And what would the ballpark figure be for such a hire (I know its a
vague question)?

If you go for an access tower (like SGB Boss) rather than scaffolding -
something around £100-£150/week for a 7m working height tower. Some
outfits may have delivery/collection charges on top, if you can't
transport it.

Access towers are great if you have flat hardstanding around your
house, otherwise it may require partial dismantling to move. Ask the
hire service about erecting them safely if you're not sure.
