The Letmove portfolio encompasses over 450 properties across the Wakefield and South Leeds area.
Earlier this year Countrywide purchased Blundells, Spencers and Mike Jolly Estates, all based in South Yorkshire.
Richard Coxon, area manager of Countrywide residential lettings, said: “We are very pleased with the further expansion of our lettings business in the West Yorkshire area and to welcome the Letmove team into the Countrywide Group.
“Letmove operates successfully in this region with an established client base and we look forward to working with the team to grow and develop the business further.
“As one of the most affluent areas in the region, Wakefield residents have benefited from increased employment opportunities in the area and commuters can enjoy its close proximity to Sheffield, Leeds and Manchester.
“We see it as an area of continued growth that will offer some great opportunities for us to deliver our award-winning lettings services and products to a larger audience.”
John Hards, co-managing director at Countrywide residential lettings, added: “We plan to expand our lettings network even further in 2012, both organically and through acquisition, to ensure we continue our strong run of phenomenal growth.
“In addition to the opening of over 100 new start branches and the average of one acquisition per month we have also increased our team of passionate, driven and skilled lettings experts and we are delighted to welcome the lettings staff from Letmove to our ever expanding network.
“We are in a strong financial position to increase our reach so we urge business owners to get in touch to discuss what opportunities are available.”
