Serviced accommodation (SA) has become one of the UK's most profitable property investment strategies. Unlike traditional buy-to-let where rental yields hover around 5-7%, serviced accommodation investors regularly achieve cashflow returns of 15-30% annually. But these figures only work if you understand your numbers beforehand.
This guide walks you through calculating exactly how much you can earn from serviced accommodation in 2026, using real data and practical examples.
What Is Serviced Accommodation and Why Are Yields So High?
Serviced accommodation involves letting furnished properties on short-term contracts (typically 7-28 days) to corporate tenants, relocating workers, and leisure guests. It sits between hotel rentals and traditional long-term letting.
Why the yields are higher:
- Nightly rates: £60-£150+ per night (vs £400-600 monthly rent on traditional lets)
- Higher occupancy: Corporate contracts provide 80-95% year-round occupancy
- Premium pricing: Business travellers pay more than holiday guests
- Multiple income streams: Cleaning fees, early check-out penalties, and welcome packages add 10-15% to base revenue
- Lower void periods: Corporate tenants need consistent supply; you're not advertising weekly on Rightmove
The trade-off is operational complexity. You're running a small hospitality business, not just collecting rent.
The Basic SA Cashflow Formula
Before entering numbers into any calculator, understand the core equation:
Monthly Gross Revenue = Nightly Rate × Number of Nights Booked
Monthly Profit = Gross Revenue − Operating Costs − Debt Service
A typical calculation looks like this:
- 2-bedroom flat in Manchester
- £85 nightly rate
- 28 nights booked per month (90% occupancy)
- Gross revenue: £2,380
- Operating costs: £950 (utilities, council tax, cleaning, supplies, platform fees)
- Mortgage: £800
- Net monthly cashflow: £630
This equals a 7.5% net yield on a £100,000 purchase. However, most SA investors achieve 12-18% because they optimise pricing, reduce voids, and operate multiple properties simultaneously.
Breaking Down Operating Costs (The Hidden Killer)
Most new SA investors underestimate running costs. Here's what actually eats into your gross revenue:
Essential Monthly Costs (Per Property)
| Cost Category | % of Revenue | Monthly Example |
|---|---|---|
| Council tax | 2-4% | £50-95 |
| Utilities (gas, electric, water) | 4-6% | £95-145 |
| Cleaning & laundry | 15-20% | £355-475 |
| Furniture replacement fund | 2-3% | £50-70 |
| Supplies (toiletries, tea, coffee) | 2-3% | £50-70 |
| Insurance | 3-5% | £70-120 |
| Platform fees (Airbnb, Booking.com) | 3-5% | £70-120 |
| Maintenance & repairs | 5-8% | £120-190 |
| Property management/co-hosting | 8-12% | £190-285 |
Total: 45-66% of gross revenue
This is why using a proper SA cashflow calculator matters. Missing even two categories can inflate your profit projections by thousands of pounds annually.
When you require financial protection against potential guest damage or liability claims, landlord insurance specifically designed for serviced accommodation ensures your investment is properly covered—many standard landlord policies explicitly exclude short-term letting, leaving you dangerously exposed.
Regional Variations in 2026
SA profitability varies dramatically by location. Here's what current data shows:
London (Central)
- Nightly rate: £120-200
- Occupancy: 85-95%
- Net yield: 10-14%
- Best for: Corporate bookings, international tourists
Manchester, Birmingham, Leeds
- Nightly rate: £70-110
- Occupancy: 80-90%
- Net yield: 14-18%
- Best for: Budget corporate, university relocations
Secondary Markets (Nottingham, Bristol, Southampton)
- Nightly rate: £55-85
- Occupancy: 75-85%
- Net yield: 16-22%
- Best for: Highest net returns, lower property costs
Coastal Towns (Brighton, Bournemouth)
- Nightly rate: £65-120
- Occupancy: 70-80% (seasonal)
- Net yield: 12-16%
- Best for: Seasonal diversification
The highest net cashflow typically comes from secondary markets where property prices are £120,000-200,000 and nightly rates support 18%+ returns without operational bloat.
