OK so plinths are not totally essential for Aga range cookers but most do have them to raise the surface of the hob level with the worktops. Later models like 'TC', 'DC' and 'City' cookers have them built in so do check!
'Standard' and 'Deluxe' cookers are 851mm high to hob/hotplate top. Subtract these measurements from the height of your worktop to establish the plinth height required.
Width wise the plinth should be the same as the base of the cooker. All 2 oven models are 987mm wide and 4 oven models 1487mm wide.
For plinth depth 'Standard' and 'Deluxe cookers require 679mm from the back wall. If you plan on tiling the front of the plinth then reduce these measurements by the thickness of the tiles you have chosen.
If your existing floor is sufficiently strong and non-combustible (like a concrete screed for example) then it is much easier to use our ready made plinths. These can raise the cooker 50-65mm. Much easier than getting a concrete plinth perfect! Our plinths are suitable for gas, oil and 13amp electric Aga range cookers. They are not suitable for 30amp 'night storage' cookers.
