In these Rules, “unbroken service” means, subject to this rule, unbroken service as an officer of customs.

Part‑time service as an officer of customs for a period counts towards unbroken service, but the duration of service for that period is reduced proportionately.

A period of leave without pay —

A one‑day break in service for the purpose of awarding a pension or gratuity under the Pensions Regulations set out in the First Schedule to the Pensions Act 1956 —

Service as a full‑time national serviceman under the Enlistment Act 1970 counts towards unbroken service (even if it is not immediately followed by service as an officer of customs), but only if the service is for a continuous period of at least one year and 10 months.
