You would be lucky to find anyone qualified to service it and then it would probably cost more than you paid for the heater. You could ask in a caravan showroom as they sometimes service LPG equipment.
Look at the Calor website for a dealer / supplier near you.....
Some of the portable heater appliances have been subject to a recall since 2010 - a safety check is often free, so long as you buy your gas from them.

Some Calor Gas dealers offer Heater Health Check and Mobile Heater Servicing - go to www.calor.co.uk click on "find a stockist" enter your town or city and a list of stockists will appear, however do ring to make enquiries, before you make a long journey to get your heater serviced, Calor have a habit of denoting unlikely places as Mobile Heater Servicing agents such as filling stations, garages, plumbers merchants and camping shops etc.
