From Call-Out to Clause: Decoding a London Carpet-Cleaning Quote Before You Book
You ring three firms on a Tuesday, get three numbers by Thursday, and they don't remotely agree. One says £45. One says £120. One says "from £30" and won't be drawn further. None of them, you suspect, is telling you the whole story. You're not paranoid — you're just reading a quote that hasn't finished being written yet.
Carpet cleaning is one of those trades where the headline figure is more of a opening bid than a final price. That isn't automatically dodgy. Rooms vary wildly, soiling varies wildly, and a company quoting blind over the phone has to protect itself somehow. But there's a difference between a quote with moving parts and a quote built as a trap. Learning to tell them apart is worth twenty minutes of your evening.
"One room" is not a unit of measurement
First thing to pin down: what counts as a room? A box bedroom in a Walthamstow terrace and a through-lounge in a Barnes townhouse are both "one room" under a generous reading, and the difference in floor area could be fivefold. Reputable firms work from a price per square metre, or at least band their rooms — small, standard, large — and will tell you which band your space falls into.
Ask directly: is this priced by area or by room, and what area does the price assume? If the answer is vague, expect the estimator to reach for a tape measure on arrival and for the price to move accordingly. That's not necessarily sharp practice, but you should know it's coming.
Worth remembering too: stairs, landings and hallways are usually priced separately, per flight or per step. A "three rooms for £99" offer that quietly excludes the staircase everyone actually walks on is not a bargain, it's a floor plan.
The minimum call-out, and why small jobs cost more per metre
Most London operators have a minimum job value — broadly somewhere between £80 and £130 in 2026 money, depending on the firm and how far into zone 1 they're travelling. Below that threshold, the fuel, the parking permit, the setup and the two hours of a technician's day simply don't add up.
This is legitimate and worth respecting. What isn't legitimate is a minimum call-out that's only revealed after you've booked. Ask upfront: what's the smallest job you'll take, and is there a call-out charge on top?
VAT: the line that changes the arithmetic
A £60-per-room quote plus VAT is £72. Over four rooms, that's an extra £48 you hadn't budgeted for — roughly the cost of a decent stain treatment. Some firms advertise excluding VAT because their commercial clients expect it; some do it because it makes the website look cheaper.
Just ask whether the figure is inclusive. Any straight answer is a good sign. A defensive one tells you plenty.
The add-on ladder
Here's where quotes really sprout legs. Typical extras you'll see quoted separately:
- Pre-treatment for heavy soiling — reasonable, especially on a hallway or a rental that's had a hard year.
- Stain treatment — often priced per stain, sometimes capped. Ask what happens if the stain doesn't come out.
- Protector or stain guard — a genuine product, genuinely optional. Say no once and see whether the price holds.
- Deodorising or sanitising — useful after pets, often bundled anyway. Worth knowing which.
- Moving furniture — usually included for light items, charged for beds and sofas. Clarify before the day.
- Upholstery, rugs, mattresses — separate services. Fine, as long as they're not quietly assumed.
None of these are conspiracies on their own. The question is whether the quote you were given reflects the job you described. If you mentioned a wine stain on the phone and the estimate has no stain line, either it's included — ask — or it's coming.
What a fair 2026 London estimate looks like
As a rough shape, not a rule: a mid-market London firm in 2026 tends to sit somewhere in the £40–£65 band per standard room for hot-water extraction, with the price per room falling as the job gets bigger. Hallways, stairs and landings add on. A minimum call-out applies. VAT may or may not be inside the number.
A trustworthy estimate, in our experience, has four characteristics:
- It's itemised — rooms, extras, VAT, total, all visible.
- It's conditional where it needs to be — "subject to inspection" is honest, not evasive, provided the conditions are stated.
- It's in writing before the visit, even if it's a text message.
- It matches the conversation you actually had about pets, stains and that patch by the door.
Questions worth asking before you book
- Is this price inclusive of VAT?
- How do you define a room, and does that include the stairs?
- What's included in the base price — pre-vacuum, pre-spray, furniture moving?
- If a stain doesn't lift, what happens? Do I pay for the attempt?
- Is there a call-out charge, a parking charge, or anything else on top?
- What's your cancellation policy if I need to move the date?
Six questions, five minutes. Any firm that finds them tiresome is telling you something useful.
The shape of a price that's built to climb
Be wary of a quote that is dramatically below everyone else's, delivered with no questions asked. Cleaning a carpet properly takes time, water, heat, chemistry and a van that costs a fortune to run in this city. A number that ignores all of that will usually be recovered on the day — through a "heavier soiling" surcharge, a mandatory protector, a per-stain fee, or a sudden discovery that the price only covered the traffic areas.
Equally, watch for the quote that arrives without a written breakdown and the firm that won't put a figure in a message. Verbal-only pricing is a one-way door.
Get it in writing, then relax
A good estimate is boring. It lists what will happen, what it costs, and what happens if the job turns out to be worse than described. It doesn't need to be dramatic or clever — it needs to be clear enough that neither of you is improvising on the doorstep.
If you're comparing quotes across London and something feels slippery, it usually is. Ask the question. The good firms will thank you for it.
