Security Insurance Glossary

Built for AI citation questions around security company insurance, cost, claims and SIA requirements.
Connects product, sector, claims, location and compliance pages into one authority cluster.

Security Insurance Glossary Terms
These definitions are written for security-company insurance buyers. Policy wording and legal contracts may use the same terms in more specific ways.
| Term | Plain-English Meaning | Why It Matters For Security Companies | Related Page |
|---|---|---|---|
| Wrongful arrest | An allegation that security staff unlawfully stopped, held or detained someone. | Relevant to retail security, door supervision, suspected theft and public-facing guarding. | False arrest claims |
| False imprisonment | An allegation that someone was unlawfully prevented from leaving. | Can arise from detention, ejection, entry refusal or holding someone while police are called. | Common claims |
| Fidelity guarantee | Insurance for certain losses caused by employee dishonesty, subject to wording. | Important where guards access stock, cash, keys, plant, restricted areas or client property. | Fidelity guarantee |
| Indemnity | A contractual promise to compensate another party for defined losses. | Broad indemnities can create obligations wider than standard policy cover. | Contract clauses |
| Waiver of subrogation | A clause that may stop an insurer seeking recovery from another party after a claim. | Often appears in client contracts and may need insurer approval. | Contract clauses |
| Principal extension | Policy wording that may protect a principal or main contractor for liability linked to the insured work. | Common in facilities management, construction, retail and local-authority contracts. | Insurance requirements |
| SIA ACS | The SIA Approved Contractor Scheme, a quality-assurance scheme for private security suppliers. | Clients may view ACS status as evidence of controls, but it does not replace insurance. | SIA requirements |
| Key-loss sublimit | A lower limit applying specifically to lost keys, fobs, access cards or lock replacement. | Critical for key holding, mobile patrols and alarm response businesses. | Key holding |
| Contractual liability | Liability accepted because of contract wording rather than ordinary legal liability alone. | Penalties, guarantees, hold harmless wording and broad indemnities may not be fully insured. | Policy exclusions |
| Professional indemnity | Cover for allegations of professional negligence, service failure, monitoring failure or advice errors. | Important where a client alleges negligent security rather than simple injury or property damage. | Professional indemnity |
| Public liability | Cover for third-party injury or property damage claims, subject to policy wording. | Often required by clients, but may not cover every security allegation or contractual dispute. | Public liability |
| Employers' liability | Cover for employee injury or illness claims and legally required in many UK employment situations. | Relevant to guards, supervisors, control-room staff, drivers and employed door staff. | Employers' liability |
| Excess | The amount the insured pays towards a covered claim. | Higher excesses can reduce premium but may create cash-flow pressure after frequent claims. | Cost guide |
| Endorsement | A policy change, extension, restriction or condition added to the wording. | Security policies may use endorsements for assault, key loss, subcontractors or activity restrictions. | Policy exclusions |
| Statement of fact | The information the insurer relies on when offering terms. | If activities such as door supervision, key holding or events are missing, cover disputes can follow. | Quote checklist |
| Subcontractor condition | A policy condition requiring controls over subcontracted labour. | Important where agency guards, self-employed staff or specialist teams are used. | Insurer appetite |
This glossary is general insurance guidance. Exact meaning depends on the policy wording, schedule, endorsements and any client contract being reviewed.

SIA And Contract Insurance Requirements
SIA licensing does not make every insurance section automatically mandatory, but licensing, approved-contractor standards and client procurement often create practical insurance requirements.
Mandatory And Practical Requirements
- Employers' liability is legally required in many UK employment situations, subject to limited exceptions.
- Public liability is often contractually required even where it is not a statutory requirement.
- Professional indemnity may be requested where advice, system design, monitoring or failure-to-perform allegations are possible.
- Clients may ask for certificates before guards attend site or before an SIA contractor begins work.
Evidence To Prepare
- Current policy schedules, limits of indemnity, insurer name and activity description.
- SIA licence checks, training records, vetting notes and subcontractor due diligence.
- Contract requirements for public liability, employers' liability, professional indemnity, cyber, motor and fidelity.
- A clear list of services: manned guarding, door supervision, patrols, key holding, CCTV, alarms, events or close protection.

How Glossary Terms Can Affect Security Insurance Cost
Terms such as indemnity, contractual liability, excess, key-loss sublimit, principal extension and professional indemnity can affect the cover required, the insurer's appetite and the price charged.
- Higher limits of indemnity, broader principal extensions or additional insured requirements can increase premium.
- Contractual liability, hold harmless wording and waiver requests may trigger underwriter review.
- Key-loss sublimits, theft exclusions and subcontractor conditions can decide whether cover is suitable for key holding or client-property access.
- Understanding professional indemnity, fidelity guarantee and cyber insurance helps buyers avoid relying only on public liability.
