Boiler Repairs Questions & Answers
We recognise you'll have questions about getting your boiler fixed, from costs and timelines to guarantees and what type of appointment to book.
As Gas Safe registered engineers, we're happy to walk you through everything you need to know about boiler repairs in Gravesend.
Let's tackle the most common questions we get from local homeowners about their boiler repairs.
Our digital service certificates provide detailed documentation of all work completed during repairs and maintenance visits.
How much will it cost to fix my boiler?
Most homeowners want to know repair costs upfront, but accurately pricing a boiler repair without diagnosis isn't possible.
While we recognise you're looking for cost effective repairs, every boiler issue is unique and requires proper assessment.
Some repairs might only need an hour of labour, while others could take 2-3 hours plus parts. For example, a simple fix might just cost our standard hourly rate, but if you need major components like pumps, fans, or circuit boards, you're looking at £150-£350 for parts alone.
That's why we'll need to book a diagnostic visit first – it's the only way we can give you an accurate quote. During this visit, we'll perform thorough boiler troubleshooting tips and provide you with a clear breakdown of what needs fixing and the total cost involved.
All replacement parts come with a 12-month guarantee to ensure your peace of mind after repairs are completed.
How soon can you fix my boiler?
Booking availability varies depending on the season and current demand.
During warmer months, we're typically able to fix common boiler issues within a day or two. However, when temperatures drop and heating systems are working overtime, our schedule fills up quickly, and you might need to wait a couple of weeks for an appointment.
While you're waiting, we recommend following basic boiler maintenance tips like checking your pressure gauge and ensuring radiators are bled properly.
These simple steps might even resolve minor issues before we arrive! For the most up-to-date availability, you can check our online booking system at any time.
We'll do our best to accommodate your schedule, and we're always happy to offer advice over the phone about keeping your boiler running smoothly until we can visit.
If you're experiencing issues with hot water but your radiators are cold, this could indicate a faulty diverter valve that needs professional attention.
What guarantees do you offer on boiler repairs?
Thames Boilers' guarantee on repairs covers replacement parts for 12 months from installation. If any part we've fitted fails during this time, we'll replace it completely free of charge – that's our commitment to standing behind our work.
When it comes to repair warranties and service guarantees, we believe in being upfront and honest with our customers.
While we'd love to guarantee every aspect of your boiler's operation, we can only warranty the specific parts we've replaced. This means if other components develop issues or different problems arise after our repair, they won't be covered under our guarantee, and additional visits will need to be charged.
We find this straightforward approach helps build trust with our customers and makes certain everyone knows exactly where they stand.
Our Gas Safe registered engineers have over 25 years of experience working with all major boiler brands to ensure quality repairs.
Should I book a boiler service or a repair?
The key difference between a boiler service and repair lies in their purpose. A service is like a health check-up for your boiler – it's routine maintenance designed to keep everything running smoothly.
On the other hand, if your boiler's already showing signs needing repair, like strange noises, leaks, or no heat, you'll want to book a repair visit.
We find that some of our customers book a service when they actually need a repair, which isn't quite right. Think of it this way: if your car breaks down, you wouldn't book it in for an MOT – you'd take it to get fixed!
The same applies to your boiler. Among our top boiler maintenance tips, we always recommend booking a repair when something's not working properly.
For optimal system performance, consider booking combined servicing of your boiler and unvented cylinder to maintain efficiency across your entire heating system.
Are you gas safe registered?
Safety comes first in all our work, which is why we maintain full Gas Safe registration – the UK's official gas safety certification.
You'll find our registration displayed prominently during every boiler maintenance visit, giving you complete peace of mind that your home is in qualified hands.
We've been proudly Gas Safe registered since 2002 (back when it was called CORGI), and we take this responsibility seriously.
It's not just a legal requirement – it's our commitment to keeping your family safe.
When we work on your boiler, you can rest assured that every aspect of the job meets strict safety standards.
We're your neighbours in Kent, and we treat every home we visit as if it were our own, applying our expertise with the utmost care and attention.
Our credentials can be easily verified through the Gas Safe Register website using our business ID number.

Common Boiler Problems In Gravesend
At Thames Boilers, we've seen just about every boiler problem you can imagine in Gravesend homes, from no hot water with working heating to those frustrating pressure drops that keep coming back.
We recognise how worrying it can be when your boiler starts acting up, especially when you see an unexpected fault code or hear strange banging noises.
Whether you're dealing with hot water that runs hot and cold or radiators that won't heat up, we're here to help identify and fix these common issues that affect many Gravesend households.
No hot water but heating is working
When your home has heating but no hot water in Gravesend, it often points to two main culprits: a faulty flow switch or a stuck diverter valve in combi boilers, or a malfunctioning motorised valve in conventional boilers.
While we don't offer emergency boiler services, we can help you understand what's happening.
