The following are some of the sites specialized on UK hotels.

Travelstay will show cheap rooms across the UK including hostels and halls of residence. Travelodge offers £19 a night rooms, yet you will have to book before 3 weeks.

If you regularly stay at hotels it is better joining a directory club. For this you will need to pay a fixed amount of £30 to £60 per annum and you will accommodation from a directory of hotels. This is only for staying and you will require paying additional amounts for having food. Travel-offers is one of those and covers the UK.

Tesco Club Card vouchers which are rewards vouchers from in-store spending can be used to get cheap hotel rooms. This is useful as a £5 voucher is worth four times face value and there are a range of hotels which accept the vouchers.
