Real questions.
Straight answers.

Not within 10 miles of Pontypridd. Travel is built into every price you see. Further out, the booking form works out a small travel fee from your postcode, so the total on screen is the total you pay. I cover most of South Wales.

Home patch is Pontypridd and RCT: Treforest, Porth, Tonypandy, Aberdare, Llantrisant, Mountain Ash, Ferndale. I also cover Cardiff, Caerphilly, Merthyr Tydfil, Bridgend, Newport and Swansea. The first 10 miles from Pontypridd are free; beyond that there’s a small mileage fee, quoted at booking before you commit to anything.

Yes, every job. Your driveway, your work, a seller's house, a dealer's forecourt. I bring everything with me and email the certificate or report before I drive off. There's no garage to visit because there is no garage.

From £79, and that includes the official Aviloo certificate, a 12V battery check and a full OBD scan. PHEVs are from £89 because there's more to test. Travel is included within 10 miles of Pontypridd; beyond that a small mileage charge is added and shown at booking. No deposit, no VAT on top.

No. Book online, I confirm, you pay on the day once the work's done. Card through Square, bank transfer or cash. And if the test can't be completed, say the vehicle turns out to be incompatible, you don't pay anything at all.

Weekday evenings 5:30pm to 9pm, Saturdays 10am to 7pm, Sundays 10am to 6pm, and yes, weekends and bank holidays are working days for PAD. The booking calendar shows live availability, so if a slot is showing, it's bookable.

You won’t usually need one. Prices are fixed and published, and the booking form shows your exact total including travel before you confirm anything. For odd jobs, fleet volumes, or a vehicle you can’t find on the list, WhatsApp me. Asking costs nothing.

Not from the dashboard, that’s the short answer. The dash figure is the car’s own estimate of itself. What you want is an independent measurement: I plug Aviloo’s kit into the car, it measures the actual State of Health, and you get a certificate any buyer, dealer or insurer can verify. From £79, and I'll happily do it on the seller's driveway before any money moves.

Aviloo is an Austrian battery diagnostics company whose tests are used by dealers and insurers across Europe. The certificate gives your battery's measured State of Health as a percentage. It's locked to the car's VIN and carries a QR code anyone can scan to confirm it's real on Aviloo's database. Signed, timestamped, and not something a seller can knock up in Photoshop.

Completely. The test reads data from the battery management system passively. It doesn't charge, discharge, stress or modify anything, so there's no risk to the battery and no effect on your manufacturer warranty. It's silent too. Most people are surprised how uneventful the whole thing looks.

Rough rules of thumb: above 90% is strong for a car under four years old, high 80s is normal for a mid-life EV, and below about 85% it's worth a conversation about the price. But age, mileage, battery chemistry and how the car was charged all move the picture, which is the honest reason rules of thumb aren't enough. The certificate gives you the real number for the actual car in front of you.

It's the car marking its own homework. The figure comes from the battery management system, which is software estimating health from its own internal data. It can drift from true capacity, and a buyer has no way to check it. An independent measurement turns the seller's word into evidence.

I book an hour; the test itself is usually done in about twenty minutes. The battery needs a reasonable amount of charge, ideally half or more. When you book, I'll confirm exactly what your model needs so there are no surprises on the day.

Over 500 EV variants across 30-plus brands, from the Nissan Leaf and Renault Zoe through to Tesla, Ioniq 5, Kia e-Niro and BMW iX, plus 73-odd plug-in hybrids. The free coverage checker gives you an instant answer from your reg. Not listed? WhatsApp me the reg anyway. Coverage grows all the time.

It varies wildly by model, but out of warranty you're into thousands: very roughly £3,000 to £5,000 for smaller packs, and well past £10,000 for the big ones. Nobody plans to replace a pack. Which is the whole argument for spending £79 to measure the most expensive part of the car before you buy it.

Honestly, usually yes. Aviloo's own remarketing research (their 2025 whitepaper) put the premium at £450 to £900 on average for certified cars, and they sell quicker, because buyers stop pricing in a battery they can't see. Every viewer asking £500 off 'for the battery' is negotiating against a certificate you don't have. The £79 usually comes back several times over.

Yes, and it’s one of my most-booked jobs. I’ll meet you at the seller’s address or the forecourt, run the checks, and you’ll have the results before any money changes hands. Send me the advert on WhatsApp first. I’ll often spot something worth asking the seller before you’ve even travelled. See pre-purchase checks.

The standard check is £45 on any vehicle: a full OBD scan across every module including cleared-code history, a 12V load test and a visual once-over, with a written report the same day. On an EV it's £79 and on a PHEV £89 with the full Aviloo certificate included. That's the same price as the standalone battery tests, so the inspection effectively comes free.

Less than you’d hope. The bars are broad bands, not a measurement. Two Leafs both showing 11 bars can have noticeably different real-world health, and that difference is money and range. The Aviloo test replaces the bars with an exact percentage, which is the number a buyer will actually accept. More in the Leaf battery guide.

Yes. Garages and dealers around South Wales get stock certified before sale, because certified EVs sell faster and hold their price. I come to the forecourt, each car takes around twenty minutes, and there’s volume pricing if you’re testing regularly. See the trade & dealers page, or WhatsApp me your rough numbers and I’ll send over the trade tariff.

Because the petrol engine barely runs, so neither does the thing that charges the 12V. Most PHEV miles happen on the electric motor. The little battery never gets a proper charge cycle, sags a bit further with every short trip, and dies years early. It’s not a fault, it’s just how PHEVs live. Which is why the £89 PHEV check includes a proper 12V load test.

Some drop is normal. PHEV packs are small and worked hard, so wear shows sooner than in a full EV. But losing a quarter or more of your range is at the high end even on an older car. The test measures it precisely, so you know whether you're inside normal tolerance or heading for a warranty conversation.

Not with the Aviloo certificate. Self-charging hybrids use a different battery setup that Aviloo doesn't cover. I can still do a full diagnostic and a 12V test on any hybrid. Not sure which kind you've got? WhatsApp me the reg and I'll tell you before you book anything.

A proper load test, not just a voltage reading: resting voltage, cold cranking amps under load, internal resistance and state of charge, with a straight Pass, Monitor or Replace verdict. If it does need replacing, the report gives you the exact spec to buy (AGM or EFB, CCA rating, case size) so nobody sells you the wrong one. From £25, any vehicle (a small mileage charge applies beyond 10 miles of Pontypridd). Details on the 12V check page.

The exact fault code, what’s behind it in plain English, and whether it’s urgent, expensive or nothing much. I scan every module, not the one or two a cheap code reader sees. From £35 at your address, written report the same day. The report is yours. Take it to any garage for the repair. See car diagnostics.

Yes. Clearing a warning light tidies the dashboard, not the car's memory. My scan reads codes that were stored and then cleared, across every module, with the history intact. 'I reset the dash' hides nothing from a pre-purchase check.

Different risks. The HPI check (£6 through PAD) searches the databases: outstanding finance, write-off markers, theft records, mileage discrepancies. The paperwork, basically. An inspection reads the car itself: fault codes, cleared history, battery health. Before real money changes hands you want both, and together they’re cheap next to a bad purchase. Free DVLA checks on the reg check page.

No, and it's on purpose. I diagnose; I don't repair. That means the report never has a repair bill riding on it. If something does need fixing, I'll point you at trusted local garages in Pontypridd and RCT, and the report gives them a head start on the job.
