Set out in a new Remediation Bill, the Ministry of Housing Communities and Local Government (MHCLG) has set deadlines of 2029 and 2031 based on building height.

Landlords of buildings 18m or higher will need to remove unsafe cladding by the end of the former.

Meanwhile, landlords of buildings 11-18m in height will have until the end of the latter to complete remediation work.

The new legislation will include “unlimited fines or imprisonment” for landlords who fail to meet these deadlines without reasonable excuses.

Named bodies, such as Homes England and local authorities, will also have the power to remediate buildings with unsafe cladding if landlords fail to do so.

The government has also recently laid regulations for the Building Safety Levy, expected to raise £3.4bn over the next decade to help fund remediation.

This will come into force from October 2026.

To maintain the viability of housing delivery, the levy has exemptions for affordable housing, supported housing and for development of fewer than ten dwellings as well as a discount for previously developed land.

Through Local Remediation Acceleration Plans, Mayoral Strategic Authorities will work closely with regulators and draw on local expertise to drive progress in their areas.

The government has provided over £5m to Metro Mayors to support them in this effort.

A new National Remediation system, now being rolled out by Homes England, will also support regulators with up-to-date building safety data and help hold failing landlords to account.

“[We are] sending a clear message to those responsible for a building still wrapped in unsafe cladding: act now or face the consequences,” said deputy prime minister and housing secretary Angela Rayner.

“Our Remediation Bill will include a new duty on you to make your building safe by a specified date, and new powers to impose serious penalties on those who fail to comply with the duty, and ultimately to bypass them if necessary to make the building safe.”
