Please note

  • This valuation is only relevant if you cash in your Certificate in December. If you wish to cash in your Certificate in November please contact us by phone for an exact valuation as the value may increase or decrease depending on the change in the RPI
  • This valuation is for guide purposes only based on data last updated on 17 November 2009 and may not be exact
  • If you're not cashing in, interest and any index linking for the year are only added on each anniversary of your Certificate
  • If your certificate matured before 8th October 2001 and has not been cashed or reinvested, it earns index-linking only and no additional interest (except for 3rd and 4th Issues which earn 0.5%). You may wish to reinvest into a current Certificate for a better return. For details of the current Issues, go to our Interest Rates section

Certificates cashed in within the first year of investing don’t earn any index-linking or extra interest.
