There are some minor problems in comparing the data for England and Scotland but you can be sure that were they to favour the former, they’d be widely reported. Here’s why they’re not:

Footnote:

Comparing median and mean ambulance response times can be useful, but each metric provides different insights, and their comparability depends on the data’s distribution and context. Here’s a breakdown:

• Mean (Average) Response Time: The sum of all response times divided by the number of responses. It gives a general sense of typical performance but is sensitive to extreme values (e.g., a few very long response times can skew the mean upward).
• Median Response Time: The middle value when all response times are ordered. It represents the point where half the responses are faster and half are slower, making it less affected by outliers and often a better measure of “typical” performance in skewed datasets.

In January 2024, BBC UK made direct comparison possible:

Via the BBC’s How long do patients wait for an ambulance? app, we can confirm that the average waiting time for a Scottish ambulance was 8 min and 46 secs: https://www.bbc.co.uk/news/health-59549800

Also, from BBC UK on 14 December 2023:

Average response times of more than 38 minutes for category two emergency calls such as heart attacks and strokes – above the target time of 18 minuteshttps://www.bbc.co.uk/news/health-67714151

Yes, I know the English figures are only for Category 2 emergency calls such as heart attacks and strokes and we can’t see if the Scottish figures are for the same or for all categories, but if they were for all categories including the less serious ones, that would make the Scottish average even more impressive!

I did expect not to find Scottish postcodes in the app, as is the case for Wales and Northern Ireland. BBC Scotland has since managed to get them removed.

They seem to have stopped offering this service in early March 2024 when the Scottish average wait for an ambulance was 8 minutes and 36 seconds but for England, they stopped posting the average to replace it with the percentage waiting more than 30 minutes – 27%. https://www.bbc.co.uk/news/health-59549800
