As long as it’s actually cheap that’s not an issue. Swapping to a resistance heater when electricity rates cost less than natural gas is a cheap and straightforward way to suck up excess electricity in the winter. Unfortunately, UK fees may prevent ultra low retail rates even if wholesale power is cheap.
A more elaborate system can use predicted rates and thermal mass with heat pumps to dramatically reduce energy costs while also shifting demand to peak production periods.
