Frozen Condensate Pipe
Frozen Condensate Pipe
Frozen condensate pipe in South West London? It is the most common reason boilers shut down in a cold snap — and it is usually a same-visit fix.
About this service
Frozen Condensate Pipe in South West London, done properly the first time
Condensing boilers push acidic condensate out through a small plastic pipe. When that pipe runs outside, a hard frost freezes the water in it, the boiler detects the blockage and locks out — often showing an EA, E1 or F28-type code depending on brand.
Thawing it gets the heat back on, but if the pipe is undersized, badly routed or unlagged it will freeze again next cold night. The permanent fix is re-routing internally where possible, or upsizing and properly insulating the external run.
We attend frozen condensate call-outs across Kingston upon Thames, Richmond, Fulham and the rest of South West London through winter and, where you want it, put the permanent fix in at the same visit.

Frequently asked
Your questions, answered
Can I thaw a frozen condensate pipe myself?
Warm — never boiling — water poured along the exposed external pipe often clears it, then reset the boiler once. If it will not restart, or you cannot reach the pipe safely, call us.
How do I stop it freezing again?
Re-route it internally to a soil stack or waste where the layout allows, or upsize the external section and lag it with proper waterproof insulation.
Which fault code means frozen condensate?
It varies by brand — Worcester often shows EA, Vaillant F28, Ideal F1-type lockouts. The code is a starting point, not a diagnosis.
