Had a biomass boiler fitted on a 7 year lease with original sales documents and contract states at the end of 7 years the lease would end and the boiler would be ours and our liability to service. Now dealing with another company, I think renowned for their terrible service. A shade greener, who are claiming they own the boiler and we must buy it from them, have it serviced to standards fit for installation, not maintenance and service, or pay them an extortionate amount for maintenance. Threatening legal action against and a court warrant to come and disconnect the boiler if we don’t comply. Anyone had any similar experience or have any advice on how to continue.
