Economics
Inflation
Compare how the UK inflation basket changes between years, explore prices by category, see household costs relative to after-tax income, and build a basic basket with your own spending and replacement allowances. Explore income, bills and fiscal drag over time, with separate earners, children and tax-trap scenarios.
UK exports
A visual story of UK exports since 2015, from the COVID fall to services overtaking goods and goods to the EU after inflation, with a guess-first chart. Then explore every market quarter by quarter, drill from destinations to countries or from services to categories, compare goods and services growth by country, look at food, and try a what-if for extra sales and UK value added.
Who the government funds
Who central government gives grants to, from the Cabinet Office’s Government Grants Register: £229 billion to councils, schools, universities, charities and companies from 2019-20 to 2024-25. Split it by department, sector and year, see which think tanks and campaign groups get public money and how they lean, and which recipients have MPs or peers in declared roles, give to parties or meet ministers.
Follow the money
Every donation, gift, meal, ticket, paid-for trip and paid job declared by MPs since 2019, and every donation declared by the political parties, traced from the kind of donor to the donor, the party and the MP. Click through any sector, company, party or MP, look at the energy industry on its own, and check every entry against its source.
NHS trust executive pay
Salaries and pension-related benefits for the board directors of England’s acute NHS trusts, from each trust’s 2025/26 annual report, set against NHS England’s league table. See who is paid most, whose pay rose fastest, and whether better-paid boards run better-performing hospitals.
Heat pumps
Heating costs by SCOP
Compares the running cost, payback and CO2 of heating systems, from an old oil boiler to a well-installed heat pump, at today’s energy prices or your own. It shows what a heat pump saves at each SCOP against what you have now, and can work out your yearly heat use from your home’s measured heat loss.
Energy
Solar and battery savings
Takes your real half-hourly electricity use from your Octopus Energy account, or a demo household’s, and works out what solar panels, a plug-in balcony kit or a home battery would have saved you on your actual tariff.
GB electricity costs
Explore wholesale prices, household bill components, policy costs and generator revenues from February 2019 to September 2026. This beta dashboard separates the different costs behind the electricity bill.
Regional electricity prices
Compare what electricity would cost in each region of Great Britain if regions paid their own constraint costs, carbon tax and subsidies. This beta tool updates daily.
North Sea oil and gas
A map of every UK offshore oil and gas licence, with how much each has produced and what is estimated to remain. It compares the regulator’s, the industry’s and a climate think-tank’s estimates of what’s left, turns each into years of UK supply, and projects the tax it could raise at prices and tax rates you choose.
Biofuel land use
How much British farmland, food and subsidy it would take to replace a share of the gas grid with crop biomethane, or of petrol with crop ethanol. The land fills a map of Great Britain at true scale. It compares burning the fuel directly with running it through a power station into heat pumps or electric cars, and with putting solar panels on the same field.
Contracts for Difference
What every UK Contract for Difference has paid out so far, from LCCC’s settlement data. Pick technologies, allocation rounds and years, in cash or today’s money, and see net payments, the cost at strike prices, strike prices against the market price, and every contract in a table you can search, sort and download.
Nuclear vs renewables
What each GW of the UK’s nuclear fleet, offshore and onshore wind, solar, hydro and biomass has generated each year since 2009, how steady that output is from day to day and half-hour to half-hour, and what Hinkley Point C and Sizewell C would add at their higher capacity factors. Change the years, capacity factors and start dates and see how many GW of wind or solar it would take to match them.
Contracts for Difference map
Every Contract for Difference on a 3D map of Britain: the wind farms, solar parks, biomass plants and tidal turbines running now, and those agreed but not yet built, Hinkley Point C among them. Pick technologies and a year, see where the money went and where it came back when prices spiked in 2021 and 2022, zoom in to find each project, and open any of them for its output, payments and the output the grid turned down. Set a wholesale price to see what the contracts may cost until the 2040s.
Transport
A40 roundabout CO2
The extra fuel and CO2 from every car, van and lorry braking for the West Witney roundabout on the A40 and accelerating back up to speed, from the DfT’s traffic counts for that stretch. Change the speeds, weights and how many have to stop, and see the total each year since it opened in 2018.
