In January, after 21 months of the scheme being stalled, Rwandan President Paul Kagame suggested some money could be returned if no asylum seekers were sent to the country.
But Rwanda’s government later specified there was “no obligation” to refund the UK.
In Rwanda’s capital, Kigali, workers hired months ago to build housing for the asylum seekers expressed concern about Mr Starmer’s decision.
The scheme’s death could “badly affect our lives”, a worker at the Gahanga site told the BBC.
Employees on the site get paid between £1.80 and £6 per day – relatively good wages for construction workers in Rwanda.
Resident Mariya Nyirahabimana said the value of houses in her neighbourhood had increased significantly since construction started, but she feared that “poverty could come back” to Gahanga.
Since his party won last week’s election in a landslide, Mr Starmer has labelled the Rwanda scheme an expensive “gimmick” and pledged to instead focus on launching a new Border Security Command to tackle people-smuggling gangs.
Opposition to the bill has also came from other quarters over the past two years – the UK’s Supreme Court ruled the plan unlawful, human rights organisations branded it cruel and draconian, while dissenters within the Conservative Party pushed for amendments that would better protect the scheme from legal challenges.
The previous government said the scheme was aimed at deterring people from crossing the English Channel in small boats.
Illegal migration is one of the major challenges facing the UK government.
So far this year, more than 13,000 people have crossed the Channel in small boats.
The figure is higher than numbers for the same period last year, although in 2023 as a whole there was a drop compared to 2022.
Denmark had been mulling a similar deal with Rwanda, but it put the discussions on hold in January last year.
It said it wanted a more unified approach within Europe to tackle illegal migration.
