Oil heating on the Côte d'Azur: servicing, repair, and switching to a heat pump
Many older rural houses on the Côte d'Azur still run on oil (fioul domestique). You can no longer fit a new oil boiler, even to replace a dead one. Whether you need the current boiler kept going or want to plan the switch, we connect you with English-speaking contractors who know this terrain.

What you need to know
Who still has oil heating on the Côte d'Azur, and what are their options?
Oil heating (chauffage au fioul) turns up mainly in older rural and semi-rural houses built before mains gas reached them. In the Alpes-Maritimes and Var, that means many mas and bastides (Provençal farmhouses and country houses) and hillside villas from the 1960s to the 1980s. The boiler burns domestic heating oil from a tank on the property.
Since 1 July 2022 you can't install a new oil boiler, and that includes replacing a broken one in an existing house. The law sets a carbon limit for any new heating boiler, and a standard oil boiler is over it. The exceptions are narrow (see the questions below). Repairing and servicing the boiler you have is still legal, and the yearly service is compulsory.
So for most owners the question is when to switch. Riviera winters are mild, which keeps a heat pump efficient for most of the season. On a principal residence, MaPrimeRénov' (the state renovation grant) pays toward an air-to-water or ground-source heat pump and toward removing the oil tank. And once the tank is gone, so is a chore you'd otherwise manage from abroad.
What we can help with
What oil heating work do contractors on the Côte d'Azur carry out?
When the boiler reaches end of life
Switching from oil to a heat pump
When the oil boiler dies, a heat pump is usually the replacement you're allowed to fit. An air-to-water model can often run through the existing radiators, but only a room-by-room heat loss check will confirm it. The tank is decommissioned as part of the project, so make sure the devis (written quote) says so. Our heat pump page covers the process and grants.
Annual boiler service
French law requires a yearly service on every household oil boiler. The technician cleans and adjusts the burner, checks the flue and safety controls, and gives you a certificate. Keep it. Without one, an insurer can refuse a claim after a boiler incident.
Boiler repair
Burner failures, blocked nozzles, pressure problems and pump failures are the usual call-outs, and most are fixed in one visit. On a boiler over 15-20 years old, weigh a big repair bill against switching now. When it finally fails, a new oil boiler is rarely an option.
Oil tank inspection and decommissioning
A leaking tank is an environmental liability, so have it checked for corrosion and leaks from time to time. When you switch, the tank must be drained, cleaned, and either removed or neutralised in place. Buried tanks need a specialist. Either way, it belongs in the scope of any oil-to-heat-pump project.

Get quotesThe case for switching
Why does switching from oil to a heat pump make sense on the Côte d'Azur?
Heating oil follows world oil markets, so the bill can swing sharply from one winter to the next. On a mild Riviera winter day, a heat pump turns each kWh of electricity into 3 to 4 kWh of heat, which makes its heat cheaper than an oil boiler's. Our gas, oil and heat pump running-cost comparison sets the two side by side.
The DPE matters if you plan to sell or let. An oil-heated home typically rates E or F. G-rated homes have been barred from new lets since 2025, and F-rated homes follow in 2028. A heat pump routinely moves a house from E or F to C or D, which removes that risk.
For a second home, there's also the upkeep. An oil tank needs watching, refilling and inspecting, often while nobody is there. A heat pump with a smart thermostat can hold the house at frost-protection temperature all winter, and there's no tank to run dry in January.
What to budget
What pushes up the cost of retiring an oil boiler and its tank?
Start with where the tank sits. One in a cellar or garage is drained, cleaned and taken away or filled in place. A buried tank needs digging out or specialist work where it lies, and a steep plot with no room for a digger adds to that. Ask what paperwork you'll get to show the tank was dealt with.
The radiators come next. A heat pump runs them cooler than an oil boiler, so any radiator that's too small for its room at that temperature has to be replaced. An old mas with thick, uninsulated walls also needs a bigger unit than an insulated house of the same size.
Then there's the outdoor unit. Ask where it can go and how loud it will be at the neighbour's boundary. In a protected village centre, the ABF (the state's heritage architects) may have a say. The house's electricity contract may also need a higher power rating.
Get at least two written quotes built on a room-by-room heat loss calculation, with the tank as its own line. Service and repair on a home over two years old carry 10% TVA (French VAT); a new oil boiler, in the rare case one is allowed, carries 20% and gets no grant.

Questions
Frequently asked questions about oil heating on the Côte d'Azur
If your question isn't here, send it with your request and we'll answer it directly.
Usually not. Since 1 July 2022 a new boiler must meet a carbon limit that standard oil boilers fail, replacements included. The exceptions are narrow: a switch that's technically or legally impossible, or a house where a compliant system would need the electricity grid reinforced. If an installer proposes a new oil boiler, ask which exception applies.
Yes. Nothing forces you to switch, and repairs are allowed. Service and repair of an existing boiler in a home over two years old is billed at 10% TVA. Fitting a new oil or gas boiler, where the law still allows it, has been at 20% since 1 March 2025, with no grant.
On a principal residence, MaPrimeRénov' pays toward an air-to-water or ground-source heat pump and the tank removal. Use an RGE installer and apply before work starts. CEE comes on top, and the Coup de pouce Chauffage (a bigger CEE bonus for replacing a fossil-fuel boiler) makes it far larger when a heat pump replaces an oil boiler. A second home gets only the standard CEE and 5.5% TVA on an air-to-water heat pump.
It has to be decommissioned: drained, cleaned, then removed or filled with an inert material where it stands. You can't simply leave it. Buried tanks need digging out or specialist work in place, so they cost more. A good installer puts the tank on the devis or names who will handle it. Ask before you sign.
Often, but only a room-by-room check will tell you. An air-to-water heat pump runs the radiators cooler than an oil boiler does, so each radiator has to be big enough for its room at that lower temperature. Some will need replacing. Underfloor heating suits a heat pump well. Ask the installer for the heat loss calculation behind their answer.
Yes. French law requires a yearly service on every oil, gas or wood boiler, which covers any household boiler. A qualified technician does it and gives you a certificate. Keep it: after a boiler incident, an insurer can refuse to pay without one. If the house has stood empty, book it before winter.
