Boiler Repairs Questions & Answers
It's understood you probably have questions about getting your boiler fixed in Mottingham, like how much it'll cost and how quickly we can help.
It's natural to wonder about guarantees, whether you need a repair or service, and if we're properly qualified to work on your boiler.
Our 12-month repair guarantee covers all replaced parts, giving you peace of mind about the quality of our work.
Let's answer these common questions so you can feel confident about booking your boiler repair with us.
How much will it cost to fix my boiler?
Determining an exact boiler repair cost without a diagnostic visit isn't possible, as issues can range from simple fixes to complex repairs.
Some issues might only need an hour of labour, while others could require several hours plus replacement parts.
For a typical repair, you'll pay for our diagnostic visit plus any additional labour and parts needed.
Parts like pumps, fans, or circuit boards can cost between £150-£350, and labour is charged at our standard hourly rate.
While we're there, we're happy to share boiler maintenance tips and discuss potential boiler efficiency upgrades that could help prevent future issues.
Rest assured, we'll always give you a clear breakdown of costs before proceeding with any repairs, so you'll know exactly what you're paying for.
Our 12-month guarantee covers all replacement parts we install during your boiler repair.
How soon can you fix my boiler?
Booking availability varies considerably depending on the season.
During summer months, when demand is lower, we can usually get to your boiler repair within a day or two. However, when temperatures drop and seasonal demand peaks, wait times can stretch to a couple of weeks.
While we recognise you'd like your boiler fixed right away, we don't offer emergency repairs or same-day service. We believe in doing thorough, quality work rather than rushing repairs.
The good news is you can check our real-time availability and book your repair slot instantly through our online booking system at booking.thamesboilers.co.uk. This way, you'll know exactly when we can help, and you won't have to wait around for a callback about scheduling.
Our streamlined booking process makes it convenient to schedule your boiler repair at any time of day or night.
What guarantees do you offer on boiler repairs?
All boiler repairs come with a 12-month guarantee on any replacement parts we install. If any part we've fitted fails during this period, we'll replace it completely free of charge – that's our promise to you.
We want you to feel confident in our work and know that you're protected.
It's important to understand our guarantee details and repair expectations clearly. While we stand behind the parts we replace, our guarantee doesn't cover new issues that might develop with other components of your boiler or heating system.
If different problems arise after our repair, these would need to be diagnosed and fixed separately. We believe in being upfront about this so you know exactly what's covered and what isn't.
As a Gas Safe registered company with full public liability insurance, we ensure all repairs meet strict safety and quality standards.
Should I book a boiler service or a repair?
The key difference between a repair and a service lies in your boiler's current condition.
If your boiler isn't working properly – perhaps it's making strange noises, losing pressure, or not heating your water – you'll need to book a repair visit. These common boiler issues require diagnostic work to identify and fix the problem.
A service, on the other hand, is like an annual health check for your boiler.
It's part of regular boiler maintenance tips we recommend to keep your system running smoothly. Think of it like going to the dentist – you don't wait until you have a toothache to schedule a checkup!
When your boiler's working fine but needs its yearly maintenance, that's when you book a service. For any current problems, always choose a repair visit.
During winter months, it's especially crucial to have your boiler checked by qualified gas engineers to ensure both safety and optimal performance.
Are you gas safe registered?
Safety credentials matter when it comes to your boiler, and yes – we're fully Gas Safe registered.
Since 2002, we've been committed to maintaining the highest standards of gas safety in every home we visit. When you choose Thames Boilers for your boiler maintenance, you're working with professionals who take your family's safety seriously.
You might've heard that all gas engineers need to be Gas Safe registered – and that's absolutely right. It's not just a nice-to-have, it's a legal requirement.
We proudly carry our Gas Safe ID card to every job, and we're always happy to show it to you. After all, your peace of mind matters to us.
Feel free to verify our credentials anytime through the official Gas Safe Register.

Common Boiler Problems In Mottingham
In our years serving Mottingham homeowners, we've seen quite a range of common boiler problems, from loss of hot water to strange banging noises.
