Electrical Solutions We Offer

Residential
Cardiff households get the full range: rewiring, switchboard and RCD replacements, LED lights, ceiling fans, more outlets, power to garages and sheds, outdoor lights, plus separate circuits for air con and big appliances.

Commercial
In the Cardiff industrial estate we install and fault-find three phase, wire machinery and compressors, fit high bay and workshop lights, upgrade switchboards, check emergency and exit lights, do test and tag, and run planned maintenance.
Workshop, Warehouse And Home Electrical In Cardiff
Cardiff pairs a substantial trade and industrial estate with rows of family housing. A workshop needing three phase for a hoist and a young family needing extra points for a nursery are both normal Tuesdays for us.
What does not change is the approach: measure the real load, quote the real job, and never sell you capacity you will not use.
Over 40 Years of Combined Experience
Over 40 years of combined experience spanning homes, shops and light industrial sites, the exact mix Cardiff calls for. Workshop machinery and family houses each get a licensed specialist.
Reliable and Punctual
Downtime in a workshop costs you money, so Cardiff commercial work is tightly scheduled with clear updates. Home customers get a proper arrival time, not just 'sometime this morning'.
Quality Work
Correctly sized submains and properly rated protection for machinery, compressors and hoists. Undersizing a workshop circuit is one of the most common and most dangerous shortcuts we see.
Safety and Transparency
Full testing, certification and clear labelling on every installation. Commercial clients get documentation ready for insurers and auditors without needing to ask twice.
Emergency Services
Cardiff emergencies take priority during business hours. Whether a workshop has lost power or a home switchboard refuses to reset, it goes to the top of the job sheet and is made safe on arrival.
Trustworthy Electricians
Fully licensed, fully insured and steady on site. We do site inductions, follow your safety rules, keep our work zone contained, and leave workshops and homes clean.
How Our Residential Electrician Works



Consultation
Ring us with details of the equipment or the fault. For workshops we ask about machine ratings and duty cycles from the start, so your quote matches the true electrical load.


Visit Your Home
On site we take real load readings and inspect the existing submains and protection. The quote you receive is fixed and spells out cable sizes, protection devices and labour, with no hidden extras.


Electrical Work
Once approved, everything is wired with properly rated materials and complies fully with AS/NZS 3000. Busy workshops get the job staged, with any shutdown planned alongside you to keep lost production low.


Quality Check
We test each circuit under load, label it and record the results. Along with your Certificate of Compliance, commercial clients get the complete test records for their compliance files.

Frequently Asked Questions
How Much Do Electricians Cost In Cardiff?
What's Your Approach To Managing Unexpected Problems In The Electrical Project?
In Cardiff workshops, the issue we see most is submains or protection sized for the first machine on site and now well short of what the current equipment draws.
Anything unsafe gets isolated there and then. Next we explain the load calculation and the fix, send a revised quote, and hold off on extra work until you sign off.
