The expensive surprises in a maintenance contract almost never hide in the price. They hide in the clauses around it, in the rules you skimmed before you signed. Here are the five places to check before you do, and exactly where we stand on each.
In a hurry? The bottom line:
- The hidden cost in an AMC is rarely the charge itself. It’s a rule, written to be skimmed, that you only meet once it’s on an invoice.
- Five clauses are where surprises live: how exclusions are defined, whether the property is surveyed before cover starts, the cancellation term, auto-renewal, and what reaches your invoice without your approval.
- The test of a provider isn’t whether these terms exist. It’s whether they can tell you all five answers before you pay.
- Our own positions, named not buried: defined exclusions you can read in advance, a pre-contract survey that flags pre-existing faults in writing within 48 hours, a cancellation term with a worked AED example, a 30-day renewal notice with a 45-day reminder, and no part charged without your written approval first.
Before a recent AC job, a customer asked us a question that sits underneath almost every maintenance contract ever signed. He wanted to know, before booking anything, whether the visit would fix his problem “without any additional charges.”
“so if u r coming issue will be fixed without any additional charges right?”
We told him plainly. The service rate is the service rate, and if parts are needed to resolve the issue, those are billed separately. He knew the rule before he agreed to anything, which is the only point at which knowing it actually helps you.
That small exchange is the whole subject of this post, though it goes well beyond parts. The hidden cost in a maintenance contract is almost never the charge itself. A part costs what a part costs, and so does a callout, a renewal, or a cancellation.
What stings is finding out about any of them after you have signed, when the rule that produced the charge was sitting in a clause you skimmed, written to be skimmed. The cost was never hidden. The rule was.
So this is not a list of things AMCs charge you for. We already published our prices in the cost guide and our coverage scope in the what-is-covered guide, both line by line.
This is the layer underneath: the five places in an AMC contract where surprises hide. In what is excluded, in faults later called pre-existing, in how you exit, in how it renews, and in what reaches your invoice without your say-so.
Vague exclusion lists
Every AMC excludes some things: structural work, full renovations, damage from misuse. A clear contract lists those plainly. The trap is the exclusion list written vaguely enough that the provider gets to decide, after the fact, what falls inside it.
Phrases like “general maintenance as required” or “major works excluded,” with no definition of what major means, are not really scope. They are room to argue, and you are the one who loses the argument once the work is already done.
The tell is whether the boundary is defined in advance or decided on the day. Is “emergency” a written definition you can read before you sign, or a judgment the provider makes when you call? Is “out of scope” a list you can point to, or a feeling that arrives with the invoice?
A defined exclusion names the thing. Ours do: underground or concealed pipework, structural repairs and wall demolition, swimming pool systems, and specialised systems outside an MEP licence such as IT, smart-home, and AV equipment.
The pipework line is the one people miss most. Reaching a leak buried in a wall or under a floor means opening up the structure, which is a different job from the routine plumbing most people picture.
You may not love that those sit outside the fee, but you can read them and price them before you sign. A vague exclusion does the opposite, leaving the provider to draw the line once the work is underway.
Ours are written down. What counts as an emergency, what counts as an in-scope repair versus a billable addition, where covered labour ends and parts begin: all of it is set out in the what-is-covered guide and the contract itself, not decided in the moment.
You should be able to read the line before you find yourself on the wrong side of it.
Faults blamed on “pre-existing” conditions
This one only surfaces months after you sign. Something fails, you call it in, and the provider inspects it and tells you the fault was already there when the contract started, so it falls outside cover.
You are now paying full price for a repair, at the worst possible moment, on a judgment made after the fact.
The tell is whether the provider looks at the property before the contract starts or only after something breaks. A company that inspects up front has no room to claim surprise later. One that skips it has every incentive to find a pre-existing fault the day you need them most.
We run a pre-contract survey within 10 days of signing and put the findings in writing within 48 hours. If it turns up a pre-existing fault, we say so plainly, and that system stays outside cover until the repair is done.
That part is worth being straight about: a survey finding can mean a repair bill before you are fully covered. The difference is that you learn it in the first week, with a written quote you can weigh, rather than at 2am during a breakdown when you have no leverage.
What you lose if you cancel early
This is the one providers are quietest about, which is exactly why it belongs in a post like this. What happens to your money if you cancel partway through the year?
Some contracts say nothing at all, which means you find out the terms during the argument rather than before it. Others are written as fully non-refundable, so the provider keeps everything regardless of how little of the year you used. Both are worth catching before you sign, not after.
The tell is simply whether the contract tells you anything at all. A cancellation term you can read up front, even one you do not love, is a better sign than silence.
Here is ours, named rather than buried. If you cancel partway through, we deduct a 25% administration and mobilisation retainer from the annual value, then refund 75% of whatever is left of the unused period, worked out month by month from the date you give notice.
The contract spells it out with a worked example: cancel four months into a 12-month AED 6,000 contract, and the eight unused months are worth AED 4,000, of which 75% comes back to you, so AED 3,000.
You may think that split is fair or you may not. Either way you can read it, and the worked example, before you sign. A provider willing to put its cancellation terms in plain numbers is telling you something useful about every other clause too.
Auto-renewal that rolls over silently
Most AMC contracts renew themselves, and that on its own is normal rather than sinister. The trap is the version that renews silently, on a narrow cancellation window, at a price you never re-approved.
