Ask a question about this product

I have tried several different compatible ink cartridges for my HP Deskjet printer and none of them have been any good. If they work, the quality of the print is poor, but often one of the colours doesn't even work properly.

Your website is showing this as an original HP 45 high capacity ink cartridge for only £3.70 plus VAT and also the original HP 78 high capacity tri-colour ink cartridge for just £7.99 plus VAT. I assume at these prices these are genuine HP cartridges that have been refilled? If that is correct, then that is what I'm looking to try as I hope this will be similar to the original in quality unlike the compatible ones.

Can you confirm these are genuine HP cartridges refilled. Thanks.


Hi Roy,

I'm afraid this low price for the HP original is incorrect, sorry about that. We're getting it fixed now.

As you've had a problem with several refills I would advise trying some originals as is they fail you'll know there's a problem with your printer. If they work then you'll know you just had some faulty inks.

Our Refilled HP inks should always provide a result as good as an original HP inks, for this reason all of our products now have the same 12 month quality assured guarantee. So if you ever have an issue just give us a call or drop us an email and we will sort everything out for you.

If you would like to give our refills a go or order some originals from us please feel free to place an order online or give me a call to place an order for you.

If there's anything else we can help you with please let me know. Beth.
