Plumbers accounting, handled.

Not for the homeowner work itself — CIS only applies when one business hires another for construction. But if you take on a subbie, even occasionally, on those jobs, you become a contractor under CIS and must register, verify them, and submit monthly returns. Many small plumbers trip into CIS the first time they pay a labourer cash — we set you up properly before that happens.

Call-out fees and out-of-hours premiums are standard-rated VAT just like the rest of your labour — the time of day doesn't change the treatment. For tax, they're simply additional turnover. The bookkeeping risk is unrecorded cash jobs from late-night call-outs, which HMRC's enquiry teams know to look for. We use mobile invoicing apps that capture the income at the kitchen sink, not the kitchen table at midnight.

From April 2022 to March 2027, the installation of qualifying energy-saving materials in residential property is zero-rated VAT in Great Britain (including air-source heat pumps, solar panels, and insulation). Standard gas boiler replacements are still 20%, unless installed alongside qualifying ESMs as part of a single supply. We help you categorise jobs correctly so you charge the right rate and reclaim the right input VAT.

Sole trader plumbers can use either method but must stick with the choice for as long as that vehicle is in use. For a high-mileage van that cost £25,000 with significant fuel and maintenance, actual costs plus capital allowances almost always beats the 45p/25p flat rate. We compare both for your real numbers in year one and lock you onto the more efficient method.

At that level, our Essentials at £99/month covers Self-Assessment, bookkeeping, and VAT (you'll be near the £90k threshold). Most plumbers move to Premium Plus at £199 once they take on a subbie or van and need CIS plus payroll.
