How Much Does HMO Management Cost?

Full HMO management fees typically costs between 12% and 15% of gross monthly rental income, plus VAT. Across the UK the range runs from around 10% to 18%, depending on region, property size and service level. This is higher than standard buy-to-let management, which usually sits between 8% and 12%, because an HMO means more tenants, more turnover and more compliance work. On a five-room HMO bringing in £3,000 a month, a 14% fee works out at £420 a month, or £5,040 a year.

Here’s how those fees break down, what should be included, and the questions worth asking before you appoint an agent.

What is the typical HMO management fee?

Most agents charge a percentage of the rent they collect. For full HMO management, 12% to 15% is the most common bracket, and London and the South East tend to sit towards the top of it. Larger properties sometimes attract discounted rates, because the workload per room falls as the room count rises.

Check whether quoted fees include VAT. A 12% fee becomes 14.4% of your rent once VAT is added, a difference of £72 a month on £3,000 of rental income. Reputable agents publish fees inclusive of VAT, but plenty still quote the bare figure in conversation, so ask.

Average percentage fee for full management of HMOs

Fee guides and published agent schedules cluster around the same figures:

• Standard single let, full management: 8% to 12%
• HMO, full management: 12% to 15%, with some agents charging up to 18%
• HMO with rent protection or a guaranteed rent scheme: 15% and upwards

The gap reflects the workload. A five-room HMO is five tenancies, five sets of referencing, five deposits and five renewal dates. Rooms change hands more often than whole houses, communal areas need inspecting and cleaning, and licensing adds a layer of compliance a single let never faces.

Management fees feed directly into your net return, so factor them in when you calculate your rental yield.

Typical HMO management fee structures

Fees come in three shapes.

Percentage of rent. The standard model. You pay a share of whatever the property collects, so the agent earns nothing on an empty room.

Fixed monthly fee. A set amount per room or per property, whatever the occupancy. Predictable, but you pay the same during void periods.

Tiered packages. Most agents, Sturstons included, offer levels of HMO management: tenant find only, tenant find with rent collection, full management, and guaranteed rent schemes designed to provide consistent rental income whether rooms are occupied or not. Each step up costs more and takes more of the workload off your plate.

Percentage fees versus fixed monthly fees

Percentage fees align the agent’s interests with yours. Empty rooms cost them money too, which concentrates minds on filling voids quickly. Fixed fees give you a known cost for budgeting, and they sometimes work out cheaper on high-rent properties where a percentage stings. For most HMO landlords, percentage-based full management remains the better fit, because void reduction matters more than fee certainty.

Tenant-find and setup charges

On top of the monthly fee, expect one-off charges when a tenancy starts:

• Tenant sourcing: commonly 75% to 100% of one month’s rent per room, though some agents charge a flat fee of £250 to £500
• Referencing and Right to Rent checks: sometimes included, sometimes £30 to £60 per applicant
• Inventory, deposit registration and tenancy paperwork: often bundled into the setup fee, but not always

Sourcing fees cover the advertising itself, including listings on major portals such as Rightmove, plus viewings and negotiation.

These charges recur far more often in an HMO than in a single let. A whole-house tenant might stay three years. Rooms turn over annually or faster, and every changeover triggers a fresh setup charge with some agents. Over five years, changeover costs on a six-room HMO add up to a serious sum, so ask how they’re priced before you sign.

Renewal, inspection and maintenance fees

The other place fees hide is in the day-to-day running of the property. Common extras include:

• Tenancy renewal fees each time a tenant re-signs
• Charges for inspections beyond an agreed number per year
• A threshold on repairs, often £100 to £200, above which coordination fees apply
• Markups of 10% to 15% on contractor invoices
• Separate charges for gas safety certificates, EICRs, EPCs and PAT testing
• Licence application support billed as an add-on

None of these is unreasonable in itself. The problem arises when a low headline percentage is propped up by a long list of extras, leaving you paying more than an honest all-in fee.

What should be included in the management fee

A full management fee worth the name should cover:

• Marketing, viewings and tenant screening
• Referencing and Right to Rent checks
• Tenancy agreements and deposit registration
• Rent collection and arrears chasing
• Maintenance coordination and repairs oversight
• Regular inspections, including communal areas
• Licensing and compliance monitoring
• Direct tenant communication, so calls come to the agent, not you

If an agent’s quote excludes several of these, the percentage on the page is not the price you’ll pay. Ask for a full fee schedule in writing and compare agents on total annual cost, not the headline rate.

Questions to ask before appointing an agent

Six questions expose the true cost quickly:

1. Is the quoted fee inclusive of VAT?
2. What triggers extra charges, and how much are they?
3. Do you add a markup to contractor invoices?
4. How many HMOs do you manage in this area?
5. Do you know the licensing schemes run by my local council?
6. What is your average void period per room?

The last three matter as much as the first three. A cheap agent with no HMO experience costs more in empty rooms and compliance mistakes than a specialist charging a point or two more.
