Leak Detection
Leaks in underground drainage systems, storage tanks, and containment infrastructure can go undetected for months or years, allowing contamination to enter the ground and potentially reach nearby watercourses. By the time a leak becomes visible on the surface, the environmental and financial consequences can already be significant.
GreenSpark provides leak detection services for commercial and industrial sites across the UK, helping businesses locate hidden leaks to avoid the risk of them becoming pollution incidents, regulatory problems, or costly remediation projects.
Why Leak Detection Matters for UK Businesses
Underground infrastructure deteriorates gradually and often without obvious signs. Drainage pipes, storage tanks, and bund linings can all develop defects over time, and the contamination that results can move through soil and into groundwater before it becomes apparent at the surface.
Regulators, including the Environment Agency, expect businesses to take reasonable steps to prevent pollution, including knowing the condition of infrastructure that carries or contains pollutants. Where a permit is in place, demonstrating active control of pollution sources is typically an explicit requirement. Where no permit exists, the general duty to prevent pollution still applies, and an undetected leak represents a failure to meet it.
The cost of remediating contaminated land and groundwater is almost always substantially higher than the cost of detecting and repairing the leak that caused it. Leak detection forms part of managing the assets your site depends on.
Why choose GreenSpark for Leak Detection?
Leak detection tailored to your site
GreenSpark assesses each site to determine the most appropriate detection method for the infrastructure and type of leak involved. Findings are documented clearly, with results reported alongside the context needed to take informed action.
From detection to resolution, under one roof
Identifying a leak is only the first step. Because GreenSpark provides asset testing and certification, drainage mapping, surveying and remediation, and planned maintenance, the move from identifying a problem to resolving it can happen without delay and without the overhead of briefing a separate contractor. This supports a clear audit trail from detection through to any follow-on work, including what was found and what actions were taken.
Nationwide coverage
GreenSpark operates across the UK, supporting businesses with single sites and complex multi-site estates. We can mobilise quickly, coordinate leak detection programmes across multiple locations, and deliver a consistent approach and clear, comparable reporting wherever you operate.
Assess your compliance today
How leak detection fits into your compliance programme
Leak detection is most effective when it forms part of a broader programme of asset management and environmental compliance. On its own, a detection survey confirms conditions at a point in time. When that data feeds into asset testing schedules, drainage mapping and planned maintenance programmes, it becomes part of a continuous approach to managing infrastructure integrity and preventing pollution. For businesses with ESG commitments or sustainability reporting requirements, documented leak detection activity provides auditable evidence that environmental responsibility is embedded in site operations rather than managed reactively.

FAQs about our Leak Detection
What is leak detection?
Leak detection is the process of locating leaks in underground or concealed infrastructure such as drainage systems, storage tanks, and containment assets. It uses specialist methods to find leaks that are not visible from the surface, allowing businesses to address problems before they cause contamination or compliance failures.
Why does my business need leak detection?
Underground infrastructure deteriorates over time and leaks can develop without any visible signs on the surface. Without detection, contamination can spread through soil and groundwater unnoticed. Regulators, including the Environment Agency, expect businesses to take reasonable steps to prevent pollution, and leak detection provides evidence that underground assets are being actively managed. For sites with an environmental permit, it supports compliance with the conditions of that permit. For all businesses, it reduces the risk of enforcement action and provides documented evidence of responsible asset management.
What types of infrastructure can GreenSpark test for leaks?
GreenSpark provides leak detection for drainage systems, storage tanks, bunds, and other containment infrastructure. The approach is tailored to the specific assets on your site and the type of leak suspected.
How does leak detection support environmental compliance?
Leak detection provides the evidence base to confirm that underground infrastructure is not releasing contaminants into the environment. It supports regulatory inspections, audit processes, and permit requirements by demonstrating that your business is actively managing the integrity of its pollution control assets.
Can leak detection support our ESG or sustainability reporting?
Yes. Documented leak detection activity, particularly when integrated with asset testing, drainage mapping, and maintenance records, provides auditable evidence of proactive environmental management.
Do you carry out leak detection for multi-site businesses?
Yes. GreenSpark supports businesses with single sites and large multi-site estates across the UK. We can coordinate leak detection programmes across multiple locations, providing a consistent approach and clear, comparable reporting across your entire operation.
