The UK energy market in 2023 explained

Energy customers in the UK saw dramatic increases in their energy bills thanks to wholesale energy becoming more expensive at the end of 2021 due to a range of factors such as high gas costs, low wind energy generation and a fire at the electricity interconnector between Britain and France. These high wholesale prices and increased general market volatility resulted in suppliers taking deals off price comparison websites like Uswitch. This is due to them trying to get to grips with the costs of supplying energy to you and wanting to adjust their tariff prices appropriately.

Additionally, August 2022 saw a new standard variable price cap level of £3,549 announced which was due to come into effect from 1 October 2022. However, under the Energy Price Guarantee scheme, this was reduced and frozen at £2,500 per year for average use dual fuel customers, meaning that the vast majority of customers were still paying expensive fees for their gas and electricity, but less than they otherwise would have been.

In March 2023, the government level will remain at £2,500 for three more months from April to the end of June.

Can I switch? Should I switch?

There are currently no fixed energy deals available, but this may change quickly - as wholesale prices come down, there is more incentive for suppliers to offer them. The best thing to do is sign up here to hear about energy deals as soon as they become available.

Is the government doing anything about high energy prices?

In addition to the Energy Price Guarantee, which was announced in October 2022, various relief measures were announced by the government to help customers with their energy bills.

The measures included a £400 discount on energy bills for all UK households (to be repaid across the next five years), various means-tested one-off payments and a £150 rebate on Council Tax for those in bands A-D. Eligibility for the Warm Home Discount was also be expanded and the payment level raised from £140 to £150.

For those without a traditional energy supply arrangement, there was a scheme called EBSS Alternative Funding. This totals £400 for those in England, Wales and Scotland who don't have a direct relationship with an energy supplier. Additionally, the Alternative Fuel Payment will pay £200 to households in England, Wales and Scotland which use alternative fuels (such as biomass or heating oil), Households in Northern Ireland will receive a £600 payment which combines the EBSS and the Alternative Fuel Payment.

How did we get here?

The energy market is rarely straightforward at the best of times, but the last few months of 2021 saw developments that have changed the way the market looks from a customer point of view.

From a customer point-of-view, the first sign that something was different about the energy market might have been in August 2021, when the level of the standard variable tariff energy price cap was raised to £1,277. 

Many customers looking to switch their energy deal in the wake of that news found that their potential annual savings were in the tens of pounds, rather than hundreds. In some cases, they might not have been able to save at all.

Wholesale energy price changes

Energy suppliers in the UK buy the energy they supply in bulk from the wholesale market. The price at which they buy the energy is the most significant driver of the amount they charge customers who sign up to their tariffs. The lower this is, the cheaper their tariffs will be - but the higher it is, the more expensive their tariffs will be. Unfortunately, this is the case at the moment.

Some of the reasons for this include:

• British and European gas storage levels are at a historically low level, compounded by protracted cold temperatures

• Low wind generation across Europe in 2021, which has increased demand from gas burning electricity-generating plants

• Increase in wholesale electricity prices caused by rising gas prices - if gas prices rise, the cost of producing electricity in these power stations rises and the cost of the electricity rises in turn.

Will prices drop?

The one constant thing about the energy market is its fluctuation. This remains true - while prices have decreased, they remain much higher than they were two years ago and it’s difficult for anyone to formulate a view on where prices will go long-term.

What happens if my energy supplier goes bust?

There's no need to panic if your energy supplier goes out of business as a result of these gas shortages and subsequent high prices. You'll be moved onto a Supplier of Last Resort by Ofgem - this could be any supplier that Ofgem deems a good choice to take on more customers. You won't lose your energy supply at any time. Your new deal may be more expensive than the one you were on, though, so you might want to see if anything else is available (though given the current situation, this might not be the case).

Which energy suppliers have gone bust as a result of the current situation?

As of March 2023, the following suppliers have gone bust largely due to the wholesale price rise situation:

• PfP (approx. 80,000 customers transferred to British Gas)

• Moneyplus Energy (approx. 9,000 customers transferred to British Gas)

• Utility Point (approx. 220,000 customers transferred to EDF Energy)

• People's Energy (approx. 350,000 domestic and 1,000 business customers transferred to British Gas)

• Green (approx. 255,000 customers transferred to Shell Energy)

• Avro Energy (approx. 580,000 customers transferred to Octopus)

• Symbio (approx. 48,000 customers transferred to E.ON Next)

• Igloo (approx. 179,000 customers transferred to E.ON Next)

• Enstroga (approx. 6,000 customers transferred to E.ON Next)

• Pure Planet (approx. 235,000 customers transferred to Shell Energy)

• Colorado Energy (approx. 15,000 transferred to Shell Energy)

• daligas (approx. 9,000 customers transferred to Shell Energy)

• Together Energy/Bristol Energy (approx. 176,000 customers transferred to British Gas)

• Bulb (1.6 million customers still with Bulb as it is being run by special administrators).

Are business energy customers affected by this situation?

Similarly to domestic customers, the business energy market is affected by high prices, but business customers looking to switch their energy are still free to run a comparison or talk to their supplier to see if they can negotiate a better contract than the one they're currently on.
