What do thermostat installation services include?

Whether you want to replace your old thermostat due to old age, or simply because you found a more advanced model, installers can handle the entire setup and installation process for you. You can get help with almost any type of thermostat, regardless if it's programmable or non-programmable, wired or wireless, or smart.  

If you have yet to purchase one, your Tasker can also help you find the best thermostat that suits your needs. Utilising their technical expertise for the job, you can expect a quicker turnaround time without compromise. Here's what you can expect:

Removing the old thermostat

When removing the old thermostat, make sure to turn off your HVAC units, either from the electrical breaker box or by switching off the system. The purpose is to limit potential hazards while accessing the wires and circuits. 

Your Tasker usually starts by removing the old front plate. Before they disconnect the body, they keep the wires labelled and identified to make it easier to reconnect the new thermostat later on. Then, they unscrew the old mounting plate from the wall.

Need help with disposing of your old thermostat? Unlike regular trash, they shouldn't simply go to your kerbside collection. Instead, you can hire a clearance specialist to collect them and hand them over to a hazardous waste drop-off site. 

Fitting the new thermostat

Taskers follow the recommended installation steps from the manufacturer. Usually, it starts by connecting the new plate on the wall and then reconnecting the labelled wires in their corresponding terminals. All excess and loosened wires are then pushed back into the wall. The last step is the mounting of the cover plate.

With a properly installed thermostat, it should be easier to maintain an ideal indoor temperature without the need to leave your AC on full blast. But if you want to cut down your energy and electrical consumption, you might also want to consider insulating your room through walls or ceilings.

Configuration and final testing

To confirm the success of the installation, you need to turn the power back on and reset the setting of your new thermostat. Your Tasker can help you program the unit as per the user manual. If you're using a smart thermostat, they can connect them to your wireless network and then try controlling from a third-party device, like a smartphone or tablet. Once done, set the desired temperature of your HVAC unit and check if they are heating or cooling the space as required.

Replace Thermostatic Mixer Shower Valve and Adjust Temperature Limit

£50

Finsbury Park, Greater London, N4

14th Mar 2026

I need a plumber or experienced handyman to service my concealed thermostatic shower mixer. Tasks required: 1. Remove Handle & Faceplate: Carefully remove the matte black temperature handle and faceplate (as seen in the photo). 2. Clean Limescale/Corrosion: There is some buildup and pitting around the base of the handle. I need this cleaned up as much as possible without damaging the finish further. 3. Adjust Temperature Limit: The shower does not get hot enough. I need you to recalibrate the internal thermostatic cartridge/stop ring to allow for a higher maximum temperature (past the current 38°C limit). 4. Inspect for Leaks: Check if the white buildup is caused by a slow leak from the cartridge seals and advise if a new O-ring is needed. Notes: * I am not looking to replace the unit, just to have it serviced and the heat limit adjusted. • Please bring appropriate tools (allen keys/wrenches) and a descaling solution.
