Boiler Repairs Questions & Answers
We understand you've got questions about your boiler repair, and we're here to help clear things up.
From repair costs and appointment availability to our Gas Safe registration and service guarantees, we've got straightforward answers to put your mind at ease.
Whether you're wondering if you need a repair or just a service, or you're concerned about costs and timeframes, we'll walk you through everything you need to know.
We service a wide range of brands including Vaillant and Worcester plus many other major manufacturers.
How much will it cost to fix my boiler?
Boiler repair costs vary considerably depending on the problem and parts needed. Simple fixes might only require an hour of labour, while more complex issues involving major components can take 2-3 hours plus parts.
We'll always diagnose the issue first and provide you with a clear estimate before proceeding with any repairs.
For example, if your boiler's losing pressure or needs a minor adjustment to improve boiler efficiency, you'll typically only pay for our standard hourly rate.
However, if you need a replacement pump, fan, or circuit board, these parts can cost between £150-£350, plus labour.
One of our repair tips is to book a diagnostic visit as soon as you notice issues – catching problems early often means simpler, less expensive fixes and helps prevent bigger failures down the line.
Our Gas Safe registered engineers bring over 25 years of experience to every repair job we undertake.
How soon can you fix my boiler?
Booking availability for boiler repairs depends heavily on seasonal demand.
During summer months, when common boiler issues are less frequent, we can usually get to you within a day or two. However, winter's a different story – that's when everyone's heating is working overtime, and wait times can stretch to a couple of weeks.
We know it's frustrating when your boiler needs attention, which is why we recommend following regular boiler maintenance tips to prevent breakdowns during peak seasons.
Our online convenience system makes scheduling your boiler repair quick and hassle-free.
If you're looking to book a repair, the quickest way is through our online booking system at booking.thamesboilers.co.uk.
While we can't offer same-day or emergency services, we'll always do our best to find the earliest available slot that works for you, keeping you informed every step of the way.
What guarantees do you offer on boiler repairs?
Getting clear guarantees on repair work matters when you're investing in your boiler's maintenance. At Thames Boilers, we believe in being upfront about our guarantee policies and repair expectations, so you'll always know exactly where you stand.
When we repair your boiler, we provide a 12-month guarantee on any parts we replace. If these parts fail within that time frame, we'll replace them at no cost to you.
However, it's important to understand that our guarantee only covers the specific parts we've replaced. If other components develop issues or different problems arise with your heating system, these aren't covered under the original repair guarantee.
We find this straightforward approach helps build trust with our customers and guarantees everyone's on the same page.
Our founder's 25 years experience as a heating engineer ensures every repair is completed to the highest professional standards.
Should I book a boiler service or a repair?
If your heating system isn't working properly, you'll want to book a repair rather than a service. While both are important for maintaining boiler efficiency, they serve different purposes. A repair specifically addresses existing problems, like a lack of hot water or unusual noises, using proven repair techniques to get your system back up and running.
Think of it like your annual health checkup versus visiting the doctor when you're sick. A boiler service is preventive maintenance, checking everything's in good working order.
But when your boiler's already showing symptoms of trouble, you need a repair visit to diagnose and fix the specific issue. We'll assess the problem, explain what's wrong in plain English, and get your heating system back to its efficient, reliable self. Many issues like tripped overheat thermostats can cause complete loss of hot water and require immediate professional attention.
Are you gas safe registered?
Yes, we're fully Gas Safe registered and have been since 2002 (previously known as CORGI registration).
Having this registration means you can trust that we meet all the necessary safety standards and regulations required to work on gas appliances in your home. Our founder, George Lane, takes Gas Safety incredibly seriously and has maintained continuous registration throughout his 25-year career.

Common Boiler Problems In Sidcup
We often get calls from homeowners in Sidcup about some really common boiler issues that might seem scary at first but are usually quite fixable.
The problems we see most frequently include no hot water despite working heating, radiators staying cold while hot water works fine, dropping boiler pressure, fluctuating hot water temperature in combi boilers, and those mysterious fault codes that pop up on display screens.
