Good examples of UK postcode lookup flow [closed]

Question

I'm looking for a good, well designed flow of a UK postcode lookup process as part of registration for an eCommerce account.

We're redesigning ours and want to see what is out there and how I can make it as friendly as possible.

--Update--

Basically our current design was a manual entry form (worked pretty well) which a less than experienced developer then bolted the postcode lookup onto.

So the order currently reads: Country, Line1, Line2, Line3, Town, County, Postcode. And he just put a lookup button on the bottom of that. So user goes line by line, THEN looks at postcode and uses the lookup.

I'd like to see some others in action because of the point made in the answers about allowing manual override.

Answer 1

Either way, please make sure you include a manual address override (ie allow the user to enter their address without the aid of a look-up). I live at a newly built address and it's not yet showing up on everyone's databases. I'm unable to register with eCommerce sites about 50% of the time. Very annoying.

Answer 2

What's wrong with the simple house number\name and postcode prompt?

Perhaps you could say how your current lookup works and why it's felt to need redesign.
