Designing the concrete slabs - Eurocode 2

I noticed that it's easy to feed the moments to Eurocode equations and get the reinforcement required etc (of course with many checks in between to design it properly).

We still need to calculate the moments before we feed it to Eurocode.
However, in Eurocode 2, I didn't notice easy method to calculate moments as BS8110 had in it.

So, I was wondering if we can use the method stated in BS8110 as there's a way to calculate moments easily (at the ends, sagging, hogging etc) with coefficients (BS8110, table 3.14, page 38).

Does Eurocode2 have such easy way or we have to rely on BS8110?

I know mixing two codes together is not good. But I don't really see a problem as well in this case as it serves two seperate things. Am I correct or wrong?
I don't want to make the calculations complicated, I want to design fast, I only want to make safe structures for real-life situations. So, It's ok if it's conservative and bit expensive than precise FEA methods.

I'm not quite sure if the BS8110 coefficients method is only for rough calculations and not for serious design. However, I think they have included it NOT for rough calculations, and ok for real-life design.

Is it ok to use it that way? Plugging the BS8110 coefficients --> get design moments --> input of Eurocode 2 --> safe slabs for real-life use?

You are right at this point. Eurocode 2 is silent for specific guidance on determining moments and shear forces. This is valid for other topics since it is European practice to give principles in the codes . If the corners of slabs are prevented from lifting, the coefficient method can be used .
You can use the coeff. given in any structural engineering book, Betonkalender , BS 8110 .
Other methods FEM , Plate grillage method,...
