Ulez: Vehicle compliancy rate at 95% across London, City Hall report says

Ulez vehicle compliancy has reached 95% across inner and outer London, according to a new report by City Hall.

Data shows since the Ultra Low Emission Zone (Ulez) was expanded to cover all of London, vehicle compliance in the outer boroughs rose from 85% to 95%.

Mayor Sadiq Khan said the data showed the scheme, which aimed to improve London's air quality, was working.

But the Conservative Party said based on the report's data, the expansion had earned £52.5m, making it a "tax grab".

The report, on the impact of Ulez since it was expanded on 29 August, also found:

Responding to the report, Labour's Mr Khan said: "I've always said that the decision to expand the Ulez was very difficult, but a month on from the expansion we can already see that it is working."

But the Conservative Party said the scheme was a "tax grab".

Its analysis of City Hall's data found that on average, 57,200 vehicles paid the Ulez charge of £12.50 every day, which, from 29 August until 30 October, had brought in £44.3m.

The Conservatives added an estimated 2,696 vehicles per day were fined £90 over 34 days for not paying the charge, bringing in an additional £8.2m.

Susan Hall, the Conservative mayoral candidate, said: "To take over £52m from hardworking people, with no gain to air quality described anywhere in this report, shows how little he cares for Londoners.

"It is those on the lowest incomes who are suffering most from this disastrous charge."

The mayor's office and TfL have been approached for comment.

What the figures show is the London fleet has changed after the expansion of Ulez.

In a way, that isn't surprising as that is what happened in its previous incarnations - people don't want to pay £12.50 a day so they change vehicles.

While this remains a contentious policy, bosses at TfL will be delighted it has got many to switch.

While cleaner vehicles should mean cleaner air, we won't find out the impact on air quality for months.

More time is needed to gather and examine the data so what the expanded Ulez has done to air quality probably won't be available before the mayoral elections next year.

That means the Ulez expansion (if there was ever any doubt) will be very much a live political issue in the mayoral election.
