Surveying & Retrofit Services Built for Programme Scale
High-capacity, multi-accredited survey programmes delivered with operational precision for social housing, public sector frameworks and private portfolios.
Dedicated High-Volume Field Delivery

Delivered by Our Own Surveyors
Seven DEA-qualified surveyors, two of whom also hold the Level 3 Award in Domestic Retrofit Assessment, deployed daily from our Harrow base across London and the South East.
The Combined EPC + Stock Condition Visit
Procuring an energy assessor and a building surveyor separately means two letters, two appointments and twice the chance of a no-access. Because our surveyors are DEA-qualified and trained in stock condition capture, one visit produces a lodged EPC and a full condition record. Residents are disturbed once; your programme runs on one schedule.
Traditional Two-Contractor Model vs Strata Combined Visit
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 Combined-Visit Model
Single Attendance · One Dataset- ✓ One Single Resident Appointment (45 mins) Dual-qualified field surveyor captures both RdSAP Energy and 30-year Stock Condition metrics together.
- ✓ Every Access Attempt Logged, Nothing Written Off Letter, SMS, call and door-knock attempts recorded against each property, with a three-tier no-access protocol and a reason on every exception.
- ✓ Unified 18-Point GPS Photo Audit Single authoritative dataset feeding both national EPC registers and asset databases.
- ✓ Guaranteed SLA Lodgement Backing 2-day lodgement guarantee across EPC and Stock Condition reporting, with zero backlog.
356 Homes. One Visit Each. Zero Backlog.
The combined model is how our flagship 356-property programme was delivered across South East London: EPC and stock condition data from a single appointment per home, lodged within a 2-day SLA and exported to the client's asset system.
