Online Car Parts UK Vehicle Parts

Our interest: we earn a commission if you buy through the link on this page. It costs you nothing. The company structure, the customs warning and the Scottish tyre exclusion below are reported as the site publishes them, including where they count against it.

Start with the single most useful thing we found. Onlinecarparts.co.uk and Buycarparts.co.uk are run from the same place by the same people. Same address at Gewerbering 38a, Röttenbach; same commercial register entry, HRB 21524 at the District Court of Fürth; same managing director, Andreas Beraz; and the same company named as the seller of the goods, AUTODOC SE of Berlin.

Neither site tells you about the other. If you are “shopping around” across the two, you are comparing one shop with itself, so put them side by side on the actual part number instead and let the lower price win.

None of which makes this a bad place to buy. The catalogue is deep, it finds parts from your registration number, prices include 20% VAT, and delivery is £8.45 or free over £130. The things worth knowing are the ones further down: a customs warning, tyres that will not go to Scotland, and bulky items that cannot come here at all.

Who the seller is, and the arbitration line worth reading

The imprint names three layers. The website owner is Partio GmbH & Co. KG, VAT number DE281524963. Its personally liable shareholder — the general partner — is Partex Global GmbH, which is the company that owns Buycarparts.co.uk. And the vendor of the goods is AUTODOC SE, VAT number DE260634589, registered at Berlin Charlottenburg under HRB 247677 B.

As with its sister site, no UK company is named: no Companies House number, no UK address, and no telephone number on the contact page — which says “contact us by telephone or e-mail” and then gives neither.

There is one line here that is not on the other site, and it is the kind of thing that only matters once: the imprint states that AUTODOC is “neither willing nor obligated to participate” in consumer arbitration board dispute resolution. That is a lawful position for a German trader to take, and it is honest of them to publish it. It also means that if a dispute goes beyond email there is no free arbitration route — which is the practical reason to put this on a credit card or PayPal rather than a debit card.

Small sign of how the site is maintained: the About page carries the heading “Über Pkwteile” twice — untranslated German, naming a different brand in the same group. The range claim does not hold still either, with the banner promising “more than 2,500,000 car parts” and the page text on the same homepage saying “over 1,000,000 items”.

Delivery, and three exclusions that are easy to miss

The postage structure matches the sister site almost exactly, which is the clearest evidence of the shared operation:

Those last two rows are the ones to read before you fill a basket. Bulky items cannot be sent to the UK at all — so exhausts, body panels and anything long or awkward are off the table. And “tyres are not shipped to Scotland”, stated flatly, with no explanation and no alternative offered.

Then there is the customs line, which deserves its own paragraph: “for orders exceeding £135 in value, customs duties may be payable by you”. On a .co.uk website quoting sterling prices inclusive of 20% VAT, that is a real sting. It means the free-delivery threshold of £130 and the customs threshold of £135 sit five pounds apart, and an order nudged over £135 to get free postage can arrive with a bill attached.

Practical advice: if your basket lands between £130 and £140, either split it into two orders or accept the £8.45 and stay under £135. Saving £8.45 of postage is not worth risking a customs charge and a courier handling fee.

Dispatch is “within 1-2 working days after the receipt of payment”, with no deliveries on public holidays. No carrier is named in text — only DHL and GLS logos appear — and we found no cut-off time, no next-day option and no Saturday option. Northern Ireland and the Highlands are not mentioned either way.

Four real prices, and a tip hidden in one of them

These are live listings we read on 8 October 2026, all inclusive of 20% VAT and exclusive of delivery:

Now the tip. That Bosch disc listing publishes something almost nobody else does: it states the part “fulfils ECE standard: ECE-R90” and gives the actual type-approval code, E4-90R-02C-0786/3289.

ECE Regulation 90 is the European type approval for replacement brake pads and discs, and that code is the proof rather than the claim — the E4 identifies the approving country, 90R the regulation, and the rest is the specific approval. Plenty of sellers write “R90 approved” in the description and publish no number at all.

Use that as your test. When you are buying brake pads or discs anywhere, look for a printed approval code on the listing or the box. If a seller claims approval but cannot show you the number, treat the claim as unverified.

One caution on the listings themselves: they instruct you to “observe technical data” and “observe dimensions”, and that is the whole of the guidance. There is no statement anywhere about who is responsible if the part does not fit, so the measuring is yours to do.

Finding the part, and paying

Fitment works from a registration number, or by stepping through maker, model and engine. There is no VIN search, which is the one thing that settles a mid-production specification change, so compare the dimensions on the listing against the component you are taking off. On that Bosch disc, for instance, the 295 × 28 mm and the 5 × 112 bolt pattern are the figures that matter, not the vehicle name.

Payment is where the site contradicts itself again, mildly. The homepage text says “we accept PayPal, Visa, Discover, American Express, and bank transfer”; the payment page lists bank card, PayPal and bank transfer; and the footer logos add Mastercard. Mastercard is almost certainly fine, but the three lists do not match. No Klarna, no Clearpay and no trade account that we could find.

Customer service hours are the same as the sister site — Monday to Friday 7am to 8pm, Saturday 7am to 4pm, closed Sunday — and again there is no phone number published to call during them.

On returns we have to be straight with you: the footer lists “Right of withdrawal”, “Returns & refunds” and “Core exchange”, but we could not open those pages to read the terms, so we are not going to tell you what they say. Given the shared imprint they are likely to mirror the sister site’s — a 14-day right to withdraw, return postage at your cost, and notice to AUTODOC SE in Berlin — but likely is not verified, and we do not publish likely as fact. Read those three pages yourself before you order anything you might send back.

How to use this site sensibly

Our view, plainly. This is a competent European parts catalogue with a British domain name, and it is a good place to buy routine service items you are ordering in advance. Spark plugs at £4.75 and a branded front disc at £39.72 are keen prices, and the fact that a disc listing carries its real R90 approval code is a mark of a serious catalogue rather than a drop-shipper.

Four rules make it work for you:

• Keep the order under £135, or well over it with the customs risk accepted, so you are not caught between the postage threshold and the duty threshold.
• Check the price against Buycarparts.co.uk on the exact part number. It is the same shop, and the two do not always price identically.
• Measure before you order. No VIN lookup, no fit guarantee, and the listings simply tell you to observe the dimensions.
• Pay by credit card or PayPal. There is no UK entity, no phone number, and the seller has published that it will not take part in consumer arbitration.

And do not plan a same-week repair around it. One to two working days to dispatch, no next-day option, no cut-off time published, no bulky items to the UK, and no tyres to Scotland. For a job on the ramp on Saturday, buy local.
