Although the Ministry of Pensions (MoP) took over the functions of issuing pensions the work of Chelsea continued under the auspices of the MoP in respect of payment of pensions to disabled soldiers and those awarded a pension alongside a medal entitlement. Research in to the numbering ranges used by Chelsea demonstrate how these numbering sequences were used (and demonstrates how many cases were being processed).
The 'D' range
The issuing of Chelsea Pensions in 'D' range began prior to WW1 and continued up until June 1916
The 'E' range
The issuing of Chelsea Pensions in 'E' range began in June 1916 and was used through to February 1917.
The 'F' range
The issuing of Chelsea Pensions in 'F' range appears to, allowing for odd outliers, start in mid 1917. The range appears to have been used in respect of the Service Pensions, LSGC, DCM and VC pension and gratuity payments.
The 'H' range
The issuing of Chelsea Pensions in 'F' range began in February 1917 and was used through to March/April 1918.
