Why September Is the Best Time to Book Your Boiler Service
Book before the October rush and you get a calmer appointment, faster diagnosis of any faults, and a boiler that's actually ready for winter.
Every year plays out the same way: the first genuinely cold week arrives, thousands of households turn the heating on for the first time in months, and engineers' diaries fill up fast. Booking in September avoids all of it.
You beat the bottleneck
Between mid-October and Christmas, appointments across SW London get booked out one to two weeks ahead, and emergency call-outs jump the queue ahead of routine servicing. In September, we can usually offer a slot within days.
Faults get found before you need the heating
A boiler that's sat idle over summer is where problems hide — seized pumps, sticking valves, blocked condensate traps. Finding these in September means a planned repair on a mild day, not a cold house in December while parts are ordered.
It protects your warranty
Manufacturers require documented annual servicing to keep the warranty valid. A September service keeps that paperwork current for the whole winter ahead.
