Boiler Repairs Questions & Answers

We understand you've got questions about getting your boiler fixed in Petts Wood, and we're here to answer them all.
Whether you're wondering about repair costs, how quickly we can help, or what guarantees we offer, we'll give you straightforward answers with no surprises.
As trusted Gas Safe registered engineers serving Petts Wood homeowners since 2017, we'll help you understand if you need a repair or service, and exactly what to expect when you book with us.
Our expertise covers major boiler brands including Worcester Bosch, Vaillant, Potterton, Ideal, Alpha, Glow Worm, and Vokera.
How much will it cost to fix my boiler?
Boiler repair costs can vary considerably depending on the problem and required parts. Some repairs might only take an hour with no parts needed, so you'll just pay for our labour time.
Other issues requiring major components like pumps, fans, or circuit boards typically cost between £150-£350 for parts, plus 2-3 hours of labour.
When we visit, we'll diagnose your boiler's efficiency issues using proven repair techniques, giving you a clear estimate before proceeding.
We recognise that unexpected repairs can be stressful, which is why we're always upfront about costs. While we can't provide free quotes (as diagnosis requires skilled work), we'll thoroughly explain what's wrong and your options once we've examined your boiler.
You'll never face surprise charges or pressure to proceed with repairs.
For your peace of mind, we provide 12-month guarantees on all replacement parts installed during repairs.
How soon can you fix my boiler?
Understanding the timing of repairs is naturally the next concern after discussing costs.
While we'd love to fix your boiler right away, our availability varies with the seasons. During summer months, when common boiler issues are less frequent, we can usually get to you within a day or two.
However, in winter, when boiler maintenance tips are most essential and demand peaks, wait times might stretch to a couple of weeks.
We're always upfront about our scheduling, and we recognise waiting isn't fun when your boiler's acting up. That's why we encourage using our online booking system at booking.thamesboilers.co.uk – it'll show you our next available slot in real-time.
While we don't offer emergency or same-day services, we'll always do our best to accommodate you as quickly as possible.
Our Gas Safe registered engineers are ready to provide prompt service with over 25 years of experience in central heating repairs.
What guarantees do you offer on boiler repairs?
The guarantees on our boiler repairs are straightforward and transparent. When we repair your boiler, we provide a 12-month guarantee on any parts we replace. If these parts fail during this period, we'll replace them at no cost to you – it's that simple.
We're committed to customer satisfaction, but it's important to understand what our repair guarantees cover. While we stand behind the parts we install, our guarantee doesn't extend to other components that might develop issues later.
Think of it like getting a new tyre on your car – the new tyre is guaranteed, but that doesn't cover other parts that might wear out.
If you're unsure about our guarantee terms, just ask. We believe in being upfront about what we can and can't guarantee.
As a Gas Safe registered company serving Dartford, Gravesend, Bexley and surrounding areas, we ensure all repairs meet strict safety standards.
Should I book a boiler service or a repair?
Making the right choice between a boiler service and repair depends on your current situation.
If you're experiencing problems with your boiler, like no heating, strange noises, or low pressure, you'll want to book a repair visit. Common boiler issues need specific diagnosis and fixes, not routine maintenance.
A boiler service, on the other hand, is part of your regular boiler maintenance tips – it's like an annual health check when everything's working fine.
Think of it this way: if your car breaks down, you wouldn't book it in for a regular service, would you? You'd get it repaired first! The same goes for your boiler.
When something's not working right, we'll need to diagnose and fix the problem through a repair visit.
Our Gas Safe registered engineers ensure all repairs comply with current safety standards and regulations.
Are you gas safe registered?
Whether your boiler needs repairs or maintenance, working with a Gas Safe registered engineer isn't just recommended – it's a legal requirement in the UK.
At Thames Boilers, we take Gas Safety seriously, which is why we're proud to be fully Gas Safe registered since 2002.
When you choose us for your boiler maintenance needs in Petts Wood, you're not just getting an experienced engineer – you're getting peace of mind knowing your home and family are in safe hands.
We've built our reputation on providing reliable, professional service that meets all legal requirements and safety standards.

Regular winter servicing by Gas Safe engineers is especially crucial during the colder months when heating systems are under increased strain.

