Cavity Wall insulation Installers

[Grumpycatsmum]

Has anyone had cavity wall insulation done in Scotland? We are looking to get it done but mainly because it's a condition of Scottish Government funding for a heat pump. I've had a real problem find a reliable installer and who will actually tell me if my house is suitable for it. I'm quite worried as it's near coast and west facing, and have seen some horror stories about in fill causing damp.

Anyone had a positive experience or can recommend a company??

Thanks

Bumping.

I know this is probably the dullest thread on here but does anyone have any experience? Anyone at all???

I've had some removed! It's not suitable for 1960s/70s timber framed bungalows...

That's a bit worrying @Superjaggy. Ours is 1970s bungalow! Although not sure if timber framed. Can I ask what problems you had?

We've had it for over 10 years and no problems, house built 1950.
It's made quite a difference heat wise to the downstairs, not so sure much difference upstairs.
1st couple of years we were in our house we had gas fire on in sitting room every evening in winter. Then we got cavity wall insulation and never had it on since!

Sorry don't have any details of company who did it now but we got Gov grant towards it iirc

Everwarm did mine (lothians) and I was very happy with it. Huge difference!

It was picked up in a home report survey when we sold it - around 3 years ago. Previous owners had installed it and the regulations must have changed while we owned it. Cost around £3k to remove becsuse the house was unmortgageable otherwise!

I'd be very careful. Also I would only consider a heat pump if no gas unless you are comfortable paying a premium to be green. Electric is much more expensive than gas even with a heat pump and insulation.

My house is sandstone so not suitable for CWI..What area are you in - moat of our friends are in the building trade one way or another so I can ask around.

Thanks @Kshhuxnxk. If you know of anyone that can be trusted that would be really helpful. We are near Helensburgh.

@Superjaggy. That's a new one on me. Hadn't realised it could affect mortgages.

@Blabla2 - I've looked at numbers quite closely and I don't think it's going to be much more than gas. Our current boiler looks like it's going to pack up soon and I really can't reconcile getting a new gas boiler given the climate crisis. I am worried about making my house damp though if I have CWI

It came as a nasty shock to us too @Grumpy - it's because it can form a bridge between the inner and outer walls and draw in damp.

I hope your house turns out to be suitable and I think you're right to move away from gas boilers - we're all going to have to do that eventually!

I have electric wet central heating which is more expensive than a heat pump but I do worry when I see folk taking out gas to put in a heat pump. Electric is very expensive. I have looked at cwi but like you worry about damp. There are some interesting articles on line about retrofitting insulation and damp. I think the green heating technology needs to improve and come up with more viable alternatives to gas. Money supermarket forum has some good posts.

Thanks @Butterflymosaic I haven't tried Everwarm. Will give them a call.

I have say @Blabla2 I worry about it too. I've looked at other options but most aren't that suitable. I'm hoping to put some solar in to support the pump but it's ridiculous really that we are having to try and navigate this all as individuals. It's a minefield

Totally agree. I would like to insulate, put in solar panels, batteries and a heat pump but the prices are incredible and no straight answers! So I am waiting hoping it will become clearer and cheaper!

I used to work for a CWI who did the beads and it seems a good product, non toxic that is easily removed. I got it and it's done a good job for my home.

Make sure whoever you go with is PAS2030 certified and the work is CIGA guaranteed.

There are LOTS of cowboys so research carefully and ask who has local authority contracts as they will likely be properly certified and care about their reputations.

Thanks. Unfortunately I've come across a few cowboys already. And some pretty unpleasant hard sell techniques too. I called Everwarm and they are going to give me a quote.
