No, the Postcode Address File should not cost £487m

In 2021 the UK government’s Geospatial Commission prepared a briefing paper for some discussions about address data. It has been released to the journalist James O’Malley after a freedom of information request.

The paper was prepared in response to the long-running campaign asking the government to deliver on political commitments to make the list of UK addresses – and other non-personal geospatial data – freely available. People could then use the data to improve public services or build innovative new businesses.

The paper includes the mind-boggling statement that a government project in 2016 estimated that the cost to the UK government of buying back UK address data from the Royal Mail would be £487m. 

Yes, you read that right. That figure was four hundred and eighty seven million pounds.

I made this very amusing image using a highly sophisticated meme generator

It’s a big number and – if true – one that would call into question the whole campaign.

But, it doesn’t hold up to critical scrutiny and, unfortunately, the 2021 paper repeats this estimate without questioning it.

The civil service needs to be less credulous when it comes to claims over the financial value of data assets, and the UK government needs some fresh analysis.

Valuing intangible assets is difficult, valuing a commercial product is much easier

Valuing intangible assets, like data, is difficult. I’m such a fun person that I read books and academic papers about the different ways it can be done.

But, to the Royal Mail address data is fundamentally a commercial product line. Or, to put it another way, a small business within their larger business. 

At the simplest level the product is created when Royal Mail adds postcodes to the addresses created by local authorities. The Royal Mail then sells the resulting data product – under a commercial licence – both back to the government and onto other businesses.

This product is regulated. Every year it brings in about £30m of revenue and generates about £3m in profit.

A valuation of £487 does not pass the ‘smell test’

A price of £487m values that product line at a multiple of 162 (one hundred and sixty two) times its yearly profit of £3m.

If the valuation is true then that single product line would account for 15% (fifteen percent) of the current market capitalisation of the Royal Mail’s owner, IDS (International Distribution Services).

To put that further into perspective the whole of the IDS business has a turnover of £12bn. 400 (four hundred) times the turnover of this product line of address data. Yet somehow this small product line is 15% of the market capitalisation?

The IDS annual financial report does not even mention address data. It is too small a part of their overall business.

The valuation discussed by the UK government’s Geospatial Commission in their paper makes no sense. It does not pass the smell test.

We can imagine some negotiations

But, let’s look deeper. I can imagine the Royal Mail’s negotiators asking for such a large figure from the government. Why wouldn’t you try?

The Royal Mail might have talked about the economic value that better and more accessible address data could create for the UK economy. They might be thinking that they hold a unique asset and have the UK government over a metaphorical barrel. They might have argued that the £3m a year in profit was necessary for the financial viability of the Royal Mail. The negotiators might have said that only the Royal Mail can create addresses that work for deliveries around the country and that it was a vital part of delivering the UK’s universal postal service.

This is what OpenAI’s DALL-E thinks tough business negotiations would look like. So tough that there’s not even a packet of biscuits on the table.

But the argument in return is that most of the effort that goes into creating address data comes from local government officials around the country. That if the address data they create is good enough for other services and other delivery firms then it can be good enough for the Royal Mail too. And, most importantly, the small amount of financial value that this product line creates for the Royal Mail’s own business.

But the negotiations should have simply started with a fair market value

But, to draw a comparison to the physical world, this type of negotiation would also have been the wrong starting point.

If the government needed to compulsorily purchase a piece of land or a business to build some physical infrastructure the discussion starts at the market value that a willing seller might find on the open market. The buyer selling a piece of land does not get to claim a percentage of the larger economic value that the new infrastructure could create for society. They simply get to sell their asset at a fair price.

The negotiations for selling the Postcode Address File back into the public sector should have started the same way. This would have cut through the complexity of data valuation.

No other buyer would pay £487m for a regulated product that creates £3m in profit a year, a multiple of 162. It is not the market value.

UK government and Royal Mail need to be realistic about the market value of address data

The campaign to open up UK address data is supported across the political spectrum. Most recently it was supported by peers from four political parties – Labour, Conservatives, Greens and Liberal Democrats.

A Minister from the previous government rejected their request and referenced this flawed report from 2016 that includes this unrealistic figure of £487m. The Minister should have asked the civil servants to start again.

The new UK government is building a digital centre for government and plans to create a National Data Library to deliver better services to people, researchers and businesses. That National Data Library could create significant economic and social value for the UK, particularly if it opens up foundational datasets, such as geospatial data. Other countries are doing this and the UK is falling behind.

As part of that work the Ministers from the new Labour government should ask their officials to stop relying on their flawed, old work and carry out a fresh analysis of address data.

Two events on different types of ‘public good’

‘Public good’ is a term that is frequently used in debates about data, statistics and AI. It has featured prominently in UK government policy and strategy, but the term isn’t always well defined or explored.

But in the UK it can seem like there is little recognition that there are different uses of the term ‘public good’ in debates elsewhere in the world, particularly with the emergence of the concept of ‘digital public good’. Sadly UK policy seems to have gradually become more insular over the last decade as the country has wrangled with the results of the Brexit referendum and a seemingly never-ending carousel of ministers with responsibility for this area.

The UK’s new Labour government’s draft industrial strategy, published in 2022, said that “our second mission will be to harness data for the public good“. It has created a new “digital centre” within DSIT and plans to build a National Data Library.

It seemed a good time to explore the concept of ‘public good’ a bit more., soJob de Roij and I from the RSS’s Data Ethics and Governance section have organised a couple of online events with speakers with expertise in both the UK and more globally.

Both events are free for RSS members, and £10 for non-members.

Read on for more about the two events, the confirmed speakers, and some background reading on the topic.

Event 1: For the public good

The UK Statistics Authority’s Five Year Strategy 2020-2025 is called Statistics for the public good. It also features in Labour’s draft industry strategy.

While some work has been undertaken to unpick this term by understanding how the UK public think of it, and to review how the public good can be enhanced to support policy makers, regulators and practitioners, there is more work to be done to ensure that statistics and statistical processes truly serve the good of the UK public.

Speakers

Starting questions

What do we mean by “serving the public good”? What are the gaps in our understanding of how to make things serve the public good? How do we fill those gaps?

Event 2: As a public good

Meanwhile there is growing attention around the world to the concept of ‘digital public goods’.

The UN defines digital public goods as “solutions and systems that enable the effective provision of essential society-wide functions and services in the public and private sectors”.

Identity assurance and payment systems are well-known examples of digital public goods. Certificate transparency, which underpins website security, a less well-known example.

In the world of statistics things like national statistics or the new ONS Integrated Data Service could be grouped into the concept of digital public goods. But what other kinds of digital public goods might, or should, exist that are relevant to statisticians? 

Speakers

Starting questions

What is a digital public good? When is data, AI and statistics a public good, and when is it not? Are any digital public goods that could help statisticians serve the public good missing? How do we build and govern digital public goods?
