MES Power Engineering

What MES Power Engineering does

MES Power Engineering is a UK-based high voltage electrical engineering services firm operating as a trading style of McKenzie Electrical Solutions Ltd., founded by engineer Neil McKenzie and headquartered in Kinellar, Aberdeenshire. The company delivers design, installation, testing, commissioning, and maintenance services for electrical distribution systems ranging from 400V up to 275kV, including specialist cable jointing up to 400kV, substation construction, and grid connections. It holds full and partial NERS accreditation under the Lloyds Register scheme, enabling it to operate as an Independent Connection Provider (ICP) and deliver contestable connections to the UK's distribution network. The firm has expanded its service portfolio to include turnkey EV charging infrastructure and Battery Energy Storage Systems (BESS) Balance of Plant, positioning it across several structural growth verticals in UK energy transition.

The service offering spans the full project lifecycle — from feasibility studies and electrical design (including earthing, protection grading, and P28/G5/4 studies) through project management, civil works, installation, commissioning, and ongoing 24/7 operation and maintenance with emergency fault response. The company is certified to ISO 9001, ISO 14001, and ISO 45001 (certificates valid through 02/08/2026), holds Achilles B2 verification, and is a member of SELECT, Constructionline, and the British Safety Council. Revenue is generated through project-based professional services engagements as Principal Contractor or specialist subcontractor, with individual project values referenced up to approximately £2M on multi-year contracts.

MES targets four primary customer segments: commercial and industrial clients requiring HV/LV distribution infrastructure; residential developers (e.g., Barratt Homes) needing contestable utility connections; renewable energy developers (e.g., Equinor UK Ltd, EnergieKontor UK) requiring grid connections and balance of plant for wind farms; and EV charging infrastructure clients, most notably SSE Enterprise under a nationwide framework agreement. The firm operates from offices in Aberdeenshire and Crawley, serving clients throughout the UK via direct enterprise sales and tender-based engagement.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• McNicholas Construction: UK utility infrastructure contractor delivering HV cable laying, substation and grid connection services for major DNOs and developers — directly comparable offering to MES' power engineering and contestable connection services, but at broader incumbent scale.
• Clancy Group: UK utility and infrastructure contractor with significant HV cable, substation and contestable connection capabilities for DNOs/IDNOs — overlapping service portfolio with MES but operating at much larger scale nationally.
• Morrison Energy Services: Major UK utility infrastructure contractor delivering HV cable installation, substation builds, and connections for DNOs and renewable developers — broad incumbent serving the same customer base as MES across DNO frameworks.
• Kirby Group Engineering (UK): International MEP and HV engineering contractor with UK operations delivering substation, grid connection and large industrial electrical projects — overlaps with MES' ICP and power engineering services but operates at much larger enterprise scale.
• Balfour Beatty (Power Transmission & Distribution): Global infrastructure group with UK Power Transmission & Distribution business delivering substations, cable systems and grid connections at utility scale — broad incumbent competitor for the largest framework opportunities where MES' principal-contractor ceiling applies.

Emerging players

• Envevo (formerly RES/Hibsco HV): UK HV connections and ICP specialist focused on renewable energy and BESS balance-of-plant — direct overlap with MES' renewable/BESS connection work, particularly the balance-of-plant and grid integration services MES delivers for sites like Sorbie and Brotherton wind farms.
• Elite Electrical Contractors: UK ICP and HV electrical contractor offering contestable connections, cable jointing and substation services — closely comparable mid-sized peer to MES, similar ICP accreditation and project profile.

Direct peers

• Freedom (NG Bailey Group): One of the UK's largest ICPs and HV infrastructure contractors, delivering contestable connections, substations and BESS balance-of-plant — competes head-to-head with MES for DNO/IDNO and renewable developer work, but at materially larger scale.
• Smith Brothers (HV Switchgear Services): UK-based high voltage electrical contractor offering HV connections, substation installation, cable jointing and ICP services for DNOs/IDNOs and renewable developers — direct overlap with MES' core service lines across 11kV–132kV.
• Powertecnique: UK specialist HV electrical contractor and ICP offering cable jointing, substation design, installation, testing and commissioning — closely comparable mid-sized peer to MES with similar ICP accreditation profile.
