Boiler Repairs Questions & Answers
It's understood you've got questions about boiler repairs, and we're here to answer the most common ones we hear from our Bexley customers.
From repair costs and timeframes to our Gas Safe registration and service guarantees, we'll help you understand exactly what to expect when you book with us.
Whether you're wondering if you need a repair or just a service, or you're curious about our 12-month parts guarantee, we've got clear, straightforward answers to help you make informed decisions about your boiler.
During colder months, you may need to plan ahead as repair wait times can extend up to 2 weeks compared to next-day service availability in summer.
How much will it cost to fix my boiler?
Pinning down an exact cost for boiler repairs can be challenging without a proper diagnosis.
The repair pricing really depends on what's wrong with your boiler and which parts might need replacing. Some fixes are straightforward, taking just an hour with no parts needed – you'll only pay for our labour time in these cases.
For more complex issues, like replacing major components such as pumps, fans, or circuit boards, you're looking at 2-3 hours of labour plus parts (which typically range from £150-£350).
When we visit for the initial diagnostic, we'll be able to give you a clear picture of the total boiler cost.
We believe in being upfront about pricing, so you'll always know what to expect before we start any work.
As a Gas Safe registered company since 2002, we ensure all repairs meet strict safety compliance standards.
How soon can you fix my boiler?
Booking availability for boiler repairs varies depending on the season.
During summer months, we can usually get to you within a day or two, which is perfect for addressing common boiler issues before winter arrives. However, when temperatures drop and heating systems are working overtime, our schedule gets much busier.
In the colder months, you might need to wait a couple of weeks for an appointment due to high demand. That's why we always recommend following proper boiler maintenance tips, like getting your annual service done in summer. This helps prevent breakdowns during peak season when wait times are longer.
For the most up-to-date availability and to book your repair, visit our online booking system at booking.thamesboilers.co.uk. We'll do our best to accommodate your schedule and get your heating back up and running.
Gas Safe registered engineers are available to provide prompt and professional service when you need it most.
What guarantees do you offer on boiler repairs?
A straightforward 12-month guarantee comes with all replacement parts used in our boiler repairs.
We'll replace any faulty parts we've installed free of charge if they fail within this time frame. Our warranty information is simple and transparent – we want you to know exactly what you're covered for.
It's important to understand our guarantee details, though.
While we stand behind the parts we replace, other components that might develop issues aren't included in this coverage.
For example, if we replace your pump and it fails within 12 months, we'll sort that out at no cost.
However, if your heat exchanger develops a fault later, that would need a separate repair visit and charge.
As Gas Safe registered engineers since 2017, we ensure all repairs meet strict safety and quality standards.
Should I book a boiler service or a repair?
When your boiler isn't working properly, you'll need to book a repair rather than a service.
While boiler maintenance tips often recommend annual servicing, it's important to understand that a service is just routine maintenance – like a health check-up for your boiler. It won't fix existing problems.
Think of it this way: if your car breaks down, you wouldn't book it in for a standard service, would you? The same applies when choosing repair services for your boiler.
If you're experiencing issues like no heating, no hot water, strange noises, or leaks, you'll need a repair visit.
We'll diagnose the specific problem and get your heating system back up and running efficiently, rather than just performing routine maintenance checks.
For your safety and legal compliance, always ensure your repair work is completed by Gas Safe registered engineers who are qualified to work on gas appliances.
Are you gas safe registered?
Safety is our top priority, and yes, we're fully Gas Safe registered. We recognise that when it comes to gas work in your home, you need complete peace of mind that you're working with qualified professionals who take Gas Safety seriously.
Our Registration Importance can't be overstated – it's not just a legal requirement, it's our commitment to protecting your family.
You might be wondering what this means for you. Well, every time we visit your home, you can verify our credentials right on the spot.
We carry our Gas Safe ID card with us at all times, and you're welcome to check our registration number online. It's just one of the ways we guarantee you feel confident and secure when choosing Thames Boilers for your boiler repairs in Bexley.

Common Boiler Problems In Bexley
At Thames Boilers, we've seen just about every boiler problem you can imagine in Bexley homes, from mysterious fault codes to frustrating hot water issues.
