Government Grants loft and wall insulation

[Wings]

With several energy utility companies, offering government grants on both loft and wall insulation, I have just had a site survey carried out to see if both the property needs loft insulation, and if the wall insulation can be carried out.

The loft needs further insulation of 30 x 200mm rolls, and after deduction of the grant, I need to pay 500.00. Wall insulation can be carried out, and again after deducting the grant, my costs will be 900.00.

Seems rather expensive even after deducting the grants, and whilst I can both purchase and install the loft insulation, can one purchase and install wall insulation, and are there any pitfalls in carrying the works oneself.

I think they drill holes in the walls and blow little balls of insulation into the cavity, I doubt you will be able to do that yourself

www.diy.com et al - plenty of deals on insulation. Okay you have to do it yourself, but the savings can be colossal.

That sounds rather a lot of cash for a grant aided install.

There is no worse job than laying quilt in a loft space .

That much is certainly true! Still, we bought some ridiculous number of rolls from B&Q or homebase or some such for an absolute pittance. Buy one get two free or the like.

Sounds very expensive. I had 4 bed detached cavity walls done for around £200 by my energy company. Also got the loft insulation dead cheap from DIY store as others said and did it myself in a couple of hours. My loft insulation is now about 18 inches deep!

How big is your house? We had our place done with loft insulation (didn't need cavity) for £99 after the gvt grant in March this year. That was for 20 rolls laid to 200mm thickness.

I was going to start a thread asking about cheap loft insulation, looks like I've found what I need! Only £6 a roll, bargain. Will be topping up my existing over some bedrooms.

To the OP, I had my cavity walls done a few years back for about £150 IIRC. It was done via a British Gas deal. The prices you've been quoted are way OTT, unless you live in a mansion?

It was through British Gas that i went, my loft space that i have just measured is approx. 150 sq metres. I was told i needed 30 rolls of 200mm loft insulation, from the prices on offer at B&Q, cheaper to install oneself.

If only i can find a cheaper price for the wall insulation.

I did my loft last year with stuff from B+Q, they were doing some silly deal like 3 for 1 and I used the 200mm rolls that are wrapped in foil so dead easy to lay and fit on top of my existing insulation. I cost me about £60 to do an 80s 3 bed detached. I had the walls done under the BG scheme the year before and it was just under £200 with subsidies and a £50 rebate from my council tax.

I must say, it has made a huge difference to the house - the boiler used to be on and off all night before and now it hardly comes on at all during the winter evenings.

We had our walls and loft done about 6 months ago be The Mark Group. £300 all in. Did a good job too.

Beware cavity bridging with blown in systems. Cavities are there for a reason.

B&Q have presently on offer three 3.3 sq. metre 200mm rolls for the price of One, being 3.00 for 3.

Not really, roof floor space 150 sq. metres.

I paid £49 last year for our loft, 4 bedroom house.
I used

Is there such thing as too much loft insulation?

I was just wondering that! It is probably a law of diminishing returns but another 200mm on top for £25 can't be a bad thing...can it?
