Nick Raynsford, the former construction minister, has launched a last-ditch attempt to ensure that changes to the Construction Act are considered by MPs in the current session of parliament.

It was hoped that changes to payment and adjudication procedures would be made in a dedicated Construction Bill, but this was not included in the legislative programme announced in the Queen’s speech this month.

It is understood that Raynsford hopes the changes will be added as an amendment to the Housing and Regeneration Bill. This received its second reading in the House of Commons on Tuesday.

A source familiar with the situation said: “He is offering to act as a go-between for officials in different departments to try to get these elements into the bill.”
