Mould on Ceilings Won't Go Away

Vents in Soffits are also recommended (1sq foot per 100 sq Feet of loft space is suggested)

This is obviously to reduce moisture in the loft space

I agree with almost everything you say here, but having had two oil-filled radiator's spring a leak, you either need to stand them on a tray or use one of these pipe-style low-voltage heaters that you see in greenhouses (we have several, including one screwed to a plank in our (old) motorhome to stop the upholstery and mattress feeling damp).

Absolutely, and a roof recover should come with the latest ventilation requirements.

GSOG has had a new roof, so I'm assuming the loft is ventilated thoroughly.

That leaves G's mould issue being down to either the loft-ceiling insulation not being taken to the ceiling edges, leaving cold strips when the mould is forming, or excess moisture production coupled with inadequate ventilation.

Almost always it's the latter.

Wow, you've been unlucky! Messy oil? We're you able to clean it up?

My suggestion for oil-filled types is just my personal preference, as I find they release heat more evenly, and they don't 'smell' - no burnt dust pong like you get on convector heaters.

It would be for an easy way to obtain the room-warming before bed and before wake-up. Alternatives are to turn on the CH rad manually at these times, and then off again to save energy, or to fit Smart TRVs. I have one of them on the main bedroom radiator - works a treat. But I also have an oil-filled on a digital timer as wife still complained...

These wee tubular heaters are ideal for areas that need a constant, but low-level, warmth, such as greenhouses, wardrobes suffering from damp, small box rooms, etc, but they are not going to perceptibly warm a bedroom just before bed and dawn.

I had the mould issues in my house, I bought Amy’s must haves mould treatment off Facebook, it gets rid of it but it does leave a shiny surface where it has been. I have decorated over it around 6 months ago and it hasn’t re appeared so far.

Sorry if stupid question - would I just measure my loft width x length in feet? If I take this measurement how do I then calculate how many total soffit vents I need?

Also would I then divide the total soft vent by 2, so I know how many I need for front and back of the house (its a middle terraced house)?

This is only a rough estimate - yes area is width times length and divide by two front and back

I have a couple of dehumidifiers that work well. Empty them of a couple of litres of water twice a week or so. Help dry the washing on a wet day.
