Boiler Repairs Questions & Answers

It's understood you've got questions about getting your boiler fixed, and we're here to help with straightforward answers about costs, timing, and guarantees.
When your boiler breaks down, you'll want to know how quickly we can get to you, what it might cost, and whether you need a repair or just a service.
Let's cover the most common questions we get from our Borough Green customers, including our Gas Safe credentials and what you can expect when you work with us.
For typical repairs, our 12-month parts guarantee provides peace of mind when we replace components during maintenance visits.
How much will it cost to fix my boiler?
Determining the exact cost of a boiler repair isn't straightforward, as prices vary considerably based on the problem's complexity and required parts.
We've found that some common boiler issues can be resolved within an hour with no parts needed, costing just our standard labour rate. However, if major components like pumps, fans, or circuit boards need replacing, repairs can take 2-3 hours plus parts (£150-£350).
During our initial diagnostic visit, we'll assess your boiler's condition and provide a clear estimate of the total repair cost.
While dealing with boiler maintenance tips is essential for preventing costly repairs, we recognise that sometimes breakdowns are unavoidable.
That's why we're committed to offering transparent pricing and honest assessments, so you'll always know exactly what you're paying for.
With our Gas Safe registration since 2002, you can trust that all repairs meet strict safety standards and regulations.
How soon can you fix my boiler?
Booking availability for boiler repairs varies considerably depending on the season.
During summer months, when we're dealing with fewer common boiler issues, we can usually get to you within a day or two. However, in winter, when everyone's heating systems are working overtime, wait times can stretch to a couple of weeks due to high demand.
While you're waiting for your appointment, we've got some helpful boiler troubleshooting tips on our website that might help you identify simple problems.
We understand it's frustrating when your boiler isn't working properly, and we'll do our best to fit you in as soon as possible.
For the most up-to-date scheduling options, check our online booking system at booking.thamesboilers.co.uk – it'll show you our next available slots.
Our Gas Safe registered engineers are qualified to work on all major brands including Worcester Bosch, Vaillant, and Potterton.
What guarantees do you offer on boiler repairs?
A straightforward 12-month guarantee covers any parts we replace during your boiler repair. If any of these parts fail within this period, we'll replace them at no cost to you – it's that simple.
Our guarantee details are clear and transparent, so you know exactly what's covered.
However, it's important to understand the scope of our warranty coverage. While we stand behind the parts we replace, the guarantee doesn't extend to other components that might develop issues after your repair.
For instance, if we replace your pump and it fails within 12 months, we'll sort that out free of charge. But if your fan develops a fault later, that would require a separate repair visit and payment.
Gas Safe registered engineers perform all repairs to ensure your safety and compliance with regulations.
Should I book a boiler service or a repair?
The key difference lies in what you're trying to achieve. If your boiler isn't working properly – perhaps you've got no hot water, low pressure, or strange noises – you'll want to book a repair visit.
Common boiler issues like these need diagnostic work to identify and fix the problem. A service, on the other hand, is more like an annual health check for your boiler when it's running normally.
Think of it like your car – you wouldn't book a routine service if your engine wasn't starting or making concerning sounds.
Similarly, one of our most important boiler maintenance tips is to address problems promptly with a repair visit rather than waiting for your next service. This guarantees we can tackle the specific issue head-on and get your heating back to normal quickly.
For unvented hot water systems, our Gas Safe registered engineers ensure all repairs meet strict safety standards and compliance requirements.
Are you gas safe registered?
Yes, we're a fully Gas Safe registered company with certification dating back to 2002 (formerly CORGI).
Our founder, George Lane, has maintained continuous Gas Safety registration throughout his career, demonstrating our unwavering commitment to your safety and peace of mind.
We understand that when it comes to gas work in your home, you want absolute certainty that you're dealing with qualified professionals.
That's why we're proud to have completed the rigorous Registration Process and ongoing training required to maintain our Gas Safe status.
You can rest assured that every boiler repair we undertake follows strict safety protocols and industry standards.
We believe in doing things right the first time, which is why local homeowners in Borough Green have trusted us with their boiler repairs since 2017.
Our commitment to safety extends through winter months when gas appliance maintenance becomes especially critical for protecting your home and family.