Think of your boiler's diverter valve as a traffic controller – it directs hot water either to your radiators or your taps. When it gets stuck, you'll notice one system working but not the other.
Regular boiler maintenance tips include having your system serviced annually to prevent these issues.
If you're experiencing this problem, don't worry – it's a common issue we see in Gravesend, and our Gas Safe registered engineers can diagnose and fix it quickly.
Hot water is working, but radiators are not heating up
The frustration of cold radiators despite having hot water is a common winter headache for Gravesend homeowners.
We recognise how these radiator issues can leave you feeling chilly and confused about what's wrong with your heating system.
In our experience, when your hot water works but your radiators stay cold, there are a few likely culprits.
On combi boilers, it's often a stuck diverter valve causing these heating solutions to fall short.
For conventional boilers, a faulty motorised valve might be the problem.
But before you call us, here's a quick tip: check your programmer settings and room thermostat.
Sometimes, it's as simple as making sure your heating is actually set to come on and your thermostat is turned up high enough to trigger the system.
Boiler Pressure gauge keeps going down
Watching your boiler's pressure gauge steadily drop can signal costly underlying issues in your Gravesend home's heating system.
If you're noticing boiler pressure problems, we'll help you understand what's going on. Common causes we encounter include leaks in your system's pipes or radiators, which might be small but still problematic.
You'll often spot water dripping from the pressure relief valve outside your home – that's a telltale sign. Another culprit we frequently see is a faulty expansion vessel, which can't properly maintain your system's pressure.
Don't worry though – we're here to help! If you're experiencing dropping pressure in your Gravesend home, we'll track down the source and fix it properly.
These issues won't resolve themselves, so it's best to address them early.
Hot water on combi boiler runs hot and cold
Fluctuating between hot and cold water from your combi boiler is another frustrating issue we often see in Gravesend homes.
It's a common hot water issue that can make your morning shower feel like an unwanted adventure!
When your combi boiler performance isn't consistent, the culprit is usually a blocked plate heat exchanger.
Think of it like a clogged filter – it prevents your boiler from maintaining a steady hot water temperature.
If you're only experiencing this problem with your shower, though, don't worry too much about your boiler.
In that case, it's more likely to be a faulty shower cartridge that needs replacing.
We've helped many local homeowners tackle these exact problems, and we're here to help get your hot water running smoothly again.
There's a fault code on my boiler
Modern boilers often pop up with fault codes when something's not quite right – it's their way of telling you what's wrong.
While these codes might seem confusing at first, they're actually quite helpful for fault code troubleshooting and identifying the issue quickly.
When you see a common error displayed on your boiler's screen, don't panic! The best first step is to search online for your boiler make and the specific code (for example, "Vaillant F75").
This can give you a good idea of what's happening before you call us. Sometimes, it might be something simple that you can fix yourself, like low pressure, but other times it could indicate a more serious problem that needs professional attention.
Either way, we're here to help decode these mysterious messages and get your heating back on track.
Boiler is making a loud banging sound when it turns on
A loud banging noise from your boiler when it fires up is never a good sign – it's often called "kettling" and shouldn't be ignored.
When we hear about this type of boiler troubleshooting issue from our Gravesend customers, it usually means there's no proper water circulation in your system, causing it to overheat.
The most common culprit we find is a faulty pump that's not moving water through your system effectively.
However, it could also be trapped air in your pipes or a blocked main heat exchanger.
Whatever the cause, it's important to get this checked out quickly – that banging noise means your boiler's working harder than it should be, which could lead to more serious problems if left unchecked.

Frequently Asked Questions
What Should I Do if I Smell Gas Before the Engineer Arrives?
If you smell gas, let's keep you safe: immediately call the National Gas Emergency Service at 0800 111 999, open windows, don't use electrical switches, avoid naked flames, and evacuate the building until help arrives.
How Often Should I Get My Boiler Pressure Checked?
We recommend checking your boiler pressure monthly as part of regular boiler maintenance tips. The pressure gauge should read between 1-1.5 bar when cold. Regular monitoring helps prevent breakdowns and guarantees peak performance.
Can I Still Use My Hot Water if My Heating Isn't Working?
Yes, you can often still use hot water when your heating isn't working. It depends on your boiler type, as combi boilers operate these functions separately. We'd need to check your specific system to confirm this.
What's the Average Lifespan of a Domestic Gas Boiler?
We typically see modern gas boilers lasting 10-15 years with proper maintenance. Like us, you'll want to watch for signs like frequent breakdowns or rising bills indicating it's time for replacement. Regular servicing extends lifespan.
Should I Turn My Boiler off Completely While Waiting for Repairs?
We'd recommend keeping your boiler on unless there's a gas leak or visible damage. For your safety and home comfort, it's best to maintain minimal heating while waiting for repairs, following basic boiler shutdown precautions.