Using a SA Cashflow Calculator Effectively
A proper calculator should factor in:
- Purchase price and financing costs (mortgage, interest rate, fees)
- Occupancy rate (based on your market research)
- Nightly rate (seasonal variations if applicable)
- All operating costs listed above
- Tax liabilities (income tax, VAT if applicable)
- Void periods (typically 5-15 nights monthly for deep cleaning, refurbishment)
PropertyAlert.uk's SA Cashflow Tool includes built-in market data for UK regions, pre-populated cost benchmarks, and instant sensitivity analysis. You can adjust occupancy or nightly rates to see how profits change—essential for stress-testing assumptions.
For example, if your model assumes 90% occupancy but achieves 75%, does the investment still cashflow? A calculator instantly reveals this risk.
Real Example: A Working SA Investment
Let's walk through a realistic 2026 scenario:
Property Details
- 2-bed terrace, Leeds city centre
- Purchase price: £165,000
- Mortgage: £115,000 at 5.5% (25-year term)
- Your deposit: £50,000
Revenue Assumptions
- Nightly rate: £92 (weekdays), £105 (weekends)
- Annual occupancy: 82% (300 nights booked)
- Annual gross revenue: £28,920
Operating Costs (Annual)
- Council tax: £1,080
- Utilities: £1,320
- Cleaning/laundry: £4,320
- Supplies & toiletries: £720
- Insurance: £960
- Platform fees: £1,440
- Maintenance: £1,440
- Management/co-hosting: £2,880
- Total: £14,160
Debt Service
- Mortgage payments: £6,850 annually (approximately)
Annual Cashflow
- Gross revenue: £28,920
- Operating costs: −£14,160
- Mortgage: −£6,850
- Net cashflow: £7,910 annually (£659 monthly)
Return on Investment
- Annual cashflow: £7,910
- Your initial deposit: £50,000
- Net ROI: 15.82%
This assumes no major repairs, no voids, and 82% occupancy. A conservative investor might assume 70% occupancy, which reduces net cashflow to £3,890 annually (7.78% ROI)—still respectable given the leverage.
Tax Implications You Must Account For
SA income is treated as business revenue, not rental income. This changes your tax calculation significantly:
- Income tax: On all profits (basic rate 20%, higher rate 40%)
- National Insurance: Class 4 contributions (9% on profits between £11,908-£50,270)
- VAT: Potentially required if turnover exceeds £85,000 (voluntary registration possible below this)
- Wear and tear: You cannot claim the old 10% wear-and-tear allowance; you claim actual costs only
On the Leeds example above, your £7,910 net cashflow becomes approximately £5,100 after tax and NI (assuming basic rate taxpayer). This is why many SA investors structure holdings through limited companies—corporation tax (25% from 2025) plus dividend tax is often more efficient than self-assessment.
Stress-Testing Your Assumptions
The difference between projected and actual returns often comes down to assumptions you haven't questioned. Use your calculator to stress-test:
- Occupancy drops to 70%: How does this change your monthly cashflow?
- Nightly rate falls 10%: Does the investment still work?
- Operating costs rise 15%: Can you absorb this?
- Mortgage rate increases 1%: What's your new return?
A robust SA investment should remain profitable even if two of these variables move against you simultaneously.
Choosing the Right Tools and Support
Successfully forecasting SA cashflow requires discipline around assumptions. When structuring a portfolio of SA properties, many investors establish a limited company to optimise tax and liability. Formation specialists like 1st Formations allow you to set up an SPV quickly (from £52.99), ensuring your SA business is properly structured before you take on property.
Next Steps: Calculate Your Actual Returns
Theory only gets you so far. The real test is running numbers on properties you're actually considering.
Start by researching comparable nightly rates in your target market (Airbnb, Booking.com, and specialist SA platforms provide this data). Then estimate occupancy conservatively—aim for 70-80% if you're new to SA. Plug these figures into PropertyAlert.uk's SA Cashflow Calculator alongside accurate operating costs for your region.
Only when you've modelled three different scenarios—base case, conservative case, and optimistic case—should you seriously consider moving forward. SA offers genuine wealth-building potential, but only for investors who respect the numbers.
