Severe thunderstorms broke out in a line from Sussex to the Wirral on the 22nd of July 1925. At Woolwich at about 6.30pm, hailstones the size of a man's fist were reported and weighed over 8oz (226g+). Unsurprisingly, there was extensive damage.

'Inmates' - not sure we'd approve of that being used to describe householders nowadays!

According to Philip Eden, the largest authenticated UK hailstone - 10cm across and weighing 141g - fell during a memorable storm at Horsham on 5th September 1958. Eden had the largest hailstone on 22nd July 1925 measuring 6cm across.

Looking at the reanalysis, no surprise the storms became this severe. Potent cut-off low with a very warm and evidently unstable airmass moving up from France. Probably decent shear mixed in as well. I believe this one is called a modified or easterly Spanish plume.
