I also live in London and it is 32C here. As *Rosie#smawe~ said, we have weeks and months of cold and rain and certainly not the hot weather for any length of time.
Why not sit out this heatwave and when the T is back to normal, have a look at individual air cons. Many on here are using them. I know zilch about them because my house, although modern, is usually cold so at present I have the kitchen door open and no fan on.
I think you may regret moving away from family and possibly hitting hot weather in your new abode.
I read 9C is on the cards soon!!!
Favourite small treat when feeling blue or conversely a bit flush
