Average costs of gas, water and electricity
The costs for gas, water and electricity average €150 per month for an average home. This amount consists of three components: gas (€100 per month), electricity (€30 per month) and water (€25 per month). Total costs vary between €100 for an apartment and €200 for a detached house.
Average gas costs per house type
| Type of dwelling | Costs per month |
|---|---|
| Apartment | €100 |
| Terraced house | €130 |
| Corner house | €150 |
| Semi-detached house | €160 |
| Detached house | €200 |
| Average for all house types | €135 |
Gas costs are the largest expense and are directly related to the size of your home. Larger homes with more exterior walls lose more heat and therefore require more heating energy.
Average electricity costs per household
| Type of household | Costs per month |
|---|---|
| Single-person household | €17 |
| Two-person household | €30 |
| Three-person household | €50 |
| Four-person household | €65 |
| Five-person household | €56 |
| Average per household | €30 |
The costs for gas, water and electricity for one person are considerably lower than for larger households. With electricity, there is a clear increase as there are more residents, although five-person households are on average slightly more economical due to economies of scale.
Average water costs per household
| Type of household | Costs per month |
|---|---|
| Single-person household | €10 |
| Two-person household | €15 |
| Three-person household | €20 |
| Four-person household | €30 |
| Average per household | €25 |
Water costs remain relatively limited compared to gas and electricity. The costs for gas, water and electricity for two people average €150 per month (€135 gas + €30 electricity + €15 water), while a single-person household averages approximately €130 per month. All mentioned prices include 21% VAT and other levies.
Gas, water and electricity costs per house type and household size
The costs for gas, water and electricity differ greatly per house type and household size. An apartment has the lowest gas costs (€100 per month), while a detached house is the most expensive (€200 per month).

Factors determining the price of gas, water and electricity
The costs for gas, water and electricity vary significantly per situation. These differences are the result of concrete factors that determine your consumption.
Type of dwelling
A detached house has exterior walls on all sides that lose heat. A terraced house shares two walls with neighbours and therefore loses less heat, resulting in lower energy costs.
Insulation of the dwelling
Well-insulated walls, roofs and floors keep heat inside. Better insulation means your boiler has to run for a shorter time to maintain the same temperature.
Number of residents
More residents mean more showering, more frequent washing, more cooking and lighting on for longer. Every appliance and tap usage increases electricity and water consumption.
Heating period and season
In winter months, your heating is on for hours daily, while in summer you mainly use hot water. The length and severity of the winter directly affect your annual energy costs.
Type of energy contract
With a fixed contract, you pay a set price per kilowatt-hour. Variable and dynamic contracts follow market prices and require conscious usage during cheaper hours.
Direct and indirect factors
- Energy tax and levies: Fixed components like energy tax, network costs and VAT.
- Regional differences: Network tariffs determined by your regional operator.
- Complexity of installations: Older boilers are less efficient than modern condensing boilers.
- Behaviour and awareness: Lowering the thermostat by one degree and shorter showers save costs.
Additional costs and surcharges
On top of the energy costs themselves come fixed levies and network costs. At Zoofy, you do not pay call-out charges when you hire a professional for insulation work or boiler maintenance.
- Network costs: Fixed costs paid to the network operator for transport.
- Municipal levies: Sewerage, waste collection and water board taxes.
- Standing charge: A fixed monthly amount charged by energy suppliers for the connection.
- Urgency surcharge: May apply for urgent jobs through Zoofy.
- Weekend surcharge: Work at weekends is more expensive than during the week.
How to analyse your own energy consumption
Analysing your energy consumption helps you gain insight into your costs for gas, water and electricity.
- Collect your consumption data: Check your last annual statement.
- Compare with averages: Use the tables above to see where you stand.
- Check your energy label: A low label means insulation measures could offer high savings.
- Create an action plan: Prioritise insulation or a smart thermostat.
- Compare energy suppliers: Check rates and contract types.
- Carry out insulation: Book a professional via Zoofy without call-out charges.
How to save on gas, water and electricity
- Insulation: Cavity wall, roof or floor insulation provides the greatest savings.
- Smart thermostat: A degree lower saves 7% on energy costs.
- High-efficiency boiler or heat pump: Replace outdated systems for better efficiency.
- Shorter showers: Reduces both water and gas costs.
- Turn off appliances: Prevent standby consumption with a power strip switch.
- Book via Zoofy: Fixed rates, no call-out charges and payment after completion.
Common causes of high energy costs
Poor insulation
Uninsulated walls and roofs lead to massive heat loss, forcing the boiler to run continuously.
Outdated boiler
Old boilers can consume up to 30% more gas than modern high-efficiency models.
Phantom power
Appliances in standby mode add up to significant unnecessary electricity costs annually.
