What It Actually Costs to Put Your Name on a Bottle: Inside Britain's E-Liquid Start-Up Boom

There's a moment every e-liquid founder describes the same way. You're standing at the kitchen table, dropper bottle in hand, thinking you've cracked it. Six months later you're staring at an invoice for lab testing and wondering why nobody warned you.

We spoke to three founders — two still trading, one who folded quietly last year — about what it genuinely costs to get a British vape brand from idea to shop counter. The numbers might surprise you.

The Fee Nobody Mentions at Parties

Before a single bottle ships legally in the UK, your liquid has to be notified to the Medicines and Healthcare products Regulatory Agency (MHRA). It's not optional. Every single flavour, in every single nicotine strength, needs its own notification.

"People assume it's a one-off," says Priya, who launched a dessert-focused range in Birmingham in 2021. "But if you've got six flavours across three strengths, that's eighteen submissions before you've sold anything. And if you tweak a recipe? Back to square one."

On top of the regulatory fee sits the emissions and toxicology testing. A proper lab analysis from a UK-accredited facility runs into the hundreds of pounds per flavour. Cheap testing exists, founders told us, but reputable wholesalers ask for paperwork, and "my mate did it in his garage" doesn't cut it.

Compliant Bottles Cost More Than You Think

Then there's the packaging. TPD-compliant bottles — 10ml, child-resistant, tactile warning labels, the lot — cost more than the pretty 60ml unicorn bottles you see from American brands. Add in batch codes, nicotine warning artwork and a UK address printed on every label, and your unit cost creeps up before you've printed a business card.

One founder put it bluntly: "The liquid is the cheap bit. PG, VG and flavouring for a 10ml bottle costs pennies. Everything wrapped around it is where the money goes."

The Shelf Space Battle

Getting stocked is its own war. Independent vape shops — the lifeblood of the industry — get pitched by new brands constantly. Margins matter, yes, but so does story.

Which brings us to the interesting bit. Nearly every founder we spoke to mentioned the same trend: dual-identity branding. Ranges built around two clear personalities — a smooth custard twin and a sharp fruit sibling, say — are easier for shops to merchandise and easier for customers to remember.

"A shop owner has four seconds to explain your brand to a customer," Priya says. "Two flavours, two moods, one bottle? That pitch writes itself."

It's the logic behind brands like Gemini Vapour, and it's spreading. Simplicity, it turns out, sells.

The Realistic Budget

So what's the damage? Based on our conversations, a lean, compliant launch looks something like:

• Testing and MHRA notifications: £3,000–£8,000 for a small range
• Initial production run: £2,000–£5,000
• Compliant packaging and labels: £1,500+
• Insurance, company setup, branding: £1,000–£2,500

Call it £8,000–£15,000 before you've paid yourself a penny. The founder who folded? He launched on £4,000, skipped full testing, and couldn't get wholesale accounts. Draw your own conclusions.

Worth It?

Every founder said the same thing at the end: the ones who survive treat this as a regulated consumer goods business, not a hobby with stickers. Do the testing. Budget properly. And for heaven's sake, give your brand one clear idea a shopkeeper can repeat in a sentence.

The kitchen table is where it starts. The counter is where it's won.