Common Boiler Problems In Petts Wood

In our years serving Petts Wood homeowners, we've seen quite a variety of boiler issues pop up time and time again.
From no hot water despite working heating (usually a diverter valve issue), to dropping pressure gauges that signal system leaks, these common problems can really throw a wrench in your daily routine.
We'll walk you through the most frequent boiler troubles we encounter in Petts Wood, including those frustrating hot-and-cold fluctuations and mysterious fault codes that leave you scratching your head.
No hot water but heating is working
Living with a boiler that provides heating but no hot water is a frustrating experience for many Petts Wood homeowners.
We often hear from customers who are dealing with this common boiler issue, and we realise how disruptive it can be to your daily routine.
When it comes to boiler troubleshooting tips, the cause usually depends on your type of boiler.
If you've got a combi boiler, we typically find it's either a faulty flow switch or a stuck diverter valve causing the problem.
For conventional boilers, a faulty motorised valve is often the culprit.
While these are common boiler issues we see in Petts Wood, it's important to have a Gas Safe registered engineer diagnose and fix the problem, as attempting repairs yourself could be dangerous.
Hot water is working, but radiators are not heating up
When your hot water flows perfectly but your radiators stay cold, it's a common issue we encounter with Petts Wood homeowners, especially during the winter months.
As your local heating experts, we've seen these radiator issues stem from a few typical causes.
For combi boilers, it's often a stuck diverter valve that's causing the problem. If you've got a conventional boiler, we usually find it's a faulty motorised valve that needs attention.
Before calling us, though, we'd recommend checking a couple of simple heating solutions: make sure your programmer is actually set to turn the heating on, and double-check that your room thermostat is turned up high enough.
It's surprising how often these quick fixes solve the problem, but if they don't, we're here to help.
Boiler Pressure gauge keeps going down
Another common heating issue Petts Wood residents face is a boiler pressure gauge that won't stay steady. When it comes to pressure gauge troubleshooting, there's usually a straightforward explanation – you've got a leak somewhere in your system.
As part of our boiler maintenance tips, we always tell our customers to look out for a few key signs.
Check for water dripping from the pressure relief valve outside your home, or inspect your pipes and radiators for small leaks. Sometimes, it's as simple as that.
In other cases, you might've a faulty expansion vessel that needs attention. If you're constantly having to top up your boiler pressure, it's time to get it checked out properly.
We can help identify and fix these issues before they become bigger problems.
Hot water on combi boiler runs hot and cold
Throughout the winter months, Petts Wood homeowners often report their combi boilers delivering inconsistent hot water temperatures.
If you're experiencing this frustrating issue of hot water running hot then cold, we recognise how disruptive this can be to your daily routine.
During our combi boiler maintenance calls, we frequently find that a blocked plate heat exchanger is the main culprit.
It's similar to how limescale builds up in your kettle – over time, these mineral deposits can restrict water flow.
If you're troubleshooting hot water problems and notice this issue only happens when using your shower, the problem might actually be a faulty shower cartridge instead.
In either case, we're here to help get your hot water running consistently again, ensuring your morning shower stays comfortable and steady.
There's a fault code on my boiler
A fault code flashing on your boiler's display in Petts Wood can be a concerning sight.
It's worrying when you're not sure what those mysterious numbers or letters mean, but don't panic just yet – we're here to help with your fault code troubleshooting needs.
Most modern boilers display fault codes to help identify specific issues, making it easier to diagnose problems.
While there are many common fault codes across different boiler brands, a quick online search of your boiler make and the specific code can give you a better understanding of what's wrong.
For example, if you have a Vaillant boiler showing an F75 code, you can look this up to get an initial idea of the problem before giving us a call.
Boiler is making a loud banging sound when it turns on
When your boiler starts making loud banging noises in Petts Wood, it's often a sign of poor water circulation causing the heat exchanger to overheat.
We commonly find this issue in local homes, and it's not something you should ignore.
Those boiler banging sounds, which some of our customers describe as "kettling," usually point to three main culprits: a faulty pump that's not circulating water properly, trapped air in your system, or a blocked heat exchanger.
Think of it like a kettle that's struggling to let steam escape – that's what's creating those loud noises in your boiler.
If you're hearing these concerning sounds, don't wait for the problem to worsen.
We can diagnose the exact cause and get your heating system running quietly again.
