Wood fuel quality is at the heart of everything we do at MWF and is crucial to the effective and efficient operation of your wood fuel boiler.
Woodsure – Wood Fuel Quality Assurance Scheme
We are accredited by Woodsure the industry’s leading wood fuel quality assurance scheme. Woodsure certified woodfuel is an assurance to customers that the fuel you are purchasing fulfils the appropriate specification for your equipment and that the supplier has procedures in place to check that the fuel is consistently manufactured to these standards. It helps to guarantee a high standard and reliability in the supply chain.
Woodsure’s stringent quality evaluation regime encompasses every part of our business including timber sourcing, storage, production, distribution and customer relationships.
All our production processes are in accordance with BS EN ISO 17225:2014 (Solid Biofuels – Fuel specifications and classes).

Wood fuel Energy Ratings
All our wood chip is sold as energy in £/MWh rather than in £/tonne or £/m3. Click to watch the 1 minute video.
Many wood fuel suppliers invoice based upon the weight of the chip delivered however this is not necessarily an accurate measure of the materials’ worth as the weight varies with moisture content. To be completely transparent, and fair to our customers, we accurately measure the actual moisture content and exact weight to calculate the true energy value and invoice this in £/MWh rather than in £/tonne.
Wood fuel quality benefits:
- You pay for the actual energy you get without potential variation in moisture content affecting this;
- You pay for energy in the same way as gas or electricity so it is easier to compare;
- This provides an inbuilt quality control process for you as the customer;
- You can accurately analyse the energy supplied in MWh with the heat produced by your boiler in MWh to calculate your boilers efficiency. For example if we supply 100 MWh and your heat meter shows that this produces 80MWh of heat, then your boiler is operating at 80% efficiency. This then allows you to alter the way you operate your boiler to give you the best efficiency possible for your installation and we can advise you on the best ways to do this.
It takes approximately nine to twelve months for green timber to naturally season to around 30% which is required for most boilers.
In 2013 we invested in a new computerised Stock Management System to ensure that the timber we purchase matches our sales volume commitment in the future. This means that we will always have sufficient fuel at the correct specification to match your requirements. As part of this process we offer twelve month, fixed price rolling contracts to give you complete confidence that your fuel will be available at the price agreed throughout the coldest winter.
We recently invested in a purpose designed Jenz HEM56 wood chipper to ensure that all our wood chip is produced to the fuel size that our customers require.
