I noticed on the Met Eireann Twitter account and website there was a mistake which stated if the UV index was 10 it was extreme. I contacted them using the form on their website and had emails asking me for evidence it was wrong. I took a screenshot from their website but they wanted more evidence so I took a screenshot from the World Health Organization website which stated the UV index is extreme if it is 11+. Met Eireann corrected it on their Twitter account and website before I sent the email and I am pleased it has been corrected but surprised by the mistake.
I have stated before the UV index does not exceed 8 in the UK as this is what I read on the Met Office website and DEFRA. I look at the Met Office website and the temperature forecasts are too low and this makes me think the UV forecasts are also too low. Two people on here have told me UV levels in the UK have been higher than 8 so I was wrong.

Away from coastal areas I think the UV forecasts are pretty accurate. I
am about 28 miles from the south coast (crow miles) and usually peak
summer is high 6s, maybe nudging a 7 very occasionally.

Here's a graph of my peak UV values by day for the past 12 months:
