Additional Smart Thermostat Installation Costs
When installing a smart thermostat, you may consider upgrading other parts of your heating or electrical system.
Here's what you can consider:
Smart Meter Installation
A smart meter measures your gas and electricity usage and automatically sends readings to your supplier.
Many UK energy suppliers install smart meters at no upfront cost. If you want a full breakdown of potential charges and eligibility, see our guide to smart meter installation costs.
In most cases, suppliers manage standard meter upgrades. However, if relocation or specialist work is required, moving a gas or electric meters costs average around £1,000 (depending on complexity).
Installing Smart Lighting Cost
For ultimate ease of use, you can install smart lighting throughout your home so you never need to touch a light switch again.
Smart lighting costs around £85 to install. A smart hub costs between £60 to £150, depending on the make and model.
If you want smart lighting throughout your entire home, you can expect costs between £3,200 to £10,500.
Things to Consider When Installing a Smart Thermostat
There is a difference between smart meters and smart thermostats:
- Smart meters will tell you information on your gas and electric meter readings, sharing that with your energy supplier.
- Smart thermostats allow you to remotely control your heating from your phone, even when you're not home.
Many energy companies will install your smart meter for free, but with smart thermostats, you will have to pay for the thermostat, as well as pay to install the thermostat.
Installation prices will vary depending on the type of smart thermostat you buy, and the labourer's daily rate.
How can a smart meter improve the energy efficiency of my household?
"It's all about using your services and device in a better and more effective way. The smart meter displays your usage, helping you remember to turn off lights and avoid standby mode when you're not around. This way, you stay in control and are more informed, allowing you to act more efficiently."
Smart Thermostat Installation (DIY)
While it's possible to install a smart thermostat yourself, it can be a complicated job, which is why it’s always easier to hire a professional to install it for you.
To do so, you'll need to remove your existing thermostat and label the wires so you know where they connect to the new one. This could get complicated if you've never dealt with electrics before.
Here's what we suggest if you want to install a smart thermostat yourself:
- Look online for a step-by-step installation video from your smart thermostat manufacturer.
- Ensure you've got the right tools to hand before starting (screwdriver, spirit level, drill).
- Make sure you label the wires clearly before disconnecting them so you know what they are.
I had a smart meter fitted, and now my shower only has hot water for 10 mins. Can this be related to my fusebox?
"It shouldn’t really affect your hot water at all. There might be some wiring that needs changing or checking. I would advise you to have your boiler checked over."
You will need to use a drill if you're planning on installing your thermostat yourself. This could cause serious damage to the wall if you make a mistake.
Whilst you could do it yourself, it’s not an easy job if you haven’t had experience installing a smart thermostat. To save money and time, you should hire a professional to install your thermostat without stress.
Can I install a smart thermostat myself, or must a professional do this?
"I personally think that an electrician should have a look at this for you."
Checklist: Hiring a Smart Thermostat Installer Near You
Here's what we suggest when you're looking for a smart thermostat installer:
- Gather at least 3 quotes from local smart thermostat installers to compare your costs.
- Ensure quotes are itemised so you can see exactly what's included in your quote, leaving no room for hidden fees.
- If you're moving your existing thermostat or meter, ensure you hire licensed professionals to deal with electrics and gas, with NICEIC-approved electricians and Gas Safe Registered engineers for both jobs.
- Take a look at the thermostat installer's customer reviews, taking note of any unhappy customers as these could be red flags for you.
- Be sure to check the installer is comfortable with your exact smart thermostat and has experience in fitting and installing them.

FAQs
Will a smart thermostat work with my existing boiler?
Most smart thermostats will work with existing boilers, including combi and system boilers. Older boiler systems may need an additional receiver or wiring adjustments to work with a smart thermostat. This is something you should ask about when getting quotes from local smart thermostat installers.
How much can I save using a smart thermostat?
UK government-backed research has found that households with a smart thermostat used around 5% less gas than households that were using standard thermostats.
This was confirmed as a statistically significant effect, but the real impact on your bills could be anywhere between around 1% and 9% depending on how you use it.

Does a smart thermostat need WiFi to work?
You'll need WiFi to operate your smart thermostat for features like scheduling or controlling heating automation from your phone or another smart device, such as Alexa.
But, if your internet connection goes down, the thermostat will still operate with basic functionalities. However, you just won't be able to change the settings from your devices until you resolve the issue.
