I hope it is axed. I'm fairly sure it's a crappy way to promote green measures.

To the end of March 2015:

ECO - 1,430,054
Cashback - 15,696
GD Finance - 12,170
GDHIF - 21,964

Total 1,479,884

As some measures will have been financed through multiple schemes there is some double-counting in these figures. Measures installed under GD Finance are currently running at about 1,000 per month.

And if £ spent, are they £ claimed, or £ spent?

That's quite a lot - not bad for a half baked scheme - 5% of UK housing stock, isn't it?

I think an awful lot of those measure were of pretty marginal effectiveness mind you, and I seem to recall a high proportion of boiler replacements, which I'm not sure is a great use of funds. This is a lazy criticism though as I haven't had time to check!

Thanks Ted

If you follow the link to Monthly_GD_ECO_Tables_-_21_MAY_FINAL.xlsx and go to table 3b, it makes interesting reading on the number of Micro-generation installations.

I must admit I do get a bit confused will all the schemes available.
ECO, or in English, Energy Company Obligations, seems to be split, or take advantage of other schemes, such as:
Carbon Saving Target (CERO)
Carbon Savings Community (CSCO)
Affordable Warmth (HHCRO)

Then there is the total number of measures delivered by the Green Deal Home Improvement Fund, GDHIF, which I think is a free, or very low cost to the customer scheme. There where 22,239 of these.

There was also the cashback scheme, 15,696 where delivered, 12,379 where for new boilers. I am not sure if that was part of another scheme and a bit of double counting has taken place i.e. could you get GD finance and cash back.

The GD finance was 13,082, so a pretty small number really. Did the GD bank not have £2bn to lend out. A quick look at http://www.tgdfc.org/
shows that it is lending, or plans to lend £50m in May 2015. That is up from £9.9m a year ago.
As this is ongoing plans, I assume, without looking closer at the data, that if you divide 50,000,000 by 13,082 you get the mean value of each deal, £3822, or about the same as a 3 kWp PV system.
There were 3,755 PV systems installed under all the GD initiatives, but only 2,042 solid wall insulation installations.

I think the gas boiler installers are going to miss this scheme.

I have mixed view on gas. I would prefer we could reduce usage to the level that we can supply enough energy via wind, hydro and solar. But if we are going to burn things, then gas is best.
I think our new Energy Secretary has found this out (not that she will be there long as I think she is Pro EU).
