Traditional Fragmented Model vs Strata Dual-Visit Model
See how our unified surveying delivery slashes procurement administration, resident complaints, and overall framework costs.
Fragmented 2-Visit Process
Multiple Contractors / High Disruption- ✕ Two Separate Resident Appointments Tenants must stay home twice (once for EPC assessor, once for building surveyor), leading to missed visits.
- ✕ 75% - 80% Access Success Rate High resident refusal and abortive call-out fees multiply contract management headaches.
- ✕ Inconsistent Data Taxonomies Energy assessors and building surveyors record conflicting room dimensions and heating data.
- ✕ Separate Subcontract Invoices Double procurement administration, double booking letters, and delayed lodgements.
The Strata Dual-Visit Model
Single Attendance · 40% Admin Savings- ✓ One Single Resident Appointment (45 mins) Dual-qualified field surveyor captures both RdSAP Energy and 30-year Stock Condition metrics together.
- ✓ Verified First-Time Access Rate, Well Above Industry Average Proven track record across London housing associations with minimal abortive visit friction.
- ✓ Unified 18-Point GPS Photo Audit Single authoritative dataset feeding both national EPC registers and asset databases.
- ✓ Guaranteed SLA Lodgement Backing < 8 days EPC lodgement and 12 days stock condition reporting with zero backlog.
