Plumbing service playbook.
A UK independent plumbing + heating firm running domestic + small-commercial work — boiler installs + servicing, bathroom installs, emergency call-outs and gas-safe work. The 2026 win is balancing high-margin boiler installs (heat-pump-ready) with a recurring service plan book and a 24/7 emergency line.
Reference fit-out · Plumbing service
Overview
A UK indie plumbing + heating firm in 2026 runs four engines: boiler installs (£2,400–£4,400 combi, £4,400–£8,400 system + heat-pump £8,400–£18,000 minus BUS grant, 28–42% gross margin after parts + labour, 4–8/week per engineer with mate), service + repair (£148–£420 ticket, 56–68% margin, 12–18/week, plus annual service plans), bathroom installs (£3,400–£18,000, 22–32% margin after subbie trades, 1–2 month-long jobs per crew), and emergency call-outs (£180–£480, 64–74% margin, premium evening/weekend tariff). Maths for 3-engineer crew: 18 installs × £3,400 = £61k + 60 services × £180 = £11k + 2 bathrooms × £9k = £18k + £8k emergency = ~£98k/month gross. Net 18–24%. The 2026 strategy is heat-pump certification + BUS grant fluency — government-backed £7,500 grants are driving 38–48% YoY growth in heat-pump installs, and certified MCS installers are scarce.
