Hallo Sue,
Also pasted from the Essex RO website:
"The Colchester and North East Essex Branch Office is now closed.
The Branch office closed at the end of March 2007.
The archival documents are now being transferred to the Essex Record Office at Wharf Road, Chelmsford, where they are expected to be available from 16th April onwards.
Please note that the Essex Record Office at Chelmsford will be closed from Tuesday 10th April to Saturday 14th April in order to undertake this move as quickly possible. More information about this temporary closure may be found on the front page of the Archives and Museums pages of this website. It is not necessary to book seats in the Searchroom at Chelmsford, but, for an initial period, users are advised to phone 01245 244640 or email
ero.enquiry@essexcc.gov.uk if they wish to see material formerly at Colchester, to avoid delay in retrieving it. The microfilm and microfiche at present on open access in the Searchroom at the Branch will be transferred to Colchester Library, where it will be available from 10th April onwards. Copies are already available in the Chelmsford Searchroom. We apologise for any inconvenience that may be caused during the transitional period."
I hope this helps
