As the capital and the biggest used-car market in South Wales, Cardiff is where more used EVs change hands than anywhere else in the region — and a high share are ex-fleet, ex-hire or ex-private-hire cars, exactly where battery condition is hardest to read from the dashboard. PAD is South Wales' only Aviloo & Generational certified mobile EV battery testing service — we come to the seller's address in Cardiff, run the test on site, and email your official certificate the same day.
Battery Management System readings can be misleading — Aviloo has found hidden cell damage in EVs showing 89% SOH on the dashboard. PAD's Aviloo FLASH test is the only TÜV-certified independent battery diagnostic available as a mobile service in South Wales. Every certified EV sells faster and for more — buyers who know their battery is verified pay with confidence.

Cardiff is where most of South Wales' used EVs actually change hands — on the forecourts along Penarth Road, out at Leckwith and Newport Road, and privately right across the city. Whichever way you're buying, the battery is the one thing you can't judge by looking at it.
A dealer's own "battery health check" is a self-assessment — they have an interest in the sale. An independent Aviloo certificate doesn't. PAD can meet you at the forecourt and test before you sign. If it's a strong number, you buy with confidence. If it's not, you've got hard, independent evidence to negotiate on rather than a gut feeling.
Private Cardiff sales through AutoTrader and Facebook Marketplace move fast — often within a day or two. PAD tests at the seller's address before any money changes hands, evenings and weekends, so a viewing doesn't have to wait for a garage appointment. The seller keeps the car; you get an independent certificate before you commit.
As the capital, Cardiff feeds a high share of ex-fleet, ex-hire and ex-private-hire EVs into the used market. Those cars can be excellent value — but they've often lived on frequent rapid-charging and high mileage, which is precisely the history that degrades a pack faster than the dashboard admits. Two cars of the same year and mileage can sit several percent apart on true state of health. An independent cell-level test is the only way to tell which one you're actually looking at.
Cardiff is roughly 20 miles from PAD's Pontypridd base, so a travel fee applies on top of the £79 test. You enter your postcode at booking and the exact fee is calculated and shown before you confirm — no surprises, no call-out charge hidden in the price.
Travel cost calculated automatically when you enter your postcode at booking. Always quoted upfront — no surprises.
Every CF postcode across the city, from the bay to the northern suburbs — Cathays, Roath, Canton, Riverside, Pontcanna, Grangetown, Splott, Adamsdown, Heath, Llandaff, Whitchurch, Rhiwbina, Lisvane, Cyncoed and Radyr.
No driveway? No problem. Much of inner Cardiff — the Victorian terraces of Cathays, Roath, Grangetown and Splott — is permit parking with no off-street space. PAD tests kerbside on the street, at the seller's address, or on a dealer's forecourt. The Aviloo test runs off the car's OBD port, so all it needs is safe access to the vehicle — not a garage, not a driveway.
