The council department responsible for waste collection, street cleansing, car parking and markets received the highest number of complaints from members of the public in the Lancaster district, figures show.
Almost 80 per cent of complaints upheld by Lancaster City Council between April 1 and September 27 this year relate to its environmental services department, which also looks after grounds and general maintenance and repairs.
In total, 92 complaints were made, 48 of which were upheld.
Environmental services, headed up by chief officer Mark Davies, accounted for the bulk of this, with 39 upheld complaints.
The main issues were neglect or unjustifiable delay (25 complaints), and failure to follow procedure (18 compaints). Other issues were the unhelpful attitude of an employee (nine complaints), and failure to take account of relevant matters (six complaints).
Health and housing received 18 complaints, regeneration and planning seven, resources five, and governance, four.
City council leader Coun Eileen Blamire said: “Services that we all use like waste collection, cleansing and car parking deliver a huge amount of transactions each day.
“The number of complaints we receive represents a tiny percentage of these transactions.
Together with the vast range of other services provided each and every day, including car parks, street cleansing and grounds maintenance the fact there have only been 39 upheld complaints is remarkable.
“I am more than happy to say that the figures reflect the professional way the council’s workforce goes about its job.” On the very few occasions we get it wrong we put it right as soon as we can.”
