Holiday Let Running Costs UK: A Practical Owner Checklist

Booking and platform costs

Most holiday lets rely on at least one booking channel. Host fees, payment processing, channel manager fees and booking commissions can reduce revenue before you see it. If you use a traditional holiday cottage agency, the commission may be much higher than a simple platform fee but may include marketing and guest handling.

Model platform fees as a percentage of revenue. If you expect a mix of direct bookings, Airbnb, Vrbo and agency bookings, use a blended percentage rather than the lowest fee. It is better to be pleasantly surprised than to discover the base case assumed a direct-booking machine you have not built yet.

Cleaning, laundry and changeovers

Cleaning is one of the most important operating lines. It includes cleaner time, laundry, consumables, restocking, travel, damage checks and sometimes waste handling. Remote locations can be harder to staff, and larger properties can require more people on changeover day.

Guest cleaning fees may not cover the owner cost. If a platform makes a high cleaning fee unattractive to guests, the owner may absorb part of the cost through the nightly or weekly rate. Model cleaning revenue and cleaning cost separately so you can see whether cleaning is profitable, neutral or a drag on cashflow.

Utilities and services

Holiday-let utilities can be higher than long-term rental utilities because guests have little incentive to reduce use. Heating, hot water, laundry, hot tubs, EV charging, broadband and streaming services can all contribute. Older cottages and lodges with poor insulation may be especially sensitive in winter.

Include electricity, gas or oil, water, broadband, TV licences or subscriptions where relevant, waste collection and any estate services. If the property has electric heating or a spa facility, run a more cautious utility scenario before relying on a slim profit margin.

Maintenance, repairs and replacements

Short-stay properties experience frequent use. Mattresses, sofas, appliances, cookware, paintwork, flooring and outdoor furniture can wear faster than expected. A single major repair can wipe out a good month, so a maintenance reserve is a sensible modelling habit.

Many early calculators use a percentage of booking revenue, such as 5%, as a simple reserve. That will not match every year, but it gives the model a recurring allowance. For older properties, coastal homes, large gardens or luxury specifications, consider adding more.

Compliance, insurance and local charges

Holiday-let owners may need specialist insurance, fire risk assessment, gas safety checks, electrical checks, PAT testing, legionella review, planning review, licensing checks or business rates advice depending on the property and location. Requirements can change, so verify them before purchase.

Also include council tax or business rates, service charges, ground rent where applicable, estate charges, waste collection, accountancy and professional fees. These costs may feel administrative, but they can materially affect net yield, especially on lower-priced properties with modest revenue.

Before you rely on the scenario

Treat the numbers as a decision screen, not a decision in themselves. A useful holiday-let model should help you decide what to research next: which costs need quotes, which revenue assumptions need evidence, which finance terms need broker confirmation and which legal points need a solicitor. The output is strongest when each assumption has a source, even if that source is only an agent estimate, comparable listing review or supplier quote at the early stage.

Keep a simple evidence file for the property. Save comparable listings, agent income estimates, cleaner quotes, management fee schedules, insurance indications, service charge details, utility assumptions, mortgage illustrations and notes from calls. When the calculator shows a strong result, the evidence file helps you test whether that strength is real. When it shows a weak result, it helps you see which assumption would need to change before the property is worth more time.

Finally, run at least three versions of the deal. The base case should reflect your honest current view. The downside case should reduce revenue and increase costs enough to feel uncomfortable but plausible. The upside case can show what happens if the property performs well, but it should not be the only case used to justify an offer. A deal that survives a cautious downside is usually easier to own than one that needs every assumption to land perfectly.

If the scenario changes materially after one quote, one fee schedule or one mortgage rate update, that is useful information. It means the margin of safety is thin and the purchase needs more evidence before you spend money on surveys or legal work. The best early analysis makes uncertainty visible while there is still time to negotiate, pause or compare another property.

Use the guide with your own numbers

The next step is to turn the assumptions into a scenario for the actual property you are considering. Start with the free holiday-let calculator, compare the model in the premium spreadsheet, or request a practical property review if you want a structured second look.
