Daily Deployment

Scheduled by Area, Not by Postcode Lottery

Every programme is routed through our Survey Programme Management System so each surveyor's day is grouped by area. That is what lets scattered social housing stock across several boroughs be surveyed on one consistent weekly rate, and why we can commit to that rate before mobilisation.

Housing stock in London and the South East ranges from Victorian terraces and inter-war semis to post-war estates and new-build blocks. Our surveyors work across all of them daily.

Our office is in Harrow, so the borough and its neighbours are our home patch. See EPC and stock condition surveys in Harrow.
