Commercial site security is not simply a matter of installing cameras or locking the front door. Property managers, facilities teams, construction managers and business owners need a coordinated plan that protects people, premises, equipment and day-to-day operations. A warehouse with a vehicle yard, an occupied office, a building project and a temporarily vacant unit each present different risks.
The Home Office’s 2023 Commercial Victimisation Survey estimated that 26% of business premises in England and Wales experienced at least one of the offences it measured during the previous 12 months. Theft affected 14% of premises and burglary, including attempts, affected 8%. These are national premises-level estimates, not Hampshire crime rates. The survey covers selected offences and measures computer misuse separately from its overall crime figure, so use the data as context rather than as a prediction for any individual site. 1
For businesses in Southampton, Winchester, Portsmouth, Eastleigh and Fareham, the most useful starting point is a site-specific review of how people, vehicles and valuable items move through each property. A control that suits one premises may not fit another.
Start with a site-specific risk assessment
Walk the site in daylight and, where safe, after dark. Consider how it operates during opening, deliveries, shift changes, weekends and shutdowns. Map boundaries, entrances, loading bays, car parks, ground-floor and roof access, poorly lit areas and neighbouring land uses. Identify what is most exposed or valuable, including plant, tools, stock, vehicles, fuel, building materials and equipment containing business data.
Assess both likelihood and consequence. A recurring access-control fault, for example, may have different implications depending on whether it exposes staff, valuable equipment or a critical part of the operation. Record current controls, who owns each task and any temporary vulnerabilities, such as a damaged fence, a newly delivered plant item or an open service entrance. Review the plan after an incident, site change, new shift pattern or change in asset value.
Make the plan operational. Define who checks alarms, who authorises visitors, who holds keys, how faults are escalated and what staff should do if they encounter an intruder. A written procedure only helps when it is understood and workable on a busy day.
Build layers, not isolated fixes
A practical plan combines visible deterrence, physical delay, detection and a clear response. Begin with good housekeeping: keep sightlines clear, secure bins, remove items that could assist access and avoid leaving high-value goods visible from windows. Police.uk advises businesses to maintain the exterior, secure vulnerable openings and service doors, keep bins away from access points, and provide sufficient lighting, especially around loading areas. 2
Next, check gates, fencing, doors, windows, rooflights and delivery entrances for condition and suitability. Measures should match the identified risk and the building. Keep a maintenance record for locks, gates, lighting, alarms and cameras. If a site is leased or shared, agree proposed changes with the landlord or managing agent and check any insurer requirements before work starts.
Good lighting supports visibility and can help cameras capture usable images at night. Review dark areas, loading points and access routes. Timers, dusk-to-dawn controls or motion sensors may suit different sites, but avoid glare or nuisance to neighbours. ProtectUK recommends proportionate measures that are fit for purpose and maintained; it also advises checking CCTV coverage and establishing an agreed process for alarm activations. 3
Control access, visitors and keys
Separate the arrangements for staff, contractors, delivery drivers and visitors. Decide which doors and areas each group may use, and make sign-in, escort and pass-return procedures proportionate to the site. On larger properties, issue access credentials by role and remove or change permissions promptly when a worker leaves or a contract ends.
Treat mechanical keys as controlled assets. Keep a current register of issued keys and authorised keyholders; restrict master keys; avoid labels that identify the address or sensitive areas; and establish a process for reporting lost keys. When taking over a leased or purchased premises, review who may still hold access and discuss any lock changes with the landlord and insurer. The National Business Crime Centre’s premises guidance highlights the risk of unknown former keyholders and the value of reviewing locks and smart-access permissions. 4
Manage vehicle access as carefully as pedestrian entry. Confirm deliveries, use designated routes and keep a record of expected visitors. Separate visitor routes from plant movements where practicable, and make sure gates are not routinely left open.
Construction sites need daily security checks
Construction sites change quickly. An open excavation, a newly delivered set of tools, incomplete doors or temporary fencing can alter the risk overnight. HSE says construction sites need measures to manage access across defined boundaries and steps to exclude unauthorised people. It advises planning, providing and maintaining suitable boundaries in light of the work, surroundings and site characteristics. 5
At the end of a shift, secure the perimeter, lock away plant and tools, store materials within the boundary, and check that openings and excavations are protected. Keep ladders and other access equipment from creating an easy route into the site. These security steps should be coordinated with site safety, delivery plans and emergency access.
The National Business Crime Centre’s building-site guide recommends reviewing perimeter security, CCTV and alarms, lighting, plant and machinery, signage and patrol arrangements. It also advises recording equipment details and reporting crime. 6 For a dedicated service overview, see construction site security.
Plan for vacant or temporarily empty premises
An empty building needs an owner, an inspection routine and a clear escalation path. Agree who checks the property and how often, and what they should record: visible damage, attempted entry, leaks, fire hazards, changes to neighbouring conditions and faults with locks, lighting or alarms. Keep deliveries and waste from accumulating, secure access points and review keyholder details before holidays or planned closures.
The National Business Crime Centre advises reviewing vacant property risks layer by layer—from the boundary to the building—and considering how surveillance, utility changes and physical security interact. A change to electricity or water can affect alarms, cameras or fire arrangements, so plan it rather than switching services off without review. 7 Learn more about vacant property security.
Decide when external security support fits
Some sites may benefit from a staffed presence during defined hours, access management or a visible point of contact. Others may need periodic checks across a site or several locations. Keyholding and alarm response may be worth considering where a business does not want employees routinely attending alarm activations. These are options to assess, not universal requirements; compare the service scope with the site’s operating needs and risk assessment.
Before appointing a provider, set out the locations, hours, duties, access permissions, reporting expectations, escalation contacts and exclusions. Ask how activity is recorded and how a service interruption or unavailable keyholder is handled. Confirm that the required service is available for the specific location and dates rather than assuming coverage from a general service description. You can review static guarding, mobile patrol services and keyholding and alarm response as possible service options.
Commercial site-security checklist

- Tools, plant, vehicles and high-value stock are secured and identifiable.
- Construction-site materials, plant and public-facing hazards are controlled at close of work.
- Vacant premises have a named inspection owner and escalation route.
- Staff know how to report incidents and when to contact emergency services.
