This is an analysis of published government data
To be explicit about provenance: this article does not report a proprietary Hampstead Chartered Surveyors survey. It analyses the UK government's own published Building Safety remediation monitoring data and related official statistics (the Ministry of Housing, Communities & Local Government / Department for Levelling Up monitoring releases, and the Building Safety Regulator). Where we cite a figure we describe it as drawn from those public releases; readers should consult the latest GOV.UK release for current numbers, which update periodically.
We have written it this way deliberately - a clearly-sourced analysis of authoritative public data is more useful, and more honest, than an invented statistic.
Remediation is progressing slowly against a large backlog
The recurring story in the government's monitoring data is a large identified population of residential buildings with unsafe cladding and a completion rate that, while rising, has consistently lagged the scale of the problem - the published monitoring has reported thousands of buildings 11m+ identified with unsafe cladding and only a minority with works completed at the points measured. London, with its concentration of high-rise and mid-rise residential stock, represents a substantial share of that population.
The practical consequence for individual buildings is that being 'in a scheme' (Building Safety Fund or the Cladding Safety Scheme) is the start of a long process, not the end of one - eligibility, assessment, design, procurement and works each take time, and the programme timeline, not the individual leaseholder, sets the pace.
Implications for leaseholders and freeholders
For leaseholders: external wall status continues to affect mortgage-ability and sale, via the EWS1 process (a lender/valuer-facing record, not a life-safety certificate). Knowing your building's position - assessed or not, in a scheme or not, what the FRAEW concluded - is the single most useful thing to establish.
For freeholders, managing agents and accountable persons: the data underlines that evidence and sequencing matter. A building moves faster through a remediation programme when its FRAEW, fire risk assessment, compartmentation position and golden-thread information are already in order - the common cause of delay is missing information, not scheme capacity alone.
Establish your building's position first
Whatever the national numbers, the actionable move at building level is the same: establish the external wall position with a competent FRAEW / PAS 9980 appraisal, confirm the fire risk assessment addresses the structure and external walls, and assemble the building information a remediation programme will require. That converts a national backlog statistic into a building-specific plan.
Questions visitors commonly ask
Where does this data come from?
The UK government's published Building Safety remediation monitoring releases on GOV.UK and the Building Safety Regulator. It is public data; consult the latest release for current figures as they update periodically.
Did Hampstead Chartered Surveyors run its own survey for this?
No. This is explicitly an analysis of authoritative public data, not a proprietary survey. We do not publish invented statistics.
What should our building do in light of this?
Establish your external wall position with a competent FRAEW, confirm the fire risk assessment is current and covers the external walls, and assemble building information - that is what moves a building through remediation, regardless of the national backlog.
