You can choose to ignore the relevant legal paperwork, but you need to be aware that unless you have the certificate from the gas supplier/s then, if any accidents occur, then your household insurances (both structural and contents) and most importantly, your public liability (should you have someone renting your apartment) will be null and void!
You may choose to ignore this but, if you are n an apartment or urbanisation that has adjoining properties to your residence, you have to take into consideration your liability!
Better to be safe than sorry,
