A death must be registered by the Registrar of Deaths in the district in which it occurred within 5 days unless the Registrar says that this period can be extended.
If the death took place on the mainland relatives should contact the Register Office in the district where the death took place. For Treliske or West Cornwall Hospital, the Truro Register Office should be contacted on 0300 1234 181. For Derriford Hospital contact the Plymouth Register Office on 01725 268331 for instructions.
The Isles of Scilly Registration Service operates an appointment system for completing Registrations of Deaths occurring on the islands and will try to accommodate bereaved relatives as soon as possible.
The Registration service offers bereaved relatives the Tell Us Once service to help them contact government departments following the registration of a death. Full details and a list of documents required can be found on www.gov.uk/register-a-death