Common Boiler Problems In Borough Green

We've seen lots of boiler problems in Borough Green over the years, and some issues come up more often than others.
Whether it's a combi boiler that's not giving hot water, radiators that won't heat up, or pressure that keeps dropping, we recognise how frustrating these problems can be.
If you're experiencing any of these common issues, like hot water running hot and cold or seeing a fault code on your display, we'll help you get to the bottom of what's wrong and fix it properly.
No hot water but heating is working
When your boiler provides heating but no hot water in Borough Green, it typically indicates one of two common issues.
For combi boilers, we often find it's either a faulty flow switch or a stuck diverter valve that's causing the problem. These components are essential for directing hot water where it needs to go.
If you've got a conventional boiler system, we usually discover it's a faulty motorised valve that's behind your hot water troubles.
While heating troubleshooting can seem challenging, we're here to help identify and fix these issues quickly.
We've seen these problems countless times in Borough Green homes, and we understand exactly what to look for.
It's always best to have a professional check these issues, as they often require specific expertise to repair correctly.
Hot water is working, but radiators are not heating up
If your radiators aren't heating up but you've got hot water in your Borough Green home, there are several potential causes we commonly find.
During our radiator troubleshooting visits, we often discover it's due to a stuck diverter valve in combi boilers or a faulty motorised valve in conventional systems.
Before you call us, there's a simple check you can do to improve your heating efficiency: make sure your programmer is set correctly and your room thermostat is turned up high enough.
We've had many customers who've been relieved to find it was just a thermostat setting!
If these quick checks don't solve the problem, it could be something more technical that needs our expertise.
As your local heating specialists, we're here to help get your radiators working properly again.
Boiler Pressure gauge keeps going down
A dropping boiler pressure in your Borough Green home often signals a leak somewhere in your heating system. When you notice your pressure gauge constantly dropping, we'll first check for visible leaks around your pipes and radiators.
One common culprit we often find is water escaping from the pressure relief valve outside.
Sometimes, a faulty expansion vessel can cause your boiler pressure to drop repeatedly. It's a bit like having a slow puncture in your car tyre – you keep topping it up, but the pressure won't hold.
We've seen this issue quite a lot in Borough Green homes, and while it might seem like a minor annoyance, it's best to get it checked out quickly.
Left unchecked, constant pressure drops can lead to bigger problems and potentially damage your heating system.
Hot water on combi boiler runs hot and cold
Temperature fluctuations in your hot water can be just as frustrating as pressure problems.
If you're experiencing hot and cold water changes with your combi boiler, you're not alone – this is one of the most common issues we encounter during our combi boiler troubleshooting visits in Borough Green.
When your hot water temperature keeps fluctuating, there are typically two main culprits we look for.
In most cases, it's down to a blocked plate heat exchanger in your boiler.
Think of it like a clogged filter that needs clearing to work properly.
However, if you're only noticing these hot water issues when using your shower, the problem might actually be a faulty shower cartridge rather than your boiler system itself.
There's a fault code on my boiler
Modern boilers display fault codes to help diagnose problems when something's not working correctly. While these codes might seem confusing at first, they're actually quite helpful for fault code troubleshooting and understanding what's wrong with your boiler.
When you see a code appear on your display, don't panic! A quick online search with your boiler make and the specific code (for example, "Vaillant F75") can give you insight into the error code meanings. This can help you understand whether it's a simple issue you might resolve yourself, like low pressure, or if you'll need professional help.
At Thames Boilers, we're familiar with all the common fault codes and can quickly diagnose what's causing them. If you're unsure about what your boiler's trying to tell you, we're here to help.
Boiler is making a loud banging sound when it turns on
Loud banging sounds from your boiler can be quite alarming when it first starts up. We often hear from our Borough Green customers who are worried about these unsettling noises, and we recognise your concern.
When it comes to boiler noise causes, there's usually a straightforward explanation. The most common reason is that water isn't circulating properly through your heating system, which leads to overheating.
This is typically due to a faulty pump, though sometimes air trapped in the system or a blocked main heat exchanger could be the culprit.
Regular heating system maintenance can prevent these issues from developing. If you're hearing these concerning sounds, it's best to get them checked out promptly – we'll help identify the root cause and get your boiler running quietly again.
