Starting a gas and heating business can be a profitable venture with high demand, especially during colder months. Whether you want to offer boiler installations, gas safety inspections, heating repairs, or full central heating installations, this industry offers excellent earning potential.

This guide will walk you through the key steps to starting a successful gas and heating business from scratch.

✅ Step 1: Gain the Required Qualifications and Certifications

Before starting a gas and heating business, you must be properly trained and qualified.

💡 Continuous training is important—stay updated with new heating technologies (smart thermostats, renewable heating systems).

✅ Step 2: Register Your Business Legally

Choose your business structure and register it properly.
