Utterly atrocious company to deal with! Salesman promised the earth and the company cannot deliver, DO NOT BE FOOLED. Salesman came to do a second quote after other companies quoted less, funnily enough the second quote was just under competitors'. Promised a call back that day from head office to arrange an initial assessment the next week for installation the week after, NOBODY CALLED. Rang at the weekend to find out nobody to book an initial assessment was there (but they happily took £100 deposit) and promised a call back on Monday, NOBODY CALLED. On Tuesday, NOBODY CALLED. On Wednesday I called them again to be told the singular person who can book the appointment was busy and would call me back, NOBODY CALLED. On Thursday I called again to once more be told this individual person was busy. I said I'd wait on the phone for them to be free as I did not trust they'd call back but apparently they do not allow this (rude staff, very unhelpful). Asked to speak to a manager instead, also not allowed, they will only schedule call backs.... After some persistence they mentioned a date for an initial assessment in three weeks time! Having no heating or hot water this was obviously unacceptable and was not agreed previously. Asked for the deposit back and that was a straight no. I booked another company to do the work who could do it the following week and suddenly they wanted to talk again, offered next day assessment and promised a date for installation the following week. I felt as though they were just trying to keep me on the hook and declined, they did agree to send the deposit back at this point after consulting a manager (it took 2 weeks to receive the deposit back). Turns out they used to be Valley Heating Services which has far more negative reviews than 50Five. Do your own research. In conclusion, one of the worst companies to deal with I have ever encountered. If I could give less than one star then I would. I would not trust them to stick to any date or ever call back.
