Greyhound has become one of the most complained-about companies on the Pricewatch radar in recent months and we got several mails about it this week.

Readers are unhappy with its new charges for recycling. Until December it was free but now customers must buy branded recycling bags at a cost of €9 for six. The company blames “the high cost of distribution” of the bags and “the sharp fall in the market value of recyclables”. It is also refusing to collect rubbish in its old recycling bags as well.

Other readers who have left it in favour of City Bin have got in touch to complain about the waste disposal company’s €40 charge for collecting its own wheelie bins.

We also got another very specific complaint, that piqued our interest. “Greyhound changed the charging system last September offering three pricing options,” a reader called Eamon writes. “I opted for their Plan Two, pay per Lift, with a service charge of €60 per year and €6.50 per lift for the black bin up to a maximum of 25kg, after which a charge of 33 cent per kg applies. I figured, based on what I had been paying previously, that this was a good deal.”

In December he was told his black bin weighed 47.5kg and would cost €13.92. This was, he says, incorrect. How is he so sure? He keeps his waste to a minimum and is a keen advocate of recycling. He always weighs each bag of waste before binning it. “The bin contained five plastic sacks with a total weight of 32kg.” So he should have to pay for the weight above 25kg. “This would be 7kg at 33 cent per kg or a total of €2.31.” He says the possibility of a third party adding to his bin after it was left at the kerbside “does not exist as the bin was not taken out until a few minutes before it was collected”. He accepts that the money involved is “quite paltry” but he is still concerned. He points out that most people do not go to the trouble of weighing their waste so would not be aware if the charges were right or wrong.
