They replaced my boiler under the insurance in March 2018. The fitting was shoddy and the boiler did not work, but left extension leads over my ten year old bedroom into the loft for a weekend, while they arranged an electrician. They snapped off radiator valves, and issued court proceedings against me for non payment of the balance owed, even though the heating and hot water system was not working.
After over twenty visits by different plumbers (never the same one) over a period of two years, they sort of got it working. However when I had the boiler serviced the following year, the magnetic filter was completely blocked as they had not put any rust inhibitor in the system.
They referred me to the Financial Ombudsman Service, knowing they could and would not adjudicate on such a case, wasting more of my time.
They are not signed up to “Disputes Resolution Ombudsman”; you have to ask yourself why?
So Homeserve referred me to ADR Group www.consumer –disputes.co.uk and after liaising with them Homeserve disingenuously confirmed that “Thank you for confirming. I can confirm that we do not consent to your service reviewing this complaint.” As they obviously knew that Homeserve was in the wrong.
I wrote to Mr Richard Harpin their chief executive, who did not even bother the reply, and my only course of action is to take them to court to get back all the time I had to take off work waiting for their engineers to arrive, time and time again. Defending their legal action against me, for so called none payment of the completion balance, even though the boiler they had supplied was not working properly. Along with the reams of correspondence trying to get them to fix the system.
As a footnote: They supplied the boiler under the insurance I had, but for the shoddy fitting they charged me more than the boiler and fitting would have cost from another company.
Please do not waste your life arguing with this disingenuous company. Just avoid.

Ben, Homeserve have refused to let any independent party review your decision, because you are not confident of it. Homeserve will not even sign up to the “Disputes Resolution Ombudsman”, and your company refused to let ADR Group review my complaint. WHY DO YOU THINK THAT WAS? Because you are not confident of the ridiculous decision making in HOMESERVE, liking taking me to court for the balance of my boiler fitting, when it did not even work!.
