Decking Installer
A decking installer designs, builds, and maintains outdoor decking areas in timber and composite materials. From garden entertaining spaces and raised platforms to hot tub bases and balcony decking, they create functional outdoor living areas.
What does a decking installer do?
Decking installers handle the design and construction of outdoor decking, including:
- Composite decking supply and installation
- Timber decking construction (softwood and hardwood)
- Raised decking and multi-level platforms
- Decking with built-in lighting and power
- Balustrades, steps, and access ramps
- Hot tub bases and pergola integration
- Subframe design and ground preparation
- Deck maintenance, staining, and repair
Does decking need Building Regulations approval?
Decking under 300mm above ground level typically falls under Permitted Development and does not require planning permission, provided it does not cover more than 50% of the garden area. Raised decking over 300mm high may require planning permission and must comply with Building Regulations for structural safety and guarding.
Balustrades are required on platforms over 600mm above ground level. In conservation areas or for listed properties, additional planning restrictions apply. The structural subframe for raised decking should be designed to carry the intended loads safely.
What to look for when hiring a decking installer
When choosing a decking installer, consider:
- Material expertise — Composite and timber require different installation techniques. Ensure the installer is experienced with your chosen material.
- Subframe quality — The deck is only as good as its subframe. Ask about joist spacing, fixings, and ventilation beneath the deck.
- Drainage planning — The area beneath decking should allow water to drain away from the building. Poor drainage causes damp and structural issues.
- Anti-slip surface — Especially important in the UK climate. Ask about grooved boards or anti-slip inserts.
- Guarantee — Composite decking often has 25-year material warranties. Workmanship guarantees should be at least 5 years.
Frequently Asked Questions
How much does decking cost?
Timber softwood decking costs £25–£80 per square metre installed. Hardwood (such as Ipe or Balau) costs £80–£150 per square metre. Composite decking costs £125–£200 per square metre installed. A typical 15m² deck costs £1,500–£3,000 in timber or £2,500–£4,000 in composite, including subframe and fixings.
How long does decking last?
Pressure-treated softwood decking lasts 10–15 years with regular maintenance (annual cleaning and treatment). Hardwood decking lasts 25–40 years. Composite decking lasts 25–30+ years with minimal maintenance. Composite's higher upfront cost is offset by no painting, staining, or rot treatment over its lifetime.
