Delivery included

Delivery to mainland England and Wales is included in all of our package prices. It's also included in selected areas of Scotland but you need to check with our staff as we occasionally have to make extra arrangements for areas above the central belt which may cost a little extra.

On delivery the greenhouse and staging are contained in the larger cardboard boxes, the accessory items are grouped together and the glass needs a clear length of wall to lean against, preferably in a garage or outbuilding. In this instance it is safely stacked against a sheltered garden wall. Nothing in the boxes will take any harm if it gets wet during storage, with the possible exception of the instructions; after all, the greenhouse is intended to stand outside in all weather !

You will be advised of the delivery date so you can ensure that the delivery driver can gain access to unload the boxes and glass.

D.I.Y ?

Should you choose to install your greenhouse yourself this is what you will find when you unpack the boxes ! The components here are from our smallest greenhouse ( 4ft x 4ft ) but the principle is the same with all sizes. Aluminium components are carefully wrapped and labelled to tell you which section they belong to. All you need to do is follow the instructions on preparing them and assembling them which are also provided. ( Orange booklet in this picture ). All clips, nuts and bolts and rubber glazing beads are provided in the pack too. Glass is delivered at the same time as the greenhouse and stacked where you request.

If you prefer to have your greenhouse installed then please talk to a member of our staff who will be happy to explain the various fitting options available to you.

5 inch Aluminium base plinth

This base plinth is provided to add strength at ground level and to make installation of the greenhouse easier. It replaces the need to lay foundations and a brick plinth in most situations.

With longer versions of our Supreme and Classique Greenhouses ( above 16ft ) we will not provide an aluminium plinth unless they are purchased with a partition.

If you choose a coloured framed greenhouse we can provide the base in the appropriate colour to match the framework.
