hello,,,i recently moved into a different house,,,ive been there less than a month,,,after a couple of weeks i started getting chest pains and sore throats,,,also my jack russel who had been in perfect health before we moved in started having seizures and breathing dificulties,,,ive had to send the dog to my relatives and shes been fine since getting away from this house,,,ive turned the boiler off and not used it since,,,it is an oil burning boiler situated in the cellar,,,i read it could be either carbon monoxide or nitrogen dioxide,,,do i just get a gas engineer out to test for this or is it someone else i should be getting out to test etc??? i cant seem to find any info on who does the tests etc so would appreciate any advice off any of you gas lads,,,cheers............
