Regulations on individual meters
In Belgium, the legislative trend clearly favours the individualisation of meters in apartment buildings. The aim is twofold: to make each occupant responsible for their consumption and to avoid disputes over the allocation of rental charges.
| Energy | Individual meter obligation | Note |
|---|---|---|
| Electricity | Near-systematic | One meter per housing unit |
| Gas | Variable | Depends on the Region and building type |
| Water | Being generalised | Progressive obligations by Region |
| Heating | Heat cost allocator mandatory (certain cases) | Buildings with collective heating |
For the landlord, installing individual meters considerably simplifies charge management and reduces disputes. A property with individual meters also rents out more easily.
Electricity meters
Each dwelling must have its own electricity meter with a distinct EAN number. This is the standard for nearly all dwellings in Belgium.
In the case of a building subdivision (creation of a new apartment), the landlord must request a new connection from the distribution network operator (GRD). The cost ranges from EUR 500 to 2,000 depending on the complexity.
If a single meter serves multiple dwellings (older situation), the landlord has two options:
- Install a meter per dwelling (ideal solution)
- Install sub-meters and include an allocation formula in the lease
Smart meters are becoming widespread and facilitate individual consumption tracking.
Individual water meters
The obligation for individual water meters is evolving rapidly:
| Region | Obligation | Timeline |
|---|---|---|
| Brussels | Mandatory (new connections) | In force |
| Wallonia | Mandatory (new buildings and renovations) | Progressive |
| Flanders | Mandatory (new buildings) | In force |
For existing buildings without individual water meters, the landlord can:
- Install sub-meters in each dwelling
- Allocate the total bill using a distribution formula (shares, number of occupants)
- Include water in a flat-rate charge (less transparent)
Installing a water sub-meter costs between EUR 200 and 500 per dwelling. It is a worthwhile investment that eliminates disputes over water charge allocation.
Gas meters
An individual gas meter is generally present in buildings where each dwelling has its own heating system. For buildings with collective heating (a single boiler for the entire building), gas is measured by a shared meter.
In this case, allocation is done via:
- Heat cost allocators (calorie meters) on each radiator
- A distribution formula based on shares
- An individual metering system on the heating circuit
In co-ownership, the installation of heat cost allocators is decided by the general assembly. The landlord passes on heating costs to the tenant via the annual charge settlement.
In practice for the landlord
Check what exists. Before letting, identify the available meters (electricity EAN numbers, water and gas meters). Mention them in the entry property inventory.
Favour individual meters. Every euro invested in meter individualisation results in fewer disputes, better charge management and a property that is more attractive to tenants.
Include a clause in the lease. If meters are shared, the allocation formula must appear in the lease or its annexes. Be precise: basis of allocation, frequency of settlement, adjustment method.
Record meter readings. At each tenant entry and exit, record all meter readings (electricity, gas, water). Smart meters automate this task.
A rental management software centralises meter readings, charge settlements and records for each property.
