 Trustindex verifies that the original source of the review is Google. Absolutely brilliant from start to finish. Put a new boiler in a property one day after diagnosing a fault. I didn’t have to worry about one thing - no faffing, just a price given and by the next day it was complete. Armond, John and Claudia were very active throughout the process and offered me free advice to start. I’m always dubious about going with contractors you find on Google but after so many bad experiences - so refreshing for it work out like you always feel it should.

 Trustindex verifies that the original source of the review is Yell. Armand arrived the same morning as I called, keeping me informed as to his expected arrival time. He was very efficient at sorting the problem, which was stopped a leaking pipe. He wore a medical mask and gloves , and was very aware of social distancing and of not touching surfaces unnecessarily, enabling my lodger to remain safely at work in the same room whilst he was there. He is very polite and friendly and gives a clear explanation of what needs doing. He is my go-to person whenever I need a plumber, having been here three times now, and I highly recommend him .

FAQ:

Do you offer same-day emergency plumbing services?

Yes we provide same-day emergency plumbing services across London. Whether it’s a burst pipe, water leak, blocked drain or broken boiler, we aim to respond as quickly as possible to get your system back up and running. Our team is available for urgent callouts and always carries the tools and parts needed to fix most issues on the first visit.

When you call, we’ll take a few details about the problem, advise you on any immediate steps to limit damage and send the nearest available engineer to your location. Our plumbers are fully trained to handle all types of emergencies, from residential faults to commercial breakdowns.

We understand that plumbing problems can’t wait, especially when they cause water leaks or heating loss. That’s why we prioritise same-day service whenever possible.

Which areas of London do you cover?

We cover all areas of London & Greater London. Our engineers and plumbers are based across North, South, East, and West London, so we can respond quickly no matter where you’re located. We regularly serve homes and businesses in areas such as Westminster, Camden, Islington, Hackney, Greenwich, Croydon, Ealing, Hammersmith, Richmond, and beyond.

We also work in parts of Greater London and nearby areas, depending on the job type and urgency. If you’re not sure whether we cover your postcode, just give us a call, chances are, we do.

Because we have engineers based across the city, we can usually reach you the same day for emergencies. For planned work such as boiler installations, powerflushing, or heating upgrades, we’ll schedule a time that suits you. Our focus is on reliability and coverage, ensuring London homes and businesses have a dependable local team whenever they need us.

How often should I service my boiler?

Your boiler should be serviced once a year to keep it running safely and efficiently. Annual servicing helps prevent breakdowns, reduces energy use and ensures your warranty remains valid.

During a service, an engineer will inspect all major components, clean the burner and heat exchanger, check gas pressure, test safety controls and make sure there are no leaks or carbon monoxide risks. If small faults are spotted, they can be fixed before turning into expensive repairs.

Regular servicing also keeps your central heating working properly and helps extend the lifespan of your boiler. It’s especially important before winter, when your heating system is in constant use.

If you’re a landlord, you’re legally required to have an annual gas safety check on any rented property but homeowners benefit just as much from keeping their boiler maintained yearly.

Are your engineers certified?

Yes all our engineers and plumbers are fully certified, trained and Gas Safe registered. This means they’re legally qualified to work on gas appliances, boilers, and central heating systems. Every engineer carries their Gas Safe ID and you can always ask to see it before any work begins.

In addition to Gas Safe certification, our team is experienced in all areas of plumbing, heating, and electrical work. We keep up to date with the latest safety standards and manufacturer training so every job is carried out correctly and safely.

It ensures your system is repaired or installed to the highest standard and guarantees your safety. Whether you need an emergency repair, installation, or inspection, you’ll always get a qualified professional on-site.

Can you help with gas safety certificates for landlords?

Yes we carry out Gas Safety Inspections (CP12 certificates) for landlords across London. If you rent out a property with gas appliances, it’s a legal requirement to have them inspected annually by a Gas Safe registered engineer.

Our team can test all boilers, gas fires and pipework to make sure everything is safe and compliant. Once the inspection is complete, we’ll issue your Gas Safety Certificate straight away, either digitally or in print.

We also offer reminders when your next inspection is due, making it easy to stay compliant without last-minute stress. For landlords managing multiple properties, we can schedule inspections in batches to save time and avoid certificate gaps.

What is power flushing, and why is it important?

A power flush is a deep clean for your central heating system. Over time, rust, sludge and debris build up inside pipes and radiators, causing cold spots, noisy operation and reduced efficiency. Powerflushing uses a specialist machine and cleaning solution to clear this buildup and restore proper water flow.

It’s especially important before fitting a new boiler, as sludge from an old system can damage new components. Powerflushing also helps improve heating performance, reduces energy waste and extends the life of your boiler and radiators.

You don’t need one every year, but if your radiators aren’t heating properly or your system makes gurgling noises, it’s usually a good time to book one. It’s a safe, effective process that leaves your heating system running like new again.

Do you provide free quotes?

Yes we offer free, no-obligation quotes for all plumbing, heating, and installation work. Whether you need a boiler replacement, bathroom refurbishment, powerflush, or general plumbing repair, we’ll assess the job and provide a clear breakdown of the work involved.

Our quotes are transparent and easy to understand, with no hidden charges. In most cases, we can give an estimate over the phone or by email and for larger projects we’ll arrange a site visit to give you an accurate written quote.

We believe in honesty and straightforward pricing what we quote is what you pay. There’s no pressure to commit and we’re always happy to answer questions or explain your options before any work starts.
