LHC Procurement Group’s PB4 is a four-year public buildings framework for construction, refurbishment, civil infrastructure and facilities management. Announced on 3 November 2026 with a headline value of £2.34 billion, it gives eligible public bodies a route to procure individual projects from appointed contractors; it does not guarantee that the full value will be spent or that an appointed supplier will receive work. PB4 succeeds PB3 and is stated to run until 2 November 2030.
What is the LHC construction framework?
PB4 is an umbrella procurement agreement run by LHC Procurement Group. It sets a route and terms for public-sector clients to procure construction-related work from suppliers appointed to the framework. LHC describes the framework value as £2.34 billion. That is the announced value of the framework, not a pot paid to LHC, guaranteed public spending, or guaranteed turnover for any contractor.

The agreement establishes a pool of eligible suppliers and the conditions under which public bodies can place individual projects, known as call-offs. A council or other eligible client still needs to procure a specific project and contract with the supplier selected for that work.
PB4 succeeds LHC’s PB3 framework. Its announced scope brings together new-build construction, refurbishment, civil infrastructure and facilities management. LHC says the agreement covers England, Scotland and Wales, and its stated term is four years, ending on 2 November 2030. The precise opportunities available to a particular client or contractor depend on the applicable lot and current framework documents.

LHC’s PB4 launch announcement describes the agreement as a way to help public bodies address building needs across the asset lifecycle. A notable addition is a dedicated facilities-management workstream, intended to provide access to contractors for ongoing building sustainment as well as construction and refurbishment.
How does a framework agreement work?
A framework sets common conditions—such as scope, specification, quality, price and quantity—for contracts awarded during its term. Under LHC’s general explanation, frameworks normally run for four years. Suppliers compete to join; eligible public bodies can then use the framework to procure projects from the appointed supplier pool.

Clear out junk files and repair common Windows errorsFree Scan →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →In practical terms, there are two distinct stages:
- Framework competition: suppliers submit tenders and LHC assesses them for appointment to relevant lots. Appointment makes a supplier eligible for subsequent opportunities under those lots.
- Project call-off: a public body procures a particular project under the framework terms and selects an appointed supplier. The client and the supplier carrying out the work enter the project contract directly.
Being appointed can give a contractor access to a public procurement route, but it does not place an order or promise a minimum amount of work. Likewise, the £2.34 billion headline should not be read as an amount already committed to projects. It is the value LHC announced for the framework, while actual project awards arise separately through call-offs.
LHC says it supports the client’s call-off process with procurement and technical advice, management of expressions of interest, and price verification. That support does not make LHC the works contractor: the public client contracts directly with the appointed company delivering the project. Read LHC’s framework agreement explanation for its general description of how frameworks operate.
What work does PB4 cover?
LHC’s announcement groups the framework’s work into four broad areas. The exact scope, lot structure and call-off conditions for a particular opportunity should be confirmed in the current procurement documents, rather than inferred from the headline categories.

- New build: construction of new public buildings or other assets within the framework’s stated scope.
- Refurbishment: work to improve or renew existing buildings, including public-building and social-housing projects covered by the relevant lot.
- Civil infrastructure: infrastructure work included within PB4’s construction scope.
- Facilities management: a dedicated workstream for ongoing building sustainment. Its inclusion extends the framework’s stated reach beyond delivering a new or refurbished building to supporting assets over time.
The facilities-management addition is particularly relevant where the client’s need continues after construction or refurbishment. LHC director of product innovation Graham Collie said public bodies are dealing with ageing assets, maintenance pressures and stringent safety and regulatory requirements, and that PB4 was designed to help clients access competent contractors beyond the point a building is completed or refurbished. That is LHC’s explanation of the framework’s purpose, not a guarantee of any particular service outcome.
Who can use PB4?
LHC says its frameworks are free to use for local authorities, social landlords and other public-sector bodies procuring works, products or services for construction, refurbishment and maintenance of social housing and public buildings. LHC identifies its group coverage as England, Scotland and Wales, consistent with PB4’s launch announcement.
Those broad statements do not establish that every public body can access every PB4 opportunity. A client should confirm its eligibility and the relevant lot access in the current procurement documents before relying on the framework for a project. The same caution applies to geography: a framework’s overall regional coverage does not, by itself, confirm the availability of a particular supplier or lot in every location.
How can a contractor become an appointed supplier?
A supplier has to win appointment through a competitive tender. LHC says opportunities are advertised through Find a Tender, Public Contracts Scotland, Sell2Wales and its InTend e-tendering portal. The tender package typically includes an Invitation to Tender, an Offer Document containing technical-quality questions and pricing templates, and the framework terms and conditions. LHC says suppliers usually have at least a month to prepare and submit a bid; the timetable for a specific competition is set out in its notice and tender documents.
Supplier qualification covers more than the price of the work. LHC says its tender process asks about areas including:

