If you've decided to grade your Pokémon cards, the next question is who should do it. There are more options than there used to be — including, for the first time, serious grading done start-to-finish in the UK. This guide covers exactly what to look for in a Pokémon card grading company, the questions worth asking before you post anything, and how to tell a genuine grader from a logo on a slab.
New to grading entirely? Start with our complete guide to Pokémon card grading in the UK — it explains what grading is, how the 1–10 scale works and which cards are worth it. This article assumes you've already decided to grade and focuses on picking the right company.
Why grade with a UK company?
For years, getting a Pokémon card graded to a recognised standard meant shipping it across the Atlantic and waiting — sometimes months — to get it back. A UK grading company removes most of the friction:
- No transatlantic risk. Your card never leaves the country. No customs, no import charges on the return, no parcel sitting in a depot overseas for weeks.
- Faster, cheaper postage. Domestic tracked, insured postage costs a fraction of international shipping, and the round trip is days rather than weeks.
- Real support. Same time zone, same consumer protections, and a company you can actually reach if something goes wrong.
We go deeper on the trade-offs in UK vs US card grading, but for most UK collectors the maths now favours grading at home.
What to look for in a Pokémon grading company
Not all grading is equal. A slab and a number on it are easy to produce; a grade you can actually trust is not. Here's what separates a serious Pokémon card grading company from the rest.
1. Consistency you can trust
The whole point of a grade is that it means the same thing every time. The risk with traditional grading is that it leans on human eyes — and humans are inconsistent, especially across busy days and different graders. Ask how a company actually arrives at a grade. Is it one person's opinion, an AI's guess at what a card "looks like", or a repeatable physical measurement? We explain why that distinction matters in AI grading vs measurement.
2. Turnaround that's actually stated
A good company tells you a clear turnaround and measures it from the day your cards arrive — not a vague "weeks to months". Be wary of services that won't commit to a timeframe. See how long card grading takes for what's realistic.
3. Transparent, flat pricing
Pricing should be simple to understand before you commit. Watch for value-based tiers (where you pay more to grade a more valuable card for the same work), express premiums, and surprise fees at checkout. A flat per-card price is the honest model. Our guide to grading costs in the UK breaks down what you should expect to pay.
4. Real authentication
Pokémon is one of the most counterfeited card categories in the world, and fakes have got good. A grading company worth using authenticates every card — not just eyeballs it — and will fail anything it can't verify. If a service grades condition but says nothing about authenticity, that's a gap. Learn how fakes are spotted and what a real authentication pass involves.
5. A slab and report worth having
The slab protects the card; the report explains the grade. The best companies give you a tamper-evident case and a detailed report showing how the grade was reached — centring, corners, edges and surface — rather than just a bare number. That report is what a future buyer trusts.
6. Insurance, tracking and safe returns
You're posting something valuable to a stranger. A credible company insures your cards while they're in its care, returns them on a tracked and insured service, and is clear about who carries the risk at each step. Don't send a grail to anyone who can't tell you exactly how it's covered.
7. Verifiable certificates and a public registry
Every grade should be independently verifiable. Look for a unique certificate number you (or a buyer) can check online, and ideally a public registry of graded cards. If a grade can't be verified, it's just a sticker. Here's how certificate verification works.
Red flags to watch for
- No clear method. If a company won't explain how it grades, assume the answer is "inconsistently".
- Grades but doesn't authenticate. A condition grade on a fake card is worthless — or worse.
- Vague timeframes and no fixed price. Both are signs of a process that isn't under control.
- No verifiable certificate. A slab nobody can check protects nobody.
- Unclear on insurance and returns. If they can't tell you how your cards are covered, don't post them.
How CALIBRE does it
CALIBRE is a UK Pokémon card grading company built specifically to close those gaps. The core idea is in our name and our motto — measured, not guessed:
- Physics, not opinion. Every card is physically measured — centring, corners, edges and surface — so the same card gets the same grade every time, not a different number on a different day.
- Authentication on every card. We verify each card before we grade it, using transmitted light, weight, UV and other passes. Anything we can't authenticate doesn't get a grade.
- Graded in the UK, fast. Our lab is in the UK and we target a 72-hour turnaround from arrival — no transatlantic round trip.
- Flat, honest pricing. One per-card price. No value-based upcharges, no holo premiums, no surprises at checkout.
- Tracked, insured, verifiable. Your cards come back on a tracked and insured service, sealed in a tamper-evident slab, each with a unique certificate and a full report you can look up in our public registry.
If that's the kind of grading you're after, you can start an order in a couple of minutes.
What it costs and how long it takes
UK grading is typically far cheaper than the all-in cost of shipping abroad once you count international postage, insurance and potential import charges. For the full picture, see our breakdowns of what grading costs in the UK and how long grading takes. CALIBRE charges a flat per-card rate and targets a 72-hour turnaround from the day your cards reach us.
Sending your cards safely
How you pack your cards matters as much as who grades them. Sleeve each card, use a top-loader or semi-rigid holder, and post on a tracked, insured service. Our step-by-step guide on how to package and send your cards walks through it so nothing gets damaged in transit.

Frequently asked questions
Which companies grade Pokémon cards in the UK?
UK collectors can now grade domestically rather than shipping to the US. CALIBRE is a UK-based Pokémon grading company that measures every card physically, authenticates it, and returns it sealed with a verifiable certificate — all without your card leaving the country. When comparing companies, focus on method, authentication, turnaround, pricing and whether grades are independently verifiable.
Is it better to grade Pokémon cards in the UK or send them to PSA in the US?
For most UK collectors, grading in the UK is faster and cheaper once you account for international postage, insurance and possible import charges — and your card never leaves the country. US grading can make sense for specific resale markets, but the convenience and cost gap has narrowed sharply. See our UK vs US grading comparison for the full trade-offs.
How much does it cost to grade a Pokémon card in the UK?
UK grading is generally much cheaper than the all-in cost of grading abroad. A good company charges a clear, flat per-card price with no value-based upcharges. Our UK grading cost guide explains what to expect.
How long does Pokémon grading take?
It varies by company. A serious grader states a clear turnaround measured from when your cards arrive. CALIBRE targets 72 hours from arrival. More on realistic timeframes in how long grading takes.
Are graded Pokémon cards worth more than raw cards?
Usually, yes — a verified grade removes a buyer's biggest worry (condition and authenticity), and high-grade cards typically sell for more than raw equivalents. The premium depends on the card and the grade. See is grading worth it and raw vs graded cards.
How do I know a Pokémon grading company is legitimate?
Check that it explains its grading method, authenticates every card, states a clear turnaround and price, insures your cards in transit and in its care, and issues a unique certificate you can verify online — ideally backed by a public registry. If any of those are missing, be cautious.
