Why the rate is lower than a personal loan

The purpose is documented and the money goes into a property. That lowers the lender's risk, and the discount comes back to you in the rate.

The gap is not cosmetic. Between a personal loan and a renovation loan, Belgian lenders routinely sit several percentage points apart — on €25,000 over seven years that difference runs well past €2,000.

What it costs you is paperwork: quotes before the loan, invoices after it. Some lenders release the money in tranches against invoices rather than in one payment, which is worth knowing before you sign a contract with a builder.

Regional energy loans come first

All three Belgian regions run subsidised loan schemes for energy work — insulation, glazing, heat pumps, boilers, solar. The rates sit far below the commercial market and several are zero-interest for households under an income ceiling.

The schemes are capped in amount and restricted in scope: they finance the energy work, not the new kitchen. Where your project mixes both, the usual answer is a regional loan for the energy part and a commercial loan for the rest.

They also run on their own timetables and budgets, and conditions change from one year to the next. Check the current terms with your region before assuming last year's rules still hold.

Renovation loan or mortgage top-up

If you already hold a mortgage, your bank may offer to increase it rather than write a separate loan. The rate is usually lower, because the property secures it.

The catch is cost and duration. A mortgage increase involves notary fees and mortgage registration, which a renovation loan does not, and it stretches the debt across the remaining mortgage term — twenty years of interest on a new bathroom is rarely the cheaper answer.

The rule of thumb: for large structural work, the mortgage route can win despite the fees. For anything you would repay in under ten years, the renovation loan almost always does.

Our verdict

Before comparing banks, check whether your region already lends you the money cheaper. Flanders, Wallonia and Brussels all run energy-renovation loan schemes at rates no commercial lender matches, and several are interest-free for eligible households. The bank comparison below is what you do after that door closes, not before you knock.

Frequently asked questions

What is the cheapest renovation loan in Belgium?

For energy work, almost always a regional scheme rather than a bank: Flanders, Wallonia and Brussels all lend below market rate, some interest-free. Among commercial lenders, published APRs in our survey run from 3.55% to 7.45%.

What work qualifies for a renovation loan?

Work on a home you own or occupy: insulation, heating, roofing, windows, electrics, bathrooms, kitchens, extensions. Lenders ask for quotes beforehand and invoices afterwards. Furniture and appliances usually fall outside the definition and need a personal loan instead.

Is a renovation loan cheaper than a personal loan?

Yes, typically by several percentage points in Belgium, because the purpose is documented and the money goes into a property. On €25,000 over seven years that difference exceeds €2,000 in interest — for the cost of keeping your quotes.

Should I increase my mortgage instead?

For large structural work, possibly: the rate is lower because the property secures it. But notary and registration fees apply, and the debt stretches over the remaining mortgage term. For anything repayable within ten years, a renovation loan usually costs less overall.
