Review by Joanne King
on 16th April 2026
"This is the third job Mark from Origin heating has completed for us . After the first job I did not hesitate to ask Mark to do further work for us . He has serviced our boiler and given our heating a complete overhaul. The second job I asked him to do was to fit a hive thermostat and remove the gas supply to a cooker that was no longer required . His last job was to remove a radiator, he cleaned the header tank and supplied and fitted a new pump as the old one had failed . Mark was punctual , courteous, explained what each job involved , sent a written quotation before each job. I have already ask Mark to do further work that we require and would highly recommend him."

"He installed a boiler for me about a year ago, and has come back this year to service it. He is so clean and tidy, and very efficient and thorough with his work. I have had no problems with him, and am very pleased with job he has done. I would absolutely recommend him, and have already done so to friends and family who are now going to use his services too."
