End‑of‑Summer Boiler Service: Why September Is the Smart Month to Book

Why September Is Smart for Boiler Servicing

September is the ideal time to book your boiler service—nestled between the summer lull and the winter rush. Booking now typically means shorter wait times, greater engineer availability, and confidence that your heating is winter-ready throughout South London and North Surrey.

What You Can Check Yourself

• System pressure: Should be 1.0–1.5 bar when cold. Needing to top up frequently could mean there’s a fault

• Radiators: Bleed them as needed, but remember to re-check boiler pressure afterward.

• Thermostat: Change batteries if needed, and adjust schedules for earlier sunsets.

• Condensate pipe: If it’s external, check that it’s insulated before winter.

What We Do on a Professional Service

• Combustion and flue safety checks

• Cleaning burner, heat exchanger, and condensate trap if required

• Expansion vessel pressure check and topping up if necessary

• Inspection of safety devices and seals

• System water quality test and advice on inhibitors

• Full service record to help protect your boiler warranty

When to Call an Engineer
