If you’ve opened a letter saying there’s a leak on your private water supply pipe — and you’re staring out the window thinking “but there’s no leak”… you’re not the first. I’m Stuart, a local sole trader based in Orpington, and I deal with these Section 75 notices around BR5/BR6/BR7 and Bromley every week.
If you’ve got a deadline (or you’re selling a house) and you need quick clarity, call. If I can’t get to you immediately, I’ll still talk you through making it safe and checking the meter so you’re not guessing.
Most “private supply pipe” notices are triggered because the meter shows constant usage. Sometimes it’s a real underground leak. Sometimes it’s a shared supply issue. Occasionally it’s a false signal. Either way, you want facts fast.
Quick meter sanity check: turn everything off (taps, washing machine, dishwasher). Then watch the meter. If it still creeps or spins, water is flowing somewhere.
If you’re stuck on who’s responsible (private vs shared vs boundary), work out if the leak is actually on your side of the boundary.
Sometimes abnormal usage is caused by a water leak under sink or a slow ceiling leak from bathroom above rather than a buried supply pipe.
If you’re trying to rule out “inside the house” causes first, start with those two guides before you assume it’s underground.

If this leak notice is messing with your heating: a private supply issue can show up as pressure problems, boiler lockouts, or a system that won’t behave properly. These guides match the most common “panic” symptoms:
And if you’re under pressure right now, just call me on 07706 889 614. If you’re near Orpington High Street or stuck around Bromley South and need immediate direction, I’ll talk you through isolating and testing it so the letter doesn’t control your day.
This isn’t a “nice to do when you have time” letter. It’s Thames Water using legal powers to make sure wasted water gets fixed. You don’t need to panic — but you do need a plan.
Most notices give 7–14 days to investigate and take steps. Waiting for “the full month” is how people end up with enforcement on top of the repair cost.
Orpington and Bromley have loads of older streets where pipes feed more than one home before they split. If you’re unsure what’s yours and what isn’t, start here: who’s responsible for the leak?
If you start digging blind you’ll waste time and money. Detection pinpoints the leak so the repair is targeted. That’s why non-destructive leak detection saves so much hassle.
In clay soil, patch repairs can be short-term. If the pipe is old lead/galvanised and already failing, replacement with modern MDPE is often the “never deal with this again” option.
Reality check: Thames Water doesn’t “find the leak for you” on your land — they act on meter behaviour and responsibility assumptions. Your quickest win is proving what’s actually happening (responsibility + location) so you’re not guessing.
If you’re also confused about shared infrastructure generally (especially older properties), this explains the principle clearly: shared drains and sewer responsibility.
People get stressed because they think they need a legal dissertation. In reality, you usually need clear evidence: what we found, what was repaired, and when it was made watertight.
If your situation is mainly confusion about boundary and responsibility, read this first: private supply pipe responsibility explained.
The short answer: London Clay + old housing stock.
Clay swells when wet, shrinks when dry, and it pushes pipes around season after season. Pair that with older lead supplies in Victorian/Edwardian pockets and galvanised steel in some 1930s homes and you’ve got a recipe for quiet leaks.
You’ll often see notices after heavy rain (water softens the ground), or after pressure fluctuations. If you’ve had street works nearby, that can be the final straw for a tired private line.
I’m regularly around Orpington High Street, the back streets off Crofton Road, and the Bromley loops near Bromley South / The Glades. The “no visible leak” calls are common in those areas because leaks sit under paving and don’t surface.
Underground leaks don’t always announce themselves. Sometimes the only sign is:
If you’re stuck at this stage, the next sensible move is detection: locate an underground leak without ripping up the whole place.
I’m Stuart — sole trader, based in Orpington. SKR Plumbing & Heating launched in 2020, but I’d already been on the tools with other firms before that.
I got pulled into “leak notice” work because local homeowners kept calling in a panic, and the advice they were getting was all over the place: some were told to “just dig until you find it” and others were paying twice because a patch repair didn’t last.
I’d rather tell you the truth on the phone — even if it means you don’t book — than turn up, make a mess, and leave you with a half-solution while Thames Water keeps chasing.
Not a generic plumbing checklist — this is how these jobs actually unfold around Orpington and Bromley.
Meter test + isolation checks. We make sure we’re not chasing a supply-side issue or a shared pipe dispute. If you’re unsure about responsibility, read: private vs shared vs boundary responsibility.
Using proper detection methods so the repair is targeted. Full detail here: our Orpington/Bromley leak detection service.
If it’s a one-off fault on decent pipework, a repair can be fine. If it’s old lead/galvanised and already failing, replacement can be the sensible “one and done” approach.
The aim is not just “water back on”. It’s being able to close the case and move on. For general repair work, see: our plumbing repairs page.

“We honestly thought Thames Water were wrong because we couldn’t see anything. Stuart explained the meter test, found the leak under the drive, and didn’t make a mess.”
“Shared pipe situation with a neighbour. We were going in circles until we got it properly checked. Once it was proven where it was, it stopped the arguing.”
“Fast response and very clear about costs. Didn’t try to upsell. Just told us what needed doing and got it sorted.”

Different questions, different moods — because that’s how it is when you’ve got a letter and a deadline.
Most letters give 7–14 days to investigate and take steps. Some enforcement cycles can run longer, but if you’re unsure, don’t gamble on “it’ll be fine”. Call me and I’ll help you interpret what your specific notice is asking for.
Totally normal. Underground supply leaks often don’t surface — especially under paving or driveways. A meter test is usually the quickest way to confirm if water is still flowing when everything’s off. If you want to rule out internal causes first, check: water leak under sink and ceiling leak from bathroom above.
Often, yes — the section from boundary/meter to your internal stop tap is usually classed as private. Shared supplies and unclear boundaries are where it gets tricky, which is why isolation checks matter. This page breaks it down clearly: private supply pipe responsibility (Orpington & Bromley).
It can slow it down if it’s ignored. The quickest way to protect the sale is to prove what’s happening (meter + detection), then fix it properly so the buyer can see it’s resolved.
