The announcement came after the party Reform revealed it would target Green-voting areas for the centres.
Reform UK said it would build the facilities in remote areas of the country as part of plans to detain up to 24,000 people within 18 months.
The party also said it would not put detention centres in areas where its own party has an MP, or where it controls the council.

Reform would need to seek a legislative consent motion to have the Bill’s provisions on planning apply in Scotland as planning is a devolved matter.
However, given the likely make-up of Holyrood, with the SNP polled to take a “landslide majority” it would be unlikely to receive backing from MSPs.
Thomas Kerr, Reform UK councillor for Shettleston told The Herald that the party would look to “amend legislation” to ensure they could pass laws introducing migrant detention facilities in Scotland if Farage wins the next UK general election.
Reform’s migrant detention facilities are part of the Illegal Migration (Mass Deportation) Bill and under the party’s plans, people with no lawful right to remain in the UK would be placed in the centres and would not be able to leave.

They would stay there for about two weeks before being deported.
The legislation would also give the Home Secretary new powers to stop councils blocking the opening of detention centres.
Kerr said: “A Reform Government would first seek a legislative consent motion from Holyrood, but if rejected by Holyrood, then we’d look at amending legislation to ensure the change happens.
“This is a national security emergency and we can’t allow foreign criminals to walk our streets any longer. Reform will take action and we’ll allow others to pontificate why they back strangers over Scots.”

Scottish Green co-leader Ross Greer said that Scots will not take kindly to this “bullying”.
Greer added: “Reform UK are now openly threatening voters.
“Scots will not take kindly to this kind of bullying.
“Offord and Farage want to turn this country into Donald Trump’s America, a place where those who oppose their hateful politics are threatened and attacked.”

The response comes after Greer challenged Reform UK’s Scotland leader Malcolm Offord, last week on the STV Leaders Debate.
Following the debate, the Scottish Greens proposed the introduction of an “Offord tax”.

Greer continued: “People across Scotland are ready to reject this vile outfit of ex-Tories, conspiracy theorists and billionaires.
“This latest threat shows that the best way to do that is by voting Scottish Greens on your regional, peach-coloured ballot paper.
“The fact that they are led in Scotland by a multimillionaire lord who owns six homes, six boats and five cars tells us everything we need to know about these chancers. Reform has no interest in making people’s lives easier.
“Compare that to the Scottish Greens. We delivered free bus travel for young people. We scrapped peak rail fares. And we are prepared to go even further, with free bus travel for all and a childcare system that families can actually afford.
“All over Scotland this vote will go down to the wire between the Scottish Greens and Reform. Every ballot will be crucial. Let’s show that hope and unity will always defeat hate and division.”

First Minister John Swinney said: “I simply think this is an illustration of the dangerous nature of Reform’s politics.
“If there was an illustration of an attempt to divide communities, that policy announcement epitomises it.
“That is division, divisive politics, in practice and I’ve made it clear, that’s why I’ll have nothing to do with Reform, that’s why there will be no place for Reform in the governance of Scotland, if I become the first minister and I have the majority in the Scottish Parliament, because we cannot go down this route.
“It is the route to division, to disorder and it divides our communities and I will have none of it.”
