# Tariff Tracker > A free UK reference for every regulated and published price a household pays: energy, water, broadband and mobile, council tax, rent, rail fares, NHS charges, childcare, the TV licence and insurance. Every figure carries its primary source and the date it was set. Published by PEF Consulting Partners Limited, company number 16010640. ## If you are quoting these figures Carry the date with the number. Prices here change on published timetables and a figure with no date attached is worse than no figure. Every page has a section saying where its figures come from and where they could be wrong, and every API response carries the same thing as a caveats list. Please pass it on. This site publishes statistics only. It arranges nothing, quotes nothing and sells nothing. There is no insurance quoting on it. ## The API, which is probably what you want Open, free, no key. JSON by default, CSV by adding ?format=csv to any table. * [/api/v1](https://tarifftracker.io/api/v1): The catalogue. Every dataset, when each was last updated, and what it is for. Start here. * [/api/v1/benchmarks](https://tarifftracker.io/api/v1/benchmarks): What a typical UK household pays for each of the ten bills, with the source and the date the figure was set. * [/api/v1/prices/{vertical}](https://tarifftracker.io/api/v1/prices/energy): Everything behind one bill: the headline, the supporting figures, every table, the help schemes, the sources and the caveats. * [/api/v1/energy/tariffs](https://tarifftracker.io/api/v1/energy/tariffs): Every electricity and gas tariff we can verify, by region. Unit rate, standing charge, contract term, exit fee, and the cost of a year at typical use. * [/api/v1/energy/cap](https://tarifftracker.io/api/v1/energy/cap): The Ofgem cap unit rate and standing charge for electricity in each of the fourteen regions. What a default tariff charges, which is what you pay when a fix ends. * [/api/v1/lookup](https://tarifftracker.io/api/v1/lookup): A postcode turned into the things that decide your bills: electricity region, the cap rates there, water company and its average bill. * [/api/v1/changes](https://tarifftracker.io/api/v1/changes): What has already changed and the day it took effect. * [/api/v1/upcoming](https://tarifftracker.io/api/v1/upcoming): Dated changes that have not happened yet, flagged for whether the amount is published or only the date. * [/api/v1/trade/corridors](https://tarifftracker.io/api/v1/trade/corridors): Twenty nine trade corridors. Duty into the United States and duty coming back, layer by layer with effective dates. * [/api/v1/trade/programmes](https://tarifftracker.io/api/v1/trade/programmes): United States tariff programmes by legal authority, with rates, scope and who is varied out. * [/api/v1/trade/changes](https://tarifftracker.io/api/v1/trade/changes): The trade change log, including measures announced but not yet in force. * [/api/v1/broadband/deals](https://tarifftracker.io/api/v1/broadband/deals): Broadband packages costed across the whole contract rather than on the advertised monthly price, with the April rises the provider has already published built in. Ranked on what a package actually costs. * [/api/v1/energy/cap-history](https://tarifftracker.io/api/v1/energy/cap-history): The Ofgem price cap for every region and every quarter since it began in January 2019, on all three payment methods. Ofgem publishes the current cap and not the history: this took a Freedom of Information request, and these are Ofgem's own figures under the Open Government Licence. * [/api/v1/watch](https://tarifftracker.io/api/v1/watch): Every source this site cites, when it was last read, and when the figures on it last moved. Including the changes nobody has reviewed yet, because a reference site quietly going stale is worse than one that says where it might be behind. * [/api/v1/vouchers](https://tarifftracker.io/api/v1/vouchers): The claimable vouchers, discounts and free money a UK household forgets, each with the amount, who sets it and the official source. Shop voucher codes are a separate list that stays empty until a checked feed exists. * [/api/v1/prices/history](https://tarifftracker.io/api/v1/prices/history): What every household charge has been over time, one row per dated change, with the primary source that set each figure. The TV Licence, NHS prescriptions and dental, regulated rail fares and the average water bill. Nobody else keeps this. * [/api/v1/fuel/prices](https://tarifftracker.io/api/v1/fuel/prices): The official weekly pump price for petrol and diesel, thirteen weeks of trend, the tax inside a litre, the CMA's margin monitoring and the Fuel Finder scheme facts. * [/api/v1/ev-charging](https://tarifftracker.io/api/v1/ev-charging): Every large charging network's published prices from its own pricing page, read twice, one row per tier, with subscriptions, holds and overstay fees. Networks with per site pricing say so instead of showing an invented average. * [/api/v1/groceries](https://tarifftracker.io/api/v1/groceries): The ONS average price of 199 everyday grocery items, July 2026 against July 2025, with the reason no lawful per supermarket comparison exists carried in the body. * [/api/v1/council-tax/rates](https://tarifftracker.io/api/v1/council-tax/rates): Every billing authority's actual council tax, every band, all three banded nations in one table, each figure checked as an exact statutory ratio of its band D. Northern Ireland's rates poundages ride in the body. The spread the averages hide. * [/api/v1/rent/tribunal](https://tarifftracker.io/api/v1/rent/tribunal): The rent tribunal's most recent published decisions as data: current, proposed and determined rent, the regime, hardship, and a link to every decision. Since 1 May 2026 the determination cannot exceed the landlord's proposal, and these rows show it. * [/api/v1/installer-checks](https://tarifftracker.io/api/v1/installer-checks): The registers that say whether a firm may do energy efficiency, heating or renewable work on a home, what each actually guarantees and what it does not, which register covers which job, and the number format each uses. We hold none of these registers and this does not pretend to. * [/api/v1/home-upgrades](https://tarifftracker.io/api/v1/home-upgrades): Every UK grant and loan for insulation, heating and home upgrades, with its eligibility as testable conditions rather than prose, so software can answer whether a household qualifies and say which condition rules them out. All four nations, closed schemes included. * [/api/v1/energy/heat-networks](https://tarifftracker.io/api/v1/energy/heat-networks): How heat networks are regulated and what a customer on one is actually protected by. About 477,000 UK households buy heat from a monopoly they cannot leave, the price cap does not reach them, and Ofgem has only regulated it since 27 January 2026. Each protection carries its status and its date. * [/api/v1/water/charges](https://tarifftracker.io/api/v1/water/charges): What every UK water company actually charges: the rate per cubic metre, the standing charge, the rate per pound of rateable value and the assessed charges, read from each company's own charges scheme. No regulator collects these, because households cannot switch and so nobody has had a commercial reason to. * [/api/v1/support](https://tarifftracker.io/api/v1/support): Every grant, discount and protection for household bills. The eligibility conditions come as data rather than prose, alongside which of the four nations it covers, the deadline, what could not be verified, and where to apply. * [/api/v1/dictionary](https://tarifftracker.io/api/v1/dictionary): Every field in every dataset: its type, its unit, what it measures, and what a blank in it actually means. A null can be not published, does not apply, or not collected, and this tells them apart. * [/api/v1/sources](https://tarifftracker.io/api/v1/sources): Every source the site stands on, named and linked, so you can check any figure yourself.

Prescriptions are frozen. Dentistry is not. * [Childcare](https://tarifftracker.io/childcare/): Thirty funded hours if you qualify, and about £189 a week for a part time place if you do not.
