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
