I've used silver saints a number of times and been very happy with their services. They have put together a cupboard, x2 chest of drawers, black out blind and most recently set up a hose piping system outside in our garden, they do electrical work also but i havent used them for electrical work. I've found them to be professional and polite.
Szymon has done most of the work for us and even helped move a large fridge/freezer when it wasnt part of the job spec.
good luck with your search
