Royal Mail warns of delayed deliveries of letters and parcels in UK postcode areas - full list of affected postcodes
Royal Mail has issued a warning to thousands of homes across the UK over delayed deliveries.
Homes in areas across the country are being told that deliveries for letters and parcel may face delays due to issues such as staff sickness and resourcing.
Postcodes in cities such as Glasgow, Hull, Leicester, and Sunderland are among those affected.


Royal Mail said in a service update to customers: “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.”

Royal Mail also said that weather can have an adverse effect on the ability to deliver letters and parcels to homes. Recent, snow, ice and wet conditions have seen the Met Office introduce multiple weather warnings over the past week, as well as flood alerts issued by the Environmental Agency.
The mail service said: “During adverse weather, such as snow, icy conditions, or flooding, we may sometimes be unable to safely access certain streets or addresses. When this happens, we may need to temporarily adjust or pause services in those areas.
“Because the weather can quickly change, we continually monitor the conditions and undertake risk assessments to ensure we’re doing all we can to maintain mail deliveries and our other services, while protecting the safety of our posties - which is our priority. Please be assured, we will do everything we can to maintain and restore services where it’s safe to do so.”
