Additional Smart Thermostat Installation Costs

With a new smart thermostat in your house, you might want to upgrade more of your property to include smart home functionalities. Here's what you can consider:

Installing a New Smart Meter Cost

smart meter costs

A smart meter is a natural pairing with your new smart thermostat. Smart meter installations cost between £30 and £70, and once they're in, you'll benefit from accurate billing as you pay for what you use instead of estimated values and real-time energy usage so you can track your consumption.

electric meter costs

If you're having a new smart meter installed, you'll need a budget for the cost to remove your existing electric or gas meters. This ranges anywhere from £400 to £1,000, and can only be completed by a professional due to the complexity of the work.

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 between £50 to £100 for a smart bulb, with a smart hub costing £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 are a few things to consider with smart thermostats. You must consider that they are different to smart meters. 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 paying to install the meter.

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."

You should also consider that there is a difference between smart meters and smart thermostats. Smart meters will tell you information on your gas and electric meter readings, while smart thermostats will allow you to control your heating from your phone, even when you are out of the house.
