Here’s a little twist. If the leak is on your side of the water meter (i.e., after it enters your property boundary), you’re footing the bill. It’s your pipe, your problem. But if the leak is on the public side—before the meter or under the pavement—the water company has to fix it for free. Most people don’t know this. So check your meter location before you panic. You might get lucky.

But wait—there’s a catch. Some water firms offer a leak allowance. If you have a sudden, documented leak, they might refund part of your elevated water bill. You’ll need proof of the repair (invoice, photos). It’s not automatic, so you have to ask. Think of it as begging for mercy from a corporation.
Can you DIY it?
I admire your optimism, but don’t. Digging up a pipe sounds like a weekend project until you hit a gas line or a fibre optic cable. A friend of mine tried it, and he ended up flooding his neighbour’s basement. The repair cost him £4,000, plus a bottle of whiskey for the neighbour. Just hire a professional. Seriously. Your back and your marriage will thank you.
If you’re insured, check your home policy. Some cover accidental damage to underground pipes. Others see it as “wear and tear” and laugh at your claim. Read the small print. Usually, you’re not covered, but if you have “home emergency cover” (like from British Gas or a standalone policy), it might pay for the trace and repair. That’s worth a phone call while you’re sitting in the garden staring at the hole.
