ABT ACCREDITED · LIFETIME ACCESS · SELF-PACED
For anyone serious about gel as a career skill.
SLX Gel Builder is the beginner-to-professional foundation in one technique. You don't need previous experience or existing qualifications. What you need is the intention to do this properly.
By the end, you'll be ABT-accredited in builder gel. You'll understand the structure, the finish, the client experience, and the business alongside it.
Nothing about being new is a disadvantage here. Every professional nail artist started at zero. The question is where you go from there.
- You're starting your career in nails and want a real qualification, not just a certificate
- You've been doing nails for friends and family and want to turn it into a business
- You've completed shorter courses but feel gaps in your foundation
- You want to specialise in gel and build a signature finish clients recognise

Sarah, founder of SLX.
Sarah built SLX from her bedroom before moving to her Brighton studio, teaching herself the craft alongside a business management degree. That combination shows up in everything she teaches: the technique matters, but so does the business you build around it.
She teaches nail artistry as a craft with a career attached to it. Which is why SLX Gel Builder covers both the technique and the business fundamentals that turn a good set of nails into a career you actually want.

Things worth knowing before you enrol.
Do I need any previous experience?+
No. SLX Gel Builder is beginner-friendly and starts from the foundations. Every module builds progressively, so whether you've never touched a nail before or you've been doing them at home for friends, you'll be able to follow along and build real skill.
Is this actually ABT accredited?+
Yes. SLX Gel Builder is fully ABT-accredited. On completion of the course and assessments, you'll receive an ABT-recognised certificate. This qualification is what unlocks professional insurance and lets you work legally as a nail technician in the UK.
How long will the course take?+
Most of our courses can be completed in a couple of days but you can go at whatever pace you are comfortable.
What equipment do I need?+
You'll need your own builder gel supplies and a good-quality lamp to practise alongside the course. A full equipment list is provided in the first module, including specific product recommendations and where to buy them. If you're starting from zero, expect to invest around £150 to £250 in a starter kit. This is separate from the course fee.
Can I pay in instalments?+
Yes. You can pay £397 upfront, or split it across three monthly payments of £132. Both options are available at checkout.
Is the course all video?+
The teaching is video-led, module by module, with downloadable worksheets and reference sheets alongside it. You can watch on any device, pause mid-technique, and re-watch a step as many times as you need while you practise.
What if I decide the course isn't for me?+
You have 14 days from enrolment to request a refund, provided you've accessed no more than 25% of the course content. This gives you time to explore the material and make sure it's the right fit. Beyond that point, refunds are at our discretion, so we ask you to consider carefully before enrolling.
Do I get a certificate?+
Yes. On completion of the course and assessments, you'll receive your ABT-accredited certificate digitally by default, sent straight to your email in a printable, high-resolution format. If you'd prefer a physical certificate posted to you, just let us know during or after your enrolment. We're happy to send one at no extra cost.
How does SLX Collective's free trial work?+
Every enrolment includes 3 months of the SLX Collective community at no additional cost. You'll receive an invitation within a few minutes of your purchase. After the 3 months, you can choose to continue as a paying member or let the trial lapse. There's no automatic charge and no obligation.
What if I'm outside the UK?+
SLX Gel Builder is available worldwide. The course is delivered online in English, and the video lessons work on any device with an internet connection. ABT is a UK accreditation, so if you plan to work as a nail technician in another country, check whether your local licensing body recognises ABT or requires separate certification. We're happy to help clarify. Just get in touch.
