Good news! Gas prices are finally starting to rise. They were too low for a while, which made heat pumps less competitive. Fingers crossed that electricity prices will drop and more people will order heat pumps! 🎉 ⚡️🔥 @janrosenow.bsky.social @martinlewis.moneysavingexpert.com

What's a true "Zero Disrupt / Express" heat pump installation? A HYBRID install: boiler + heat pump. Minimal disruption, no performance worries, and 80% less gas. Add it to the scheme💙 @betatalk.bsky.social @janrosenow.bsky.social @chiefgeekad.bsky.social @octopus.energy @edfenergy.com
To make the switch to clean energy easier, we should aim for lower electricity prices, not higher ones. Lower electricity prices would encourage more people to use heat pumps 💚
