Some two million homes across the UK are not connected to mains gas, and 150,000 use LPG to providing heating.
AvantiGas - Chesterfield’s most profitable company - supplies liquefied petroleum gas across the UK via 15 distribution centres.
LPG is cleaner and greener than oil or coal.
It made £11.2m last year, up from £9.4m the year previous which itself was a near six-fold increase on the year before.
It had climbed from 19th to 17th on the Top 100 table last year, but dropped to 25th this year after turnover fell from £193m to £178m.
AvantiGas is part of the UGI group, a US-based global distributor and marketer of energy products including propane, butane and natural gas.
It was launched in 2011 and operates as a bulk provider of LPG to homes, businesses and for fuelling vehicles the UK.
United Kenning Rental maintained its £10m pre-tax profits after last year. Then, it was enough to top the table. This time it was pipped into second place.
The company, part of Germany’s largest car rental firm, Sixt, made £5.8m profit in 2013 and £7.5m in 2012.
Mallinckrodt Medical Holdings (UK) of Staveley was third again - and stayed in 47th place on the main table too.
But profits were up £1m, from £2.8m to £3.8m this time. Turnover rose from £79.6 to £89.7m. The firm was part of pharmaceutical, chemical, imaging and respiratory equipment business Covidien Holdings until it spun off the pharmaceuticals business as a standalone company two years ago.
Motor dealer Huntson Holdings Plc is 9th for profit in Chesterfield, with £1.3m, up from £734,000 the year previous.
Staff numbers have held steady at 220 but turnover has risen over the last two years to £71.3m.
