The Zone1 (45cm) dish if properly installed is more than capable of recieving the much stronger signals from 28.2 (compared to the older 19.2 birds) and should provide a signal in all but the worse weather.
If you live in a northern or western location then a Zone2 (60cm) dish may offer more protection as most transponder footprints weaken as they travel in the NW direction but the 28.2 slot again is more UK friendly than the older analogue birds.
If you have problems with the signal now then you should get the dish checked as well as the LNB and cabling, if the dish is performing as designed then a simple SKY+ swap with the SKY+ HD should be fine.
