I am completely appalled once again by Swale Heating. My advice to any person considering using this company is please DO NOT USE SWALE HEATING. From the simple installation of a new boiler and radiators there has been nothing but incompetency from start to finish. And now in less than a year since installation my boiler is losing pressure, and I am now looking to replace the 3rd thermostat as I am told it could be a "bad batch" - completely and utterly unacceptable!!! On requesting a new thermostat to be fitted as still under guarantee and broken on two previous occasions (the last one only fitted 5 weeks ago) I specifically requested the engineer arrived with the part and of course on two occasions they didn't, I have now been told that the next available appointment is in January 2020. Added to which because the brand new boiler has been losing pressure since installation the Swale Heating Engineer requested a leak sealant be added without consulting me or having the courtesy to say that I would be charged for this and I have now been invoiced £91 for something I did not request. Swale Heating now tell me that they will not fit the 3rd faulty thermostat without me paying for the leak sealant that was ordered by their engineer without my consent. How is this company actually functioning? Ultimately I am now left still under guarantee with no functioning heating system and staff that do not communicate with each other. I will not accept somebody on the end of the phone (having waited in a queue once again for 50 minutes) saying sorry. This company need to be held responsible for the way they treat their customers.
