EDF's IOG-clone tariff
I've been on IOG for years but was tempted by EDF's very similar tariff, which is also driven by Octopus's Kraken infrastructure. I switched this week and thought some information might be useful for some people.
I had never been particularly tempted by the Eon version as I couldn't find any convincing evidence that their API would play nicely with Home Assistant, which is a must-have for me as I also have a house battery and solar. I took the plunge with EDF only after u/stek2022 reported about his fork of the BottlecapDave integration for EDF; there's a new subreddit for that integration here: r/HomeAssistantEDF Anyone who does decide to switch and for whom HA is useful might consider using his r e f e r r a l code, as I did (available on the github page.) He's earned it!
For me the switch was painless. I applied (by phone) on Tuesday; the switch occurred at midnight Wednesday night/Thursday morning; the selected tariff (GoElectric) and smart add-on (Smart Charge) activated on Saturday morning. Export will take a little longer but I was assured export payments will be backdated to the switch date.
Pros:
- Off peak import 6.99p 2300-0600
- Off peak also applies during smart charging periods for the whole house, just like IOG
- Rate fixed for one year
- £50 switch bonus until 24 May 2026, plus the usual £50 r e f e r r a l bonus
- £5 per month bill credit just for signing up to the intelligent functionality
- Fixed export 15p - also fixed for one year
- Works virtually identically to IOG (same setting of target times and targets, etc)
- Really easy to switch HA automations just by replacing Octopus entities with equivalent EDF entities
Cons:
- If you're in a PowerUp area for Octopus, you will no longer get these
- EDF is obviously a much smaller player in this space so it may be more difficult to get support from either EDF or a large pool of other users (like this sub!)
- So far, that's it
Worth a look, I would say. For me the clincher was the 12 month fix, given what the predictions for price increases look like this summer. I am in no way anti-Octopus and wouldn't be at all surprised if I end up back with them at some point in the future, but this made a lot of sense for me right now.
