What is stl-training.co.uk and what training does it provide?

Updated

STL Training is a London-based learning and development provider offering instructor-led courses in two broad areas: workplace software skills (Excel, Power BI, Microsoft Office, Copilot and ChatGPT) and people skills (soft skills, management, leadership, sales and customer service). Courses run as public scheduled sessions in face-to-face or online classrooms, and as on-site training for organisations. It is a fit if you want short, skills-focused courses with published dates you can book individually; it is less suited if you need accredited qualifications or a fully customised long programme, since the site presents standard course titles rather than bespoke curricula.

Course areas

The site organises its catalogue into distinct streams:

Area Example courses listed
Excel Introduction, Intermediate, Advanced; Advanced Formulas & Functions; Advanced for Power Users; Charting; Forecasting & Data Analysis; VBA (Intro/Intermediate/Advanced); PivotTables; PowerPivot; Financial Modelling; Excel for Finance Professionals
MS Office Power BI, MS Copilot, PowerPoint, Access, Word, MS Project, Microsoft 365, SharePoint, Outlook, Visio, Teams
Copilot, ChatGPT and AI Introduction to Microsoft 365 Copilot, Copilot for Advanced Users, Microsoft Copilot Explained, Microsoft Copilot Engage, Microsoft Copilot Champions, ChatGPT for Busy Decision Makers, ChatGPT for Professionals
Professional development Taking Minutes, Time Management, Organisational Skills, Negotiating Skills, Presentation Skills, Effective Communication, Building Confidence & Assertiveness
Management Introduction to Management, Managing Teams Remotely, Mentoring, Managing Change, Leadership Development, Motivating Skills, Stress Management
Sales & customer service Customer Service Excellence, Account Management

The site states it offers "70+ courses" in the professional development area and "50+ courses" in management, so the catalogue is broad rather than deep in any single niche.

Delivery formats

  • Public scheduled courses — instructor-led, available face-to-face or in online classrooms, with dates you can view and book. The site says public courses are "never cancelled."
  • On-site training — delivered at the client's location, described as "proven reliability."
  • Reach — London-based, with delivery described as UK-wide and in 85+ countries.

Scale and quality signals

The site publishes several performance claims: 99.26% of training objectives met, 98.3% customer recommendation, "transparent quality control," and 109,332 searchable testimonials. These are the provider's own figures, so treat them as marketing claims to verify — for example, by reading testimonials for a course close to your needs or asking for references before booking on-site training. One quoted review comes from a Learning & Development Manager at the Home Office, which suggests some public-sector client experience.

How to decide

  • Choose STL if you want a bookable public course in Excel, Power BI, Office tools, AI/Copilot, or management and soft skills, delivered in London or online, and you value a wide menu of short courses.
  • Look elsewhere or ask first if you need accredited certification, a multi-month development programme, or heavy customisation — the site's presentation centres on named standard courses.
  • Next step: check the schedule for your course and format, confirm the level (e.g. Excel Advanced vs. Advanced for Power Users) matches your current skill, and for organisational bookings request a callback via the number listed on the site to discuss on-site delivery.
