what SHOULD a gas safety check (CP12 etc) consist of (as a minimum, say for eg a r/s boiler:
tightness test of installation (let-by test before of ecv)
inspection of gas pipework
ecv accessible/satisfactory
equi bonding check
visual check on flue - route/termination etc (ventilation if required)
checking of operating/burner pressure / gas rate
flue gas analysis (coc / co2 ratio check)
boiler case seals check - if removed
i presonally always check condesate / prv route/termination (if applicable)
earth continuity check/fuse check (3 amp)
co room level check
co2 % if a-rated/premix burner (check/adjust if necessary)
co alarm fitted/tested / advised to fit
check pressure on gauge is satiosfactory (if applicable)
do some companies check more/less?
