Over the weekend I did some more problem-solving and it does appear that the issue is the mains wiring and particularly when using the adapters to link the top and middle floors. I've since linked my important PC to the router with a long Ethernet cable (which I was trying to avoid) and this gives me a wonderful 75Mb download speed.
My advice to anyone else considering using Powerline adapters with faster broadband (e.g. as is now possible with BT Infinity) is that you could well be disappointed at the speeds you get - it appears to be highly dependent upon your mains circuits. I've not been able to find any info about what can be done to a mains supply to limit the problems.
I've also been very diappointed at the technical support offered by e.g. Devolo who were only interested in defending their products (& this was having to use an international support phone number). I would advise them that they ought to start helping customers to solve the problemns as, with increasing broadband speeds, the flaws in their products are going to be increasingly noticed.

Indeed so, but some core advice would be very helpful e.g. can anything be done about it - if so what? ... and what steer can be given to a qualified electrician. At least then I would know whether to attempt to invest in trying to get a solution. SUch information would also be extremely useful to potential purchases as there will be a lot of people who will buy these products and, like myself, be disappointed.

I have exactly the same issue and I know it's not my main wiring. Develo's network dashboard is showing 100Mb+ between Powerline adaptors. When I speedtest through Wireless I get 77/16 when I connect directly to the Home Hub 3.0 I also get 77/16. When connected using Devolo#s 200Mb devices it nearly halves the download speed.
I reckon its QOS in the powerline adaptors doing it. I will call Devolo on Monday and raise a ticket.
