Case study: a hot-water return leak in a London care home boiler room
At a London care home, the engineer found a continuous leak on the hot-water secondary return in the boiler room. It was thought to contribute to damp in the basement, but the investigation did not establish it as the only cause.
A one-hour hot-water isolation window was agreed around the residents, allowing a pump union and washer repair. Pressure testing and retesting were not permitted on the visit. The report recommended monitoring the damp and addressing other observations, including absent boiler pressure and outside pooling. It does not establish that the basement dried or that every water problem was resolved.
What to mention when you call about a care home leak in Greater London
Very hard water in Greater London
Greater London’s water is very hard, at 280 to 360 mg/l, so limescale builds up inside hot-water pipework, cylinders and heating circuits. Mention any heating or hot-water symptoms when you call.
Heating and hot water leaksWho repairs the supply pipe under a care home’s grounds?
The supply pipe from the boundary stop tap into the building is the owner’s to repair, including under a car park or garden. Care homes are business customers, so a leak allowance goes through your water retailer.
Report a leak on the public side to Thames Water or SES Water.
Water mains leaksCare groups with homes in more than one London borough
If your care group runs homes across several London boroughs, give ADI every postcode on the first call and discuss how the visits could be arranged.
Managing leaks across several homesListed and conservation-area care homes in London
If your care home occupies a listed building or a property in one of London's conservation areas, let ADI know when you call. Planning constraints may affect how access and any remedial work is approached, and the investigation can be scoped accordingly.
Green upgrades for London's heritage homesWhere Thames Water’s responsibility ends for London care homes
Thames Water is responsible for the water main and the pipe up to the boundary stop tap. From that point, the supply pipe into the building is the property owner's responsibility to maintain and repair. If your care home has a suspected leak on the supply side, mention this when you call.

Leak detection equipment
used in care homes
ADI’s engineers choose between acoustic detection, thermal imaging, tracer gas, moisture mapping, pressure testing and inspection cameras to suit the pipework and building. No single instrument finds every leak.
About our detection methodsAcoustic leak detection
Acoustic leak detection uses sensitive listening equipment to help an engineer locate the sound of escaping water, including beneath ground and floors.
Thermal imaging for leak detection
Thermal imaging uses a camera that shows surface temperature differences, which can help an engineer investigate heating pipework and moisture patterns.
Tracer gas leak detection
Tracer gas leak detection uses a specialist gas mixture to help trace a leak from a suitable isolated pipe to a detectable point at the surface.
Moisture mapping
Moisture mapping takes measurements across walls, ceilings or floors to build a picture of where moisture is concentrated in the building.
Pressure testing pipework
Pressure testing checks suitable sections of pipework to help establish which part of a heating or water system is losing pressure.
CCTV drain surveys and inspection cameras
Drain cameras and borescopes give the engineer a view into accessible drainage and concealed spaces that cannot otherwise be seen.

Common questions about care home leaks
in Greater London
These answers cover ADI’s coverage, supply pipe repairs, water supply and planning a visit around residents for care homes in Greater London.
Ask ADI a questionDo you cover the whole of Greater London?
ADI’s nationwide leak detection service includes Greater London, and the team confirms availability for your care home’s postcode when you call. The towns on this page are examples.
Can the investigation work around our residents?
Yes, access and any testing interruptions are agreed with the home's staff before the engineer arrives, and your team approves any isolation. When you call, tell ADI about occupied rooms, visiting times and any services that must stay on.
Who repairs a leak on the supply pipe under our grounds?
Usually the property owner, because the supply pipe running from the boundary stop tap into the building is the owner's to maintain and repair. Thames Water is responsible for the water main and the pipe up to the boundary stop tap. Care homes are business customers, so any leak allowance is claimed through your water retailer.
Which water company supplies our care home in Greater London?
Thames Water supplies most of Greater London, and SES Water supplies parts of south London, including areas around Morden and South Croydon. Check your water bill or contact your water retailer to confirm which company supplies your site.
Does Greater London's water hardness affect pipework?
It can, because Greater London's water is very hard, and limescale build-up is a possibility in older hot-water pipework, cylinders or heating circuits. Mention any hot-water or heating symptoms when you call and the investigation can cover those systems.
Are the engineers DBS checked?
Ask ADI to confirm the attending engineer's current checks and documentation when you book, and share your home's safeguarding, escort and visitor requirements. The visit can then be arranged to meet them.
