What Is Key Holding and Alarm Response?
Key holding and alarm response (KHAR) is one of the most popular and profitable services offered by UK security companies. In simple terms, your company holds keys to a client’s premises and responds when their alarm is triggered — attending the site, investigating the cause, and taking appropriate action.
For clients, it means they don’t have to drag themselves out of bed at 3am when a faulty sensor triggers an alarm. For security companies, it’s a recurring revenue stream with relatively low operational costs once the infrastructure is in place.
Why KHAR Is Good Business
Key holding offers several commercial advantages:
- Recurring monthly revenue — clients pay a retainer whether or not alarms activate
- Low staffing overhead — guards handle responses alongside mobile patrol duties
- High client retention — once a client trusts you with their keys, switching providers is inconvenient
- Upsell opportunities — KHAR clients often add static guarding, CCTV monitoring, or patrol services
- Scalable — each additional client adds marginal cost but full monthly revenue
Operational Requirements
Key Management
Secure key management is non-negotiable. You need:
- A secure key safe or cabinet with restricted access
- Unique key identifiers (never labelled with the client’s address)
- A key register tracking which keys are held for which client
- Sign-out procedures when keys are taken for a response
- Regular audits confirming all keys are accounted for
Response Time SLAs
Most KHAR contracts specify a maximum response time, typically 20-60 minutes depending on the area. You need to be confident you can meet these SLAs consistently. This means:
- Understanding your geographic coverage area realistically
- Having guards positioned to respond within SLA times
- Tracking actual response times to demonstrate compliance
- Being honest with clients about areas you can’t reliably cover
Response Procedures
Guards responding to alarm activations need clear procedures:
- Approach the premises observing for signs of forced entry
- Do not enter if there’s evidence of an intruder still present — call police
- If safe to enter, conduct a systematic search of the premises
- Identify and document the alarm cause (intruder, environmental, fault)
- Reset the alarm if appropriate
- Secure the premises and report to the client
- File a detailed response report
Documentation and Reporting
Every alarm response must be documented, including:
- Time of alarm notification
- Time of arrival on site
- Findings (cause of activation, any damage or intrusion)
- Actions taken
- Time premises were secured
- Photos of any relevant findings
This documentation protects your company and provides the client with evidence of your response.
Insurance and Licensing
KHAR operations require:
- SIA licensing — all responding guards must hold a valid SIA licence
- Professional indemnity insurance — covering your liability while holding client keys
- Public liability insurance — covering your activities on client premises
- Keyholder insurance — specific cover for loss of or damage to held keys
Technology for KHAR Operations
Efficient KHAR operations benefit from:
- GPS tracking showing which guard is nearest to the alarming site
- Digital response reports filed from the guard’s phone on site
- Automated response time tracking against SLA commitments
- Client portal access so clients can see response reports directly
TacDesk supports key holding operations with GPS tracking, instant mobile reporting, and client portal access for response transparency. Try the demo to see how it works for alarm response management.
