Never used this company because they have spelt their name wrong it should be S... Heating. They have a lucrative contract with Clarion Housing, and they have worked out a great scam. They are paid for emergency callouts, and on arrival will turn off any appliances or water any leaks and leave!! They will then say sorry can't stay and do any work because I have more visits to do. I don't know why they bring their tools into the house because they have no intention of doing any work. I know people who called them out many times and this is always the case, sometimes leaving their client without heating or hot water for many weeks. They don't care because they've been paid, and will continually be paid many 10's of pounds just driving from customer to customer. I should imagine if they do 40 callouts a day, at £50 each, that's £1000 a day for turning off the water tap. You call Clarion Housing and they just say we have a long-term contract with Swale Heating, and therefore we cannot send anyone from another firm. Of course private clients, would just refuse to pay them anything. The other joke is if you call the private client they say on their website they offer a 24/7 service, and then you get an email back saying we will call within 24 hours. What an awful joke of a company. I can thoroughly recommend London Plumbers and heating Ltd (07475) 011972. They will always give you an excellent service. Regards Francis
