    The kit that turns a house into a power station.

    We supply the renewables hardware we install ourselves: solar panels, hybrid inverters, lithium home batteries, EV diverters, immersion controllers and the smart-home brains that tie them together. Every part is specified against the rest of the house — not pulled off a shelf because it's marked up well.

    Asked
    often.

    What brands do you stock and integrate?+

    Solar: JA Solar, Trina, Aiko, REC. Inverters: GivEnergy, Sunsynk, Fox ESS, Solis. Batteries: Pylontech, GivEnergy, Fox ESS, Tesla Powerwall. Diverters: MyEnergi Zappi & Eddi.

    Can you supply equipment without installing?+

    Yes for hardware that doesn't connect to the consumer unit. AC-side works must be done by a competent person — we can refer or quote the install separately.

    Do you do off-grid?+

    We do — usually for outbuildings, agricultural sites, and stables. Sized properly against winter generation, with a sensible backup plan.

    Will the kit pay back?+

    We model payback against your actual usage in every quote. Honest figures, not best-case marketing. Typical Wiltshire solar + battery paybacks currently sit between 7 and 11 years.

    The questions we get asked most.

    And a few that come up often enough that they may as well be here.

    We respond to enquiries as quickly as we can. When we can book routine work depends on our workload and what the job needs. For genuinely urgent problems, such as power loss, circuits that keep tripping or anything that looks unsafe, we offer urgent call-outs where possible. Phone us and we'll be honest about when we can get to you.

    We provide quotations for planned work. If we need to visit the site solely to quote, we'll confirm in advance whether that visit is free. Diagnostic visits, fault-finding and call-outs are chargeable, and we explain any fees clearly.

    Yes. Call-outs, diagnostic visits and fault-finding are chargeable, and all applicable fees are explained clearly.

    Monday to Friday, 8am to 5pm. Urgent call-outs for electrical faults, power loss, tripping circuits and other potentially unsafe issues are available where possible.

    We're based at 30 Commercial Road in Swindon and work across the town, including Old Town, Stratton and Wroughton, as well as Royal Wootton Bassett, Cirencester, Chippenham and Calne.

    Inspection and testing keep your electrical installation safe. It uncovers latent faults that, left alone, can cause fires, shocks and equipment damage. Regular reports also prevent unexpected breakdowns and the costlier repairs that follow them.

    Owner-occupied homes: at least every 10 years. Rented dwellings: every 5 years. Commercial premises: every 5 years, industrial every 3. Specialist installations such as pools, agricultural buildings and marinas need shorter cycles. We'll tell you straight which band you're in.

    You receive an EICR, an Electrical Installation Condition Report. It records the condition of every circuit, classified C1, C2, C3 or FI. If anything is flagged, you get a quoted remedial plan with it. Plain English, no surprises.

    £5m public liability, full professional indemnity, and the certifications to back it. Copies of all policies are issued with every quote on request.
