It’s time to leave gas behind
Bills keep climbing
Gas prices spike, but they never really fall. Every year, you pay more for the same heat.
Gas is a gamble
Sticking with gas ties you to imports and global shocks you can’t control.
Old tech, old problems
Boilers waste energy, break down, and keep costing you money.
Warm home, happy planet
Heat your home in comfort while cutting your carbon footprint.

Survey & Plan
We confirm your home’s suitability and finalise your quote. Quick, simple and at your convenience.
Install & Switch-On
We fit your cylinder-free heat pump and get you heating/hot water the same day with minimal disruption, then we add the battery and smart controller and then commission the full system.
Optimise & Care 24/7
Your smart controller automatically charges the battery and runs the heat pump when electricity is cheaper, then uses that stored energy to keep you warm when you need it.
