    i'm looking to do a bit of work to the house every year. Unfortunately we can't afford to do it all together. This year I was looking at installing a DCV system and possibly upgrading the windows. The DCV system will sort a condensation issue we've been having after insulating the attic.

    We're hopeful of adding an extension to the kitchen next year so i was thinking of upgrading most of the windows this year to keep things moving. I would leave the kitchen windows as is until next year when the extension is being done. The existing windows are PVC double glazed and probably 10-15 years old. Just wondering if it's worth doing them at all if they're 'grand'? Just wondering if anyone else replaced double glazed PVC windows recently and if it made much difference?

    if the windows are in good nick ,then the payback from DG to TG is prolly close to 75-100 years, depending on the now vs new U value

    Why not retro a full MHVR

    I wouldn't be able to get achieve the airtightness required to make MHVR efficient. I think you're right about the windows. I could probably spend the money on something more pressing!

    10-15year old upvc will ‘radiate cold’ in winter. Suggesting payback on a purely cost basis, I’m not sure I’d agree
