What does boiler maintenance cost in 2026? A one-off service or a contract
What does boiler maintenance cost? According to the Dutch review platform Werkspot, a one-off service costs €80 to €90 on average, including labour and call-out. With a contract you pay per year: from about €70 for a basic contract to €200 for an all-in contract that also covers breakdowns and parts. Which option is cheapest for you depends on the age of your boiler and how much certainty you want.
In this article you will read what the different kinds of maintenance cost, how often your boiler needs a service, what happens during a service and how Klusbedrijf MSZ charges for maintenance and breakdowns of your boiler in Almere and the surrounding area.
What does a boiler service cost on average?
A boiler service costs €80 to €90 on average in the Netherlands. Labour and call-out are usually included; parts that need replacing can come on top.
Werkspot gives these guide prices (updated 21-08-2026):
| Kind of maintenance | Average cost |
|---|---|
| One-off service | €80 to €90 per service |
| Basic maintenance contract | €70 to €80 per year |
| Service contract | €120 to €150 per year |
| All-in contract | €180 to €200 per year |
These are national averages. The real price depends on the make and model of your boiler, its age and what the engineer finds during the service.
What is in a maintenance, service or all-in contract?
The three kinds of contract differ mainly in what happens when your boiler breaks down between two services. With all three, according to Werkspot, an engineer comes once every two years, and the call-out for that service is included.
- Basic maintenance contract (€70 to €80 per year): only the periodic service. If something is still wrong after the check, you pay for an extra visit or repair yourself.
- Service contract (€120 to €150 per year): maintenance plus help with breakdowns, usually within a day. The cost of parts is partly covered, up to the maximum in your contract.
- All-in contract (€180 to €200 per year): maintenance, breakdown help and all parts as well. Someone is available 24/7.
Read the small print of every contract. Look especially at the maximum for parts, whether the boiler is still covered after a certain age and how quickly someone comes for a breakdown.
One-off service or contract: which is cheaper?
A one-off service is usually cheaper if your boiler is young and rarely breaks down. A contract pays off mainly with an older boiler, where a breakdown is more likely.
A simple sum with Werkspot’s figures shows the difference. If you have your boiler serviced once every two years with a one-off service, you pay €80 to €90 per two years. A basic contract costs €140 to €160 over those two years. For the difference you get convenience and a fixed appointment, but no help with breakdowns. An all-in contract costs €360 to €400 over two years: that only pays for itself if a serious breakdown with parts happens in that time.
Rule of thumb:
- Boiler younger than five years and never a breakdown: a one-off service as the manufacturer advises is usually enough.
- Older boiler or earlier breakdowns: a service contract gives you certainty of quick help.
- No financial surprises wanted: an all-in contract, but compare carefully which parts are covered.
How often does a boiler need maintenance?
For most boilers, a service once every one to two years is enough. A modern boiler that runs little can often manage with once every two years; an older boiler or one in a busy household benefits from a yearly check.
Milieu Centraal, the Dutch public information centre on energy, advises having an older boiler cleaned and checked every year by a CO-certified installer. For modern boilers once every two years is often enough, in consultation with the installer.
According to Werkspot, maintenance is not a legal requirement for home owners, but it is strongly recommended. For rented homes and with some insurers, extra requirements can apply. Renting? Then the landlord usually arranges maintenance; see also our frequently asked questions.
What happens during a service?
During a service the engineer checks whether the boiler works safely and efficiently. According to Werkspot this includes:
- the combustion and the setting of the burner;
- safety, including the flue gas outlet;
- the water pressure of the system;
- cleaning parts and checking for wear.
A clean, well-adjusted boiler uses less gas and is less likely to break down. It also lasts longer, so you can put off replacing it.
What can you do yourself between two services?
You can do a few simple things yourself to prevent breakdowns. They do not replace a service by a professional: checking the combustion and cleaning the inside of the boiler is a job for an engineer.
- Keep an eye on the water pressure. It is usually between 1.5 and 2 bar. If the pressure keeps dropping, read our article boiler pressure keeps dropping.
- Bleed the radiators if they gurgle or do not get warm. See also radiator not heating up.
- Keep the space around the boiler clear of dust and belongings.
What does a breakdown cost without a contract?
Without a contract you pay the call-out and the engineer’s hourly rate for a breakdown, plus any parts. According to Werkspot this can add up quickly, especially for urgent or evening work.
That is also the moment a contract pays for itself. If you have an older boiler and do not want a surprise bill in winter, a service contract is worth considering.
