Any advice would be greatly appreciated. My vulnerable elderly father recently paid a builder £5k to instal a staircase in his house and, to cut a long story short, the job was horrendously botched. The work, which has now been reviewed by two further builders and an electrician, is unquestionably dangerous and unsound - exposed live wires, staircase the wrong width and length, gaping holes left in the walls, filth everywhere etc etc. It has now (weeks later) started to collapse: a wood support fell out and was revealed to be two pieces of wood glued together and held in place on the staircase by only three nails. So an open-and-shut case of incompetent and dangerous work.
I have written to and emailed the builder to request a full refund (including a letter before action), but have received no response. I will now report him to Trading Standards and initiate small claims proceedings, but am aware that he may not show up, already have CCJs against him etc.
Does anyone have any advice about any other legal steps I can take to pursue him, both in terms of enforcing repayment and to reporting him as a rogue tradesman?
