The Aylesbury Vale District Council (AVDC) area offices in Buckingham and Winslow are to close in May.
The AVDC office in Winslow Commununity Library will close on Wednesday, May 19, and the AVDC office in the Buckingham Centre will close on Friday, May 30.
However, the Buckingham Centre will remain open and will continue to offer its other services.
AVDC says the changes reflect the significantly reduced demand for a face-to-face service as more people use the its website or contact staff by phone and email.
It says there has been a steady fall in the number of people using the area offices, with fewer than 12 customers per day visiting with non payment-related AVDC enquiries.
Therefore, AVDC will no longer be providing customer access points in Buckingham and Winslow.
Cabinet member for community matters, Pam Pearce, said: “The way people access council services is changing and people tend to prefer contacting us either by phone or using our online services.
“It is clear from the visitor figures that maintaining face-to-face customer services in Buckingham and Winslow is not efficient or cost effective.
“Although there will be much more of an emphasis on self service, we will continue to offer face-to-face support at our Gateway offices in Aylesbury to anyone who needs it.”
An AVDC spokesman said the service offered to Vale residents will not be affected.
Customers will be encouraged to visit the AVDC website www.aylesburyvaledc.gov.uk as a first point of contact.
For the small number of issues that can’t be addressed online or for people without internet access, staff are easily contactable by telephone on 01296 585858.
If a query cannot be resolved by phone or email, the customer will be offered an appointment to see an officer at The Gateway in Aylesbury.
The spokesman added: “For the few people who may find it difficult to visit Aylesbury, some AVDC services may offer a local surgery or, where appropriate, arrange a home visit.
“In addition, there will be free access to a computer and telephone at Buckingham Citizens Advice Bureau in Wheeldon House, Market Hill, Buckingham.”
Payments can still be made at all shops with the Paypoint sign or at post offices. A list of locations is available at www.aylesburyvaledc.gov.uk/wheretopay For more information about the changes to face-to-face services, visit www.aylesburyvaledc.gov.uk/move
