Strata Surveying & Retrofit Ltd
Subcontract Delivery for Consultancies

Field Capacity You Can Turn On, and Turn Off

You have won the programme. We are the survey team that delivers the volume under your contract, to your methodology and in your template, without you carrying the headcount past the end of it.

The Problem Is Never Winning the Work

It is several thousand properties, a fixed window, and a headcount you cannot justify carrying once the programme closes. Agency assessors solve the number and create a quality problem: inconsistent evidence, re-surveys, a QA burden that lands back on your team, and a client who eventually notices.

Strata is a dedicated field delivery team you can scale up for a programme and stand down at the end of it. Seven DEA-qualified surveyors working as one crew, under one QA regime, running on our own programme management system. You keep the client relationship, the methodology and the report. We deliver the field volume and hand back clean data.

Your Name on the Report

White-label by default. Resident-facing letters carry the wording you agree, reporting runs through your project lead, and we do not approach your client. Non-circumvention in writing if your client requires it.

One Team, One Standard

The same in-house surveyors on every programme, trained to one field work instruction with same-day QA on every evidence pack. No agency churn, which is where re-survey rates and inconsistent evidence come from.

Your Template, Not Ours

Field structure, value lists and property references agreed before the first survey rather than reconciled after the last one. Sample export available before award so your systems team can test the import.

Access Managed End to End

Letters, SMS, WhatsApp, calls and door knocks, every attempt logged against the property. The part of a programme that actually decides whether it lands on time, taken off your project managers.

Live Client Dashboard

Your Project Manager Stops Chasing Us for Progress

A dashboard login from day one showing completion per property, status, EPC results as they are lodged, the exception log with a reason on every entry, and a full CSV export whenever you want it. Your PM reports to the client from live data instead of waiting on our weekly email.

RdSAP 10

Capacity Is Tighter Than It Was, and That Is the Point

RdSAP 10 has been live since June 2025. Every window measured individually, lighting counted by type, ventilation categorised. Every domestic EPC now takes materially longer, and assessor capacity across the market tightened at the same moment social housing volumes rose towards the 2030 EPC C obligation.

Our field app enforces the RdSAP 10 data capture at the property, so a survey that has not recorded what the methodology requires does not pass through as complete.

Scope Limits, Stated Up Front

The fastest way to cost a consultancy money is a subcontractor who agrees to everything at tender and discovers the gap in delivery. So the boundary is published rather than negotiated.
