The main Post Office in Hammersmith is to open seven days a week.
The branch, within WHSmith in Kings Mall , will be modernised during a revamp later this month before its reopening.
The service, which will launch on February 26, will be provided from six counters, including four new style open-plan positions and two secure fortress positions.
Customers will be able to access the same range of Post Office and mails services, including international parcels, Special Delivery, Local Collect, home shopping returns.
The Post Office service will be available from: 9am to 6pm Monday to Friday; 9am to 5.30pm on Saturday and 11am to 3pm on Sunday.
Sonia Gajudhur, manager of the Post Office at WHSmith in Hammersmith said: “We are delighted to be welcoming customers to our newly refurbished branch. Local residents and small business customers will be able to access the full range of Post Office services during our seven day week opening hours .
“The open-plan counters make it easier for customers and staff to talk, and the seven day opening hours make it more convenient as people now have lots of choice as when to visit.”
The branch will remain open during refurbishment, which begins on February 20.
