Direct answer

For early retail construction cost planning in Wolverhampton, the World Bank ICP reports a 2021 United Kingdom construction price-level index of 155.3, with the world equal to 100. This is a national comparison—not a Wolverhampton GBP/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across United Kingdom in 2021; it does not measure a Wolverhampton market basket or current retail tenders. GeoNames 2633691 records the locality at 52.5855, -2.1230, with snapshot population 263,700. That ranks Wolverhampton 28 of 50 listed places, while Walsall is the nearest listed peer at about 9 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 155.3 construction index mean?

The World Bank ICP 2021 construction PLI for United Kingdom is 155.3, 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 retail work in Wolverhampton costs 1.553 times a current world rate.

Which Wolverhampton inputs are known?

The reproducible locality point is 52.5855, -2.1230 (GeoNames 2633691). Its snapshot population is 263,700, ranked 28 of 50 listed places; GeoNames classifies it as a second-order administrative seat in administrative area ENG. These facts shape the local comparable search, not the price.

What must a project estimate add?

For a Wolverhampton retail project, reconcile shell condition, tenant fit-out, servicing, trading constraints and landlord works. Use a consistent gross-floor-area basis and record the following before reliance.

Estimate field	Screening record	Project requirement
National context	ICP 2021 PLI 155.3	Retain only as dated cross-country context
Local GBP/m² rate	Not supplied	Current comparable with named source and base date
Area and scope	Gross floor area; scope unresolved	Measurement standard, specification and procurement route
Additions	Not supplied	Taxes, fees, site work, contingency and escalation
Review	Automated source and arithmetic QA	Qualified local cost review

Price-level normalization worksheet

For a validated reference rate R from a country with construction PLI P, the transparent screening calculation is R × (155.3 ÷ P). At P = 100 the dimensionless ratio is 1.553; no world cost rate is asserted. Keep the reference rate's currency, base date, area basis and scope attached.

Input	Recorded value	Release condition
Target national PLI	155.3 (World = 100, 2021)	Screening context only
Reference construction PLI P	User-supplied from the same ICP classification/year	Must match reference rate country
Validated reference rate R	User-supplied	Named source, currency, date, area and scope
Local Wolverhampton adjustment	Not asserted	Replace with current local comparable evidence
Result status	Screening normalization	Not a budget, quote or tender estimate

Frequently asked questions

Does the 155.3 index give a retail cost per m² for Wolverhampton?

No. 155.3 is the World Bank ICP 2021 national construction price-level index for United Kingdom, with the world equal to 100. It is a cross-country screening statistic, not a Wolverhampton GBP/m² rate, escalation index, quote or tender estimate.

How should a Wolverhampton retail estimate replace this screening benchmark?

Collect current Wolverhampton comparables on a consistent gross-floor-area basis, reconcile shell condition, tenant fit-out, servicing, trading constraints and landlord works, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
