Barrie Cotton

Barrie Cotton

Interim Head of Maintenance

Started my career in Housing Management as a Homeless Persons and Domestic Violence receptionist in Manchester. This was my introduction to clients with often serious mental health and addictive behaviour, as well as serious violence abuse from family members, and was a real eye opener to some very harsh realities some people endure. Although challenging, I was always keen to offer assistance to the clients when they were often at their lowest ebb and where was able to secure accommodation for them either in emergency hostels or alternative permanent housing.

Following on from this I became an Estate Manager covering a generic role managing estates in Manchester. I was promoted quite quickly into management roles and loved being a Team Leader of often complex staff in harsh estate management environments. I was a Principle Team Leader for 15 years before taking a leap into a different life and moving to London to study holistic and natural medicine.

Whilst in London I became a contract project manager working in Asset Management in both Haringey and Hackney, where I was part of the team implementing Arm’s Length Management Organisation (ALMO) so each council could successfully bid for £100’s millions in additional borrowing for home improvements called “Decent Homes Program” a Government initiative to modernise and improve council stock across the country. I then became the Governance Manager for the ALMO board in Hackney, eventually moving on to general projects implementing new empty property management process, and options appraisal for investment opportunities in Hackney for new social housing and more recently the implementation of Green cycling initiatives in the borough.

This was all great new experience, which played to my desire to improve quality and service delivery to customers.
