Planning Permission for decking

[furryleopard]

Our decking has been in place we think since the house was built or at least a good few years longer than we've lived here, we bought the house in 2019 and it definitely wasn't new then. It's about 2m x 3m. Anyway, the decking is starting to rot and it needs replacing. We are just planning to do it like for like, DH is very handy and was hoping to do it himself. Our issue is that our garden slopes, the decking is level with the back door and small bit of patio but at the end of the decking it's over 30cm high. I am assuming that means we'd need planning permission? The ground level doesn't mean the bit level with the door and it includes the slope? It doesn't count that we're just replacing an original deck that's been there ages?

as far as I know, a like-for-like replacement shouldn't need planning.

Never heard of planing permission for decking, but in all honesty,it's slippery when wet, inevitably rots. Why not go for some kind of paving.

The height measures from ground level, defined as the ground next to the house. So assuming your garden slopes away you’re fine ! This is in England but not sure where you are

Thanks, we're in England. It sounds mad but I'm not sure what ground level is because our back door is on a built up bit of patio so that it's level with the front door and the path round the house from the front to the back slopes down and we have steps from the path up to the patio and decking, so which bit is ground level? The front/back door or the path. I'm probably over thinking this whole thing and no-one else worries about planning for decking.
