I can get insulation for about £10 a roll at B&Q. Why would I use you?
You can go to any DIY store and buy insulation to do it yourself. In fact many people do just that. However, it's a dusty job - you'll be poking around in your loft space where there's a lot of accumulated dust, insects, cobwebs etc. The mineral fibres will get on your clothes and into your skin - you'll itch like crazy for about a day. If you are really unlucky then you might develop an allergy.
If you only have a small car then you'll be limited by how many rolls you can buy at a time. This means you might be tempted to skimp on how much insulation you buy and end up with inadequate thickness - false economy.
We purchase bulk insulation and pass on any savings to you. Our whole business is about offering an efficient, value-for-money service to our customers.
B&Q and Tesco are offering deals for £198 for a complete house. Why not go that route?
The simple answer is that you can. If you are driven purely by cost then this may be a sensible option. The downsides are that you may have to wait several months for your insulation to be installed - during which you've paid for the cost up front. You'll be rueing the day when a cold January blast of Artic weather puts a chill through your bedroom ... and you still haven't got that insulation.
