I live in London too, but I really don't think this would work well for most things, Royal Mail, sure. But if I give a this to a private parcel company, theres no way they are going to figure out that, despite being the only #9 in my postcode, there are 3 streets that my postcode covers, google maps doesn't locate my house specicically if I put "9 <postcode>', it will absolutely be marked as could not locate.

I suspect there are databases that will geolocate such an address.

There are and they cost upwards of £20,000 a year for a license. There’s a reason why smaller delivery companies get the address wrong and that is probably part of the issue.

The official one provided by Royal Mail is called the Postcode Address File (PAF) [0].

That doesn’t provide any geolocation information (unless it’s changed recently?), for that you need OS AddressBase
