Wood Pellets Supplier UK
The UK has one of Europe's more developed markets for wood-pellet heat, and sourcing it from Spain means a customs declaration — but not necessarily the ISPM 15 paperwork you might expect.
The UK has one of Europe's more developed markets for biomass heat — pellet stoves and boilers in off-gas-grid homes, farm buildings switched over from oil, and commercial biomass installations that built up momentum over the past decade or so. All of that runs on a supply of wood pellets, and Maderas Caamaño supplies pellets from its sawmill in Vimianzo, Galicia, to buyers across Europe. Since the UK left the EU, it sits outside the single market and customs union, which means a customs export declaration applies to any shipment — a genuinely different position from an EU destination.
This page is about the pellets themselves and the UK heating demand they serve, not a general export-logistics rundown.

A mature market for wood-pellet heat
Wood pellet heating in the UK spans several distinct groups of buyer: homeowners off the mains gas grid running pellet stoves and boilers instead of oil, farms and rural estates with biomass installations, and commercial or light-industrial sites running larger boiler plant. The UK's Renewable Heat Incentive scheme helped build out a good share of that installed biomass capacity over the past decade, and although the scheme has since closed to new applicants, the boilers and stoves it helped install are still burning pellets every winter. That's a market with real, ongoing pellet demand, and it's one Maderas Caamaño is positioning to supply into as an additional source, alongside whatever a UK buyer already sources domestically or from established European producers.
That installed base also means demand doesn't disappear once a scheme closes — a boiler bought under a support programme still needs fuel for as long as it's in service, often for many years after the incentive that paid for it has ended. For a distributor or fuel merchant, that translates into a steady replacement market rather than a one-off installation boom, which is exactly the kind of demand a supplier can plan production and shipping around, rather than chasing a single seasonal spike.
What changes for a non-EU pellet order
Being outside the EU customs union means a customs export declaration is required for shipments to the UK, unlike the checkpoint-free trade that applies within the EU. It's worth being precise about what that does and doesn't affect for a pellet order specifically: the pellets themselves, and the bags they're packed in, aren't subject to ISPM 15 heat-treatment marking — that requirement applies to solid wood packaging material, meaning pallets, crates and dunnage, not to the pellets or the sacks that hold them. Where ISPM 15 does become relevant is if bagged or bulk-bagged pellets travel to the UK stacked on solid wood pallets, since those pallets, as wood packaging leaving the EU, do need to be heat-treated and marked. It's a distinction that's easy to miss when sourcing from outside the UK for the first time: the fuel isn't the ISPM 15 concern, the pallet underneath it can be.
Format and specification for UK buyers
Pellets are produced at 6mm or 8mm diameter, moisture below 10%, ash content under 0.7%, with a calorific value in the region of 4.6-5.3 kWh/kg — manufacturing parameters aligned with the ENplus reference framework, not presented here as a certification claim. Supply is available loose in bulk, in palletised 15kg bags, or in bulk bags, and the choice of format is worth thinking about alongside the ISPM 15 point above: a bulk tanker delivery avoids the wood-pallet question entirely, while a bagged or bulk-bag order on pallets means factoring heat-treated, marked pallets into that particular shipment. Full specification and packaging options are on the wood pellets product page.
Sourcing pellets from outside the UK
For a UK buyer used to sourcing pellets domestically or from established Northern European producers, a Galician supplier is a genuinely different profile — a Southern European mill with its own timber base, offering an additional line of supply rather than a replacement for what's already working. That's a useful position for a distributor who wants to avoid depending on a single producer through a busy winter, or who wants pricing leverage from having more than one active quote on the table when volumes are being planned.
Maderas Caamaño doesn't have an existing track record of shipments into the UK to point to, and we'd rather say that plainly than imply otherwise. What we can offer is straightforward: manufacturing parameters aligned with the ENplus framework, the packaging format that suits your operation, and export documentation — customs declaration and, where pallets are involved, ISPM 15 treatment and marking — handled as standard. Get in touch with your volume and format and we'll talk through whether it's a fit.
Frequently asked questions
Does ISPM 15 apply to wood pellet shipments to the UK?
Not to the pellets or the bags themselves — ISPM 15 heat-treatment marking applies to solid wood packaging material, meaning pallets, crates and dunnage, not the fuel or its sacks. If a bagged or bulk-bag order travels on solid wood pallets, though, those pallets do need to be heat-treated and marked, since the UK is a non-EU destination.
Do we need a customs export declaration for UK shipments?
Yes. The UK sits outside the EU customs union, so a customs export declaration is required for any shipment from Spain, unlike the checkpoint-free trade used within the EU. This is handled as a standard part of preparing a UK order.
How long does a pellet delivery to the UK take?
Transit for the UK depends on the crossing and customs processing involved, so we don't quote a fixed number of days here. Contact us with your delivery point and volume and we'll talk through timing for your specific order.
Is there a minimum order for pellets to the UK?
Pellets to the UK are typically supplied by the full truckload, in line with standard road-freight economics. Contact us with your target volume and format and we'll confirm what's workable for your order.
