The North London branch of CPL (Archway branch) won't rehome kittens to indoor homes but will sometimes rehome cats indoors particularly if they are already indoor cats and seem suitable for such rehoming. They never answer the phone so email is best (their contact details are on CatChat rescue pages...).
As others have said, blind or deaf cats in some London rehoming centres (such as HAWS) are often given indoor homes.
Also worth considering FIV+ cats.
