Security pricing depends on the service, number of officers, hours, risk level, location, supervision requirements and whether the cover is one off or ongoing. Semper Security prices each requirement around the actual operation rather than using one generic rate. Request an exact quote and we can price the cover you need.
We provide manned guarding, event security and crowd management, door supervision, mobile patrols, key holding and alarm response, lock and unlock services, concierge security, retail security, CCTV monitoring, site and vacant property security and related operational support. View all security services.
Semper Security is based in Coventry and supports clients across Coventry, Warwickshire and the wider West Midlands. Wider deployment can also be considered depending on the requirement. Ask us about your location.
Short notice cover may be possible depending on officer availability, licence requirements, location, shift length and risk. The earlier you contact us, the more effectively we can plan the right deployment. For urgent requirements, contact Semper Security directly.
Yes. We support one off events, temporary cover, ad hoc assignments and ongoing contracts. The operating plan, supervision and reporting are tailored to the length and complexity of the requirement.
Useful information includes the site or venue address, dates and hours, expected attendance where relevant, number of entrances, known risks, whether alcohol is being served, any searching or access control requirement, existing procedures and whether you need supervisors, patrols or response cover.
Minimum booking requirements can vary according to the service, number of officers, location and deployment. Event and private security assignments may need minimum staffing or hours so the operation is safe and commercially practical. We will confirm this clearly when quoting.
Where the assignment is ongoing, we aim to build consistency into the deployment where practical. Familiarity with the site, team and procedures can improve communication and operational understanding, while still maintaining enough trained cover for absence and changing requirements.
There is no single number that suits every event. Staffing should be based on the event risk assessment, crowd size and profile, venue layout, entrances and exits, alcohol, search requirements, restricted areas, operating hours and emergency arrangements. HSE guidance makes clear that crowd safety controls should be proportionate to the risks. Explore Event Security.
There is no universal UK security guard to guest ratio that automatically applies to every event. The appropriate staffing level depends on risk, venue arrangements and the event plan, and may also be affected by premises licence conditions, local authority requirements or Safety Advisory Group advice.
A steward is commonly focused on customer assistance, directions, ticketing, crowd information and safety duties. Security officers carry out licensable security activity where the correct SIA licence is required. Many events use both roles with clearly defined responsibilities.
A door supervisor licence covers a wider range of licensable activity and is commonly required where security is provided at licensed premises or events involving alcohol and entry control. A security guarding licence does not replace a door supervisor licence where door supervision is required.
Bag searches should be planned in advance and carried out lawfully, consistently and in line with the venue or event entry conditions. Search arrangements must also avoid creating unsafe crowd pressure or excessive queues. We can help plan search positions, staffing and escalation procedures.
Yes, subject to availability. If female officers are operationally important for search arrangements, safeguarding considerations or customer experience, tell us during planning so this can be built into the deployment.
Yes. Overnight protection can be arranged for event infrastructure, equipment, temporary structures and controlled areas before, during or after an event, depending on the site and risk assessment.
Yes. Event organisers may need to liaise with local authorities, emergency services and a Safety Advisory Group depending on the event. Semper can support the security and crowd management elements of the operational plan and provide relevant security information for planning.
Book as early as you reasonably can, particularly for large events, weekends, licensed events or dates when security demand is high. Early engagement gives more time to assess the venue, confirm staffing, identify supervisors, plan access and search arrangements and coordinate with other event stakeholders.
Yes. Security planning can include ingress, egress, search positions, queue management, restricted areas, emergency access and officer deployment. These arrangements should work with the wider event plan rather than being treated as a separate security exercise.
Manned guarding can include access control, visitor and contractor checks, patrols, incident response, opening and closing procedures, monitoring vulnerable areas and maintaining a visible security presence. The exact duties are agreed for each site. View Manned Guarding.
Manned guarding is usually more appropriate where a continuous on site presence is needed. Mobile patrols can suit lower risk locations that need visible checks at intervals rather than a permanently stationed officer. Some clients use both services together.
Where a role involves licensable activity, the officer must hold the correct SIA licence. Licence status can be checked through the official SIA public register. Semper also manages licence and compliance checks as part of deployment controls.
Security assignments require appropriate identity, employment and screening checks. Semper uses structured recruitment and compliance processes and references BS 7858 screening requirements when assessing security personnel before activation for work.
