Home retrofitted for year-round thermal comfort

Real
comfort, all year.

Thermal comfort

A poorly insulated home leaks heat through the façades, the roof and the joints. The result: sky-high bills, uneven temperatures and a heavy carbon footprint. The EnerPHit standard brings comfort back without stripping the building of its character.

Verifiable savings

PAPIK Group assesses, designs, handles the grant application and builds. With our own bridge financing, in most cases the owner puts up no capital. A drop in energy use that we prove with a Blower Door test and Passivhaus EnerPHit certification.

Asset revaluation

An EnerPHit retrofit lifts the building's standing in the market: A rating, MVHR system, ventilated façades. You get the investment back in resale value and in lower bills every month.

Three grant levels

The grant percentage tracks the real energy improvement. The lower the building's heating and cooling demand, the more non-repayable funding you get. PAPIK Group models all three scenarios in the free assessment to guide the technical and financial call.

Calls, deadlines and financing

PRTR programmes run until December 2026, with a budget topped up each year. PAPIK Group checks every technical and documentary requirement before filing, and offers its own bridge financing, so in most cases you never front the money at any point.

Our process

Managed from start to finish

A clear process that PAPIK Group runs from day one. You always know where your file stands, and you never front the money at any stage.

Phase 01 | Assessment

Technical assessment and audit

Thermography, an initial blower door and a read on your current consumption. You get a full energy report with proposals for improvement.

Phase 01: Assessment 2–4 weeks
Phase 02 | Paperwork

Preliminary design and grant

We draft the preliminary design and put together every document for the Next Generation EU call. All without you fronting a euro.

Phase 02: Paperwork 4–8 weeks
Phase 03 | Project

Detailed project and permits

A detailed technical project, the municipal permits handled for you and a final sign-off with the architect in charge.

Phase 03: Project 4–6 weeks
Phase 04 | Execution

Works with the Eskimohaus® system

We carry out the retrofit with our own building system. Minimal disruption, every step planned and documented.

Phase 04: Execution 4–12 months
Phase 05 | Verification

Blower Door and certification

Airtightness test n50 ≤ 1 ach/h, EnerPHit certificate and final energy label. Verifiable results.

Phase 05: Verification 2–3 weeks
Phase 06 | Justification

Grant settlement

We file the paperwork with the granting body and chase the payment. The grant lands straight in your account.

Phase 06: Justification 4–8 weeks
Frequently asked questions

Common questions about retrofit

01

How much does it cost to retrofit my home to the EnerPHit standard?

The indicative cost ranges from 600 to 1,200 €/m² depending on the scope (envelope, roof, systems, certification). With a Next Generation EU grant it can drop to 200-500 €/m² net for the owner. PAPIK Group provides a detailed estimate in the free assessment.

02

Who can apply for the Next Generation EU grants?

Any owner or homeowners' association of an existing residential building can apply for the PRTR grants. There is no income limit.

03

Do I have to advance money for the works?

In most cases, no. PAPIK Group offers bridge financing: we cover the cost up front and you settle once the grant reaches your account, interest-free. If the scope of the works exceeds the expected grant, we size it and agree it in writing before the contract is signed.

04

How long does the paperwork process take?

Application to resolution: 3–6 months. Total process from the first meeting to the final certification: 10–18 months.

05

Do I need my own architect?

No. PAPIK Group provides the complete technical team (architect, industrial engineer, energy certification specialist). If you already have a trusted architect, we collaborate with them at no additional cost.

06

Is my building too old?

Any residential building built before 2007 is eligible, and the older it is, the more room for improvement and the larger the grant. Buildings from the 1960s to the 1980s achieve the biggest energy jumps.

07

Can a home be retrofitted without moving out?

It depends on the scope. Façade and roof work happens while you stay put (just some noise during working hours). A full interior retrofit means moving out for 4–8 weeks. We plan it all in the assessment.

08

What real savings can I expect?

1970s buildings that move up to A typically reduce heating consumption by 75–90%. Partial retrofit: 40–60%. PAPIK Group always presents detailed estimates with temperatures, bills and projected ROI.

09

Does my homeowners' association need unanimity?

No. For energy improvement works, Spanish condominium law (Ley de Propiedad Horizontal) allows approval with the favourable vote of one third of the owners. PAPIK Group advises the board and prepares the technical documentation for the vote.

10

What happens if the grant is not finally approved?

PAPIK Group won't start the works until alternative financing is in place (green bank, ICO, your own capital). Nothing begins without a confirmed way to pay. And if the grant never comes through, we scale the project to fit your real budget.
