Many homeowners in London skip their annual boiler service thinking it’s an unnecessary expense. But what most don’t realise is that neglecting your boiler can cost far more in the long run — in energy bills, emergency repairs, safety risks, and even boiler replacement.
💷 What Does a Boiler Service Actually Cost?
A standard boiler service in London typically costs £85–£120 depending on your location, boiler type and provider.
✅ It includes safety inspections, cleaning, efficiency checks, and a full service report — usually completed in under an hour.
Compared to repair bills and inefficiency losses, it’s a small price to pay.
🛠️ The Hidden Costs of Skipping Boiler Maintenance
Neglecting a simple annual check can lead to:
- 💸 Higher gas bills – Dirty or faulty boilers run less efficiently
- ❌ Voided warranties – Most manufacturers require annual service
- ⚠️ Breakdowns – Unchecked parts can fail unexpectedly
- 🔥 Carbon monoxide risk – Undiagnosed faults may lead to dangerous emissions
- 🔄 Premature replacement – A poorly maintained boiler has a shorter lifespan
A £100 annual check can prevent a £2,000+ replacement or emergency callout.
