Relocate a bathroom

[Futurepast]

I’ve been offered a council house which I have no choice but to take.
The problem is there’s a fair few things that needs doing.
Though I don’t mode the work and cost can be managed I have no idea where to start when it comes to planning permission.
I know all councils are different but here’s my problem - the bathroom is downstairs but there’s a box room upstairs that’s actually a good size for a small bathroom.
I’d like to put a bathroom upstairs and take out the old one to make a playroom for my daughter.
I know I have to ask planning permission first but they’ll want to know the proposals and who I’m using. But how do I book someone to do the job when I have no idea when or if they can do the job. On top of Google says that I need to contact building regulations but when I spoke to someone at beyond housing they made it sound like they do that themselves.

If anyone has been though a similar process or has any idea where I can start I’d be deeply grateful ☺️

I would start by finding out (in writing) whether you are allowed to make changes of this kind, particularly as removing a bedroom (if I read you right) even if it's a box room will have an impact on the value of their asset.

You don't usually need planning permission unless you're changing the look of the outside of a house - eg adding a room over the garage.
Moving a bathroom would be fine, though difficult. Is the downstairs bathroom anywhere close to the upstairs room you want to move the bathroom to? It gets expensive when you have to reroute pipes, particularly the toilet outlet.

They didn’t include it as a bedroom as they said it was too small but I thought big enough for a small bathroom.

Yes it’s directly above the kitchen and the current bathroom is next to that all at the back of the house.

You are unlikely to be given permission to remove a downstairs toilet as the current regs will be based around wheelchair access and you are downgrading a housing unit.

If you are adding in an upstairs bathroom over the existing one it would be easier as it will connect to the existing drains /water pipes. You still need to comply with the building regs so google will give a load of detail on what is needed.

If it’s a council house which the council owns and you pay rent then you can’t do anything like that as you don’t own it.

If you mean it’s an ex-council house that you bought then you’ll need planning permission. However removing a downstairs toilet is often not allowed unless you are relocating it somewhere else downstairs.
