Boiler Repairs Questions & Answers
We understand you've got questions about getting your boiler fixed in Sevenoaks, and we're here to answer the most common ones we hear from homeowners.
From repair costs and timelines to our Gas Safe credentials and service guarantees, we'll share everything you need to know to make informed decisions about your boiler repair.
Whether you're wondering if you need a repair or a service, or you're concerned about costs and warranties, we've got clear, straightforward answers that'll help put your mind at ease.
Our 12-month guarantee on replacement parts gives you complete peace of mind about the quality and reliability of our repair work.
How much will it cost to fix my boiler?
Every boiler repair is unique, making it challenging to provide an exact cost without a proper diagnosis.
While some repairs might only need an hour of labour, others could require several hours plus replacement parts.
To give you a clearer picture of potential boiler costs, repair estimates can range from a simple one-hour fix to more complex repairs requiring parts like pumps, fans, or circuit boards (which typically cost between £150-£350).
During our initial diagnostic visit, we'll assess your boiler's condition and provide you with a detailed breakdown of the repairs needed.
We believe in transparency, so we'll always explain what's wrong, what needs to be done, and the associated costs before proceeding with any work.
Combi boiler issues like faulty flow switches or diverter valves are common causes of no hot water problems.
How soon can you fix my boiler?
During peak winter months, our booking availability typically extends to a 2-week wait period due to high demand.
While we'd love to offer emergency boiler services, we've chosen to focus on providing scheduled, high-quality repairs rather than rushed solutions.
In the warmer months, we're usually able to get to you within a day or two, which is perfect for addressing those nagging boiler issues before winter arrives.
While you're waiting for your appointment, we're happy to share some basic boiler troubleshooting tips that might help restore your heating sooner.
Our Gas Safe registered engineers specialize in servicing all major brands including Worcester Bosch, Vaillant, and Potterton.
You can easily check our current availability and book your preferred time slot through our online booking system at booking.thamesboilers.co.uk.
We'll keep you updated with real-time tracking once we're on our way.
What guarantees do you offer on boiler repairs?
Trust in repair work matters, which is why our guarantees are straightforward and transparent. When we repair your boiler, we provide clear boiler warranties that protect your investment and give you peace of mind.
All replacement parts we install come with a thorough 12-month guarantee. If any of these parts fail during this period, we'll replace them at no cost to you.
We believe in keeping things simple and honest with our repair guarantees, just as we'd want for our own homes.
It's important to note that our guarantee covers only the specific parts we've replaced. If other components develop issues later, they'll need separate attention.
We're always upfront about this because we want you to feel confident in understanding exactly what's covered.
Our Gas Safe registered engineers ensure all repair work meets strict safety standards and compliance requirements.
Should I book a boiler service or a repair?
When your boiler isn't working properly, it's important to book the right type of appointment. While both services and repairs are essential for your boiler's health, they serve different purposes.
A boiler service is like an annual health check-up – it's routine maintenance that helps prevent future problems. But if your boiler's already acting up, you'll need to book a repair visit instead.
Think of it this way: when your car breaks down, you don't take it in for a regular service – you get it fixed first! Common repair issues, like no heating or hot water, need immediate attention.
That's why we always recommend booking a repair appointment when something's not working right. Regular maintenance tips are great for prevention, but they won't fix an existing problem.
With our Gas Safe registration and extensive experience, we ensure every repair meets the highest safety standards while resolving your boiler issues.
Are you gas safe registered?
Speaking of getting the right help for your boiler, you'll want to make sure your engineer is properly qualified.
We're proud to confirm that yes, we're fully Gas Safe registered, which means we're legally qualified to work on your gas appliances. This isn't just a nice-to-have – it's essential for your safety and peace of mind.
When it comes to Boiler Maintenance and repairs, we take Gas Safety incredibly seriously.
After all, we've been handling gas appliances since 2002, when the register was still known as CORGI. You can trust that when we visit your home in Sevenoaks, you're getting a properly qualified professional who'll keep your family safe while fixing your heating issues.
It's just one more way we look after our local community.
You can verify our credentials anytime through the Gas Safe Register to ensure complete peace of mind.

Common Boiler Problems In Sevenoaks
At Thames Boilers, we've seen just about every boiler problem you can imagine in Sevenoaks homes, from no hot water with working heating to those pesky pressure gauge issues. Our experienced team is equipped to handle these challenges efficiently, ensuring your home stays comfortable year-round. We also specialize in unvented hot water cylinder servicing, which is crucial for maintaining optimal performance and safety in your plumbing system. With our comprehensive approach, you can trust us to keep your boiler running smoothly and your hot water flowing without interruption.
We're aware it's frustrating when your combi boiler starts running hot and cold, or when mysterious fault codes pop up on your display screen.
Whether your radiators aren't heating up or your boiler's making strange noises, we'll walk you through the most common issues we encounter and help you understand what might be causing them.
