Building Safety Levy

The levy will come into effect on 1 October 2026 and will apply if you are applying for building control approval for:

• One or more new or converted homes (including any self-contained accommodation/annex)
• One or more purpose-built student accommodation bedspaces

Not all new developments have to pay the levy. You must consider whether your development meets the levy charging conditions below and complete the relevant section within the application form. The application form will be available soon.

There are charges for the levy when the development is a major residential development, defined as:

• 10 or more homes
• 30 or more new bedspaces

The works have to create new residential floorspace.

Conversions or changes of use from non-residential to major residential developments are also subject to the levy.

The levy does not apply to:

• registered non-profit social housing providers 
• social housing
• supported housing
• school accommodation
• accommodation for domestic abuse victims
• hospitals
• children’s homes and residential family centres
• hotels and hostels
• monasteries, nunneries and similar establishments
• care homes and hospices
• secure residential accommodation (e.g. prisons)
• almshouses
• temporary accommodation for homeless people
• armed forces accommodation
• Ministry of Defence or Crown properties

The levy is charged per square metre (sqm) of floorspace.

• previously developed land (brownfield) - £19.41 (per sqm)
• non-previously developed land - £38.81 (per sqm)

Floorspace

Floorspace is measured using Gross Internal Area (GIA).

• included: communal areas used mainly by residents
• excluded: areas used mainly by the general public

Previously developed land (brownfield)

Chargeable developments constructed on previously developed, or brownfield, land may be eligible for a 50% levy discount, provided that at least 75% of the site satisfies the regulatory definition of a "previously developed site". You can find the full definition of Previously Developed Land in Annex 2: Glossary of the National Planning Policy Framework.

Future reviews on charges

From year two onwards, levy rates and exclusions will be reviewed every three years by the Secretary of State.

Before starting work, you must submit a commencement notice within 2 working days, with supporting levy information.

Stage 3: Our assessment

We will look over the information you provide and we will issue either:

• eight weeks (if a spot check is required)

Stage 4: Pay the levy

The levy must be paid in full. Details of how to pay the levy will be available soon.

Stage 5: Completion certificate

A completion certificate will only be issued by us, once the levy has been fully paid.

The Building Safety Levy was introduced by the government following the Grenfell Tower fire in 2017, which exposed serious building safety issues across the country.

A number of government reviews identified widespread problems in the design, construction and regulation of high-rise residential buildings. As a result, significant work is required to fix unsafe buildings, particularly those with fire safety defects.

The government has decided that the cost of fixing these issues does not fall on leaseholders. Instead, the costs will be met by:

• contributions from developers through legal agreements
• The Residential Property Developer Tax
• The Building Safety Levy

The Building Safety Levy is intended to ensure that the development industry makes a fair and proportionate contribution towards the cost of making buildings safe.

The levy is designed to:

• support the funding of building safety remediation across England
• make sure that those involved in residential development contribute to fixing historic safety defects
• reduce the financial burden on leaseholders and residents
• help create a safer and more accountable construction industry

How it fits into the wider building safety system

The levy forms part of a wider programme of building safety reforms, including:

• The Building Safety Act 2022
• a new regulatory regime for higher-risk buildings
• stronger responsibilities for developers, building owners and duty holders
• increased oversight from the Building Safety Regulator

Together, these changes aim to improve building safety standards and restore public confidence in the construction and housing sectors.
