What Do You Need? 

For simplicity, we’ll refer to your setup as a worm bin throughout this guide.

Materials required:

  • Worm Bin- Ready-made vermicompost system or upcycled DIY approach.
  • Earthworms- Eisenia fetida or Dendrobaena veneta.
  • Bedding- Creating a comfortable worm habitat, using shredded paper, cardboard, coco coir or aged compost.
  • Organic waste- Mainly food scraps like fruit and veg peelings, and coffee grounds.

💰 Vermicomposting Setup Costs

Starting a vermicomposting system doesn’t have to be expensive—but it helps to know where your money’s going. Whether you’re building your own bin from upcycled materials or investing in a ready-made wormery, setup costs can vary widely. This section breaks down the typical expenses for bins, bedding, worms, and optional extras, so you can choose a system that suits your budget and composting goals.

đŸȘ±

đŸȘ± Worm Bins

There’s a wide range of worm bin styles available in the UK, often referred to as wormeries or worm farms. Whether you’re after a compact indoor unit or a larger outdoor system, prices vary based on system type, size, materials, and included features.

Two Main Vermicompost System Types

When choosing a vermicompost system, you will typically come across two styles:

  • In-Ground Systems

These are smaller containers, buried directly into garden beds or soil. They are low-maintenance, blend into the background, and allow native worms to move between the bin and the surrounding soil.

  • Multiple Tray Systems

These sit above ground and use stackable trays to separate fresh waste from finished compost. Ideal for harvesting worm castings, managing food input, and scaling up over time. 

🛒 Worm Bin Costs: What to Expect

Your system costs mainly depend on: 

  • System Size
    Larger systems with multiple trays or greater capacity cost more. 
  • System Type
    • Ready-Made Systems: Prices vary by brand, style, and included features.
    • DIY approach: Often more affordable – especially if you can upcycle items meant for disposal.
đŸȘ±

Choosing the Right Size Worm Bin

The ideal size of your worm bin system depends on:

  1. Amount of Food Waste
  2. Available Space

1. Amount of Food Waste

To choose the right vermicomposting system, start by estimating how much food waste your household produces each week.

  • Average per person: ~200g per day
  • That’s roughly 1.35 kg per person per week

 

Our table uses these averages to estimate weekly food waste for different household sizes.

Figures are based on UK data from WRAP (2023) and WasteManaged UK (2024).

2. Available Space

Before picking your worm bin, consider where it will live. 

  • Indoor:
    • Ideal for compact systems (20-30 L).
    • Look for odour-control features and drainage taps.
    • Suitable places: under sinks, in utility rooms, or sheltered balconies.
  • Outdoor:
    • Ideal for larger systems (40-100 L).
    • Look for weather-resistance and elevation or drainage collectors.
    • Suitable places: gardens, sheds, or patios.
    • If you store your worm bin outdoors, it’s crucial to protect your worms from freezing temperatures.

In-Ground Systems

If you’re unsure about worm composting systems or only produce a small amount of food waste, an in-ground worm composter could be a simple, low-maintenance solution.

These systems are discretely buried directly in your garden soil, are odour-free, and allow native earthworms to come and go naturally—no need to purchase composting worms.

They’re ideal for raised beds, wildlife-friendly gardens, and anyone looking for a fuss-free way to recycle kitchen scraps and improve soil health.

Interested in an in-ground vermicompost system?

You’ve got two great options:

  • Buy a purpose-built system – These are designed for easy installation and minimal maintenance.
  • Try a DIY approach – If you have lidded buckets or PVC pipe, you can drill ventilation and access holes and repurpose them into simple, effective worm composters.

🛒 Purpose-Built In-Ground Systems

A range of in-ground worm composters are available in different sizes, ready to be placed directly into your garden beds. These systems offer a simple, low-maintenance way to recycle kitchen scraps and enrich your soil—no trays, no fuss. Costs range from £7 to £45, depending on the size and capacity of the system.

Recommended Options

Below is a list of options you may wish to explore.

Tumbleweed Worm Buffet ~ ÂŁ 40

DIY Approach In-Ground Systems: 

Using lidded buckets:

  • Repurpose a bucket with a secure lid.
  • Drill (ÂŒ inch/6 mm) holes in the sides and base for airflow and worm access.
  • Optional: Add some holes near the top of the bucket sides for additional ventilation.
  • Bury the bucket halfway into garden soil. 
  • Add food scraps and bedding materials.
  • Keep the lid on to deter pests and retain moisture.

DIY Approach In-Ground Systems:

Using PVC Pipe (10-15 cm diameter, ~30-50 cm long):

  • Drill (ÂŒ inch/6 mm) holes around lower half of the pipe for airflow and worm access.
  • Bury the pipe vertically in garden soil, leaving the top exposed.
  • Add food scraps and bedding materials. 
  • Cover with lid or flat stone to keep pests our and moisture in.  
PVC Safety
✅ When PVC Is Acceptable
  • For in-ground systems, PVC is generally considered safe because it doesn’t come into direct contact with food or worms long-term—just bedding and scraps inside the pipe.
  • Rigid, uncoated PVC is preferable. Avoid flexible PVC or pipes with chemical coatings or treatments.
  • Use food-safe or potable-grade PVC if available (often labelled for water supply use).

⚠ Things to Watch Out For

‱ Drilling safety: Sand edges after drilling to avoid sharp fragments.
‱ End-of-life disposal: PVC isn’t biodegradable, so consider longevity and reuse options.

♻ Alternatives to PVC for In-Ground Worm Systems

If you’re looking for low-impact or natural materials, these alternatives offer worm-safe, breathable options—ideal for eco-conscious setups or school-friendly projects.

  • đŸș Terracotta Chimney Pots or Clay Drainage Pipes
    • Pros: Breathable, durable, naturally regulates moisture
    • Cons: Heavier, may crack in frost-prone areas
    • Best for: Permanent installations in gardens or raised beds
  • đŸŒČ Untreated Wooden Tubes or Posts (Lined with Fabric)
    • Pros: Natural, compostable, blends into garden aesthetics
    • Cons: Prone to rot over time unless elevated or lined
    • Best for: Short- to medium-term use in well-drained soil
  • 📩 Heavy-Duty Cardboard Tubes
    • Pros: Compostable, easy to source, great for seasonal systems
    • Cons: Breaks down quickly, not suitable for wet or compacted soil
    • Best for: Temporary feeding stations or school garden projects

Why Choose a Multi-Tray System? If you’re new to vermicomposting or looking to scale up, multi-tray wormeries offer a smart solution. These stackable bins allow worms to move between layers as they finish processing food, making it easier to collect castings without disturbing your colony. They’re ideal for households that want a tidy, modular setup with minimal mess.
