They were really quick at getting back to us, they were able to come the next day and attended exactly when they said they would. They gave us plenty of information throughout the process so we knew what was happening. They had the new inlet valve with them, so were able to do the job there and then. They took less than 2 hours, were polite and couteous throughout and have done a really good job on the cistern, it's much more efficient than it was before it broke.
