Chapter 12 Monitoring


  1. The implementation of the London Plan will be kept under review using, in particular, the Key Performance Indicators set out in Table 12.1 and reported in the Annual Monitoring Report.

It is important to have a succinct set of Key Performance Indicators (KPIs) and measures against which to monitor the successful implementation of this Plan’s policies. The KPIs support key Mayoral commitments and priorities in a structured way. They seek to assess yearly progress and to build meaningful time series over time. The measure for each indicator shows the direction and scale of change that the London Plan policies are seeking to achieve. They do not themselves represent additional policy.

Performance against the KPIs will be reported in the statutory Annual Monitoring Report (AMR) to be published by the Mayor each Spring. The KPI figures will be accompanied by commentary that may also include additional corresponding performance figures. The AMR also monitors a range of other data beyond the new set of fewer, more strategic KPIs, compared to the previous Plan.

Table 12.1 - Key Performance Indicators and Measures

KPISupply of new homes
MeasureIncrease in the supply of new homes over the period (monitored against housing completions and the net pipeline of approved homes), towards meeting the 66,000 net additional homes needed each year up to 2030.
KPISupply of affordable homes
MeasurePositive trend in percentage of planning approvals for housing that are affordable housing (based on a rolling average).
KPISupply of office capacity
MeasurePipeline of planning permissions for office floorspace is at least three times the average office floorspace construction started over the previous three years.
KPIProvision of affordable workspace
MeasurePositive trend in affordable B1 workspace as a share of total B1 floorspace in planning approvals (based on a rolling average).
KPIAvailability of industrial land
MeasureNo overall net loss of industrial and warehousing floorspace in London (B1c, B2 and B8) in designated industrial locations (based on a rolling average).
KPIProtection of Green Belt and Metropolitan Open Land
MeasureHarm to the Green Belt and Metropolitan Open Land prevented through the referred application process.
KPICarbon emissions through new development
MeasureAverage on-site carbon emission reductions of at least 35% compared to Building Regulations 2013 for approved referable development applications.
KPIModal share
MeasureIncreasing mode share for walking, cycling and public transport (excluding taxis) towards the target of 80% by 2041.
KPILondoners engaging in active travel
MeasurePositive trend in provision of cycle parking (based on a rolling average) to support the target of all Londoners doing two ten-minute periods of active travel a day by 2041.
Air Quality
KPIAir quality
MeasurePositive trend in approved referable development applications demonstrating that they meet at least air quality neutral standard for emissions (based on a rolling average).
KPIImpact of development on London’s heritage
MeasurePositive trend in the reduction of harm and/or an increase in benefits to designated heritage assets in approved referable development applications (based on a rolling average).
KPIProvision of cultural infrastructure
MeasureNo net loss of culture venues and facilities* (based on a rolling average).

A comprehensive set of complementary and more detailed data and performance measures sits alongside the KPIs in the AMR. Some of the KPIs from the previous Plan are included and those time series are therefore retained. Specific other policy areas that are not covered by KPIs but where measuring trends – in particular on monitoring key planning-related social issues - is important include:

  • delivery of homes and jobs in Opportunity Areas
  • delivery of primary healthcare floorspace
  • provision of school places
  • delivery of floorspace for childcare facilities
  • provision of sports facilities
  • reduction of London’s digital ‘Not Spots’
  • change in overall green cover
  • delivery of sustainable drainage.

A new set of indicators measuring the performance of referable planning applications in terms of compliance with important policy issues is also being investigated. This could include for example if a design review has been carried out. The performance of referable schemes represents the most direct measure of the performance of the Plan.

The AMR is not the only tool to monitor London’s performance. It is complemented by other thematic reports including, for example, the Energy Monitoring Report and TfL’s Travel in London Report. Their indicators do not need to be duplicated in the AMR.
