From 1st January 2026, the energy price cap is set to rise from £1,755 to £1,758 per year for a typical household paying by direct debit. Before this comes into effect, Go.Compare is encouraging households to take a meter reading, even if they have a smart meter, to make sure they are billed accurately.*

A recent survey also revealed that one in six (16%) of British bill payers say they can’t afford any more price increases on their energy bills, and a further 29% say they are worried about the cost of their energy bills.

Gareth Kloet, energy expert at Go.Compare explains: “As we move towards the new year, it’s really important for bill payers to log a meter reading as close to the end of December as possible. Doing this helps make sure the energy you’ve used in 2025 is charged under the outgoing rates, rather than being rolled over into the higher January cap.”

While the latest price cap was only a rise of 0.2%, Gareth notes that winter usage naturally climbs as homes rely more heavily on heating and lighting – so every penny counts. He said, “Even slight shifts in prices can feel significant when consumption is at its peak, so submitting an accurate reading before midnight on 31 December helps protect you from being overcharged – especially if your account relies on estimated readings. Smart meters don’t always communicate in real time, so taking a snapshot of your readings and sending these to your supplier gives you peace of mind.”

It’s also a good time, if you haven’t already, to reassess your tariff. And with 12% of those in charge of their energy supplier saying they are nervous about switching, Gareth explains what it means and how to go about it:

“With the cap adjusting in January, it’s worth reviewing whether your current deal is still right for you. If you’re on a variable tariff, now could be a good time to compare fixed-rate options.

“The important thing to remember is that every household’s usage profile is different, so what works for one home may not suit another. Take a look at your current energy contract – the standing charges, unit rates and any early-exit fees. Then take this information and shop around for a deal that works for you and your energy needs, using a comparison website.

“As always, if you’re finding it difficult to manage your energy bills, get in touch with your supplier sooner rather than later. Providers are required to support customers in financial difficulty and can help you set up a payment plan.”
