Unfortunately I did not look after this plant very well. I moved it from my kitchen where it was thriving into my office where it has dried up due to the heat and unfortunately I may have underwatered it.
I have since moved it back into the kitchen and have put some diluted plant feed in and watered it, but it is still looking like this after five days.
Is there anything else I can do to bring this back to life as it is a beautiful plant?

So... That looks like a palmetto.
I saw the plant card that came with and enlarged pic but still couldn't read it.

I'd plant that outside... should grow in your environment easily... they grow around here as naturals.

I think your palmetto will recover.... they like plenty of moisture but do tolerate drought... often grow in shaded conditions, but probably would appreciate any natural light you can provide.

Or, (Mediterranean ) fan palm
I have had a fan palm in progressivley bigger pots since sprouting from seeds 2009. Wants bright light, seems to like being watered regularly but I have stressed mine many time and not killed it.
The current leaves may be dried but the plant still alive. Have patience, you may need to wait for new leaves from The center.

Thank you everyone this is classes a houseplant. I will try and take a picture of the card. Should I not trim any of the leaves and just leave it?

My first thought was also a European Fan Palm (Chamaerops humilis) a/k/a Mediterranean Fan Palm which will likely do better if you can give it much higher light.

That label is so generic as to be about useless.

We need to see the other side of card...

I think that any house plant is an outside plant in it's natural environment...

We need to identify just what the plant is before we can give any real cultural advice...

Edit... if this plant is a European Fan Palm... you want to avoid over-watering...

As far as chopping on the plant?
Don't.

Don't cut anything off until it turns brown. At this point, the best thing you can do is give it lots of light and keep it moist but never soggy wet. Palms are not the fastest growing plants so expect it to look worse before it gets better. For a while. Like months.
