Fire rated access to a gas meter under the stairs

[opps]

A customer has asked me to make a suitable access point to her gas meter which is currently under the stairs on the first floor of a 3 story building.

Her builders made a cover that simply pushes up against the staircase.



I am guessing that it need to be something fixed with doors. There is a spare FR door on site. I guess that I can cut it and lip the edges and use a spare length of FD door liner and then route an additional profile for the intumescent strip where the two door edges meet.

I would rather cover the frame with FR MDF rather than a double skin of plasterboard. My carpentry skill are sufficient, but I know little about fire regs/requirements.

Sensible advice is much appreciated.

Don’t think there are fire regs that apply , or half the UK are breaking them.

Common sense suggests that what ever you do does not inhibit rapid access to the Emergency Cut Off valve in the event of a gas leak.

The area is under stairs that lead up to the next floor/flat, and apparently need to have sufficient fire rating.
