We are 8energy
We don't do one thing. We do all of it — properly, under one roof, with the right specialist on every job.
Free & no-obligation
A genuine analysis of your real data before anything is quoted or sold.
Fixed, itemised price
One price, broken down in full. Once it's issued, it doesn't move.
A specialist, not a salesperson
The person who designs your system is in your home — not a commission-only salesperson.
The full range
Every part of home energy, under one roof
Solar
Systems sized from your actual half-hourly usage, not a guess off your annual bill.
Battery storage (ESS)
Sized to match how your home really uses power, day and night.
Air source heat pumps
Proper room-by-room heat loss calculation behind every install, not a rough estimate.
EV charging
Built around how and when you actually charge.
Air conditioning
Fast, clean installs from F-Gas certified engineers.
Voltage optimisation
Protecting your home's electrics for the long run.

The free analysis
The one thing no one else in this market gives you
We read your own half-hourly electricity data and show you exactly what solar and a battery would do in your home — your real usage, and a genuine payback figure — before you commit to anything. It's free, and you don't need to come with us.

Why 8energy
Your home's energy is one system, not eight problems
Because most companies pick one thing and sell it hard. We built this to actually cover the whole picture — because your home's energy isn't eight separate problems, it's one system, and it should be designed like one.
From the blog
Straight talk on home energy
Questions, answered straight
The honest answers
Is the analysis really free — what's the catch?+
It's genuinely free and there's no catch. We read your own half-hourly electricity data and show you what solar and a battery would really do in your home — including a real payback figure. If the honest answer is that it isn't worth it for you, we'll tell you that too. You're under no obligation to go ahead with us.
Do I have to decide on the day?+
No. There's no same-day-signature pressure, ever. Once we've issued your fixed quote, the price doesn't change while you think it over — take a few days or a few weeks. We won't chase you.
How is your pricing structured?+
One fixed price, itemised in full so you can see exactly what you're paying for. Once it's issued, it doesn't move. No hidden extras, no commission-driven upsell.
Are you insured and qualified?+
Every job is covered by public liability and professional indemnity insurance, and every specialist is qualified in their own field before they're ever in your home — accredited electricians, F-Gas engineers and MCS-trained installers. Our NAPIT, MCS and IWA accreditations are in progress — we're doing it properly rather than pretending it's already done.
What areas do you cover?+
We're based in Hertfordshire and cover the surrounding areas. If you're not sure whether you're in range, ask — we'll tell you straight.
Why start with my data instead of my energy bill?+
Your annual kWh hides the one thing that decides what system you actually need: the shape of how and when you use power. Reading your half-hourly data lets us size the system to your real home, not a template or a guess off your bill.
What can you actually install?+
All of it, under one roof: solar, battery storage, air source heat pumps, air conditioning, EV charging, voltage optimisation and energy management — designed together as one system, by the specialist who'll fit it.
