Yes, you can get a full renovation team near Carcassonne that speaks English and handles the French paperwork for you. Raynier Entreprise has worked in the Aude since 1987, with 20 in-house tradespeople covering plumbing, hot water, heating, heat pumps, air conditioning, roofing and zinc work, and solar. No subcontractors, one point of contact, and every job covered by the French 10-year "décennale" insurance.
Key takeaway: renovating a French property as a British or English-speaking buyer does not mean you need to master French building jargon or chase three different subcontractors. Raynier is a single, RGE-certified, décennale-insured company covering plumbing, heating, air conditioning, roofing/zinc and solar around Carcassonne. We explain every quote in plain English before you sign anything, and we handle the French administrative side (déclarations, aid eligibility, VAT rates) so you don't have to.
Why English-speaking homeowners choose a local artisan, not an online marketplace
Buying an old stone house, a mas or a village property in the Aude is exciting. Getting quotes for the plumbing, the heating or a new roof in a language you don't fully read is not.
Marketplace platforms match you with whoever is available. They rarely check décennale insurance, rarely explain French VAT bands, and disappear the moment there's a dispute. For a British or Irish buyer managing a renovation from abroad, or living in the Aude part-time, that gap is where costly mistakes happen.
Raynier works differently. We are a family-run company based in Carcassonne, trading since 1987, with our own salaried team. When you call +33 4 68 25 45 68, you speak to someone who can walk you through the quote in English, explain what each line means, and stay on the job from the first visit to the Consuel certificate at the end.
How the French building trade actually works
France regulates building work more tightly than the UK in some respects, and more loosely in others. Understanding three things upfront saves confusion later: the quote, the insurance, and the certification.
The "devis": your binding written quote
A devis is a detailed, itemised quote. Once you sign it, it becomes a binding contract at the price stated: no French tradesperson can legally raise the price afterwards for the scope described, barring genuine unforeseen circumstances discovered once work starts (a rotten joist behind a wall, for instance). A serious devis lists materials, labour, VAT rate applied and payment terms separately. Be wary of any quote that is a single lump sum with no breakdown.
The "garantie décennale": ten years of legal cover
Under French law (article 1792 of the Code Civil), any company carrying out structural or waterproofing work, roofing, heating systems tied to the building, or solar installations must hold ten-year (décennale) insurance. It covers major defects that threaten the building's soundness or make it unfit for its purpose, for a full decade after completion. This is not optional and not a marketing add-on: a company without it is operating illegally, and any claim you make later would have nowhere to go. Raynier's décennale cover applies to every plumbing, heating, roofing and solar job we complete.
"RGE" certification: the quality and aid gateway
RGE stands for "Reconnu Garant de l'Environnement" (recognised guarantor of the environment). It is a state-backed certification scheme that checks a company's technical skills for energy-related work: heat pumps, insulation, solar panels, boiler replacement. Two things follow from RGE status. First, it is a genuine quality filter, since the certifying bodies audit installations. Second, in France it is a legal precondition for most energy-renovation financial aid: no RGE certificate, no eligible aid, full stop.
Raynier holds several RGE-recognised qualifications from Qualit'EnR and Qualibat: QUALIBAT RGE (general building quality), QUALIPV (photovoltaic solar), QUALISOL (solar thermal), QUALIPAC (heat pumps) and QUALIGAZ (gas installations), plus a fluide frigorigène (refrigerant handling) certification required by law for anyone servicing air conditioning or heat pump refrigerant circuits.
French renovation terms explained: a plain-English glossary
These are the words you will meet on quotes, invoices and official letters during a French renovation. Bookmark this table.
| French term | Literal meaning | What it actually means for you |
|---|---|---|
| Devis | Estimate | A detailed, binding written quote. Get everything in one, not verbal promises. |
| Artisan | Craftsman/tradesperson | A registered self-employed or company tradesperson, listed at the Chambre de Métiers. |
| Garantie décennale | Ten-year guarantee | Mandatory 10-year insurance on structural, roofing and heating/solar work. |
| RGE | Recognised environmental guarantor | State-audited certification, required to access most energy aid schemes. |
| TVA | Value Added Tax | French VAT, applied at 5.5%, 10% or 20% depending on the work (see below). |
| Attestation TVA | VAT certificate | A form you sign confirming your home's age, so the artisan can apply the reduced VAT rate. |
| Consuel | Electrical safety body | Issues the mandatory conformity certificate for new electrical and solar installations. |
| Déclaration préalable de travaux | Prior works declaration | A simplified planning notice filed at the town hall (mairie) before certain works, including most solar installations. |
| ABF (Architecte des Bâtiments de France) | France's Heritage Architects | Must approve visible exterior work near protected sites, including Carcassonne's medieval Cité. |
| Mas | Farmhouse | A traditional stone farmhouse, common across the south of France. |
French VAT (TVA) rates on renovation work
France applies three VAT rates to home improvement work, and the rate depends on the type of work and the age of the property, not on who is doing the buying. Getting this wrong on a quote either overcharges you or creates a compliance problem down the line.
| VAT rate | Applies to | Conditions |
|---|---|---|
| 5.5% | Energy-efficiency improvements: heat pumps, solar panels (up to 9 kWc with an energy management system), insulation | Home must be over 2 years old; work must be carried out by an RGE-certified company for most schemes |
| 10% | General renovation, repair and maintenance: plumbing repairs, boiler servicing, roof repairs, bathroom refits | Home must be over 2 years old |
| 20% | New-build work, extensions, or renovation on a home less than 2 years old | Standard rate, no age condition applies |
On solar specifically: the reduced 5.5% rate is not automatic. It applies to installations up to 9 kWc on a home over two years old, and only when an energy management system (EMS) is fitted alongside the panels to steer your own consumption. We confirm eligibility during the site visit, before the quote is drafted.
