The drama series was filmed in several locations in the county and searches for Cornish properties have more than doubled since it first aired, property portal Rightmove said.

The series used several picturesque locations including Charlestown, Gunwalloe and Porthgwara and each has seen a spike in interest.

Last week a survey by Direct Line revealed Cornwall was the most popular location for holiday homes in the UK.

Local estate agents have also reported a ‘Poldark effect’ and have seen an increase in the number of viewings and sales since the programme began in March.

Brian Deacon is sales and marketing director for Linden Homes, who have a development near Charlestown, and he said more people had become aware of what Cornwall has to offer.

“Reservations and visitor levels have certainly increased since the TV series highlighted the beautiful local scenery,” he said.

“The ‘Poldark effect’ is definitely having an impact on sales and I’m not surprised as this particular corner of Cornwall is such a stunning part of the world.”

Other reports suggest a spike in tourists visiting the area and this is likely to continue following the broadcast of the final episode of the series last night. The show has attracted more than 8.5 million viewers to BBC One each week during its eight episode run.
