@toodles Great that Cosy is working out for you. I've not tried the Octopus Compare app, but without the benefit of batteries I find it non-trivial ...
British Gas are also offering at 14p/kWh tariff for the first year for heat pump usage: Presumably they have a separate billing meter for the ASH...
We have just had our property updated on the ECO4 scheme, so I will share our experience here for others. Firstly, there are literally dozens of com...
@toodles In your situation, with batteries, I agree that you have made the right decision - being able to lock in half price electricity at 11p in the...

@mike-h Yes, I was aware it's not ideal, as discussed in this article: The installers insist on a volumiser (a) to ensure the minimum volume is a...
Yes, it really is a volumiser (2 pipe tank), and it is located on the primary 28mm return to the ASHP as shown here: so is on the return for both ...
Agreed, even a 5kW battery would allow one to charge at 11p and avoid importing at 34p during the peak period, plus it gives added comfort and conveni...
I am so relieved to find this thread and discover that I am not the only person obsessed with this - Like Steve, I have no issue with looking at the d...
Yes, we have a 50L volumiser installed, and our radiators can emit the minimum heat output at flow temps of 33-34C, so this is as low as we can go.
