Green Energy Surges as UK Fuel Prices Climb

UK households sharply increased interest in green home energy upgrades in March , as higher fuel costs following the Iran crisis pushed more consumers to look for alternatives to traditional energy use. Companies serving the residential market reported a rapid rise in demand for solar power systems and electric heat pumps compared with the prior month.

Octopus Energy said sales of solar power systems were up by almost 80% in March versus February. The company also reported that heat pump orders doubled over the same period, pointing to a broadening shift beyond rooftop solar into electrified home heating.

British Gas reported a similar pattern in customer interest, saying inquiries about solar panel installations rose by 250% since February 28. The increase in outreach suggests households are actively seeking information and quotes, not only making purchases, as they respond to changing energy price expectations.

The surge in demand for solar panels, electric vehicles, and heat pumps has coincided with a projected rise in household energy costs. Energy bills are expected to increase by 18% from July, with an average annual dual-fuel tariff forecast at £1,929, according to the figures cited in the source material.

One driver of the higher cost outlook has been the move in wholesale gas markets. The European benchmark gas price has risen by approximately 50%, adding pressure to retail energy pricing and reinforcing consumer concerns about exposure to global fossil fuel price swings.

Other firms operating in home energy upgrades also reported stronger demand. Furbnow, a provider of home energy improvements, said inquiries increased by 42% since late February, and it described a notable share of interest as focused on reducing dependence on fossil fuels.

Furbnow said nearly three-quarters of its new prospective customers requested solar panels, while over half expressed interest in electric heat pumps. Taken together with the figures from Octopus Energy and British Gas, the data points to a broad-based consumer response across multiple providers rather than a single-company effect.

Uncertainties remain around how long the demand spike will persist and how quickly installations can be delivered, as the source material does not provide details on capacity, lead times, or regional distribution. It is also unclear how much of the March increase reflects immediate purchasing versus longer-term planning prompted by the expected July bill rise.

Still, the reported jump in inquiries and orders highlights how geopolitical shocks and wholesale market moves can quickly translate into household decisions, with implications for UK energy retailers, installers, and the wider European gas market that influences pricing.
