A Local Welsh Team Helping Homes Use Energy Better
We install renewable energy systems across South, Mid and West Wales with honest advice, tidy workmanship and long-term support.
Renewable Energy Installers Based in Wales
Celtic Green Energie is a Welsh renewable energy company working with homeowners who want practical ways to reduce reliance on traditional energy, improve comfort and plan for a more electric home.
We help with solar panels, battery storage, heat pumps, home air conditioning and EV chargers. The advice starts with the property, the people living in it and what they want the system to do.
You’ll speak to a real team, not a call centre. We’ll tell you what is suitable, what needs checking and what probably is not worth doing yet.
Joined-Up Home Energy Advice
Every home is different, so we look at the whole picture before recommending a system.
Solar Panels
Roof-mounted solar PV systems designed around your home, roof space and electricity use.
Battery Storage
Home batteries to store more of your generated energy and use it when it matters most.
Heat Pumps
Air source heat pump advice and installation for suitable Welsh homes.
Home Air Conditioning
Wall mounted systems for room-by-room cooling and useful winter heating.
EV Chargers
Reliable home charging installations for electric vehicle owners.
Servicing & Support
Ongoing support for renewable energy systems so they keep working as they should.
Covering South, Mid and West Wales
We regularly work with homeowners across Swansea, Neath, Llanelli, Carmarthen, Cardiff and surrounding Welsh communities.
Local knowledge matters. Access, weather exposure, older properties, rural heating, roof layout and day-to-day energy use all shape the right advice.
Practical Advice, Clean Installation, Proper Aftercare
We want customers to understand what is being installed, why it is suitable and how to use it well.
Listen First
We ask about your home, your bills, your comfort issues and what you want to achieve.
Check the Property
We look at access, roof space, heating setup, electrics and likely installation routes.
Explain the Options
You get clear recommendations without pressure or exaggerated claims.
Install Neatly
Our team works carefully in your home and explains how the system works before leaving.
