New kitchen

a plug in hob (ours is IKEA) makes everything easy planning wise, or you could get a multi cooker or rice cooker, but like PP we found the washing up the biggest pain. We had multiple washing up bowls so we had one for dirty, one for clean, maybe one for dry as well.

I would suggest starting with mainly home cooking and keep the takeaways in reserve for when you "need" them later on. Some nights we found ourselves painting etc so def needed takeaways those nights. Couscous, bread or microwave potatoes for carb, salad bag and cherry toms for veg, deli ham/chicken , scotch eggs or rotisserie chicken etc.

I factored in the expense of takeaways/eating out into the cost of our new kitchen.

Do what you gotta do!

And don’t get me started on the cost of the laundrette £8.50 a wash 😮 for a 12kg machine and £5 to tumble dry it! When you are living in a building site your clothes, towels, bedding get dirtier and dustier than normal.

We went about a month without a kitchen. As people have said the self leveling stuff takes a day at most. Cook meals are fine supplemented with salads etc. Bigger issue is the washing up. Paper plates/bowls/cups for cold drinks.you can get ones that compost easily. So only had mugs & cutlery/ odd bits to wash. We had water pipes moved etc. But were never without water (no water no loo!) Once the builders left for they day. They also rigged up my washer asap, so that was a bonus.

We had just under 3 weeks of this.
We batch cooked and used microwave or air fryer but it was much harder than i anticipated . The washing up was the hardest. We gave in for the last few days and ate out.
Do whatever makes your life easy.
I love my new kitchen but i never want to endure that again!

Had our kitchen done in the summer and apart from a cooked chicken from the supermarket with salad and fresh bread once or twice we ate out/got takeaways. The washing up, cleaning up, prep was just to much with all the mess the kitchen refit was already causing. Ours was due to a flood so my entire downstairs was a right off so a large renovation in reality maybe that made it all a lot worse I don’t know, it was horrendous worst 16 months of my life and it has permanently put me off any type of renovation ever again. We didn’t have the storage issues though as everything we owned was destroyed so I guess that was a bonus.

You should consider a remoska.Its so easy to cook and entire meal in the larger one and they're quite airtight so you're not getting condensation issues or a lot of cooking smells.My kitchen was replaced 25 years ago and hopefully won't need updated again as it's freestanding and items can be replaced individually.
Dishes were a massive problem and I always remember the bath being full of dishes.Your situation will require a lot of good humour and planning but I'm sure it's all going to be worth it.

Stand your fridge freezer on cardboard to protect carpet if you move it. Use paper plates so you don't have to wash up as much. When our kitchen was redone the dishwasher remained in the middle of the room plumbed in.

Since you have a microwave, I would err towards using ‘Cook’ meals rather than takeaways and supplementing with salads or microwave veg. At least most of them resemble home cooked meals.

To go without for a week is a pain. When I was 18 and still at school we had a grant to bring the house up to modern standards (dad was disabled and we applied when mum had just died). The building company was a partnership and one fucked off with the money. Fair play to the other guy he finished the job... but we didn't have a kitchen for a year. Not even a room. For months the cooker was a camping stove, a microwave and a deep fat fryer...under a wooden cover with a tarpaulin over. We had a fridge and freezer in the lounge and the kettle too.
We survived.

We've got one of the, they're great.

We used camping stoves and they were really easy, with all the other bits you've mentioned (air fryer, slow cooker), we didn't actually find we had to change diet that much! I just tended to cook meals that used less washing up

Three weeks is nothing! We were without a kitchen for 10 months, and whilst it wasn't easy, we coped ok.

I had a kitchen set up on my dining table.

I bought a two zone portable induction hob from Ikea (think it was about £80), and bought a stand from Amazon and put the air fryer on the bottom, and the microwave on top.

With those, plus a slow cooker, an electric steamer, a kettle and a toaster, we could cook everything, including roast dinners.

But to answer your question, no, you'd not be unreasonable to have loads of takeaways, as it's for such a short time.

Enjoy your new kitchen when you're in ! 😃

Currently in the thick of it! Paper plates are helpful. The lack of water downstairs will be the most problematic.We've got a fridge in (what was/will be again) our dining room, and it has a big jug of water in that we use for filling the kettle. Don't assume that the dust/mess will be limited to the area the trades are working in, we've got laundry piling up everywhere, brick dust travels everywhere (from chasing in new electrics) and our bins are currently in the dining room. I quite hate it! We do have a camping stove, toastie maker, slow cooker, microwave and very helpful mil who has made us a few meals though.

We just had microwave, kettle and toaster. I did have the fridge freezer in the room, so just batch cooked stuff and bought ready meals to microwave for the 3 weeks. You can get pre-cooked rice pouches etc. I found the worst bit was having to wash up in the bath meant it got food grease and then we wanted to wash there.

Do be careful with camping hobs as they should be used outside. Plug in ones come without the risk of carbon monoxide.

Find a local launderette.
Go for a couple of meals with family/friends/in a restaurant.
