Research by ITV shows that Barnet has the highest number of complaints about potholes in London - 1,722 in 2013 - and has spent £88,491 on compensation claims - the second highest in London.
The news comes after council performance data this month showed only 59% of unsafe or 'intervention level' potholes are made safe within 48 hours of being reported by members of the public - against a target of 100%.
The council's own Residents' Perception Survey showed that the state of roads and pavements was the number one concern amongst local people.
Barnet's Labour councillors have pledged to make better use of money the council has set aside for potholes and pavements by holding contractors to account for poor performance.
Labour's Envrionment Spokesperson, Cllr Alan Schneiderman said: "Barnet have had year-on-year of poor performance in dealing with potholes, and despite saying they are sorting it out the data shows this is not having much effect on the ground. We must make sure our roads and pavements are safe for everyone and that council tax payers' money is being spent effectively by properly monitoring, challenging and holding contractors to account for poor performance."
