Current single rate tariff 16.63 pence per kilowatt hour, compared to a neighbouring flat paying 9.93 pence per kilowatt hour on an E7 tariff for space and water heating.
Her flat has two HHR storage heaters that take a 24 kilowatt hour charge each plus a hot water cylinder with an immersion heater.
This has to be balanced against the peak rate being 19.08 per kilowatt hour peak rate on the two rate supply.
That’s a screenshot of the tariff details of the Smart meter two rate supply in the photo, compared to the figures I quoted from another adjoining flat the day rate is less, but the night rate is higher.
Without annual consumption totals for each rate it’s not really possible to work out which is the best deal.
On the basis that the meter swap is free, so straight off that is a saving of £120 I am going to have to suggest she has a look at Boost who installed that Smart meter.
