Save up to £1,300 a year with solar, battery and a smart tariff
Switch to solar and battery storage in three simple steps
STEP 1
Tell us about your home
Answer a few quick questions about your property, your energy use and what you’re looking to achieve. No commitment. No sales pitch.
STEP 2
We design the right system for you
Using satellite imagery and energy modelling software, we design a system around your roof, your usage and your budget before we even visit your home. That means fewer appointments, less disruption, and a quote you can trust from day one.
STEP 3
Professional installation, start to finish
Our MCS-accredited team handles everything from scaffolding to DNO notification. Most installs are complete in a day.

From your first enquiry to a working system, we work at pace to fulfil your order, with most installations only taking 1 day to install.
Backed by a team that’s done this thousands of times
VoltFlow is built on the experience of Warmer Energy Solutions, a UK-wide installer with over 26,000 multi-measure installations completed for large landlords covering solar PV, heat pumps, insulation and battery storage. The same engineers, the same compliance standards, the same aftercare.
We carry ISO 9001, ISO 14001 and ISO 45001 accreditations, and hold Gas Safe, MCS, TrustMark, Green Deal, SafeContractor SSIP, ConstructionLine Gold and RECC registrations.
VoltFlow may be a modern brand, but it has a serious track record behind it.
Trusted reviews, proven results
Your solar quote is modelled before we visit
We use Reonic — a professional solar design platform — to model your roof from satellite imagery, simulate your energy production hour by hour and calculate your expected savings before we step through your door.
That means you get an accurate quote faster, with fewer site visits and less time wasted. You’ll see exactly how many panels fit your roof, how much energy they’ll produce each month, and what that means for your bills. With everything based on your actual home, not a generic estimate.

Discover the right solar system without any hassle
You shouldn’t have to vet five companies and compare six quotes just to get solar panels on your roof. So we’ve done the legwork on the products, the installation method and the design for you. All you have to do is get in touch.
Every system we recommend is built around your home. We consider your roof size and orientation, your electricity usage, your budget and what you want the system to do for you in five, ten and twenty years’ time.
We handle the hard work. You stay in control.
We manage the quoting, the design and the coordination. You make the decisions. We do the running around.
Lower bills from the start
A properly designed system pays for itself. We’ll show you the numbers before you commit to anything.
Cut your electricity costs with solar and smart export guarantee
Your panels generate electricity during the day. A battery stores what you don’t use immediately. In the evening, your home runs on stored energy instead of drawing from the grid. Any surplus gets exported under the Smart Export Guarantee.
On a standard SEG tariff with Octopus Energy, that’s 4.1p per kWh exported. If you have a battery and want to earn more, Octopus Outgoing pays 12p per kWh, or you can opt for Agile Outgoing, which matches half-hourly wholesale rates so you sell stored energy when grid demand (and price) is highest.
Most households start seeing real savings in the first year, with bigger returns as grid prices continue to rise.
We choose products, not sponsors
VoltFlow is tech-agnostic. We don’t have a single supplier deal that locks us into recommending the same kit for every home. Instead, we work across the market to offer the right combination of panels, batteries and inverters for each installation.
Here is some of our favourite kit at the moment:
Aiko solar panels
Aiko manufactures high-efficiency N-type solar panels using ABC (All Back Contact) cell technology. Their Neostar 3S range delivers up to 23.8% module efficiency, meaning more energy per square metre and fewer panels needed on your roof. All-black aesthetics as standard.
Sigenergy SigenStor
Sigenergy’s SigenStor is a modular home energy system that brings solar inverter, battery storage, EV charging and smart energy management into one stack. The big advantage is flexibility. You can start with the system you need today, then add more battery storage or EV charging capability later without starting again from scratch.
AlphaESS Battery Storage
AlphaESS produces modular home battery systems that scale from 5kWh upwards. If your energy needs change, say you add an EV or a heat pump, the battery can grow with you.
MCS Certification
MCS certification is the UK government-backed quality standard for renewable energy installations. Every VoltFlow install is MCS-certified.
How we choose what goes on your roof and wall
We test and evaluate every product we recommend across six criteria before it makes our approved list: performance, longevity, interoperability with other systems, future-proofing, ease of use for the homeowner, and price. If a product scores well on efficiency but poorly on long-term reliability, it doesn’t make the cut.
That’s why we carry multiple panel types, including options with built-in microinverters for homes with partial shading, and all-black panels for customers who care about how the array looks. And it’s why we offer more than one battery brand, so we can match the storage solution to how you actually want to use your energy.
Every system is bespoke. We don’t sell packages. We design for your home.
Let trusted solar show you the way
VoltFlow exists to take the confusion out of home energy. The pricing, the technology, the installation, we handle it all so you don’t have to.
If you’ve been thinking about solar, a battery, an EV charger or a heat pump, the first step is a conversation. No obligation. No sales script.
