Policy worthless- avoid at all cost

I bought a new home from the developer Excelsior in 2013 who claimed to have won "best small development" from Premier Guarantee (later I found out that this was a lie). The house had numerous serious faults which Premier Guarantee failed to resolve despite clear terms in the policy that they were obliged to do so. Needless to say the developer was awful as well. It has taken 4 years of legal wrangling, stress, time and my money to have the problems rectified. Premier Guarantee have been found to be at fault 3 out 3 times by the Ombudsman yet despite this fail to acknowledge they have done anything wrong. It is unbelievable that these companies can function without strong regulation and scant concern for their customers. I would urge anyone who has a problem with this company to refer them to the Ombudsman- the Ombudsman is helpful and and easy process to follow. Maybe if enough complaints are made this company may take notice of its customers.