What changed in France's energy rules in 2026
If you researched French solar or heating grants before 2026, some of what you read is now out of date. A decree published on 1 June 2026, effective 5 June 2026, removed the self-consumption bonus for new solar installations and cut the guaranteed surplus buy-back tariff to 1.1 centimes per kWh (source: service-public.fr).
In practical terms: selling power back to the grid is no longer worthwhile at that rate. The strategy that makes financial sense in 2026 is self-consumption: sizing a solar system to match what your household actually uses during the day, so the electricity you generate is the electricity you consume, rather than exported at a token price.
This matters directly for renovators. A holiday home occupied mainly in summer has a very different consumption pattern to a permanent residence, and the right system size follows from that pattern, not from how much roof space is available. It is worth discussing your actual occupancy pattern with your installer before agreeing a kWc figure.
What Raynier handles under one roof
The point of calling one company for a renovation is that the plumber, the roofer and the solar installer are the same team, and they talk to each other before work starts, not after something leaks.
Plumbing and hot water
Full re-piping of old stone houses, often fitted with lead or galvanised steel pipework that needs replacing entirely. Bathroom and kitchen installation, hot water cylinders, and leak detection. Old Aude properties frequently have hard water, which shortens the life of unprotected pipework and appliances.
Heating and heat pumps
Air-to-water and air-to-air heat pumps (QUALIPAC certified), gas boiler installation and servicing (QUALIGAZ certified), underfloor heating, and radiator systems suited to thick stone walls with irregular insulation, a common challenge in older mas and village houses.
Air conditioning
Split-system and multi-split air conditioning, sized for the Aude's hot, dry summers. Fitted and serviced by technicians holding the mandatory fluide frigorigène (refrigerant handling) certification.
Roofing and zinc work
Traditional roofing repair and replacement, zinc guttering and flashing, a trade with deep roots in French building heritage, especially relevant for period stone properties where the roof structure and covering need specialist, not generic, attention.
Solar
QUALIPV-certified photovoltaic installation, sized around your real consumption rather than your roof size. Carcassonne enjoys more than 2,400 hours of sunshine per year (source: PVGIS, European Commission), among the highest solar resource levels in mainland France, which makes a well-sized self-consumption system genuinely productive here.

A pre-purchase checklist for stone houses and mas properties
Before or just after completion on an Aude property, these are the checks worth running so surprises don't wait for winter.
- Ask for the diagnostics report (DPE and related surveys) handed over at sale: it flags the property's energy rating and known issues.
- Have the plumbing inspected before your first winter: old lead or galvanised pipework in stone houses fails without warning.
- Check the heating source: many older Aude houses still run on oil or ageing electric convectors; a heat pump quote is worth getting even if you're not ready to commit.
- Inspect the roof from inside the attic, not just from the ground: daylight through old tiles or damp rafters is a warning sign.
- Confirm any prior work has décennale insurance documentation: ask the seller for invoices and insurance certificates for recent renovation work.
- If you're considering solar, get your consumption pattern clear first: a holiday-use pattern needs a different system size to full-time occupancy.
FAQ: English-speaking plumber and solar installer in the Aude
Do I need to speak French to get a quote from Raynier?
No. Call +33 4 68 25 45 68 and we will talk you through the site visit, the devis and every technical term in English before you sign anything.
What is a "garantie décennale" and why does it matter for my renovation?
It is a legally mandatory 10-year insurance covering structural and major defects on building, heating, roofing and solar work in France. Any company without it is not operating legally, and you would have no recourse if a defect appeared later. Every job Raynier completes is covered.
Is RGE certification the same as a UK trade qualification?
Not quite. RGE is a French state-backed certification that audits a company's technical competence on energy-related work, and it is also the legal gateway to most French renovation grants and reduced VAT rates. Raynier holds QUALIBAT RGE, QUALIPV, QUALISOL, QUALIPAC and QUALIGAZ certifications.
Can I still sell solar electricity back to the grid in France in 2026?
Technically yes, but the surplus buy-back tariff was cut to 1.1 centimes per kWh from 5 June 2026, making it financially marginal. The sensible approach now is to size a solar system for self-consumption: covering your own daytime usage rather than exporting cheaply.
What VAT rate applies to renovating an old French stone house?
Most repair and renovation work on a home over two years old is charged at 10% VAT. Energy-efficiency work such as heat pumps or solar (up to 9 kWc with an energy management system) can qualify for the reduced 5.5% rate. New-build or work on homes under two years old is charged at the standard 20%.
Does Raynier subcontract any of the work?
No. Raynier employs its own team of 20 tradespeople directly, covering plumbing, heating, air conditioning, roofing, zinc work and solar. The same company that quotes the job carries it out and stands behind it under décennale insurance.
How much sunshine does the Carcassonne area actually get for solar?
Over 2,400 hours of sunshine per year, according to PVGIS data from the European Commission, one of the highest levels in mainland France. That makes a correctly sized self-consumption solar system genuinely worthwhile for full-time or well-used holiday homes.
What areas around Carcassonne does Raynier cover?
Carcassonne and the wider Aude department, including Trèbes, Pennautier, Limoux, Castelnaudary, Narbonne and Lézignan-Corbières. Call to confirm coverage for your specific village.
