It's all estimated though and usually the savings over estimated. If the boiler only saves them ÂŁ10 a month the finance doesn't adjust to suit, and that's the problem. I'm not going to get myself involved in any potential for miss-selling which I can see happening in some cases.
I could sell any finace package in the same way, ie subtract projected savings from payment, the only difference with Green Deal is that it is attached to the property, not the individual.
The complexity ( most people you speak to even in the industry don't know the difference between a GD loan, GDHIF and ECO) and money the GDP loads on the plan is what kills the scheme for most, the idea is actually quite good. That's why the GDHIF and green deal works but makes the scheme uneconomic, the voucher pays off the excess the GDP adds on. The installer, as usual, gets no real benefit.
If the volume was there it wouldn't be so bad, but the uptake figures are disappointing because most can go to help link or similar and get a better deal, albeit as a personal loan.
I'll PM you the GDP's I'm involved with now. I wish I could see a way to work with it, as said if you can help the great. I've invested in it but as of yet can't see a benefit in keeping it up other than the odd ECO job we get out of it.
