post code searching

[Deleted User 234324]

Planning to implement a feature on our website (charity based organisation) to allow people to search for the nearest branch based on their postcode.

I've had a look around but postcode databases appear to cost an arm and a leg and its not something i could get funding for to buy! anyone know of a free UK postcode database available ?

preferably one with inner and outer postcodes ie XX1 1XX as apposed to just XX1.

cheers

Already used the google route could only find data based on the initial part of postcodes not the complete thing.

Reason is we have over a dozen branches in 3 towns, i'd like to implement a system where people can put their postcode into our website and get the nearest branch. Along with a map showing its exact location. Its possible with just the first part of a postcode but its not accurate as for example TQ1 covers a very large area in torquay.

I know that would be a lot easier to implement, but from a personal side I wanna do it just to see if I can, if you know what i mean.

The php/sql side wont be an issue but need the post code data to make it work properly as its something that could then be used by other branches in different counties.
