Harlow-specific pitfalls

What to ask any installer
- Are you Gas Safe registered? (Ask for the number)
- Is the boiler being registered for warranty in MY name?
- Is a magnetic filter included?
- What's the written guarantee on workmanship?
- Who's actually doing the install — you, or a subcontractor?
