Cladding Crisis: What Block of Flats Owners Need to Know before 2026
Introduction
The 2017 Grenfell Tower tragedy changed everything for UK block of flats owners. What followed was a cascade of fire safety regulations, cladding surveys, and eye-watering remediation costs that have left thousands of property owners in financial distress.
If you’ve received an EWS1 form rejection, a fire risk assessment flagging dangerous cladding, or a six-figure remediation bill, this guide is for you. We’ll break down your legal obligations, potential costs, funding options, and alternative solutions including selling your block to specialist buyers.
Understanding the UK Cladding Crisis
What Happened?
Following the Grenfell Tower fire in June 2017, which claimed 72 lives, investigations revealed that combustible cladding materials (particularly Aluminium Composite Material or ACM) were widely used on UK buildings.
The government responded with:
- Immediate ACM cladding bans on new buildings
- Retrospective fire safety assessments for existing buildings
- The Building Safety Act 2022
- Various remediation funding schemes
How Many Buildings Are Affected?
Government estimates suggest:
- Over 11,000 buildings require cladding remediation
- Approximately 700,000 homes are impacted
- £15+ billion total estimated remediation costs
- Average cost per building: £1.5-£3 million for medium-rise blocks
Types of Dangerous Cladding
ACM Cladding (Aluminium Composite Material)
The most dangerous type, with a combustible polyethylene core. This is what was used on Grenfell Tower.
Risk Level: Severe
Typical Removal Cost: £30,000-£70,000 per building
HPL Cladding (High-Pressure Laminate)
A decorative cladding system that can be combustible under certain conditions.
Risk Level: High
Typical Removal Cost: £25,000-£50,000 per building
EPS/PIR Insulation
Expanded polystyrene or polyisocyanurate foam insulation used behind cladding panels.
Risk Level: Medium to High
Typical Removal Cost: £40,000-£100,000+ per building
Timber Cladding
Natural timber cladding without proper fire-resistant treatment.
Risk Level: Medium
Typical Removal Cost: £20,000-£60,000 per building
Your Legal Obligations as a Block Owner
The Building Safety Act 2022
Under this legislation, building owners (freeholders) have clear responsibilities:
For Buildings Over 18 Metres (High-Rise)
- Register with the Building Safety Regulator
- Appoint an “Accountable Person”
- Conduct regular fire risk assessments
- Maintain a Safety Case Report
- Report all fire safety incidents
- Fix identified issues within specified timeframes
Penalties for non-compliance: Unlimited fines and/or imprisonment
For Buildings 11-18 Metres (Medium-Rise)
- Less stringent requirements but still legally responsible
- Must ensure fire safety compliance
- May need EWS1 forms for mortgageability
For Buildings Under 11 Metres
- Standard fire safety responsibilities apply
- May still face cladding issues affecting insurance or sales
The Regulatory Reform (Fire Safety) Order 2005
This remains in force and requires all commercial and multi-occupancy residential building owners to:
- Conduct fire risk assessments
- Implement safety measures
- Keep records up to date
- Review assessments regularly
Non-compliance penalties: Up to 2 years imprisonment and/or unlimited fines

TOTAL: £792,800 (£33,000 per flat)
Funding Options for Cladding Remediation
1. Building Safety Fund (BSF)
Eligibility:
- Buildings 11 metres+ with unsafe cladding
- Built or refurbished between 1992 and June 2017
- Leaseholders who can’t afford to pay
Coverage:
- Up to 100% of cladding remediation costs
- Does NOT cover non-cladding issues
- Does NOT cover professional fees or waking watch
Status: Most funding already allocated, limited new applications accepted
Application Timeline: 6-12 months for approval, 12-36 months for works completion
2. Cladding Safety Scheme (CSS)
Replaced the BSF for medium-rise buildings (11-18 metres).
Coverage:
- Similar to BSF but expanded eligibility
- May cover buildings outside original BSF timeframes
Status: Check gov.uk for current application windows
3. Leaseholder Protections
Under the Building Safety Act 2022:
Full Protection (no costs):
- If property value under £325,000 (outside London) or £175,000 (in London)
- If you’ve owned the property for less than 5 years
Capped Costs:
- £10,000 maximum (outside London, property value over £175,000)
- £15,000 maximum (London, property value over £325,000)
Who Pays: Developers, building owners, or manufacturers depending on circumstances
4. Developer Contributions
The government has secured commitments from major developers to fund remediation of buildings they constructed. Check if your block’s original developer is on the pledge list.
