Transport for London has published an award notice for physical security guarding and reception services across its estate, naming Mitie Security Limited as the supplier with an award value of £237 million over five years. The notice appeared on Contracts Finder, the UK government's public register of contract notices, on Monday 12 October.
What the notice says
The notice, procurement reference CW92521, describes the work as "Supply of Security related services across TfL". It names one supplier, Mitie Security Limited (Companies House number 01013210), with an award value of £237,000,000. The contract runs from 26 July 2026 to 25 July 2031, and the award date is given as 21 July 2026, so the notice, published in October, records an award made in July.
TfL let the contract under the competitive procedure with negotiation, above the procurement threshold. It marked the contract as not suitable for small and medium-sized businesses or voluntary sector organisations, and records Mitie as not an SME. A redacted copy of the signed contract is attached to the notice.
What it does not say
The notice gives two different figures. Alongside the £237,000,000 award value, the "Value of contract" field in the contract summary shows £123,367,606. The notice does not explain the difference, and we have not assumed a reason. The notice also does not give staff numbers, the stations or sites covered, or how many firms bid.
What it means for operators
These are Ops Con planning points. A contract of this size is likely to shape a large share of transport-network guarding work in London for five years, and its guarding element will be delivered by SIA-licensed officers employed by, or subcontracted to, the prime contractor. TfL's own flag that the contract is not suited to smaller firms means the main route in for independent operators is through the supplier rather than the buyer.
For security firms tracking public-sector work, Contracts Finder award notices like this one are a free, primary record of who won what, for how much and for how long. They are also an early sign of when the next round of large guarding contracts will come back to market.
