356-Property EPC & Stock Condition Survey Programme
How Strata delivered combined EPC assessments and stock condition surveys across 356 social housing homes, one resident visit each, with a 2-day lodgement SLA and zero backlog.
The Programme Context
A London housing association needed a current energy and condition baseline across 356 scattered residential units in South East London to support decarbonisation funding applications and 30-year asset management planning. The programme was delivered by Strata's field team working alongside the client's appointed consultancy.
The Operational Challenge
- Resident disruption: booking separate energy assessor and building surveyor visits risked resident fatigue, refusals and double the administrative overhead.
- Data consistency: two surveyor types capturing the same homes at different times produces two datasets that never quite agree.
- Evidential rigour: a complete photographic audit trail was required to withstand funder and accreditation body scrutiny.
- Integration: the condition data had to land in the client's asset management system in its own element structure, not a contractor spreadsheet.
One Appointment. Both Datasets. Same Surveyor.
Strata deployed its combined visit model: DEA-qualified surveyors trained in stock condition capture, working from a single survey template on our field app that collected RdSAP inputs and element-level condition ratings in the same visit.
- Single attendance: all RdSAP energy inputs and component condition and remaining-life data captured in one resident appointment.
- 18-point GPS photo checklist: every elevation, room, heating asset and roof space recorded with geotagged, timestamped images.
- Live client portal: the client's asset team could see completed addresses, no-access escalations and lodgement references as the programme ran.
Mid-Programme Snapshot: 234 of 356 Complete, SLA on Track
This is the client dashboard part-way through the programme (client name and addresses redacted): completed, scheduled, outstanding and exception counts; the EPC band distribution of certificates lodged so far; and the SLA position. The property tracker below it showed each home's before-and-after rating and visit count.
The Results
- 356 homes surveyed with one visit each, halving resident contact compared with separate EPC and stock condition appointments.
- Every EPC lodged within the 2-day SLA following same-day QA, with zero lodgement backlog at any point in the programme.
- Complete photographic evidence for every property under the 18-point checklist.
- Condition data exported to the client's asset management system in its own element structure, ready for investment planning.
The same model is now the default for every combined programme we deliver, and the platform built to run it has become our Survey Programme Management System.