The most common problems we fix include no hot water despite working heating, radiators that won't heat up even though the hot water works, dropping boiler pressure, and combi boilers that run hot and cold.
We recognise how disruptive these issues can be to your daily routine, which is why we're ready to tackle them with solutions that work for both your home and your budget.
No hot water but heating is working
A cold morning shower can be frustrating when you discover your boiler is producing heat for your radiators but not delivering hot water.
We see this problem quite often in Bexley homes, and it's one of the most common boiler maintenance tips we share with our customers.
If you've got a combi boiler, the usual suspects are either a faulty flow switch or a stuck diverter valve.
For those with conventional boilers, we typically find it's down to a faulty motorised valve.
While these might sound technical, they're issues we're very familiar with at Thames Boilers.
If you're experiencing this problem, don't worry – it's generally a straightforward fix for our experienced engineers, and we'll have your hot water running again in no time.
Hot water is working, but radiators are not heating up
When your hot water taps are running fine but your radiators remain cold, it's often due to a few common issues we frequently encounter in Bexley homes.
During our heating system diagnostics, we typically find that combi boilers might've a stuck diverter valve, while conventional boilers usually show signs of a faulty motorised valve.
Before you call us for radiator troubleshooting, there are a couple of quick checks you can do yourself.
First, make sure your programmer is actually set to turn the heating on – we've lost count of how many times this simple setting has been the culprit!
Also, check that your room thermostat is turned up high enough.
If these basic checks don't solve the problem, we'll need to take a closer look to get your heating back up and running.
Boiler Pressure gauge keeps going down
Maintaining proper boiler pressure is essential for efficient heating, which is why a constantly dropping pressure gauge often concerns Bexley homeowners.
We find that this common issue usually points to a leak somewhere in your heating system. In our experience, the most likely culprits are leaks from the pressure relief valve outside your home or small drips from pipes and radiators.
We'll often check these areas first when diagnosing pressure problems. If there's no visible leak, a faulty expansion vessel might be the cause – it's a part that helps maintain stable pressure in your system.
If you're noticing your boiler pressure keeps dropping, we recommend getting it checked promptly.
While it might seem minor, addressing pressure issues early can prevent more serious problems down the line.
Hot water on combi boiler runs hot and cold
Fluctuating hot water temperatures from combi boiler issues frequently frustrate Bexley residents, especially during morning showers.
It's understood how annoying it can be when you're trying to enjoy a relaxing shower, only to be hit with sudden temperature changes that leave you jumping around to avoid the cold water!
In our experience, when your hot water runs hot and cold, it's usually down to a blocked plate heat exchanger in your combi boiler.
Think of it like a clogged filter that's preventing proper water flow.
If you're only experiencing this problem with your shower, though, don't worry – it's likely just a faulty shower cartridge that needs replacing.
We're here to help diagnose and fix these issues, getting your morning routine back to normal.
There's a fault code on my boiler
Seeing an unexpected fault code on your boiler display in Bexley can be concerning, but it's actually your boiler's way of telling you what's wrong.
Many of our customers find that a quick fault code analysis can help identify the issue before calling us out.
Here's a helpful troubleshooting tip we always share: try googling your boiler's make and the specific fault code (for example, "Vaillant F75"). This simple step can give you a better understanding of what's happening with your heating system.
While some fault codes indicate minor issues that can be resolved by resetting your boiler, others might point to more serious problems that need professional attention.
We're here to help if you're unsure about what your fault code means or need expert assistance.
Boiler is making a loud banging sound when it turns on
When your boiler starts making loud banging noises in Bexley, it's often a sign of restricted water circulation causing overheating. This can be pretty alarming, but don't worry – we've seen this issue many times and know exactly what to look for.
The most common cause is a faulty pump that's not circulating water properly through your system. Sometimes, it's trapped air that needs bleeding from your radiators, or in more serious cases, a blocked main heat exchanger.
These banging sounds shouldn't be ignored, as they can lead to more serious problems if left unchecked.
Regular boiler maintenance can help prevent these issues from occurring. If you're hearing these concerning noises, it's best to have a qualified engineer take a look to diagnose and fix the problem properly.
