Mobility retail chains with stores in Wales will be limited on how much business rate relief they are eligible for.
Multiples based in Wales will be limited to claiming relief on just two of their shops based in each council.
There are barely a handful of mobility chains in Wales with Bush Healthcare dominating the South East with its 10 stores and Ableworld boasting a number of stores dotted around Wales and the Borders.
The Welsh Government hopes the plans will save £7m which will be diverted to provide relief for nurseries and other companies that provide childcare in Wales.
Recently the Welsh Government announced a £10m business rate relief fund to ease the burden on high street firms who are facing rising rates due to a revaluation of their premises.
But experts have warned that rural shops in Wales face huge challenges and could be forced to close under the pressure of April’s business rate hike.
The comments come as it was revealed that £52m of business rates were unpaid in Wales in 2016.
The Welsh Retail Consortium, which represents shops, told the BBC: “Retailers of all sizes pay disproportionate amount in business rates, and therefore, we welcome all possible relief.
“However, reliefs and exemptions are a sticking plaster approach to an outdated system.
“The burden needs to come down for everyone, and business rates requires fundamental reform to make them fit for the 21st Century.”
