Who are we?

MultipurposeCompost.co.uk is an independent information platform created to help gardeners, landscapers, and compost buyers make sense of the UK compost market.

We have no brand affiliation or sales agenda — our goal is clarity. We review, test, and interpret compost information objectively, using science-based analysis and clear consumer language.

Why do we exist?

MultipurposeCompost.co.uk was created because the UK gardening market lacks a neutral, data-driven source of compost advice. Many “reviews” online are brand-sponsored, incomplete, or outdated. Our mission is to bring clarity and trust back to one of gardening’s most confusing categories.

We focus on:

• Explaining what’s actually in the bag.
• Helping consumers choose the right compost for their plants.
• Highlighting where sustainability claims and performance data deserve scrutiny.
• Encouraging compost brands to publish clear specifications and lab results.

Every guide and FAQ on this site is written with that neutrality in mind.

Our Ecosystem.

Compost is the beginning of soil health — not the end. Our content links outward to HealthySoil.uk, where the science of humus formation, microbial life, and carbon stability is explored in more depth.

Together, these sites form a connected knowledge ecosystem:

• MultipurposeCompost.co.uk – practical consumer guidance.
• Healthy Soil – how soil works, insights.
• Biochar Filters – what, where and how to use them.
• Biochar Humus Composite – a new class of soil improvers.

This structure helps both gardeners and search engines follow a clear, transparent pathway from “what’s in the bag” to “what happens in the soil.”
