Wembley High Technology College and East Lane Primary School

• Tested both sites in one day, 10 August 2026, during the summer break so there was no disruption to the schools.
• At Wembley High Technology College tested the Main Block (9 electrodes), the IT Cafe and Sixth Form (3 electrodes) and the Maths Hall (2 electrodes), and inspected the roof networks, fixings, bonds and any new plant.
• At East Lane Primary tested Blocks A to D including the Dining Hall, 24 electrodes in all, with the 3 pole fall of potential method used wherever the ground allowed.
• Reported every individual reading against the 10 ohm per electrode convention carried from the previous certificates, and calculated the parallel combined value for each structure: 1.15 ohms for the Main Block, 1.60 ohms for the IT Cafe and Sixth Form, 5.04 ohms for the Maths Hall.
• Flagged electrode E5 on East Lane Block C at 43.7 ohms as Attention. It has read in the mid 40s two years running, so we recommended a rod extension or supplementary rod before the 2027 test and offered a price.

Both sites passed. Two certificates were issued on 2 September 2026, one per site in place of the old seven, with readings, combined values, the ESE note, the instrument reference and the next due date of August 2027. The Block C electrode is on record as a planned remedial rather than a surprise failure next year.
