Planning permission?

Not required; permitted development for under-stair WC

How long does it take?

0.5–3 days typical, plus design and approvals time beforehand.

DIY vs Professional

Difficulty: Pro recommended. UK building regulations and Part P/Gas Safe rules mean most of this work must be done by registered professionals. Even where DIY is permitted, paying a pro is usually faster and more reliable.

How to save money

• Buy the toilet from Screwfix or Wickes trade — typically 20 % cheaper than DIY shops
• Choose a rimless pan — easier to clean and looks better
• Always replace the wax seal at the same time — only a few pounds extra
• Wall-hung toilets need a sturdy stud wall — check before ordering
• For an under-stair WC, get a soil-pipe expert to confirm a gravity route before quoting
