Energy Stats UK is my hobby website that I started in 2019.
It uses the Octopus Energy open API calls to summarise both historical and daily energy tariff data with graphs and stats.
You can see pricing data for many of the popular Octopus Energy import tariffs like Agile, Go, Intelligent Go, Cosy, Flux and Tracker.
As well as their export (outgoing) tariffs where you can get paid for your surplus Solar, Wind and Hydro power.
Just use the website menus to find the tariff / your region combo.
The site is also my place to blog about my renewable journey of Solar PV, Home Batteries, EV, Mixergy water cylinder, Plant Room and Vaillant Arotherm Plus heat pump.
As well articles about Heat Pump Tumble Dryers, What Size Heat Pump, FLIR Thermal Cameras and Low Temperature Heating.
These articles lead to an appearance on the BBC News website on their article: Heat pumps: The ‘geeks’ obsessing over their new heating systems.
As well as being a guest on two episodes of the Heatio Home Energy Show podcast.
You can find all my blog article posts here: https://energy-stats.uk/blog-summary/
Note: This website has no affiliation to Octopus Energy other than me being a regular and happy customer.

What are Time of Use tariffs?
Time of use tariffs (or smart tariffs) are the future of electricity provision. They are designed to encourage more energy use at off-peak times in order to balance nationwide demand.
By design, these tariffs offer cheaper rates at certain times of the day or night, usually when demand is at its lowest. Then charge a higher rate when national demand is higher.
The benefits are twofold; national demand is managed and spread throughout the day better and customers can lower their bills by shifting their usage away from peak times.
Time of use tariffs require Smart Meters. But this combination present the perfect use case and future state of operation for energy supply and demand. Smart meters track your usage every 30 minutes and time of user tariffs can change the price of electricity every 30 minutes too.
Octopus Energy are the main supplier in the UK that are rolling out Time of Use tariffs.
The website shows pricing from many of the Octopus Energy smart tariff options; Agile, Go and Cosy to name a few.
Check out the menus at the top of the website for regional pricing information.
