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 Shower Thermostat

Hampstead, Greater London, NW3

Need to replace shower thermostat which is broken and now only works on very hot setting - replace part with correct specifications already bought

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!

Unscrewing a shower attachment to allow removal of thermostat

£80

Kentish Town, Greater London, NW5

26th Aug 2026

The thermostatic valve on a shower needs cleaning or possibly replacing. It was installed to make servicing impossible. The valve 52mm nut cannot be accessed. The water supply to the shower is off. So, the shower unit needs to be unscrewed from inlet hot and cold supplies and outlets in order to access the valve. This is visit one. Then I will sort out the thermostatic valve. Once that is done - visit two, maybe a week or so later, will be reassembly and checking everything works with no leaks! The suggested price is one visit

Just excellent. Thank you Stuart

Replace Thermostats on Electric Radiators

£100

Clapham Park, Greater London

8th Aug 2026

I have 4 electric radiators in my flat with manual dial-style thermostats (pictures attached) I want the thermostats on all 4 radiators replaced with smart thermostats, which will be linked to my smartphone. I want to be able to set the temperature and timers for all 4 radiators centrally from my phone. I am happy to purchase the materials myself if you can recommend to me which thermostats to buy. In addition there is an issue with one of the radiators where it makes a noise and does not heat up properly when turned on. I need this to be investigated and repaired if possible.

Great experience with Juan and his team

Replace concealed thermostatic shower valve

£120

Dalston, Greater London, E8

6th Aug 2026

Hello, I need a quick quote to replace an existing concealed thermostatic shower valve in my bathroom in E8. I have already purchased the replacement part. It is a direct like-for-like generic swap: removing an ENKI Dulwich TSV021 and putting in a Trisen Formby TSV102. Both units share identical 135–165mm pipe centres. It is a straight swap through the existing wall plate hole so a fixed price for an hour of time to do this.

My concealed shower tap's thermostatic cartridge needs cleaning or replacing. Water is hard to mix, always too hot or too cold! Obviously if it needs replacing i would need to buy it and you'd have to come back and I'd pay for both times... I tried to take it out to get a picture but I wasn't able to get the tap cap off,even after taking out the screws.

Help cleaning/changing a thermostatic cartridge (shower mixer tap).

Stepney, Greater London, E1

30th Apr 2026

My shower keeps switching between scalding hot and freezing cold… done a bit of research online, looks like it’s an issue with the Thermostatic Cartridge. Need to remove the cartridge and assess the situation, it might just need a descale. Just not really sure how. I’m guessing it’s not a huge job. If time and skills permit I’d also like to hand a couple of hooks on the wall, just not confident with a drill. Thanks.
