It comes as Royal Mail has listed 38 delivery offices as of Tuesday, that may be most affected by a slower service.
Yesterday (February 16), a spokesman for the company said that “adverse weather, including storms Goretti, Ingrid and Chandra in January, alongside higher-than-usual sick absence, has caused some short-term disruption to certain routes”.
The firm added: “We want to reassure customers that the vast majority of mail is delivered as planned and understand how frustrating it is when post does not arrive as expected.”

A Brief History of Royal Mail
On its website, Royal Mail explains: “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.”

Royal Mail questioned by MPs over ‘significant concerns’ about postal service
The latest list of postcodes affected by Royal Mail delays comes as a report by the BBC found that some letters were being held in delivery offices for weeks, leaving people to miss urgent mail such as appointment notices and bank statements.
Citing anonymous postal workers, the report said that parcels were being prioritised over letters in some depots, even if they are first class, while staff shortages were more broadly impacting the service.
It is understood that Royal Mail will opt to clear parcels first if they build up quickly and block walkways in delivery offices.
The company has said it is delivering more parcels as online shopping continues to grow, while the number of addressed letters going through its network is falling.
Royal Mail has now been given two weeks to respond to a series of questions put to it by the Business and Trade Committee (BTC).
The letter, addressed to Royal Mail’s interim chief executive Alistair Cochrane and sent on Monday raised “significant concerns about the quality of the postal service being provided by Royal Mail”.
It cited the postal firm issuing a notice about potential service delays across 38 of its delivery offices this week, covering more than 100 UK postcodes.
“This chaos has continued into mid-February, well beyond the predictable pressures of the Christmas period,” the letter read.
A spokesman for Royal Mail commented: “We have received the committee’s letter and will be replying in detail.
“We understand how frustrating it is when post does not arrive as expected and we want to reassure customers that the vast majority of mail is delivered as planned.
“Issues such as adverse weather and sickness absence have caused some short-term disruption to certain routes.”
It added that where delays do affect a route, it will move to bring in extra support to “restore deliveries as quickly as possible”.
