LHW Partnership

What LHW Partnership does

LHW Partnership LLP is a UK-based specialist engineering consultancy founded in 2013 by James Hoare in Leighton Buzzard, focused on renewable energy and energy efficiency across solar PV, wind, battery storage, and heat pumps. The firm operates as a horizontal professional services consultancy serving private, commercial, community, not-for-profit, and public sector clients, with over 1,000 project assignments completed since inception and a reported 95% client retention rate. Its core proprietary technology is Yieldworks, an in-house developed modelling system that simulates renewable system sizing at 1-minute granularity and module by-pass diode electrical precision, significantly exceeding the hourly resolution of standard tools such as PVSyst and PV*Sol. The firm is differentiated by a rare multi-technology capability, deep heritage dating back to the UK’s first wind farms in 1991 and battery storage work since 2000, and unique regulatory assets including a CAA drone approval with a 20-metre reduced area of control.

Revenue is generated through project-based professional services engagements spanning feasibility, design, due diligence, technical advisory, drone and thermographic inspection, grid connection applications, operations and maintenance, and expert witness services for civil and criminal disputes. Customer segments are diversified across utilities and developers, commercial and industrial enterprises, local authorities, heritage organisations, residential clients, the legal sector, and community energy NGOs. Distribution is entirely direct, with no disclosed pricing, and customer acquisition is driven by referrals, technical publications, and active participation in industry standards bodies (IET, MCS, RICS, Fire Protection Agency). Strategic positioning has shifted in 2023-2024 toward standards authorship (RC62 rewrite, IET BESS Code of Practice chair) and international expert witness work, including a 1.2 GWp PV farm investigation in the UAE in 2023.
