That’s very helpful, thank you. From that reading, it would seem that even built in ovens which are plugged in rather than hard wired are liable. Some of our built in ovens are plug in, it just depends on the rating of the individual oven as we have a variety of makes. Similarly, gas fired hobs which have plug in mains ignition would also seem to be liable. Thatā€™s a lot of testing over 32 almshouses!
