A major regional chain, Arnolds Keys, has joined OnTheMarket.

The firm has eight residential branches across Norwich, Norfolk and north Suffolk, and claims to be the largest independent estate agency both in Norwich and across Norfolk.

A partner is Jan Hÿtch, who was a particularly impressive President of the NAEA in 2013/2014, and is also a chartered surveyor.

The firm will now be advertising all of its properties for sale and to rent at OnTheMarket and Rightmove.

It previously listed on Rightmove only.

OTM announced in January that the level of overall support for the portal had risen beyond 6,500 estate and letting agent offices across the UK, an increase of more than 50% compared with the same time last year.

The figure consists of contracted offices and agents who have signed a Letter of Intent to join OTM when total support reaches 7,500 offices – which is OTM’s next major milestone.

Jan Hÿtch said: “We’re confident that OTM will continue to grow throughout 2016 and will build on the excellent performance it achieved throughout last year.

“The website is a great place to display our clients’ properties and we look forward to working with the UK’s only agent-owned, agent-controlled portal.”

OTM boss Ian Springett said: “We welcome this successful and multi-branch firm.

“It’s been a fantastic start to the year at OTM, with record traffic levels achieved in January, record leads for agents and a record number of recruited offices since launch.

“We look forward to welcoming many more new agents throughout 2016 and continuing to expand our property stock and our membership.”