LHC says it evaluates qualitative, technical, sustainability and price criteria using a Most Economically Advantageous Tender (MEAT) approach, then ranks bids by value-for-money score. The strongest-scoring bids are not simply the lowest prices: the stated assessment includes quality and sustainability alongside cost. LHC says it typically appoints three or four of the top-scoring suppliers to each regional lot, depending on likely demand and other considerations. That is a general description of its process, not a PB4-specific count for every lot.
To prepare a bid, a contractor should first identify the opportunity and lot that match its work, locations and capacity. It should then use the actual ITT and Offer Document to map each response to the scored requirements, complete the pricing template as instructed, and check that evidence supports claims about capability, quality, safety, sustainability and relevant public-sector experience. Tender wording and requirements vary by competition, so the live documents—not a general summary—control what must be submitted.
What does PB4 mean for suppliers and councils in practice?
For a contractor, appointment is an opportunity to compete for project work through a defined public-sector route, not a guaranteed pipeline. LHC’s launch announcement says 155 contractors have been appointed across PB4 and that 75% of its approved suppliers are SMEs. These are framework-wide figures; they do not mean that 155 suppliers are available in each lot, nor do they indicate how much work any one supplier will win.
For a council or other public client, the framework can provide access to appointed contractors under agreed conditions and a route supported by LHC’s procurement and technical assistance. The client still needs to define its project requirement, confirm it can use the relevant lot, follow the applicable call-off procedure and establish the project contract with the selected supplier. PB4 is therefore a procurement mechanism, not a substitute for defining the work or managing the resulting contract.
Both sides should think in terms of the particular project and lot, not just the size of the overall framework. Relevant questions include whether the supplier’s capability and geographical reach fit the requirement, whether the work sits within the lot’s scope, what selection process applies at call-off, and how price, quality, sustainability and social-value commitments are addressed. The available high-level announcement does not set out every lot’s value, supplier roster or project-level award method; the current framework guide and procurement documents are the sources to consult for those details.

How does social value fit into PB4?
LHC describes itself as a not-for-profit and says excess revenue generated through levy income is rebated to clients based on project invoice value, typically for local community social-value projects. For PB4, LHC says a portion of surpluses goes through its Community Benefit Fund and partner charities Lintel Trust and Lifting Lives into local communities and initiatives.
This should not be confused with a promise that the full value of a project—or all framework revenue—is redistributed. LHC’s statement concerns a portion of surpluses and its described rebate approach. Separately, suppliers’ sustainability and social-value credentials may be relevant to the tender evaluation; LHC says qualitative, technical, sustainable and price criteria contribute to its MEAT assessment. Graham Collie’s colleague Michael McLaughlin, LHC’s head of social value, said regional teams can support clients and suppliers in demonstrating wider benefits beyond specific works. The exact requirements for any bid or project are determined by its documents.
What should you check before relying on a headline figure?
The £2.34 billion figure is useful as an indication of the announced scale of PB4, but it should always be described as the framework’s announced value. It is not a guarantee that public bodies will spend that sum, a payment to LHC, or revenue promised to appointed contractors. A supplier’s appointment is likewise not a project award; work depends on later call-offs and the applicable procurement process.
For decisions about a live opportunity, verify the current tender or framework guide. In particular, check the workstream and lot scope, geographical availability, eligible client status, appointed supplier pool, call-off rules, evaluation requirements and applicable terms. The launch announcement confirms the overall scope, term and supplier totals, but those headline facts should not be used to guess the details of an individual lot or contract.

Frequently Asked Questions
Does the £2.34 billion PB4 value mean that amount will be spent each year?
No annual spending commitment is established by the headline figure. LHC describes £2.34 billion as the framework value, while project spending depends on separate client call-offs during the agreement term.
Is PB4 a grant that councils apply to for construction money?
No. PB4 is a procurement framework, not a grant fund. It provides terms and an eligible supplier route for public bodies to procure individual projects.
