Utilities & Hidden Costs During a House Sit: Who Pays?

Home > Blog > Utilities and Hidden Costs During a House Sit

Quick Facts

A week before I was due to fly to France for a five-month house sit in Montanel, the homeowner asked me to contribute €500 per month toward house and car expenses. I had already bought flights, sorted the visa, and arranged everything. Saying no meant the whole plan collapsed. I said yes, paid it, and the sit itself was a good experience.

I would not do that now. I would decline, report the listing, cancel, and move on. Not because €500 is necessarily the wrong number for five months. It might be reasonable in some arrangements. But because raising it a week before arrival, after everything had been agreed, is a manipulation. The right answer to that situation is always to have it disclosed at the start, agreed in writing, and built into the decision to apply. Everything else is a trap.

That Montanel experience was fourteen years ago, before Caro and house sitting as we know it. Based on 20 sits across 12 countries with TrustedHouseSitters, here is the honest guide to who pays for utilities, what the exceptions look like, and how to handle any financial surprise before it derails a sit.

The General Rule: Homeowners Cover Utilities

The house sitting exchange operates on a simple principle: the sitter provides services that would otherwise cost the homeowner significant money. Daily pet care, home security, mail collection, property maintenance. And in return receives free accommodation. No money changes hands in either direction.

Within this framework, utilities are the homeowner's responsibility. Electricity, gas, water, heating, cooling, and WiFi are costs the homeowner would incur whether the property was occupied or not. A sitter's incremental consumption. A few extra showers, a few hours of laptop charging, cooking their own meals. Is negligible relative to the standing costs and the services the sitter is providing in return.

The equal exchange argument runs in both directions. The homeowner saves on boarding costs, home security, property maintenance, and garden care. The sitter saves on accommodation. Neither party is doing the other a favour. Both are receiving something of genuine monetary value. Our is house sitting worth it guide breaks down exactly what that value looks like in numbers. Within that balance, asking a sitter to additionally pay for utilities is asking for more than the exchange provides. And in most cases it provides far more to the homeowner than they recognise.

This is the community consensus across all major house sitting platforms. Aussie House Sitters, House Sitters UK, House Sitters Canada, and Nomador all operate on the same principle.

See our Aussie House Sitters review and Nomador pricing guide for how these platforms approach the arrangement generally.

The Long-Sit Exception

The one broadly accepted exception involves very long sits. Typically six weeks or more. At that duration, the sitter's presence represents a more meaningful contribution to variable costs, particularly heating and cooling in extreme climates.

However, even this exception comes with a critical condition: it must be disclosed in the listing, discussed before the sit is confirmed, and agreed in writing. A homeowner who raises a utility contribution after confirmation, during the sit, or at arrival has violated the terms of the exchange regardless of the sit's length. The obligation to disclose financial expectations is absolute and exists from the moment a listing is posted.

Caro and I are currently in a six-month sit in Portugal. No utility contribution was agreed and none was requested. What we provide instead is considerable: daily garden watering, chicken care, cat care and medication, house airing to prevent damp, maintaining the property so the owners return to something intact rather than something they have to restart. The water we use is primarily for the owners' garden. The electricity we use is minimal. Two laptops and lights at night. In summer in Portugal we use no heating.

Could a homeowner of a six-month sit justify asking for utilities? Perhaps in a specific arrangement, with specific circumstances, agreed from the very beginning. In practice, I cannot construct a scenario where a homeowner who truly understands the value being provided would feel the exchange was imbalanced in their favour. If anything, a six-month sit compounds the value delivered to the homeowner with every additional month. A garden that would have died is maintained, a property that would have developed damp is aired and inhabited, pets that would have been rehomed or boarded are living their normal lives without interruption.

The Portugal "Money" Situation

When Caro and I were still in Montenegro, the welcome guide for our current Portugal sit arrived and mentioned that there was money that would be discussed when we arrived. We were worried immediately. We did not want to lose the opportunity but we equally were not prepared to arrive and be told about an unexpected financial expectation.

We wrote a clear, warm, positive message asking for clarification before we left Montenegro. The homeowners replied promptly: the money was for pet food. The cat can be fussy and might need a different brand from time to time. They would leave us money to buy it if needed.

That was a complete relief and made us more excited for the sit. But the process of asking the question. Before we were too far invested to turn back, before we had made any further commitments. Was the right approach. The lesson is not that homeowners are always hiding something when financial language appears in a welcome guide. The lesson is that ambiguity about money in a house sitting arrangement should always be resolved before arrival, and you should always feel comfortable asking for that clarity.

What to Do When a Financial Surprise Arrives

There are three moments when a financial request might arrive unexpectedly. Each has a different appropriate response.

Before the sit is confirmed, after initial enquiry. This is the best possible time for a surprise to surface. You have not committed to anything. The appropriate response is a calm, direct conversation about whether this arrangement works for you. If it does not, withdraw the application. The homeowner who discloses financial expectations at this stage is doing the right thing, even if the expectations themselves are unreasonable.

