SolarGridCheck is a free, independent tool for UK landowners and farmers who want to know whether their land could host a solar farm or battery storage project. Enter a location and it returns the nearest mapped 33kV+ substation, the published headroom and constraint flags where the network operator publishes them, and an indicative lease income range. It is a preliminary screen, not a live capacity check or a valuation. It uses public data from all six GB Distribution Network Operators, the government's Renewable Energy Planning Database and the NESO TEC register, and publishes free data pages on UK solar farm planning by county and the GB grid connection queue. Free for landowners: if a site looks viable and the landowner asks, SolarGridCheck introduces them to solar and storage developers, who pay a fee if a project goes ahead.
For most landowners the first question, "is there even grid capacity near me?", is the hardest to answer. The data exists, but it is scattered across network operators' maps and spreadsheets, the government's planning database and NESO's transmission records, and none of it is written for landowners. I'm a web developer, not a solar developer, and I built this so a landowner can get a realistic first read before spending months talking to developers.
