II · Our heritage

Rooted in Isca. Powering Caerleon & Newport today.

"Isca was the Roman fortress on the Usk — the great garrison of the Second Augustan Legion, in the land of the Silures."

Our name is no accident. Isca is the Roman name for Caerleon, one of Britain's most important legionary fortresses for nearly three centuries. It's where our roots are — and we're proud to carry that name across every job we do.

Two thousand years on, we're keeping the same streets, homes and businesses powered — with the craft, reliability and pride the name deserves.

How much does a house rewire cost in Newport?
Most domestic rewires in Newport and South Wales fall between £3,000 and £6,000 depending on the size of the property, access, and whether you want extras like additional sockets or a new consumer unit. We always provide a clear, fixed quote before any work starts — no hidden costs.
Do I legally need an EICR as a landlord?
Yes. In Wales, private landlords must have a valid Electrical Installation Condition Report (EICR) carried out at least every five years by a qualified electrician, and provide a copy to tenants. We carry out landlord EICRs across Newport and South Wales and can set up a recurring reminder so you never fall out of compliance.
How long does an EV charger installation take?
A standard home EV charge point is usually installed in 3–4 hours. We carry out a load assessment first to make sure your supply can handle it, fit the unit, and certify the installation to OZEV standards on the same visit.
Are you NAPIT approved and insured?
Yes — Isca Energy SW Ltd is a NAPIT-approved electrical contractor and fully insured with public liability cover. All notifiable work is certified and registered under Part P, giving you proper documentation for your records or a future property sale.
Which areas do you cover?
We're based in the heart of South Wales and cover Newport, Caerleon, Cwmbran, Pontypool, Caerphilly, Cardiff, Risca, Blackwood, Usk, Abergavenny, Chepstow, Caldicot, Magor, Rogerstone, Bassaleg and Tredegar. If you're unsure whether we reach you, just ask.
Do you offer emergency callouts?
Yes. We aim to respond to electrical emergencies within 24 hours, and often much faster. For urgent faults — loss of power, tripping circuits or anything that feels unsafe — message us on WhatsApp or call and we'll get to you as quickly as we can.
