Carpet cleaning is not a regulated trade. There is no licence, no compulsory training and no qualification anyone has to hold before turning up at your door with a machine. That does not mean the industry is full of chancers, but it does mean the responsibility for telling them apart lands on you.
We are obviously not a neutral party here. What follows is still the list we would give a family member ringing round in a town where we do not work, and one or two of the answers are ones plenty of firms would rather you did not ask for.
“How long will it take to dry?”
The most revealing question you can ask, and it costs nothing. Drying time is a direct proxy for extraction power. Water going in is easy; getting it back out is what separates professional equipment from a hired machine. A long drying time is also the root cause of most complaints afterwards, from musty smells to stains returning.
Two to four hours to touch-dry, around six to be fully dry.
"A day or so", or a vague answer, or irritation at the question.
“Are you insured, and can I see the certificate?”
Public liability covers damage to your property. Carpet cleaning involves water, chemicals and moving furniture in someone else's home, and things occasionally go wrong. Plenty of one-van operations carry no cover at all, and you only discover it at the worst moment.
Yes, sent over without any fuss.
Hesitation, or "we have never needed it".
“What method do you use, and why that one for my carpet?”
You are not testing whether they pick your preferred method. You are testing whether they can explain a choice. Someone who says hot water extraction because of pets and embedded soil, or low moisture because you need the room back tonight, is thinking about the job.
A specific method with a reason attached to your situation.
A method named with no reasoning, or dismissing every alternative.
“Is that a fixed price or an estimate?”
Per-room pricing quoted before anyone has seen the rooms is a starting figure. The gap between it and the final bill usually appears as stain treatment, furniture moving or protector, added once the van is already outside and you feel committed.
Fixed, once they have seen photographs or the rooms.
"From £X per room", with the real number arriving on the day.
“Does the price include moving furniture and treating stains?”
These are the two most common add-ons. Most cleaners move sofas and beds but not electronics or heavy wardrobes. Stain treatment should generally be part of a deep clean rather than a separate line. Establish it in writing beforehand.
Clear about what is moved and what is included.
Both listed as extras discovered on arrival.
“Will you tell me if something is not going to come out?”
The single best trust signal in this list. Bleach marks and some dye damage change the fibre colour itself rather than sitting on top of it, so there is nothing to lift. Anyone who guarantees every stain either does not know that or is prepared to tell you something untrue to secure the booking.
Yes, and an explanation of what tends to be permanent.
"Everything comes out."
“How long are you allowing for the job?”
This converts a price into labour, which is the only fair way to compare two quotes. A thorough job on three rooms is not a forty-minute visit. If the time allowed looks short, that is where the price difference has come from.
A realistic figure that scales with the rooms involved.
A whole house in an hour.
“What happens if I am not happy?”
Specificity is everything here. A named window and a defined remedy is worth something. A slogan is not. Under the Consumer Rights Act, work must be carried out with reasonable care and skill regardless of what any guarantee says, but a clear policy saves you having to rely on that.
A commitment to return within a set period and re-clean.
"Satisfaction guaranteed", with nothing behind it.
What trade body membership does and does not tell you
NCCA membership means somebody has completed training, holds insurance and can be complained to. WoolSafe approval means products and technicians have been assessed as safe for wool. IICRC certification means an individual technician has been trained to an international standard.
None of these guarantee a good result on the day, and there are excellent cleaners who have never joined anything. What membership gives you is a floor rather than a ceiling: evidence of training, and somewhere to go if things go badly. On a wool or antique rug, we would weight it more heavily, because the cost of an untrained decision is much higher.
Reading reviews usefully
- Look for specifics. Reviews naming the room, the stain and the drying time were written by real customers. Generic praise could be about anything.
- Read the mediocre ones. The three-star reviews tell you more than either extreme, because they usually describe exactly where expectations and reality parted.
- Check the responses. How a company answers a complaint tells you what will happen if you have one.
- Watch the dates. Twenty reviews in one week, then nothing for a year, is a pattern worth noticing.
- Prefer local ones. Reviews from your area suggest a business that actually works there rather than a national lead-generation site subcontracting the job on.
Warning signs worth walking away from
- Cash only, no paperwork. No receipt means no record if there is a dispute, and it is a problem in itself if the clean is tied to a tenancy deposit.
- Pressure to decide immediately. A price only available if you book on the call is a sales technique, not a discount.
- A price that changes on arrival without the scope changing.
- No address anywhere on the website. Not always sinister, but you want to know where a business actually is.
- Guarantees on everything. Confidence is good. Claiming every stain in every carpet comes out is not confidence.
Before you ring anyone
Worth asking whether you need this at all. Fresh spills often come out at home, and if the carpet was cleaned recently it may not be due. Our guides to how often carpets need cleaning and removing common stains will tell you fairly quickly whether a call is warranted.
If it is, understanding the difference between the methods means question three gets a much more interesting answer, because you will know whether the reasoning holds up.
Where this advice comes from
We work to the standards below, and we have pointed you to them directly so you can check anything here yourself rather than taking our word for it.
- National Carpet Cleaners Association (NCCA) — UK trade body with a searchable member directory. Members complete training, hold insurance, and are subject to a complaints procedure.
- WoolSafe — Certification for wool-safe products and approved service providers. Worth checking specifically if your carpet or rug is wool.
- IICRC — International certification body behind the S100 carpet cleaning standard. Technicians can be certified individually.
- Citizens Advice — problems with services — Your rights under the Consumer Rights Act if work is not carried out with reasonable care and skill.
What we would actually buy
Nothing here is really a product. What protects you when hiring anyone is a record of what things looked like beforehand.
Photographs of any stains and problem areas
Send these with your enquiry. It gets you a more accurate quote, and it gives you a dated record of the condition beforehand, which matters if anything goes wrong.
A copy of the public liability certificate
Any legitimate operator will send it without hesitating. If the question causes friction, that is the useful information.
Clear small items and breakables yourself
It saves time you are paying for and removes any argument about who moved what. Most cleaners move sofas and beds; ornaments and electronics are usually yours to shift.
Two household fans
Whatever the cleaner does, airflow across the pile shortens drying and reduces the chance of a musty smell. Cheap, and entirely within your control.
Nobody pays us to list these and there are no affiliate links on this page. They are simply what we have found works, and in several cases the cheapest option genuinely is the best one. Whatever you use, patch-test it somewhere hidden first.
The Carpetix Team
We are a carpet, upholstery and rug cleaning team based in Leytonstone, East London. We write these guides from what we run into on actual jobs, which is why you will find us telling you when to leave something alone or handle it yourself rather than call anyone out. If a guide here saves you a call, it has done its job.
