Why look beneath the surface?

Drainage liabilities can equate to significant and unforeseen costs, sometimes up to 10% of capital value. Therefore, it is highly beneficial to understand all associated risks, particularly at the pre-acquisition stage.

Since 1960, we have been the UK’s leading specialist for drainage services in Transactional Due Diligence. So, we understand that a standard CCTV survey is not enough to gain a full understanding of financial liabilities.

Unlike our competitors, our inspections ensure every liability linked to the drainage system is assessed. This includes environmental risk, legal compliance and suitability as well as structural condition. These areas are frequently overlooked, yet can present issues that are costly, disruptive and can potentially cause reputation damage.

In 2024 alone, approximately 30% of drainage defects we found related to environmental risk and the remedial costs of these were valued at over £8m in total. This highlights the importance of assessing all associated factors.

In addition to analysing the drainage system as a whole, we provide honest, practical, commercial advice for remedial costs and repairs, in addition to 5-year maintenance plan.

By having a complete understanding of the drainage system, it means all risks and potential problems are addressed, and associated costs known, to allow for better informed, strategic decisions to be made.
