A SPARQL question - How can I improve this query?

Question

I have put the filter parameter, the LSOA code E01001117, in the PREFIX. I guess this is not best practice? Although the query work, I am not convinced I have an optimal query. Any comments welcome!

SELECT ?LSOACD ?LSOANM ?LSOAstatus ?LADCD ?LADNM
