Overview
Most working-away arrangements in the UK follow the same shape: travel to site on Sunday night or Monday morning, work four or five days, go home on Friday. The accommodation that fits is the Monday to Friday let, also written Mon-Fri or weekday let, and it has its own pricing, rules and misunderstandings. This guide answers the questions people actually ask about it, with 2026 figures and the sources behind them.
In short
A Monday to Friday let is a room or whole property occupied during the working week and left empty at weekends. In 2026 a bed in a shared contractor house in a regional city typically costs £25 to £45 per person per night, against a regional hotel room at £70 to £100 with no kitchen, according to industry price guides published this year. The CIJC lodging allowance is £53.69 per night from 20 July 2026, the benchmark many employers use for budgets. Weekday lodgers in someone's home are licensees rather than tenants and sit outside the Renters' Rights Act reforms that started on 1 May 2026; a whole property let to a crew is usually run as short-term serviced accommodation.
What a Monday to Friday let actually is
SpareRoom, which has run a dedicated Monday to Friday section for years, describes it simply: the lodger occupies the room during the week and is elsewhere at weekends. That covers two different products. The first is the weekday lodger arrangement, where a homeowner lets a spare room to one person who arrives Monday and leaves Friday; it suits an individual contractor or a site manager on a long assignment. The second is the whole-property crew let, where a builder or rail contractor takes a three or four-bedroom house for a gang of four to eight and pays a weekday or a seven-night rate. Both are sold as Monday to Friday, but the second is closer to serviced accommodation than to lodging, and the price, paperwork and tax treatment differ. The contractor accommodation UK guide covers the whole-property market in more depth.
Who uses weekday lets in 2026
Demand comes from work that is a long way from home. The CITB Construction Workforce Outlook published on 30 July 2026 forecasts that the industry needs an average of 41,200 extra workers a year between 2026 and 2030, roughly 206,000 in total. Programmes such as Hinkley Point C, HS2, Sizewell C and the Lower Thames Crossing draw labour from across the country, and most of those workers keep a home elsewhere. Add rail engineers, wind technicians, locums and film crews, and the market is larger than most hosts assume.
