What to do if…
water starts bubbling up in the garden or driveway and you suspect a buried pipe leak

Short answer

Treat it as both a leak and a ground-collapse risk: keep people and vehicles off the area, reduce water flow by turning off your internal stopcock if you can, then report it to your water company (and your landlord/agent if you rent).

Do not do these things

  • Don’t dig to “find the leak” (you could hit other services or trigger a collapse).
  • Don’t drive or park over the bubbling/wet area (soft ground can fail suddenly).
  • Don’t delay reporting while you try to work out who “owns” the pipe — the water company can triage whether it’s their network or a private supply pipe.
  • Don’t ignore nearby electrics (garage sockets, garden lighting) if water is heading that way.
  • Don’t assume it’s “just rainwater” if it’s persistent, bubbling, or spreading.

What to do now

  1. Make a safe zone immediately. Keep people, pets, and vehicles away from the bubbling/wet patch. If it’s in a driveway, block it off and avoid using that section.
  2. Do a quick “is it still feeding?” check (without digging).
    • If you have a water meter, turn off all water inside and see if the meter still moves (or the flow indicator keeps turning).
    • If you don’t have a meter, watch whether the bubbling continues steadily even when you’re not using water indoors.
  3. Reduce the flow to limit damage. Turn off your internal stopcock/stop tap (commonly under the kitchen sink or where the supply enters the property).
    • If water is heading towards electrics you can’t safely isolate, increase distance and move to step 6.
  4. Report it to the right place (when unsure, report rather than wait).
    • If the bubbling/water is near the road, pavement, or outside your boundary (or affecting neighbours): report it to your water company as a leak straight away.
    • If it appears to be on your property (often the private “supply pipe” area): you’ll typically need a qualified plumber/leak repair, but still tell the water company if you’re unsure, if it’s close to the boundary/meter area, or if the flow is significant.
    • If you rent: inform your landlord/letting agent immediately (ideally in writing), and also report to the water company if it looks like it could be a street-side/boundary leak.
  5. Record what you can safely. Take photos/video showing:
    • the bubbling point (wide shot + close-up),
    • where it sits relative to the house/boundary/road,
    • any cracks, sinking, or water reaching structures.
  6. Escalate if there’s immediate danger. Call 999 if the ground is giving way, there’s a serious hazard to the public (e.g., roadway/footway collapse risk), or water is creating an electrical danger you can’t safely control.

What can wait

  • You do not need to decide today who will pay for repairs before you report it.
  • You do not need to dig test holes or “prove” where the leak is.
  • You do not need to arrange permanent repairs until the situation is stable and you know whether it’s likely the water company’s network (main/communication pipe) or your private supply pipe.

Important reassurance

Bubbling water from the ground is genuinely alarming. You don’t need to diagnose it under pressure — your priority is to keep the area clear, reduce water flow if you can, and get the water company/landlord involved quickly.

Scope note

This is first-steps guidance for the first hours. Once the leak is stopped or contained, next steps may include confirming pipe responsibility, repair planning, and insurer/landlord follow-up.

Important note

This is general information, not professional plumbing, legal, or safety advice. If you’re unsure whether it’s safe to approach valves or electrics, prioritise distance and contacting your water company or emergency services.
