Plumbing Pricing Guide UK — Plumber Hourly Rates and Job Costs (2026)

UK Plumber Hourly Rates and Day Rates 2026

Plumber hourly rates in the UK vary significantly by region. Outside London, most sole trader plumbers charge between £45 and £80 per hour for standard domestic work in 2026. In London and the South East, the range runs from £70 to £120 per hour, reflecting higher overheads, congestion charges, and stronger demand. Day rates follow the same regional pattern: £200 to £300 per day in most of England and Wales, rising to £300 to £400 in London.

Emergency and out-of-hours callouts command a significant uplift. Evenings, weekends, and bank holidays typically attract a 1.5x to 2x premium on the standard hourly rate. A plumber charging £60 per hour during the week can legitimately charge £90 to £120 per hour on a Sunday evening — and customers with a burst pipe rarely push back once they understand the rate upfront.

• Standard hourly rate (outside London): £45–£80/hr
• London and South East hourly rate: £70–£120/hr
• Day rate (UK outside London): £200–£300/day
• Day rate (London): £300–£400/day
• Out-of-hours / emergency uplift: 1.5–2x standard rate

Common Plumbing Job Prices

Fixed-price domestic plumbing jobs are the bread and butter of most small plumbing businesses. The ranges below reflect typical 2026 prices for labour and any minor parts included, assuming good access and standard residential pipework. Complex access, older properties, or concealed pipework will push prices higher.

• Annual boiler service: £70–£120
• Boiler repair (common faults, parts variable): £150–£400+
• Radiator bleed and refill: £50–£80
• Radiator replacement (drain, swap, refill): £150–£300
• Powerflush (up to 10 radiators): £300–£450; larger systems £450–£600+
• Leak repair (trace and fix, accessible pipework): £100–£300
• Stopcock replacement: £85–£140
• Toilet repair (cistern internals): £70–£110

For boiler repairs, the labour figure is only part of the cost — parts for common faults like a faulty pump, PCB, or diverter valve can add £80 to £300 on top. Always price parts separately with your markup applied, and present a total figure to the customer before ordering.

Bathroom and En-Suite Fit Costs

Bathroom fitting is among the highest-value domestic plumbing work available and also the most variable to price. The figures below are for labour only — materials (sanitaryware, taps, shower valves, waste fittings) are highly variable and priced separately.

• Full bathroom strip and re-fit (labour only): £800–£1,500
• En-suite fit (labour only): £500–£900
• Cloakroom / WC fit (labour only): £300–£600

These ranges assume existing pipework in usable positions and straightforward first-fix connections. If the job involves moving soil stacks, extending hot or cold runs across the property, or working in a difficult access space, add accordingly. A watertight quote should specify exactly what the labour covers and exclude any work discovered once walls are opened.

When you supply materials as well as fit them, apply a 25 to 40 per cent markup on trade cost. This is standard practice, covers your procurement time and warranty risk, and represents significant additional margin on a full bathroom suite.

Hot and Cold Water Jobs

Smaller cold and hot water jobs are often the most efficient work a plumber can take on — high hourly yield, short visit, straightforward scope. The key is pricing them firmly and not undervaluing the expertise required to get them right first time.

• Fitting an outside tap (including back-plate elbow and pipework): £100–£200
• Replacing kitchen or bathroom taps (per set, existing connections): £80–£150
• Replacing a toilet (supply and fit close-coupled): £150–£300
• Unblocking a drain (rodding / plunging): £80–£200
• Fitting a washing machine or dishwasher (connections only): £60–£100

Underfloor Heating Installation Pricing

Wet underfloor heating (UFH) is increasingly requested in new bathrooms, extensions, and renovation projects — and it commands a meaningful premium over standard radiator work. Pricing a UFH installation requires breaking down the components clearly.

• UFH pipe and screed installation labour: £15–£30 per m² (varies with room complexity)
• Manifold supply and fit: £200–£500 depending on zones
• Zone valve and actuator head per zone: £40–£80 labour
• System commissioning and flow balancing: £100–£200

A typical single-room wet UFH installation in an extension or kitchen (20–30 m², one zone, connected to existing boiler) realistically runs to £900–£1,800 in labour, plus materials. Multi-room or whole-house systems scale significantly. Always commission the system yourself rather than leaving it to the screeder or builder — faults discovered after screed is poured are expensive to resolve.

UFH work pairs well with boiler upgrades and heat pump installations. A customer fitting UFH throughout a renovation is a strong candidate for a boiler replacement or heat pump at the same time — higher average job value, same mobilisation cost.

Cylinder and Hot Water System Work

Cylinder work is some of the most regulated and highest-value plumbing available to a qualified engineer. Unvented hot water cylinders — Megaflow, Gledhill, OSO, and equivalents — require a G3-qualified installer under Part G of the Building Regulations. Only G3 holders can legally install or commission an unvented system and self-certify the work. If you hold this qualification, price accordingly.

