    This time last year I had a couple of threads about renovation works on a semi-detached rental property. Just reporting back.

    It was just the basics on the work. Total cost was perhaps ~4-5k.

    - IWI on nearly all the external walls (except for kitchen area) - 50mm celotex plus a vapour barrier.
    - New Grade A DG doors front and back.
    - Good loft insulation.
    - Ventilate by using PIV at top and trickle / boost HR an (Vent-Axia Lo Cardon Tempra) at bottom.
    - Replace bathroom fan with a model with a backdraft shutter.

    The existing boiler is OK but not super-efficient.

    The T, reports that the previous Ts had gas/elec bills running at £120 per month on standard tariff, and that:

    - Switching has knocked that down to about £85 per month ie approx £1000 a year
    - The works done appear provisionally to have knocked that down further to about £55-60 per month, based on the results from October being £36 + a crude extrapolation.

    Clearly I need to ask T to get some readings over the winter, but a very modest success so far.

    In the previous smaller semi detached terraced house ie 2 beds, the T was paying energy bills of around £180-£200 a month, and the landlord was eventually enforced on for that property by the Council as 'unfit for human habitation'. That is criminal, and a good example of what Council need to do. LL ended up selling it to pay for improving other properties. T still trying to extract money owed from previous LL, but at this point is about £1k a year better off on property costs in a 3 bed vs 2 bed.

    The EPC gain was minor - 54 to 58 though that is Band E to Band D. Further steps will involve a kitchen refit, new boiler or raised d/s floors - not minor.

    About ventilation

    and a much more detailed one with target numbers that I cannot find !

    Just goes to show that it need not costs a fortune, or need technology to get good improvements.

    No criticism intended, but I do wih people could quote kWh rather than price. I am sure I could easily double the price I pay but use no more energy (just switch off the night storage and run at 24p/kWh).
