He gave me the options of I either dig it up and sort it or they can do a CCTV survey for £200 - that was the only option. I declined and he didn't try to offer a cheaper alternative.
£200 could be money well spent if ultimately the pressure jetting fails, or the blockage gets more often/worse, because the jetting is actually dislodging small pieces/sections of the pipework.
Should have asked how much for cash and no paperwork.
I have not come across a tradesman who will discount for cash for years. They always quote the taxman. In the 70's it was par for the course for the tradesman to suggest cash as a cheaper option.
