What Last Mile does

Last Mile Infrastructure Group Limited is a UK-based multi-utility infrastructure provider that designs, builds, owns and operates the 'last mile' connections linking new residential, commercial and industrial developments to electricity, gas, water, wastewater, heat and fibre networks. Founded in 2002 as the first Independent Distribution Network Operator (IDNO) licence holder in Great Britain, the company has grown to 800+ employees operating from eight regional offices across Scotland, England and Wales. It serves major housebuilders (Barratt Redrow, Taylor Wimpey, Wain Homes, Cruden Homes, Buckland Development), strategic site developers (Urban & Civic, Harworth Group), industrial and logistics operators (Indurent, McAleer & Rushe), EV charging operators (Moto Hospitality, GRIDSERVE), and infrastructure partners (National Highways, Homes England, Portsmouth Water).

The company's core technology stack rests on a portfolio of scarce UK utility licences — Ofgem IDNO and IGT licences for electricity and gas, Ofwat NAV licences for water and wastewater, and Ofgem-regulated heat network operation — combined with proprietary 5th generation ambient heat network technology. Notable technical assets include the UK's first water-source ambient heat network at Welborne Garden Village (drawing stable-temperature energy from Portsmouth Water's Hoads Hill Reservoir), Scotland's first ambient heat network at Barnton, directional drilling capability beneath major motorways (M4 junction 17), and high-capacity substation delivery up to 22 MVA across 26 substations at Waterbeach. Last Mile Asset Management operates the long-term regulated ownership of these networks with 24/7 monitoring, billing and emergency response. The asset management portal (lastmile-uk.com) supports competitive asset valuations and adoption processing for ICPs, EV charging developers and clean energy organisations.

Last Mile generates revenue through three primary streams: one-time fees for multi-utility connection design and build services; recurring, regulated revenue from long-term network ownership and operation as IDNO/IGT/NAV/heat network operator; and transaction-based asset adoption payments to Independent Connection Providers and EV charging developers. The forward-funded heat network model — where Last Mile funds capital costs in exchange for long-term network ownership — represents an innovative pricing structure that has delivered up to 60% developer capex savings (e.g., Barnton). Pricing is project-specific and negotiated through regional business development managers. As of April 2026, the company had surpassed 1 million cumulative utility connections with a contracted pipeline of approximately 710,000 additional connections. The company became wholly owned by Macquarie Asset Management in May 2026, following acquisition of the remaining stake previously held by Infracapital.

Revenue model

1. Multi-utility connection design and build services: One-time fees for designing and constructing multi-utility infrastructure (electricity, gas, water, wastewater, heat networks) for new residential, commercial, and industrial developments. Services include new connections, substations, off-site works, and NAV licensing for water and wastewater.
2. Network ownership and long-term management: Recurring revenue from owning and operating utility networks long-term after adoption. Last Mile Asset Management adopts electricity, gas, water, wastewater and heat networks, providing 24/7 monitoring, maintenance, billing management and customer support. Networks are managed through Ofgem-regulated IDNO/IGT companies and Ofwat-regulated NAV.
3. Asset adoption valuations and payments: Last Mile Asset Management provides competitive asset valuations to ICPs, EV charging developers and clean energy organisations, paying for the right to adopt newly constructed networks. Value agreements reduce developers' capital expenditure through asset value rebates upon energisation.
4. NAV (New Appointment and Variation) licensing: Last Mile Water operates as a licensed NAV (New Appointments and Variations) for clean water and wastewater, serving as an alternative to incumbent water companies. Provides developers with cost savings through shared trenching, flexibility, speedier decision-making, and reduced connection times — approximately 25-50% faster delivery per Ofwat research.

Core offering

Last Mile Infrastructure Group Limited designs, builds, owns and operates multi-utility last mile infrastructure connecting new residential, commercial, industrial and mixed-use developments across Great Britain to essential networks covering electricity (as an IDNO), gas (as an IGT), water and wastewater (as a NAV), and low-carbon heat networks (as an Ofgem-regulated heat network operator). The company also provides long-term network ownership, operation, maintenance and asset adoption services via Last Mile Asset Management, and forward-funded heat network solutions to remove developer capital burden.
