If you are talking personal effects you could consider unaccompanied baggage. We have done it twice from Qatar and it's much cheaper than freight or excess baggage.
Clearance at the UK end isn't difficult but you will have to attend the receiving airport customs office yourself. For large items you would need a receipt to show you have had them for the required period of time. I think it's 12 months but am not sure.
You would need to pack it yourself and prepare a detailed list of contents (that's required whichever way you send it).