You signed last March, you forgot the date, and the only signal that a new year started is the invoice. By the time you notice, the notice window has closed.
The tell is whether renewal is treated as a confirmation or a default. A contract that auto-renews is fine if the provider still checks in with you before the new term starts. One that auto-renews and counts on you not noticing is the one to be wary of.
Our own contract names auto-renewal. We keep the clause because it avoids a gap in cover for the customers who do want to roll straight on into another year.
What sits around it is the part that matters: you can cancel renewal with 30 days written notice before the anniversary, and we send a reminder with any updated pricing 45 days before the term ends, so the date never arrives unannounced. The clause exists; the silence does not.
Parts put on your invoice without your yes
Nearly every AMC bills parts separately from the labour. That is standard, and we do it too. The ambiguity that bites is when “parts billed separately” comes with no rule about who approves the spend, and when.
It means the provider can order a part, fit it, and put it on your invoice without ever asking you first. The first you hear of the number is when you are handed it and asked to pay.
The tell here is simple: does anything reach your invoice without your say-so. Some contracts set a threshold, approval needed only above a certain figure, which still leaves everything under it landing on the bill unannounced. The cleaner answer is no threshold at all, where every chargeable part is approved before it is ordered.
That is how we do it. No part goes on your invoice without your written approval first, however small the cost, and a reply on WhatsApp is all it takes.
The only thing you are never asked to approve is the minor consumables on Platinum, the everyday bits like Teflon tape, anti-slime sachets, drain tabs and cable ties under AED 40, because those are free and never reach the bill at all.
The same logic covers emergency labour, only more so. Our emergency callout labour is fully covered, however long the work takes and however many follow-up visits it needs. There is no meter that starts after the first hour, and no charge waiting on the second visit.
That matters because some contracts may promise unlimited emergency callouts, then leave room to restart an hourly charge once the technician returns for a follow-up. Worth checking, because unlimited callouts and a running meter are not the same promise.
The full picture of what sits outside the fee is in the cost guide, so we will not rebuild it here. The point here is narrower. Ask any provider what reaches your invoice without your sign-off, and be wary of one that cannot give a clean answer.
The one question to ask before signing
Every one of these shares the same flaw. The trap is never the term itself, but the vagueness left around it.
A provider worth signing with can tell you all five answers before you pay. One you should be wary of will tell you after, once the answer is printed on an invoice and your leverage to argue it is gone.
So the practical move before you sign is short. Ask for those five answers in writing. How are exclusions defined, is the property surveyed before cover starts, what happens if I cancel, where does renewal stand, and what reaches your invoice without your sign-off.
A good provider will already have them ready.
If you are weighing up an AMC right now and want a second pair of eyes on the one in front of you, send it over. We will tell you where its five answers sit, even when the contract is not ours.
Frequently asked questions
What are the most common hidden costs in a Dubai AMC contract?
The recurring ones are out-of-scope work the contract never clearly defined, faults a provider later calls pre-existing, a cancellation deduction you only discover when you try to leave, and parts put on the invoice without your approval. None are unusual on their own. The problem is a contract that leaves the rule around them vague enough to surprise you later.
Can a maintenance company refuse to cover a fault by calling it pre-existing?
They can if the contract never established the property’s condition at the start, which is why a pre-contract survey matters. Without one, a provider can decide after a breakdown that a fault was pre-existing and bill you at full price. We survey within 10 days of signing and report any pre-existing faults in writing within 48 hours, so the line between covered and not is drawn before you need us, not during the emergency.
Can I get a refund if I cancel an AMC partway through?
It depends entirely on the contract, which is why you should read the cancellation term before signing. Ours deducts a 25% administration and mobilisation retainer, then refunds 75% of the unused remaining period, calculated monthly. As a worked example, cancelling four months into a 12-month AED 6,000 contract returns AED 3,000. The figure matters less than the fact that it’s stated up front.
Does an AMC automatically renew in Dubai?
Many do, including ours. The risk isn’t the auto-renewal clause on its own; it’s a renewal that happens silently at a price you never re-approved, on a notice window you’ve already missed. Ours can be cancelled with 30 days written notice before the anniversary, and we send a reminder with any updated pricing 45 days before the term ends.
Are AMC parts charges normal, or a sign of a bad contract?
Charging for parts separately from labour is standard across Dubai AMCs, and we do it too. What separates a fair contract from a risky one is whether anything reaches your invoice without your approval. We approve every chargeable part with you before it’s ordered, however small, with only the under-AED-40 consumables on Platinum excepted because those are free. A contract that lets parts land on the bill unannounced is the warning sign.
Does emergency labour cost extra on an AMC?
It depends on the contract, so it’s worth checking. Some contracts may cover the first emergency callout but leave room to start an hourly charge when the technician returns for a follow-up visit. Our emergency callout labour is fully covered, however long the work takes and however many visits it needs to finish. Spare parts are still approved and billed separately, but the labour itself never runs a meter.
How do I check an AMC contract for hidden costs before signing?
Ask for five answers in writing: how exclusions are defined, whether the property is surveyed before cover starts, what happens if you cancel, how renewal works, and what reaches your invoice without your sign-off. A provider who has these ready wrote the contract to be read. One who answers vaguely is leaving room to surprise you later. You’re welcome to send us a contract you’re comparing, even if it isn’t ours.
