Just an update to this thread since I asked about others experiences etc.
I have now installed a Starlink system myself - I purchsaed the Standard Kit / Set up for £75 - it arrived within 10 days from the USA.
Due to the high winds we experience here, I just felt the wall mounted brackets they provide, didn't seem strong enough - to few points of contact for my liking. So I purchased a more robust one for £65 and fitted it to the chimney.
All set up and working and a much improved experience from the system which I had before - which was a SIM card relying on a mobile network coverage.
Using their App, the system is performing very well with 100 mbs being recorded - whatever that means😁