• Unvented cylinder installation (labour only, G3 required): £800–£1,200
• Vented cylinder replacement (labour only): £300–£600
• Megaflow / unvented annual service: £100–£160
• Expansion vessel replacement: £150–£250
• Pressure relief valve replacement: £100–£180

Cylinder pricing is frequently under-quoted because plumbers price it like a standard boiler job. An unvented installation involves a Building Regulations notification, a G3 compliance certificate, correct tundish and discharge pipework positioning, and liability for a pressurised system. Price it to reflect the qualification, the paperwork, and the risk.

Materials Markup for Plumbing

Marking up materials is standard practice across all trades and is not price-gouging — it covers your merchant account administration, the time spent sourcing and collecting parts, delivery management, and the risk that a faulty component needs replacing on your time. A markup of 20 to 40 per cent on trade cost is widely accepted in domestic plumbing.

• Minor parts (valves, fittings, washers): 25–40% on trade cost
• Major components (cylinder, boiler, shower valve): 20–30% on trade cost
• Sanitaryware and bathroom suite items: 25–35% on trade cost

If a customer insists on supplying their own materials, adjust your labour rate upward to compensate for the lost margin — and make clear in your quote that you accept no liability for customer-supplied parts that are incorrect, faulty, or incompatible. Many plumbers add a “customer-supplied materials” surcharge of 10 to 15 per cent on labour to reflect the additional risk and admin involved.

Opening a trade account with your main merchant (Wolseley, Screwfix Trade, City Plumbing) gives you better pricing, a credit facility, and the ability to collect parts quickly. The margin between your trade price and your quoted customer price is real profit — protect it.

Fixed Price vs Day Rate — When Each Works

The choice between fixed price and day rate depends almost entirely on how predictable the job scope is. Get this wrong and you either lose money on a fixed price that ballooned, or lose the job to a competitor who quoted fixed when you quoted day rate.

• Fixed price works best for: boiler service, tap replacement, radiator bleed, toilet repair, outside tap — jobs with clear scope and no hidden variables.
• Day rate works best for: bathroom first fix, replumbing behind walls, investigations and trace-and-fix work, any job where opening up reveals the unknown.

When quoting fixed price, be specific about what is and is not included. A well-written fixed-price quote states the work to be done, the materials included, any assumptions (e.g. “assumes accessible pipework in good condition”), and a clear exclusion for anything discovered that falls outside that scope.

For day rate jobs, provide a written estimate of the likely number of days required. A customer given a range of “two to three days depending on what we find” is far better prepared than one given a fixed price that later needs renegotiating. Include a daywork clause in any fixed-price contract for jobs where unknowns are plausible — this protects you without alarming the customer.

Emergency Callout Pricing

Emergency plumbing is where customers have the lowest price sensitivity and the highest urgency. Priced and communicated correctly, out-of-hours work is some of the most profitable a plumber can do. Priced badly — or with no upfront communication — it is the source of the most disputes and bad reviews.

• Standard emergency callout fee (attending, first 30 min): £60–£120
• Out-of-hours hourly rate (evenings, weekends): 1.5–2x standard rate
• Minimum charge for any emergency visit: typically 1–1.5 hours at out-of-hours rate

State your emergency rates publicly — on your website, your Google Business Profile, and when a customer calls. Confirm the callout fee and out-of-hours rate verbally before you attend, and follow up with a written message (WhatsApp or SMS) so the customer has it in writing. Customers who agree to the rate before you arrive almost never dispute the invoice on completion.

Building a Profitable Plumbing Business

Reactive plumbing — responding to breakdowns and one-off jobs — is the foundation of most domestic plumbing businesses, but it is lumpy income. The plumbers who build genuinely profitable businesses do two things: they develop a mix of reactive and planned work, and they price for their postcode rather than for the national average.

Planned work means annual boiler service contracts, cylinder servicing agreements, and landlord maintenance retainers. A boiler care plan at £12 to £20 per month per customer generates predictable monthly revenue regardless of what the reactive diary looks like. At 60 contract customers, that is £720 to £1,200 per month before a single callout is attended. Building that base takes 18 to 24 months of consistent follow-up with existing customers — but the compounding effect is significant.

• Basic service-only annual contract: £9–£14/month per customer
• Full service plus labour-only breakdown cover: £16–£25/month
• Landlord maintenance retainer (portfolio pricing): negotiated per property

Pricing for your postcode means researching what the market in your specific area actually charges — not what a plumber in a different city charges. Use your enquiry data to identify which job types convert most reliably and at the best margin. Jobs that are easy to win but take all day at a low fixed price are less profitable than higher-ticket work that converts less often but pays more per day. Tracking which enquiries convert and at what price is the only way to understand your actual profitable job mix — and to shift your marketing and quoting toward more of it.
