The Building Safety Levy is live. Every residential building control application since 1 October 2026 is in play.

England's new levy charges developers per square metre of new residential floorspace - rates set in law for each local authority area, higher where house prices are higher. It lands through the building control process and must be paid before completion or occupation, whichever is earlier. If you develop 10 or more dwellings, the question is not whether it applies, but how much it costs and which exemptions you can prove.

Free check: is your application chargeable?

Four questions from the regulations and GOV.UK guidance. Nothing you pick leaves this page.

Does the work create new dwellings or student (PBSA) bedspaces - new build, extension, or change of use? Counting the whole planning permission (not just this application), is it 10+ dwellings or 30+ PBSA bedspaces? Is the client a non-profit registered provider of social housing? (Joint ventures: every party must be one) Was or will the building control application be submitted on or after 1 October 2026?

Answer all four to see where you stand.

The traps that catch small developers

Trap	How it works
Phasing trap	Splitting a 24-dwelling permission into three 8-dwelling applications does not avoid the levy - the planning permission scale is what counts
Resubmission trap	A pre-October 2026 application that is rejected and resubmitted becomes liable
Change-of-use trap	Converting an existing building into dwellings can be chargeable too
Cash-flow trap	Payment falls due before completion or occupation - earlier than most developers expect
Exemption-evidence trap	Social housing, supported housing and other uses can be exempt dwellings - but get the exemption confirmed in writing by the local authority

A discounted rate applies to qualifying "previously developed" (brownfield) sites, defined in the regulations.

The Building Safety Levy Pack

Chargeability worksheet: the three tests (residential floorspace, major development scale, exempt client) worked through for each site.
Floorspace cost estimator (Excel): chargeable floorspace by dwelling type x your local authority rate = a budget figure for the appraisal.
Exemptions checklist: under-threshold developments, exempt persons, exempt dwelling types - and the written-confirmation step.
Application-to-occupation timeline: what to file, when the levy liability notice arrives, when variations trigger a revised notice, and where payment lands in your cash flow.
The five traps, with the regulation references behind each.

What it is not: templates and worksheets, not legal or tax advice. The collecting authority's levy liability notice is the actual bill - this pack gets you ready for it.

Questions

My site is 8 dwellings. Am I clear? Only if the planning permission is for under 10 dwellings (or under 30 PBSA bedspaces). If the wider permission is a major residential development, your smaller application is still chargeable. And exempt dwellings (social, supported) do not count toward the charge but do not shrink the development's status either.

Where do I find my rate? The rates are set per local authority area in the levy regulations (SI 2025/1236), weighted by house prices. The estimator takes your area's rate as an input and links you to the rate table.

Is this advice? No. It is a worksheet and checklist pack built from the GOV.UK levy guidance and the regulations. For a live project, confirm with the collecting authority or a qualified adviser.
