Finding a place to live is a priority on any immigrant's list. If there are not enough funds set aside to purchase a home when first moving to the UK, there are other options available. The most cost effective plan is for the immigrant to stay with family or friends at first. This happens often when a family begins to immigrate in waves, with members arriving over a span of time. When one can get by with paying either nothing, or sharing costs, it's easier to settle than if housing expenses were shouldered alone.
If one doesn't have access to this arrangement, rentals are the other way to go. Flats are available in many styles, from the very small studio flats which are contained all in one room, to multi-bedroom flats. Private homes are also available for rental, and hostels are handy for short term accommodations. Listings can be found in the classified sections of area newspapers, in real estate booklets, and on the internet. One can also visit the offices of a real estate company that specialises in leases and speak directly to an agent. There is more involved in figuring out what an affordable rental will be than the monthly charge. Some rentals include various utilities, and some don't. Rentals that include certain amenities can sound more expensive, and yet if the amenities are acquired separately, they could run the monthly cost up. Do the maths to ensure you are getting the best deal.
Consider advertising or answering an advertisement for a roommate. Halving costs is a good way to economise, but care must be taken when choosing to accept this option with a stranger.
These arrangements are ideally made before ever setting out for the UK. Good housing can be found on the spur of the moment, but the pressure to find something quickly can lead to making rushed and unwise decisions. On the upside, finding accommodations after arriving does give one the chance to see the rooms before deciding.
Before signing any papers, which are legal documents, be absolutely sure you understand the terms of the lease and all fees that are applicable. Ask about council taxes, which cover such things as refuse removal. If your English is poor, or if the legal terminology is over your head, request a copy of the lease so that you can take it to someone who will understand it and explain it to you.
