Financing calculator
Most retrofits are not a cost question but a cash-flow question. Model the instalment against the saving and see whether the plan pays for itself from month one.

Savings cover 36% of the instalment; the remainder is your net monthly outlay.
All figures shown are indicative estimates generated from standardised building models and average market prices. They are not a certified energy performance assessment, an engineering report, or financial advice. Actual savings, costs, subsidies and payback depend on an on-site assessment of your property.
Subsidies first
Eligible measures typically attract around 25% support, capped near €30,000 per property. We net this off before financing.
Terms that match asset life
Choose 2–20 years. Longer terms lower the instalment and usually flip the plan cash-flow positive sooner.
Verified before drawdown
An on-site assessment confirms scope and price, so the financed amount reflects a fixed quotation rather than an estimate.
