Knowledge Base
Find the right guidance by starting with what you have noticed, not by guessing the service or technology you need.
This hub brings together symptom guides, practical checks, investigation methods, comparisons, FAQs and real case studies so homeowners, landlords, managing agents and commercial property owners can decide what to read next.
Start Here
Most visitors arrive with a symptom, a confusing result or uncertainty about the next step. Choose the closest route below and follow the links that match your situation.
Popular Symptoms
Symptoms rarely prove one cause on their own, but they are usually the best starting point. These pages explain what each sign may mean, what else could cause it and when investigation may be appropriate.
Understand when repeated pressure loss may indicate a heating circuit leak or another sealed-system fault.
Read symptom guide HeatingGuidance for pressure loss affecting radiators, concealed heating pipework or sealed heating systems.
Read symptom guide Water supplyLearn what a moving meter can mean when taps, toilets and appliances should be off.
Read symptom guide Water supplyCheck what unexplained water use may indicate before assuming where the leak is located.
Read symptom guide DampExplore common causes of damp patches, including condensation, water ingress and concealed pipework.
Read symptom guide Hidden leaksUnderstand why leaks below concrete or screed need careful investigation before access work is planned.
Read symptom guidePopular Guides
Guides are for learning, not selling. Use them when you want to understand a safe check, interpret a result or gather better information before asking for advice.
Start with safe checks for common hidden leak symptoms, then decide which more specific guide or service route fits.
Read guideUse safe surface checks to interpret damp flooring, meter movement, pressure loss and floor-level leak symptoms.
Read guideReview usage, estimates, meter behaviour and visible causes before deciding whether a high bill may need leak detection.
Read guideA practical guide to checking meter movement, interpreting what you observe and deciding what should happen next.
Read guideLearn how to record meter readings, recognise flow indicators and understand what reading changes may suggest.
Read guideLearn where to look for your internal stop tap, how to identify it safely and how it can support leak checks.
Read guideLearn which valves to use, what not to force and how isolation results can support water leak checks.
Read guideLearn how to record boiler pressure readings, interpret pressure-loss patterns and decide what help may be needed.
Read guideLearn how to check whether a toilet is passing water and whether it could explain meter movement or high usage.
Read guideInvestigation Methods
You do not need to choose a technology yourself. These pages explain what each method helps investigate, where it has limits and why several methods may be combined.
Useful for temperature patterns linked to heating leaks, hot water pipework and moisture-related clues.
Learn methodOften used for concealed or buried pipework where a suitable pipe section can be isolated for testing.
Learn methodSupports investigations where escaping water may create detectable sound in pressurised pipework.
Learn methodHelps understand where water has travelled through floors, walls, ceilings and finishes.
Learn methodLearning Paths
These paths connect symptoms, guides, services and technologies so you can move through the Knowledge Base without guessing which content type you need.
Start with the symptom, perform the safe meter check if appropriate, then review mains water investigation routes.
Begin with the pressure-loss symptom, then review heating leak detection and the technologies commonly used.
Compare visible symptoms with damp guidance, moisture investigation methods and trace and access information.
Use the comparison hub when you need to understand the difference between symptoms, services and investigation methods.

These answers help you decide where to go next if several pages appear relevant.
Start with the symptom. Pressure loss, a moving water meter, damp patches and ceiling stains usually provide a clearer route than trying to choose a service name first.
No. The Knowledge Base can help you understand symptoms and safe checks, but concealed leaks usually need a property-specific investigation before the source can be confirmed.
No. Technologies are selected after reviewing the symptoms, property construction, pipework and likely leak location.
If the symptom continues, the source is concealed, the meter keeps moving, heating pressure keeps dropping or water damage is spreading, professional investigation may be appropriate.
Need Professional Help?
If the Knowledge Base has helped narrow the issue but the source remains concealed or uncertain, send the property details, symptoms and any safe-check results. A specialist can advise the most practical next step.
Understand the main investigation routes for different leak symptoms.
Check service coverage across London and Southern England.
Read concise answers about surveys, reports, technologies and booking.
Review published investigations from real properties and commercial sites.
