How to Quote Plumbing Jobs in the UK 2026
Under-quoting costs you money. Over-quoting costs you jobs. Here is a straightforward guide to quoting plumbing work in the UK in 2026, covering pricing, what to include, and how to send quotes faster without losing accuracy.
What Should a Plumbing Quote Include?
A professional plumbing quote should clearly set out what the customer is getting and what it will cost. Vague quotes lead to scope creep, disputes, and unpaid invoices.
- Your business name, contact details, and VAT number (if VAT registered)
- Customer name and address
- Date the quote was issued and an expiry date (30 days is standard)
- Clear description of the work to be carried out
- Itemised materials list with quantities and prices
- Labour rate and estimated hours, or a fixed labour price
- Any exclusions, what is not included is just as important as what is
- Payment terms, when you expect to be paid and how
- Whether the price is subject to VAT
Quote vs Estimate: Know the Difference
In UK contract law, a quote is a fixed price that is binding if accepted. An estimate is a rough guide that can change. Most plumbers use quotes for defined jobs (fitting a boiler, replacing a bathroom suite) and estimates only for investigative work where the full scope is unknown (finding a leak, diagnosing a system fault).
Practical tip: If you are not sure of the full scope upfront, quote for the diagnostic work separately and give a follow-up quote once you know what you are dealing with. Never estimate a job and then present a significantly higher invoice without having had that conversation first.
How to Price a Plumbing Job
Step 1
Work out your target day rate
Your day rate needs to cover your costs and pay you a proper wage. Work backwards from what you want to earn. A sole trader plumber targeting £50,000 profit per year, working 220 billable days, needs to net roughly £228 per day before materials, so a day rate of £250–£300 is a reasonable starting point in most of the UK (higher in London and South East).
Make sure you have accounted for: NI contributions, insurance, van costs, tool replacement, and the days you won’t be billing (holidays, training, admin, waiting for parts).
Step 2
Estimate materials accurately
Materials are where most plumbing quotes go wrong. Either you under-specify and end up absorbing the difference, or you over-inflate and lose the job.
- Price from your actual supplier with current trade prices, not list prices
- Add a materials markup of 15–25% to cover ordering time, returns, and wastage
- Specify materials clearly in the quote, brand, model, and spec where relevant
- Note that material prices can vary, include a caveat on quotes over 30 days old
Step 3
Assess the job risk
Not all plumbing jobs are equal. A straightforward boiler swap in an accessible location is a different job to the same boiler in a cramped plant room with non-standard connections. Build a buffer into your quote for jobs that carry more risk or complexity.
- Access difficulties, tight spaces, high fixtures, difficult routing
- Unknown existing pipework condition
- Properties with older or non-standard systems
- Jobs that require isolation of shared supplies in blocks of flats
Step 4
Write and send it fast
Speed matters. A customer who gets three plumbers out to quote will often go with whoever comes back first, assuming the prices are in the same ballpark. Sending a professional quote from your phone while still at the property, or within the hour you leave, puts you ahead of most of your competition.
Job management software like Tradify lets you build a quote on site using saved materials and labour rates, and send it as a branded PDF before you have pulled off the driveway.

How to Send Quotes Faster
Most plumbers lose jobs not because they are too expensive, but because they are too slow. Responding to an enquiry the next day, or worse, sending a quote three days after the site visit, gives every competitor a head start.
Job management software like Tradify or Jobber lets you:
- Build quotes on your phone using saved labour rates and materials
- Send professionally branded quotes by email directly from the site visit
- Automatically follow up if a quote has not been accepted within a set number of days
- Convert an accepted quote to a scheduled job and invoice in one tap
Frequently Asked Questions
A professional plumbing quote should include your business name and contact details, VAT number if registered, customer name and address, issue date and expiry date, a clear description of the work to be done, itemised materials with quantities and prices, your labour rate or fixed labour price, any exclusions, and your payment terms.
Spelling out exclusions is as important as listing what is included, it protects you from scope creep and disputes further down the line.
A quote is a fixed price that is legally binding if accepted by the customer. An estimate is a rough guide to cost that can change as the work progresses. Most plumbers use quotes for defined jobs where the scope is clear, and estimates only for investigative or open-ended work where the full extent of the problem is not yet known.
Start with your target day rate, work out what you need to earn to cover all your costs and pay yourself properly. Estimate materials accurately using current trade prices and add a 15–25% markup. Assess the risk and difficulty of the specific job. Then add everything up and check the total against local market rates.
For common jobs, compare against typical ranges: boiler swaps typically run £2,200–£3,500 supply and fit; radiator replacements £300–£600. Your quote should reflect your qualifications, local competition, and site-specific factors.
UK plumber hourly rates in 2026 range from around £40–£65 per hour in the North of England, Scotland, and Wales to £60–£100+ per hour in London and the South East. Gas Safe registered plumbers and those covering commercial or specialist work typically charge at the upper end. Emergency call-out rates are usually 25–50% higher than standard rates.
Same day is the standard to aim for, ideally before you leave the property or within a couple of hours of the visit. The faster your quote arrives, the better your conversion rate. Customers comparing multiple plumbers often go with whoever responds first, assuming prices are in a similar range. Job management apps like Tradify let you build and send quotes from your phone on site.
A materials markup of 15–25% on top of trade prices is standard for UK plumbers. This covers the time spent sourcing and ordering materials, dealing with returns or damaged items, and holding stock. It is a legitimate and widely accepted part of how plumbers price their work, customers understand that trade pricing is different from retail and that organising materials is part of the service.

Both let you build professional quotes on your phone using saved labour rates and materials, send them by email from the site visit, and convert accepted quotes to jobs and invoices in one tap.
