Hi everyone, just got an ASHP and wondering what tariff everyone is on?

I've seen GoodEnergy have announced one but can't find any actual details, but Octopus Agile looks like it might be best.

Thanks

    There is no 'one size fits all' answer as it depends on your consumption pattern throughout the year; there are also regional variations in electricity tariffs.

    I doubt that Agile would suit you. A heatpump really has to be running for most of the time so IMO the cheapest single rate tariff would be most appropriate.
    As Cardew says, you ideally need to work out you daily consumption profile but in general you'd be using most energy during the day and evening and not a lot during the night.

    You'll need to learn how to use it properly to get the best out of it both in performance and energy consumption Dont try running it like a conventional boiler.
    I'd suggest that you read you leccy meter just before you go to bed and when you get up in the morning for the next couple of weeks to see what your day/night split is.

    I've had an ASHP for over 10 years and most nights (ie the off peak periods) it isn't running but it runs all day so there's no advantage for me in an off-peak tariff but there is in getting a cheap one. I presently get through around 7000kwh for all my leccy (heating, hot water, cooking washing etc) so just 1p a kwh is worth £70 a year on my bill.

    You'll find that your leccy consumption will vary wildly at this time of the year - heatpumps are less efficient when it very cold and less efficient when they are being run at high temperatures so they work better when they are running longer at lower temperatures.
