Buying solar isn’t like buying a new television.
It’s one of the biggest investments you’ll make in your home.
The right system could save you thousands of pounds over the next 25 years.
The wrong one could leave you with a system that’s oversized, underperforming or simply not designed around the way your family actually uses electricity.
That’s why choosing the right installer matters just as much as choosing the right equipment.
At GJM Energy, we’ve always believed homeowners deserve something that’s becoming increasingly rare…
Honest advice before a sales pitch.
The Best Solar Companies Don’t Start With a Quote
Many homeowners contact us after already speaking to two or three national companies.
Often they’ve received completely different recommendations.
One company recommends 10 panels.
Another suggests 18.
Someone else says they must have batteries.
Another says batteries aren’t worth it.
It’s confusing.
And unfortunately, it’s also common.
Before anyone recommends equipment, they should first understand your home.
That means looking at:
- Your roof orientation.
- Shading throughout the day.
- Your annual electricity usage.
- When your household uses most of its electricity.
- Future plans such as an EV charger or heat pump.
- Your long-term goals.
Without understanding those things, no installer can confidently recommend the right solution.
Our Customers Keep Mentioning the Same Thing…
We don’t tell our customers what to write in reviews.
Yet when we read our latest Google and Trustpilot feedback, the same themes appear again and again.
“No pressure.”
“Everything was explained.”
“Much more detailed than other companies.”
“We never felt rushed.”
“The survey was incredibly thorough.”
“Highly recommended.”
Those aren’t marketing slogans.
They’re genuine comments from homeowners who wanted facts before making a decision.
We think that’s exactly how buying solar should feel.
Why We Lite to Try to Visit Your Home
Technology is brilliant.
Satellite imagery.
Remote surveys.
AI roof modelling.
They all have their place.
But nothing replaces standing outside your property.
Walking around your home.
Looking at the roof.
Understanding any shading.
Listening to how your family actually lives.
That’s why every GJM Energy quotation begins with an in-person visit.
It helps us design systems that maximise performance rather than simply maximise panel numbers.
Quality Isn’t Just About the Equipment
Many installers use excellent solar panels.
Many use excellent batteries.
The difference is often everything that happens before and after installation.
At GJM Energy, quality means:
✔ Taking the time to answer every question.
✔ Designing every system individually.
✔ Turning up when we say we will.
✔ Keeping homeowners informed throughout the installation.
✔ Installing neatly and professionally.
✔ Supporting customers long after commissioning.
It’s a complete customer experience, not simply a product.
Gavin Matthews: “Our Job Isn’t to Sell Solar. It’s to Help People Make the Right Decision.”
Owner Gavin Matthews believes education should always come before installation.
“If someone leaves our office understanding solar better than when they arrived, we’ve done our job.
Whether they choose GJM Energy or not is their decision.
We’d much rather homeowners make an informed choice than one they later regret.
That’s why we’ve built our business around education, honesty and giving people the facts.”
That philosophy has helped GJM Energy earn over 100 five-star reviews from homeowners across Bedfordshire, Hertfordshire and Buckinghamshire.
Five Questions Every Homeowner Should Ask Before Choosing a Solar Installer
Before accepting any quotation, ask:
- Will someone visit my home in person?
- Why have you recommended this system?
- Can you explain how you calculated the expected generation?
- What happens if my energy usage changes in the future?
- Can I speak to previous customers or read recent reviews?
If an installer welcomes those questions, that’s usually a very good sign.

At GJM Energy, we believe that’s how every homeowner should buy solar.
