I only wish it was possible to mark zero starts! Despite having an expensive maintenance contract in place with this company, I have now been WITHOUT HEATING AND HOT WATER FOR OVER 4 WEEKS, the temperature outside was -5 last night! Their customer service staff are rude and unhelpful and their engineers are totally useless. They have visited 5 times now (5 days off work for me) and still not managed to repair the boiler. Every time they attend they say they have to order parts, then they return to fit the said parts and they are the wrong parts. It is so cold in my house that the back door is completely frozen shut! I have never felt so let down by a company and I urge anyone who is considering getting their boiler repaired not to choose this company. They fix you into a contract for repair and then simply do not care about fixing the issue.
