Is there a link anywhere about how that works? I thought they could only have one home, either in London or the constituency, for which they could claim expenses?
I don't have a direct link to the rules but it's apparently allowed. According to this report in The National:

As an MP with a constituency outside London, he is entitled to claim accommodation costs for staying in the capital.
According to his submissions to the Independent Parliamentary Standards Authority (Ipsa) – which sets MPs’ pay and expenses – until 2017 he was claiming between £8,000 and £9,000 a year in “associated costs,” such as utility bills and service charges on a property he owned.
But from 2018 his claims rose to £22,000 a year after he moved into a rented property.
At the same time, his declaration in the Register of Members’ Interests showed that from November 2017 he was collecting more than £10,000 a year renting out a residential property in London.
According to the Mirror, the property is a flat in a plush mansion block in Battersea, where he had previously been living.
The arrangement is permitted under Ipsa rules. An Ipsa document in 2017 acknowledged that such arrangements could be controversial but advised against any change to the rules.
“We recognise that there can be a perception of personal gain if an MP receives rental income from their own property while living in an Ipsa-funded flat,” it said.
“However, our view has not changed that an MP’s personal financial situation is not a relevant ‘test’ for whether they should receive support from Ipsa.
“We do not want to judge an MP’s private arrangements and whether or not they should live in a property they own."
