Why more homeowners are choosing composite decking
Composite decking has become the premium alternative to traditional timber — and for good reason.
✔ Low maintenance
No sanding. No staining. No annual sealing. Composite boards retain their colour and finish with minimal upkeep.
✔ Long-term durability
High-performance composite boards resist rot, warping, splintering and insect damage — making them ideal for the UK climate.
✔ Modern, architectural finish
Clean lines, concealed fixings, and consistent board spacing create a sleek, contemporary aesthetic that enhances any garden.
✔ Slip resistance & safety
Many premium composite boards feature textured finishes designed to improve grip underfoot — ideal for families and entertaining areas.
✔ Sustainable materials
Brands like Millboard, Trex and NewTechWood use recycled materials and advanced manufacturing processes for environmentally responsible performance.
When installed correctly on a properly engineered subframe, composite decking offers decades of performance — not just a short-term garden upgrade.
Our design & installation process
A structured, professional approach from start to finish.
We follow a clear 4-stage process to ensure every project is engineered correctly:
1.
Initial consultation & budget alignment
Before we arrange a site visit, we take the time to understand your vision, layout, and expectations.
If you can provide approximate dimensions, we prepare a ballpark square metre cost estimate, helping you understand likely investment levels before progressing further.
This qualification step ensures:
-
Realistic budget alignment
-
No wasted site visits
-
Transparency from the outset
-
Efficient project planning

2.
Detailed site survey & structural assessment
Once viability is confirmed, we carry out a full technical survey of your garden in Merseyside or Cheshire.
We assess:
-
Ground levels and drainage
-
Subframe requirements
-
Access constraints
-
Structural support
-
Stair positioning
-
Balustrade compliance
-
Airflow clearance
This ensures your composite decking installation meets manufacturer guidelines and long-term performance standards.

Frequently asked questions about composite decking
1. How much does composite decking cost in Merseyside & Cheshire?
There are many variables that affect the cost of composite decking installation, but
as a general guide, our professionally designed, supplied and installed composite decking projects typically start from £250 per square metre.
Raised structures, multi-level layouts, integrated lighting, balustrades, or complex ground preparation will increase the overall investment.
If you can provide approximate dimensions, we can prepare a realistic ballpark estimate before arranging a site visit — ensuring budgets align from the outset.
2. Is composite decking low maintenance?
Yes — composite decking is significantly lower maintenance than traditional timber decking.
Unlike timber, composite boards do not require annual sanding, staining, sealing, or painting. They are engineered to resist rot, warping, splintering, and insect damage, making them far more stable in the UK climate.
That said, composite decking is not completely maintenance-free. Like any outdoor surface, it benefits from occasional cleaning to remove dirt, leaves, and debris. A simple wash with warm soapy water or a gentle pressure rinse a few times per year is typically sufficient.
For homeowners who want a long-lasting, attractive outdoor space without the ongoing upkeep of timber, composite decking offers a practical and reliable solution.
3. How long does composite decking last?
Most premium composite decking brands offer manufacturer warranties of 25 years. We also provide up to a 10-year installation guarantee on our workmanship, giving you long-term confidence in the structure and build quality.
4. Do I need planning permission for a deck?
In most domestic garden installations, planning permission is not required. However, raised decks above certain heights may fall under specific regulations. During our survey stage, we advise on compliance and any potential considerations.
5. Can you build decking on a sloped or uneven garden?
Yes. We specialise in raised and structurally engineered decking systems, including multi-level platforms and stepped garden layouts. Every project is CAD-designed before installation to ensure correct support and load distribution.
6. Is composite decking slippery when wet?
Premium composite decking is specifically designed to offer improved slip resistance compared to traditional timber.
The brands we install — including Millboard, Trex and NewTechWood — feature advanced textured or wood-grain surface finishes that help improve grip underfoot. These systems are manufactured with protective outer layers that are designed to resist moisture absorption and reduce the build-up of moss and algae.
That said, as with any outdoor surface, debris such as leaves or mud should be cleared periodically to maintain optimal performance. With basic routine maintenance, quality composite decking remains safe and practical for year-round use in the UK climate.
If safety is a particular concern — for example around steps or entertaining areas — we can advise on the most suitable board range and finish during your consultation.
7. How long does installation take?
Most standard composite decking installations take between 3–7 working days, depending on size and complexity. Larger structural or multi-level projects may take longer. We provide a clear timeline before work begins.
8. Do you remove existing decking?
Yes. We can remove and dispose of old timber or failing decking structures before installing your new composite system.