5. Manufacturer Claims
Some building owners are pursuing legal claims against cladding manufacturers. This is complex, expensive, and can take years.
6. Service Charges
If no other funding is available, costs fall on leaseholders via service charges—but protections now apply (see above).
What Happens if You Can’t Afford Remediation?
The Reality
Many freeholders find themselves in an impossible situation:
- Funding applications rejected or insufficient
- Can’t sell the block (unmortgageable)
- Can’t afford remediation costs
- Leaseholders refusing to pay increased service charges
- Insurance premiums skyrocketing or coverage withdrawn
- Facing personal bankruptcy
Your Options
1. Negotiate Extended Payment Plans
Work with leaseholders to spread costs over longer periods, though this doesn’t reduce the total burden.
2. Refinance (If Possible)
Very difficult with cladding issues, but some specialist lenders may help if remediation is funded and underway.
3. Government Intervention
Keep lobbying your MP and waiting for additional funding schemes, though this is uncertain.
4. Sell to a Specialist Buyer
Companies like Citywide Blocks buy blocks with cladding issues, factor remediation costs into their offer, and take on the responsibility.
Case Study: From £680k Cladding Bill to Clean Exit
The Situation
A property investor in Manchester owned a 16-unit block built in 2003. A fire risk assessment identified:
- Dangerous ACM cladding requiring removal
- Inadequate compartmentation
- Non-compliant fire doors
- Total estimated remediation: £680,000
The Building Safety Fund application was rejected (block built after 1996 cutoff initially). Leaseholders couldn’t afford £42,500 each. The freeholder faced:
- Waking watch costs of £18,000/month
- Insurance renewal refused
- Mortgage lender demanding immediate action
- Personal guarantee on the freehold loan
The Solution
Sold to a specialist block buyer within 5 weeks:
- Buyer conducted own fire safety assessment
- Offered price accounting for full remediation costs
- Covered all legal fees
- Completed before next mortgage payment due
- Owner avoided bankruptcy
Final outcome: Owner lost equity but escaped crushing debt and restored financial stability.
The EWS1 Form Explained
What Is It?
The External Wall System (EWS1) form is a fire safety assessment document that confirms whether a building’s external walls pose a fire risk.
Why It Matters
Most mortgage lenders require an EWS1 form before lending on flats in buildings with external cladding. Without it:
- Properties become unmortgageable
- Sales fall through
- Property values plummet
- Remortgaging becomes impossible
Who Completes It?
Only qualified fire engineers or building surveyors with specific expertise can complete EWS1 forms.
Cost: £2,000-£10,000+ depending on building complexity
Possible Outcomes
B1 Rating: Remedial works required (worst outcome)
B2 Rating: Professionals recommend remediation
A1 Rating: No combustible materials (best outcome)
A2 Rating: Combustible materials present but acceptable
Insurance Challenges for Affected Blocks
Premium Increases
Blocks with cladding issues face dramatic insurance cost increases:
- 200-500% increases common
- Some blocks seeing £5,000/unit annual premiums
- Group policies often cancelled entirely
Coverage Limitations
Insurers may:
- Exclude fire damage claims
- Require waking watch as condition of coverage
- Impose strict remediation timelines
- Refuse to renew policies
Finding Alternative Cover
Specialist insurers exist but charge premium rates. Some blocks become effectively uninsurable, creating legal and mortgage problems.
