Industry Challenges
Building remediation projects face unique complexities and regulatory pressures:
Regulatory pressure - Building Safety Act, BSR compliance deadlines
Cost uncertainty - Hidden defects discovered during works
Occupied buildings - Works around residents, minimal disruption
Funding challenges - Grant applications, leaseholder charges
Complex interfaces - Multiple trades, phasing requirements
The Risk
“A 10% cost overrun on a £5M cladding remediation project represents £500,000 in unexpected costs. With BSR deadlines looming and complex funding arrangements, accurate cost estimation is critical for project viability and leaseholder consultation.”

BSR Submission Cost Estimation
We provide detailed cost breakdowns for BSR-related activities:
Registration & Compliance (Typical Costs): - BSR registration application: £2,000-4,000 - Building Safety Case preparation: £15,000-35,000 - Resident engagement strategy: £5,000-12,000 - Mandatory occurrence reporting system: £3,000-8,000 - Annual compliance review: £8,000-15,000
Professional Team Requirements: - Principal Designer appointment - Principal Contractor obligations - Building Safety Manager (in occupation) - Accountable Person duties - Competence framework compliance - Change control management
Key BSR Cost Drivers We Quantify:
Enhanced documentation requirements
Digital information management (ISO 19650)
Competence verification systems
Gateway submission preparations
Golden thread information requirements
Resident engagement obligations
Remediation-Specific BSR Requirements
For existing HRBs requiring remediation, BSR compliance adds specific cost implications:
Enhanced Surveys & Assessments - Type 4 Fire Risk Assessment - Intrusive building investigations - Structural integrity reviews - External wall system (EWS1) assessments - Golden thread data creation
Compliance Documentation - Safety case updates during works - Change control procedures - Contractor competence verification - Mandatory occurrence reporting - Resident notification protocols
Post-Remediation Requirements - Updated building safety information - Revised safety case submission - As-built BIM models (ISO 19650) - Resident information updates - BSR notification of completion
Important BSR Deadline Context
All existing HRBs must be registered with BSR. Accountable Persons face significant penalties for non-compliance. Our cost estimates help building owners budget for mandatory compliance upgrades alongside remediation works.

Frequently Asked Questions
Q: Can you estimate remediation costs without intrusive surveys?
A: We can provide indicative budgets based on visual surveys and typical defect patterns, but we strongly recommend intrusive investigation before finalizing estimates. We typically include 20-25% contingency for non-intrusive estimates vs 10-15% for fully surveyed buildings.
Q: How do you handle unknown defects discovered during works?
A: Our estimates include risk-based contingencies (typically 15-25%) calculated from intrusive survey findings and industry benchmarks. We also provide a risk register identifying potential additional costs with probability assessments.
Q: Can you support Building Safety Fund (BSF) applications?
A: Yes, we regularly prepare cost documentation for BSF and other grant applications. We provide the detailed breakdown formats required by funding bodies and can support the technical review process.
Q: What about phasing to keep residents in occupation?
A: We specialize in occupied building remediation. Our estimates include phasing strategies, protection costs, temporary works, resident liaison, and the cost premium for working around occupants (typically 15-20% additional).
Q: How accurate are remediation estimates given the unknowns?
A: With proper intrusive surveys, we achieve ±5-8% accuracy on remediation projects (vs our standard ±5% for new build). The additional variance accounts for unexpected defects. We provide clear contingency breakdowns for transparency.
Q: Can you estimate alternative cladding systems for comparison?
A: Absolutely. We regularly compare different compliant cladding systems (brick slip, render, metal panels, terracotta) with full cost implications including performance characteristics, maintenance, and longevity considerations.
Q: What about asbestos or other hazardous materials?
A: We include allowances for asbestos surveys and removal when building age suggests likely presence. We work with specialist asbestos surveyors to refine removal costs and include proper disposal, air monitoring, and notification costs.
Q: What’s your fee structure for remediation projects?
A: Fees vary based on building size, defect complexity, and urgency. As a rough guide: - Small building (20-50 units): £3,500-6,000 - Medium building (50-100 units): £6,000-10,000 - Large building (100-200 units): £10,000-16,000 - Complex multi-block: £16,000-30,000
