Q: What types of garden decking do you sell?

A: We stock a range of timber decking and composite decking options, suitable for all kinds of garden projects. Whether you're building a full garden deck or refreshing an existing area, we’ve got the materials you’ll need. You’ll also find garden decking tiles and kits if you’re after a quicker or more modular solution.

Q: What are the most common decking materials?

A: Most garden decking is made from pressure-treated timber, which is durable, cost-effective, and easy to work with. We also offer composite decking boards if you’re after a lower-maintenance option. The choice of deck materials comes down to budget, maintenance preferences, and the look you’re after.

Q: What sizes does decking come in?

A: Standard decking sizes include lengths of 3.6m and 4.8m, with a width of around 120mm to 150mm, with other variants available depending on the board. This flexibility means that whether you’re building a small garden deck or something larger, you can find exactly what you need. Always check the specific sizes available on our product listings before ordering.

Q: How many decking boards will I need?

A: To work it out, start by measuring your deck area in square metres. Then check the width and coverage of your chosen boards. As a rule of thumb, allow for around 10% extra to cover cuts and waste.

Our decking calculator can help you calculate how much to order. If you're still not sure, visit your local JT Atkinson branch - we can help you figure out exactly what you need.

Q: How much is decking?

A: The cost of decking depends on the material, board size, and how much you need. Timber decking tends to be more affordable, with prices starting from £7.20 per board, such as our Arbordeck Smooth and Grooved Tanalised board. Composite decking is more expensive upfront, but requires less maintenance over time, which can save you money. You can also pick up garden decking kits at fixed prices for smaller builds.

Q: What’s the average garden decking cost for a full project?

A: For a basic timber deck, you could expect to pay between £300–£600 for materials, depending on the size of your decking and board choice. If you’re adding accessories like fixings, rails or steps, you should budget a bit more. Every job is different, so we recommend pricing it up based on your exact measurements and material choice.

Q: Are garden decking tiles a good alternative to traditional boards?

A: Yes, garden decking tiles are ideal for quick installations, small patios, or temporary solutions. Because they click together and sit on a flat surface, there’s no need for complex frameworks, making them a great solution for renters or anyone after a tidy upgrade with minimal fuss.

Q: Do I need planning permission for garden decking?

A: Most decking for gardens doesn’t require planning permission as long as it’s no more than 30cm above ground level and doesn’t cover more than 50% of your total garden area, including other outbuildings. If you’re unsure, check with your local council before you begin.
