Security Services Tenders in the UK

TenderSignal is the UK's most complete source of live security services tenders.

We aggregate security procurement from 145+ portals — councils, NHS trusts, schools, universities, housing associations, MOD, police forces, fire services, central-government departments, ALBs and major private estates. Coverage spans manned guarding, mobile patrol, CCTV monitoring, key holding, event security, and cyber-physical converged security operations.

Whether you're a sole-trader SIA-licensed mobile patrol operator, an SME guarding firm bidding for a council framework, or a major national security provider chasing government-wide contracts, TenderSignal surfaces opportunities daily. Sub-sectors include manned guarding, mobile patrol, alarm response, CCTV monitoring, locksmith services, and electronic security installation.

Security contracts typically run 3–5 years. Pro users see expiring-contract alerts — vital for security where incumbency knowledge and TUPE management are decisive in re-tender bids.

Security Services Procurement in the UK

UK public-sector security spend exceeds £3bn annually, spread across central government (FCO, MOD, Cabinet Office), NHS trusts, councils, schools, universities and housing associations. The Procurement Act 2023 governs services above £213,477; below that, councils typically use approved-supplier lists or YPO/ESPO framework call-offs.

Key frameworks include CCS Linked Services (which absorbs some security categories), NHS SBS Hard FM (includes security), Procurement for Housing's security framework, NEPO, YPO and ESPO regional security frameworks. For central government and high-classification sites, Cabinet Office security framework and MOD-specific routes apply.

Notable drivers include Martyn's Law (Protect Duty) commencement, hostile-vehicle mitigation requirements at public venues, increased school and NHS site-security spend post-incident, and the wider convergence of physical and cyber security in public estates.

How to Win Security Tenders

Security procurement uses PQQ + ITT, with quality typically scored 60% — covering operational plan, officer recruitment and retention, supervisor coverage, technology (body-worn video, incident reporting), training, social value and TUPE handling. Price weighting is higher than in consulting because operating costs are well-understood.

SIA Approved Contractor Scheme (SIA ACS) is essentially mandatory for public guarding contracts. ISO 9001/14001/45001 and BS 7858 (security screening) are widely required. For high-classification work, supplier and personnel security clearance (SC, CTC or DV) and JOSCAR are needed. NSI or SSAIB accreditation for electronic security installations.

Common pitfalls: under-priced bids that don't survive Real Living Wage and supervisor-cover analysis, weak officer-retention plans (industry attrition is high), poor TUPE handling that risks losing experienced incumbent staff, and missing site-specific risk assessment. Strong bids show realistic pay rates, supervisor ratios, named contract managers, and credible technology investment.

Security Services tenders: frequently asked questions

How do I find security tenders in my region?

TenderSignal lets you filter by council, NHS trust, housing association or specific site. Security is highly geography-dependent — set your delivery footprint during onboarding to see only the manned guarding, mobile patrol and CCTV contracts you can actually deliver.

What is the average value of a UK security tender?

Single-site guarding contracts typically £100k–£500k per year. Multi-site frameworks £500k–£5m per year. Major NHS trust or central-government estate contracts can exceed £10m. Mobile patrol and key holding contracts often £50k–£250k per year.

Do I need to be on a framework to bid for security work?

Not always — councils still run direct ITTs for site-specific work. But for multi-site contracts, CCS Linked Services, NHS SBS Hard FM, and YPO/ESPO regional security frameworks dominate. Framework membership also lifts your visibility to procurement teams.

How often are security tenders published?

TenderSignal ingests around 75–150 security opportunities per week. Volume rises around school summer holidays (academic year re-tenders) and at financial year-end as councils consolidate spend.

What qualifications do I need to bid for security contracts?

SIA Approved Contractor Scheme (essential for guarding); BS 7858 security screening; ISO 9001, 14001, 45001 universally. For electronic security: NSI Gold or SSAIB approval. For high-classification work: JOSCAR, SC/CTC/DV clearance, Cyber Essentials Plus. Real Living Wage Employer status increasingly valued.

Can small businesses win security tenders?

Yes — single-site contracts and mobile-patrol packages are well-suited to SMEs. Councils often lot multi-site frameworks by area to widen SME access. The Procurement Act 2023's lotting requirements help further, particularly for council and housing-association work.

What is the procurement threshold for security contracts?

Services above £213,477 (central government) or £164,176 (sub-central) must be advertised on Find a Tender. Below threshold, councils use mini-competitions, dynamic purchasing systems or approved-supplier lists. Most single-site guarding contracts fall under the threshold.

How does Martyn's Law (Protect Duty) affect security tenders?

The Terrorism (Protection of Premises) Act 2025 — Martyn's Law — introduced new duties on venues to prepare for terrorist attacks. Public-sector estates are reviewing security provision and TenderSignal Pro users see PIN notices for the resulting procurements as venues update their security arrangements.
