How to Interpret the Map — Layer Key
Local distribution substation
Light-purple circular point symbol; click to inspect published transformer and voltage fields. Zoom to level 13 or closer.
Point markerWhat This Layer Shows
The Distribution Substations layer selects local distribution-level records from Northern Powergrid’s public Substation Sites List. It is distinct from primary, BSP and GSP sites.
Published attributes may include substation name, mounting type, transformer rating in kVA, primary and secondary voltage, upstream substation and site reference. Fields describing a very small number of customers can be redacted by the publisher.
The layer becomes available at zoom level 13 to avoid showing an incomplete national-scale sample. The map requests pages of records for the area in view and displays a warning if more than 1,000 site records are returned.
Why It Matters for Your Site or Property
Local substations provide useful context for property development, business premises, retrofit, low-carbon heating and electric-vehicle charging feasibility.
Their proximity does not prove which substation serves a building, network capacity for additional load or a feasible connection route.
Planning and Property Impact
Use the layer to identify nearby publicly listed assets for further enquiries with the electricity network operator.
For new connections, increased loads or site excavation, obtain current operator records, technical advice and the required safety surveys.
How to Interpret This Layer
- 1Move the Maplify map to Northern Powergrid’s service areas and zoom to level 13 or higher.
- 2In Map layers, open Electricity Networks > Northern Powergrid and select Distribution Substations.
- 3Hover over a marker for basic information, then click it to open Map Point Details and read all available attributes.
- 4Zoom further into dense urban areas if the map warns that the current area exceeds its displayed record limit.

Planned refresh frequency
On-demand API requests by visible map area; operator controls publication frequency.
Important Limitations
- The provider publishes around tens of thousands of distribution-site records; a dense viewport may exceed the 1,000-marker display cap.
- Coverage is limited to Northern Powergrid service areas; it is not a full British electricity asset inventory.
- Customer counts and related fields may be deliberately redacted. Blank fields should not be interpreted as zero load or zero customers.
- Mapped points are not safe digging plans and do not establish spare capacity, wayleaves or rights to connect.
Common Use Cases
Property and land researchers
Review indicative electricity distribution infrastructure near a candidate site.
EV infrastructure planners
Identify nearby mapped substations before commissioning a formal electrical capacity study.

Frequently Asked Questions
Why does the distribution layer only show at high zoom?
There are many local distribution sites. Maplify starts loading them at zoom 13 to make local results more useful and avoid a truncated wide-area map.
Can I determine my property’s supplying substation?
No. Map proximity cannot establish the serving circuit or the substation assigned to a particular property.
Are transformer ratings the same as spare capacity?
No. A transformer’s rated size and a connection’s available headroom are different things. Confirm capacity with Northern Powergrid.
