Now, I don't know about you lot, but for me shutting the windows on
a bloody hot day like today is the LAST thing I would consider to
keep my house cool with!!


Then you need to take heed of the Met Office's advice and my earlier
comments in another thread. To save you searching for it I'll repeat
the advice. Have all the windows open during the coldest part of the
day (around dawn) to cool the house down. If you can safely leave
some windows open overnight this will help. When the external
temperature rises to a point near where no further cooling of the
house can be achieved, probably by nine o'clock, close all the
windows and close curtains on the sunny side of the house. This way
you should be able to maintain a temperature several degrees lower
than outside. Opening a window in the middle of the afternoon will
only heat up the inside of the house. If you want to feel the
refreshing effect of air movement, get a fan.

The temperature in my house is currently 26 downstairs and 28
upstairs. I have no windows open. A couple of hours ago, according to
Martin Rowley, the external temperature near here was 32 degrees and
I suspect it's higher now.

Yes this routine works well for me. With the living room on the north side
of the house I close windows and door about 9am and the temp in this room at
least remains about 4deg below outside. I then open everything up in late
evening.
