Replacing a MK1 gas meter box with the MK2 gas meter box:

This depends. If the MK1 front is damaged and needs replacing, we recommend that you take off the MK1 front and check the gas back. If the gas back is not damaged you do not need to remove it from the wall and can simply use our replacement gas cover for the MK1 to fix your damaged gas box.

However, if the back is damaged, you can buy the replacement MK2 surface gas meter box for a full replacement.
