THE BRIEF
Programme Scale With Operational Precision
A London housing association required a comprehensive EPC and stock condition survey programme across 356 occupied residential properties on the Downham estate in London and the South East. The programme covered BR1, BR3 and SE6 — a mix of houses, flats and low-rise blocks across 110+ streets, all occupied and all requiring individual tenant liaison and access coordination. Programme deadlines were fixed. Every EPC had to be lodged to Elmhurst WI01 v14 standard.
OUR APPROACH
Survey Programme Management System Deployed From Day One
Strata deployed our Survey Programme Management System from contract signature — tracking every property in real time from first contact to final report lodgement. Surveyors were assigned by geographic zone across BR1, BR3 and SE6 to minimise travel time and maximise daily throughput. Tenant liaison was managed centrally. Every failed visit was logged same day and rebooked within 24 hours.
THE OUTCOME
356 Properties. Under 2 Months. Every EPC Lodged.
The programme was delivered within the agreed timeframe. Every EPC lodged through our accredited assessor accounts to Elmhurst WI01 v14 standard. Stock condition data captured across all 356 properties. Full evidence pack issued at programme close.

WHAT IT MEANS FOR YOU
Programme Delivery Capability You Can Trust
Most surveying firms deliver single jobs. Far fewer can deliver 356 properties to deadline with documented data quality, real-time client visibility and audit-ready evidence packs. If you are planning a stock condition programme, EPC rollout or retrofit assessment — we would welcome the conversation.
