Royal Mail is to cut its late collection times at post boxes by almost half.
Between 45,000-50,000 of its 115,3001 post boxes will be moved to an earlier collection time.
Shadow business secretary Chuka Umuna described the changes as "disappointing" for customers and businesses.
Changes to collection times at thousands of Royal Mail post boxes adds "insult to injury" after its privatisation, the shadow business secretary said.
Up to 50,000 of Royal Mail's post boxes will be moved to an earlier collection time between 9am and 3pm.
"In their unnecessary fire sale of Royal Mail, the Tory-led government put vital postal services at risk and, as many feared when the privatisation took place, we are now seeing consumers losing out," Labour's Chuka Umunna said.
"This adds insult to injury after taxpayers were left short changed by hundreds of millions of pounds as the 'priority' City investors selected by the Tory-led government made a killing."
