Timber hardwood and composite decking are the most popular choices in London. Composite is gaining popularity for its low maintenance, while hardwood remains the premium choice for natural appearance and longevity. Treated pine is the most affordable option for budget-conscious projects.

Pergola costs in London start from £260/m² for an open timber structure and range up to £750/m² for a fully insulated patio roof. Prices include VAT. Planning permission required if structure is over 2.5m high. Permitted development rules apply in most cases.
