It depends what plan you're on at the moment. You can't switch between the winter and summer plan whenever you want, but all the others say:
If the ...Plan does not fit your lifestyle, you can switch to another Plan at any time.
Also look at what capacity (power rating) you're on. If you're on 5.75 kW, it might be feasible to reduce costs by switching to a lower capacity.
Iberdrola have a power calculator to try and help you decide what power
rating you need:

Mind you, it's not that clever, and tends to over-estimate what you need.
In my opinion, it's best to consider the maximum number of appliances you're
likely to have on at any time, and work out what power that will consume. We're
in a three bedroom house with two electric ovens and hob, three aircons,
washer, dishwasher, dryer, deep-fat fryer, kettle etc. We're on the 5.75 kW
capacity and have only once tripped the smart meter.
