What financial aid is available for bathroom renovation in Belgium?

Renovating a bathroom represents a significant investment, but did you know that there are specific financial aids in Belgium that can help reduce the cost of your work? Certain grants or reduced VAT rates may apply depending on the nature of the renovations, your region, and the condition of your home.

Regional renovation aids (Wallonia, Brussels, Flanders)

In Belgium, housing-related competencies are regionalized. This means that each region offers its own renovation aid schemes.

1. Wallonia: Housing Grants

The Walloon government offers Housing Grants, accessible to owner-occupiers, landlords, or tenants under certain conditions. These grants can cover common interventions in a bathroom:

Replacement of a bathtub with a walk-in shower (accessibility)
Safety improvement work (electricity, ventilation)
Interior fit-out for persons with reduced mobility (PRM)

Amount: variable depending on your income, household composition, and the nature of the work. A prior energy audit may be required in some cases.

Reference: energie.wallonie.be

2. Brussels-Capital: RENOLUTION Grants

The Brussels region offers the Renolution scheme, which consolidates all previous renovation and energy grants.

The aids specifically cover:

Plumbing and sanitary work
Improvement of ventilation
PRM work
Bringing up to technical standards

The amount of the grant depends on three criteria: your income, the location of the property, and the nature of the work.

Reference: renolution.brussels

3. Flanders: Mijn VerbouwPremie

In Flanders, the Mijn VerbouwPremie (My Renovation Grant) covers many types of work, including those related to the bathroom, particularly in the context of adapting the home.

The amount depends on the household income and the nature of the work. The Flemish simulator allows you to assess eligibility online.

Reference: www.premiezoeker.be

Reduced VAT rate for homes over 10 years old

In addition to regional grants, you can also benefit from a reduced VAT rate of 6% on your renovation work, under certain conditions.

Main conditions:

The property is residential and over 10 years old
The work is carried out by a registered company in Belgium
The building is intended mainly for private housing
A written certificate is provided to the contractor

This reduced rate applies to:

Labor costs
Material supplies (in certain cases)
Services associated with the renovation (removal, disposal, adaptation)

This can represent a significant saving compared to the normal rate of 21%.

Our team can help you identify regional aids and benefit from the correct VAT rate. During the free technical visit, our franchisees will advise you on the administrative procedures and documents to provide.
