I am I scotland if that makes a difference we moved out and the buyer moved in on the same day. The day before we had the hot water on so I could clean etc. Today I received a letter stating the boiler isn't working so I contacted the buyer and want up to have a look. The boiler is switching on but cutting off. He told me it didn't have any pressure so they put it up. Now here's the part. I believe he didn't have it switched on properly and has went a nd fiddled with the pressure making it too high and thus breaking the boiler. I only know this can be done as I did it myself a few years ago. If this is the case and he has broken it are we still liable?
