Compare TEFL Course Providers

The table below is the heart of this guide. It shows each provider’s flagship course, the price displayed on its website when we checked, its stated accreditation, its Google rating, and its refund policy, all in one place. The accreditation column carries a label summarising the strongest claim each provider makes on its own pages, so you can see at a glance which qualifications are government-regulated and which rest on an unnamed badge.

A reputable online TEFL certification costs between roughly £150 and £300 (or the equivalent in euros or dollars) at the time of checking, once sale prices were applied. Advertised “regular” prices are far higher, from £379 to €635 among the providers compared here, but near-permanent promotions mean almost nobody pays them. The more useful comparison is what you get for the sale price: course hours, qualification level, tutor access and job support.

Two things matter more than the headline number. First, the qualification level: a 120-hour certificate (equivalent to Level 3) is the entry standard, while a Level 5 diploma carries more weight with employers and covers more teaching hours. Second, the extras that are easy to overlook: extension fees after your access period ends, whether tutor feedback is included, and whether job support continues after graduation.

Every provider in this comparison claims accreditation, but the claims are not equivalent. The strongest form is a qualification regulated by a government body: Ofqual in the UK regulates Level 5 TEFL diplomas awarded through approved awarding organisations such as Highfield and Qualifi. DEAC approval (through its Approved Quality Curriculum programme) is a recognised American benchmark. Beyond that sit independent accreditors such as the British Accreditation Council and ACDL.

On the pages we checked, The TEFL Institute and TEFL Org named the broadest range of accrediting and regulating bodies. The TEFL Academy and i-to-i both cite Ofqual regulation and DEAC approval. ITTT and myTEFL describe their courses as accredited but list their accreditors far less specifically on their sales pages, making independent verification harder. If accreditation matters to your visa or employer, always ask a provider exactly which body regulates the qualification, not just the company.

You do not have to take any provider’s word for it, ours included. Every Ofqual-regulated qualification has a public entry on the Ofqual register of regulated qualifications, maintained by Ofqual itself. Our two diplomas are listed there as 610/1571/4 (Level 5 Diploma in TEFL, 180 GLH) and 610/1573/8 (Level 5 Advanced Diploma in TEFL, 300 GLH, 54 credits), both awarded by Highfield Qualifications, Ofqual organisation number RN5219. If you want the longer explanation of what those numbers mean, we wrote it up in what the Ofqual register actually tells you, and our own accreditations are set out on our accreditation page.

Tutor support is near-universal at this end of the market, so the real differentiators are live contact time and what happens after you qualify. Look for scheduled live workshops rather than email-only feedback, and for job support that continues throughout your teaching career rather than a one-off CV template.

A jobs board is the common denominator here; every provider in the table has one. The question worth asking is whether anyone tells you when the big programmes actually open, because most of them recruit once a year and close without a reminder. Our own answer to that is The Hire Wire, a free fortnightly briefing on who is hiring, what it pays and when applications close, with a salary index, visa desk and deadline alerts behind it. It is free and open to anyone, whether or not you study with us, so it is worth a look even if you choose a different provider from this table.

Independent review scores among these six providers ranged from 4.4 to 4.9 out of 5 at the time of checking. The TEFL Academy and The TEFL Institute tied for the highest score, both at 4.9, with The TEFL Academy ahead on volume (2,248 reviews against our 1,874). i-to-i had the largest review volume of any provider here (3,232 reviews) at the lowest confirmed score (4.4). You can read our reviews on Google. myTEFL’s Google page could not be verified when we checked, so we report no score rather than an unconfirmed one.

One note on dates, in the spirit of the rest of this page. Every competitor figure here was taken on 25 July 2026, while our own was rechecked on 26 August 2026, so ours is the fresher number. Google rounds large totals to “1.9K” in some views; the exact count on the listing’s review summary was 1,874, and that is the figure we use.

When you read TEFL reviews, weigh the score together with volume and recency, and look at how a company answers its critical reviews. A 4.7 with hundreds of detailed recent reviews can tell you more than a perfect score built on a handful.

Refund terms vary more than any other feature in this comparison. ITTT offers the most unconditional promise: a full refund within 3 days of payment, no questions asked, plus a price-match guarantee. We offer a 14-day money-back guarantee. The TEFL Academy relies on the standard 14-day statutory withdrawal right set out in its terms and conditions. i-to-i’s “guaranteed pass” promise refunds you only if you fail despite following all tutor feedback. TEFL Org did not prominently state a guarantee on the pages we checked, and myTEFL’s terms state that online course fees are not refundable once you have enrolled. Read the refund clause before you pay, not after.
