10 Best Electricians in Swansea for 2026

Swansea's housing stock is a genuine mix, and that shapes the kind of electrical work that comes up most often here. You've got Victorian and Edwardian terraces across Brynmill, Uplands, and St Thomas that frequently need full rewires, given their age and the original single-skin brick construction that makes chasing cables trickier than in newer builds. Then there are the post-war semis and council-built estates across Sketty, Llansamlet, and Bonymaen, many of which still have older consumer units that don't meet current BS 7671 wiring regulations. Closer to the Marina and in newer developments around SA1, you're more likely to see EV charger installations, smart lighting, and solar battery storage work. Coastal exposure is worth mentioning too. Properties in Mumbles, Gower, and the Swansea Bay frontage can see accelerated corrosion on outdoor fittings and garden circuits, so any external electrical work in those areas needs fittings rated for salt-laden air.

Every business listed on this page was drawn from third-party business listings and ranked by public review rating and review count, with a small lift applied to businesses that have a working website and phone number. We read each business's homepage to confirm that electrical work is what they primarily offer, which is how unrelated trades get filtered out before the list is published. Any listing flagged as permanently closed is removed automatically. Where you see a Trust Verified badge on a business, that means they've gone further and passed our full independent verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. You can see exactly what that process involves on our How We Verify page. Businesses without that badge have not been independently verified by us, and you should carry out your own checks before booking.

Before you hire any electrician, there are a few things worth doing. Ask whether they're registered with a competent person scheme such as NICEIC, NAPIT, or ELECSA, as registration with one of these bodies means they can self-certify notifiable work without you needing to involve building control. For any new circuits, consumer unit replacements, or full rewires, you're entitled to an Electrical Installation Certificate on completion, so confirm that upfront. For an EICR on a rental property, check the electrician understands current landlord obligations in Wales, which differ slightly from England. It's worth getting at least two or three quotes for bigger jobs, partly for price comparison and partly because a good electrician will often spot things during a quote visit that others miss. Agree the scope of work in writing before anything starts.
