Overview

Glaziers install, repair, and replace glass in windows, doors, shopfronts, conservatories, and curtain walling. With the UK's focus on energy efficiency (double and triple glazing upgrades), new-build housing, and commercial construction, glaziers are in strong demand. The trade combines practical skills with technical knowledge of glass types, thermal performance, and building regulations. It's a rewarding career with good progression into management or business ownership.

Step-by-Step Career Path

Get Started

GCSEs in Maths and English are helpful. Technical drawing or Design & Technology are a bonus. No formal qualifications are strictly required to start.

Start an Apprenticeship

A Level 2 Apprenticeship in Glazing takes 2-3 years. You'll learn glass cutting, window installation, sealed unit replacement, and safety procedures. The Glass Qualifications Authority (GQA) sets the standards.

Complete NVQ Level 2 in Glazing

Covers fenestration installation (windows and doors), glass processing, sealed unit manufacture, and compliance with building regulations. You'll work with various glass types and frame materials.

Get Your CSCS Card

Required for construction site work. Your NVQ and CITB Health & Safety test qualify you for the Blue Skilled Worker card.

Add FENSA or CERTASS Registration

If installing replacement windows and doors, your employer needs FENSA or CERTASS registration to self-certify compliance with building regulations. Understanding these schemes is essential.

Specialise and Progress

Specialise in commercial glazing (curtain walling, structural glass), heritage glazing (leaded lights, stained glass), or start your own window installation business.
