What Oakes Energy Services does

Oakes Energy Services is a UK commercial HVAC and renewable energy contractor that designs, installs, and maintains low-carbon technology systems for enterprise, public sector, and industrial customers. Founded in 2007 and headquartered in Houghton-le-Spring with a second office in Newcastle upon Tyne, the company has executed projects across England, Scotland, and the wider UK over 19 years. Its technology portfolio spans solar PV panels, battery energy storage systems, air and ground source heat pumps, combined heat and power, EV charging infrastructure, biomass heating, wind turbines, hydrogen-fired boilers, commercial gas boilers, air conditioning, and ventilation, plus solar thermal and mine water extraction heating. Notable installations include multi-site PV rollouts for Northern Gas Networks (8 sites supporting the utility's net-zero-by-2031 strategy), solar PV for Sunderland City Council's Hetton Swimming Baths (193.6 kWp) and Sunderland Aquatics Centre (46.35 kWp), a 137 kWp system for ABB following the award-winning Stonehouse 1MW solar farm with 0.5MW BESS, chiller replacements for NHS Trusts, and ground source heat pumps for agricultural sites such as Middle Cave Farm. The company delivers through three revenue streams: one-time installation projects (won via competitive tendering on cost and quality), recurring maintenance and servicing contracts (annual servicing, safety checks, emergency call-outs), and funded solutions (Power Purchase Agreements, asset finance, and Heat-as-a-Service) delivered through its March 2026 partnership with MTFD, which provides third-party development capital, planning, DNO approvals, and ongoing asset management. Oakes operates as a subsidiary of PHS Home Solutions Limited, whose ultimate parent is the German engineering group Viessmann (founded 1917), giving it group-level financial backing and brand credibility while competing in UK commercial decarbonisation tenders.
