Free check: is your application chargeable?
Four questions from the regulations and GOV.UK guidance. Nothing you pick leaves this page.

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.
One-off. Instant download after payment. Word, Excel and PDF files.

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.
