2026 Healthy Streets Scorecard results
Hillingdon remains 32nd overall this year, with its final Healthy Streets Scorecard score rising only slightly from 1.38 to 1.44 out of 10. This small improvement is not enough to shift the borough out of the bottom two, and the core picture remains one of very limited delivery.
The borough recorded no change on LTNs, 20mph roads, School Streets, protected cycle tracks or bus priority. Its 20mph coverage remains extremely low at 8.0%, and Hillingdon still has only one School Street, covering less than 1% of schools. CPZ coverage fell slightly to 11.9% after the first data update in a couple of years, reflecting small adjustments rather than a clear policy change. Bus priority is also low, at 5.7%.
There are some modestly better outcome trends. The proportion of adults walking regularly increased to 27.3%, and cycling participation rose to 7.5%, although both remain low. The polluting-vehicle measure improved from 6.65 to 6.43. But sustainable modeshare fell below 50%, car ownership remains the highest in London at 103.9 cars per 100 households, and fewer than a quarter of households are car-free. Hillingdon’s results show a borough still heavily shaped by car dependence, with major gaps on safer speeds, School Streets, parking controls and everyday active travel.
The Healthy Streets Scorecard combines scores for ten indicators to create an overall Healthy Streets score for each borough. See the graph below for 2026 results (includes 2019–2025 results for comparison). For more detail visit the London-wide overview of the 2026 results. You can also:

Scorecard (factored score) chart explained
In the chart above, each borough has been given a factored score. Factor scores are composite variables which provide information about a borough’s placement on a scale. Factor scores are given by F=XB, where X is the indicator normalised score for a borough and B is the factor score coefficient (or weight). Each indicator is weighted as 1, or 0.5 if there are two parts to one indicator, for example Modeshare has a weighting of 1, Active travel – walking has a weighting of 0.5 and Active travel – cycling has a weighting of 0.5. The borough’s total factored score is the sum of all indicator factored scores which is then factored to 10 (multiplied by the number of indicators/10) to give a value on the scale between zero and 10. We can then compare boroughs against each other on the scale.
