If only there was a way to give minus reviews. I've been with Corgi since Feb 2020 and pay for the top level of support offering. I've experienced 2 issues with my boiler and believe they are linked. I've had several engineers in recent days/weeks and they are unable to resolve the issue. Apparently the free service I receive once a year was not carried out safely either. I have a Baxi DuoTech just over 4yrs old and therefore a popular boiler with parts readily available. I've had nothing but failed promises of calls and visits for one reason or another. Please please avoid and go with someone reputable.
