In short: Practical guide to switching to peat-free in the UK in 2026. Major UK retailers — B&Q (since 2023), Royal Botanic Gardens Kew (end-2025), the RHS (January 2026), and Verve (January 2026) — have moved to peat-free formats voluntarily. There is no statutory UK peat ban; a Horticultural Peat Bill is before Parliament but not yet law.
Peat-Free Gardening UK 2026: The Complete Transition Guide
Peat has been a staple of UK horticulture for decades. But its days are numbered. The UK government has committed to phasing out peat use in amateur horticulture, and many of the UK's largest retailers have already moved to peat-free ranges. If you are still using peat-based compost, now is the time to understand your options and make the switch confidently.
Why Are UK Retailers Moving Away from Peat?
Peat bogs are ancient, carbon-rich ecosystems that took thousands of years to form. The UK and Ireland's peatlands store approximately 3.2 billion tonnes of carbon — more per hectare than tropical rainforests. When peat is extracted, that stored carbon is released as CO₂.
Key facts:
- UK peat bogs cover approximately 3 million hectares but only 20% remain in good condition
- Peat forms at a rate of approximately 1 mm per year — making extraction effectively irreversible
- The UK horticultural industry used approximately 700,000 cubic metres of peat annually before restrictions began
- Intact peatlands also support rare wildlife, filter water, and regulate flooding
UK Peat-Free Timeline: Retailers, Institutions, and Legislation
| Date | Milestone |
|---|---|
| 2020 | UK Government consultation: phase out peat for amateur retail use |
| 2023 | B&Q goes peat-free for own-brand growing media |
| End 2025 | Royal Botanic Gardens Kew goes peat-free across all garden operations |
| January 2026 | RHS gardens go peat-free for amateur growing media; Verve (B&Q in-house brand) is peat-free |
| February 2026 | Horticultural Peat (Prohibition of Sale) Bill introduced in Parliament — private members' bill, not yet enacted; no statutory ban currently in force |
What UK retailers and institutions say
- B&Q: own-brand garden compost peat-free since 2023; in-house Verve range peat-free from January 2026 (B&Q)
- Royal Botanic Gardens, Kew: peat-free across all garden operations from end of 2025 (Kew Gardens)
- Royal Horticultural Society (RHS): RHS gardens peat-free for amateur growing media from January 2026 (RHS)
These voluntary moves are the practical reality for UK gardeners. There is no statutory UK peat ban currently in force — a Horticultural Peat (Prohibition of Sale) Bill was introduced in Parliament in February 2026 as a private members' bill, but is not yet law.

What Are the Best Peat-Free Alternatives?
| Alternative | Best For | Key Benefit | Limitation |
|---|---|---|---|
| Coco Coir (buffered) | Containers, greenhouse, seed starting, hydroponics | Excellent water retention and aeration; stable pH; reusable | Low nutrients — requires feeding programme |
| Peat-free compost | General gardening, raised beds, soil improvement | Nutrients included; improves soil biology | Quality varies between brands; can compact |
| Wood fibre | General potting, seed starting | Good structure; renewable | Consumes nitrogen during breakdown; dries out fast |
| Green compost | Soil amendment, mulching | High organic matter; improves soil fertility | Variable quality and consistency |
| Biochar | Soil amendment as an additive | Long-term carbon storage; improves nutrient retention | Expensive; not a standalone growing medium |
Why Coco Coir Is the Best Peat Replacement for Most UK Growers
Of all the peat-free alternatives, buffered coco coir most closely replicates the properties that made peat so popular:
- High water retention — holds moisture as well as or better than peat
- Good aeration — does not compact like peat can when wet
- Stable pH — 5.5–6.5, compared to peat's acidic 3.5–4.5
- Lightweight and consistent — compressed bricks expand to a predictable volume
- Reusable — 2–3 growing cycles vs peat's single use
How to Make the Switch to Peat-Free
- Identify where you currently use peat: Potting compost, seed compost, hanging baskets, grow bags.
- Replace like for like: Use coco coir or peat-free compost in the same applications. Start with one application type to build confidence.
- Adjust your watering: Coco Coir retains moisture well but does not compact. It can look dry on the surface while being moist underneath. Water less frequently and check by feel.
- Start a feeding programme: Unlike peat compost mixes, pure coco coir has no nutrients. Use a balanced liquid feed from week 2 onwards.
- Monitor results: Most growers report equal or better results with coco coir after 1–2 seasons of adjustment.
Common Concerns — Answered
"Peat-free compost hasn't worked well for me in the past."
Peat-free composts vary enormously in quality. Many early formulations used wood fibre that broke down quickly and became hydrophobic. Coco Coir does not have these problems — it is structurally stable and re-wettable. If past peat-free experiences disappointed you, try buffered coco coir as your base medium.
"I grow specialist plants that need peat."
Acid-loving plants (blueberries, heathers, rhododendrons) that traditionally used peat can be grown in a mix of coco coir with added sulphur to lower pH. Orchids do well in bark-based mixes with 20–30% coco coir.
"Will my plants be OK during the transition?"
Yes, provided you adjust watering frequency slightly and implement a liquid feeding programme. The transition is straightforward for most plants.
