What we do
How it works
A 30-min call to understand your home, your bills, and what matters to you. No doorstep sales. No pressure. Just a real conversation.
Our engineers design a system tailored to your roof and your usage. We send you a transparent, itemised proposal — no guesswork.
An MCS engineer visits to finalise the design. Then our in-house team installs — typically in a single day. No subcontractors.
We register with the DNO, set up your monitoring app, and walk you through SEG export. Your install is covered by a 25-year product & workmanship warranty.

Your mortgage lender
Some pay cashback after install. Some lend at 0% interest. Some give you a better mortgage rate for an already-green home. Pick yours and we'll show you what's possible.
Your lender isn't here, or you're not sure?
Tell us your lender and we'll look into itGeko Energy is not a mortgage adviser. Information about lender products is factual and sourced from each lender's own published pages, verified on 23 June 2026. Always confirm current terms direct with your lender before relying on any specific figure. Eligibility is determined by your lender.

This is the work. Real UK homes, fitted by our own team — every week, all year.
Protection promise
Solar is a 25-year commitment to your home. Every Geko install comes with the certifications, insurance and warranties that mean you're still covered long after the panels are switched on.
Every system is designed, installed and commissioned by Geko's own engineers — working to MCS standards, with our MCS certification audit currently in progress via the IAA. No subcontractors.
Our own labour warranty in writing — covering wiring, mounting, weatherproofing and commissioning. Five times the MCS minimum.
Tier-1 panels (DMEG, Aiko) carry 25-year manufacturer warranties. Inverters 10–12yrs. Batteries 10yrs. All in writing.
Our workmanship warranty is underwritten through NICEIC's Insurance-Backed Guarantee scheme — so your install stays protected even in the unlikely event Geko ceased trading. Cover is provided by FCA-regulated insurers.
Full public liability and £5m professional indemnity insurance on every install. Cover certificates available on request.
If we ever can't resolve a complaint between us, our IAA membership and Citizens Advice provide independent routes — free to you, binding on us. See our complaints policy for the full escalation path.
Not optional add-ons. Not premium tiers. Every Geko install ships with the lot.
What our customers say
“I cannot fault Geko — top-tier service from start to finish”
I cannot fault Geko, if only all installers worked this way. They just get it right — you feel like you're dealing with people who know their stuff. Solar and battery install without a single issue.
“Excellent service from start to finish!”
The entire process was smooth, well-coordinated, and clearly communicated throughout. The Geko engineer who designed our system was incredibly helpful and responsive. Really pleased with the outcome.
“Professional from start to finish”
I got three quotes and GEKO came in the most competitive without feeling cheap. Ethan was honest about what we did and didn't need — he actually talked us out of a bigger battery than necessary. Neil and the install crew arrived 8am sharp, were tidy, polite, and finished by 3pm. App was up and running before they left.
“Three weeks from enquiry to running”
Honestly the speed surprised me. Harry did the initial quote on a Tuesday, surveyor came the following Monday, scaffolding up two weeks later and David fitted the lot the day after that. 14 AIKO panels and a FoxESS inverter. No mess, no fuss, no hard sell.
“From over £3,000 a year to £23 a month”
16 panels, a 12kWh Fox battery, installed in a single day — Pete & Sarah's electricity bill dropped from over £3,000 a year to just £23 a month. Around a 92% reduction.
