Mike Rigby, CEO of MRA Research, which produces the report comments: “Quarter three figures show that sales through specialist plumbing and heating merchants are gathering momentum after a weak start to the year.

“Strong summer sales from pent-up demand accumulating during the winter lockdown and the usual annual uplift from ‘heating season’ sales has boosted growth for the industry. We expect this to continue into Q4, driven by homeowners looking to improve the energy efficiency of their heating and hot water systems to counteract the steep rise in energy costs.”

The Plumbing & Heating Merchant Index (PHMI) is the first to analyse point of sales data collated from specialist plumbing & heating merchants with combined annual sales of £3bn, to chart their performance month-to-month.

The PHMI data is from GfK’s Plumbing & Heating Merchant Panel, which represents over 80% of Britain’s specialist plumbing & heating merchants’ sales. The PHMI is a brand of the Builders Merchants Federation, and reports are produced by MRA Research. There is no overlap or double counting between PHMI and Builders Merchants Building Index (BMBI) sales data.
