Received an email from my tenants today asking for a rent reduction on the flat they rent from us in London. They both travelled back home to their respective parents elsewhere in the UK before Christmas and have not returned to the flat. They say that contributing to rent and bills at home is making meeting the rent difficult. Does anyone know if, under the current lockdown rules, they are allowed to travel back to their primary residence - the flat- or whether they have to stay put at their parents? I’ve looked at Govt. website but it’s not clear to me. Thanks.
