No as it stands July 2013 trumps June 2018..
UK overview
Much of July was settled with high pressure established over the UK and with plenty of sunshine in most areas. As the month progressed there was an increasing tendency for high daytime temperatures, exceeding 28 °C somewhere in the UK on 19 consecutive days from 6th to 24th, with values exceeding 30 °C on several days. This was the UK's most notable summer heat wave since 2006. The UK overall had a rather dry month compared to normal, with nearly all of the month's rain falling during the last ten days, often as thundery outbreaks.

19 yes 19 consecutive days of 28C or higher.. and it was a nationwide heat wave.
33.5C was the highest temp that month and as far as I'm aware that has yet to be matched this June.
