SHADE NEEDED

OP I feel for you . When it got to 40 DH nailed in some old sheets outside the house over windows and it was so amazing !
Just two small nails were enough to hold up sheets and over our back door. Our kitchen is the same as yours we get the sun at cooking time.
Having blinds inside helps but remember the sun is still getting to the glass so once you peventt that happy timea.
Easy painless cheap option.

Another more expensive idea is to get a sail fitted from Windows outside to fence or nest doors wall.

Sun canopy in the garden to block the sun from hitting the windows / doors. We have one well a few as we have a south facing rear garden with sun all day.

Also cold foods and if doing things like tuna pasta cook the pasta the night before when it’s cooler, rinse it and fridge it for the next day. We did a whole chicken the other day when it was cooler in the evening to then use in salad wraps the next day so all the hot stuff was done late at night for nice cold meals the next day.

@ClematisPurple item 3

you're in a house? You must be able to put something outside. I can't do that without a scaffold 😂

I taped white paper over my windows yesterday. It's made a big difference.

Perfect fit blinds from 24/7 blinds. They do a thermal option which keeps the heat out in the summer and in in the winter. They clip inside the UPVC frame so no trailing cords or anything flapping about

On a more helpful note than my last post, I bought this from John Lewis.

Originally it was to provide shade while sitting on my balcony. That's not what it does at all. The angle means it shades part of my front room, and does reduce the intensity during the day.

It is heavy weighted - in a storm or very heavy winds it may fall over but has never blown away.

The other things that help are blinds - any kind really. In my bedroom I have a blackout blind in a light colour that was bespoke from Blinds 2 U or whatever its called. Definitely helps a lot.

Then you need internal cooling. I have a turbo floor fan (from Robert Dyas for about £40). In one room I have an a portable Meaco air con which is good, but does require a window that the tube can pass through. There are smaller clip on fans on Amazon that can attach to tables.

Lastly a Cool Touch Ice Towel from Amazon round the neck.

Basically throwing some money at it unfortunately but if you can do it gradually over time it is worth it .

When you do have to be in there get one of those fans that go around your neck.
At least you'll get a bit of a breeze on you.
Put seriously - no hot cooking.
If there was ever a time for microwave meals - this is it.

Oh dear that sounds horrific! I have no helpful advice but poor you

Could you maybe tape one up somehow with really strong tape.
Or attach it on the outside - nails in the bricks as others have suggested.

Item 1

can you afford a portable air con unit? Years of trying stuff in a high rise flat facing south west - waste of time and money. Portable air con will get you from about 32 to 27 degrees.

also i stuck cardboard on the windows in the 2018 heatwave.

item 2 - don't be cooking.

they just stick onto the pvc

Quick cheap temporary, buy a roll of window film. It's meant to give clear glass a frosted effect. You cut it to size, spray the window with water, peel off the backing and hang it on the window like hanging wallpaper. Use a squeegee to get rid of air bubbles. It cuts the worst of the glare out, and some of the heat. You might want to leave a window clear to still have an outside view. I think I got mine from b&q I'll check

I can sympathise, we have a huge glass wall facing south into our kitchen diner. What helps is planning no cook/minimal cook meals. We are living off hot smoked salmon (open the pack and put on plate) with microwaved tender stem broccoli (3 mins tops). Or a ready cooked chicken and a pack of ready cooked lentils warmed up in 45 seconds in microwave. Lots of variations on this. If I had to stand in the kitchen longer than 5 minutes I think I would go mad.

Prepare just one meal for everyone rather than cooking for your Dc and then yourself later. Make easy and quick food, with lots of cold dinners, a r prepare the meals earlier in the morning when it’s cooler. No need to stand for ages in a hot kitchen cooking hot food.

Calm down for a start. If you’re broke, go to
tbe charity shop and buy a big duvet or table cloth or something, and then nail it to the outside of your window. You’ll be ok. Dont cook hot stuff in the heat, cold foods only.

Can't do a link for some reason but they're called SCHOTISS and available on amazon - £7 each. You can use them side by side full size or cut them down to be narrower.

You nail it into the brickwork above the window and the door.

You ate your neighbour? 🤣 Sorry, made me laugh.
I would suggest an awning and a white blind, plus a fan.
Do you have an air fryer? Microwave? Using the oven will make it even hotter.

I see your west facing and I raise you south facing new build 😂

It was 26 degrees outside at 8pm.

The corridor, yes corridor, outside my flat is 30 degrees at 10pm.

I’ve bought some stick-on paper blinds for my windows as a temporary solution. They keep out the sunlight and it stays cooler. Also close windows when it’s very hot.

And yeah, fuck cooking in this heat. Sandwiches and salad for tea here!
