Acquisitions included Cambridgeshire-based estate agents Tucker Gardner, Hampshire-based Personal Homefinders and Curtis Bains in Manchester city centre.
Countrywide has acquired 100 lettings businesses throughout England and Scotland since 2007, investing over £100m in the process.
Nick Dunning, group commercial director at Countrywide, said: “These acquisitions significantly increase our regional footprint and fill in the geographical gaps in our portfolio.
“Current market conditions offer ongoing opportunities to acquire lettings businesses and scope to enter new markets as well as expand our presence in existing markets.
“The investments we make in our acquisitions are not only focused on the growth of our Countrywide Residential Lettings business within the group but also the growth of our people.
“Over the past four years our acquisitions have created circa 350 new jobs within the lettings sector, some of which have been the first stepping stones for many graduates’ in their future careers.”
Further acquisitions in 2014 included the portfolio of APW in Surrey, Jonathan Reese in Romsey, Nest in Nottingham, Acorns Residential in Kent, The Flat Managers in Cheltenham, Griffiths Charles in Worcester, Holmes Pearman in Basildon and Billericay, Duck & Hedges in South West London and Sewell & Gardner in Rickmansworth.
John Hards, managing director at Countrywide Residential Lettings, added: “Countrywide has a unique ability to grow businesses by ensuring they operate autonomously, retain their local heritage and benefit from Countrywide’s ongoing investment and support.
“For clients, Countrywide’s structure, scale and all-round property expertise enables it to best serve the needs of clients of all sizes; from private landlords to corporate investors.
“In line with our expansion strategy, we are very interested in talking to professional agents with single or multi-branch businesses almost anywhere in the UK.”
