You won’t usually need planning permission for an LPG storage tank as long as it is no bigger than 3,500 litres, no higher than 3 metres, or 2.5 metres and if it is within 2 metres of a boundary. A good and professional boiler business like Total Boiler Services have the expertise to advise you on all of this and will design your LPG boiler system around your property and your business needs.
