New boiler cost: what is the average installed price?

The average cost of a new boiler installation is €1,600 to €2,600 excluding VAT. This covers a supplied and installed HR combi boiler.

This band covers a standard job on the same spot. It includes the boiler, normal fitting parts, tests and start-up. A move, new flue or building work is extra.

These price bands come from Skilled Contractors Pricing Model v1.0.0. If you buy a new boiler yourself, the boiler installation cost for labour only is €350 to €900 excluding VAT. The appliance-only reference is €900 to €2,100. Ask first whether the installer accepts a customer-supplied model.

With 21% VAT, €1,600 to €2,600 becomes €1,936 to €3,146. Whether VAT is added depends on the contractor. The Dutch Tax Administration explains the KOR. A contractor using it does not charge VAT. Compare every quote on the same tax basis.

This page owns the cost to replace a central-heating boiler. Boiler cover, periodic service and maintenance contracts stay with the maintenance guide.

What are the different boiler types and their associated costs?

Boiler costs depend on the type of boiler, output and hot-water class. The installer should size the system for the home. They should check its size and heat loss.

A combi boiler supplies central heating and domestic hot water from one unit.
A solo boiler works with a separate hot-water cylinder. It is sometimes called a system boiler in English.
A conventional boiler is a UK search term. Dutch quotes usually use HR combi or solo boiler.
There is no single best new boiler. The right boiler matches the home, radiators and simultaneous hot-water demand.

A quote may name an Intergas or Nefit Bosch model. Compare capacity, controls and warranty, not just the brand or upfront cost.

What factors influence the cost of a boiler replacement?

Boiler installation costs rise with extra work. Replacing the boiler may require a flue, pipework, controls or a move. Each change adds an additional cost. Ask the provider to price each item. These are the main boiler replacement costs to consider.

A replacement flue and air-supply route if the existing system is unsuitable.
Gas, water or condensate pipe changes.
A new expansion vessel, thermostat or thermostatic radiator valves.
Moving the unit or changing the mounting surface.
Removing the old boiler, call-out charges and non-standard materials.

New radiators are not automatically part of a replacement boiler. They become a separate upgrade only when their condition, output or controls require it.

When should you replace your boiler?

Replace an old boiler when faults repeat, key parts are unavailable or a major repair is poor value. Age alone is not enough.

Repeated faults or unstable heating and hot water.
Falling boiler efficiency or unexplained higher gas consumption.
Leaks, corrosion or recurring boiler pressure problems.
A high repair estimate for an older unit.

Ask for both repair and replacement costs in advance. Compare the likely life after repair, the warranty and the risk of another fault.

Is it worth replacing a 15-year-old boiler?

A 15-year-old boiler deserves a close check, but age alone does not decide the job. Replacement may make sense when faults repeat, parts are scarce or repair costs are high.

Should I repair or replace my boiler?

Repair can make sense for a sound unit with an affordable fault. Replace it when repair offers poor value or reliability is low. Ask a CO-certified company to inspect the actual system.

Gas boiler or heat pump?

A new gas boiler has a lower initial price than most heat-pump projects and often fits the existing system. A hybrid heat pump can reduce gas use for space heating, but it adds equipment and installation work.

The €1,600 to €2,600 band does not include a heat pump. It also makes no claim about future fuel prices or guaranteed costs and savings. Check the current local heat plan, regulations and RVO subsidy conditions before choosing a new heating route.

Who may replace a boiler in the Netherlands?

The Dutch government business portal states that only a CO-certified company may install, repair, service or commission a gas-burning system. The rule also covers the air supply and flue. Check the public register before appointing boiler installers.

Gas Safe engineers is a UK label, not the Dutch proof. An English-speaking homeowner should ask for Dutch CO certification.

RVO states that heating systems with a nominal output of 70 kW or more require a technical inspection. A single domestic cv-ketel is usually below that threshold. The owner of a larger or linked boiler system should have the total nominal output checked.

Is replacing a boiler a big job, and how long does it take?

Getting a new boiler installed on the same location often fits within one working day. Installation takes longer when the flue changes, pipework moves or the system needs preparation.

The engineer isolates gas, water and power.
The old boiler is disconnected.
The replacement boiler and controls are installed.
The system is filled, vented, tested and commissioned.
The user receives operating and pressure guidance.

How can you save money on a boiler replacement?

Compare each boiler quote on the same scope. Do not pick the lowest headline price alone. Read each line. Compare the total price. Boiler prices depend on type, output, controls and extra work.

Get two or three quotes. Use the same boiler specification for each.
List the appliance and labour separately. Do the same for the flue, thermostat, vessel and disposal.
Check the VAT basis. Ask if KOR applies.
Confirm the product warranty. Confirm the workmanship warranty.
Check the company's CO certificate.

Are grants or financial assistance available for boiler replacement?

The cited RVO scheme does not grant support for a gas boiler alone. It may support a qualifying heat pump. Check the current RVO conditions before ordering a combined project.

Frequently asked questions

Answers to common questions.

What is the boiler replacement cost including installation?

A standard HR combi replacement costs €1,600 to €2,600 excluding VAT on the same location. At 21% VAT, the consumer total is €1,936 to €3,146. Site-specific extras are separate.

What does installation alone cost?

Labour to replace a boiler you bought yourself is €350 to €900 excluding VAT. Check that the installer accepts the model and state exactly which fitting materials are included.

Can I still get a new gas boiler in 2026?

This cost guide does not treat a standard replacement as prohibited. Check current national rules, the local heat plan and whether a hybrid or electric option suits the property before ordering.

Should I repair or replace a 15-year-old boiler?

Age is only one factor. Compare the repair price, parts supply, reliability after repair, replacement cost and warranty. A CO-certified company should assess the actual system.

How long does boiler replacement take?

A standard same-location replacement often fits within one working day. A new flue, moved pipes or other site work can extend the job.

Is a heat-pump subsidy available for the gas boiler?

RVO's heat-pump subsidy concerns the qualifying heat pump, not a gas boiler on its own. Check the current scheme conditions before you commit to a combined project.

Must the flue be replaced?

The CO-certified installer must decide whether the existing air supply and flue are safe and compatible with the new appliance. Put replacement or approved reuse in writing.

Who can install a replacement boiler?

Use a Dutch CO-certified company. The certification covers work on the gas appliance, its air supply and flue.
