How Security Firms Win UK Public Sector Guarding Tenders

Security work surfaces across several layers of portal, and the contract value decides which layer. Higher-value framework competitions and large guarding contracts must be advertised on Find a Tender, the UK central platform for regulated procurement. From January 2026 the services thresholds are £139,688 for central government and £215,720 for sub-central buyers such as councils, NHS trusts, and universities, calculated inclusive of VAT. Smaller guarding contracts, single-site cover, and lower-value lots are advertised on Contracts Finder, which lists public contracts above £12,000 and which from April 2026 is being replaced by the Central Digital Platform as the primary notice service under the Procurement Act 2023.

Scotland, Wales, and Northern Ireland run their own systems, so a guarding contract for a Glasgow health board or a Cardiff council may never reach the main UK feeds. Those notices sit on Public Contracts Scotland, Sell2Wales, and eSourcing NI instead. The buyers span the whole public estate: central departments, local authorities, NHS trusts, universities, schools, police and fire services, social housing, and transport bodies. Each can publish on a different portal, which is why checking by hand quietly leaks opportunities. If you are unsure which platform carries which work, the split between Find a Tender and Contracts Finder is the place to start.

Before price matters, a public buyer checks that you are allowed to do the work and approved to a recognised standard. Frontline staff carrying out licensable activities, which include security guarding, door supervision, public space CCTV surveillance, close protection, cash and valuables in transit, and key holding, must each hold an individual licence from the Security Industry Authority, the regulator created under the Private Security Industry Act 2001. That is the floor, not a differentiator, because every compliant competitor meets it.

The real gate is the SIA Approved Contractor Scheme. ACS is a voluntary, company-level approval that the SIA grants for three years with surveillance assessments in between, and public buyers very often make it a pass or fail requirement or weight it heavily in scoring, so a firm without it is frequently filtered out before evaluation. The SIA has confirmed it is redesigning the scheme to be more capability driven, partly in response to the changing threat picture and Martyn's Law, so the bar is rising rather than falling. For a bidder the lesson is simple: hold ACS, keep your assessment current, and target the competitions where it is required, because those are the ones your unapproved rivals cannot enter.

A large share of public security work never reaches an open tender. It flows through framework agreements where buyers run a mini-competition or direct award among pre-approved suppliers, so if you are not on the relevant framework you do not see the call-off at all. The dominant route is now RM6378 Facilities Management and Security Services, the Crown Commercial Service agreement launched in November 2024 and running to 2034, which the buying authority confirms replaced the previous RM6232 facilities management framework and RM6257 security framework. RM6378 carries the security and guarding scope alongside facilities management, with value bands set around £2 million to reflect that smaller contracts run on different economics.

The security scope inside RM6378 covers manned guarding and patrol, meaning static officers, mobile patrols, gatehouse and reception cover, and surveillance monitoring, plus technical security such as CCTV and access control installation and security consultancy. It is not the only route. NHS bodies buy through their own public sector frameworks and shared business services, and regional hubs such as YPO, ESPO, and Pagabo run security and FM agreements that councils and schools call off from. Because a missed qualification window can lock you out for the whole term, watching framework refresh dates matters as much as watching individual notices.

Manned guarding is labour intensive and tied to a fixed site, which makes it the clearest case for TUPE. When a public buyer re-tenders a guarding contract and a new supplier takes over, the officers assigned to that site form an organised grouping of employees, so under the service provision change rules in the Transfer of Undertakings (Protection of Employment) Regulations 2006 they transfer to the incoming contractor on their existing terms. You inherit the team, their pay, their length of service, and their employment rights, and you cannot lawfully cut those terms simply because of the transfer.

This reshapes how a guarding bid is actually won. You are not pricing a blank sheet of labour, you are pricing an existing workforce you will take on, so a bid built on undercutting wages is usually neither lawful nor deliverable. The credible levers are mobilisation, vetting, supervision, technology, and management uplift, not a lower hourly rate. The honesty point that follows is worth stating plainly: winning the contract is a mobilisation and management challenge as much as a pricing one, and the firms that bid this way tend to hold contracts longer. Reading the incumbent terms early, which the tender pack usually discloses, is what lets you make a realistic bid or no-bid decision before you commit.

Public security tenders score heavily on assurance, and three things come up again and again. The first is recognised standards: buyers expect compliance with BS 7499 for static guarding and mobile patrol services and BS 7858 for the security screening and vetting of staff, usually evidenced through certification by an accredited inspectorate such as the National Security Inspectorate or SSAIB, the same bodies that assess firms for the SIA scheme. The second is vetting itself, because guards often work in schools, hospitals, and sensitive sites, so DBS checks and BS 7858 screening records have to be in place and auditable.

The third is pay. Many public buyers now require the Real Living Wage or, in the capital, the London Living Wage, and they assess social value alongside price, which rewards local employment, training, and fair conditions rather than the lowest bid. Combined with the TUPE workforce you inherit, this means margins on guarding are thin and won on quality, not undercutting. Demand, meanwhile, is rising: Martyn's Law, the Terrorism (Protection of Premises) Act 2025, is pushing qualifying public venues to put proportionate security measures in place over its implementation period, which feeds new guarding and stewarding requirements into the public pipeline.

The hardest part of monitoring is noise. A large authority publishes hundreds of unrelated notices for every guarding contract worth your time, so precise filtering is what makes alerts usable. Keywords are the first lever: terms like manned guarding, security officer, mobile patrol, static guard, gatehouse, key holding, concierge, CCTV monitoring, and stewarding. The catch is that buyers describe the same need in different words, so a literal keyword for guarding can miss a notice headed security services or provision of a manned response, and concierge, front of house, and reception security all point at related work.

CPV codes give a more structured filter. The most useful for this sector are 79710000 (security services), 79713000 (guard services), 79714000 (surveillance services), 79715000 (patrol services), and 79711000 (alarm-monitoring services), with 35120000 and 32235000 covering CCTV and electronic security systems where you also install. Combine codes with region filters so you only see work inside your operating area, and add disqualifier keywords to drop sectors you never serve. Done well, this turns a flood of public notices into a short, relevant list, which is the same discipline behind effective tender monitoring in any sector and the reason monitoring tools earn their place.

No single portal shows you all the public sector security work, and checking Find a Tender, Contracts Finder, the devolved sites, and the framework operators by hand is the task that slips when a bid team is busy writing. Jorpex closes that gap by monitoring 50+ public procurement sources at once and matching each notice against your profile, so manned guarding, mobile patrol, key holding, and CCTV monitoring opportunities arrive in one filterable stream rather than scattered across logins.

The matching is semantic, not literal, which matters in security where the same job appears as guarding, manned response, security officer cover, or front of house. Embedding-based matching catches those variants, and 17-language support helps firms that also bid in Ireland or across Europe, while disqualifier filters strip out the sectors and geographies you never pursue. Matches land in Slack, Microsoft Teams, or email as realtime, daily, or weekly automated tender alerts, each carrying the deadline and value so your team can move fast. Plans start at $49 per month (Starter) and $149 per month (Pro) with a 14-day free trial, no per-user fees, and up to 5 notification profiles on Pro so a guarding desk and an electronic security desk can each watch their own work. Jorpex surfaces the framework and contract opportunities that put you in the running. It does not submit bids, hold your SIA approval, or replace registration on the buyer and framework portals, but it makes sure you never miss the notice. See how it compares with other tender alert services, and how smaller firms use it to compete with national guarding providers, alongside the wider UK public sector tendering picture.
