Property management fees calculator (UK)

Put in an agent’s price list and see what full management really costs a year: the management fee, letting and check-in fees for every new tenant, admin fees and VAT. Works for a single let or an HMO let room by room.

What a letting agent charges, fee by fee

A property management fee is rarely one number. Agents price full management as a percentage of the rent, then add one-off fees each time a tenant moves in and a few yearly charges. The ranges below are the ones August’s calculator uses as UK market figures (August, checked 17 October 2026); your agent’s own price list is what counts.

Repairs come on top at the contractor’s price (Livdin Property, for one, says it adds no markup); ask whether your agent charges to arrange them. Also read the agreement for any fee for leaving the agency, or for keeping a tenant the agent found after you switch. It won’t show up in a yearly total, so it isn’t in the calculator.

How the calculator works it out

Rent collected is rooms × rent per room × 12, less the share of the year rooms stand empty. The management fee is a percentage of that, so an empty room costs nothing in management. New tenancies a year are rooms × 12 ÷ the average stay: six rooms whose tenants stay 18 months bring four new tenancies a year, and each one carries a letting fee and a check-in fee. Admin fees are added once a year, then VAT on everything unless your figures already include it.

A worked example: a six-room HMO

The calculator opens on a six-room house at £650 a room, with 3% voids, tenants staying 18 months on average, and an agent charging 12% management, a letting fee of half a month’s rent, £100 per check-in and £120 a year in admin, all plus VAT.

• Rent collected: 6 × £650 × 12 × 97% = £45,396 a year.
• Management: 12% of £45,396 = £5,448.
• Letting fees: 4 new tenancies × £325 = £1,300. Check-ins: 4 × £100 = £400. Admin: £120.
• VAT at 20% on £7,268 = £1,454.
• Total: £8,721 a year, about £727 a month or £121 per room, which is 19.2% of the rent collected: a 12% headline rate costing nearly a fifth of the rent.

The same fee list on a single let at £1,250 a month, with no voids and a tenant staying two years, comes to £2,739 a year including VAT, or 18.3% of the rent. In the HMO, turnover is the number to watch: if those six tenants stayed 12 months instead of 18, the letting and check-in fees would rise from £1,700 to £2,550 a year before VAT.

What is a typical property management fee in the UK?

There’s no regulated rate. August’s help centre puts the UK average at “broadly 10–12% of monthly rent”, with London agents at 12–15% and regional agents as low as 8%, excluding letting and renewal fees (August, 9 April 2026). Agents that publish prices online show the HMO premium plainly: Livdin Property in Holmfirth lists 10% plus VAT for a single let and 12% plus VAT for an HMO (its fee calculator, checked 17 October 2026).

HMOs cost more to manage for real reasons: one house means several tenancies, a shared-house chat that never stops, more repairs in shared kitchens and bathrooms, the HMO licence, and fire alarm and emergency lighting checks on top of gas and electrical safety.

VAT, who pays, and tax

• VAT. Agents must display and publish their fees, and each amount must be shown “inclusive of any applicable tax” (Consumer Rights Act 2015, section 83). Quotes and proposals still often say “+ VAT”, so check which you’re comparing.
• The landlord pays. Under the Tenant Fees Act 2019 tenants in England can only be asked for the permitted payments, so letting, referencing, inventory and renewal fees can’t be passed on to them. Doing check-ins yourself? Our free landlord inventory template builds the inventory room by room.
• Tax. HMRC lists “letting agent fees and management fees” as an allowable expense against rental income (GOV.UK, working out your rental income), so the after-tax cost is lower than the calculator’s figure.

Renewal fees and the Renters’ Rights Act

Older agency agreements often charge a renewal fee each time a fixed-term tenancy is renewed. In England, the Renters’ Rights Act removed fixed-term assured tenancies: since 1 May 2026 new tenancies are periodic and existing fixed terms became periodic (GOV.UK guide to the Renters’ Rights Act). With no fixed term to renew, the calculator has no renewal line. If your agreement still lists one, ask the agent what it now pays for. Rent reviews remain: a rent increase now goes through a section 13 notice, and our section 13 notice template fills in Form 4A for you. To see what a rise is worth before the agent’s percentage, use the rent increase calculator.

Costs HMO landlords forget

• Turnover. Room lets change hands more often than whole houses, and every move-in is a letting fee, a check-in and a new agreement. Our free tenancy agreement template writes one per room if you do the lettings yourself, and our pro rata rent calculator works out each new tenant’s first part month.
• Bills. If rent is bills-inclusive the agent’s percentage is usually charged on the whole rent, bills included. Our council tax checker gives the 2026/27 bill for any council and band.
• Yield. A fee that looks small against rent can be large against profit. Put the total into our HMO rental yield calculator to see what it does to net yield and cash flow.

What the fee pays for, and the other way to get it done

Most of a management fee pays for hours: answering enquiries, showing rooms, chasing repairs, keeping certificates in date and reconciling rent. Landlords who self-manage save the fee but take on the hours. Bricky Bot sits in between: an AI lettings team that does that work for the landlord, built by an HMO operator, with a person approving every message before it goes out.

If you’re weighing an agent against running the rooms yourself, our guide to HMO management software shows how Bricky Bot handles each of these jobs, and prices are on the pricing section of our homepage. Already using August’s landlord app to self-manage? Read Bricky Bot vs August.
