Mike Rigby, MD of MRA Research who produce this report, said, “After a difficult start to the year, the Q2 BMBI report has promising signs of growth in the builders’ merchant sector and Repair, Maintenance and Improvement markets. Volumes are rebounding, and while June was no great improvement on May, things are headed in the right direction.

“The latest ONS data suggests improvement, estimating total construction output to have grown +1.2% compared to Q1, with new work (+1.1%) and repair and maintenance (+1.4%) on the up. Again, the month-on-month picture is subdued, with June output growing just +0.3% compared to May. The ONS reports that private housing repair and maintenance, up +3.7%, was the main driver of growth.

“The big question is whether this momentum can be sustained into H2 with growing concerns about possible tax rises in the Chancellor’s Autumn Budget.

“A 0.25% cut in interest rates to 4% in August, the fifth since August last year, has yet to get people spending much more or the economy moving. But August’s GfK consumer confidence index is up two points to -17. Looking back 12 months and looking forward 12 months, the biggest improvements are to personal finances with both scores up by three points. The lift is most likely due to this 7^th cut in interest rates, making the cost of borrowing the lowest for more than two years. Encouragingly, the Major Purchase Index, which is associated with home improvement project spend, also rose two points. And GfK’s savings index, which is not included in the confidence index, dropped four points which suggest people are a little more likely to spend than save compared to July.

“Despite more encouraging news, now would be a very good time for the Chancellor and Prime Minister to make good on their promises to clear the obstacles to build 1.5 million homes by the end of this parliament and get Britain building and the economy growing.”
