Water Infrastructure Risk Assessment Guide
Most building managers don't know the condition of their water systems. This guide explains why that matters and what to do about it.

What’s Inside the Guide
- The hidden cost of unassessed water infrastructure and why reactive-only maintenance is not a strategy.
- What a Water Management Risk Assessment covers, from incoming supply and cold water storage through to drainage, water hygiene and compliance indicators.
- The compliance obligations that already apply to your building, including ACOP L8, HSG274 Part 2 and, for social housing providers, Awaab's Law.
- How to present water infrastructure risk to your board or insurer, with a documented record that holds up to scrutiny.
- How to use the assessment to move from unknown risk to documented condition, and what that means for maintenance planning and budget forecasting

Why This Matters
Water-related problems in managed buildings do not arrive with a warning. A slow leak behind a riser. A cold water tank that has not been inspected in years. Isolation valves that have never been tested. None of these are visible risks. They are unknown ones, and unknown risks cannot be managed, budgeted for, or reported on.
They surface as emergencies.
Most of the cost associated with water infrastructure failure is not caused by the water itself. It is caused by delay, inconclusive investigation, fragmented contractor management and the absence of any documented record of what was checked and when.
A Water Management Risk Assessment converts that unknown risk into a documented baseline: a clear picture of what is present, what condition it is in, and where attention is needed before something fails.
What Our Customers Say
Shout out to Luke and Fraser. Brilliant lads who knew what they were doing. Had ongoing problems woth British gas and loads of people been to the property but we're useless then these lads diagnosed and fixed the leak with minimal damage all within 1 hour. Well done 👏
My insurance company sent SOS to fix a leak in my ground floor kitchen ceiling. I was delighted that Calvin showed up because he was also sent three years ago to detect a leak in my 1st floor hallway ceiling. At that time used a camera on a pole to he take numerous photos of my roof that pinpointed a large leak there. I saved a lot of money with my roofing company by supplying them with Calvin’s photos before they started work. See my review below. This time he came with colleague Tobias, and they quickly found the kitchen ceiling leak and repaired the pipe. Unlike the emergency plumber who told me last week that he would have to cut open a large section of my kitchen ceiling (and cause a lot of damage), Calvin and Tobias carefully pulled up the old carpet upstairs above the leaking pipe and unscrewed the floorboards (which hadn’t been pulled up since the house was built in 1924!). When they finished repairing the pipe, they refitted the floorboards and carpet with no damage. These are very efficient, knowledgeable and polite workmen, so I again highly recommend them!
The two engineers worked well together in some cold wet Welsh weather. After locating the leak, around the stopcock in the back garden, the leak was fixed, and all tested. Well done thank you.
Chris came out to detect a leaking central heating system which has caused considerable damage and has left us with no hot water or central heating for over a week, the insurance company appointed SOS Leak Detection to find the leak beneath the floor boards, Chris arrived exactly on time and explained what he was going to do, within a short space of time he had found the exact location of the leak and removed the flooring etc., he then repaired the damaged pipe and turned the heating system back on. Chris was very professional throughout and is a credit to the company.
