Another deal is on Tado’s Wireless Smart Thermostat Starter Kit that is now £135.99, down from £239.99 (over 40% discount). Smart thermostats are a long-term solution to help people to save an average of 22% on annual energy costs. This saving could be a lifeline for those struggling to pay their bills and keep their home warm in 2022. The Wired Smart Thermostat Starter Kit is for homes with an existing wired thermostat, and the Wireless model is for homes with an existing wireless thermostat or for buyers who want to upgrade a wireless thermostat. This wireless model comes with a wireless receiver that wires straight into the boiler and will talk to wherever you place the Tado wireless thermostat. With the Tado app, you get full control over your heating from anywhere you have a wireless or mobile connection, so you can reduce your energy consumption and save money with its intelligent features and smart schedules. For more details read our Tado Smart Thermostat review. Smart Schedules allow you to set your desired temperature individually in each room, at any time. And it’s only active when someone is in the home. If no one is home or an open window has been detected, the app reminds you to turn down the heating via push notification.

Due to rising energy prices, the demand for energy efficiency has gone through the uninsulated roof, with sales climbing fast in a growth market. Tado today announced that it has sold over 2 million smart thermostats across Europe. In the UK the Treasury has announced The Energy Bills Rebate, a £200 rebate on final energy bills in 2022, for all UK homes. This presents a significant opportunity for UK homeowners to invest in low-cost energy efficiency measures for their homes, to offset future energy costs.
