What Ecmk Ltd. does

ecmk Ltd. is a UK-based energy accreditation scheme and training provider, established in 2003 as one of the original government-approved Energy Accreditation Schemes in the country. The company operates accreditation across seven strands: Domestic Energy Assessor, Non-Domestic Energy Assessor (Level 3 and 4), Display Energy Certificates Assessor, Section 63 Assessor (Scotland), Retrofit Assessor, Retrofit Coordinator, and Legionella Risk Assessor. ecmk is also a TrustMark-approved scheme provider for Retrofit Assessors and Coordinators, enabling members to work on government-funded retrofit projects under ECO4, LAD3, the Boiler Upgrade Scheme, and the Home Upgrade Grant. The company is a wholly owned subsidiary of CoreLogic U.K. Limited, headquartered in Solihull with 11–50 employees, and operates exclusively within the United Kingdom.

The core technology stack consists of two complementary platforms: Assess+, a unified iOS mobile application consolidating EPC, Legionella, Retrofit, and Retrofit Coordinator workflows; and Assessor Hub 4.3, a BRE-approved web-based desktop portal aligned with the RdSAP 10 methodology, integrated with the UK EPC Registers and TrustMark Data Warehouse for compliant lodgement. Both products were launched or materially refreshed in March 2026. A third sub-brand, Plan Up, provides floor plan drawing software integrated with Assess+. Training delivery runs entirely online via Microsoft Teams, offering 30–35 courses per month, including the ABBE-awarded Cert DEA qualification, Retrofit Assessor courses, and 25+ CPD sessions.

ecmk monetises through three primary streams: recurring annual membership fees for accreditation (including free DEA annual membership for qualified assessors), per-transaction lodgement fees (£3.49+VAT per EPC and £5+VAT per Retrofit assessment, the lowest in the UK market and unchanged since 2016), and one-time training/CPD course fees ranging from £25 to £1,100+VAT. Distribution is direct via website application, inside sales, and Microsoft Teams training delivery; there are no reseller channels. Marketing is anchored on industry events including PEPA conferences, Energy Efficiency Awards, ECO4 conferences, and quarterly technical bulletins.
