Certain channels stating no satellite signal, very intermittent

Almost certainly a dish misalignment. Although Sky themselves no longer support Sky+ and Sky+HD, if you have Sky Protect through Domestic and General Insurance you can call them otherwise you'll need to employ a local satellite engineer at your own expense to check it (or upgrade to Sky Q or change to Glass / Stream).
