I`m at present trying to pursue a plumber who had his own company he carried out work in October 2012(using 1982 consumer regulations), this company was dissolved 2014, but plumber started new company, new name with a partner, obviously new company are denying all responsibility and have a proper new registration number at companies house but the company number used on their website and paperwork is for the company previously dissolved, can this help me in any way. Work was on an extension for my disability all our savings used, now find downstairs shower room leaks like a sieve, upstairs bath cracked pipe work numerous other things wrong, he had also failed to seal outlet xhaust pipe from combi boiler they installed, boiler condemned until sealed. Plumber came in 9th of April fixed boiler (now saying he resealed it) promised to come 12th april to sort all other issues now denying it, some help /advice would be very grateful.
