London housing targets need a better public dashboard, not another headline fight

By Eleanor Marsh

London housing targets are too often treated as a single scorecard: a borough is either “building enough” or “blocking homes”. That framing is convenient, but it hides the decisions that matter most for Londoners: where homes are expected to go, whether permissions are turning into completions, what type of housing is being delivered, and whether public transport, schools and open space can absorb growth.

The sharper problem is not that London lacks housing numbers. It has many. The London Plan sets strategic targets, City Hall monitors delivery, boroughs report planning pipelines, and central government publishes national supply statistics. The gap is that these sources answer different questions. A better public dashboard would make those differences visible instead of forcing residents, councillors and journalists to compare figures that were not designed to be interchangeable.

Why London housing targets matter

The adopted London Plan sets a ten-year London-wide target of 522,870 net additional homes for 2019/20 to 2028/29, annualised as 52,287 homes. It also distributes borough-level targets, which are meant to guide local plans and development management decisions. The plan is available from City Hall here: https://www.london.gov.uk/programmes-strategies/planning/london-plan/new-london-plan/london-plan-2021

Those figures matter because they sit behind many local arguments that appear, on the surface, to be about individual sites. A tower proposal near a station, a small-sites policy in an outer borough, a town-centre masterplan or an estate regeneration scheme may all be tested against strategic housing need as well as design, heritage, sunlight, transport and affordability policies.

For residents, the target is not just an abstract growth figure. It can affect the density of new neighbourhoods, the pressure to release industrial or public land, the scale of developer contributions, and the case for new transport capacity. For boroughs, missing delivery expectations can create planning risk, especially where local plans are out of date or where the Housing Delivery Test applies. The government’s Housing Delivery Test collection is here: https://www.gov.uk/government/collections/housing-delivery-test

What the sources show

The official record is best read as a set of layers, not one definitive number. City Hall’s London Plan Annual Monitoring Reports track performance against strategic policies. The Greater London Authority also publishes a housing completions dashboard on the London Datastore. Central government publishes net additional dwellings tables for England, including local authority-level data. These sources are useful, but they are not always measuring the same thing in the same way or on the same timetable.

The relevant official pages are City Hall’s Annual Monitoring Reports page, https://www.london.gov.uk/programmes-strategies/planning/implementing-london-plan/london-plan-annual-monitoring-reports, the London Datastore dashboard, https://data.london.gov.uk/dataset/housing-completions-dashboard, and the government’s live tables on net supply, https://www.gov.uk/government/statistical-data-sets/live-tables-on-net-supply-of-housing

The key distinction is between target, permission, start and completion. A borough can approve a large scheme that does not start for years. A developer can begin work but phase completions slowly. A site can deliver many homes but fewer affordable homes than residents expected after viability negotiations. A year of weak completions may reflect older planning decisions, finance conditions or construction capacity rather than only the current planning committee’s stance.

Competing readings

One reading is that London’s planning system is still too cautious. From this view, high land values, strong labour demand and acute overcrowding make the case for denser development around stations, more consistent small-site rules, faster local plan updates and fewer discretionary delays. Supporters of this interpretation often argue that the capital cannot meet housing need if every borough treats its target as an upper limit or if brownfield intensification is diluted site by site.

The opposing reading is not simply anti-housing. It argues that targets can become detached from delivery constraints. London relies heavily on complex brownfield sites, estate renewal, infrastructure coordination and private finance. Some boroughs also face difficult trade-offs between housing, industrial land, flood risk, heritage, tree cover and social infrastructure. In this view, a target that does not explain tenure, family-sized homes, build-out rates and infrastructure funding is a blunt instrument.

There is also a third, more practical reading: the target debate is being asked to do too much. A single annualised number cannot tell residents whether a development is well designed, whether a school place will be available, whether bus priority is funded, or whether affordable housing will be delivered early in the phasing. Those questions require project-level and borough-level evidence, not only strategic totals.

What remains unclear

The biggest uncertainty is not whether London needs more homes. The official policy framework and repeated monitoring exercises make clear that housing supply is a central planning concern. The uncertainty is how much of the shortfall, where it exists, should be attributed to planning decisions rather than interest rates, construction costs, landowner behaviour, infrastructure delays, affordable housing grant levels or market absorption.

Another unclear area is the public visibility of stalled permissions. Londoners can often see a planning approval in committee papers, but it is harder to follow whether the legal agreement has been signed, whether conditions have been discharged, whether construction has started, and why a site has paused. Without that chain, political arguments about “approved but not built” homes remain difficult to test.

Affordable housing reporting also needs careful reading. A headline completion total can rise while the tenure mix disappoints local need. Conversely, a scheme with a high affordable proportion may take longer if it depends on grant, land assembly or decanting arrangements. The public debate would be stronger if delivery dashboards made tenure, phasing and infrastructure dependencies easier to compare.

Practical checks

Readers assessing a local housing claim should start with five checks.

First, identify the benchmark. Is the claim referring to the London Plan target, a borough local plan target, the Housing Delivery Test, net additional dwellings, planning permissions, starts or completions?

Second, check the period. Annual figures can be volatile, especially where a few large schemes complete in one year. Ten-year targets should not be judged only from a single reporting year.

Third, separate homes from affordable homes. A scheme’s total units, affordable units, social rent-equivalent homes and intermediate products can tell very different stories.

Fourth, look for delivery blockers after permission. Committee approval is not the same as a completed home. Section 106 negotiations, reserved matters, financing, utilities, land assembly and construction phasing can all affect timing.

Fifth, compare official sources before drawing a conclusion. Use the London Plan for the policy target, City Hall monitoring for strategic performance, the London Datastore for mapped or borough-level completions, and government net supply tables for national statistical context.

London does not need fewer housing numbers. It needs a clearer public route through them. Until that exists, the safest way to read any claim about delivery is to ask which stage of the housing pipeline is being counted, which source is being used, and what the figure cannot show.
