Late arrival

You don't say which terminal you will be arriving at.

Terminal 5 has a Sofitel London Heathrowactually attached to it. Get off your plane, clear customs, go to bed. Great hotel but not cheap

Terminal 4 has a Hilton London Heathrow Airport Terminal 5 attached. Same idea plus there is the yo hotel inside the terminal (never stayed there)

All the other Hotels that serve Heathrow will require you to catch either a taxi or a bus to get to them but will probably be cheaper.

So if priority is sleep and you are not looking for cheap, there are options

There are a few hotels that circle round the air port. Here is the address of one of them.

420 Bath Rd, Longford, West Drayton UB7 0EA, UK.

It is a company chain called Premier Inn London County Hall Hotel which also means there is also others in liverpool if you need one 

cost is about £90 -100 per night. 

Yotel HQat Heathrow is another option that is not expensive and would let you get to sleep sooner to get up in the morning to travel and catch your train.

I would have agreed with the person who suggested going to Paddington via the Heathrow Express or Heathrow Connect, unfortunately it stops running at just about the time your plane lands.

If money is a concern or you don't care if you see anything of London, I would Priceline or Hotwire a Heathrow hotel or check out the prices on the Ibis Heathrow.  You still have to take a cab to get there and then get up in the morning and go into central London either by tube, HEX, HEC or taxi/transfer service.

If money is not a concern or you want to see something in London, even with your brief amount of time, I would prearrange for a car service which is cheaper than a taxi and get a hotel near Euston.  That way if you want to go for a wander in the morning or see anything of London, you have a place to leave your bags.  You can't do that with a Heathrow hotel.

I stayed at the Heathrow Lodge Hotel not too long ago. You can take a bus there (free), 10 minute ride, tops;  it is totally basic:  I had just a (small) room with a bed, bath across the hall. Absolutely no frills (ie: no TV, no phone, etc.)  Relatively cheap.  There is a bus schedule back to the airport (approx. every 20-25 min.)  It gave me a comfortable place to sleep, rather than trying to sleep at the airport. You must go back to the airport to catch the Tube, Express Train... don't know about Virgin trains (if they're different from the others).

Are you staying in London, or continuing onward? If staying in London, just go directly to your hotel in town. Connections are easy, check out the Heathrow Express train directly into the city in minutes. If you want to stay by the airport, the Renaissance London Heathrow Hotel is close and convenient.

Hi Liane,

There are a few details that are missing from you inquiry that may prove helpful in answering.   Since I don't have those details I'm going to make some assumptions.

• First assumption is that you're leaving for Liverpool in the morning.
  
• The second is that you're unfamiliar with the London/Heathrow area.
  
• Finally, I'll assume that you're going to be tired, and not want to mess around trying to navigate the city at night.
  

Given the time you're getting in and your departure to Liverpool, I think you may wish to consider this course of action.

1. Using a discount site (Hot Wire, Priceline, Trivago, ect) reserve a room close to the airport.  There are over 35 hotels near the airport.  Some are quite nice, others.....    However, most rooms can be had for under $100.  Just type in Heathrow into your search, and they'll all pop up.  You can then arrange them by distance, price, or whatever criteria you please.
2. Hail a taxi from whichever terminal you exit.   Have them take you to your hotel of choise.
   
3. When you check-in, ask the front desk, or concierge, for a recommendation on how to get to Euston Station.  This is the station from which the Virgin Trains depart on their way to Liverpool.  You may need to take another taxi, or use the Tube.  Whatever it is, ask about fares, time allowances, your luggage, and whatever else you think is pertinent.
   

Now you should be armed with enough information to face the next leg of your journey, and enough time to rest up for it.

Happy Travels!

Hi, Liane,

After reading the valuable ideas from the other contributors and considering where you're headed and the time of your late arrival, here's what I would do:

• If money is not a consideration, hail a black cab outside your Heathrow Airport terminal, as Sean Kelly said. It should take no more than an hour for you to arrive in London and will certainly be comfortable and the cabbies are usually quite amiable and will give a perfect first impression of the city. This is the most straightforward and convenient and simple option for weary travellers, and, if you are travelling with more than 2 people, could also be an economical one as well.
• If money is a consideration, take the Heathrow Express, as Steve Dickey suggested. Once the train leaves, it will usually take no more than 15 minutes to Paddington Station where you can then hail a black cab to your hotel, wherever it may be.
• If you're exhausted at this point, stay near Paddington Station. Norfolk Square is about one block from Paddington Station and has a few hotels and requires a very short walk. My favorite hotel in the area, though, is the London Elizabeth Hotel for its lovely rooms, proximity to Hyde Park (one of my favorite places in London) and the many restaurants and pubs in close proximity. Another good hotel nearby is Rhodes Hotel in Sussex Gardenswhere the owner is extremely hospitable and the included breakfast is hearty and sustaining. Hyde Park has beautiful paths for a morning walk and a few different cafes or coffee shops where you can buy coffee or tea and pastries. (Also, if you stay in this Lancaster Gate or Paddington area of London, for lunch the next day, try my favorite pub, The Victoria  for its warmth, ambience, excellent selection of beers and a great fish and chips, and its inviting library area upstairs.) 
• You can also take a cab from Paddington Station that night to a hotel in the Euston Station area which is where you will catch your train the following day to Liverpool. The The British Museum would take no time at all by cab from Euston Station area and would make for a nice few hours before you catch your train. 
• St Pancras International is available to you from Heathrow via the underground, and is quite close to Euston Station but you will be tired and navigating the tube and paying for tickets with your luggage and stairs would be a nightmare. I don't recommend it.

I hope your (very short) time in London entices you to return for a longer stay!

Even at that late hour, I'd still rather stay closer to Euston Station than at the airport.  The express train to Paddington stops running at around the time you land, so I'd cab or Uber it to a hotel near Euston, so that although you'll be getting to the hotel very late, you can sleep in come morning and have a very short, stress-free trip to the station to catch your train.

The Wesley Euston Hotel & Conference Venue, Thistle Euston Hotel Hotel Pullman London St Pancras and St. Pancras Renaissance London Hotel are some good hotels near Euston Station.
