For the 2023 Periodic Review of Westminster constituencies, which redrew the constituency map ahead of the 2024 United Kingdom general election, the Boundary Commission for England opted to combine the unitary authority of County Durham with the Tyne and Wear boroughs of Gateshead, South Tyneside and Sunderland as a sub-region of the North East Region, with the creation of a cross-county boundary constituency named Blaydon and Consett, resulting in the abolition of North West Durham. The reconfigured Sedgefield constituency was renamed Newton Aycliffe and Spennymoor. The Borough of Darlington was included in a Tees Valley sub-division.^[2][3]

The following seats resulted from the boundary review:

Containing electoral wards in Darlington

• Darlington
• Stockton West (part also in Stockton-on-Tees)

Containing electoral wards in County Durham

• Bishop Auckland
• Blaydon and Consett (part also in Gateshead in Tyne and Wear)
• City of Durham
• Easington
• Newton Aycliffe and Spennymoor
• North Durham

Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to retain Durham's constituencies for the 2010 election, making minor changes to realign constituency boundaries with the boundaries of current local government wards.
