I've copied a DCC press release below with further details:
People in County Durham are being urged not to lose their
vote as the deadline for registering draws near.
County and parish council elections take place on Thursday,
2 May and anyone wishing to vote needs to be on the electoral register.
To find out if you are registered, or to request a
registration form, contact Durham County Council electoral services on 03000 26
12 12 or email electoralservices@durham.gov.uk.
Anyone who is listed on the electoral register can request a
postal vote. You should also contact the electoral services team to apply for a
postal vote.
The deadline for returning registration forms and postal
vote applications is Wednesday, 17 April.
