Vistry said: “Whilst the group is not aware of liability in any of these cases, we are committed to proper consideration of any relevant case and to meeting any liability which we identify, and, in addition, to offering appropriate support in circumstances where building owners do not meet their obligations.
“We anticipate that this will give rise to financial liabilities, which we have estimated to be between £10m and £25m.
“We have brought forward provisions in the balance sheet of £9.9m, and have now increased this to £20.9m, by way of an exceptional charge to the Profit and Loss account of £11m.”

“Assuming stable market conditions we expect to deliver a step-up in housebuilding completions in 2021 to c. 6,300 units and an improvement in adjusted gross margin to c. 22%.
