Check the couple of old threads now linked via the tag under your post. No reason they shouldn’t still be in business.
I recommend John Lawler in Hornsey, he picks up & returns locally I believe.
Thanks EMC2, how can i get a hold of John, do you have a contact number?
Just click on the link (his name) in my post above Jamal.
Also for restoration to a high standard try Solomon 0208 348 9855 and 07752 377725. He has a shop called Solomon Retro in Park Rd Crouch End, and can do re upholstery, restoration of antique furniture and will pick up and drop off. Very good too.
