The eight weeks between tenancies worked from bookings to net contribution, with the occupancy at which summer letting stops paying.
Summer letting is usually worth doing, but it is worth far less than the bookings suggest. On an illustrative 500-bed scheme, eight summer weeks at 45 per cent occupancy and £45 a night bring in £567,000, and after VAT, booking commission, turnaround cleaning, utilities and the season's extra staffing the scheme keeps £169,325, 29.9 per cent of the gross and £338.65 a bed. It breaks even at 16.7 per cent occupancy; below that, the building is better left empty or handed to the refurbishment team.

A 500-bed purpose-built scheme lets its rooms on 44-week tenancies, which leaves eight weeks, 56 nights, between one cohort moving out and the next moving in. The operator can sell those nights to summer schools, interns, conference delegates and tourists through booking channels. Short-stay accommodation is a different business from a student tenancy: it is charged VAT, it is sold through intermediaries, every stay needs a turnaround clean, and the building needs a staffed reception. All figures below are illustrative.
| Item | Value |
|---|---|
| Beds / summer nights | 500 / 56 |
| Available bed-nights | 28,000 |
| Summer occupancy | 45% |
| Rate per bed-night, VAT inclusive | £45.00 |
| VAT on short stays | 20% |
| Booking channel commission (on net revenue) | 15% |
| Average stay / cleaning and linen per stay | 4.0 nights / £30.00 |
| Utilities per occupied bed-night | £3.00 |
| Seasonal staffing (24-hour reception, housekeeping supervision) | £60,000 |
| Local property tax allowance for non-student occupation | £40,000 |
The last line is an allowance, not a rule: whether non-student occupation triggers council tax or business rates, and how much, depends on the scheme and has to be checked case by case.
Occupied bed-nights = 28,000 × 45% = 12,600
Gross bookings = 12,600 × £45.00 = £567,000
Net of VAT = 567,000 / 1.20 = £472,500 (VAT of £94,500 belongs to the tax authority)
Commission = 472,500 × 15% = £70,875
Cleaning = 12,600 / 4.0 = 3,150 stays × £30.00 = £94,500
Utilities = 12,600 × £3.00 = £37,800
Fixed costs of the season = 60,000 + 40,000 = £100,000
Net summer contribution = 472,500 − 70,875 − 94,500 − 37,800 − 100,000 = £169,325
| Line | £ | Per bed £ |
|---|---|---|
| Gross bookings | 567,000 | 1,134 |
| Less VAT | −94,500 | |
| Less commission | −70,875 | |
| Less cleaning and linen | −94,500 | |
| Less utilities | −37,800 | |
| Less staffing and local tax | −100,000 | |
| Net summer contribution | 169,325 | 338.65 |
The scheme keeps 29.9 per cent of what guests pay, a 35.8 per cent margin on net revenue. Per bed, £338.65 is about 4.1 per cent of the £8,360 a bed earns over a 44-week tenancy at £190 a week. It is real money, but it is a top-up, not a second rent roll. Set it against the alternative of letting the same rooms on 51-week tenancies: seven more weeks at £190 is £1,330 a bed of rent before any rate concession, nearly four times the summer contribution, which is why the tenancy length matters more than the summer programme when student accommodation is valued per bed.
Work per occupied bed-night. The net rate is £45.00 / 1.20 = £37.50. Commission takes £5.63, cleaning £30.00 spread over a four-night stay takes £7.50, and utilities £3.00, leaving £21.38 a night towards the season's fixed costs.
Break-even bed-nights = fixed costs / contribution per bed-night = 100,000 / 21.38 = 4,678
Break-even occupancy = 4,678 / 28,000 = 16.7%
Excel: =Fixed/((Rate/(1+VAT))*(1-Comm)-Clean/Stay-Util)/(Beds*Nights)
| Occupancy | £35 a night | £45 a night | £55 a night |
|---|---|---|---|
| 20% | −19,967 | 19,700 | 59,367 |
| 30% | 20,050 | 79,550 | 139,050 |
| 45% | 80,075 | 169,325 | 258,575 |
| 60% | 140,100 | 259,100 | 378,100 |
The fixed costs make the result steep at the bottom: at 20 per cent occupancy and £35 a night the season loses money. The average stay matters too. Shorter stays multiply turnaround cleans, so a programme of two-night tourist stays at the same occupancy keeps markedly less than a block booking by a summer school for the whole eight weeks, which is why operators prize the latter even at a lower rate.
Summer is also the only window for refurbishment, and at 45 per cent occupancy the season is limited by demand, not beds. Holding 100 beds back for works leaves 400 beds and 22,400 bed-nights, still well above the 12,600 sold, so if guests can be placed in the open rooms the works cost almost nothing in summer contribution. The trade-off only bites in a strong summer: here, once occupancy of the whole building would pass 80 per cent, every bed held back turns guests away.
The common mistake is putting gross summer bookings into net operating income: £1,134 a bed rather than £338.65. Capitalised at an illustrative 5.50 per cent, the gross figure would add £10,309,091 of value; the net contribution adds £3,078,636, and many buyers and valuers treat even that cautiously because summer demand is re-sold from nothing every year. The second mistake is forgetting the VAT: a student tenancy is usually exempt, short-stay accommodation is not, so the same £45 a night is £37.50 to the owner. The way summer income sits in the full year's NOI is worked in how to calculate NOI for a student housing scheme.
The book's model treats the summer with its VAT and its local tax as part of the ten-year cash flow, and the free workbook for this case lets you replace these assumptions with your own scheme's.
Less than the booking figures suggest. In this illustrative 500-bed case, 12,600 bed-nights at 45 pounds gross bring in 567,000 pounds, but after 20 per cent VAT, 15 per cent commission, cleaning, utilities and 100,000 pounds of seasonal fixed costs the scheme keeps 169,325 pounds, 338.65 pounds a bed, about 4.1 per cent of a 44-week academic rent.
Divide the season's fixed costs by the contribution of one occupied bed-night. Here 100,000 pounds of staffing and local tax, over 21.38 pounds a night after VAT, commission, cleaning and utilities, needs 4,678 bed-nights: 16.7 per cent of the 28,000 available over eight weeks.
It can be, but net, not gross, and with caution, since it depends on short-stay demand that changes every year. Capitalised at an illustrative 5.50 per cent, the 169,325 pounds of net summer contribution here is worth about 3.08 million pounds; the gross bookings would suggest 10.31 million, more than three times as much.