After confirmation but before arrival. This is the Montanel situation. The appropriate response now, compared to fourteen years ago, is clear: decline the addition. Explain that the arrangement was confirmed without this element and you are not able to agree to it. If the homeowner is reasonable, they will withdraw the request. If they are not, cancel the sit and report the listing. Our how to cancel a sit guide covers the platform-specific process, and our misrepresented listing guide covers the escalation path.

After arrival. Any financial request that surfaces after a sitter has moved in is, at best, a serious breach of the arrangement and, at worst, a form of financial manipulation. The sitter is in the most vulnerable position at this point. They are in a property they do not own, with pets in their care. The appropriate response is to decline clearly, document the request in writing immediately, and contact the housesitting platforms support. You do not owe compliance because you have already arrived.

The Safety Principle: Never Be a Sitting Duck

The Montanel experience taught me something beyond the specific issue of utilities. I was in a situation where I had made all my plans around a single house sit. Flight booked, visa sorted, accommodation arranged. And when the terms changed a week before departure, I had no good alternative. I was a sitting duck.

That is the version of house sitting that leaves you vulnerable to exactly this kind of manipulation. The homeowner who raises a financial demand late in the process is counting on the sitter being committed enough that walking away feels impossible.

Caro and I travel in the VW T4 campervan. If a sit falls through or the terms change unacceptably, we have a base. We do not rely on any individual sit as our only option. House sitting is the cherry on top of our travels, not the whole cake. Portugal was already on our route. The six-month sit aligned with our plans rather than defining them.

This safety principle applies even for sitters who are not campervanning. The practical version is: never confirm a sit that is so central to your plans that you cannot afford for it to fall through. Have a fallback. A friend's place, a short-term rental budget, a route that does not depend on a single sit. Our campervan travel between house sits guide covers how we approach this structurally, and our building trust guide covers the mindset side of not becoming dependent on any single outcome.

Other Hidden Costs to Be Aware Of

Utilities are the most common hidden cost discussion in the house sitting community. Other costs occasionally surface that are worth knowing about.

Pet food and consumables. The homeowner should provide all pet supplies. Food, medication, litter, treats. This is standard and non-negotiable. If you are expected to purchase anything, the homeowner should leave money for it (as in Portugal) or reimburse you immediately. Do not absorb pet food costs as part of the exchange.

Cleaning products. If you are expected to maintain a specific cleaning standard, the products should be in the property. A sitter buying cleaning products out of pocket for the homeowner's home is an imbalance that should never happen.

Garden supplies. Seeds, fertiliser, specialist plant food. If the garden requires these during the sit, the homeowner should provide them or leave budget. We are here to maintain what exists, not to invest in it.

Parking fees. Some urban sits involve parking costs for the sitter's vehicle that are not obvious from the listing. Ask about parking availability and any associated costs in the pre-sit video call if you are travelling by car or van.

Any cost that emerges during a sit that was not disclosed upfront follows the same principle as utility disputes: document it, raise it with the homeowner, and contact the platform if it becomes a genuine dispute.

Frequently Asked Questions

• Who pays for utilities during a house sit?

  The homeowner covers all utilities as part of the exchange. Electricity, gas, water, heating, cooling, and WiFi are the homeowner's costs regardless of whether the property is occupied. A sitter's incremental usage is negligible relative to the services they provide. Any expectation that the sitter contributes must be disclosed before the sit is confirmed. Not after arrival.

• Can a homeowner ask a sitter to pay toward utility bills?

  Only if it was disclosed in the listing and agreed before confirmation. For very long sits of six weeks or more, a contribution discussion is not unheard of in the community. But even then, disclosure must come at the start. A homeowner who raises utility costs after confirmation or after arrival has violated the terms of the exchange and the sitter is within their rights to decline.

• What should I do if a homeowner asks me to pay bills after I arrive?

  Decline, document the request in writing, and contact TrustedHouseSitters support. You do not owe compliance because you have already arrived. The financial terms of a sit are fixed at confirmation. Any addition that surfaces afterwards is a breach. Our misrepresented listing guide covers the escalation process.

• Does a six-month house sit change who pays for utilities?

  Not automatically. A longer sit means more sitter presence but also more sitter contribution. More maintenance, more pet care, more accumulated value delivered to the homeowner. Both sides of the exchange scale with length. A contribution discussion on a six-month sit is possible but must be disclosed from the beginning, agreed in writing, and proportionate to the arrangement.

• Should I ask about utilities before confirming a sit?

  Yes. Particularly if the welcome guide mentions money or if the sit is longer than a month. Ask directly: what are the financial expectations for this sit? A homeowner with nothing to hide will answer simply. Vagueness on financial terms is a warning sign worth investigating before you commit.
