A Conservative councillor has written to all three of Milton Keynes' constituency MPs urging them to take action over ongoing postal delivery failures.
Residents in Crownhill, whose post is handled by the Kiln Farm Delivery Office, and Shenley Church End, served by the D ane Road Delivery Office in Bletchley, have reported going without post for up to ten days before receiving a large backlog of letters all at once.
Cllr Amanda Marlow, councillor for Watling Ward, says the delays are having real consequences for residents, with reports of missed hospital and GP appointments, delayed benefit and pension correspondence and bills arriving too late to deal with promptly.
Under Royal Mail's Universal Service Obligation, the company is legally required to deliver 90% of first-class mail the next working day and 95% of second-class mail within three working days.
Cllr Marlow believes the experiences reported by residents indicate those standards are not being met locally.
"When residents go a week or more without receiving any post, this is no longer a minor inconvenience," Cllr Marlow said, "People rely on the postal service for hospital appointments, financial information and important official correspondence. When those letters don't arrive, the consequences can be serious.
"I've written to all three MPs because this problem affects residents across constituency boundaries. I want them to work together to raise these concerns directly with Royal Mail and the Postal Affairs Minister so we can get to the bottom of what's going wrong and, more importantly, get it fixed," she added.
"I'm also going to visit both delivery offices to better understand the challenges they are facing. If there are genuine operational issues, we need to know what they are. Residents simply want a reliable postal service that delivers on time."
Cllr Marlow is calling for a coordinated response from Milton Keynes' MPs to press Royal Mail for urgent improvements at both the Kiln Farm and Dane Road delivery offices.
She says residents deserve confidence that important letters will arrive when they are expected and that the current level of service cannot be allowed to continue.
