Combi v standard boiler

Hi I am in process of doing down stairs of my house and currently have 15mm gas pipe, (I don't need a new boiler yet but was thinking for future) is it worth up grading to 22mm pipe as then I have option of combi boiler without ruining my floor if I ever upgrade

    Gas flow can be sufficient with 15mm. If you can do the job without disruption now it could be worthwhile.
    This is an open forum, anyone can post and I just did !

    It's very very unlikely 15mm would be enough for a combi. Best of changing it if you think you might change to a combi in the future.
