I had this ASHP installed in April. It failed the Trust Mark inspection because it was installed on uneven ground/edging and was not level front to back.

A man from the company has been out since and I believe he put a bit of broken up breeze block under one of the feet to level it out and put more soil on top.

The photos show the result.

For context the edging is concreted in, which is why they've just smashed it up and put feet on top. The soil area used to be a flower bed and To my knowledge no groundwork/weed membrane or anything was used. Just a little bit of new gravel was scattered around the condensation outlet (which had already frosted over with mineralisation, hopefully this is normal).

To be honest I was expecting they'd lay a concrete slab, but maybe I was expecting too much?

Anyway, I'm worried they're going to get me to sign to say I'm happy with it...and I don't think I am. Should I be? Is this normal/acceptable?

I also don't really understand why it's level in the middle (side to side) but not at the edges, I guess the unit must be bowed in the centre as the drip tray is not level.

I'm hoping trust mark come back out. Does anyone know if they do?

Thanks in advance for any advice.

Can you please post some photos? What you've described doesn't sound great.