Yes. A professional deployment should be based on the duties, risks, escalation routes and emergency arrangements for the specific site or event. Officers should understand what is expected before taking responsibility for the assignment.
Yes. Where the environment needs a customer facing presence, concierge security can combine access control, visitor management and professional front of house support. View Concierge Security.
Body worn cameras can be used on suitable assignments where the operating procedure, client requirement and circumstances support their use. Any recording should be handled in accordance with the applicable data protection and evidence procedures.
First aid competence is an important part of operational readiness. Semper requires appropriate first aid training for its security workforce and also considers any additional site or event specific first aid arrangements during deployment planning.
A professional key holding service allows an authorised security provider to retain controlled access keys so a trained responder can attend when required. Alarm response can include attending the premises, checking for signs of an incident, following agreed escalation procedures and securing the site. View Key Holding and Alarm Response.
The process depends on the agreed response instructions. Typically the responder attends, assesses the site, follows access and escalation procedures, records the attendance and takes the agreed next action if damage, intrusion or another issue is identified.
Response time depends on location, traffic, officer position and the circumstances at the time of activation, so a responsible provider should not promise one universal arrival time. The agreed service should define the response process and escalation arrangements.
Yes. Multi site key holding and response arrangements can be discussed for businesses with several premises. Each site should have clear access information, escalation contacts and response instructions.
It can. Businesses often use professional key holding so employees or managers do not have to be the first person attending an alarm activation out of hours. The right arrangement depends on your alarm system and site procedures.
Key holding is centred on secure key custody and authorised access when a response is required. Mobile patrols are security visits to check the premises at planned or variable times. They can be used separately or together as part of an out of hours security plan.
A patrol can include checks of doors, gates, vulnerable access points, external areas, signs of damage, unusual activity and other agreed points. The patrol scope should be written into the site instructions so the officer knows exactly what must be checked and reported. View Mobile Patrols.
Yes. Lock and unlock services can support businesses that want a security professional to open or secure the premises at agreed times, carry out basic checks and follow the site's access procedures. View Lock and Unlock.
The right security model depends on the value of plant and materials, perimeter vulnerability, access points, working hours, location and history of theft or trespass. Options can include guarding, access control, mobile patrols, CCTV, lock and unlock and alarm response. View Site Security.
They can be useful where a permanent guard is not proportionate. Patrols can provide a visible presence, inspect access points and identify obvious changes or damage. Higher risk vacant sites may need additional measures.
Retail security supports staff and customers through visible deterrence, incident response, loss prevention activity, monitoring and professional handling of problems within the store or retail environment. View Retail Security.
It depends on the risk. CCTV can provide monitoring and evidence, but it does not physically control access or provide an immediate on site presence. Higher risk environments often benefit from combining technology with guarding, patrol or response services.
Yes. Education security can include access control, guarding, concierge style duties, event support and visible reassurance. The deployment should reflect safeguarding, site procedures, visitor management and the operating environment.
Yes. Commercial and corporate environments can use guarding, concierge security, visitor management, lock and unlock, patrols, key holding and alarm response. The mix depends on the building, tenant arrangements, hours and risk.
The government provides a public SIA register for checking whether an individual holds the correct security licence. Clients should ensure people carrying out licensable private security activity hold the appropriate licence for the role.
BS 7858 is a British Standard used for screening individuals employed in security environments. It provides a structured framework for identity and employment history screening and is commonly referenced by professional security providers and buyers.
No. As of September 2026, the Terrorism (Protection of Premises) Act 2025, commonly called Martyn's Law, has received Royal Assent but is not yet in force. The SIA currently says it is expected to commence in spring 2027.
No. The Act has defined scope and requirements for qualifying premises and qualifying events. Whether a particular venue or event is in scope depends on the legislation and official guidance. Organisations should use current Home Office and SIA guidance when assessing their position.
Responsibility under Martyn's Law cannot simply be transferred to a security contractor. Where appropriate, Semper can support operational security planning, staffing, access control, crowd management and response arrangements, but the responsible person or organisation remains responsible for meeting its legal duties.
The SIA recommends that organisations that may be in scope start by understanding whether the legislation could apply to them and reviewing current Home Office guidance. Security arrangements should form part of wider preparedness rather than being treated as a substitute for the responsible organisation's duties.
