Train Ticket Inflation FAQ
Everything you need to know about UK rail fare increases, the difference between regulated and unregulated tickets, and how inflation impacts your commute.
In the UK, ‘regulated’ train fares (like season tickets and anytime returns) are typically capped to increase by the Retail Prices Index (RPI) measured the previous July. Since 2020, the government has sometimes switched the cap to RPI or CPI, and in recent years, fare increases have often been set at RPI or RPI+1%. ‘Unregulated’ fares can be increased by train operating companies at their own discretion.
The UK government usually implements annual fare increases at the start of the calendar year (January). This is done to help fund the railway network and shift the burden of network investment from taxpayers to the passengers who use the service.
Regulated fares are controlled by the government and their annual increase is capped by a specific inflation index (usually RPI). Unregulated fares are set by the train operators and can be increased by any amount, though they are subject to market competition. Most everyday commuter tickets are regulated.
Over the long term, yes. For many years, the government allowed rail fares to rise by RPI + 1%, meaning they consistently outpaced general inflation (CPI) and wage growth. In recent years, while the formula has fluctuated, the cumulative effect of annual increases has significantly reduced the affordability of rail travel.
You can use our Train Ticket Inflation Tracker. By entering the price of your ticket in a previous year and applying the average annual percentage increase over a period of years, the calculator uses compound growth to show you the exact theoretical cost and total percentage increase.
