Rough cost of conservatory upgrade?

[MissAtomicBomb1]

After some advice please.
We're about to remortgage and we are thinking of having our conservatory roof upgraded so that we could use it as a room all year round.
Could anyone who's had it done give a rough idea of price please?
Depending on the cost we may be able to add in some bifolds, new flooring and other extras.
Would ideally extend but the costs are horrific at the moment so it's not something we can afford to do in the next ten yrs or so!

Pil had theirs done, I think it was about £7k. I can’t say it’s made a huge amount of difference.

We got ours down last year - 13k but that included the warm roof and all the doors and windows totally reglazed (basically rebuilt from dwarf walls up).

For us it was great - I use it as my wfh space , as a little exercise/yoga space and a lovely place to read my book in a big comfy chair. Totally worth it - whilst temps do get a little high/low, nothing opening a window or grabbing a blanket can't solve.

Depends on size but circa 8-9k

Thank you. That helps with a rough idea!
