Free Invoice Template for Plumbers

A clear plumbing invoice helps customers understand what they paid for and protects you if a dispute arises. Include:

• Date and time of work
• Property address where work was carried out
• Description of work — e.g., "Replace kitchen tap — supply and fit", "Clear blocked drain — CCTV inspection + jetting"
• Labour hours and rate — break down if the job had multiple stages
• Materials and parts — list each item, quantity, and unit cost
• Call-out fee if applicable
• VAT if you are VAT-registered
• Guarantee or warranty period for the work (in the notes field)

Most plumbing invoices split into two main components:

Labour: Charge an hourly rate or a fixed job price. Hourly rates for qualified plumbers in the UK typically range from £50–£120/hour depending on region and job type. Emergency callouts command a significant premium — 1.5–2× the standard rate for evenings and weekends is common.

Materials: Parts purchased specifically for the job are passed through to the customer. You can add a small markup (10–20%) for sourcing, storage, and warranty responsibility, or charge at trade price. List each part individually with quantity and unit price — customers are less likely to query a clearly itemised materials list than a lump-sum "materials" charge.

Establishing a clear call-out fee policy reduces disputes and compensates you fairly for travel time:

• Standard call-out fee: A fixed charge to attend the job, regardless of duration. Typically £50–£100. Applied even if the job is quick or no fault is found.
• Emergency/out-of-hours rate: A higher rate (or surcharge) for evenings, weekends, and bank holidays. Be transparent about when these rates apply.
• Minimum charge: A minimum charge for short jobs (e.g., a minimum of 1 hour labour) prevents short visits being undercharged relative to your travel time.

State your call-out and emergency rates in your quote or initial communication, and reference them on the invoice when applied.

Plumbing services are standard-rated for VAT purposes in most countries:

• UK plumbers: Register for VAT when turnover exceeds £90,000. The standard rate (20%) applies to labour and materials. New residential builds may qualify for a reduced VAT rate (5%) — check HMRC guidance for qualifying works.
• EU plumbers: Standard VAT rates apply — 19% (DE), 20% (FR), 21% (ES/NL), 22% (IT). Renovation and repair work on private dwellings may qualify for a reduced rate in some EU member states.
• CIS scheme (UK): If working as a subcontractor in the UK, your contractor may deduct 20% under the Construction Industry Scheme (CIS). Include your UTR number on invoices to subcontractors.
