Supporting our community

At KIS we pride ourselves on the importance of supporting local charities and institutions. To this end we make regular donations and attend many fund raising events. Below are some examples of recent events.

Dave Cole cancer fund raising golf day

In January 2011 the the managing director of one of our oldest and closest customers sadly died of cancer. After this sad loss the new managing director of the company Mark Cole (Dave's Son) decided to hold a fund raising day in memorial of a proud man and to try and raise some much needed money to support sufferers of the same tragic illness.

Due to the long and close relationship between our two companies KIS were very proud to be a part of this special event.

Many golf balls will never be found again and our very own sales director managed to break his favorite golf club in half to the amusement of the rest of the team.

Most importantly we raised a glass to Dave and the day raised a large amount of money for charity. Many thanks to Mark and all of the staff at ETS for organising a great day.

Brislington under 7's Football Team

Brislington Juniors is a local team with some very promising players. After talking to Matthew Muscatt, one of the coaches we realised that financial support for the local charity teams is very sparse.

The under 7 team were very pleased to receive their new training kit donated by KIS and hopefully will help them keep warm during their cold training sessions.

The Lighthouse Club

The Lighthouse club is an annual fund raiser established to help support people in the construction industry that have fallen on hard times. KIS have attended this event 3 years running and often donate prizes to be auctioned off by comedian Stan Boardman. Support for the day is very high and KIS are proud to be part of it.
