Two ways to work with us
Electrical Installations
General electrical work for domestic and commercial clients, handled by our electrical specialists. Book an appointment, or request an estimate first if you'd rather know the cost before committing.

Faults, dangerous wiring, total loss of power — if it can't wait until normal hours, call us directly rather than booking online.
Engineered around your data — not sold off a shelf
Most of the renewable energy industry is run by salespeople, not engineers. Systems get sized by rule of thumb, batteries get oversold, and nobody checks whether the local network can actually take the connection. We do it differently.
30 days of real usage data
Before we design anything, we fit a data logger and track your actual usage, timing and values for a full 30 days — so your system is sized to how you really live or operate.
Sized for your load, not the grid
No oversized batteries you'll never fill, and no systems designed simply to export. Every design targets your actual demand first.
Checked against network capacity
We factor in your local electrical supply operator's individual requirements, capacity and suitability — so what we design can actually be connected.
Engineer-led, no sales staff
Every design comes from a experienced, qualified engineer's assessment of your property and data — never a target you're sold up to.
No oversell, no underachieve
We won't design a system that underdelivers for you — just a transparent, economical solution sized to your real, modern energy demand.
Built for when you actually need power
With EV uptake rising and energy costs climbing, generating during the day isn't enough on its own. A well-designed PV and battery system stores what you generate so it's there when you need it — charging your EV overnight, or getting you through peak-rate hours — not just while the sun's out.
A straightforward path — no pressure, no surprises
Most firms push you straight to a sales pitch. We start with an honest, free look at your property first.
Free initial assessment
Book online in a couple of minutes. We review your property and energy usage remotely — completely free, no obligation.
Speak with an expert
We'll call or WhatsApp you to talk through what's possible. If you'd like to go further, we'll arrange a 30-day data logging period and a full technical design built entirely around your real usage.
Full installation
Once you're happy with the design, our experienced, qualified engineers carry out a full, certified installation — on time, on budget, and fully signed off.
Right first time, properly documented
Good engineering isn't just what happens on the day of installation — it's a process, followed consistently, that gets the design right before work begins and leaves you with a system that's tested, documented and fully compliant.
Right first time
A rigorous design and quality management process means the plan is right before anyone picks up a tool — fewer surprises, fewer callbacks, no cut corners.
Fully tested
Every installation is tested on completion to confirm it performs as designed, not just that it's switched on.
Fully documented & certificated
You're handed proper documentation and certification for every job — not a verbal assurance, a paper trail you can rely on.
Correct DNO applications
Where a connection requires it, we submit the correct application to your local Distribution Network Operator on your behalf, so your system is properly approved, not just installed.
Peace of mind, built in
The relationship doesn't end at handover. Every renewable energy install is backed and, if you choose, actively looked after.
Fully managed & remotely monitored
Opt in to a fully managed service and we'll keep watch on your system remotely — tracking performance and health so issues are caught before they become downtime.
10-year parts & labour warranty
Every installation is covered for a full 10 years — parts and labour — so you're never left facing an unexpected bill if something needs attention.
Domestic, commercial & industrial
The same engineering-led approach, scaled to fit — from a single home to a full industrial site.
Domestic
Bespoke systems designed around how your household actually uses energy.
Commercial
Systems engineered to cut operating costs without disrupting your business.
Industrial
Large-scale installations, engineered with your network capacity and load in mind from day one.
A different kind of electrical & renewable energy company
JF Power & Renewables was founded to do electrical and renewable energy work differently — starting with engineering, not a sales pitch. We cover general electrical installation work — power & lighting, CCTV, data & networking, AV, fire alarms, EICR reports and PAT testing — alongside photovoltaic (PV), battery storage and EV charging systems, for domestic, commercial and industrial clients, with no sales staff on the team. Every project is led by our own engineers.
We take pride in high-quality, high-integrity, bespoke-designed systems, and every installation is carried out by a experienced, qualified engineer.

Common questions
What happens during the free assessment?
We review your property and current energy usage remotely, then talk you through what's possible over a call or WhatsApp — free, no obligation, and no sales pressure.
How long does an installation take?
Most domestic installations are completed within a day or two. Commercial and industrial projects vary with scale — we'll give you a clear timeframe as part of your fixed quote.
Is my roof or site suitable?
Suitability depends on orientation, pitch, shading and structural condition — something we assess for free before recommending anything. Most properties can support a system; the right design just varies.
Do you offer payment plans?
We can talk through payment options as part of your free assessment — get in touch to find out what's available for your project.
Are there any UK incentives for solar or battery storage?
Most residential installations currently qualify for 0% VAT, and the Smart Export Guarantee can pay you for electricity you export. See our guide to UK solar incentives for details.
