Letting agent fees are usually the single biggest recurring cost of running a buy-to-let, and they are also the least standardised. Two agents on the same high street can quote figures that differ by thousands of pounds a year for what sounds like the same service. This guide sets out the three service levels, typical 2026 fee ranges, the extras that creep onto invoices, and the two things that catch landlords out most often: VAT and the drag on net yield.
One caveat before the numbers. Fees vary by region, property and agent, so everything below is a typical market range, not a quote. Always get the full fee schedule in writing before you sign terms.
The three service levels and what they typically cost
Tenant-find only
The agent markets the property, runs viewings, references the tenant and sets up the tenancy, then hands the relationship back to you. You typically pay a one-off fee of around one to four weeks' rent, or a fixed fee that often lands between the low hundreds and around a thousand pounds. It is the cheapest option per tenancy, but you pay it again every time the property re-lets, so frequent turnover makes it more expensive than it looks.
Rent collection
The agent finds the tenant and then collects the rent each month, chases arrears and passes the money on. This usually costs roughly 8-10% of the monthly rent, often with a reduced set-up fee on top. You still handle repairs, inspections and the day-to-day relationship yourself.
Full management
The agent runs everything: marketing, referencing, rent collection, repairs coordination, inspections, renewals and the paperwork in between. Typical fees sit roughly in the 10-15% of monthly rent range, with London agents commonly at the top of that band or above it. It is the level most remote or time-poor landlords choose, and the one that does the most damage to net yield if you never question the rate.
What is included, and what costs extra
The headline percentage rarely covers everything. Fee schedules differ, but a common pattern looks like this:
- Usually included in full management: marketing and viewings, tenant referencing, rent collection and arrears chasing, coordinating repairs (the works themselves are billed to you at cost), and periodic inspections.
- Often charged extra: the inventory and check-in report, the checkout report at the end of the tenancy, tenancy renewal or re-signing fees, deposit protection administration, arranging an EPC or gas safety certificate (the certificate cost plus sometimes an arrangement fee), serving notices, and court attendance if things go wrong.
The extras matter because they arrive per event, not per month. A renewal fee here and an inventory there can quietly add several hundred pounds to a year that already carries a 12% management charge. Get the full tariff, including end-of-tenancy charges, before comparing agents on the headline rate.
The Tenant Fees Act 2019: why the bill moved to landlords
Until 2019, agents charged tenants for referencing, inventories, check-ins and admin. The Tenant Fees Act 2019 ended that in England for tenancies signed or renewed on or after 1 June 2019. Under the Act, agents and landlords can only take a short list of permitted payments from tenants: rent, a refundable tenancy deposit capped at five weeks' rent where the annual rent is under £50,000, a holding deposit capped at one week's rent, a capped £50 charge for varying the tenancy, and limited default fees such as late rent or lost keys. Wales has a similar ban under its own legislation.
The commercial effect was predictable: costs the tenant used to pay did not disappear, they moved into the landlord's fee schedule. Referencing, inventory and set-up charges now sit on your side of the ledger, which is a large part of why landlord tariffs grew after 2019. It is not a reason to avoid agents, but it is a reason to read the landlord tariff line by line, because the whole cost of the tenancy set-up now lives there.
The VAT gotcha: quoted fees often exclude 20%
Here is the classic trap. An agent quotes "12% management" and you budget 12%. But letting agent fees carry VAT at 20%, and plenty of agents quote exclusive of it. A 12% + VAT fee is really 14.4% of rent.
On a £1,000 a month rent, that is the difference between £120 and £144 a month: £288 a year, every year, on a single property. Across a five-property portfolio at similar rents, the "small print" VAT is worth roughly £1,400 a year. So convert every quote to a VAT-inclusive percentage before comparing agents, and treat a fee schedule that hides the VAT position as a warning sign.
What management does to your net yield
Fees are not an abstraction, they are a direct deduction from every month's rent. Take the same example we use in our buy-to-let running costs post: a £200,000 house let at £1,000 a month, a 6% gross yield. Full management at 12% including VAT costs £1,440 a year, which on its own drags net yield down by about 0.7 percentage points before you touch voids, repairs or insurance. At 14.4% (the 12% + VAT quote), the annual cost is £1,728 and the drag is closer to 0.9 points.
Self-managing the same property saves that £120-£144 a month, but only if your time and travel are genuinely free. The honest way to decide is to run both versions of the deal: put the VAT-inclusive fee into the BTL cashflow calculator and see the monthly cash difference, then sanity-check the headline return with the rental yield calculator. A percentage feels small; the same number as pounds per month reads very differently.
Negotiating, and when self-managing makes sense
Fees are more negotiable than most landlords assume. Multiple properties with one agent, a long-term instruction, or a tenant already in place all justify asking for a lower rate, and a fixed monthly fee can beat a percentage on higher rents. At minimum, ask for renewal fees to be reduced or dropped, since a renewal costs the agent very little.
Self-managing suits landlords who live near the property, have time, and enjoy the work. But be clear about what you take on: deposit protection within 30 days and the prescribed information, gas safety, EICR and EPC duties, smoke and carbon monoxide alarms, right to rent checks, correct notices, and keeping up with tenancy law as it changes. Miss a compliance step and the saving evaporates fast. If you go this route, use our compliance deadline checker so the statutory dates never slip.
Either way, the discipline is the same: know the full VAT-inclusive cost of the service level you choose, and put it in your numbers before you buy, not after the first invoice arrives.
