Always calculate your internal floor size when ordering a conservatory. Most conservatory companies will quote you for the external area, but it's the internal floor area most people are interested in.
Get about three quotations but don't go for the cheapest quotation. The cheapest supplier will rarely give you the best product or service.
Depending on the shape of the conservatory, it is generally not advised to put doors in the front of the conservatory, as it creates a corridor, which will make it difficult for you to arrange the furniture.
Lead your conservatory off a room that you use much, like your kitchen or living room.
Don't compromise on the size of your conservatory.
Don't let the shape of your house be disturbed by your conservatory.
Decide on a conservatory shape that will enhance the outlook of your home.
Try to match the construction materials of your conservatory with the ones used for your home.
Try to match the colour of your conservatory with the colours used for your home.
Take interesting details like bargeboards and unusually shaped windows into the design of your conservatory.
Have a plan drawn up by an architect if you are looking for a specific design that is a bit out of the ordinary. This way you will know what to talk about with the supplier and he will not try and sell you his designs as much. On top of that, you will be able to compare on a like for like basis, which is very important when you get more than one quote.
The more money you spend on the right insulation and roofing and glazing systems, the less you'll end up spending on heating and cooling systems for your conservatory.
While making a plan, add sufficient funding for extras such as blinds, furniture and heating.
