Customer Reviews & Testimonials

Choosing a plumber or property maintenance company is a matter of trust. You’re inviting someone into your home or business, often at a stressful moment, and you need to feel confident they’ll do the job properly, treat your property with care, and be honest with you throughout.

We believe the best way to earn that trust is to let our customers speak for us. On this page you’ll find genuine feedback from homeowners, landlords, and businesses across London who’ve experienced our service first-hand — covering everything from emergency call-outs to full bathroom installations.

WHAT OUR CUSTOMERS SAY

We’re proud of our reputation, but we know that a company talking about itself only goes so far. What matters is what happens after we leave your property — whether you’d call us again, and whether you’d tell your neighbours about us.

The reviews collected here span the full range of our plumbing and property maintenance services, from urgent repairs to planned installations and ongoing maintenance contracts. We publish them as they are — honest, unedited, and written by people who’ve been in the same position you might be in right now.

REVIEWS BY SERVICE TYPE

We carry out hundreds of jobs across London every year. To help you find feedback most relevant to your situation, here’s a summary of the work our customers most commonly review — along with links to learn more about each service.

Emergency Plumbing Reviews

When something goes seriously wrong — a burst pipe, a major leak, water coming through the ceiling — the quality of a company’s emergency response is what really tests their mettle. Customers who’ve used our emergency plumbing service consistently highlight how quickly we responded, how clearly we explained what was happening, and how we stayed calm when they weren’t.

Emergency plumbing is available 24 hours a day, 7 days a week. Call us directly on +44 7400 265421 or visit our emergency line page.

“I had a burst pipe on a Sunday evening and genuinely didn’t know what to do. Catalyst were on the phone within minutes and at my door within the hour. The engineer was brilliant — explained everything, fixed the problem, and didn’t try to upsell me on things I didn’t need. Couldn’t have asked for more.” — Sarah M., Islington

“Called at 11pm on a weekday with water pouring into my kitchen from the flat above. The engineer arrived in under an hour and isolated the leak without causing any additional damage. Absolute lifesavers.” — James R., Clapham

Leak Detection & Repair Reviews

Hidden leaks are one of the most stressful plumbing issues because you know something is wrong but can’t see it. Our leak detection and repair service uses specialist equipment to locate the source accurately — saving customers from unnecessary damage, disruption, and cost.

“I’d had a slow leak somewhere behind the kitchen wall for weeks. Another company wanted to rip out half the tiles to find it. Catalyst used detection equipment, found it in under an hour, and made a small, targeted repair. The difference in approach was night and day.” — David H., Wandsworth

“Brilliant service. Found a leak under the floor that I’d have never found myself. Quick, clean, and reasonably priced.” — Priya K., Hackney

Blocked Drain & Drainage Reviews

Blocked drains are one of the most common calls we receive, and also one of the areas where poor-quality work causes the most frustration — a drain that’s only partially cleared will block again within days. Our customers who’ve used our drainage services and blocked drain clearance service note that we clear thoroughly rather than just temporarily, and that we explain what caused the problem in the first place.

“Drain in the back garden had been backing up for a few days. Engineer arrived on time, cleared it properly, and showed me on the camera where the root intrusion was happening. Really thorough and professional.” — Mark T., Bromley

“Called about a blocked kitchen drain. They arrived the same day, cleared it, and gave me some tips on avoiding it happening again. Very pleased.” — Caroline F., Finchley

Bathroom Fitting Reviews

A bathroom renovation is one of the most significant projects you can undertake in your home. It involves multiple trades, tight spaces, and a period where you’re without a functioning bathroom — so the experience needs to be managed well from start to finish. Customers who’ve had their bathrooms fitted by Catalyst highlight the quality of the finish, the project management, and the fact that the job was completed on schedule.

“Completely new bathroom from scratch — new layout, new suite, new tiling, the lot. The team were tidy, punctual, and the result is honestly better than I’d imagined. They flagged a potential issue with the existing pipework early on and sorted it without drama. I’d use them again without hesitation.” — Rachel G., Richmond

“Replaced an old avocado bathroom suite in our Victorian terrace. The team dealt with all the quirks of an older property brilliantly. Really pleased with the outcome.” — Tom B., Lewisham

Boiler & Water Heater Service Reviews

Annual boiler and water heater servicing is one of those jobs that’s easy to put off — but our customers who’ve had it done consistently say it’s the sort of thing that gives you real peace of mind, especially heading into winter. Our boiler and water heater service is carried out by Gas Safe registered engineers, and we provide all relevant certificates on completion.

“Had my boiler serviced for the first time in a couple of years. The engineer was efficient, thorough, and pointed out a small issue with the flue that I’d have never noticed — sorted it there and then. Signing up for an annual contract so I don’t forget again.” — Anita W., Chiswick

“Very professional. Explained what they were doing throughout, certificate issued the same day. Would definitely recommend.” — Lee M., Stratford

Landlord & Commercial Reviews

For landlords and commercial clients, reliability and documentation are just as important as the quality of the work itself. You need contractors who understand compliance obligations, communicate promptly, and can service multiple properties consistently. Our commercial plumbing and Annual Maintenance Contract customers often mention these qualities specifically.

“I have four rental properties in South London and managing maintenance used to be a headache. Signing up to Catalyst’s AMC has genuinely changed that — scheduled visits, prompt responses to tenant call-outs, and all the documentation I need for compliance. Highly recommended for other landlords.” — Marcus A., Property Investor, South London

“We use Catalyst for our office building maintenance. Reliable, professional, and they don’t disrupt our working day. Exactly what we needed.” — Operations Manager, Professional Services Firm, City of London

General Repair Reviews

Not every job is a major project or an emergency — sometimes it’s a dripping tap, a toilet that won’t stop running, or water pressure that’s dropped off in the last few months. Our repair services cover all of these, and customers appreciate that we treat smaller jobs with the same care and honesty as larger ones.

“Came out to fix a tap that had been dripping for months. Quick, clean job, sensible price. Will definitely use again for anything else that comes up.” — Helen J., Muswell Hill

“Had low water pressure throughout the house. Engineer diagnosed the cause quickly and sorted it in a single visit. Very happy.” — Yusuf O., Tottenham

WHY CUSTOMER FEEDBACK MATTERS TO US

We ask every customer to leave a review — not because we want to collect numbers, but because it holds us accountable and helps people like you make a better-informed decision.

When something doesn’t go exactly to plan (and in any trades business, occasionally it won’t), we want to know about it so we can put it right. Honest feedback, including critical feedback, helps us improve and stay focused on the things that matter most to our customers.

You can also find us on third-party review platforms, where our reviews are independently verified. We never pay for reviews or manipulate feedback in any way.

THE QUALITIES OUR CUSTOMERS MENTION MOST

Looking across the reviews we’ve received, a few themes come up time and again:

Punctuality — We turn up when we say we will. If something changes, we call ahead. Our customers notice this because, unfortunately, it’s not always the norm in the trades.

Clear communication — Our engineers explain what’s happening in plain English, discuss options where they exist, and don’t proceed without your agreement. Several customers specifically mention being kept in the loop throughout their job.

Honest pricing — We quote before we start and stick to it. Customers who’ve had experiences elsewhere with unexpected add-ons frequently comment on how straightforward our billing is.

Clean, tidy work — We protect your floors, clean up properly before we leave, and treat your home or business with respect.

Qualifications and compliance — Particularly for landlords and commercial clients, the fact that we’re appropriately qualified and provide proper documentation matters enormously. See our Licences & Certifications page for full details.
