According to new research by Hillarys, the city ranks tenth in the UK for average annual heating costs, with households paying £1,055 per year to keep warm.
More than half (59.2 per cent) of homes in Salisbury are rated EPC D or lower, meaning they are likely less energy-efficient and more costly to heat.
Lisa Cooper, head of product at Hillarys, said: “If you don’t have a smart meter, make sure to submit a reading before or on Thursday, the 1st of January, to ensure your bill accurately reflects your energy usage at the old rate.
“The majority of suppliers have a dedicated app or web form where you can submit readings, but be sure to give yourself plenty of time to familiarise yourself with the exact process for your supplier ahead of the new year.
“This will prevent your supplier from estimating your usage at the new, higher rate and stop you from being potentially overcharged.
“While there’s no specific, universal amount you’ll save from this step, as it depends entirely on your personal usage, avoiding a potentially inflated bill can save your household anywhere from a few pounds to hundreds of pounds.”
The research highlights a national problem, as more than two million UK households plan not to use their heating at all this winter due to rising energy costs.
To help offset high bills, Ms Cooper suggests energy-saving measures such as bleeding radiators, using thermal blinds and applying draught excluders.
She said: “Draught excluders are a great option, which are long, filled fabric tubes placed at the bottom of doors to prevent cold air from chilling the home.
“It’s estimated that draught-proofing windows and doors can save you up to £35 per year.”
