The UK is currently behind on the decarbonisation of home heating. In this report, we put forward a series of recommendations that, if implemented, will reduce emissions, bills, and government expenditure in the face of an energy crisis. We also show how a strong commitment to the electrification of home heating – and, as temperatures increase, cooling – is needed from the government now to create confidence and unlock investment across the energy sector.

While energy costs are finally falling, bills this winter will still be 78% higher than the pre-crisis average. The government should take ambitious steps to deliver affordable change in both the near and long-term, in a way that avoids the huge sums of money spent on temporary solutions. This report presents 6 recommendations to bring down bills, reduce emissions, and protect the fuel poor, ultimately calling for the delivery of a Social Tariff.

I welcome this UCL/Aldersgate Group report. The need for Government support for customers struggling to pay their energy bills is timely. It also serves as an important reminder of how smart, time of use tariffs can help all customers in keeping their costs down while supporting a decarbonising energy system. We fully support the recommendation of taking policy costs off electricity bills in order to encourage more customers to switch from gas to more efficient, green, electric heating.

A social tariff is essential to give millions of people certainty about what they’ll pay and protect them from excessive bills in this era of high energy costs. Time is running out for the government to follow through on its promise to introduce better targeted support by April 2024. Without urgent action we’ll see a repeat of the same crisis as last year - people unable to keep their homes warm, unable to keep the lights on and making the choice between heating or eating.

Aldersgate’s report rightly highlights the need to do more to protect those who are hardest hit by high energy prices. Well targeted support in the form of a social tariff which sets costs lower than the price cap for specific groups would be a progressive way to provide support to those who need it the most. We also know that installing heat pumps into homes is key to reducing our dependence on fossil fuels and cutting carbon emissions. Moving levies from electricity bills is a key policy needed to push down the cost of running a heat pump, which would accelerate uptake and increase the affordability of electric heating.
