Having searched the forums for where this might have been addressed, it seems to me that it has not. This may be due to the fact that the forums are heavily weighted towards the US.

I live and work in the UK and naturally collect points on my business trips by staying at Hilton properties. However I would like to know other ways of collecting points, which can be done as a UK resident. There seems to be a distinct lack of programs compared to the US. One program which we do not have but which would be fantastic is Hilton HHonors Dining. Anyone know when is this likely to be introduced over here!?

So here it is, the only ways that I know of to earn points in the UK. It is short. Please add to the list as you see fit:

1) Staying in Hilton properties.
2) Converting Amex points.
3) Hilton HHonors Visa Credit card
4) One-off bookings with car rental companies (Avis etc)
