MaPrimeRénov’ purple: the flat rate the cap eats into

The calculator is set to 3 people and €50,000 reference tax income outside Île-de-France: the purple band. Watch the “cut” line.

Purple households have “middle” incomes: for three people, from €39,149 to €55,196 of reference tax income outside Île-de-France, up to €71,846 in Île-de-France. In 2026 MaPrimeRénov’ grants them a flat rate of €3,000 for an air-to-water heat pump and €6,000 for ground-source. This band is the hardest hit by the cap: total grants cannot exceed 60 % of the eligible expense, and the CEE bonus with Coup de pouce, even at the standard price, already takes a large share. On a €9,000 air-to-water quote in the Rhône, the €3,000 flat rate falls to €590. The higher the quote, the higher the ceiling and the smaller the cut; but the out-of-pocket cost rises too. What matters is the out-of-pocket cost, not the advertised sum of grants.

Outside Île-de-France ceilings for 3 people: blue ≤ €30,540, yellow ≤ €39,148, purple ≤ €55,196. Estimate only: the Anah alone sets the grant, and the CEE amount is the one the firm puts in writing before you sign.

Grants and out-of-pocket cost for a purple household

Site calculation: 100 m² house in the Rhône (zone H1), gas boiler replaced, 3-person household, reference tax income €50,000, cap applied; hypothetical quotes except the published air-to-water median

Ground-source, €24,000€5,434€5,366€10,800€13,200

The table shows the effect of the 60 % ceiling: whatever the quote, the household pays at least 40 % of the eligible expense, plus everything above the expense ceiling. The full formula is on the grant cap page.

The 2027 plan

The 2027 draft budget, not yet voted, plans for heat pumps to be funded solely through CEE. For a purple household whose MaPrimeRénov’ is already largely cut, the difference would be small; for a blue household it would be sharper. This is still to come and may change during the parliamentary debate.

Other levers

5.5 % VAT on the heat pump and its fitting in a home over two years old, and the zero-rate eco-loan to spread the out-of-pocket cost without interest.

Frequently asked questions

Should I give up MaPrimeRénov’ when it is almost entirely cut?

A MaPrimeRénov’ application takes time: account creation, quotes, approval before work, invoice. If the calculator shows only a few hundred euros left after the cap, it is your call whether that is worth the effort. The CEE bonus is due in every case and must be accepted before signing the quote.

Why is my CEE bonus lower than a yellow household’s?

Work by purple households generates standard certificates, sold at an average €8.82 per MWh cumac in September 2026 on the Emmy registry, against €14.64 for the fuel-poverty certificates of blue and yellow households. The kWh cumac volume itself is the same for everyone.

Is ground-source a better deal for a purple household?

Its flat rate is double (€6,000) and its expense ceiling higher (€18,000), so the cap bites less in proportion. But installation costs much more. Compare the out-of-pocket cost and yearly saving of both options in the calculator, with your quotes.
