SUPPLIES BOUGHT SEPARATELY · AROUND £100 TO BUILD YOUR PROFESSIONAL KIT
For anyone serious about builder gel and gel polish as a career skill.
SLX Builder Gel & Gel Polish is the beginner-to-professional foundation across two techniques. 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 and gel polish. 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 builder gel & gel polish and build a signature finish clients recognise

Your questions answered
Do I need any previous experience?+
No. SLX Builder Gel & Gel Polish 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.
Do I need to buy supplies separately from the course price?+
Yes. The course covers technique; supplies are separate. We provide a product list on enrolment with exactly what to buy and where. Building your kit costs around £100. These are the same products Sarah uses in the SLX Studio, so you'll be training on the professional standard from day one, and you'll keep the kit to use on your own clients afterwards.
Is this actually ABT accredited?+
Yes. SLX Builder Gel & Gel Polish 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.
Are there any age restrictions?+
SLX Academy courses are open to students aged 16 and over. This is due to industry insurance requirements and the professional nature of the training.

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.
What if I'm outside the UK?+
SLX Builder Gel & Gel Polish 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.
