London

Overview

London is the site of some of the best-documented modern examples of publicly funded infrastructure generating land value uplift that is mostly captured by private landowners rather than the public. A joint 2017 study by Transport for London (TfL) and the Greater London Authority (GLA), using Land Registry transaction data with local controls, found that the Jubilee Line Extension, the Docklands Light Railway (DLR) extension to Woolwich, and the upgrade of the North London Line into the Overground network produced land value uplifts of 52%, 23%, and 6% respectively, relative to comparable areas without the improvements.[1] A separate Nationwide analysis of mortgage data found a "transport premium" of up to 10.5% in property prices near London Underground and rail stations, rising with proximity to a station.[1]

Crossrail and Future Schemes

At the time of the 2017 report, Crossrail (the Elizabeth Line) was still under construction; the study found no clear residential land value uplift yet but did find commercial property uplifts of roughly 1–2.5% per year relative to controls, and a 50% increase in the density of new housing built within 500 metres of Crossrail stations compared with areas further away.[1] Looking forward, the same study estimated that a sample of eight prospective TfL projects — including Crossrail 2 and the Bakerloo Line extension, with a combined capital cost of roughly £36 billion — could generate around £87 billion in land value uplift, only a fraction of which existing UK tax and planning instruments (business rates, Stamp Duty Land Tax, the Community Infrastructure Levy) are designed to capture.[1]

The realized capture, as opposed to the estimated uplift, is documented in the CIB-commissioned Land Value Capture Study (Siemiatycki, Fagan & Arku 2023): of Crossrail's £18.8 billion cost, the Business Rate Supplement raised about £4.2 billion and the Community Infrastructure Levy roughly £300 million — a substantial but minority share of a project whose land-value uplift estimates run far higher, illustrating the gap between LVC's potential and its implemented yield.

An Illustrative Account

The report opens with a widely cited passage from property investor Don Riley, describing the effect of the Jubilee Line Extension on office properties he owned near two of its stations: "Those two stations raised the value of my properties by more than all the taxes that I had paid into the public's coffers over the previous 40 years."[1] The anecdote is offered by TfL/GLA as an illustration of the underlying pattern documented statistically elsewhere in the report, not as a rigorous measurement in itself.

Georgist Relevance

London's transit-driven land value uplifts are frequently cited in the Georgist and land value capture literature — including in Fred Harrison's Ricardo's Law, which uses a London home's house-price appreciation as a worked example of untaxed windfall gains (Ch. 1) — as a concrete, present-day illustration of the unearned increment that land value capture policies such as a betterment levy or land value tax aim to recover for the public that created it.
