What is key holding and alarm response?
Vigil holds spare keys to your premises and responds to alarm activations 24/7 with SIA-licensed officers.
Key holding and alarm response is a managed security service that eliminates the need for business owners, facilities managers, or nominated keyholders to attend their premises in the middle of the night when an alarm activates. Vigil holds spare keys to your property in a secure, BS7558-approved key safe at our operations centre. When your intruder alarm, fire alarm, or panic alarm activates out of hours, our 24/7 control room receives the signal and immediately dispatches an SIA-licensed mobile patrol officer to your site.
The officer arrives within our contractually guaranteed response time — typically 20 minutes for central London, 30 minutes for outer London — and uses our held keys to gain entry. They investigate the cause of the alarm activation by searching the premises systematically, identifying whether the activation was caused by genuine intrusion, environmental factors (e.g., wind, temperature changes), equipment fault, or user error. If a security breach is identified, the officer secures the scene and contacts the police. If the premises are secure, the officer resets the alarm, locks up, and provides you with a detailed attendance report including photographs and timestamps.
This service is essential for businesses with insurance requirements for out-of-hours alarm response, premises located in high-risk areas where false alarms are frequent, and organisations where key personnel live far from the site or where attending in the early hours creates safety or operational risks. Key holding and alarm response is widely used across retail stores, office buildings, warehouses, healthcare facilities, and construction sites throughout Greater London.
Why businesses choose Vigil for key holding
Guaranteed response times, secure key storage, SIA-licensed officers, and Greater London coverage.
Most alarm response companies operate on a best-efforts basis with vague response time commitments. Vigil provides contractually guaranteed response times written into our service level agreement. For central London boroughs including Westminster, Camden, Islington, Tower Hamlets, Hackney, Southwark, and the City of London, our standard response time is 20 minutes. For outer London boroughs, response is typically within 30 minutes. We track every response electronically and provide monthly performance reports showing actual attendance times. If we fail to meet the guaranteed response time, your monthly retainer is reduced proportionately.
Our keys are stored at Ferguson House, our operations centre in Ilford, in a BS7558-approved key safe. BS7558 is the British Standard for key management systems used in security services. Our key safe is fire-rated, securely bolted, and monitored by CCTV 24/7. Each key set is allocated a unique reference number and stored in a tamper-evident seal. Only authorised officers can access keys, and every key withdrawal is logged electronically with officer ID, timestamp, and reason for withdrawal. You can request return of your keys at any time or arrange an annual audit where you attend our office to verify keys are present and correctly stored.
All officers who attend alarm activations are SIA-licensed in Security Guarding or Door Supervision and have undergone enhanced DBS checks. Officers are directly employed by Vigil — never agency staff or sub-contractors. This ensures accountability, adherence to our operational procedures, and consistency of service. Officers carry two-way radios connected to our control room, body-worn cameras for evidence capture, and torches for internal searches. If police attendance is required, officers remain on site until police arrive.
How our key holding and alarm response service works
Alarm activation → control room notified → officer dispatched → site attendance within guaranteed time → investigation and report.
Step 1 — Alarm activation: Your intruder alarm, fire alarm, or panic alarm activates. The alarm signal is transmitted to your alarm monitoring company (ARC), which in turn notifies our 24/7 control room via a secure communication link. If your alarm system has Redcare or CSL connection, the signal can be routed directly to Vigil, reducing notification time.
Step 2 — Dispatch and response: Our control room logs the activation, identifies the nearest available mobile patrol officer, and dispatches them immediately. The officer receives the alarm details via two-way radio or mobile data terminal, including site address, alarm type (intruder, fire, panic), floor plans, and any site-specific instructions. The officer drives to your premises using blue light exemption if the alarm is classified as urgent (e.g., panic alarm or confirmed intrusion).
Step 3 — External inspection: On arrival, the officer conducts a full external inspection of the premises perimeter, checking for signs of forced entry, broken windows, open doors, or suspicious activity. If forced entry is evident, the officer does not enter and immediately contacts police, remaining on site to secure the scene.
Step 4 — Internal search: If no external signs of intrusion are found, the officer uses our held keys to gain entry via the designated entry point. They disable the alarm using the code you provided during setup, then conduct a systematic search of the entire premises — floor by floor, room by room — to identify the cause of activation. The officer checks for intruders, open windows, damaged doors, environmental triggers (e.g., heating causing movement detectors to activate), or equipment faults.
Step 5 — Securing and reporting: If the premises are secure, the officer resets the alarm, ensures all entry points are locked, and leaves via the same designated route. Within 1 hour of leaving site, you receive a detailed attendance report via email or SMS, including time of arrival, cause of activation, actions taken, photographs of the site and alarm panel, and confirmation that the premises are secure. If remedial work is required (e.g., repairing a faulty sensor), the officer notes this in the report.
Types of alarms we respond to
Intruder alarms, fire alarms, panic alarms, and environmental monitoring systems.
