Which renovations really increase the value of your property in Belgium?
By Gaëtan Lefebvre · Immobilière B2 · Lasne, Brabant Wallon
Before putting your property on the market in Lasne, Uccle, Ixelles or Waterloo, one question often arises: is it better to renovate before selling, or sell as is? And if you decide to renovate, which works really pay off at resale?
The answer is not universal. Everything depends on the type of property, its location and the local market. Here is the complete guide by Immobilière B2 to help you make the right choices.
1. Thermal insulation and EPC: the best return on investment
In 2025-2026, the EPC certificate has become a major buying criterion. A property with an EPC rating of A or B sells faster and at a higher price — sometimes 10 to 20% more than an identical property with an F or G rating.

2. The kitchen: the heart of the home
A renovated kitchen is one of the most powerful selling arguments. In high-end markets like Lasne, Uccle or Genval, a beautiful fitted kitchen can justify an added value of €15,000 to €40,000.
Note: there is no point investing in a luxury kitchen if the rest of the house is in poor condition. Balance between rooms is essential.
3. The bathroom: an investment that pays
A modern, well-equipped bathroom is a decisive criterion for many buyers. A carefully renovated bathroom (walk-in shower, double washbasin, modern tiling) can bring an added value of €8,000 to €20,000 depending on the property's standard and location.
4. Electrical compliance: mandatory and value-adding
In Belgium, a non-compliant electrical installation is a major obstacle to a sale and can lead to a significant price reduction. Compliance is mandatory and immediately reassures buyers.
Average cost: €3,000 to €8,000 depending on size · Return: avoids a price reduction of €10,000 to €30,000.
5. Works that are NOT worth the investment before a sale
Our advice: ask an expert before renovating
Before investing in works, request a valuation of your property as it stands. Immobilière B2 can advise you on which works will provide the best return on investment in your area — and which are not worth it. This advice is free and with no obligation.
