Mr Houchen recorded a landslide victory, receiving 121,964 votes compared to Labour rival Jessie Jacobs, who managed 45,641.
The result came after Prime Minister Boris Johnson had visited Hartlepool to congratulate Jill Mortimer on becoming the town’s first Conservative MP since the constituency was established.
And there was further joy for the Tories after Steve Turner became the new Cleveland Police and Crime Commissioner (PCC).
Mr Turner received 74,023 votes, which was almost double that of Labour rival Matthew Storey, who managed 39,467.
Independent Barrie Cooper came third with 16,667 votes, while Liberal Democrat candidate Chris Jones received 6,540.
