Heating and hot water at last!

My heating and hot water have been intermittent for the last couple of months, due to a badly installed unvented water tank. Thankfully, today everything was put right. Shame the only way to get that done was to send a solicitor's letter to the company which installed it... threatening to sue for breach of contract. The windows in the gable ends up in the loft still need to be sealed, so for now the legal action continues...
