I'd love to name and shame, just hope the central heating peeps don't post on here!!!
Well just who are they and whats their CORGI number?
Please put a little credibility into your story!
Its just possible from whats been said so far that you may be tenants from hell who are just out to make some money by pretending that all these things have happened! Are you now witholding rent? Thats a favourite tenants action!
I like to have a balanced view. So far we only have your side of the story posted without identifying yourself and from "somewhere" in the UK !!!
You can contact CORGI and ask if a boiler at the address has been notified to them. If not then give CORGI the name of the Agent and they will follow up the possibly unauthorised installer.
If you wont follow these things up then there is not point in bleating about it.
