CH POSTCODE areas, which include Ellesmere Port & Neston, had some of the country’s worst delivery records during the postal strikes and floods of earlier this year.
Latest half-year performance results from Royal Mail confirm this summer’s official and unofficial strikes and the widespread flooding seriously affected the quality of postal services throughout the UK.
Watchdog body Postwatch has used the figures to produce tables for the best and worst-performing areas of the country.
On average, only 85.1% of 1st class stamped mail was delivered next day from April to September. The target is 93%.
Heading the “Top 20” performers are the HA Harrow postcode areas around London with 89.9%.
But just sneaking into the “Bottom 20” are the CH areas of Chester and Deeside on just 83.5%.
Worst in the country was OX Oxford on 78.4%.
Judith Donovan, regional chair of Postwatch Northern England, said: “Given the floods and the industrial dispute, customers will not be surprised that Royal Mail’s performance has been seriously below par during the summer.
“There will, however, be a collective sigh of relief that the bad news is over and that the future looks distinctly brighter.”
She added: “Industrial peace between Royal Mail and the Communication Workers Union means the industry, after a step backwards, can take great strides forward.
“Next year, customers should expect Royal Mail to be announcing a much improved performance. That should help all of us to post with confidence.”
The first 24-hour strike took place on June 29. The last official industrial action was a 48-hour strike which started on October 8.
Royal Mail marketing director Alex Batchelor said: “We are very aware that our customers simply didn’t receive the service they deserve as a result of this year’s strike action by the Communication Workers Union – and we’re very sorry that they were let down.
“Customers are all too aware that strike action continued during the third quarter of the year which means that targets will also be missed for the autumn period.
“But last week’s vote in favour of our pay deal is good news for customers – it’s a green light for Royal Mail to invest in new technology and modernise our operations so that we can return to the record highs in quality of service reached in the last two years and build on that success for the future.”
