Looking at the past 5 years locally, 2013 and 2014 were warmer than average, 2015 was average while 2011 and 2012 were pretty bad.
However, what's been noticeable is that even in months when temperatures were average or slightly above, sunshine levels have been low - August has been a bad month in particular for sun in recent years, though June and July have been bad as well. This is true nationwide as you will see by looking at the sunshine stats for Heathrow since 2007 vs the 1981-2010 averages.
Oh, actually, it appears 2012 was within the realms of average temp-wise, even though it felt worse than 2011. June was very, very wet. August was alright.
