Customer Reviews
Our Gas Safe certified engineers have been delivering reliable heating solutions across South London since 2002.
Benefits of Servicing Your Unvented Cylinder
Regular servicing of your unvented hot water cylinder isn’t just about ticking a box – it’s essential for keeping your home’s hot water system running safely and efficiently.
When you stay on top of maintenance, you’ll enjoy consistent hot water delivery and avoid costly breakdowns.
One of the main unvented cylinder advantages is their ability to deliver high-pressure hot water throughout your home.
But to maintain this performance, regular checks are vital.
We’ve seen how proper maintenance importance extends beyond just functionality – it helps protect your investment and gives you peace of mind.
With Gas Safe registration, Thames Boilers ensures all cylinder servicing meets strict safety compliance standards.
Unvented Cylinder Repairs In South London
When your unvented cylinder starts acting up, it’s crucial to address repairs quickly to prevent bigger problems down the line.
We’ve seen common faults that many homeowners face with their unvented cylinders, and we understand exactly what to look for.
If you notice water dripping from your overflow pipe or tundish, it could mean you’ve got a faulty pressure relief valve or expansion vessel that needs attention.
Poor hot water pressure? That’s often down to issues with the cold water combination valve.
And if you’re getting no hot water at all, we typically find it’s an overheat thermostat that’s tripped and needs resetting.
Regular unvented cylinder maintenance helps catch these issues early, saving you from those dreaded cold showers and costly emergency repairs.

Frequently Asked Questions About Unvented Hot Water Cylinder Servicing in South London
We understand you’ve got questions about unvented cylinder servicing, and we’re here to clear things up.
Whether you’re wondering if a service will fix existing problems (it won’t), or if you’re curious about our special G3 qualifications for working on systems like Megaflo cylinders, we’ve got straightforward answers.
For your convenience, we can even service your boiler during the same visit.
As members of the Gas Safe Register, we maintain strict compliance with all safety standards and regulations for your peace of mind.
Will a service fix any problems with my unvented cylinder?
Many homeowners wonder if a routine service will resolve existing problems with their unvented cylinder – but it’s important to understand that a service isn’t the same as a repair.
A service is a scheduled maintenance check that helps prevent future unvented cylinder issues, much like how a car’s MOT doesn’t fix existing problems.
When we perform a service, we’re checking components, inspecting safety devices, and ensuring everything’s working as it should.
However, if your cylinder is already showing signs of trouble – like inconsistent hot water or unusual noises – you’ll need to book a repair instead.
Think of it this way: maintenance tips and regular servicing help prevent breakdowns, but once something’s broken, it needs fixing.
That’s why we offer both services and repairs to keep your hot water running smoothly.
If my unvented cylinder develops a fault after a service, do I need to pay for another visit?
Unfortunately, a service doesn’t guarantee against future breakdowns – just like how getting your car serviced doesn’t prevent all possible future problems.
While we thoroughly check and maintain your cylinder during a service, unforeseen issues can still develop afterward.
If your cylinder develops a fault after its service, you’ll need to book a separate repair visit. This is because service and fault diagnosis are two different types of appointments with different purposes.
During a service, we’re performing preventative maintenance and safety checks within specific service limitations. When a fault occurs, we need to diagnose and fix the specific problem, which requires different tools and parts.
We know this might seem frustrating, but it’s similar to how your car might need repairs even after regular servicing – it’s just part of owning complex mechanical systems.
Is a Megaflo an unvented hot water cylinder?
Yes, Megaflo is indeed a popular brand of unvented hot water cylinder – you’ll often hear people use “Megaflo” as a generic term for unvented cylinders, similar to how people say “Hoover” for vacuum cleaners.
At Thames Boilers, we work with all major brands of unvented cylinders, including Megaflo. These systems are known for their excellent Megaflo features, including high water pressure and quick recovery times.
The unvented benefits you’ll enjoy include powerful showers and the ability to run multiple hot water outlets simultaneously without losing pressure.
We often tell our customers not to worry if they’ve a different brand – whether you’ve got a Megaflo or another manufacturer’s cylinder, we’ve got the expertise and qualifications to service it, keeping your hot water flowing reliably year-round.
Do you need special qualifications to work on unvented cylinders?
When it comes to working on unvented hot water cylinders, specific qualifications are absolutely essential.
We’re committed to following unvented cylinder regulations, which is why we’ve earned our G3 qualification – a specialised certification that’s required by law for working with these systems.
Not every Gas Safe registered engineer has this qualification, and that’s important for you to know.
The G3 qualification importance can’t be overstated because unvented cylinders operate under high pressure and need expert handling to guarantee your safety.
When you’re choosing someone to work on your cylinder, always make sure they’ve got this specific certification.
At Thames Boilers, we’ve got all the necessary qualifications to service your unvented cylinder safely and professionally, giving you complete peace of mind.
Can you service my boiler at the same time?
Many of our customers find it convenient to schedule their boiler and unvented cylinder services together, and we’re happy to accommodate that request.
When you book both services at once, you’re ensuring both systems are working efficiently together. Regular boiler maintenance and cylinder servicing help prevent unexpected breakdowns and keep your home’s hot water system running smoothly all year round.

We’ve made it easy to understand exactly what you’ll pay, with no hidden costs or surprises.
