Thermostat Installation and Heating Controls in Surrey
A faulty thermostat or unreliable timer can leave the heating off when you need it, or running when the house is already warm. Surrey Handyman installs and replaces heating controls across Surrey. We check the existing system, identify suitable replacement controls and test their operation, so you can set the heating times and temperature without struggling with an old or faulty unit.
Book Surrey Handyman for Thermostat Installation
Tell us whether the controls have developed a fault or you would like them replaced with something easier to use. Photos of the thermostat and programmer, together with the boiler make and model, help us prepare. If you have already chosen a replacement, send its details before buying it so compatibility can be checked.
How Long Does Thermostat Installation Take?
Replacing a compatible control is usually less involved than changing the wiring or adding a different control arrangement. The visit includes checking the existing installation, fitting the replacement and testing how the heating responds. Fault finding, additional wiring or changes to more than one control will take longer.
We will explain the likely time once we know what is fitted and what you want changed. Where a fault needs investigating first, the repair and any parts required will be discussed after the cause has been identified.

What to Expect When We Install or Replace Heating Controls
A new thermostat needs to work with the boiler and any existing heating or hot-water controls. We check that arrangement before fitting, then test the replacement and explain how to use it.
We check the existing controls
We identify the thermostat, timer or programmer and establish how it controls the heating. For a fault, we check the reported behaviour before deciding whether a replacement is needed. A heating problem is not always caused by the control itself.
The replacement is checked for suitability
We confirm that the proposed control is compatible with the boiler and the functions it needs to operate. Systems with stored hot water or more than one heating zone may need a different arrangement from a straightforward combi boiler installation.
The installation is made safe
The relevant electrical supply is isolated before wiring work begins. Existing connections and the mounting position are checked, and the old control is removed where it is being replaced. Any additional work identified is explained before proceeding.
The new control is fitted
The replacement thermostat, programmer or other agreed control is installed and connected in accordance with its instructions. Where the system uses a separate receiver or controller, these components must also be correctly connected and configured.
The heating response is tested
We check that the heating responds to the new control and that the relevant settings operate as intended. Where the work includes hot-water control or separate zones, those functions are checked as part of the installation.
We explain the settings
We show you how to change the temperature, use the timer and make ordinary adjustments on the fitted control. The instructions are useful to keep, particularly if its programmes or operating modes differ from the unit it replaced.
Other Heating Work We Can Complete
Problems with controls can become apparent alongside cold radiators, faulty valves or a boiler issue. Our team can look at the related work and arrange the appropriate heating engineer.
We can also help with:
- Repairing radiators that do not heat properly
- Replacing faulty radiator valves
- Fitting replacement radiators
- Boiler repairs and servicing
- Power flushing where system cleaning is needed
- Other central heating repairs and adjustments
Mention any other heating symptoms when booking, including whether your hot water is affected. That helps us allow time for the work instead of treating the thermostat as the only possible cause.
Customer Testimonals
Very helpful and prompt customer service. The 'handymen' Daniel and Ben were delightful and very efficient. We will certainly use them again. Colin sorted out the boiler once again. Very grateful.
A real pleasure to do business with them. Thoroughly recommend.

Praise for Surrey Handyman
We can’t praise Colin Stallman of Surrey Handyman highly enough. He came to us to fit a new gas boiler - our previous one being unexpectedly condemned! His knowledge and expertise was only topped by his hard work and professional manner and understanding of our confusing plumbing.
Lynne - Feb 2026
Colin was very polite and experienced. He completed the radiator work within the expected timeframe and left the room neat and tidy. I would highly recommend

Thermostat Installation and Heating Controls FAQs
Often, yes. The replacement must be compatible with the existing boiler and controls. We check the system before recommending or fitting a new unit.
Yes, provided it is suitable for the installation. Send the exact make and model before purchasing or booking. Some controls need additional components or wiring that must be allowed for.
A smart control may be an option, depending on the system. Tell us the model you are considering so we can confirm compatibility and whether we can carry out that installation. We do not assume every brand suits every boiler.
A room thermostat controls heating in response to the room temperature. A programmer sets the times it runs. Some controls combine both functions, while other systems use separate units.
Only if the thermostat is the cause. The problem could be in another control, the wiring or the heating system. We investigate the fault before recommending replacement parts.
We install and replace heating controls, including programmers. Tell us whether it controls heating only or heating and stored hot water, so the correct replacement and functions can be checked.
Often, yes. Wireless communication does not mean every component is battery powered or free of wiring. A receiver or controller may still need connecting to the heating system, followed by setup and testing.
Suitable controls can help avoid heating rooms when it is not needed. The effect depends on the existing system and how you use the settings, so there is no fixed saving for every installation.
Yes. We explain the main temperature and timing settings and check that you understand the normal controls before the job is finished.
