Freeholders and managing agents are overcharging leaseholders for the insurance of their flats, while also pocketing large commissions from the insurers. Campaigners for leasehold reform are calling on the government to crack down on the practice. Sir Peter Bottomley MP, the co-chairman of the All-Party Parliamentary Group on Leasehold and Commonhold Reform, says: “We believe unfair service charges cost leaseholders hundreds of millions of pounds each year with secret commissions on buildings insurance deals making up a large part of it. Regulators must do more to bring this corrupt practice against leaseholders to an end.”
