How do I connect it?
All Hotpoint built-in electric single ovens can be fitted with a 3-pin plug, even those with catalytic stay-clean liners. That's pretty handy if you don't want to call out an electrician. Any gas single ovens need to be installed by a gas safe fitter. When it comes to double ovens, they'll need to be installed by a qualified electrician or gas safe fitter.
Where can it go?
Single ovens can either be fitted under your worktop or built into a housing unit. Most double ovens are designed to slot into a tall housing unit but you can buy some built-under that are slightly smaller to fit under your worktop. You'll get a similar amount of cooking space up-top but slightly less in the main oven.
What about cleaning?
Some ovens come with stay clean catalytic liners - on the back and sides or just the sides - that absorb grease; just whack the temperature up to burn it off after cooking. And all ovens come with enamel interiors that make wiping up spillages really easy.
