£100 in 2000 is worth £187.47 in today's pounds, adjusted by British consumer-price inflation (UK CPI), which rose 87% since then. ONS / FRED data through March 1, 2025.
By 2000, £100 was a routine everyday sum, and inflation had calmed to below 3% under the inflation-targeting regime adopted after the 1992 ERM exit, with the Bank of England independent on interest rates since 1997. Prices still rose steadily over the years since. Matching the purchasing power this amount held then takes a moderately higher figure in today's pounds.
UK CPI before 1997 splices the historical retail-price record. Values are in pounds sterling, continuous since the 1971 decimalisation. This tracks consumer-price inflation, not exchange rates or investment returns.
