petrolprices.com is still going strong. nice to meet one of the OGs.

shell's logo does have a lot of yellow but morrisons has already claimed yellow on the chart.

data goes back to january but coverage is patchy early on as we were doing full fetches rather than continuous polling. march onwards is complete.

Ahhh thanks for that. I have deployed a change to fix this ASAP.

Absolutely, feel free to reach out. contact details are on the site. would love to see how I can help!

bespoke design but used tailwind for styling. charts are recharts. no dashboard lib.

really appreciate the feedback, that's a valid point. I will review and make it more accessible.

really appreciate you taking the time to check it properly. I will get them both fixed some time this week!

that 5 minute reporting requirement is way stricter than the uk.

Might have a play with that thank you.

yeah that's as far back as my data goes, started ingesting in march. no history existed before that

I would love too. But I have not found an API that surfaces this data. This data is only public as the CMA determined the market was fundamentally broken.

some of my replies yeah, been a bit busy keeping the site up while the thread was live. helps with the typos too.

Yeah aware of some data quality issues in the feed, bad coordinates, missing brands, occasional obviously wrong prices. I filter out anything outside 100-300p and exclude stations flagged as closed but there's definitely still noise in there. check the methodology page for the full detail on how i clean it.

On the colours, esso and shell are both red brands so they ended up close on the chart. will fix that.

checked the db, tesco e5 is 163.8p average across 292 stations in the last 21 days. Worth spot checking a few specific stations if it still looks off to you.
