Business finance for plumbers & heating engineers

Why plumbing and heating cash flow is lumpy

Plumbing and heating firms juggle two cash-flow patterns at once. Reactive work — breakdowns, leaks and emergency call-outs — spikes hard in winter when boilers fail in the cold. Planned work — bathrooms, full system installs, commercial heating and renewables — runs on quotes, deposits and staged payments. Managing both from one bank balance is the everyday challenge.

The squeeze comes from buying ahead. A boiler swap means paying a merchant for the boiler, flue, controls and sundries up front, while the customer may settle on completion — or, on commercial and new-build work, weeks later on contract terms. Merchant accounts have credit limits that a busy month can blow straight through, and a single large install can soak up more cash than the whole month's takings. Add a winter rush of parts you must hold to respond fast, and capital is tied up everywhere.

Common uses of funding

For plumbing and heating businesses, working capital usually covers:

• Boilers and major parts up front — funding installs before the customer or contractor pays.
• Merchant account headroom — covering spend that exceeds your trade credit limit in a busy spell.
• Winter demand spikes — extra stock, overtime and possibly temporary labour for the breakdown season.
• Bridging staged and commercial jobs — carrying larger installs paid in stages or on delayed terms.
• Vans, tools and test gear — keeping engineers equipped and on the road.
• Gas Safe and skills — registration, F-gas, unvented and renewables training to widen the work you can take.

What to think about before borrowing

Tie the borrowing to a clear repayment source. Funding a boiler against a job that completes and pays in days is low-risk; using short-term money to prop up a thin month repeatedly is a warning sign worth addressing at root. Be especially careful with deposits — money a customer has paid towards a job isn't yet your profit, so don't treat it as spare cash.

Compare the total cost of a facility against the margin on the work it funds, and check repayments fall when jobs actually pay, not in your leanest week. For kit you'll own for years — a van, say — asset finance is usually cheaper than working capital. The aim is simple: borrow to do more profitable work sooner, not to delay a problem.

How short-term company finance fits

Credicorp lends to the limited company, not to the director — so there's no personal guarantee and your personal assets aren't pledged against a business facility. As an exempt business lender we provide short-term working capital to UK limited companies, structured around how a trade business actually buys, fits and gets paid.

That means money that lands when the merchant invoice is due and clears when the job pays. A business loan suits a single defined push — a large commercial install or a batch of boilers. A revolving facility like Credicorp Flex fits the steady rhythm of installs and call-outs, letting you draw to buy parts and repay as each job settles, then draw again. You can apply online. If you also handle wiring, our electricians page covers the same ground from that angle.
