"Any weird smells could indicate incomplete combustion and spillage of flue products. I would advise turning off the appliance and any other carbon fuel appliances in the property and contact the emergency service provider on 0800 111 999.
Good luck and stay safe!!"

"An eggy or sulfuric smell emanating from the boiler cupboard could indicate a potential gas leak. It's crucial to address this immediately as gas leaks can be dangerous. Here are steps to ensure safety:

Ventilate the Area: Open windows and doors to allow fresh air in. Avoid using anything that could create a spark or flame, including light switches.

Turn Off the Gas: If it's safe to do so, turn off the gas supply to the boiler. The gas shut-off valve is typically located near the meter.

Leave the House: Evacuate the premises and ensure everyone's safety. Do not turn on or off any electrical switches or devices while in the house.

Contact the Gas Company or Emergency Services: Report the smell of gas immediately. Gas companies often have emergency lines to deal with such situations promptly.

Do Not Ignite Anything: Avoid using matches, lighters, or any electrical devices until the area is deemed safe by professionals.

Gas leaks are serious safety hazards and require immediate attention. Even if the smell dissipates or seems minor, it's better to err on the side of caution and have professionals inspect the area. Your heating and hot water might be affected temporarily, but your safety is the priority in this situation."
