Smell coming from under floorboards - could boiler (leak) be potential cause?

In the last 2 weeks I've noticed a horrible smell coming through the floorboards of our home, the smell seems concentrated in the kitchen. We initially thought it could be a blocked toilet pipe, although the toilet itself isn't backed up, so called out a drains company. They could find any obvious issues after checking manholes, drains etc. Our house is raised approx 2 feet from the ground and he did lift a floorboard and the smell is definitely coming from under the house. After taking pictures, and without raising the whole floor at cost, he couldn't see any obvious issues. It was dry and debris free apart from usual builders rubble. This led him to think that perhaps a rodent has died under our house and this was the smell. I'm not convinced by this and wonder whether the boiler could be a potential cause. The water pressure is low under 1 bar and the boiler itself is a bit erratic - could this indicate a leak? Could the leak have led to damp floorboards that are not visible?
