What tariff do you recommend?

We recommend a time-of-use tariff, with 1 or more off-peak periods. Octopus, OVO, EDF, Scottish Power and others offer these, often marketed for EV drivers. Alternatively dynamic tariffs will also make full use of the ZEB’s flexible storage and let you take advantage of surplus renewable generation and (potentially) negative pricing. Which one will be the cheapest for you will depend on your other consumption needs.

You should also explore what the best boiler settings are for you to save money. We have resources available for helping you optimise your habits and heating system to make the most of your ZEB.
