Government announcement re: tiers from 2nd Dec - Christmas arrangements still to be announced

Does anyone have any experience reducing the solar gain from their windows and roof lights?  E.g. using window film, low u-value glass and/or external shutters? What and who do you recommend?  How much did it cost and when?  We have a fairly standard south facing ED terrace with Velux windows (internal blinds only), a roof light, uPVC double-glazed sash windows and wooden double-glazed french door all fitted 2015ish. Trying to future proof the house against future hot summers without resorting to air con.

I think these kids are starting to come from the park into residential road I live of a road very close to the park and just had a kid knock on door stood with his tongue hanging out clearly trying to intimidate and his friend was laughing. Is there anything  I can do in terms of registering it with the police ?   edit - called 101 and gave a very detailed  description (sorry I’d have deleted the post  if I could !)

Well, he’s just turned up. 17 days.  very thin and seems a bit traumatised. Presumably been trapped somewhere.  I’d love to know where! 

I contacted Niko based on ED Forum reviews and he lived up to expectations. I contacted him on Friday and we arranged for him to come check my faulty toilet on Monday morning. Within a couple of hours he had fixed the issue including going to buy the spare parts. He has a no nonsense approach and you know you are in good hands. Highly recommended.
