What you need to know about cladding and other serious fire safety defects, including what is and isn’t covered by the Building Safety Fund.


Please see our News section for all the latest updates.

What is cladding?

Cladding refers to the material which is wrapped around the outside of a building to improve appearance and energy efficiency. It is not one specific material and may comprise multiple and different materials.

The safety of cladding is not just about the outer layer – it is the safety of the entire system which has to be assessed. This requires an intrusive inspection by a qualified individual to check the materials used and how they were installed. 

ACM Cladding

ACM (Aluminium Composite Material) is the type of cladding that was used on Grenfell Tower and which is now known to be dangerously combustible. Following the Grenfell Tower fire, the Government banned the use of ACM cladding on new buildings and set aside £600m to remove this type of cladding from existing high-rise buildings.

Non-ACM Cladding

Certain types of non-ACM cladding such as HPL (High Pressure Laminate) panels – common in the UK – are also considered to be a serious fire risk. In March 2020 the Government set aside an additional £1 billion for the remediation of non-ACM cladding systems from buildings over 18m.

Building Safety Fund (buildings over 18m)

Building Safety Fund Guidance for new applications from July 2022

Building Safety Fund Guidance for existing applications from 2020

The Building Safety Fund only covers removal of the external cladding system, i.e. “the components that are attached to the primary structure of a building to form a non-structural external surface. The cladding system includes the weather-exposed outer layer or ‘screen, fillers. Insulation, membranes, brackets, cavity barriers, flashing, fixings, gaskets and sealants.”

There are a range of other external and internal fire safety defects, however, that may need remediation including inadequate or missing fire breaks, combustible balconies and inadequate fire doors. These defects are not covered by the Fund.

A survey carried out by the Housing, Communities and Local Government Select Committee found that more than a third (34%) of respondents had missing or inadequate fire breaks while a further 30% noted combustible or missing insulation. Other issues reported included timber balconies or walkways (14%) and inadequate fire doors (5%) (Inside Housing 06/05/20).

Buildings under 18m

The Department of Levelling Up, Housing & Communities opened a pilot scheme in November 2022 to fund the remediation of buildings between 11 and 18 metres. See Funding for medium-rise buildings for more information.
