Hi Sam, We have just carried out some remote usability testing on this issue. Postcode lookup only seams to work in the UK, and the Netherlands for starters.
You need to ask for House Number or Name to reduce the number on the list of returned houses. Most people are used to enter their address so that they are very fast at it. We found that people could enter their address faster than the system would come back to them with the correct information. Most participants found the process frustrating. The system actually confuses people as it only asks them to enter a house number, and a postcode, when they want to type the full street address. I.e. if the address was 23 anywhere avenue. People often typed the full street in anyway. The system has to take a long field anyway as houses can have names as well as numbers. Form validation is a nightmare as houses in the UK, can have names, as well as numbers. The one point going for it is Address Validation, but then often there a time lag on the system been updated with the correct information, and therefore this even leads to issues.