Whether you're dealing with fluctuating water temperatures, dropping pressure, or mysterious fault codes on your display, these issues can be incredibly frustrating when they pop up.
We'll walk you through some of the most frequent boiler problems we encounter in Mottingham and what they might mean for your heating system.
No hot water but heating is working
When your heating works but there's no hot water in your Mottingham home, the issue usually stems from either a faulty flow switch or a stuck diverter valve in combi boilers, or a faulty motorised valve in conventional boilers.
As your local boiler experts, we've seen these common boiler issues countless times, and we're here to help with reliable boiler troubleshooting tips.
While it might be tempting to try fixing this yourself, we always recommend having a Gas Safe registered engineer diagnose the problem properly. These components are complex and need professional expertise to repair safely.
We understand how frustrating it can be when you're ready for a hot shower and there's only cold water coming through.
That's why we're just a quick booking away, ready to get your hot water flowing again.
Hot water is working, but radiators are not heating up
The opposite of our previous problem can be just as frustrating – you've got hot water flowing from your taps, but your radiators remain cold in your Mottingham home.
We often find these radiator issues have a few common causes that we can help identify with you.
For combi boilers, a stuck diverter valve is usually the culprit, while conventional boilers might've a faulty motorised valve.
Before you call us, though, here's a quick heating solution you can try: check that your programmer is set to turn the heating on and that your room thermostat is turned up high enough.
It's surprising how often these simple fixes solve the problem!
If you've checked these and you're still experiencing cold radiators, we're here to help diagnose and fix the issue properly.
Boiler Pressure gauge keeps going down
Many Mottingham homeowners notice their boiler pressure gauge slowly dropping over time, which can lead to heating problems if left unchecked.
When we're called out for boiler pressure troubleshooting, we typically find it's caused by a leak somewhere in the system.
We'll check common culprits like the pressure relief valve outside your home, which might be dripping water, or look for small leaks around your radiators and pipework.
Sometimes, it's a faulty expansion vessel that's causing the issue.
While it might seem tempting to keep topping up the pressure yourself, it's important to find and fix the root cause.
If you're experiencing recurring pressure problems with your boiler, we're here to help identify and resolve the issue properly.
Hot water on combi boiler runs hot and cold
Dealing with fluctuating hot water temperatures from your combi boiler can be particularly frustrating for Mottingham residents.
We're often called out to help local homeowners who are experiencing these hot water fluctuations, and we recognise how disruptive they can be to your daily routine.
When it comes to combi boiler troubleshooting, we typically find that a blocked plate heat exchanger is the most common culprit.
If you're only experiencing temperature changes when using your shower, it's likely due to a faulty shower cartridge instead.
The good news is, both issues are relatively straightforward for us to diagnose and fix.
We'll thoroughly inspect your system to determine the exact cause and get your hot water running consistently again, so you can enjoy those morning showers without any unexpected cold surprises.
There's a fault code on my boiler
Every modern boiler displays fault codes when something's not quite right, and for Mottingham residents, these mysterious combinations of letters and numbers can be concerning.
At Thames Boilers, we've become experts at fault code troubleshooting, helping our neighbours understand what their boilers are trying to tell them.
While there's no one-size-fits-all solution (since each manufacturer uses different codes), we've got a handy tip: try searching online for your boiler's make and the specific code you're seeing.
For example, if you've got a Vaillant showing F75, a quick search can give you initial insights during our boiler error analysis.
Of course, we're always here to help if you'd rather leave the detective work to us!
Boiler is making a loud banging sound when it turns on
After decoding fault messages, another concerning issue for Mottingham homeowners is when their boiler starts making loud banging sounds. If you're hearing these unsettling noises, you're not alone – it's a common problem that we observe in local homes.
When it comes to banging sound causes, there are several culprits that we typically find. The most common is poor water circulation, usually due to a faulty pump that's not moving water through your system properly.
Sometimes, trapped air in your pipes or a blocked main heat exchanger can also be behind these alarming noises. We understand these boiler noise solutions aren't always simple fixes, but they're essential to address quickly.
If left unchecked, these problems can lead to more serious issues with your heating system.
