Leasehold campaigners have taken their concerns about a lack of tenure information in property listings to the All Party Parliamentary Group (APPG) on Leasehold & Commonhold Reform.

The National Leasehold Campaign (NLC) has written to Rightmove again to press the portal to make it mandatory for agents to include tenure terms on their listings and has made APPG members Justin Madders and Sir Peter Bottomley aware of the complaint.

The portal told the NLC this week that there was an option for users to include leasehold terms after the activists warned agents that not including this information could breach Consumer Protection from Unfair Trading Regulations (CPRs).

Kendrick said it was not enough to just provide an option.

She said: “As the UK’s largest property advertising platform, you have a responsibility to ensure anything material that would affect a purchaser’s decision is disclosed at the earliest opportunity under CPRs.

“Inclusive of that is not only tenure but any other large fees.

“As founder of the NLC and trustee of the Leasehold Knowledge Partnership (LKP) I will escalate my concerns to the APPG on Leasehold & Commonhold Reform to raise this with government ministers.”

She urged Rightmove to work with the NLC to ensure agents conform with the CPRs and Codes of Practice by including leasehold details on listings.

Zoopla and OnTheMarket also encourage agents to include tenure terms, but as with Rightmove neither make it mandatory.

A spokesperson for OnTheMarket said: “OnTheMarket encourages all of our estate agent customers to include details of the tenure in a dedicated data field.

“Whether a property is leasehold or freehold is important information for consumers and it is the recommended code of practice that agents include this specification.”

It comes as the Law Commission is today set to reveal its recommendations on reforming how leaseholders can extend their lease or buy their freehold.
