Octopus Cosy London

Tips for Saving on Your Electricity in London


Run Appliances During Minor Cosy Price Dips

Use small reductions in the tariff to operate high-energy devices like washing machines and dishwashers.

Rely on Heat Pump Weather Compensation

Allow your heat pump to automatically adjust based on outdoor conditions for maximum efficiency.

Use Price Dips for Hot Water Heating

Schedule hot water heating during minor tariff dips to save a little each month.

Enhance Insulation

Better insulation reduces the energy required for heating, letting your heat pump run efficiently.

Try a Smart Remote Heat Pump Controller

Controllers like Havenwise automate heat pump usage according to time-of-use peaks and troughs.
