Yes it's a manual station that I had missed in my initial roundup. I don't know if it's new as it does not appear in the list of Met Office station locations at https://www.metoffice.gov.uk/research/climate/maps-and-data/uk-synoptic-and-climate-stations.
Pitsford also shows up in that report with the highest temperature on Monday 18th, with 38.2C, which beats the highest announced at the time, Santon Downham, by 0.1C.
BTW to answer the question about 30C days as far as I can see there have only been 8 in July so far:
10 July 30.1C St James's Park
11 July 32.0C Northolt
12 July 31.7C Wisley (+ 33.2C St Helier)
13 July 30.1C Gosport
17 July 33.0C Hawarden
18 July 38.2C Pitsford
19 July 40.3C Coningsby
24 July 31.7C Weybourne
Plus 1 in June:
17 June 32.7C Santon Downham and Heathrow (+33.2C Jersey Maison St Louis)
BTW I wouldn't necessarily say that's the end of the heat for a while - 6Z GFS has 30C this coming Sat, Sun, Mon and Tue, so we could squeeze in two more in July!
