FAQs
Are decking installers more expensive in the UK?
Labour rates can vary, but the biggest drivers are materials, access, and how much groundwork is needed.
Is composite decking worth the extra cost?
Composite can cost more upfront but often needs less maintenance. Compare lifetime costs and warranties.
Do I need planning permission for decking?
It depends on height, location and local rules. If the deck is raised or near boundaries, check guidance before building.
How long does a decking install take?
Small straightforward decks can take a few days. Larger or raised decks with extras take longer, especially with groundworks.
