We installed secondary glazing at the front and rear ground floor of our house while it was still single glazed - so 40 odd years ago. I retained the secondary glazing when the double glazing was fitted. It removes any real risk of condensation on the front window and patio door. It would still remain in place, even if I fitted triple glazed. Every little helps.
We get quite a few customers fitting our secondary glazing to their existing double glazing. We're up front about their not being the same impact as if applied to single glazing, but we get surprisingly good feedback.

Once you've done that basic hygiene factors of decent insulation/air tightness, further improvements are very expensive for very little gain. Often you'd be better to add a few more solar panels. Obviously you need the space to put the panels, but a typical 3/4-bed house with a roof designed with solar in mind can fit 6kwp on the South(ish) roof and another 6kWp on the North(ish) side. That'll be more cost effective than expensive marginal improvements to insulation!
Not so sure about that. In winter PV is not even enough to run the house wheras that is where insulation is at its best 24/7. I think you need both as the whole is better than the sum of the 2 parts, just like batts and PV
Possibly the cheapest way to create triple glazing if you already have double retro is to fix acrylic sheets with clear double sided tape. Probably best suited to North and East windows.

How does poly carbonate compare with acrylic for performance?

I suspect not much worse, as I believe that the surfaces of the layer have a major effect, hence clingfilm working quite well - and highly cost-effectively!

I made and stained a wooden frame with 2 layers of the film. I fitted a strip of foam draught excluder round the edge so I could push it into the window reveal of a non opening 1m square North facing double glazed window and easily remove after winter. The window was just behind my wife's right shoulder when she was watching TV and she could feel the cold air movement caused by the cooling effect of the glass. Immediately I fitted the extra 'glazing' she commented how much better it was and it is all but invisible. That was about 10 years ago it has only ever been removed to repaint walls.
