It is a fact that you can buy a light switch for as little as £2.50 and as much as £80 or more!
It is therefore ridiculous to price a project without defining clearly the materials being used.
With Datum, the products which you choose (or we propose) are defined in the Specifications which describe the products, their price and in many cases include a photograph. You can swap items, amend and respecify as you wish and you can rest assured that the materials we use on your project will be in accordance with the Specifications.
