The price cap will rise by £63 in October, the third increase this year. That brings the typical household bill to £1,928 a year, according to Ofgem. Unite, one of Britain’s largest trade unions, has responded by planning a day of action against what it calls ‘energy price hikes that are crushing working people.’ The protest, as reported by the Morning Star, targets the government’s failure to intervene in a market that has delivered record profits to suppliers while millions struggle to heat their homes.
What the price cap actually does, and doesn’t do
The price cap, introduced in 2019, was meant to protect households from profiteering. But it doesn’t cap your total bill. It caps the standing charge and the unit price per kWh. So when wholesale gas prices rise, as they have since the invasion of Ukraine, your bill rises with them. The typical household using 12,000 kWh of gas and 2,900 kWh of electricity now pays 24.5p per kWh for electricity and 6.24p for gas. That is 12% higher than a year ago. The cap doesn’t stop the pain; it only limits how fast the knife turns.
The catch is that the price cap is a political choice. The government could mandate a social tariff, a lower rate for low-income households, as Citizens Advice has urged for two years. It could reintroduce the Energy Price Guarantee, which capped bills at £2,500 in 2022. It could tax excess profits and use the revenue to cut bills. Unite’s demand is that the government do all three. But so far, the Treasury has refused, arguing that market intervention distorts signals.
What this means for your home and your wallet
For the typical 3-bed semi in the UK, the October rise adds £5.25 a month. That doesn’t sound catastrophic, but stacked on two previous rises this year, £28 in January and £17 in April, it means an extra £50 a year compared to last winter. For a household on a prepayment meter, which already pays more, the total could exceed £2,200. The Energy Saving Trust estimates that 6.5 million UK households are in fuel poverty, meaning they spend more than 10% of their income on energy. Every rise pushes more families over that line.
But there is a personal response that the state cannot deliver: efficiency. A home with cavity wall insulation, loft insulation to 270mm, and a modern condensing boiler uses about 30% less gas than an uninsulated one. Add a heat pump and solar panels, and the saving can exceed 50%. The Boiler Upgrade Scheme offers £7,500 off a heat pump. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. These upgrades don’t just reduce bills, they raise your EPC rating, which adds value when you sell.
Political protest and personal action, two sides of the same coin
Unite’s day of action is about collective pressure. But the government has shown it responds slowly to protest. The real shift happens when enough homeowners demand change through their choices, and their votes. Installing solar panels cuts your electricity bill by 40-60%, depending on orientation. A 4kW system costs about £6,000 and pays back in 8-12 years. With a battery, you can store cheap daytime generation for evening use, avoiding peak rates. The economics improve every year as grid prices rise.
Yet the government’s own data shows that only 1.3 million UK homes have solar panels, about 4% of the total. The potential is huge: the Climate Change Committee says 40 million homes need heat pumps by 2050. We are installing about 50,000 a year. At that rate, it will take 800 years. Unite’s protest is one way to force faster policy change. The other is to make your own home a demonstration project, lower bills, higher comfort, less carbon.
What you can do now
Check your EPC rating. If it is D or below, you are losing heat through walls, roof, or windows. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. Get a quote for a heat pump through the Boiler Upgrade Scheme. Compare solar installers on the MCS website. And write to your MP asking them to support a social tariff and a windfall tax on energy profits. The price cap is a political choice. So is the roof over your head. Both can change.
Frequently Asked Questions
Directly, no. A protest does not change the price cap overnight. But it builds political pressure for a social tariff or windfall tax, which could cut bills for millions. In the meantime, efficiency upgrades are the only guaranteed way to reduce your own bill.
Switch to a fixed tariff if you are on a standard variable rate, some are now cheaper than the cap. Then insulate your loft and draught-proof windows. Both can be done in a weekend and save £100-200 a year.
