FOUNDER'S NOTE — EST. BY PIOTR NAWIGOWSKI

FROM THE TRADE FLOOR TO YOUR DRIVER'S SEAT

A decade sourcing automotive parts taught me how much gets sold as a seat belt extender with no business near a vehicle's safety system. So I built the alternative: ECE R16 certified, ISO 9001:2015 manufactured, full stop.

01 — THE ORIGIN

WHY A PARTS-TRADE VETERAN STARTED A SEAT BELT EXTENDER COMPANY

My name is Piotr Nartowski, and I founded Seat Belts Extender UK after more than a decade working in the automotive aftermarket parts trade — sourcing, inspecting, and distributing components for garages and retailers across the UK.

That job taught me something most drivers never get to see: how much of what gets sold online as a seat belt extender has no business being anywhere near a vehicle's safety system. No ECE R16 testing. No traceable manufacturing standard. Just a metal buckle and a strap, listed for £8.99 with a stock photo and no paper trail behind it.

A seat belt extender isn't a phone case. It sits directly in the chain that's supposed to keep you or your child in place in a crash.

I wasn't comfortable seeing that treated like a throwaway impulse buy — and I didn't want to keep distributing parts I couldn't personally stand behind.

WHAT I SAW ON THE TRADE FLOOR

  • No ECE R16 test paperwork behind the listing
  • No traceable manufacturing standard
  • Sold as a generic universal fit, never checked
  • Priced and marketed like a disposable accessory

PIOTR'S BACKGROUND

02 — THE RULE THAT HASN'T CHANGED

ONE STANDARD, NO EXCEPTIONS

I set up Seat Belts Extender UK with one rule that hasn't changed since: every product we stock has to meet ECE R16 certification and come from an ISO 9001:2015-audited manufacturing process, full stop. No exceptions, no budget uncertified range sold on the side. If it doesn't pass, it doesn't go on the site.

What we won't sell

Uncertified imports with no test paperwork, sold as 'universal fit' with a stock photo and no traceable factory behind them — the exact listings Piotr spent a decade seeing move through the trade.

03 — IN PRACTICE

WHAT THAT STANDARD LOOKS LIKE, ORDER BY ORDER

02

We keep stock in the UK

Every order ships from UK stock with same-working-day dispatch — no waiting three weeks for an overseas supplier to fulfil a safety part.

We're upfront about the limits

If a product isn't right for your vehicle or your airline, we'll tell you before you buy it, not after.
Fit-first, not sale-first
04 — WHY I STILL DO THIS

THE MESSAGES THAT KEEP THIS BUSINESS HONEST

Every week I still get messages from customers who tell us they'd stopped wearing their seat belt properly — not because they didn't care, but because it dug in, sat wrong, or simply didn't reach.

That's not a comfort problem. That's a safety gap. Fixing it, properly and certifiably, is the whole reason this business exists.

IF IT DOESN'T PASS, IT DOESN'T GO ON THE SITE

That's the standard this business was built on, and it's the one I still apply to every product we list. If you've got a question about fitment, certification, or which extender is right for your vehicle or airline, get in touch. I read the support inbox myself.
