Where can I buy a small-ish decorative fireplace surround?

[Startingagainandagain]

When I bought my 1930 house there was an old gas stove where one of the fireplaces use to be.

I removed the gas stove as it was faulty and installed a new electric one with flame effect. I would now like to add a fireplace surround purely for aesthetics.

What I am seeing on places like Facebook Marketplace is either too big and heavy for my small terrace or too expensive.

Could anyone suggest where else to source this?

How small is it? Budget?
Reclamation yard?
I'm not sure of the size you want, but maybe 1 of these? https://www.screwfix.com/c/heating-plumbing/fire-surrounds/cat831108?cm_sp=managedredirect--hvac--firesurrounds

Thank you for the links!

These would be OK for my budget.

Other places to try could be B&M, home bargains and B&Q.
