Amid the coughs, comedians and chaos of yesterday’s Conservative Party conference, Theresa May confirmed that the government is to publish a draft bill to cap prices on standard energy tariffs and end “rip-off energy prices”.

The prime minister had proposed, and subsequently shelved, plans for a price cap as part of her party’s general election manifesto earlier this year, but yet another change of plan has put energy price caps back in the news again.

Why do we need an energy price cap?

As things stand, energy suppliers set different rates for different tariffs designed to meet the different needs of consumers across the country. And while recent recommendations in the industry have led to the introduction of simpler and cheaper energy tariffs, it’s still the case consumers sat on standard variable rate plans pay more for their energy.

If you’ve let a fixed price plan lapse without switching to a better deal, or you’ve never switched at all, you’ll have been placed on your supplier’s standard variable rate tariff and will be paying more for your gas and electricity.

Although last year was a record year for switching – almost 5 million people switched energy supplier in 2016, up by a quarter (26%) on 2015 – there are still between 12 million and 15 million households on standard tariffs, all overpaying for energy to the tune of £1.4 billion a year, according to estimates from the Competition and Markets Authority (CMA).

How will an energy price cap work?

The details of exactly how the price cap will work are still unclear, but the government will be handing over more responsibility to Ofgem, the energy regulator, who will be given the power to impose a cap with no threat of appeal from the energy companies.

This won’t come as welcome news to suppliers, two of which saw their values drop by £1 billion yesterday, following the announcement.

The cap will be applied to supplier’s standard variable rate tariffs, and will most likely be based upon the system currently in place for the 4 million households using pre-payment meters. The level of this pre-payment cap is set by Ofgem every six months, and the regulator uses this power to control the maximum prices suppliers can charge for gas and electricity, based on its view of the costs that they are facing.

Will the price cap be good for consumers?

Opinion is pretty much split down the middle – while supporters of the price cap believe it will result in fairer energy prices for all consumers, its critics reckon it will kill competition, as similar caps in other countries have seen prices bunch around the level of the cap, meaning there is actually less value on offer to consumers.

And then there’s the risk that competition could be driven from the market completely, particularly if the bigger suppliers pull the best deals and completely force out the smaller providers who can no longer compete on price.

It could also signal bad news for business energy bills, as suppliers might push up the price of commercial contracts to claw back the money they lose as a result of the cap.

Getting the level of the cap right is the biggest challenge facing both the government and Ofgem – set it too high and the ‘rip-off’ energy prices remain, too low and there’ll be little or no reason to switch, which could all but kill the competition.

Is it time to renationalise energy supply?

Yesterday’s speech from Theresa May outlined how she and her party are very much in favour of free markets, but are not afraid to intervene in those that aren’t working as they should.

So the decision to get involved in energy pricing suggests that the government believes this is a market that’s not working in the best interests of its customers.

We took to Twitter to find out whether people think energy supply should be renationalised, as the Labour Party suggested during its general election campaign over the summer, and the results were conclusive (albeit from a small sample size).


But would renationalising energy supply really be a silver bullet for energy prices, or the final nail in the coffin for competition? Let us know your thoughts by leaving a comment on our Twitter or Facebook page.
