Some Oxfordshire postcodes can expect postal delays today and over the weekend as the Royal Mail has issued an apology in advance.
Residents in Bicester (OX25 - OX27) can expect delays 'temporarily' due to sick absence, resourcing, or other local factors.
In a statement, a spokesperson for Royal Mail said: "We aim to deliver to all addresses we have mail for, six days a week.
"In a small number of local offices, this may temporarily not be possible due to local issues such as high levels of sick absence, resourcing, or other local factors.
"In those cases, we will rotate deliveries to minimise the delay to individual customers.
"We also provide targeted support to those offices to address their challenges and restore our service to the high standard our customers would normally receive.
"We're sorry for any inconvenience and thank you for your understanding. We will regularly update customers on the offices most impacted here."
In August 2025 Anneliese Dodds, MP for Oxford East, said she had 'long been concerned with the poor standard' of service from Royal Mail in her constituency.
She said at the time that despite 'numerous temporary fixes' being implemented over the years, the 'underlying issues have persisted'.
"They are now consistently delivering to more than 85 per cent of addresses six days a week, compared with 70 per cent of addresses at the beginning of the year, which is a good start, but still leaves 15 per cent of my constituents without the mail they need," Ms Dodds said.
