€66 to €145
per visit
What moves the price
OCU surveyed independent technicians in fourteen regions in 2023 and found about €66.55 to €145, averaging about €96, for the review that is due every two years. This is the independent route, not a manufacturer or gas supplier plan, and it excludes the separate five-year inspection of the gas installation.
Ask before you book
- Is this a one-off visit or a plan I would have to sign?
- Will I receive the maintenance certificate and sticker?
- Is VAT included?
Fewer published sources exist for this item, so treat the range as a rough guide.

What moves the price, and what to ask
Gas boiler service (the two-yearly review): €66 to €145 per visit
OCU surveyed independent technicians in fourteen regions in 2023 and found about €66.55 to €145, averaging about €96, for the review that is due every two years. This is the independent route, not a manufacturer or gas supplier plan, and it excludes the separate five-year inspection of the gas installation.
- Is this a one-off visit or a plan I would have to sign?
- Will I receive the maintenance certificate and sticker?
- Is VAT included?
Boiler maintenance plan (supplier or manufacturer): €87 to €210 per year
OCU found basic plans from about €87 a year, plans that include replacement parts averaging about €175, and some manufacturer plans near €210. They add call-outs, labour and emergency help, but gas suppliers often exclude the five-year gas inspection, and some limit cover once a boiler passes about 15 years old. A plan is optional.
- Does the plan include parts and labour, or only the visit?
- Is the five-year gas inspection included?
- Does cover change once the boiler is over 15 years old?
Condensing gas boiler, replaced: €1,800 to €3,500 per job, installed
Habitissimo (September 2026) gives about €1,800 for a standard boiler replacement and up to about €3,500 for a condensing model, with labour averaging about €510, a gas supply certificate about €135 and radiators about €200 each if they also need replacing. OCU put a 25 kW condensing boiler at about €2,250 installed in 2023. Flue work and cleaning the circuit can add to it.
- Does the quote include removing the old boiler, the flue and the gas certificate?
- Are the radiators and the circuit cleaning included or extra?
- Which warranty does the boiler carry, and who services it?
Aerotermia (air-to-water heat pump) for heating and hot water: €6,000 to €21,000 per job, installed
One price guide gives roughly €6,000 to €21,000 for heating plus hot water, and the same page says an 80 m² flat starts from about €3,900 and a 100 m² flat from about €8,000, so its own figures are not consistent. Radiators, underfloor heating, a bigger electrical supply and the building's outdoor-unit rules all move the price. Treat it as a starting range and get at least three written quotes.
- Does the quote include the indoor tank, the radiators or underfloor pipes, and the electrical work?
- Has the outdoor unit been checked against the building's community rules?
- What is the seasonal efficiency (SCOP) of the model, and what warranty does it carry?
Air conditioning split unit, installed: €600 to €1,650 1 unit, equipment and installation
National guides quote about €600 to €1,500 for a single split. Barcelona providers quote roughly €1,150 to €1,650 for a mid-to-high range unit fully installed, with labour alone about €300 to €500. Multi-split and ducted systems cost much more.
- Does the price include the unit, VAT and the wall work?
- What is the warranty?

Guides with more detail
How we compiled these ranges
We read published price guides, clinic price lists, comparison sites and official fee schedules, cross-checked each figure against at least two sources wherever they exist, and show the range they agree on. Where only one source exists we say so on the line. The ranges come from 166 sources across the whole price checker, last fully checked 14 October 2026, with additions checked on 22 October 2026. We do not use paid placements, and no listed business influences the numbers. Treat every figure as a starting point for a conversation, never as an offer, and confirm the current price and what is included before you book. Nothing here is medical, legal, tax or financial advice. Spot a price that looks out of date? Email hello@barcelonaenglishpros.com.
