A utility survey uses specialist equipment to detect and trace buried services such as electricity, gas, water, telecoms and drainage, so you can see what’s beneath your site before work begins.
The results are captured into clear survey drawings (typically CAD/PDF), giving your team a reliable reference for planning excavations, avoiding clashes in the design stage, and reducing the chance of costly delays caused by unknown or mislocated utilities.

Utility surveys are typically needed at two key stages: early in a project to map services across the site, and right before excavation to reduce the risk of a utility strike.
If you’re planning, designing or pricing works, a site-wide utility survey gives you a clear picture of what’s underground across the full area. This helps you avoid design clashes, plan routes for foundations and drainage, and reduce expensive last-minute changes once works are underway.
If you’re about to dig, drill, trench or pile, a pre-excavation clearance survey focuses on the specific work zone so you can break ground with greater confidence. By identifying utilities where you’re working, it helps you reduce strike risk, minimise delays, and keep teams safer on site.
Our utility surveys are delivered in line with PAS 128 — the UK specification for underground utility detection and mapping. This gives you a clear, consistent standard for survey method and reporting, helping you make safer decisions, reduce risk, and demonstrate due diligence on site.
Learn More About PAS 128To get a clear idea of what's beneath the surface, we deploy cutting-edge technologies such as EML and GPR to do a type of ultrasound of the ground. Used together, they give a fuller picture of what’s underground and increase the reliability of the survey.
EML is excellent for tracing metallic pipes and live cables. We also use sondes to trace non-metallic drains when access is available.
GPR detects anomalies in the ground which allows us to locate both metallic and non-metallic features— including plastic pipes and ducts as well as providing an estimation of depth.
Why us
From our main offices in Hertfordshire and Birmingham, we've carried out thousands of utility surveys across the UK. Browse our project case studies below or get in touch with our team to discover how we can help you.
Our team travelled north to the coastal site and spent five days conducting a full underground utility survey.
We carried out a comprehensive PAS128 utility survey, mapping existing infrastructure across the entire estate
