There are two main legal factors to think about in choosing a conservatory: Planning Consent and Building Regulations. Most conservatories need no Planning Consent at all but the rules governing this are many and complex. They also vary between England & Wales, Scotland, Northern Ireland and the Republic of Ireland and in some cases they may even vary from one local authority to another.
Again, Building Regulations can be complex. They are the rules that govern things like safety and stability of any building.
In either case, don't worry; your Network VEKA member can advise on all such matters and can even help you with the formalities.
