2001, earned through a Level 2 qualification plus identity and criminal-record vetting. Do not confuse two things that sound alike: the individual SIA licence is mandatory for every officer, while the SIA Approved Contractor Scheme is a voluntary company-level accreditation. An officer who knows the limits of these powers protects both the site and the employer from a liability claim.

Manned guarding for critical national infrastructure

The UK has no single law for the physical protection of critical national infrastructure. Instead, guidance from the National Protective Security Authority (NPSA), the NIS regime and Martyn's Law each set expectations, and CNI operators pass documentation and incident-reporting duties down to their guarding contractors through contracts. Auditable patrol evidence is becoming a tender pre-condition, not a nice-to-have.

That contractual cascade is the UK's real enforcement mechanism. Operators of essential services are audited against the Cyber Assessment Framework and NPSA guidance, both of which require them to manage supply-chain security and to specify what their security contractors document, retain and report. The forthcoming Cyber Security and Resilience Bill widens that regime on an all-hazards basis, physical threats included, and even creates a power to designate critical suppliers directly. In practice the operator writes the requirement into the guarding contract, and the guarding contractor has to be able to produce a Site Security Plan and a defensible incident and patrol record on demand.

Alongside CNI, Martyn's Law (the Terrorism (Protection of Premises) Act 2025) is the timely change most guarding buyers are asking about. It applies to publicly accessible premises with a capacity of 200 or more, with physical protective measures and a written assessment required at the enhanced tier of 800 and above. The SIA is the regulator, and the substantive duties come into force no earlier than April 2027. It is a venues-and-premises duty, not a general CNI patrol-documentation mandate, so the honest framing is this: it will not license your officers, but it will make venue clients expect procedures, trained staff and a record that measures actually happened.

The scale behind all this is real. The SIA reported over 460,000 licence holders and more than 519,000 active licences at the end of 2025, with roughly 58,000 badges in the contract security guarding category, on official monthly-updated gov.uk figures. This is a large, licensed and growing workforce, and the pressure on it is shifting from simple presence to the provable handling of security-relevant events.

Records: why documentation decides the contract

In manned guarding, the contract lives or dies on the record. Client audits, liability claims and tenders all demand a complete, tamper-evident account of every patrol and incident. A paper occurrence book delivers that poorly: it can be filled in after the fact, it goes missing, and it carries little weight in a dispute.

At a client audit, the buyer wants to see that the agreed patrols happened. In a liability case, after a break-in or an injury, the contractor has to show the duty was met. And in a tender or PQQ, the contract goes to the provider who can promise the client transparent, audit-ready reporting, increasingly benchmarked against BS 7499 record-keeping and, for CNI work, the operator's own contract terms. A handwritten log satisfies none of these when it counts.

A digital guard tour system produces that record as officers work. Each checkpoint scan lands in the digital occurrence book with a timestamp, logging activity chronologically, and entries become tamper-evident once uploaded so they cannot be quietly revised after the event. On large sites, GPS-tracked patrols cover the ground where fixed checkpoints are impractical, and key handovers are logged with a timestamp instead of running on trust.

From that data the portal produces reports as a PDF at the press of a button, and, where the client wants it, an optional client login gives the buyer their own view of the activity released to them. The same data protects the officer. For lone officers on a night shift, the system pairs location with a lone worker and man-down alarm in line with BS 8484, so a collapse or non-response raises the alert without the officer having to act.

How much does manned guarding cost?

There is no sector-wide wage tariff in UK manned guarding, so a single hourly rate tells you little. Cost is anchored on the National Living Wage floor and the voluntary Real Living Wage, then driven by the cover pattern, the SIA licence level required and the site's risk profile.

The biggest driver is the cover pattern: spot patrols cost a fraction of a 24/7 manned post, which has to pay for cover across nights, weekends and holidays. On top of that sit the qualification and licence level the site demands, the employer on-costs and margin, and any technology in the scheme. The Real Living Wage matters here beyond ethics, because it is increasingly written into public-sector security procurement, from NHS estates to Crown Commercial Service frameworks, so a bid priced below it can be non-compliant before quality is even assessed. A realistic charge rate reflects the cover factor and the licensed wage floor, which is why a flat number quoted without the cover pattern is close to meaningless.