Impact on Property Values
Sales Data Shows
Properties in blocks with known cladding issues have seen:
- 20-40% value reductions common
- Some properties becoming unsaleable
- Transaction volumes down 60-80%
- Time on market increasing by 6-12 months
The Unmortgageability Problem
Without an acceptable EWS1 form:
- Cash buyers only (dramatically reducing buyer pool)
- Values drop to reflect this limitation
- Buy-to-let investors avoid entirely
Leaseholder Revolt: Legal Considerations
Service Charge Disputes
Many leaseholders are refusing to pay cladding remediation costs via service charges, leading to:
- First-tier Tribunal cases
- Court proceedings
- Leasehold forfeiture threats
- Collective action groups
Your Legal Position as Freeholder
Under lease terms, you typically have the right to recover costs via service charges, BUT:
- New legislation limits leaseholder liability
- Courts increasingly sympathetic to leaseholders
- Legal costs of enforcement may exceed recovery
- Negative publicity affects your other properties
Mediation Options
Consider alternative dispute resolution:
- RICS mediation services
- Leaseholder engagement forums
- Phased payment agreements
- Transparency in cost breakdowns
Waking Watch: The Temporary (Expensive) Solution
What Is Waking Watch?
A temporary fire safety measure requiring trained personnel to patrol buildings 24/7, watching for fire risks.
When Required
Fire and rescue services may require waking watch when:
- Dangerous cladding identified
- Before remediation begins
- Fire alarm systems inadequate
- Evacuation plans unclear
The Cost
Typical expenses:
- £500-£1,500 per day
- £15,000-£45,000 per month
- £180,000-£540,000 per year
For a 20-unit block, this means £9,000-£27,000 per flat per year in service charges just for waking watch.
Alternatives
Some blocks have replaced waking watch with:
- Enhanced fire detection systems (£30k-£60k)
- Smoke alarms in every room
- Heat sensors in common areas
These are one-time costs vs. ongoing waking watch expenses, but require fire service approval.
Regional Variations in the Cladding Crisis
London
- Highest number of affected buildings
- Most expensive remediation costs (£3m+ common)
- Stronger leaseholder protections due to higher property values
- More specialist buyers operating
Manchester & Northwest
- Significant number of affected buildings from 2000s construction boom
- Medium-range remediation costs (£400k-£800k typical)
- Mix of high-rise and medium-rise issues
Birmingham & Midlands
- Growing problem identification as assessments continue
- Costs proportionally higher vs. property values
- Fewer funding options approved
Scotland
- Separate building regulations and legal framework
- Different funding schemes available
- Generally fewer affected buildings
Should You Sell or Remediate?
Consider Selling If:
✓ Remediation costs exceed 30% of property value
✓ Funding applications rejected
✓ Can’t afford interim measures (waking watch)
✓ Leaseholders unable or unwilling to pay
✓ Insurance cancelled or unaffordable
✓ Mortgage lender demanding immediate action
✓ Stress affecting health or other investments
✓ You’re nearing retirement and want to exit property investment
Consider Remediating If:
✓ Funding secured covering 80%+ of costs
✓ Strong cashflow from other sources
✓ Leaseholders cooperative and able to pay
✓ Long-term hold strategy (10+ years)
✓ Property values significantly exceed costs
✓ You have development/construction experience
How Specialist Buyers Handle Cladding Issues
Companies like Citywide Blocks approach cladding problems differently:
1. In-House Expertise
They employ fire safety consultants and building surveyors who understand the complexities and costs.
2. Established Contractor Relationships
Years of experience mean they have competitive pricing for remediation works.
3. Risk Tolerance
Unlike residential buyers, they’re willing to take on buildings with known issues.
4. Speed
No mortgage requirements or lender surveys mean they can move quickly—often within weeks.
5. Transparent Pricing
They show exactly how remediation costs factor into their offer, so you understand the calculation.
Taking Action: Your Next Steps
1. Get a Professional Fire Risk Assessment
If you haven’t already, commission a Type 4 external wall assessment. This costs £3,000-£8,000 but is essential for understanding your exact situation.
2. Check Funding Eligibility
Visit gov.uk and check current Building Safety Fund and Cladding Safety Scheme criteria.
3. Engage with Leaseholders Early
Transparent communication prevents costly disputes later. Consider a residents’ meeting to discuss options.
4. Get Multiple Remediation Quotes
Costs vary significantly between contractors. Obtain at least three competitive quotes.
5. Explore All Exit Options
Speak with specialist block buyers to understand what offer they might make. Compare this with the cost and timeline of remediation.
6. Consult Professionals
- Property lawyer specializing in leasehold
- Accountant for tax implications
- Financial advisor for long-term planning