As your local heating experts, we're familiar with all these issues and their causes, whether it's a stuck diverter valve, a system leak, or a blocked heat exchanger.
No hot water but heating is working
At one point or another, many Sidcup homeowners face the frustrating issue of having their heating work but no hot water coming from their taps.
When you're in the middle of your morning routine, there's nothing worse than discovering your shower's running cold!
If you're experiencing this common problem, we can help with your hot water troubleshooting.
For combi boilers, it's usually down to a faulty flow switch or diverter valve issues that need attention.
If you've got a conventional boiler system, the culprit is typically a faulty motorised valve that's not directing the hot water properly.
At Thames Boilers, we've seen these issues countless times in Sidcup homes, and we understand exactly how to get your hot water flowing again quickly and efficiently.
Hot water is working, but radiators are not heating up
Another frustrating boiler issue that Sidcup residents often face is when their hot water taps work perfectly, but their radiators remain cold.
We've seen this heating system problem quite often, and there are several common causes we check during our radiator troubleshooting.
For combi boilers, it's usually a stuck diverter valve that's causing the trouble.
With conventional boilers, we typically find it's a faulty motorised valve.
But before you call us, here's a quick tip: check your programmer settings and room thermostat first.
We often find that the heating's simply been turned off or the thermostat's set too low.
It's an easy fix that could save you time and money!
If you've checked these and you're still having problems, we're just a phone call away.
Boiler Pressure gauge keeps going down
Is your boiler's pressure gauge constantly dropping? We realise how frustrating this common issue can be for Sidcup homeowners. Let's help you comprehend what might be causing it.
When your boiler pressure keeps going down, it's usually due to a leak somewhere in your heating system. You might notice water dripping from the pressure relief valve outside your home, or there could be small, hard-to-spot leaks around your pipes and radiators.
Another culprit could be a faulty expansion vessel, which helps maintain steady pressure in your system.
We've helped many of your neighbours in Sidcup with this exact problem, and we appreciate how worrying it can be. If you're experiencing dropping pressure, it's best to have a professional take a look – we'll find that sneaky leak and get your system back to normal.
Hot water on combi boiler runs hot and cold
While checking boiler pressure is important, fluctuating hot water temperature can be equally frustrating for Sidcup residents.
We often hear from our customers about combi boiler issues where their hot water runs hot one minute and cold the next – it's like playing temperature roulette with your shower!
In our experience, hot water fluctuations usually point to one of two common problems.
If you're experiencing this issue throughout your home, it's typically due to a blocked plate heat exchanger in your combi boiler.
However, if you're only noticing temperature changes when using your shower, the culprit is more likely to be a faulty shower cartridge.
We'll help you pinpoint exactly what's causing your temperature troubles and get your hot water running consistently again.
There's a fault code on my boiler
Modern boilers in Sidcup homes display fault codes to help diagnose problems, but these cryptic numbers and letters can leave homeowners scratching their heads.
When you're facing fault code troubleshooting, we recommend a simple first step – grab your phone and search for your boiler's make followed by the specific code (for example, "Vaillant F75"). This quick search can give you insight into what's happening with your heating system.
While common error codes often point to issues like low pressure or ignition problems, it's important to remember that these codes are just indicators.
We've seen many Sidcup homeowners worry unnecessarily about fault codes, but they're actually your boiler's way of telling us exactly what needs attention.
Think of them as your boiler's way of communicating – they're helpful diagnostic tools.
Boiler is making a loud banging sound when it turns on
A loud banging noise from your boiler can be quite alarming, especially when it fires up in the morning. We realise how unsettling these banging noise causes can be, and they're often a sign that your boiler needs attention right away.
In most cases, this worrying sound happens because there's no proper water circulation in your system, leading to overheating issues. It's similar to when a kettle runs dry – except this is happening in your boiler!
The main culprits are usually a faulty pump that's not moving water through the system, trapped air that's blocking the flow, or a blocked main heat exchanger.
If you're hearing these sounds, don't wait – let's take a look. We'll get your boiler running smoothly and quietly again, just like it should.
