Our History

The history of John Planck Ltd, John Monaghan and HAF is all intertwined – the success of the company as it stands today is down to the three in combination; John Monaghan for starting his entrepreneurial ventures in the 70’s, HAF for their successful range of hardware in the 80’s and John Planck for the direction that took the company through to the 00’s.

One Combined Limited Company owned by the Family

The previously separate companies operate together whilst celebrating their individual heritage. We operate nationwide from our three sales offices – John Planck in Kent, John Monaghan in Yorkshire and HAF in Hertfordshire, with our distribution centre also in Yorkshire.
