£5.4bn Southern Construction Framework 6: procurement and lot strategy for project teams
Reviewed by Joe Ashwell

First reported on The Construction Index
30 Second Briefing
Supplier days in Exeter and Winchester next month will brief contractors on the £5.4bn Southern Construction Framework 6, covering public sector projects above £1m across the south west, south east and London. Devon County Council and Hampshire County Council are jointly re-procuring the framework ahead of its 2027 expiry, with SCF 6 to be split into geographic and value-based lots. Civil and building contractors can use the sessions on 2 March (Winchester) and 10 March 2026 (Exeter) to influence delivery models and pipeline access.
Technical Brief
- SCF 6 will only cover public sector projects exceeding £1m contract value.
- Geographic and value-based lotting will segment work across south west, south east and London.
- Early market engagement is being led by Devon County Council and Hampshire County Council as joint clients.
- Current SCF arrangement expires in 2027, so procurement and mobilisation need to bridge that transition.
- Winchester supplier session is scheduled for Monday 2 March; Exeter session for Tuesday 10 March 2026.
Our Take
Within our 736-piece Infrastructure corpus, few frameworks match the geographic span of SCF 6 across the South West, South East and London, which suggests it will be a key route to market for medium and large public clients in southern England through to and beyond the 2027 expiry of the current arrangement.
The £1m minimum project value positions SCF 6 to capture a band of public sector work that is often too small for national mega-frameworks but too large for local term contracts, which typically favours regional contractors with established delivery capacity in Exeter, Winchester and London.
With supplier days set in 2026 ahead of the current framework’s 2027 end date, Devon County Council and Hampshire County Council are signalling an intention to avoid any procurement gap, which should give contractors more certainty for pipeline planning and resource allocation in the south of the UK.
