Emile van der Ryst, Senior Client Insight Manager – Trade at GfK Retail & Technology UK comments: “The plumbing & heating industry has continued its strong performance into Q3, but there’s evidence of the market starting to slow down. Supply chain issues were managed well and should now start easing off a bit more. I expect the end of the stamp duty holiday will slow down growth, whilst the recent acquisitions will make for some interesting reading in the coming months.”

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.

Based on data from GfK’s Plumbing & Heating Merchant Panel, which represents over 80% of the market by value, the report provides reliable data and a platform and voice for the industry, as well as for leading plumbing & heating brands. It is produced by MRA Research for the Builders Merchants Federation. There is no overlap or double counting between PHMI and the Builders Merchants Building Index (BMBI) sales data.
