Step 2 - The Heating Adviser visit

- You'll get a fixed price quote - so even if there's unexpected work, you won't pay a penny more.
- If you wish to go ahead, they’ll arrange a date for your installation.
Step 3 - Your new boiler installation

- Before they start, our Engineer will take you through a safety briefing to ensure you and anyone else in your property remain safe at all times.
- They will cover carpets and protect surfaces to minimise damage to your property.
- Once finished, they’ll explain how to use your new boiler and what to do if you need any help after.
Step 4 - Our guarantee to you