No hot water but heating is working
One of Sevenoaks' most frustrating boiler issues occurs when you've got heating but no hot water.
As part of our boiler troubleshooting tips, we often find this common heating issue has different causes depending on your boiler type.
If you're using a combi boiler, we typically see this problem stemming from either a faulty flow switch or a stuck diverter valve.
For those of you with conventional boilers, it's usually down to a faulty motorised valve that needs attention.
We know how disruptive it can be when you're ready for a morning shower, and there's no hot water!
While these issues might sound complex, they're actually quite common in Sevenoaks homes, and we're here to help get your hot water flowing again.
Hot water is working, but radiators are not heating up
Winter mornings in Sevenoaks can be especially challenging when your radiators aren't warming up, even though your hot water's working fine.
We often find that radiator troubleshooting leads us to a common culprit – a stuck diverter valve in combi boilers or a faulty motorised valve in conventional systems.
Before you call us, here's something you can check: make sure your programmer is set correctly for heating and that your room thermostat is turned up.
It's a simple step that's easy to overlook! If that doesn't improve your heating efficiency, there might be an issue with your room thermostat or programmer.
We'll help you get to the bottom of it and have your home cosy again in no time.
Boiler Pressure gauge keeps going down
Dealing with a constantly dropping boiler pressure is one of the most common issues we encounter in Sevenoaks homes.
When you notice your pressure gauge repeatedly falling below the normal range, it's usually a sign of a leak somewhere in your system.
We'll often find water escaping from the pressure relief valve outside, or spot small leaks around pipes and radiators.
Sometimes, it's not even visible – the leak could be hidden under floorboards or behind walls.
In other cases, a faulty expansion vessel might be the culprit.
If you're constantly having to top up your boiler pressure, don't ignore it.
It's best to have us take a look before it leads to more serious problems with your heating system.
Hot water on combi boiler runs hot and cold
Fluctuating water temperature from your combi boiler in Sevenoaks is often a telltale sign of a blocked plate heat exchanger.
When you're dealing with hot water issues like this, it's frustrating to get that blast of cold water mid-shower, as we understand!
During our combi boiler troubleshooting visits in Sevenoaks, we've found that while a blocked heat exchanger is the most common culprit, the problem might also be with your shower itself.
If you're only experiencing temperature fluctuations when using the shower, it could be a faulty shower cartridge that needs replacing.
We can help identify exactly what's causing your hot water to run hot and cold, ensuring you get back to enjoying consistent, comfortable temperatures throughout your home.
There's a fault code on my boiler
Fault codes on your boiler's display can seem like a mysterious warning at first, but they're actually helpful diagnostic tools that tell us exactly what's wrong.
When it comes to fault code troubleshooting, we recommend starting with a quick online search of your boiler's make and the specific code (for example, "Vaillant F75"). This simple step can give you valuable insights before calling us.
While boiler error analysis might sound technical, these codes are designed to pinpoint problems quickly. Think of them as your boiler's way of communicating – it's letting you know something needs attention.
If you're seeing a fault code in Sevenoaks, don't worry! We're here to help decode the message and get your heating back up and running efficiently.
Boiler is making a loud banging sound when it turns on
A loud banging noise from your boiler is often a serious warning sign that requires immediate attention. When it comes to troubleshooting banging noises, we typically find the root cause is a lack of proper water circulation, which can lead to overheating in your system.
Let's look at the most common boiler noise causes we encounter in Sevenoaks homes. The primary culprit is usually a faulty pump that's not moving water through your system effectively.
Sometimes, it's trapped air in your pipes, or in more serious cases, a blocked main heat exchanger.
Whatever the cause, these issues shouldn't be ignored – they can lead to more expensive repairs if left unchecked. If you're hearing these concerning sounds, we'll help diagnose and fix the problem before it gets worse.

Frequently Asked Questions
How Long Does a Typical Boiler Repair Appointment Take?
We'll usually complete your boiler repair within 1-2 hours, though repair duration can vary based on the issue. That's why we offer flexible appointment scheduling through our online booking system for your convenience.
What Payment Methods Do You Accept for Boiler Repairs?
We accept all major credit and debit cards, bank transfers, and cash payments for your convenience. Whilst we don't currently offer financing plans, we'll always provide upfront pricing so you know exactly what to expect.
Do I Need to Prepare Anything Before the Engineer Arrives?
We recommend clearing the area around your boiler for easy access. Please make certain someone over 18 is home and your boiler is accessible. It's helpful if you note any specific issues you've noticed recently.
Are Spare Parts Included in the Repair Cost?
We'll need to charge separately for any spare parts needed during your repair. While our labour costs are fixed, parts pricing varies depending on what's required to get your boiler running properly again.
Can You Repair My Boiler if It's Still Under Warranty?
We recommend checking your warranty coverage first. If your boiler's still under warranty, you'll need to contact your manufacturer for repair options, as working on it ourselves could void your valuable protection.
