Its not particularly onerous. But it does set a precedent for
retroactive building regulations which is slightly worrying.

There is no retroactive application of construction standards to
septic tanks.

Yes, there is.

The regulation says that by 2020 or if you sell the house you must
modify your private sewage plant to meet a given standard...

There is absolutely no requirement to modify existing plants. All
existing plants, no matter how old, can be left exactly as built. The
requirement is that you must ensure that the outflow from the plant does
not contaminate a waterway.
