Wood Pellet Buyer's Guide
Which Pellet Grade Does my Boiler Need?
Most domestic biomass boilers and stoves in the UK – including models from Fröling, Viessmann, Grant, and Windhager – require 6mm ENplus A1 wood pellets to maintain efficiency and protect warranty compliance.
As a general guide:
- Domestic pellet stoves: Usually require 6mm ENplus A1 pellets
- Domestic biomass boilers: Usually require 6mm ENplus A1 pellets
- Commercial biomass systems: May accept 6mm or 8mm, depending on the feed system design
- Industrial biomass boilers: Typically require 8mm pellets or specialist biomass fuels
Always check your appliance manual before ordering. Using non-certified pellets in systems designed for certified fuel can reduce efficiency, increase ash residue and may affect warranty cover.
What Are ENplus A1 Wood Pellets and Why Does Certification Matter?
ENplus A1 is the highest quality grade for wood pellets under the ENplus certification scheme, which is based on the international standard ISO 17225-2. Certified pellets are tested and traced from production to delivery, so you know the fuel meets a consistent standard every time.
To meet the ENplus A1 standard, wood pellets must have:
- Moisture content: 10% or less
- Ash content: 0.7% or less
- Energy content: at least 4.6 kWh per kg
- Durability: at least 98%, so they don't break down into dust in transit
- Diameter: 6mm or 8mm
Lower grades, A2 and B, allow higher ash content and are generally meant for larger commercial or industrial systems. For domestic boilers and stoves, A1 pellets burn more cleanly and efficiently, leave less ash, and reduce wear on the appliance. They're also the grade most manufacturers specify for warranty cover.

Your annual wood pellet usage depends on property size, insulation and heating demand. Most UK homes using biomass heating consume between 3–5 tonnes per year.
Typical usage guide:
- Small, well-insulated homes: 2–3 tonnes (130–200 bags)
- Average 3–4 bedroom homes: 4-6 tonnes (260–400 bags)
- Large properties or high heat demand: 6-10+ tonnes (400–670 bags)
How Should I Store Wood Pellets?
Wood pellets must remain dry to maintain performance. Exposure to moisture causes swelling, crumbling, and poor combustion.
- Store bags indoors where possible
- Use a waterproof cover
- Keep pellets off the ground
- Avoid damp or humid environments
- Keep bags sealed until use
