How WinterLock works

WinterLock fixes your electricity unit rate for the months when your business uses the most power.

Agree your rate: we agree a fixed electricity unit rate with you before winter.
Fixed all winter: that rate applies to every unit you use from now until March 31st 2027.
After winter: your electricity moves to market-based pricing or your standard contract rate.

A fixed winter rate doesn’t mean a fixed winter bill. If you use more electricity, your bill will still rise. WinterLock fixes the price, so you can focus on usage, scheduling and waste.

Why fix your winter rate?

Winter brings higher usage and less room for surprises.

Higher usage: darker evenings, heating and longer trading hours push consumption up.
Less predictable prices: wholesale markets, network charges and cold spells can all move costs.
Clearer budgets: a known unit rate makes forecasting and cashflow planning easier.
