About iTip® ....

This is grassroots innovation at its best, from working in the garden, a small acorn grew into a revolutionary idea. This idea came from a real requirement to help gardeners and builders alike, in their day to day stresses and strains. Quality and cost were always a consideration and this has led to a product that is being covetted by the UK’s as well as the US’s largest DIY retailers.


At Allder's we always strive to leave an impression with our customers that they will want to work with us again and again. Therefore we take our customer feedback very seriously. It is always analysed to make sure we are providing the best service and product possible. We aim to gain maximum scores on all feedback tidiness, timekeeping, courtesy and workmanship.

Don’t just take our word for it, please read the reviews and check our feedback across the internet.
