There is huge local variation in fuel costs. Enter your own local data in the white cells.

This chart shows carbon emission as mass of elemental carbon, to convert emissions to CO2 equivalent multiply by 3.7
Wood, although considered carbon-neutral carries a small carbon overhead in the non-renewable energy required to process it.
Chart results represent energy costs only - costs of running, renewing, servicing and repairing equipment are not included.

This is based on data from a survey of fuel suppliers conducted in September 2009 and data from the UK Statistics Office at http://www.decc.gov.uk/en/content/cms/statistics/source/prices/prices.aspx with reference to the to 2009 Defra Conversion Factor Guidelines: http://www.defra.gov.uk/environment/business/reporting/pdf/20090717-guidelines-ghg-conversion-factors.pdf
