Window subsidies 2026: PNRR "Energy Efficient Home" and which programme covers joinery

Many homeowners in Bucharest and Ilfov postpone replacing their windows because they assume they must bear the entire cost themselves. In 2026, however, there are real funding programmes through which the state and European funds cover a significant part — sometimes even 100% — of the cost of thermally insulating joinery. The most relevant programme for window replacement is the PNRR "Energy Efficient Home" (RePowerEU). This guide explains exactly which programme covers windows, what amounts you can obtain and how it combines with the other support schemes.

The programme that actually funds window replacement in 2026

The main programme covering the replacement of exterior joinery is the PNRR — National "Energy Efficient Home" Programme, part of the RePowerEU component. Unlike Casa Verde (which targets photovoltaic panels), this programme directly funds the energy renovation of the home's envelope — including replacing exterior windows and doors with high-performance thermally insulating joinery.

The voucher value can reach approximately 72,500 lei per dwelling, and for a single-family residential building the non-reimbursable value was set at around EUR 20,200 (roughly 100,513 lei). The funding rate can reach 100% of eligible costs, meaning that in certain situations the beneficiary does not have to contribute anything towards the eligible works.

> Essential condition: the renovation must achieve a minimum 30% reduction in the home's energy consumption. Replacing old windows with high-performance thermally insulating joinery contributes significantly to reaching this threshold.

PNRR "Energy Efficient Home" — the two axes

The programme is structured along two axes, depending on the beneficiary profile:

A beneficiary can only be funded through one of the two axes, to respect the principle of avoiding double funding. Eligible works include thermal insulation of walls and façade, replacement of exterior joinery with thermally insulating joinery (windows and doors), as well as other interventions that increase energy efficiency.

The role of each funding programme

There is frequent confusion between programmes. Here, in short, is what each is for:

The practical conclusion: if your goal is window replacement, the programme to follow is PNRR "Energy Efficient Home". Casa Verde remains useful for those who want solar panels, and some city halls offer complementary local schemes.

Documents needed for the application

The documentation varies from session to session, but generally you need an identity document, the land registry extract proving ownership, the fiscal attestation certificate (no debts to the state and local budget), a detailed offer from an authorised company and, in many cases, an energy performance certificate for the building. To understand how windows fit into the energy assessment, you can read What thermal coefficient should windows have.

How to prepare in advance

Enrolment sessions have limited funds and can be exhausted quickly. The practical recommendation is to have your documentation ready before the call opens and a valid technical offer from an authorised supplier. A correct offer includes the technical specifications of the proposed joinery — the Uw coefficient, the glazing type, the profile — so the auditor can calculate the consumption reduction.

FAQ — Window subsidies 2026

Which programme covers window replacement in 2026?

The main programme is PNRR "Energy Efficient Home" (RePowerEU), which directly funds the replacement of exterior joinery with thermally insulating joinery, with vouchers of up to around 72,500 lei and funding of up to 100% of eligible costs.

Does Casa Verde cover window replacement?

Not directly. The Casa Verde Photovoltaics programme targets solar panels, and Casa Verde Plus refers to insulation with organic materials. For windows, the appropriate programme is PNRR "Energy Efficient Home".

How much can I obtain for my home's energy renovation?

For a single-family residential building, the non-reimbursable value was set at around EUR 20,200 (roughly 100,513 lei), with a funding rate that can reach 100% of eligible costs, depending on the axis and session conditions.

What condition must the renovation meet?

The renovation must achieve a minimum 30% reduction in the home's energy consumption. Replacing old windows with high-performance thermally insulating joinery contributes significantly to reaching this objective.

Can I combine several programmes?

You cannot be funded twice for the same work through different axes of the same programme. However, under certain conditions, you can combine renovation funding with local schemes or green bank loans for the non-contracted part.
