AIBU to think we can renovate the whole house with £11k

I agree with this- I was amazed at how often I dropped £80 at Toolstation just for bits and bobs.
I think the budget is quite ambitious. Agree with PP I'd leave the doors until last.

What type of wallpaper is it? We've just ripped a load of woodchip off and the walls have had to go back to brick 🥴

If it is purely cosmetic and you aren't moving wiring or pipe work then yes.
You might be tight depending on how fancy your new bathroom is but it is definitely doable.

that sounds about right for LVT …..which imo is better option than engineered wood

I think things like polyfiller, tape, sand paper and mastic come to a surprising amount.

How old is your house? I think you need to go room by room and see what's under the wall paper or current flooring before you make any decisions to be honest. We had our bathroom done and although we were prepared for it (having done other rooms first) the textured wall paper was pretty much the only thing holding the plaster up! We had to take it back to brick. We didn't have expensive fittings, but still the cost for our bathroom was more than your budget (obviously including labour costs which are significant, but building materials in general are much higher than they used to be)

That’s very expensive laminate. I’ve just purchased 76m2 of 14mm engineered oak (2.5mm oak) for £2100 with the underlay.

Go to your independent high street carpet shop….always better value I’ve found

Ps. We're in a small mid-terrace.

We've recently had some of the jobs on your list done:

Wooden flooring for one room- £1200
Bathroom- £8000 (£1400 for the goods in the B&Q sale, the rest labour)
Painting the downstairs (2 reception rooms, kitchen, hallway, stairs and landing) £2800
We didn't replace any doors but our radiators for the whole house cost £1800

We live in the SE where costs for trades are through the roof.

We've been quoted £3000 for carpet on the stairs and three rooms upstairs from carpet rite.

Agree with these costs but would be cheap and cheerful

Yes, if it's just what you've listed I think that's very doable.

you mention that you get discount at B&Q, do you work for the kingfisher group? You might get discount at screwfix too, which tends to be cheaper than B&Q for fixtures/fittings

Obviously depends massively what spec & how big your house is, but conservatively:

Paint walls £500
Laminate flooring in 5 rooms and hall way £3000
New full bathroom and new tiles £3000
New internal doors £2000 and radiators £1000
Carpet on the stairs £500

May e you will do it but it will look basic and probably need doing again. However if you don't mind second had furniture etc then I would take time and do it when you can afford to do it properly. We just did a 3/4 bed bungalow with a new roof for 100k no bathrooms or kitchen just roof fireplace skimming and decorating

Having just done our house...mostly diy I'm not sure. Material costs are sky high at the moment. If you do it yourself possibly...suggest diy kitchens but you need to measure and remeasure as any mistakes are yours. You be shocked how much extra work you need to do without realizing cost. You need to do labour yourself and be a small house and nothing to shock you...our boiler failed and no hot water and that was 3k before we started...

Yeah this is often the problem and you’ll generally find (at least in older houses) that the walls are not in great shape underneath and need skimming. Have you factored that in? I was very surprised how much skimming walls costs professionally, but obviously if you’re able to do it yourself then awesome.

If you getting cheap laminate you will be fine…..if you want LVT eg amtico …then your budget won’t stretch….personally I would rather go at least mid quality and do a few room then save and do a more

Or how soon you want to redo it all again 😬

Very doable if you have free labour.

Yes….as long as you diy….and go use cheap materials…..depends how cheap you prepared to go though

Dont skimp on taps or shower.

Probably doable buying very budget materials but manage your expectations for the finished look. We’re renovating and just going slowly so we can get a higher end finish as this will hopefully be the last house we buy. It will be at least a 5 year project. If it’s for a house you are planning to live in for the foreseeable I would slow down a bit and extend your budget, especially for flooring once you’ve saved up some more money.
Agree with poster about cost of bloody taps too! In our last house we put in a lovely kitchen but cut costs on the taps as they are so dam expensive and it was the one thing that stood out like a sore thumb and looked cheap and crap!

It's the taps and shower valves and radiator and radiator valves and mirror and cistern and shower tray and waste bits etc etc and all the little bits that add the cost though. I was super surprised to find baths 'only' cost a couple of hundred quid when we redid our bathroom earlier this year!
