A town with no old plumbing in it
Cambourne is unlike anywhere else we work. Construction began in June 1998 on 400 hectares of former farmland, and the first house was occupied in August 1999. There is no Victorian terrace here, no inter-war semi, no back boiler behind a chimney breast. Everything under the floors was installed within the last twenty six years.
That changes what goes wrong and how we fix it.
Great Cambourne and Lower Cambourne were the original phase, built from 1998 and 1999 onwards under the first 3,300 home permission, with Bovis Homes, Bryant Homes and Taylor Wimpey named for that initial development. Houses on Jeavons Lane, Greenhaze Lane and Monkfield Lane are now at the age where the first generation of fittings has had enough.
Upper Cambourne started in 2008, with a further 950 homes permitted on 3 October 2011 and completion estimated around 2018. Those properties are only now reaching the point where boilers, shower valves and cylinder controls begin to fail.
Cambourne West got outline permission in January 2017 for roughly 2,350 homes in three neighbourhoods, Sheepfold at 429 homes, Swansley Park at 918 and Woodfield at 1,003, with access from Sheepfold Lane off the modified A1198 roundabout. Some of that is barely out of warranty.
In stock of this age the pipework is often plastic barrier pipe run in push fit from manifolds rather than soldered copper. That is not a criticism, it is just a different animal. It means we trace pipe differently, we repair it differently, and we do not go cutting into a floor on a hunch.
Where the stopcock is in a Cambourne house
The good news about a modern town is that you do not have to go hunting behind a hundred years of kitchen units. In most Cambourne houses the internal stopcock is in the utility area, under the kitchen sink or in a service cupboard, and it is usually accessible.
Outside there is a stop tap and a meter in a chamber near the boundary. Everything from the boundary into your home is your pipe and your repair bill, which is worth remembering on the larger plots where that private run is a long one.
If we are in the property for anything else, we will find the stopcock, check it actually turns, and show whoever else lives there how to use it. It is a ten minute job that turns a flood into a puddle.
Hard water at 317.8 mg/l, and what it does to a combi
Cambridge Water supplies the mains water here. The parish of Cambourne falls in Cambridge Water’s Coton water quality zone, Z6, and the company’s own published water quality report for that zone for 2025/26 gives a total hardness of 317.8 mg/l of calcium carbonate, which is 22.2 Clark degrees, with average calcium of 120.4 mg/l. That is Cambridge Water’s published figure for the zone, not a reading we have taken in your house. Cambridge Water itself says that all of the water it supplies is hard.
Anything above 300 mg/l is normally called very hard, and in a town where almost every home is heated by a modern boiler that matters more than usual. Combination boilers make hot water on demand through a plate heat exchanger, and a plate exchanger in water this hard scales up. The classic symptom is hot water that starts warm and then runs cold, or a boiler that fires perfectly for heating and then cuts out on hot water only.
That is why we talk about scale reduction on the incoming main and about keeping inhibitor dosing right, and it is worth checking your own boiler paperwork because many manufacturers set conditions about water treatment in hard water areas.
The same scale seizes isolation valves, blocks tap cartridges and kills the temperature control on a shower mixer. In houses that are twenty odd years old, the original shower valves and brassware are usually the first thing to go.
The everyday work we do around CB23
Leaks and burst pipes. Failed push fit joints, damaged plastic pipe, weeping manifold connections and frost splits.
Taps, valves and stopcocks. Drips, seized isolators, scaled up mixer cartridges and outside taps with proper backflow protection.
Toilets and cisterns. Running fill valves, failed flush mechanisms, loose pans and leaking pan connectors.
Radiators and TRVs. Cold radiators, stuck thermostatic heads, radiators removed and refitted for decorating, and balancing.
Appliance plumbing. Washing machines, dishwashers and fridge water feeds, with isolation you can get at.
Cylinders and mains pressure. Immersion heaters, thermostats, unvented cylinder servicing and discharge pipework, and poor flow at the taps.
Emergencies. No water, a leak that will not isolate, or water coming through a ceiling.
We do small jobs too. One tap, one valve, one loo, and we would rather come and do it than send you elsewhere.
Clay ground, SuDS and why water sits on the surface here
The ground at Cambourne is clay, and it does not drain like chalk. The nationally known Lamb Drove scheme, 35 affordable homes on a one hectare site built by Cambridge Housing Society with residents moving in during spring and early summer 2006, is a demonstration sustainable drainage project precisely because the ground is impervious. It relied on surface based treatment rather than soaking away into the soil, using water butts, permeable paving in the residential roads, a green sedum roof, swales, filter strips, detention basins and a retention pond.
