UK Address Oddities!

House numbered -1
A few of my previous blog posts have been about quirks in the UK postal address system. As a result of these posts being moderately popular, people have contacted me to tell me about other such quirks. This pleases me greatly – I like quirks.

Mmmmm quirks.

Also, since finding the HM Land Registry property sales data, I’ve discovered some other vaguely interesting stuff, so I thought that I’d collate all this information into one big blog post of address-based quirky goodness.

I promise this will be the last address-related thing for a while. If I discover more quirks, I’ll just edit them into this post.

PS. If you’ve not read my previous posts, The HM Land Registry property sales data is a list of most residential property sales in England and Wales since 1995. It’s not a comprehensive list of every house in the UK, so the findings below are not comprehensive.


House Numbers

Highest House Number

In the HM Land Registry property sales data, the highest house number is 9156, which belongs to a house near Beccles in Suffolk. However there are no other houses on the same road, nor in fact anywhere nearby, which are numbered above 2000. I assume that, in the same way that you can give your house a name, you must also be able to give it a number as a name. There can’t be any other reason why a house on a street with fewer than 10 other houses would be number 9156. Or why a house in Owls Green, a village of about 20 houses near Ipswich, would be numbered 2820 (cute).

If we only include streets where the house numbers increment more or less continuously upwards, according to the HM Land Registry there are five streets in England and Wales with legitimate house numbers above 2000 (with the number of the highest house in brackets):

  • Bristol Road South, B45 9JL (2022)
  • Hessle Road, HU13 9NN (2063)
  • Warwick Road, B93 0EF (2111)
  • Coventry Road, B26 3PX (2599)
  • Stratford Road, B94 5NH (2679)

Four of these streets have Birmingham postcodes.

Anyway, it means that the highest numbered house is: 2679 Stratford Road, B94 5NH.


Lowest House Number

Yes, you heard me.

You might assume that the lowest house number would be 1, but there are quite a few houses numbered zero. Here are some (but probably not all) of them:

There are even some houses which go into negative numbers:

There’s a good chance, however, that the lowest house number is this:


Non-integer House Numbers

The usual thing to do if you’re putting a new house in between two existing houses with consecutive numbers, is to add a letter: 10a, 17b, etc. But there are a surprising number of houses with fractions in their house numbers.

Here are some of the “halfway” houses:

Other Fractions

Map showing house number 3.25

The two buildings marked with red arrows are shops, and according to their websites (here and here), they are both 3 Windsor Street, but it seems that officially one is 3½ and the other is 3¼.

Likewise, the house marked with the purple arrow has the name Windsor Cottage on its name plate, but again it seems that officially it is 1¼.

There’s also 1¼ Woodchurch Road, Camden, London.

And on the High Street, Earl Shilton, Leicestershire, there are five consecutive houses which are numbered: 75, 75a, 75b, 75½, 75¾


Weird Numbering Schemes

Tony pointed out that Nesta have a map on their contact page showing that they’re number 58 in a run of numbers, on London’s Victoria Embankment, which goes: 40, 58, 50, 56, 60.

Bryn notes that the High Street in Kingswinford is numbered by the distance from one end of the road in metres. They have still kept odd and even numbers on opposite sides of the road.


The widely stated ‘fact’ that all you need to provide is a house number and postcode for your post to reach the right address is not always true. There are many instances of different buildings having the same number and postcode. For example…

  • 1-4 Jubilee Cottages, Warwick Road, B94 6AZ and 1-4 Cedar Cottages, Warwick Road, B94 6AZ
  • 1-3 Weymouth Street, BA1 6AG and 1-3 Riverside Mews, Weymouth Street, BA1 6AG, and 1-3 Weymouth Court, Weymouth Street, BA1 6AG
  • 1 The Chase, HA5 5QP and 1 Rose Cottages, The Chase, HA5 5QP and 1 Park Cottages, The Chase, HA5 5QP and 1 Leamington Cottages, The Chase, HA5 5QP

Royal Mail Address Finder for postcode CV12 8UEThe postcode CV12 8UE seems to cover Gatehouse Lane, Emes Walk, Bucklers Yard, Homers Yard, Lye Corner, Sleets Yard, and Old Penns Yard – which all share house numbers in various combinations. This must be super confusing – I can’t work out where most of these are on a map!

They all appear in the Royal Mail’s address finder.

The postcode HD7 5UZ in Huddersfield also covers about seven different roads.


Street Names

Dual Named Streets

David pointed out that in Edinburgh there are streets such as Haddington Place/Elm Row, which have different names in opposite directions.

Those streets have a tiny barrier down the middle, making them dual carriageways, but Shay went one better with two streets in Gateshead where each side of a single-carriageway road has a different name. Cambridge Terrace/Oxford Terrace and Ashgrove Terrace/Richmond Terrace. The second of these has separate sets of numbers on each side of the street, so 1 Richmond Terrace faces 1 Ashgrove Terrace, on the same road. Some of the mapping sites struggle with this, just showing one of the names.

Anthony notes that the houses on the west side of Lainey’s Close, Marlborough SN8 1BS, actually have the address Chiminage Close, which is a road running to the north. On one map I found, and in fact in real life as well, it looks as if Chiminage Close extends round and becomes the pavement of Lainey’s Close!
Chiminage Close


Ralf points out a strange phenomenon in Stevenage where entire estates, including the main road and all the spur roads, share the same name. So there’s Wisden Road, Jessop Road, Archer Road, Ripon Road, and others.


Unimaginative Names

There are over 600 streets called The Street, and over 400 called New Street. There are almost 1000 roads called New Road, but oddly not a single road just called The Road.

In Cumbria there is a road simply called Street.

In Somerset there’s a road called Street Road! It goes to a town called Street.

There are almost 2500 streets called High Street, and many more which are <name of town> High Street, but there are only 59 streets named Low Street!

Lots of industrial estates don’t bother naming streets at all and just give them numbers instead. Sometimes this happens with housing estates as well, like this one in Grimsby, and this one in Hull.


Apparently, the shortest address in Royal Mail’s address database is:

Elba, Duns, TD11 3RY

The longest address in their database is actually on the Isle Of Man, so not actually in the UK. It’s a government department where two thirds of the address is just the name of the department and the building it’s in.


Celebrity Names

There are at least three celebrities who have been named after UK streets:


Single Word Roadnames

And finally, inspired by Paul’s comment, I took a list of single-word streetnames, and cross-referenced it with the SOWPODS Scrabble dictionary to find a list of street names which are real words. Here are just a few of the most random ones…

Fairyland, Chemistry, Tweed, Football, Solid, Dolphins, Goldilocks, Playground, Hobgoblin, Countryside, Dart, Badgers, Panorama, Antlers, Chapter, Dungeon, Loan, Bohemia, Flush, Groats, Hide, Jesters, Valentines, Drawback, Sixpence, Viking, Side, Paris, Equilibrium, Liberty, Tranquility, Butts, Butts, Butts, Bottoms, Bottoms, Sprays, Swallows, Butts.
