House sitting, looking after someone’s home, pets and plants while they are away, is a genuinely low-cost business to start, since it needs almost no equipment or capital. The real barrier is not cost but trust: a homeowner is handing over access to their property, which means the business succeeds or fails on credibility and reputation far more than on marketing.
These are the factors that actually determine whether it works as a real business.
Trust is the entire product
A homeowner choosing a house sitter is making a decision based almost entirely on trust, since they cannot supervise what happens in their absence. References, a clear vetting process for yourself, and a professional, consistent way of presenting the service all matter more here than in most small businesses.
Building a track record through a first few clients, ideally people who can vouch for you personally or through a mutual connection, is usually how this business gets its genuine start before strangers will trust you with their home.
Get the liability and insurance side right
Consider liability cover for accidental damage or loss while responsible for someone else’s property, since a single serious incident without cover could be financially and reputationally damaging enough to end the business. Confirm any insurance provider is properly authorised through the Financial Sector Conduct Authority before buying a policy.
A simple, clear written agreement with each client, covering what is expected, emergency contact procedures, and what happens if something goes wrong, protects both sides and signals professionalism.
Price it as a real service, not a favour
Rates should reflect the actual responsibility involved: overnight stays, pet care complexity, and the property’s specific needs, rather than being priced as a casual favour for a friend. A genuinely professional house-sitting business commands a professional rate.
Specialising, whether in pet care specifically, high-value properties, or longer-term absences, can help differentiate the business and justify a stronger rate than competing purely on being available.
Register once it becomes a real income stream
Once house sitting moves from an occasional arrangement to a genuine, regular income source, it needs the same registration and tax treatment as any other business.
