We will deliver to you either by Royal Mail, or by parcel carrier, according to weight and value of the order.

Certain items, such as long fluorescent tubes (3ft and above) can only be transported by courier due to the length and delicate nature of the product. Unfortunately as a small business we are unable to cover the costs for this.
