Mike Rigby, Managing Director of MRA Research which produces the BMBI report says: “As I write this it’s Day 47 of the Iran War and it’s hard to see an end. Bewilderingly, Trump’s answer to Iran’s refusal to capitulate is to blockade their blockade so the Straits of Hormuz are totally sealed off to everyone. The rest of the world is being held over a barrel (an oil one). About one month from now, when average stocks run out, the global economy will be facing the consequences of an actual gas and oil shortage of about 10 million barrels a day, according to Wood Mackenzie, the global leader in data, analytics and insights for the energy and natural resources industry.

That’s equivalent to an economic hit like Covid. Some countries are already suffering shortages and knock on effects.

“The latest GfK Consumer Confidence Index shows a 2-point fall in March, to -21 – the third month of decline since January. The biggest drop was in views of the general economic situation over the next 12 months, which fell 6 points to -37. The major purchase index, indicative of potential spending on home improvements, tumbled 4 points to -18, while the savings index increased 6 points to 27. Consumers are very concerned about the impact of the war on the economy and are favouring money in the bank over spending.

“But there are some green shoots for merchants with a surge in consumer interest in electric vehicles and home energy upgrades, as consumers try to uncouple from erratic oil and gas prices. Octopus Energy and British Gas have both seen record increases in solar and heat pump enquiries. Paul Haynes, BAXI’s Product, Solutions & Marketing Director, BMBI’s Expert for Heating & Hot Water Solutions, says the heat pumps market was up +25% in 2025 year on year.”

Set up and run by MRA Research, the BMBI – a brand of the Builders Merchants Federation – is a monthly index of builders’ merchant sales, and the most reliable, up-to-date measure of Repair, Maintenance, and Improvement (RMI) activity in the UK. The index is based on actual sales from NiQ GfK’s Builders’ Merchant Point of Sale Tracking Data, which captures value sales out to builders from generalist builders’ merchants, accounting for 88% of total sales from builders’ merchants throughout Great Britain. An in-depth review, which includes commentary by sector experts, is provided each quarter.
