I have no doubt these are Habitat kitchen units, dating from a time when self assembly kitchens were largely in their infancy. At some point knobs have been added that were not originally intended - this was meant as a low cost, basic but stylish kitchen. With a bit more TLC it could be almost back to its original 1970s loveliness
Don't know a great deal about these, they were merged into the Radiation Group along with Jackson & Parnall but seem to have disappeared around the mid 1960s.
Doing these threads I have frequently posted Tricity President models, this was pretty much the last of the line in the late 1980s - fan oven and one halogen burner - the pinnacle of 1980s technology LOLOL Personally I much prefer the styling of the 1970s models
Now this is something I have never seen before, an electric kettle with a bain marie insert. And a dual capacity element - again never seen that before. If the element does not work I cannot conceive of getting an exact replacement
These are quite rare. I would date this as pre 1973 as my mother bought a Sunbeam iron that year with the much wider heel rest - that was a "Shot of Steam" and I would buy one in a heartbeat if I could find one
