United Kingdom Plumbing Invoice Template

UK plumbers must register for VAT once their taxable turnover exceeds £90,000 and charge 20% on both labor and most parts. Your invoice should include your VAT number (format: GB XXX XXXX XX), a breakdown of the call-out fee, hourly labor rate, and parts at cost plus markup. Gas Safe registration is required for any gas work — it can be worth including your Gas Safe number on invoices involving boiler servicing or gas appliance installation as a trust signal and sector best practice. Plumbing invoices must capture the full cost picture of a job: the call-out or mobilization fee, time on site, parts and materials marked up appropriately, and any emergency or after-hours surcharges. Because materials costs vary widely — a simple washer versus a water heater — itemizing parts separately from labor protects you from disputes and gives clients the transparency they expect. Many plumbers also bill a fixed diagnostic fee before providing a repair quote, which should appear as a distinct line item.

Frequently Asked Questions

Should plumbers charge a call-out fee separately from labor?
Yes. A call-out fee covers travel, vehicle costs, and the time spent mobilizing to the site regardless of how long the job takes. Listing it separately from your hourly labor rate avoids confusion — clients understand they pay a fixed amount to have you arrive, then an hourly rate for the work itself.
How should plumbers invoice for materials and parts?
List parts and materials as a separate line item showing either the actual cost or a marked-up price (a 10–30% markup on trade prices is common and widely accepted). Keep receipts in case a client queries the cost. For large jobs, some plumbers split parts into a separate 'materials invoice' alongside the labor invoice.
What are standard payment terms for plumbing jobs?
Residential plumbing jobs are almost always due on completion — clients pay when the work is done and they're satisfied. For larger commercial projects or water heater installations, a 25–50% deposit upfront to cover materials is standard, with the balance on completion. Net 14 is reasonable for repeat trade customers.
Do plumbers need to charge VAT or GST?
In the UK, plumbers must register for VAT once turnover exceeds £90,000 and charge 20% on labor and most parts. In Australia, you need an ABN and must charge 10% GST once turnover exceeds $75,000 AUD. In the US, taxability of labor and materials varies by state and transaction type — check your specific state's rules.
When do I need to include a VAT number on UK invoices?
You must display your VAT registration number on all invoices if your business is registered for VAT. VAT registration is mandatory once your taxable turnover exceeds £90,000 in a rolling 12-month period. Your VAT number follows the format GB XXX XXXX XX. Invoices without a valid VAT number cannot be used by your customers to reclaim input VAT.
What is the current UK VAT rate for invoices?
The standard UK VAT rate is 20% and applies to most goods and services. A reduced rate of 5% applies to certain items such as home energy and children's car seats. Some supplies — including most food, children's clothing, and books — are zero-rated (0%). Make sure your invoice shows the correct VAT rate for each line item.
What are the legal requirements for a valid UK invoice?
A valid UK VAT invoice must include: a unique sequential invoice number, the date of issue and the supply date, your business name, address, and VAT number, the customer's name and address, a description of the goods or services, the quantity and unit price, the VAT rate and amount for each item, and the total amount including and excluding VAT.
