Apologies if this turns out to be a non-event, but my curiosity was raised by the fact that it carried out a pretty much straight in approach after it turned back (would there be issues about an overweight landing or would it have burnt off enough fuel) pitched against the fact that landing on 27R at LHR meant it overflew central London (which would suggest whatever was wrong was minor).

I'm afraid that given the location of Heathrow and the fact that westerly landing is "preferntial", just about any flight will fly over central London. What alternative is there?

westerly landing is "preferential"
Actually the A380 didn't overfly central London, just some expendable suburbs like Greenwich and Chiswick. And the landing track/height/speed looked entirely normal.

Anyone heard why it turned round?

Richard J.. Thanks for that. I'm a retired Heathrow Radar Controller and I think you'll find that a great number of Heathrow inbounds do overfly Central London on either a base leg or a closing heading for the ILS from the north.... keeping in mind that if one fell out of the sky a few miles either way wouldn't matter too much!

At night the preference direction alternates weekly (as opposed to daytime when it's always a westerly preference). It so happened that this week it's 27R/9L at night, with westerly preference.
"the runway to be used if weather conditions... ...preclude selection of the preferred runway".
I would reckon 90% of the time the surface wind would decide which landing direction to use - not some "political" choice.

But that nightime alternation programme is pretty meaningless as it also states:-
"the runway to be used if weather conditions... ...preclude selection of the preferred runway".

Heathrow noise: Home page and then click on 'Runway Alternation (PDF)' for this year's schedule or 'Noise Factsheets' for other information.
Runway alternation at night started in 1999, though the preference rules may have been revised more recently.
