Last updated September 15, 2026 · National screening observation from the [World Bank ICP 2021 API](https://api.worldbank.org/v2/sources/90/country/CAN/classification/PX.WL/series/1501200/time/YR2021/data?format=json) and [ICP data documentation](https://www.worldbank.org/en/programs/icp/data); locality and population from the [GeoNames CA dump](https://download.geonames.org/export/dump/CA.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 6058560). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Direct answer

For early office construction cost planning in London, the World Bank ICP reports a 2021 Canada construction price-level index of 217.0, with the world equal to 100. This is a national comparison—not a London CAD/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Canada in 2021; it does not measure a London market basket or current office tenders. GeoNames 6058560 records the locality at 42.9834, -81.2330, with snapshot population 422,324. That ranks London 15 of 50 listed places, while Kitchener is the nearest listed peer at about 76 km. Use these facts only to plan the comparable search. Obtain current local rates on a consistent area basis, then reconcile scope, taxes, fees, contingency and escalation. Retain the source, base date and reviewer when local evidence replaces the screening ratio.

What does the 217.0 construction index mean?

The World Bank ICP 2021 construction PLI for Canada is 217.0, compared with a world benchmark of 100. It is a national spatial price comparison assembled for the 2021 reference year. It does not say that office work in London costs 2.170 times a current world rate.

Which London inputs are known?

The reproducible locality point is 42.9834, -81.2330 (GeoNames 6058560). Its snapshot population is 422,324, ranked 15 of 50 listed places; GeoNames classifies it as a populated place in administrative area 08. These facts shape the local comparable search, not the price.

What must a project estimate add?

For a London office project, reconcile workplace fit-out grade, services density, floorplate efficiency and vertical transport. Use a consistent gross-floor-area basis and record the following before reliance.

Price-level normalization worksheet

For a validated reference rate R from a country with construction PLI P, the transparent screening calculation is R × (217.0 ÷ P). At P = 100 the dimensionless ratio is 2.170; no world cost rate is asserted. Keep the reference rate's currency, base date, area basis and scope attached.

Sources and method

National screening observation from the World Bank ICP 2021 API and ICP data documentation; locality and population from the GeoNames CA dump (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 6058560). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Frequently asked questions

Does the 217.0 index give a office cost per m² for London?

No. 217.0 is the World Bank ICP 2021 national construction price-level index for Canada, with the world equal to 100. It is a cross-country screening statistic, not a London CAD/m² rate, escalation index, quote or tender estimate.

How should a London office estimate replace this screening benchmark?

Collect current London comparables on a consistent gross-floor-area basis, reconcile workplace fit-out grade, services density, floorplate efficiency and vertical transport, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
