Frequently Asked Questions

Can't find what you're looking for? Get in touch with our team.

Our door supervisors have completed the full level of SIA certification and hold active licences from the Security Industry Authority (SIA) to provide security services as certified professionals. The extensive training provided for each of our door supervisors includes conflict management, first aid, and customer service. Each of our door supervisors has been approved by the SIA to work in this role and is trained to respond to a wide range of situations.

You will receive an in-depth assessment of your premises to help us understand the unique security challenges and needs you face. From this, we create bespoke security solutions tailored to your specific security needs and aligned with your business objectives. With our bespoke security solution, you can be assured that the first impression visitors have of your premises aligns with your brand identity. We offer fully flexible, SIA-approved door supervisors tailored to your exact requirements.

Our professional door supervision service is available 24/7. Security needs can arise at any hour. Our friendly staff are dedicated to providing you with reliable service whenever you need it, for all kinds of events, personal occasions, or general day-to-day venue operations. Our licensed security personnel can be booked on a flexible schedule.

Absolutely. With UK-wide coverage, we provide door supervision solutions for licensed premises across the UK. Our SIA-licensed door supervisors deliver consistent, high-quality, reliable service across all premises. All our door security personnel are trained to deliver the same high standards nationwide.

Through our sister company, A1 Teaching and Learning, we access the best-trained SIA door supervisors. We maintain strict hiring standards, ensuring all door staff are highly competent. Our ongoing training programmes ensure our SIA-approved door supervisors meet the highest standards in the security industry. Door supervisors are fully prepared and maintain a smart and professional appearance. Every door supervisor undergoes continuous assessment to maintain Security Industry Authority standards.

That scenario doesn’t happen with Alpha Security Services. We monitor each supervisor’s location in real time using GPS tracking through our central dispatch office. In the event of a deployment issue, we have on-call teams available to respond within 1 hour. Your premises will be secured at all times to ensure that no unauthorised individuals can enter while you are conducting business, and this reliability is a major reason our commercial clients rely on us to provide door security coverage during the peak hours of their busiest trading days.

Yes. We manage door supervision services for customers across a range of premises in the UK, from 12 to 150+ units, and have developed software to support these operations. The system manages all aspects of supervisor scheduling, deployment, performance management, and incident reporting, whether you operate 3 or 30 units. Our security firm is established for large-scale operations, and we have developed an operational structure that enables customers to add new premises to their security programme within days, not weeks.

Access to our complete operations platform is provided to you. Our live GPS tracking system displays the exact location of each of your supervisors in real time, as well as which staff are scheduled for which shift across all of your sites. As incidents occur, you receive real-time notifications, and you can immediately make changes to staff assignments based on current events. Each supervisor is equipped with body-worn cameras and encrypted two-way radios. All body-worn camera footage automatically uploads and integrates into incident reports, so when an incident occurs on a Saturday at 11:47 pm, you have the actual video with the proper timestamp ready to review on Sunday morning.

Our SIA-approved, trained, and licensed door supervisors receive a venue-specific briefing. We understand that each venue type has distinct security considerations. For example, pub door staff receive training on handling intoxicated customers. Hotel door security personnel are trained to provide customer service and to be friendly when interacting with guests. Door staff working at nightclubs are trained to manage large crowds.

We handle conflict at the door by resolving situations calmly before they escalate, protecting patrons, staff, and your venue’s atmosphere. How a refusal or dispute is handled at the door shapes your reputation as much as the outcome, so de-escalation always comes first, and physical intervention is a last resort used only within the law.

Our door supervisors are trained across 5 areas:

Conflict management and de-escalation resolve most situations through calm, professional communication rather than confrontation. Refusal handling manages entry refusals, ID rejections, and ejections firmly but courteously, keeping disputes away from other patrons. Lawful physical intervention applies only the minimum reasonable force necessary when de-escalation fails, using recognised, trained techniques. Welfare awareness identifies vulnerable, intoxicated, or at-risk customers and responds with care rather than enforcement. Evidence and reporting capture body-worn footage and written records that protect your venue against complaints and support any police follow-up.

Every venue has its own thresholds, so we agree on your policy on refusals, ejections, and escalation before deployment and brief officers on it for every shift.

Alpha Security Services offers a full scope of security services, including manned guarding, keyholding, CCTV monitoring, event security, and mobile patrols. All Alpha Security staff are multi-skilled in the security industry and highly qualified in at least one discipline. This includes SIA-licensed operatives who provide door supervision for nightclubs, pubs, and similar venues, as well as construction and retail security, among other services delivered by our SIA-accredited teams.
