Cornerstone Projects Ltd

Cornerstone Projects started in 2004 when it’s founder, Duncan Phillips, came up with the idea of offering Underground Utility Searches whilst managing a small engineering design team in his previous role. His team regularly had to contact the utilities for their plans and he soon realised how much hassle and time this took. He quickly turned this idea into action, and with over 35,000 searches completed to date, has built systems and internal processes that are the envy of the industry.


We now provide hundreds of desktop underground utility reports (sometimes known as statutory undertakers reports or STATS reports) per week for anyone needing to locate buried underground utilities such as electricity cables, gas pipes, water mains, sewers etc. This may be necessary at the acquisition, feasibility, design or construction phase of a project.

We collate information from all the relevant utility companies on your behalf and compile a pack of information and plans for each site – check our sample report here.


It is a requirement by the Health and Safety Executive to obtain information on buried utilities, services and apparatus that may exist before starting work – check the HSE advice here.

Knowing the whereabouts of buried plant will also help to avoid potentially expensive damage to underground plant as well as the related cost of the delay and disruption.


See which types of companies benefit from this service in our sectors and clients sections, whom we deal with day to day.

We provide a comprehensive utility search including water, gas, electricity, sewers, telecoms, petroleum pipes and cable. We can also cover any special requirements you may have – for example, mining reports.

We also offer a host of additional searches including help with utility connections, disconnections/diversions, capacity checks and Section 50 applications.
