Why Choose Big Green Solar?
Wales’ Solar Experts, Backed by LMG
Choosing a solar installer is a long-term decision. Your panels will sit on your roof for 25 years or more, and your battery will manage your home’s energy every single day – so it matters who you trust with the work.
Big Green Solar is the dedicated solar PV and battery storage division of LMG Home Improvements Ltd, an established building and energy-efficiency contractor based in Baglan, Port Talbot. LMG has spent years improving homes across Wales and the West, from external wall insulation and roofing to extensions and full renovations. We created Big Green Solar to give solar and battery storage the focused attention they deserve, without losing the strength of the business behind it.
Our engineers have been installing solar since the early days of the UK market, with over 1,000 installations completed. Every system is designed and installed through MCS-certified processes, and we’re TrustMark registered and HIES members, so you’re protected from the first visit to the final handover.
What really sets us apart is what sits beneath the panels. Because we’re also roofers, builders and insulation specialists, our surveyors look at your whole home, not just which way your roof faces. We spot roof problems before the scaffold goes up, can put them right as part of the same project, and can advise on insulation that makes every unit of solar power go further.
The same team delivers solar and battery programmes for housing associations and principal contractors, so you get commercial-grade standards at domestic scale. From Pembrokeshire to Bristol (see the areas we cover here), we’re local, accountable and here for the long run.
Trusted. Proficient. Accredited.
Backed by LMG Home Improvements
Big Green Solar isn’t a pop-up solar company. We’re part of LMG Home Improvements Ltd and the wider LMG Group – an established Port Talbot contractor trusted by homeowners, housing associations and local authorities across Wales. When you choose us, you get an installer with a real track record, a permanent base and a business that will still be here when you need us.
MCS Certified, TrustMark Protected
Every installation is designed, installed and commissioned through MCS-certified processes – the standard you need to claim Smart Export Guarantee payments. We’re also TrustMark registered and members of HIES, giving you independent consumer protection and peace of mind from quote to handover.
We Know Roofs Inside Out
Solar panels are only as good as the roof they sit on. As experienced roofers, we assess your roof’s condition, structure and fixings properly at survey. If slates, tiles, fascias or gutters need attention, we can sort them in the same project – saving you a second set of scaffolding and a second set of trades.
Whole-Home Energy Thinking
With years of experience in insulation and energy-efficiency work, we look at how your home uses and loses energy, not just how much it can generate. That means honest advice on whether insulation, battery storage or a combination will give you the best return – so your solar investment works harder.
Proven at Every Scale
Our engineers have been installing solar since the early days of the UK market and have completed over 1,000 installations. We deliver multi-property solar and battery programmes for social housing providers and principal contractors, including schemes for Pobl Group and Caredig – and bring the same documentation, quality checks and attention to detail to every home.
Honest Advice, Tailored Design
No hard sell and no one-size-fits-all packages. We design each system around your roof, your usage and your budget, recommending the right panels and battery capacity for how you actually live – and we’ll tell you plainly if solar isn’t the right fit.
One Team, Start to Finish
Survey, system design, scaffolding, installation, electrical certification, commissioning and network operator (DNO) notifications are all managed by us. You deal with one accountable team throughout, with clear communication on dates and progress at every stage.
Local to Wales & the West
Based in Baglan, Port Talbot, we cover homes and businesses from Cardigan to Gloucester, including Swansea, Cardiff, Newport and Bristol. Local teams mean quicker surveys, easier aftercare and people who understand Welsh housing stock and weather.

Chris BromhamDue to winter storms and exposed location of our home . We had rain water . penetrating through outside rendering into cavity wall and causing damp patches in our home . Unsure who to call and trust to do the work needed .We decided to contact LMG. From first point of contact they swiftly got a surveyor to check out the problem he came reassured us and explained what was needed to be done . We had a quote and decided to have the work done. A date was arranged for the removal of the cavity wall insulation .The work was completed in a day as the quote said .The workmen explained what they needed to do they put down protection on floor set up they were friendly professional and got on with the work in hand. Any mess was cleaned up at the end of day. The drill holes made for the extraction process of the insulation were filled and bricks taken out for the vac extraction were replaced with air bricks.
