What's happened
Britain’s biggest housebuilders are facing a multibillion-pound class-action lawsuit after accusations they colluded on pricing, harming more than 700,000 buyers of new-build homes between 2015 and 2026. The claim seeks up to £4.5bn in compensation, with per-home payments estimated at £3,100-£6,200. The Competition Appeal Tribunal must approve the case before it proceeds.
What's behind the headline?
What this means for home buyers
- The action could unlock compensation for hundreds of thousands of households that bought new builds since 2015.
- It follows a CMA probe into anti-competitive practices in the sector and a subsequent settlement that tightened price information sharing rules.
- The case hinges on whether price-sharing reduced competition; a Tribunal ruling will determine whether the collective action can proceed.
What to watch next
- Tribunal approval is likely within the next 6-12 months, after which individual claims could proceed.
- If successful, payments would come from the firms to affordable housing schemes or direct compensation, depending on the tribunal's framework.
How we got here
The CMA previously investigated the sector and secured a settlement requiring firms not to share pricing information and to fund £100m into affordable housing. The action is led by Mark McLaren for Which? and co-counsel Geradin Partners and Hausfeld, targeting Barratt, Redrow, Taylor Wimpey, Bellway, Berkeley Group, Persimmon, Vistry Group and Bloor Homes.
Our analysis
The Guardian, Sky News, Independent (30 Jun 2026) all report a collective action led by Mark McLaren against Barratt, Redrow, Taylor Wimpey, Bellway, Berkeley Group, Persimmon, Vistry Group and Countryside Partnerships. The CMA investigation and £100m settlement form the backdrop to the case; all three outlets note potential per-home compensation ranging from £3,100 to £6,200 and a total estimate of £2.2-4.5bn.
