FUNDED ENERGY SOLUTIONS LIMITED

What FUNDED ENERGY SOLUTIONS LIMITED does

Funded Energy Solutions Limited is a UK-based private limited company that invents, manufactures and directly installs six proprietary energy-saving technologies targeting HVAC-R systems: Inject-a-Therm and Inject-a-Cool (water-system additives improving thermal transfer), DBMU (dynamic burner/compressor control), Warm Air Control (demand-driven warm air management), DHC (residential housing control) and RCU (refrigeration control). All six products are underpinned by the Adaptive Optimisation Platform, a proprietary control system that ingests structured time-series sensor data, continuously learns process behaviour, predicts future demand, delays unnecessary energy input and auto-reverts when operating limits are approached. The company has accumulated over 10,000 installations across the UK and holds WRAS approval on the water-system additives and qualified ESOS Lead Assessor status from BEIS, which it leverages as both a compliance credential and a sales channel.

The business operates a direct sales-and-installation model supplemented by a growing partner network of energy consultants, M&E contractors, facilities management companies and HVAC engineers, with exclusive-territory options available to qualifying partners. Pricing is quote-based and project-specific, with no public tariff; a freemium-style entry point (free energy assessment and personalised welcome pack) is used to convert top-of-funnel interest. Revenue mechanics combine one-time product/licence sales with in-house installation services. The addressable customer base is broad and segmented by vertical: hotels and hospitality, catering and food services, industrial and manufacturing, data centres and cleanrooms, residential, warehouses and distribution, and the public sector (including schools). Free online calculators and an affiliation with the 'What's the Payback' energy consultancy platform extend the surface beyond hardware into ESOS compliance, carbon reporting, SECR and savings tracking.

Ownership is private and founder-led, with Ian Douglas identified as the primary contact. The company is a trading entity under the parent Funded Energy Solutions Ltd, incorporated in England and Wales. No institutional investment, funding rounds, or public-shareholder structure is disclosed. Operations are UK-only and the company explicitly manufactures and installs only its own products in order to retain control over quality and performance.

Core offering

Funded Energy Solutions designs, manufactures and installs six proprietary energy-saving technologies targeting HVAC-R inefficiencies in commercial and residential buildings: heating and chilled water additives (Inject-a-Therm, Inject-a-Cool), commercial compressor/burner controls (DBMU, Warm Air Control), domestic housing control (DHC), and refrigeration control (RCU). All products are underpinned by an Adaptive Optimisation Platform that continuously learns process behaviour and optimises energy input, with the company stating installations across more than 10,000 UK sites.

Product overview

Funded Energy Solutions is an inventor and manufacturer of six energy-saving technologies for HVAC-R systems, all underpinned by an Adaptive Optimisation Platform that continuously learns process behaviour and predicts future demand to optimize energy input. The product portfolio includes: Inject-a-Therm (heating additive improving thermal conductivity up to 22% savings), Inject-a-Cool (chilled water additive reducing cooling energy up to 25%), DBMU/Compressor Control (intelligent burner management saving 17-30% gas), Warm Air Control (demand-driven warm air management saving 20-35% gas), DHC (domestic housing control saving 20-30% across heating, hot water and electrical), and RCU (refrigeration control saving 15-25%). The company supplies and installs only what it manufactures, combining deep energy consultancy expertise with hands-on technology development as ESOS Lead Assessors.

Functional benefit

Products and services

• Inject-a-Therm Heating system additive that enhances thermal conductivity of water-based heating systems, enabling boilers to reach target temperatures faster and maintain them with less energy input; achieves up to 22% gas or oil consumption reduction and extends system life by reducing corrosion and limescale build-up. WRAS approved.
• Inject-a-Cool Chilled water additive that optimises cooling system performance by enhancing heat exchange in the chilled water loop; reduces compressor workload and delivers up to 25% cooling energy savings while protecting internal pipework from corrosion and biological growth. WRAS approved, operating range -5°C to 25°C.
• DBMU (Dynamic Burner Management Unit / Compressor Control) Intelligent commercial compressor control system that continuously monitors and adjusts burner operation in real-time, eliminating energy waste from over-firing, short-cycling and inefficient modulation; delivers 17-30% gas savings through dynamic load matching and optimised firing sequences.
• Warm Air Control Demand-driven warm air management system that replaces basic on/off thermostatic control with intelligent modulating control; reduces gas consumption in warehouses, factories and commercial spaces by 20-35% through continuous temperature monitoring and precise heating demand calculation.
• DHC (Domestic Housing Control) All-in-one residential energy management system for heating, hot water and electrical systems; uses smart learning to automatically adjust household patterns for maximum efficiency and comfort, delivering 20-30% energy bill reductions. Features touchscreen controller and smartphone app connectivity.
• RCU (Refrigeration Control) Refrigeration control system designed to optimise commercial refrigeration efficiency; part of the six-technology portfolio targeting HVAC-R energy inefficiencies, delivering 15-25% savings.
• What's the Payback? Energy Consultancy Services Energy consultancy services delivered as qualified ESOS Lead Assessors, covering ESOS compliance, carbon reporting, SECR (Streamlined Energy and Carbon Reporting), and ongoing savings tracking for UK organisations to measure, report and reduce their energy use.

• Schneider Electric (EcoStruxure): Global BMS and energy management incumbent with HVAC controls, refrigeration, and building optimisation products. Comparable to FES across the smart HVAC controls and energy-saving value proposition but addresses much larger enterprises and global accounts.
• Siemens Smart Infrastructure: Siemens division offering Desigo CC BMS, HVAC controls, and energy analytics for commercial and industrial buildings. Competes in the same UK energy-efficiency/compliance niche where FES operates, particularly around decarbonisation mandates.
• Honeywell Building Technologies: Division of Honeywell offering BMS, HVAC controls, energy management, and optimisation across commercial real estate. Overlaps with FES' Adaptive Optimisation Platform and DBMU/Warm Air Control in commercial sites, but at much larger scale and broader portfolio.
