How Much Does Garden Decking Cost in 2026?

It’s one of the first questions homeowners ask when planning an outdoor upgrade. At Bespoke Chester, we design and install high-quality decking across the UK, helping homeowners invest wisely in outdoor spaces that last.

Decking prices in 2026 vary depending on materials, garden size, groundwork, and installation quality. On average, homeowners can expect to spend between £1,800 and £6,000+ for a professionally installed deck, with premium designs exceeding this range.

Let’s break down the costs clearly without jargon, confusion, or hidden surprises.

Average Garden Decking Costs in the UK (2026)

Here’s a realistic breakdown based on current UK market rates:

Small deck (10–15m²): £1,800 – £3,000

Medium deck (15–30m²): £3,000 – £5,000

Large deck (30m²+): £5,000 – £8,000+

These prices include materials, labour, fixings, and professional installation.

What Affects the Cost of Garden Decking?

Several factors influence your final price:

1. Decking Material

Timber decking costs:

Softwood: £40 – £80 per m² installed

Hardwood: £80 – £140 per m² installed

Composite decking costs:

£100 – £180 per m² installed

Composite decking costs more upfront but lasts longer and requires less maintenance.

2. Garden Size and Layout

Larger gardens require more materials

Sloped or uneven ground increases groundwork costs

Multi-level designs raise structural complexity

Every project is priced based on your garden’s unique layout.

3. Ground Preparation and Foundations

Groundwork often makes up 20–30% of total decking cost.

This includes:

Ground levelling

Weed membranes

Concrete footings

Drainage adjustments

Solid foundations are essential for long-term durability.

4. Design Features and Extras

Additional features increase overall cost:

Steps and balustrades

Integrated seating

Lighting systems

Privacy screens

These features enhance usability and visual appeal while adding value to your home.
