We've just become the proud owners of a stone-built house in West
Yorks. It has a sizeable basement we'd like to convert into a kitchen.
It's ideal for it as the house is built on a slope. The front door is
at street level. The basement is at garden level with a door and
window looking out.

What are the options for damp-proofing to make it habitable?

Is it a DIY job or is it better to pay someone and have a guarantee
for prospective future buyers?
The latter I think although www.sovchem.co.uk has plenty of technical info.
