Generally, verandas are considered Permitted Development for most properties and do not require planning permission if installed at the side or rear.  However it is important that you check whether Permitted Development (PD) rights exist for your property (for example, the do not exist for flats or maisonettes), and whether there are any specific restrictions where you live.  We DO NOT assess our designs for planning, so if you are in any doubt, you should consult your local authority BEFORE ordering your veranda.  Should you require drawings for this purpose, we are of course happy to provide them.
