Aye. I built a shed last year with CCAGS support and have received the grant.
I did some drainage earlier this year which was approved for grant assistance, due to me taking so long to fill out the claim form I am still waiting for any payment.
I have also just been approved for support with woodland creation through the SGRPID RP scheme which is nothing to do with CCAGS but gives a comparison.
CCAGS is much, much, much more straight forward than the RP scheme.
The applications are fairly straight forward. The thing that I took a while to get my head around is that you have to quantify the benefit that what you are applying for will bring to the croft.
Saying "a shed will allow me to store feed" is not specific enough and does not quantify the benefit, you have to say "a shed will allow me to buy chicken food in bulk. I use 80sxs a year, costing £10 each (total £800). If I buy in bulk (at £7 each so total £560) the shed will save me £240 per year.
It requires a bit more imagination to quantify in numbers how a drainage ditch will benefit the croft.
From submitting your application it should take a couple of months to approve but my shed took a lot longer for various reasons. I think they aim to pay in about 6 weeks from the claim.
When submitting the claim I have taken it into the office in Inverness as they will check it at the time to ensure you have included everything needed and that your receipts are in the correct format (a big thing for them). But then I live close to Inverness - I suspect that if you live in Skye then it is not worth coming in just for that.
Let me know if there are any specific things I can help with (remembering that I am an very amateur crofter)
