Online vs high-street letting agents: the real cost

Part of our Compare Letting Agents
Online and high-street letting agents charge in two different shapes: a fixed fee, usually paid upfront, or a percentage of your rent, usually paid once the property is let. Neither is automatically cheaper. Your real cost is decided by what the fee includes, who does the work when a tenancy goes wrong, and whether you still pay if the property never lets.
Most comparisons of online and high-street letting agents come down to a single headline number, and that number is almost always misleading. A fixed fee of a few hundred pounds looks like an obvious win against a percentage of rent for a year. It stops looking obvious the first time a tenant stops paying and you find out that chasing arrears was never in the package.
This guide sets out the difference in structure rather than quoting national averages, because averages hide the thing that matters: what each agent does for the money. For fee figures on agents near you, go to the agents’ own published fee lists, which they are required to make available, or run a comparison at AgentCheck.
The two fee shapes
Online letting agents typically sell packages. You pay a set amount for a defined list of tasks, often before any work starts, and anything outside the list is a paid add-on. Some run a monthly subscription instead of a one-off charge, which behaves a bit like a percentage fee but does not move when your rent moves.
High-street agents usually charge a percentage. For tenant-find work that is a share of the annual rent, billed once the tenancy starts. For management it is a share of each month’s rent, deducted before your money is passed on. Add VAT where the agent is VAT-registered, and read whether the quoted rate already includes it. A rate quoted plus VAT costs a fifth more than the same number quoted inclusive.
There is a third shape worth naming: the hybrid. A fixed marketing fee to get the property let, then a smaller percentage for ongoing management. It is common and it can be good value, but it doubles the number of price lines you need to check.
What the fee actually buys
The useful comparison is task by task. Take an agent’s quote, list every job below, and mark each one as included, extra, or yours.
| Job | Why it moves your cost |
|---|---|
| Accompanied viewings | Cheap packages often expect you to do them. If you live an hour away, that is fuel and evenings. |
| Referencing and affordability checks | Often billed per applicant, and in England the cost cannot be passed to the tenant. A property with several applicants can quietly cost you more. |
| Inventory, check-in and check-out | The Tenant Fees Act 2019 means you pay for these, not the tenant. Check whether they sit inside the package or outside it. |
| Deposit registration and prescribed information | Getting this wrong is expensive. Check who is legally responsible, not just who presses the button. |
| Rent collection and arrears chasing | Some packages pass rent through but stop at the first missed payment. |
| Repairs coordination | Ask whether contractor callouts carry a markup or an arrangement fee. |
| Inspections | How many a year, and are they charged separately? |
| End of tenancy and deposit disputes | Preparing an adjudication case takes hours. Find out whose hours. |
| Serving notices and possession paperwork | Almost always an extra, at both types of agent, and it matters more now section 21 has gone. |
Once that grid is filled in for two or three agents, the cheaper option usually names itself. Our guide to fully managed versus let-only covers where the sensible dividing line sits.
Upfront or on-let: where the risk sits
This is the difference people notice least and regret most. If you pay upfront, you have bought an attempt to let your property. If the advert underperforms, the price was wrong, or the photographs are poor, you have already paid. If you pay on let, the agent carries that risk with you and has a direct reason to get it right quickly.
That does not make upfront pricing bad. For a well-priced property in an area with strong demand, paying once and keeping the rest of your rent can work out well, and plenty of landlords do exactly that. Just be honest about which of you is carrying the risk of a slow let, because you are paying for that either way.
What the Renters’ Rights Act changed about the maths
Since 1 May 2026 the rules underneath every tenancy have changed, and they change the value of management. Assured shorthold tenancies and fixed terms have gone. All tenancies are periodic. Section 21 no-fault eviction is abolished, so ending a tenancy means establishing a section 8 ground and getting the paperwork right. Tenants can leave by giving at least two months’ notice at any point, with the notice expiring at the end of a rental period.
Rent increases now run through one route only: a section 13 notice on Form 4A, at least two months before the increase takes effect, and no more than once every twelve months. If the tenant thinks the figure is above market rent they can refer it to the First-tier Tribunal, which cannot set a rent higher than the one you proposed. Rent-review clauses in the tenancy no longer do the job.
The practical effect is that the administrative side of letting got heavier and the cost of a mistake got higher. If you are choosing a stripped-back package, you are choosing to do that work yourself. That is a reasonable choice for a confident landlord with one local property. It is a worse choice if you are new to letting or two hundred miles away.
Marketing rules apply to both types of agent
A few rules apply regardless of who lists the property, and a cheap package does not excuse them:
- The advertised rent is now a ceiling. The proposed rent must be stated when the property is advertised or offered, and neither you nor your agent may ask for, encourage or accept an offer above it. Local housing authorities enforce this, with civil penalties of up to £7,000 for a first breach and up to £40,000 for repeat breaches.
- A valid EPC rating must appear in the listing under the Energy Performance of Buildings Regulations 2012, unless the building is exempt.
- Discriminating against applicants because they receive benefits or have children is unlawful, in adverts and in screening criteria.
These duties fall on you as well as the agent, so a package that leaves the advert wording to you leaves the liability there too.
Check the fee page before you call
Section 83 of the Consumer Rights Act 2015 requires letting agents to publicise their fees, on their website and in their offices, with each fee described well enough that you can tell what work it covers. The same duty covers whether they belong to a client money protection scheme and which redress scheme they are a member of. Trading standards can impose a financial penalty for a breach.
Treat a vague or missing fee page as data. An agent who will not put their charges in writing before you engage them is unlikely to get clearer once your money is in their client account.
How to compare properly
- Get every quote on the same basis: inclusive of VAT, over the same period, on your actual rent.
- Model a bad year, not a good one. One month of arrears, one deposit dispute, one boiler replacement.
- Ask what happens if the property does not let in eight weeks, and who pays for what then.
- Ask who your named contact is and how quickly they answer.
- Read the notice period in the agency agreement before you sign, not after.
If you want the detail on how each model works in practice, read our complete guide to online letting agents and the breakdown of letting agent fees. And if you already know the fee is too high, there are sensible ways to bring it down without dropping the service you need.
The right answer is not a type of agent. It is the agent whose fee structure matches how much of this work you genuinely want to do yourself.