That is the pattern across the town. Surface water here is managed by the landscape as much as by pipes, and the wider water management story includes the lakes and ponds inside Cambourne Nature Reserve, 90 hectares across several areas around the town.
Two practical points follow. If water is standing on your drive or patio after heavy rain, a soakaway is often not a viable answer on this ground. And if you suspect an underground leak, the water will not necessarily disappear the way it would on chalk, which changes how we go about finding it.
Sewerage is Anglian Water, and it is worth knowing that Anglian Water took over responsibility for the pumping stations here on 8 October 2016. If you have an issue on a shared pumped system, that is who owns it now.
The properties where the job gets more interesting
Twenty five year old Great Cambourne stock. First fittings, first bathrooms and second or third boilers. Everything that was installed at once is now failing at once, which is normal for a town built in a single go.
Apartment blocks and shared buildings. The practical issue is isolation. Knowing which valve serves which flat before starting means one repair does not leave several households without water.
Manifold plumbing. Where a house is fed from a central manifold in plastic pipe, an individual run can often be isolated without shutting the whole property down, which is a genuine advantage during a repair. It also means the pipe route is nothing like the route you would guess in an older house.
The newest Cambourne West plots. Barely lived in, and the faults tend to be installation issues rather than wear. If a property is still inside a developer warranty period, we will say so rather than charging you for something you should not be paying for.
Winter, and where Cambourne pipes freeze
Modern construction is better insulated than old, but the same three places still catch people out.
Loft runs where insulation has been laid under the pipe rather than over and around it, so the pipe gets the cold and none of the warmth from the house.
Garages and integral stores, unheated and often carrying the feed to an outside tap.
Outside taps with no internal isolator and no means of draining down before the first hard frost.
If a pipe has already frozen, shut the water off, keep any naked flame well away from it, and call us. With plastic pipe in particular the damage often does not show until it thaws.
Genuine 24/7 emergency plumbers for Cambourne
Round the clock cover means a person answers, an engineer is allocated and you get an honest arrival time rather than a comforting one, 365 days a year. Cambourne is a fair run from our Stevenage base, so we will always be straight with you about how long that takes and what to do while you wait.
We turn up with fittings, valves, flexible connectors, cylinder parts and pipe, which handles most emergencies first time. Where a permanent repair needs something we do not carry, we make the property safe and watertight, explain plainly what it needs, and come back to finish it.
Trusted & Accredited Professionals
Planning: almost nothing in the way here
There is one listed building recorded in the whole of Cambourne parish, Great Common Farmhouse in Upper Cambourne, which is Grade II. We found no conservation area designation inside the town itself.
For plumbing and heating that is unusually simple. Flue positions, external condensate routes and outdoor unit siting here are normally governed by permitted development limits and by estate management arrangements or covenants, rather than by heritage consent. If you are not sure what your plot deed says, check the covenants rather than worrying about listed building rules.

Frequently Asked Questions
How hard is the water in Cambourne?
Cambridge Water’s published figure for the Coton zone, Z6, which covers Cambourne parish, is 317.8 mg/l of calcium carbonate for 2025/26. That is above the 300 mg/l line normally used for very hard water. It is the company’s published zone figure rather than a measurement from your property.
My hot water goes warm then cold. What is that?
On a combi in water this hard, it is very often a scaled up plate heat exchanger. Heating works fine, hot water does not. We will confirm it properly rather than guessing, and we will tell you whether it is worth descaling or replacing.
My house has plastic pipe, not copper. Is that a problem?
No. Plastic barrier pipe run in push fit from manifolds is normal in stock of this age and it performs well. It does change how a leak is traced and repaired, which is why we use proper detection kit rather than lifting floors speculatively.
Who is responsible for the water pipe outside my house?
From the boundary into your home the pipe is yours, including repair costs. Cambridge Water supplies the mains water and Anglian Water handles sewerage, and Anglian Water took over the pumping stations here on 8 October 2016.
Do you charge more at night or at weekends?
Out of hours work is charged at a different rate, and we tell you what that rate is on the phone before we set off.
Are there planning restrictions on flues and outdoor units here?
Very few compared with the older towns we cover. Cambourne parish has a single listed building, Great Common Farmhouse, and we found no conservation area inside the town. The things to check are permitted development limits and any estate covenants on your plot.
