"If your basement is damp or at risk of flooding, it’s worth installing a sump pump.
If it’s dry and well-waterproofed, you probably don’t need one.
Typical UK cost:

New installation (digging + pump + drainage): about £1,500–£3,000

Replacing an existing pump: about £500–£800

Get a few quotes from local waterproofing specialists before deciding."
