LHC Procurement Group has named 119 firms on its new Public Buildings Construction and Infrastructure framework, PB4.
The official contract award notice gives the framework a maximum value of £1.95 billion excluding VAT across ten lots. It covers new-build public buildings, refurbishment, civil infrastructure and hard facilities management.
The estimated contract period runs from 16 October 2026 to 15 October 2030, with an option to extend to 15 October 2031. The award decision was made on 2 October 2026 and the standstill period ends on 15 October.
For specialist subcontractors, the important part is not simply that another large framework has been awarded. It is knowing which contractors now have a route to the work, what types of projects sit underneath the framework and who you should be building relationships with before individual projects are called off.
The short version: PB4 is not £1.95bn of work already handed to contractors. It is a procurement route through which eligible public bodies can award qualifying projects. For subcontractors, the appointed supplier lists are a four-year prospecting map.
What is the LHC PB4 framework?
PB4 is LHC Procurement Group's latest framework for the construction, refurbishment and management of public buildings and associated infrastructure.
The scope includes:
- new public buildings using traditional or framed and panelised construction systems;
- refurbishment and restoration of existing buildings, including listed buildings;
- civil infrastructure such as highways, sewers and drainage;
- demolition, recovery and other site-preparation work;
- hard facilities management covering building fabric, mechanical and electrical systems, fire safety and other technical services; and
- associated professional services, including project management and cost control.
Eligible users include local authorities, social landlords, NHS bodies, police and fire services, publicly funded schools, colleges, universities, defence organisations, registered charities and other contracting authorities across the UK.
An appointment to PB4 does not mean a contractor has automatically been awarded a share of £1.95bn. The notice states that framework lot values may be shared with other lots. Individual projects still need to be called off under the framework's rules.
How is PB4 divided?
The framework contains ten lots:
| Lot | Workstream | Appointed suppliers |
|---|---|---|
| 1 | New Build Only: £0–£1m | 55 |
| 2 | New Build Only: £1m–£2.5m | 54 |
| 3 | Refurbishment Only: £0–£1m | 67 |
| 4 | Refurbishment Only: £1m–£2.5m | 62 |
| 5 | Civil Infrastructure: £0–£2.5m | 23 |
| 6 | Civil Infrastructure: over £2.5m | 17 |
| 7 | New Build, Refurbishment and Associated Services: £2.5m–£10m | 42 |
| 8 | New Build, Refurbishment and Associated Services: £10m–£25m | 25 |
| 9 | New Build, Refurbishment and Associated Services: over £25m | 20 |
| 10 | Hard Facilities Management: all values | 17 |
These figures are appointments by lot, not unique companies. Many contractors appear on several lots; the award notice names 119 distinct suppliers across the framework as a whole.
The larger construction lots are particularly relevant for subcontractors looking to enter the supply chains of established regional and national main contractors.
Which contractors won the £25m-plus PB4 lot?
Twenty contractors have been appointed to Lot 9, covering new build, refurbishment and associated projects worth more than £25m:
- Baxall Construction Limited
- C G Fry and Son Ltd
- Classic Builders (South West) Limited
- E.W. Beard Limited
- Farrans Limited
- Galliford Try Construction Limited
- GMI Construction Group PLC
- Guildmore Ltd
- Heron Bros. Limited
- Kier Construction Limited
- Kori Construction Limited
- McPhillips (Wellington) Limited
- Morgan Sindall Construction & Infrastructure Ltd
- MY Contracts Limited
- Neilcott Construction Limited
- Procast Building Contractors Ltd
- Robertson Construction Group Limited
- Tilbury Douglas Construction Limited
- Tom Prichard Contracting Limited
- Willmott Dixon Construction Limited
That list is taken directly from the published award notice, rather than reconstructed from procurement aggregators. This matters because shortened trading names and legal entity names can otherwise make the same supplier look like two different businesses.
Who is on the £10m–£25m lot?
Lot 8 has 25 appointed contractors:
- Ashleigh (Scotland) Limited
- Baxall Construction Limited
- C. Wynne & Sons Limited
- Clark Contracts Limited
- Devon Contractors Limited
- E.W. Beard Limited
- Esh Construction Limited
- Farrans Limited
- G.F. Tomlinson Building Limited
- Galliford Try Construction Limited
- GMI Construction Group PLC
- Guildmore Ltd
- Heron Bros. Limited
- Kier Construction Limited
- Kori Construction Limited
- McLaughlin & Harvey Limited
- McPhillips (Wellington) Limited
- Morgan Sindall Construction & Infrastructure Ltd
- MY Contracts Limited
- Neilcott Construction Limited
- Quinn (London) Limited
- T & B (Contractors) Limited
- Tilbury Douglas Construction Limited
- Tom Prichard Contracting Limited
- Willmott Dixon Construction Limited
This band contains a useful mix of national names and regional contractors. A subcontractor should not assume that the largest brand is automatically the best target: geography, package size and the contractor's existing supplier base matter more.
£2.5m–£10m building work
The biggest contractor pool among the three combined building-work lots sits within Lot 7, covering new build, refurbishment and associated work valued between £2.5m and £10m.
