How Much to Charge for a Boiler Service (UK 2026)
There is no single national price for a boiler service — it varies by region, travel and the job in front of you. The reliable answer is to work your price out from your own costs, then sense-check it against local rates.
A boiler service is bread-and-butter work, but pricing it well is where a lot of engineers leak margin. Charge too little and a full diary still leaves you short; pin your price to a competitor's advert and you inherit their costs, not yours.
This guide gives indicative 2026 UK ranges to orient you, then shows how to build your own price from your day rate, your time on site and your costs. Every figure here is a regional indication, not a fixed national price — your number should come from your business.
Key takeaways
- A typical domestic boiler service commonly falls in roughly the £70–£120 range, with London and higher-cost areas often more — treat this as indicative, not fixed.
- Region, travel and time on site move the price as much as the work itself.
- Price from your day rate and costs, not by copying a competitor's advertised figure.
- A landlord service with a gas safety record (CP12) is more work than a standalone service and should price higher.
- Service plans and contracts trade a lower per-visit price for predictable, recurring work — price them deliberately.
What a proper service includes
A service is not just a visual glance. Done properly it covers checking the boiler operates correctly, inspecting the flue and combustion (typically a flue gas analysis), checking the working gas pressure and rating, inspecting seals and key components, checking safety devices and ventilation, and leaving the appliance clean and safe with the work recorded.
That scope is what justifies the price. When a customer compares your figure with a cheaper one, the difference is often what is actually being done — so be clear about the checks included, because a thorough service protects the warranty and the customer far better than a quick once-over.
What drives the price
Region is the biggest single factor — labour rates in London and the South East sit above much of the rest of the UK, and a figure that is healthy in one area is loss-making in another. Travel matters too: a service the far side of your patch costs you unpaid driving time either side of the appointment.
Then there is the job itself. A straightforward service on a well-maintained boiler is quick; a neglected or first-time service takes longer and may surface faults. A landlord instruction that includes a gas safety record (CP12) is more work and more paperwork than a one-off homeowner service, and should be priced accordingly.
| Job type | Indicative price (varies by region) |
|---|---|
| Standard domestic service | £70–£120 |
| Service + landlord gas safety (CP12) | £100–£160 |
| First-time service / neglected boiler | £110–£180+ |
How to price from your day rate and costs
Start from the day rate you actually need — one that covers your wage, van, tools, insurance, registration, training and downtime, not just an hourly figure plucked from the air. Divide that into a realistic chargeable time for the visit, including the driving and the paperwork, and you have the labour cost of a service.
Add any materials and a sensible margin, and you have a price you can defend without reference to anyone else's advert. Do this once with a day rate calculator and you can price every service consistently, then adjust for travel and the state of the appliance in front of you.
Your price, not the market's
The market rate tells you whether you are roughly in the right area; your costs tell you what you must charge to make money. When the two disagree, trust your costs and fix the business, not the price alone.
Pricing service contracts and plans
Many engineers offer an annual service plan or a landlord contract covering multiple properties. These trade a lower price per visit for guaranteed, repeat work and a smoother diary — worth it, but only if the discount is deliberate and still leaves margin after the extra admin of managing the plan.
Price a plan from the same cost base as a one-off, then decide what recurring commitment is worth to you. Bill it cleanly and keep the records against each property, so renewals, reminders and the annual gas safety dates all sit in one place rather than in your head.
Keep plans and paperwork together
Holding the service dates, certificates and invoices for each customer in TradePlanr means reminders and renewals look after themselves — recurring service work is far easier to run when the records are in one place.
Frequently asked questions
How much should I charge for a boiler service in 2026?
A typical domestic service commonly falls in roughly the £70–£120 range, with London and higher-cost areas often above that. Treat this as an indicative, regional guide — work your actual price out from your day rate, travel and costs rather than a national figure.
Should I match a cheaper competitor's price?
Not blindly. A cheaper advert may reflect a lighter service, lower costs or a loss-leader, none of which are your business. Use local prices as a sense-check, but set your figure from your own costs and margin so a full diary is actually profitable.
Why does a landlord service cost more than a homeowner one?
Because it usually includes a landlord gas safety record (CP12) on top of the service — more checks, more documentation and often multiple appliances or properties. That extra work and paperwork should be reflected in a higher price.
How should I price a service plan or contract?
Start from the same cost base as a one-off service, then decide what a lower per-visit price is worth in exchange for guaranteed, recurring work. Make sure the discount still leaves margin after the admin of running the plan, and keep clean records for each property.
