After a string of acquisitions, revenues jumped to £19.7mln (£1.3mln), while the AIM-listed group also posted a profit of £930,000 (£7.7mln loss).
Richard Burrell, chief executive, said acquisitions over the past year had driven the improvement and will give sales a further kicker in the current year.
"The acquisition of three fuels businesses, which will see further turnover growth next year reflecting a full year's trading, has made for a transformational year at AMP.”
AMP also today announced the acquisition of a 50.1% stake in Highland Wood Energy, a Scotland-based wood chip supplier that will become part of its Forest Fuels operation.
Most of the profits this time came from the boiler installation scheme financed by its projects business, which chipped in £1.64mln, while wood fuels contributed £367,000.
Assets under management gew to £66m comprising operational boilers, in-development peaking plant assets and other biomass assets on long term contracts.
"AMP has a growing pipeline of new project developments which should continue to generate upfront development fees as well as deferred development fees in subsequent years and hence we look forward to the future with confidence."
