356-Property EPC & Stock Condition Survey Programme

The Client & Programme Context

A prominent South East London housing association required a rapid baseline survey across 356 scattered residential units throughout Bromley, Lewisham, and Bexley to support upcoming energy decarbonisation grant applications and 30-year asset management planning.

The Operational Challenge

• Tenant Disruption: Booking two separate surveyor visits (one for energy, one for stock condition) risked significant resident fatigue, refusal rates, and administrative overhead.
• Tight Timeline: All data needed to be lodged and delivered into the client’s Keystone asset management database within an 8-week window.
• Evidentiary Rigour: Complete photographic audit trails were required to support potential Social Housing Decarbonisation Fund (SHDF) audit scrutiny.

The Strata Solution

Strata deployed its combined survey delivery model, pairing accredited Domestic Energy Assessors and qualified Building Surveyors using our proprietary AppSheet SPMS mobile software:

1. Single Attendance Surveying: Surveyors captured all RdSAP energy metrics alongside full 30-year lifecycle component ratings during one 45-minute resident appointment.
2. 18-Point GPS Photo Checklist: Every room, window, elevation, HVAC asset, and roof space was recorded with GPS metadata and timestamped images.
3. Real-Time Live Portal Access: The client’s asset management team had real-time visibility over completed addresses, no-access escalations, and draft certificate uploads.

The Results & Delivery Metrics

The entire 356-property programme was completed in 7.2 weeks—comfortably ahead of the 8-week client deadline—with 100% of EPC certificates lodged to the national register within an average of 6.4 business days from field inspection.
