Renewable Energy Technical Site Surveys.

Independent technical surveys for solar PV, battery storage, EV charging and grid connection projects across the UK. Give your design and installation team the information they need, without sending an electrician or project manager to site.

UK-wide · Independent · Single Site to National Programme

What we survey

Four categories, one consistent process.

From single commercial sites to national rollouts, the scope is agreed before attendance so our surveyor captures the information your team actually needs.

Solar PV Surveys

Existing electrical infrastructure, proposed array and inverter locations, cable routes and design information.

Battery Storage Surveys

Existing supply, proposed BESS location, import and export considerations.

EV Charging Surveys

Supply characteristics, distribution equipment, proposed charger locations, cable routes.

Grid Connection Surveys

Technical site information to support feasibility studies and G99 applications.

Outsourced field team

An independent, white-label surveyor when you need one.

Additional survey resource without hiring another full-time employee, and without introducing a competitor to your customer.

Your customer stays yours

We do not sell to your customer, do not compete for the installation work, and don't contact them outside the survey visit.

White-label surveys

Our surveyor can attend acting on behalf of your business, and the report can carry your branding rather than ours.

Nationwide field team

Based in the North East, supporting projects across England, Scotland and Wales. Typically on site within 3-5 working days.
