Combi boiler advice - pressure keeps going down

Hi guys.

Quick one - the pressure on my boiler keeps going down - I presume it's a sealed system. I put more water in quite regurally so the water must be going somehwere.

Does this definately mean a leak? Nothing is coming through the ceiling so if the pipes are leaking it must be under the floor on the ground floor - if this is the case then I'd imagine that finding it would be a major job!

I know nothing about boilers but I'm hoping a sealed system has some kind of saftey outlet - perhaps this outlet is slightly open? If this is the case, where would the water go? There's no overflow pipe on the outside of my house.

Thanks in advance for any comments
