Consumer firm Which? has weighed in its top energy companies for 2025, and you could save hundreds of pounds if you pick the right one.
Household energy bills surged by 1.2% this month after regulator Ofgem’s new price cap came into effect on January 1.
It means that the typical energy bill for homes in England, Scotland and Wales has now gone up from £1,717 a year to £1,738 – around £1.75 extra per month.
This comes after an earlier 10% hike in October last year. The price cap – the maximum amount a supplier permitted to charge – is also expected to go up yet again in April.
But according to Which?, going with the right provider might save a household £100-£200 a year.
The brand says that as many fixed deals from different providers offer very similar rates, “choosing a firm based on its customer service record, or switching away from one that’s frustrating you, might be more appealing”.
The best ones are, according to Which?, are:
- Octopus Energy
- Utility Warehouse
- 100Green
Which? surveyed 11,984 energy customers in September-October 2024 and asked them to rate six areas of service, how satisfied they are with their supplier and how likely they are to recommend it.
The consumer brand also assessed 18 energy firms’ practices and policies based on information they asked from them and alongside their own research.
The firms which ranked in the top 3 achieved a customer score of 70%, with at least three stars out of a possible five in each survey. Talso had to be score above average in a behind-the-scenes assessment of 17 criteria.
The included ease of contacting, handling complaints, support for those who need it, performance against smart meeting targets and how they handle the switching process. Meanwhile, Ovo Energy, So Energy and British Gas raked in the lowest scores.
Which? says it could be worth looking around for better deals if you are unhappy with your current provider. It points out that there are various tariffs on the market with rates cheaper than the current energy price cap.
According to MoneySavingExpert (MSE) founder Martin Lewis, households that switch will pay around 7% less for their energy compared to those on Price Capped tariffs and moving to a cheaper rate can prevent any future price hikes.
He wrote in his latest newsletter: “Most homes are on an Energy Price Capped tariff. The Cap went UP 10% on 1 Oct, UP another 1% on 1 Jan and it’s now predicted to go UP 3% to 5% on 1 Apr. Yet act NOW & you save now, and can prevent future hikes.
“The Price Cap isn’t a total cap on what you pay, it’s a limit on the daily charge & unit cost of energy, so use more, pay more. Most firms charge at the limit, and these limits are high now, meaning the Price Cap is a pants cap, as most can easily compare & switch to a cheaper deal.
“Move to the cheapest fix and within five working days you’ll be paying typically 7% less than what those on Price Capped tariffs pay. Plus, the rate is locked in so you get peace of mind that it won’t change, whereas the Price Cap’s predicted to rise further.”
