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.

Task: Diagnose and Replace Wireless Thermostat – Glow-worm Boiler

£100

Noel Park, Greater London

18th Oct 2026

Task: Diagnose and Replace Wireless Thermostat – Glow-worm Boiler I have a Glow-worm Ultimate 30c combi boiler with a wireless thermostat that has stopped working reliably. The thermostat screen is intermittently blank, and the heating won’t come on when the display isn’t working. I’ve replaced the batteries and completed basic troubleshooting, but the issue persists. I suspect the thermostat needs replacing, potentially along with the receiver. I’m looking for a qualified heating engineer who can: * Advise on which replacement thermostat and receiver to purchase, ensuring compatibility with my boiler. * Check whether both components need replacing. * Install and pair the new equipment, and test the heating. I can purchase the recommended equipment in advance once compatibility is confirmed.

Diagnose wall thermostat/controller not communicating with HIU

£50

Balham, Greater London

21st Sep 2026

I’m looking for an experienced heating/HIU engineer to diagnose an issue with the heating controls in my flat. I have an HIU (Heat Interface Unit) and a wall-mounted heating controller/thermostat. The wall controller does not appear to be communicating with the HIU correctly — changing the heating settings/turning the heating on does not seem to trigger the HIU or radiators. The HIU has previously had a faulty actuator valve head replaced. The previous engineer replaced the actuator and got the heating working, but I don't think the wall controller/controls were properly investigated. I therefore need someone who understands BOTH: HIUs / Heat Interface Units Heating thermostats, programmers and control systems The communication/connection between the wall controller, receiver/relay and HIU Electrical/wiring diagnosis where appropriate I’m looking for someone to diagnose the actual fault rather than simply replace the actuator again. Please only apply if you have experience with HIUs AND heating controls/thermostats. I can provide photos of the HIU and wall controller, as well as the previous engineer's report.

Dissassemble and descale/clean the thermostatic valve in my shower

£80

Highgate, Greater London

1st Sep 2026

My bath/shower’s hot water has become unreliable, although the hot water supply itself is working well. I think the problem may be limescale affecting the thermostatic mixer cartridge, so I would like it to be removed, inspected and cleaned. I started trying to do this myself but realised I don’t have the experience or tools for the job, so I’m looking for someone to help. The mixer is an Ideal Standard A4054AA Active bath shower mixer, and the thermostatic cartridge is S960134NU, in case that’s helpful. This is a slightly fiddly job that will require experience with thermostatic mixers and a toolkit. I particularly struggled to remove the plastic pin holding the cartridge/unit together, so I’d like someone who is comfortable dismantling and reassembling this type of mixer.

On time, friendly, and took the time to sort out a fiddly problem with our shower. Highly recommended!
