About HCS
One contractor for every part of your home's energy system.
HCS Renewables is a family-run installer based in the UK, working with homeowners, architects and small commercial clients on integrated low-carbon energy projects. We design, install and maintain everything from rooftop solar to whole-home heat pump retrofits — all by one in-house team.
How we work
Designed by engineers, not salespeople.
Every project starts with a proper site survey and heat-loss or yield calculation. We won't quote until we've understood the building. That means fewer surprises, accurate paybacks and systems that actually perform the way the spec sheet promises.
Once installed, we stay involved — remote monitoring, annual servicing and a single number to call. No subcontracted aftercare.
