return to grid and energy
I thought this was not a thing? i.e. it was at 1 point but they stopped it?

At one point it was something insane like 50p per kWh.
It still exists but it's nowhere near that. Something like 7-12p per kWh.

Octopus has various electricity sale tariffs.
They still have a fixed export tariff which is quite generous at 15p /kWh sold.Also they have various smart tariffs which have a dynamic buy sell price, which can work out really well if you have a lot of battery storage.
Because of the 15p/kWh sale, it worked out cheaper to pay for gas and sell the spare electricity instead. Not the most environmentally friendly option, but better financially.

It’s is still a thing but they pay absolutely fuck all and shaft you.

I'm calculating around 8 years payback at the moment. It's tough because return to grid and energy tariffs are all over the place.
Costs are as follows:
Estimated annual electricity usage - 14,000kWh
Estimated usable generation - 4,500kWh
Estimated annual electricity saving with Solar / battery - £1.3k (ish)
Estimated annual gas saving with ASHP - £?? probably a slight increase but that's more about ditching gas than saving money
I'll need to see how to manage the ASHP practically with the cheaper overnight energy rates, battery storage etc to see if it can save money vs gas.
Currently looking like the solar install will be by Christmas but ASHP won't be until May.