A total of 42 contractors were appointed. The list ranges from major contractors including Kier, Galliford Try, Morgan Sindall, Tilbury Douglas, Vinci and Willmott Dixon to regional businesses such as Alcema, C. Wynne & Sons, E. Manton, G.F. Tomlinson, Logan Construction, Pave-Aways and Willis Construction.
For a specialist subcontractor that does not need or want to chase only Tier 1 firms, this lot may provide the more useful account list. The package values, buying structures and regional coverage of these contractors may be a closer match to the work your business can deliver.
Civil infrastructure contractors
PB4 also contains two civil infrastructure lots:
- Lot 5: £0–£2.5m — 23 appointed suppliers.
- Lot 6: over £2.5m — 17 appointed suppliers.
The 17 contractors on Lot 6 are:
- Akela Construction Limited
- Amalgamated Construction Ltd
- Ashleigh (Scotland) Limited
- Bartlett Contractors Limited
- BRM Utility Services Ltd
- CHAP Group Ltd
- CK Rail Solutions Ltd
- Corserv Solutions Limited
- Enable Infrastructure Limited
- Galliford Try Construction Limited
- Jackson Civil Engineering Ltd
- Luddon Construction Limited
- McPhillips (Wellington) Limited
- Montel Civil Engineering Limited
- P. Casey (Land Reclamation) Limited
- Tom Prichard Contracting Limited
- Vectorex Construction Limited
Lot 5 adds Aspire Construction Projects, Ateb Groundworks, Compass Building and Construction Services, G. Simpson (Builders), GMR Henderson Builders and M & J Group (Construction & Roofing) to that pool.
The civil scope includes demolition and site preparation, highways, drainage, sewers and infrastructure associated with public-building projects.
What does the PB4 award mean for subcontractors?
If you are a specialist subcontractor, you are not trying to become retrospectively appointed to PB4 now that the framework competition has finished.
The opportunity is to identify the appointed main contractors whose future PB4 projects are likely to require your trade. That could include businesses delivering:
- groundworks, drainage and structural works;
- roofing, cladding and brickwork;
- doors, windows, decorating and flooring;
- fire protection and passive fire work;
- M&E, electrical works and HVAC;
- fit-out and refurbishment;
- demolition and site preparation;
- landscaping; or
- access and specialist plant.
Not every appointed contractor will need every trade, and an appointment does not mean a live subcontract package exists today. But it gives you a better starting point than prospecting randomly: these contractors have secured a procurement route capable of producing work for the next four years.
Do not wait for the subcontract tender to appear
Many subcontractors wait until a package appears on a tender portal or lands in their inbox. By that point, the main contractor may already have several businesses it knows, has used before or has prequalified.
A better approach is to work backwards.
1. Identify the relevant PB4 contractors
Start with contractors appointed to the value bands and regions that match your normal projects.
If you typically deliver £100,000 packages, chasing every national contractor on the £25m-plus lot may not be the best use of your time. A strong regional contractor in the £2.5m–£10m band could be considerably more valuable.
2. Find the people responsible for your route in
Depending on the contractor and trade, that could include:
- procurement and supply-chain managers;
- estimators and quantity surveyors;
- commercial managers;
- project managers and pre-construction teams; or
- regional directors.
The objective is not to collect hundreds of names. It is to understand who influences the appointment of your type of subcontractor.
3. Check their supplier requirements
Before contacting them, establish whether the contractor uses approved supplier lists, prequalification questionnaires, procurement portals, preferred subcontractor databases, regional supply-chain teams or project-specific tender lists.
Our guide to getting onto a construction company's approved contractor list covers this process in more detail.
4. Give them a reason to remember you
“We are a subcontractor and would love to tender for your projects” does not give a buyer much to work with.
Show the things that make someone comfortable putting you onto a tender list:
- relevant completed projects;
- geographical coverage and package values;
- accreditations and specialist capabilities;
- technical knowledge; and
- evidence of solving the problems their projects create.
The aim is familiarity before the package is live.
5. Track the relationship
A framework like PB4 runs for years. A procurement manager saying “speak to our regional commercial team” is useful intelligence. So is learning:
- which portal the contractor uses;
- when it reviews suppliers;
- which regions need coverage;
- whether procurement is central or project-specific;
- which team manages your trade; and
- which upcoming schemes may need your capability.
Record that information. It compounds.
Why PB4 matters beyond the award announcement
The easiest time to talk about a framework is the day the winners are announced. The most useful time to act on it may be months later.
PB4 is expected to operate until October 2030, with a possible 12-month extension. Eligible public bodies can use the appointed contractors for qualifying projects throughout that period.
That means the contractor list should not be treated as one day's construction news. It is effectively a prospecting map.
For a specialist contractor, the useful questions are:
- Which appointed businesses buy what we sell?
- Which value bands and regions fit our delivery model?
- Who controls the relevant supply chain?
- What must we demonstrate before they will invite us to price work?
Those questions are more commercially useful than simply asking whether any tenders are available today.