Intruder alarms: The most common alarm type. Activated by movement detectors, door contacts, or glass-break sensors when unauthorised entry is detected. Our officers respond to all intruder alarm activations, investigate the cause, and contact police if evidence of intrusion is found.
Fire alarms: Activated by smoke detectors, heat sensors, or manual call points. Officers attend to determine whether the activation is genuine fire, false alarm, or equipment fault. If genuine fire or smoke is present, the officer evacuates the area and contacts the fire brigade immediately. Officers are trained in fire safety and understand the importance of not entering premises if fire is confirmed.
Panic alarms: Manually triggered by staff during an emergency such as robbery, assault, or medical incident. Panic alarms are treated as highest priority with immediate dispatch. Officers drive to site under emergency response protocols and contact police en route. If the premises are occupied, the officer provides assistance until emergency services arrive.
Environmental monitoring systems: Some clients have temperature, humidity, or flood detection sensors — particularly important for facilities storing temperature-sensitive stock, IT server rooms, or basements prone to flooding. Officers respond to environmental alarms, assess the situation, and take immediate action such as adjusting heating controls, isolating water leaks, or contacting your maintenance contractor.
Pricing and contract terms
Monthly retainer fee covering unlimited responses, with transparent pricing and no hidden fees.
Key holding and alarm response is charged as a fixed monthly retainer fee, which varies by location and required response time. The retainer covers unlimited alarm responses per month (subject to fair use — typically up to 10 responses per month). This pricing model provides certainty and protects you from escalating costs if you experience frequent false alarms.
For central London boroughs with 20-minute response times, the typical monthly retainer is £120–£180 plus VAT, depending on premises size and access complexity. For outer London boroughs with 30-minute response times, the retainer is typically £90–£140 plus VAT. If your premises require response times faster than 20 minutes (e.g., 15 minutes for high-risk retail stores), this can be arranged with a higher retainer fee.
There are no hidden fees. The monthly retainer covers key storage, 24/7 control room monitoring, officer dispatch, attendance, investigation, reporting, and key audits. If your alarm activates more than 10 times in a single month (indicating a persistent equipment fault), we may apply a supplementary charge of £40–£60 per additional attendance to encourage you to rectify the underlying issue. However, this is rare — most clients average 1–3 alarm activations per month.
Contracts are structured as rolling monthly agreements with 30 days' notice for termination. We do not impose long tie-ins or exit penalties. If you decide to change alarm response providers or manage alarm responses internally, simply provide 30 days' notice and we will return your keys securely.
Setting up key holding and alarm response
Key handover, alarm code provision, site walk-through, and go-live within 48 hours.
Step 1 — Site assessment: We conduct a free site visit to assess your premises, understand alarm system configuration, identify entry and exit routes, and discuss your response time requirements. This informs our quotation and service setup.
Step 2 — Contract agreement: We provide a written quotation specifying monthly retainer fee, response time guarantee, and service level agreement terms. Once you accept the quote, we issue a contract for signature.
Step 3 — Key handover and storage: You provide us with a spare set of keys to your premises. Keys are logged into our key management system with a unique reference number, placed in a tamper-evident seal, and stored in our BS7558-approved key safe. You receive written confirmation of key receipt and storage location.
Step 4 — Alarm code and contact details: You provide us with alarm panel disarm codes, alarm monitoring company contact details, and a list of nominated contacts to notify in the event of alarm activation. These details are stored securely in our control room system and are only accessible to authorised personnel.
Step 5 — Site walk-through: One of our officers conducts a site walk-through with you or your facilities manager to familiarise themselves with premises layout, alarm panel location, entry/exit routes, and any site-specific risks. The officer takes floor plans and photographs for our control room reference.
Step 6 — Go-live and testing: We coordinate with your alarm monitoring company to configure our contact details as the primary alarm response contact. Once this is complete, we conduct a test activation to confirm the control room receives the signal and dispatch procedures work correctly. The service is then live 24/7.
Insurance and compliance requirements
Vigil holds £10M public liability insurance and complies with police URN and NSI Gold standards.
Many commercial insurance policies require alarm systems to be monitored by an approved alarm receiving centre (ARC) and for alarm responses to be attended by an SIA-licensed keyholding company. This is particularly common for high-value stock, premises in high-crime areas, or businesses classified as elevated risk by insurers. Failure to maintain compliant alarm response can result in insurance claims being rejected or premiums being increased.
Vigil holds £10M public liability insurance and £10M employer's liability insurance, covering our officers' actions during alarm attendance. You are listed as an interested party on our insurance certificate, which is provided at contract signature and renewed annually. If your insurer requires specific evidence of alarm response compliance, we can provide attendance logs, performance reports, and confirmation of our SIA licensing and key storage standards.
We operate in compliance with Metropolitan Police Unique Reference Number (URN) protocols for alarm activation reporting. Officers log every attendance with a URN, which is provided to you in the attendance report. If police attendance is required, the URN allows you to reference the incident when communicating with insurers or during claims processing.
