I am in the process of getting quotes for replacing my old back boiler with a combi boiler and the first heating engineer to call has said that I will need to convert my existing single pipe system to a dual pipe system! Is that correct? No combi boilers will work with a single pipe system!

Fitting new combi boiler using existing single pipe system

Some manufacturers explicitly forbid it, nobody recommends it. If you system's that old you probably have rads which are due for replacement? TRVs are a problem too.
Converting to 2 pipe is not that hard when you look into it, and well worth it.
