Royal Mail has escaped action over complaints that some final mail collections take place as early as 9am.
But the postal giant has agreed to review all its morning collection times following an inquiry by regulator Postcomm.
It was launched last October after residents in areas including South Wales, Derbyshire and Ipswich complained that final collections were being made before their post was delivered.
The Postcomm probe found there was no widespread problem with collection and delivery times.
But it said that 9am final collections were ‘not meeting customers needs’
Postcomm chairman Nigel Stapleton said: ‘Royal Mail has responded positively to Postcomm’s consultation by agreeing to review all of its morning collection times.
‘We expect the company will strike an appropriate balance between the needs of all mail users and the cost of satisfying such needs when it makes changes to current practices.
‘The research has found a generally high level of customer satisfaction with the services provided by Royal Mail and that, overall, most people are satisfied with current collection and delivery times.
‘For this reason, Postcomm have decided against taking any regulatory action at this time. We will, however, keep these collection and delivery issues under close scrutiny.’
