From Monday, the independent energy supplier First Utility will offer a free portable home-heating thermostat worth £279 to anyone signing up to its new three-year fixed tariff, iControl Fixed May 2018.

The company's research estimates that savings of as much as £165 are possible by using better heating controls. The Cosy smart thermostat offered through the deal was developed by the UK tech company Green Energy Options and includes a mobile app, so users can control their home heating from anywhere.

To get it, you'll need to fix your tariff for three years with the deal that is being launched on Monday. However, while fixing will ensure that you avoid any price increases for 36 months, you'll also miss out on any potential price cuts that may be in the offing.

Air tax jettisoned but refunds won't just fall from the sky

Air passenger duty for the under-12s is being abolished from next Friday, 1 May. The move will save a family of four with two kids under 12 £26 on a flight to Europe and £142 on a flight to the US, according to the Government.

However, the comparison site Money.co.uk warns that not all airlines are offering automatic refunds, with many asking consumers to apply to get their money back. To add further complexity, parents who booked package deals will have to go back to the tour operator to make a claim, not the airline.

It means anyone who has booked a flight for a child aged 2-11 for after 1 May must check whether they paid the duty. If so, they need to ensure they get the money back from either the airline or the travel agent.
