About David
David Coleman is the founder of kilowatts.uk, a UK platform connecting homeowners and businesses with reviewed renewable energy installers. He built the platform from the ground up with a focus on transparency, installer quality, and helping people make genuinely informed decisions about solar panels, battery storage, heat pumps, and wind power.
David has spent years working closely with installers, DNOs, and homeowners across the UK, developing a practical understanding of how renewable energy systems are designed, specified, and installed in real conditions, not just on paper. That hands-on perspective shapes every piece of content published on kilowatts.uk.
Why kilowatts.uk Exists
The renewable energy market in the UK moves fast. Grant schemes change, hardware costs shift, and installer quality varies significantly. David started kilowatts.uk because he saw too many homeowners making expensive decisions based on incomplete information, or ending up with poorly designed systems because they had no reliable way to compare installers.
The platform vets every installer it works with and publishes independent guides based on real installation data, not manufacturer specs or sponsored content. The goal is simple: give people the information they actually need, then connect them with someone qualified to do the work properly.
Areas of Expertise
☀️ Solar Panel Systems
System sizing, panel selection, G98/G99 grid connection, generation modelling, and installer quality assessment across residential, commercial, and industrial installations.
🔋 Battery Storage
AC and DC coupling, time-of-use tariff optimisation, backup power configurations, and whole-system design for solar-plus-storage installations.
♨️ Heat Pumps
Air source and ground source systems, hydronic design for low-temperature operation, MCS certification requirements, and the Boiler Upgrade Scheme grant process.
📋 UK Energy Policy
BUS grant rules, ECO4, Smart Export Guarantee rates, permitted development rights, and how government energy policy affects real installation decisions.
🌬️ Wind Power
Micro and large-scale turbine selection, site wind resource assessment, permitted development limits, G98/G99 grid connection for wind, and planning considerations for residential and commercial installations.
⚡ EV & Smart Energy
Home EV charger selection, OZEV grant eligibility, smart tariff optimisation, time-of-use load shifting, and integrating EV charging with solar and battery systems.
The Vision
David's ambition for kilowatts.uk is to become the UK's number one authority in renewable energy aggregation, the place homeowners, businesses, and installers turn to first when making decisions about clean energy technology.
That means going beyond a simple installer directory. The platform is being built to connect every part of the renewable energy supply chain: from consumer education and installer vetting, through to project management, hardware comparison, and post-installation support. The goal is to make the entire process, from first question to working system, simpler, more transparent, and better value than anything currently available.
Longer term, kilowatts.uk is designed as a technology aggregation platform, not a single-sector product. Renewable energy is the focus today because the need is urgent and the market is underserved. But the underlying platform is being built with the flexibility to expand into adjacent technology sectors as they mature, because the same problems of installer quality, consumer trust, and market transparency exist wherever complex technology meets everyday people.
Editorial Standards
Content on kilowatts.uk is written or reviewed by David and draws on installation data tracked across the platform, published Ofgem guidance, DESNZ statistics, and direct input from renewable-energy installers.
