Mike Rigby, Managing Director of MRA Research which produces the BMBI report says, “ONS data for April shows +0.9% growth in monthly construction output. At a sector level, the best performers were infrastructure new work, up +2.0%, and private housing repair and maintenance, up +1.5%, which is encouraging.

“After a disappointing start to the year, the Chancellor’s June spending review pitched a confusing blizzard of promises to spend, spend, spend. But the independent Institute for Fiscal Affairs, which the Government indirectly funds to inform us about its public spending, confessed it was ‘baffled’ by a speech that ‘did not appear to be a serious effort to provide any useful information to anybody!’

“However, construction appears to be a major beneficiary. The Chancellor pledged £39bn for social and affordable housing – the biggest investment in a generation – in grants for local authorities, private developers and housing associations. But the gap between spending announcements by the Government and completed buildings is long, and simply jaw-dropping when it comes to infrastructure projects. We wholeheartedly support the Government’s aim of fixing its planning problem to build new homes, but the Government’s 1.5m homes pledge is a hostage to fortune that will surely come back to bite it. Britain is seriously short of the skills to build these new homes and it’s questionable if measures to improve them will work in time. It’s also debatable if it has the building materials capacity to build them despite announcements of several major new industry investments which will also take time to come on stream. Meanwhile, according to the Home Builders Federation, planning bottlenecks seem to be growing not decreasing.”
