Price-determining factors for installing a thermostat
The costs for installing a thermostat vary per situation. Not all installations are the same: one job requires more time and material than another. Below you can read which factors influence the price and why.
Type of thermostat
A mechanical thermostat costs between €15 and €35 and usually has standard wiring. A smart thermostat costs between €200 and €300 and often requires extra configuration time. Some smart models need a C-wire (common wire) for constant power. If that wire is missing, the professional must install extra wiring. This increases labour costs by an average of half an hour to an hour.
Condition of the existing wiring
When replacing, the existing wiring is usually directly accessible. The professional can remove the old thermostat and connect the new one without extra work. If the wiring is damaged or outdated, it must first be repaired or replaced. This requires extra material and labour time, which increases the costs.
Complexity of the installation
Installing a thermostat in new builds is faster than in existing buildings. In new builds, the wiring is often already prepared and the wires are visible or easily reachable. Moving a thermostat to a different location means pulling new wiring through walls or ceilings. This significantly increases labour costs.
Compatibility with the heating system
Smart thermostats that communicate with central heating boilers, heat pumps or underfloor heating sometimes require knowledge of both electricity and heating systems. Not all thermostats work directly with every system. In complex installations, it may be necessary for both an electrician and a heating engineer to be involved, which increases the price.
Number of thermostats
If you have multiple thermostats installed at the same time, the costs per unit are lower. The professional only comes once and can perform several installations in succession. This saves travel time and preparation time.
Emergency versus planned work
Emergency jobs cost more than planned work. A professional must adjust their schedule to be immediately available. This entails extra costs. Plan the installation ahead to avoid these additional charges.
Weekend or evening work
Work on the weekend or in the evenings costs more than during the week during the day. Hourly rates are higher outside regular working hours.
Region
In large cities, the costs to have a thermostat placed are often higher than in rural areas. This is due to higher hourly rates and higher operating costs for professionals in urban regions.
Accessibility of the workplace
Installing a thermostat is faster if the workplace is easily accessible. If the professional first has to move furniture or work through a tight space, it costs extra time.
Preparation by the customer
Good preparation saves time. Take photos of the old wiring before removing the thermostat. Ensure that the power can be safely switched off. The better the preparation, the faster the professional can work.
Choice of a local professional
Local professionals often charge less travel time and can be on site faster. This reduces the total costs for the installation.

How does the professional work when installing a thermostat?
The installation follows a fixed sequence of steps.
- Preparation: The professional switches off the power at the consumer unit to work safely. When replacing, the old thermostat is removed and the wires are identified and labelled for correct connection.
- Attaching the mounting plate: The mounting plate is attached to the wall at the desired location. The professional checks if the plate is level and securely fixed.
- Connecting the wiring: The wires are connected according to the manufacturer's diagram. With a smart thermostat, a C-wire may be needed for continuous power. If this is missing, the professional installs extra wiring.
- Configuration and testing: The power supply is restored. The professional tests the operation of the thermostat and programmes it according to your wishes. With smart thermostats, the Wi-Fi connection is set up and checked.
- Completion: The professional checks whether the heating system responds correctly to the thermostat. The average installation time is two hours or less for a standard replacement. The costs include all testing and configuration.
How can you save on installing a thermostat?
There are several ways to save on the costs of installing a thermostat.
- Replace in a timely manner: Replace an outdated or defect thermostat before it fails completely. A poorly functioning thermostat leads to unnecessary energy consumption and higher heating costs, which offsets the savings of a new installation.
- Prepare the workplace: Clear the area and make it accessible before the professional arrives. Take photos of the existing wiring and check if the Wi-Fi range is sufficient for smart thermostats. This prevents the professional from having to spend extra time on preparation.
- Plan smart: Plan the job during the week and not as an emergency. Weekend work and emergency jobs increase costs. Combine multiple jobs or thermostats to save on travel costs.
- Choose compatible: Choose a thermostat that is compatible with your current heating system. This prevents unexpected extra costs through additional adjustments to the wiring or the system.
- Book via Zoofy: You get a fixed rate in advance, without call-out charges and without surprises. You only pay after completion of the job.
Common causes for thermostat replacement
Problems with thermostats have various causes that can lead to replacement.
Defective or outdated components
The thermostat no longer responds, freezes or shows no display. Incorrect temperature measurements that make it too warm or too cold are also common complaints. The heating does not start or stop at the right time, leading to uncomfortable temperatures and higher energy costs.
Connection problems with smart thermostats
Smart thermostats can have issues with the Wi-Fi connection or turn out to be incompatible with the heating system. Outdated software can limit functionality. These problems often require replacement or an upgrade to a suitable model.
Incorrect or outdated wiring
In older homes, the existing wiring may be unsuitable for modern thermostats. This requires replacement or adjustment of the cabling, which increases the installation costs.
