[Severn Trent says](https://www.stwater.co.uk/my-supply/tap-water/my-water-pipes/water-pipe-responsibility/) the pipe from the boundary stop tap to your house belongs to the homeowner, even where it crosses someone else’s land. Water supply pipe repair starts with knowing exactly where the leak is, because every extra hole in a drive or garden costs time and money to put back. ## One hole, in the right place If the leak has already been pinpointed and marked, the repair starts there. If not, it is located first with [underground water leak detection](https://nottsleakdetection.co.uk/underground-water-leak-detection/). A supply pipe normally sits between 750mm and 1,350mm below the surface, the depth the [Water Supply (Water Fittings) Regulations 1999](https://www.legislation.gov.uk/uksi/1999/1148) set to keep it clear of frost and damage. The hole is dug to that depth over the marked spot and made just wide enough to work in safely. ## Matching the repair to the pipe What the pipe is made of decides how it is repaired. Blue MDPE plastic, the material of most newer and replaced supplies, takes a compression repair coupling or a short new section. Lead pipe can be joined to new plastic with a purpose-made fitting, but a leak on lead is usually a sign of age. Older galvanised iron tends to corrode along its length, so a repair in one place is often followed by a leak somewhere else. Every fitting used is WRAS-approved, which means it has been tested against the Water Fittings Regulations. After the repair the pipe is pressure-tested with the hole still open, so any problem shows up before the ground goes back. ## When a repair isn’t the right answer A repair makes sense for a single leak on a sound pipe. It makes less sense when: - the pipe is lead, because Severn Trent‘s [Lead Replacement Scheme](https://www.stwater.co.uk/my-supply/tap-water/my-water-pipes/lead-replacement-scheme/) can give you a free new connection once your side is replaced; - it has leaked before, or the pipe is badly corroded; - the pipe runs a long way under a drive that would need lifting in several places. In those cases the report sets out the cost of a repair against a [water supply pipe replacement](https://nottsleakdetection.co.uk/water-supply-pipe-replacement/), often by [moling](https://nottsleakdetection.co.uk/water-pipe-moling/), so you can decide on the numbers. ## After the repair: getting the water back Once the leak is fixed, Severn Trent offers a one-off leakage allowance once the leak is repaired, covering up to 12 months or two bills based on actual meter readings. Keep the invoice and the photos from the repair, because the claim needs proof the leak was fixed. [How the Severn Trent leak allowance works](https://nottsleakdetection.co.uk/guide/severn-trent-leak-allowance/) covers the claim, and a letter giving you a deadline to repair is explained under [private leakage notices](https://nottsleakdetection.co.uk/private-leakage-notice/). ## What's included - Leak position confirmed on the ground before digging - One excavation over the leak, sized to the pipe depth - Damaged section cut out - Repair coupling or new section to suit the pipe material - Pressure test after the repair - Pipe bedded and backfilled in layers - Surface reinstated: turf, paving or temporary cover - Invoice and photos for your leakage allowance claim ## How the options compare Water Supply Pipe Repair: options compared Compare Do it yourself Dig-and-hope operator Proper leak detection Where the hole goes Wherever looks wet Trial holes along the run Over the marked leak Fittings used Whatever the shop had Often not matched to the pipe WRAS-approved, matched to the material Checked afterwards By waiting for the next bill Not always Pressure test before backfilling If the pipe is past repair Not spotted Patched anyway Told plainly, with replacement options ## Related resources - [Learn Who is responsible for the water supply pipe?](https://nottsleakdetection.co.uk/guide/who-is-responsible-for-water-supply-pipe/) - [Decision Guide How much does water supply pipe replacement cost?](https://nottsleakdetection.co.uk/guide/water-supply-pipe-replacement-cost/) - [Learn How does the Severn Trent leak allowance work?](https://nottsleakdetection.co.uk/guide/severn-trent-leak-allowance/) Water coming up now? 1. 1Turn off your internal stop tap.

It depends on the depth, the surface and what the pipe is made of, so it is priced once the leak is located. For comparison, Nottingham quotes for replacing a whole supply pipe run £388–£598. See [what supply pipe replacement costs](https://nottsleakdetection.co.uk/guide/water-supply-pipe-replacement-cost/). ### Can every leak be repaired, or will I need a new pipe? Most single leaks on a sound pipe can be repaired. If the pipe is lead, badly corroded iron, or has already leaked in several places, a repair only fixes today's leak, and [replacing the supply pipe](https://nottsleakdetection.co.uk/water-supply-pipe-replacement/) is usually better value. ### Who pays for a repair on a shared supply pipe? Everyone the shared section serves, jointly. A leak on the branch to your house alone is yours. See [shared supply pipe leaks](https://nottsleakdetection.co.uk/shared-supply-pipe-leak/). ### Do I need the water company's permission to repair my supply pipe? No. The supply pipe from the boundary to your house is yours to maintain. The repair has to meet the Water Supply (Water Fittings) Regulations 1999, which is why approved fittings are used. ### Are you open 24 hours? No. Lines are open Monday to Sunday, 9am to 7pm. Out of hours, turn off your internal stop tap to stop the flow and call us in the morning. If water is coming up in the road or on the pavement, that is on Severn Trent's side: report it free on 0800 783 4444 (+448007834444).
