Electricity prices for UK manufacturers are roughly 80% higher than the EU average, according to recent government data. That gap is squeezing factories, foundries, and food processors. This week, Ecotricity and Make UK published a report on how to cut those costs, as reported by Ecotricity. But here’s the question Axiom Eco Homes hears from readers every week: what about our homes?
Why the gap matters for households
The report’s recommendations, on-site solar, battery storage, heat recovery, and smart load shifting, are not factory-exclusive. A typical 3-bed semi could cut its electricity bill by 25–35% with a 4 kW solar array and a 5 kWh battery, according to Energy Saving Trust estimates. Yet the upfront cost, around £7,000–£9,000 installed, remains the barrier. Manufacturers can access capital allowances and industrial decarbonisation grants. Homeowners get the Boiler Upgrade Scheme: £7,500 off a heat pump, but nothing for solar or batteries. The inequality is stark.
What the report gets right, and misses
The report pushes for time-of-use tariffs and on-site generation. That is exactly what Octopus Energy’s Agile tariff offers households: prices that fall to near zero at midday on sunny Sundays. But the catch is that only 2% of UK homes have smart meters set up for half-hourly settlement, according to Ofgem’s latest data. The report does not address the complexity of retrofitting older UK housing stock, 60% of homes built before 1980 have cavity walls that are either unfilled or poorly insulated. A factory can install a heat recovery system in a week. A Victorian terrace needs a year of work and £15,000–£25,000.
What UK homeowners can do now
Three steps mirror the report’s logic but fit a household budget. First, check if you are on the cheapest tariff, 11 million households are still on standard variable rates, paying roughly £100–£150 more a year than the cheapest fix, per Ofgem. Second, apply for the Great British Insulation Scheme if your home has an EPC rating of D or below; it covers loft and cavity wall insulation at reduced cost or free for low-income households. Third, consider a smart meter and a time-of-use tariff, even without solar, shifting your washing machine to 2pm on a windy day saves about £80 a year. The government’s next move should be to extend the Boiler Upgrade Scheme to cover solar PV and battery storage. Until then, homeowners are left to copy the manufacturers’ playbook, but with their own money.
Frequently Asked Questions
Not directly. The Boiler Upgrade Scheme covers heat pumps, not solar. The Smart Export Guarantee pays for excess electricity exported, but at low rates (typically 5–15p/kWh). Some local authorities offer solar loans, but availability varies.
Yes, if you can shift high-usage appliances to off-peak hours. Octopus Agile and EDF's Tracker tariffs can save £50–£150 a year for a typical household, but require smart meter data and some planning. Check your current tariff's standing charge and exit fees first.
