This company provide misleading diagnosis for my boiler. They told me that my boiler to old and that this boiler can't work without new PCB (they charge me for diagnostic 78GBP), wanted to charge 1 x PCB = £389+VAT), also that no warranty that it works with new PCB - buy new boiler. After that I booked appointment with other company, which detect that my boiler lock out. They reset my boiler and now heating and hot water working fine without new PCB. That company which reset my boiler didn't charge me for that Now PLUMBFORCEDIRECT trying to find any reason don't refund diagnostic charge.
