3 Railway Terrace, New Herrington, Houghton Le Spring, DH4 7BD

This property is located in New Herrington, Houghton Le Spring, within the DH 4 postal district of the City of Sunderland, formerly part of the Houghton‑le‑Spring constituency.

The locality of New Herrington, Houghton Le Spring, is situated within the historic Houghton‑le‑Spring parliamentary constituency that existed from 1885 to 1983. The constituency was centred on the town of Houghton‑le‑Spring and was part of the County Durham area before becoming incorporated into the City of Sunderland. It elected one Member of Parliament by the first‑past‑the‑post system. The constituency’s history reflects the administrative changes in the region over the past century, and the locality now falls under the modern postal district DH 4. Residents of New Herrington are therefore linked to the broader Sunderland community while retaining the local character associated with the former constituency boundaries.
