The amount of money councils spend on road maintenance has fallen by £400 million over the past five years, despite councils receiving an extra £168 million in parking revenue.
Data obtained by consumer website confused.com found that councils collected £847 million in parking charges and fines during the 2017/18 financial year – up from £682 million in 2013/2014.
Councils’ spending on roads fell 21% from £2.8 billion to £2.4 billion.
Confused.com’s motoring editor Amanda Stretton said: “Parking charges and fines have put hundreds of millions of pounds into the pockets of councils.
“While councils are justified in charging for parking and issuing fines for illegal parking, our research found many motorists are confused about why more isn’t done to improve roads, given the amount of money councils receive in fines.
“Poor roads are a major concern for drivers, with roads riddled with potholes and unclear markings, it’s no wonder drivers want councils to be putting more into making these better.
“Parking and other charges are a huge burden on motorists, when the cost of driving is already very expensive. Those who think they have been fined unfairly are within their rights to challenge it.”
However, the Local Government Association (LGA) said council funding cuts from central government and that councils were already putting money raised from parking charges into road maintenance.
LGA transport spokesman Councillor Martin Tett said: “Any income raised through on-street parking charges and parking fines is spent on running parking services and any surplus is only spent on essential transport projects, such as tackling our national £9 billion roads repair backlog and other local transport projects that benefit high streets and local economies.
“This report completely ignores central government funding reductions. Between 2010 and 2020, councils will have lost 57p out of every £1 the government had provided for services, which is a much more significant source of funding for roads than surplus parking income.
“Surplus parking income is not the only source of money for roads and not all transport spend is spent on roads but can still be helpful to motorists, such as supporting concessionary bus fares to help reduce congestion.”
