This company is unprofessional. Seems to be run by amateurs who have zero business sense or acumen. They will promise you whatever you want to get the £50 fee for turning up. Will not do what they say. Will not reply to calls or emails. The engineers should not lawfully be allowed to use that name. A more fitting title would be cowboys. Do not let anyone from this company into your home. They have a substandard work ethic and have no customer retention skills. I believe the positive reviews are bogus. You have a choice of other great companies. Use this company if you have money to lose.
