The short answer? It depends on how much the universe hates you that week. Generally, you’re looking at a range between £200 and £1,200 for a simple leak repair. But if the pipe has shattered under your driveway or the water board has to get involved, that number can easily hit £3,000 or more. I’m not joking.
Let’s break it down, because I know you’re already mentally checking your savings account. The first cost is the detection. You can’t just dig randomly—that’s a archaeologist’s job, not a plumber’s. Pros use listening sticks or thermal cameras to pinpoint the leak. This tracing service alone will set you back about £75 to £200. Annoying, but cheaper than digging up your entire lawn.
The real killer: access and labour.
If the leak is under a concrete path or your driveway, prepare for a labour bill that stings. Excavation by hand costs around £200–£400 per day. If they need a mini-digger? Add another £150–£300 for the hire. And remember, the plumber is charging you for the digging, the repair, and the time they spend swearing at the clay soil. That’s the hidden cost, right there.
Then comes the actual pipe repair. A simple pipe clamp might cost £50 for the part, but it’s usually a temporary fix. A proper replacement of a pipe section (including couplings and new pipe) runs between £150 and £600. And don’t forget making good—filling the hole, laying new turf, or repaving that driveway chunk. That’s another £100–£400. The irony? Your garden will look like a war zone for a month.
Let’s talk about the postcode lottery. A plumber in Cornwall might charge you £80 an hour, while one in London will laugh and say “£150, mate.” Rural areas can be cheaper, but you might wait two weeks for them to show up. Urban areas are faster but expensive. Pick your poison.
