@JohnMo - I missed your post! I'm going to get stuck into that now, thanks very much

That's great to hear @joe90. I've read a few more posts on this forum and seems like there's a wealth of experience. I'll no doubt tap into it in the coming weeks so that I can progress this

Thanks guys. Yes, and have some support. My father-in-law is a retired gas engineer, and I have a couple of friends that are qualified electricians. I have good confidence that together we could do what's required to install (though I've yet to design a solution) I hoped that was the case, but some of the content I've read recently, muddied the water. I know there won't be any grants via the DIY route, but so far, the cost after the £5k BUS payment is likely more than doing it myself. I say likely, as I've not designed and priced it yet.. Now that I know that it's a possibility, that's the next step. I'll take a look for schematics etc next to come up with options. Any worthy resources or pointers that anyone can suggest would be greatly appreciated.

Hello I'm interested in installing an ASHP, but quotes from businesses have been very high (£11k to £17k). Ideally I'd like to save money in the long term by switching, so using an installer seems out of the question. I am now considering a DIY install but am not sure if I can. What I wanted to clarify is: Does a heat pump need to be installed and/or commissioned by someone with an accreditation of some kind, or can I do it all myself?
