Every decision we make has a verifiable source behind it.
UK builders merchants collectively turn over £51.6bn, operate from ~6,500 branches and account for 80–85% of the country's construction material supply.
The sector is dominated by major groups (estimated 72% of market) but independent merchants retain a strong competitive position: 23% of tradespeople name their local independent as the supplier that best understands their needs — more than any other channel type. NMBS declared 2024 the Year of the Independent Builders Merchant and its own survey found that 48% of independent members cited personalised customer service as their primary differentiator.
Source: BMF · About BMF (January 2025); AMA Research · UK Builders Merchants Market Report 2024–2028; NMBS / On The Tools survey 2024 · 2025See source→ Repair and maintenance construction output in the UK grew 8.5% in 2024, making it the sole driver of annual growth; it accounts for over 44% of all UK construction output.
Non-housing repair and maintenance and private housing repair and maintenance were the two largest positive contributors. This structural shift towards RMI work — retrofits, energy efficiency upgrades, re-roofing, bathroom and kitchen renovations — feeds directly into generalist builders merchants and specialist plumbing, heating and electrical merchants.

The research — a Knowledge Transfer Partnership between Oxford Brookes Business School and ProspectSoft — reviewed 15.8 million sales across two million B2B customer relationships. For builders merchants, the finding translates directly: without a trade-account CRM tracking order recency, frequency and value, a significant share of the active ledger quietly migrates to competitors.

For builders merchants, this confirms that the trade counter and branch phone remain the primary revenue channel — and that the speed, accuracy and quality of response at those touchpoints (phone, WhatsApp, counter) is the primary competitive differentiator. Digital channels are supplementary, not a replacement.

For a builders merchant managing hundreds of trade accounts across multiple product categories, a CRM system that tracks order recency, dormant accounts and quote follow-up is the operational infrastructure that prevents silent revenue loss.

For B2B wholesalers and builders merchants, reorder reminders and stock-availability notifications sent via WhatsApp significantly outperform email. The tradesperson already uses WhatsApp on site; the merchant who meets them on that channel removes friction from the ordering process entirely.

For a builders merchant competing for new trade accounts, Google reviews act as a proxy for service reliability. A branch with 4.6 stars and 80 reviews referencing stock availability, knowledgeable staff and fast turnaround communicates exactly what a tradesperson evaluating a new supplier is looking for.
Source: BrightLocal · Local Consumer Review Survey 2024 · 2024See source→ BMBI merchant value sales were -4.1% year-on-year in 2024, but H1 2025 recovered to +1.9% value growth driven by +4.0% volume.
The recovery in volume signals renewed trade activity even as price deflation squeezed headline value. Merchants with stronger account visibility and faster response capability have been better placed to capture the volume upswing — particularly in plumbing, heating and RMI-led categories.
