The New Web Site!

Welcome to our new web site. I hope that you will find it easier to use than our old one. One of the improvements is our ability to add product permits and brochures. Keep an eye out for these in the near future.

Another improvement is a list of featured products on our home page. This shows a selection of products that may be of use to you during this time of year.

Many of the enqiries we get are from customers asking where to purchase our home garden range from. we have now added a page with the details of our home garden distributors so you can ask them the name of your nearest retailer stratight away.

I hope you find the Colin Campbell (Chemicals) site to be very useful, please feel free to provide us with any suggestions via the form on our contact page. We appreciate any feedback.
