NWT Energy

What NWT Energy does

NWT Energy (legal entity: NWT International Ltd, registered in England and Wales, company number 04433099) is a UK-based commercial solar PV specialist founded in 2010 by Michal Galda and Tim Haffenden as an independent UK counterpart to NWT Europe. The company designs, installs, and operates commercial-scale solar PV systems for property owners across the agricultural, commercial real estate, industrial, manufacturing, retail, and institutional sectors, with additional exposure to residential battery storage and LED lighting retrofits. Core offerings comprise new solar PV installations, operations and maintenance across a portfolio of over 320 commercial-scale UK sites, certified installation of Tesla Powerwall and sonnen battery storage systems, and a dedicated PV consultancy service covering system design, feasibility studies, tender specifications, project management, and post-installation inspections.

The company's technology stack is centred on established Tier-1 solar components, including SolarEdge inverters and power optimisers, REC and SunPower PV modules, and ABB and SMA inverters, supplemented by QLEEN rotating brush cleaning systems for O&M. NWT Energy holds MCS (Microgeneration Certification Scheme) certification and NAPIT registration, providing the regulatory credentials required for UK commercial solar work. Co-founder Tim Haffenden's qualifications as a fully qualified electrician and G99 relay tester enable NWT to support Accelerated Loss of Mains Change Program (ALoMCP) adjustments and to execute installations on challenging sites including asbestos roofs, concrete-framed buildings, and logistically complex locations.

NWT Energy operates an enterprise field sales and direct-engagement go-to-market model, working with property owners, managing agents (including Savills, Strutt and Parker, and Jaguar Building Services), and end clients across the UK. Revenue is generated through a mix of one-time installation project revenue (new PV systems, battery storage, LED lighting), recurring O&M subscription-style revenue across the 320+ site portfolio, and professional services revenue from PV consultancy. Pricing is bespoke per project, with disclosed customer financial returns of 10-17% on solar investments and systems designed for 25-30 year operating lives. The company employs 11-50 staff across headquarters in Haywards Heath and a registered office in Crawley, West Sussex.
