Finding a good cleaning company in London isn’t as simple as clicking the first Google result and hoping for the best. The city’s packed with options—some excellent, some average, and a few you’d rather not let through the front door.

Whether it’s for your home, your office, or a property you manage, the right cleaning service can make a huge difference. But the wrong one? That usually ends in frustration, wasted time, or a space that somehow looks clean but doesn’t feel it.

It’s not just about price or how many stars they’ve got online. Choosing a cleaning company you can actually trust means asking the right questions up front. Not just “do you have availability?” but the sort of questions that get to the heart of how they operate, how they treat their staff, and whether they’re genuinely suited to your needs.

Here are seven questions worth asking before you hand over your keys or commit to a regular service.

What Services Do You Actually Provide—and What’s Included?

It might seem obvious, but not all companies define “cleaning” the same way. Some include windows, ovens, inside cupboards, or deep carpet cleans in their standard packages. Others charge extra—or don’t offer them at all.

If you’re looking for a regular domestic clean, ask exactly what’s included. Will they change the bed linen? Do they dust skirting boards or just vacuum around them? Are bathroom tiles scrubbed or just wiped?

For office or commercial spaces, ask about frequency, equipment provided, and whether they clean during or outside business hours.

A good company will give you a clear, itemised breakdown of what you’re paying for. If they’re vague or avoid the question, that’s a red flag.

Are Your Cleaners Employed Directly or Self-Employed?

This one matters more than most people realise. Cleaners who are directly employed tend to be better trained, better supported, and more consistent. They usually have insurance, sick pay, and some level of supervision or feedback from the company.

If a company relies solely on freelancers or gig-style workers, quality can be hit and miss. You might get someone brilliant one week and someone completely different (with different standards) the next.

That’s not to say all self-employed cleaners are unreliable—far from it. But a reputable cleaning company should be transparent about who they’re sending, how they’re hired, and what kind of accountability exists.

Do You Bring Your Own Equipment and Eco Products?

Some companies bring everything—products, cloths, vacuums, even gloves. Others expect you to provide the lot. And in between, there’s a sliding scale of options.

If you don’t want your cupboards full of half-used sprays and disposable sponges, it’s worth asking if they bring eco-friendly, refillable, or low-waste products as standard.

For allergy-prone households or scent-sensitive offices, you’ll want to know exactly what’s being used. Ask whether they offer fragrance-free, biodegradable, or cruelty-free options.

A good cleaning company should be able to match the products to your preferences, not just use whatever’s cheapest in bulk.

Are You Fully Insured—and What Does That Cover?

This is a big one. If something breaks, goes missing, or someone gets injured on your property, you need to know where you stand.

Every reputable cleaning company should carry both public liability insurance and employer’s liability cover. That means if there’s accidental damage or someone gets hurt, you’re not left sorting it out alone.

Ask to see proof of insurance. A professional company won’t hesitate. If they sidestep the question or tell you “it’s never been an issue,” walk away. It only needs to be an issue once.

Can You Provide References or Real Reviews from London Clients?

Online reviews are helpful—but curated testimonials on a website only tell part of the story.

Ask if they can put you in touch with long-term clients, ideally based in your area. Someone who’s used the company regularly will be able to tell you about reliability, consistency, and how the team handles feedback or last-minute changes.

If a company has nothing but five-star reviews and can’t provide a real-life reference, it might be worth digging deeper. Look for patterns in their online feedback—mention of the same cleaner turning up regularly is usually a good sign.

What Happens If I’m Not Happy with the Clean?

Even the best cleaners miss a spot sometimes. The question is—what happens next?

A reliable company should have a clear process for feedback and corrections. Will they send someone back? Offer a discount? Log the issue and prevent it happening again?

You want to know that you won’t be ignored or blamed if something isn’t right. Cleaners are human. It’s how the company handles mistakes that sets them apart.

Do You Offer Flexibility Without Locking Me Into a Long Contract?

Life in London changes fast. Routines shift. Work patterns vary. Maybe you’re in the office three days this week, five next. Maybe your flatmate’s away, or your tenant’s just moved out.

A good cleaning company should offer enough flexibility to accommodate that. Whether it’s pausing service, rescheduling visits, or adjusting how much time is needed, they should work with you, not tie you into an 18-month contract with no breathing room.

Ask about cancellation terms, minimum bookings, and whether they’re happy to adjust plans if things change. The best companies know that flexibility keeps clients loyal longer than rigid contracts ever will.

What Else to Watch For

Sometimes, it’s not about the answers—they’re all saying the right things—it’s about how they say them.

Did they get back to you quickly?
Were they friendly but professional?
Did they send a clear quote without you chasing them?

A company that’s well-organised before the first clean is more likely to stay that way afterwards.

And while price matters, the cheapest quote isn’t always the best deal. If a company undercuts everyone else by a mile, ask how they’re paying their staff and what corners are being cut.

FAQs

How much should I expect to pay for a cleaner in London?
Rates vary, but a quality domestic cleaner usually costs £15–£20 per hour. Office cleaning may cost more depending on size, frequency, and services included.

Is it okay to leave cleaners in the property if I’m out?
Yes, if you trust the company and they’ve got proper vetting in place. Ask about key handling, secure storage, and background checks.

What’s the difference between a cleaner and a cleaning company?
A solo cleaner works independently, often with limited backup. A company provides cover, consistent service, insurance, and accountability—ideal for regular or large-scale cleans.
