Benefits of Servicing Your Boiler

We're passionate about helping you understand why regular boiler servicing isn't just another household chore - it's your ticket to a safer, more efficient home.
A well-maintained boiler will run more efficiently, cutting down those pesky fuel bills while keeping your family safe from potential gas leaks or carbon monoxide issues.
With over 25 years of experience in the heating industry, our team specializes in servicing all major domestic boiler brands including Worcester Bosch, Vaillant, and Baxi.
Keep your boiler safe
Taking care of your boiler isn't just about preventing breakdowns - it's about keeping your family safe and your energy bills low.
As your local Gas Safe engineers, we take boiler safety seriously and know exactly what to look for during our thorough inspections.
During our service visits, we check for potentially dangerous carbon monoxide leaks and guarantee your boiler's combustion is efficient and safe.
We'll test gas pressures, inspect the flue for proper ventilation, and make certain all safety devices are working correctly.
Plus, we'll clean essential components like the condensate trap and magnetic filter to prevent harmful buildup.
Think of boiler maintenance like a health check-up - it's better to catch small issues before they become serious problems that could put your family at risk.
With 25 years of experience in providing trusted heating solutions across Kent, our engineers deliver reliable and professional boiler servicing you can count on.
Save money on fuel bills
While energy costs continue to rise, a well-maintained boiler can actually help keep your fuel bills down. Our yearly servicing helps restore your boiler's combustion efficiency, which means you'll use less gas to heat your home and hot water.
Think of it like tuning up your car - when everything's running smoothly, you'll get better mileage.
During our standard service, we'll analyse your boiler's flue gases and check gas pressure to guarantee it's operating at peak fuel efficiency. We'll also clean crucial components like the magnetic filter and condensate trap, which can impact your system's performance.
Many of our customers notice cost savings on their energy bills after a professional service, making the £120 service fee a smart investment in the long run.
Installing smart heating controls can provide additional savings of up to 31% on your heating costs through automated temperature management and learning features.
Spot boiler problems early
Regular boiler servicing acts like an early warning system for your home's heating, helping catch small issues before they become expensive emergencies.
When we service your boiler, we're not just giving it a quick once-over - we're performing detailed checks that can reveal early boiler signs of trouble.
During our standard service, we'll analyse flue gases, check gas pressures, and inspect internal components for wear and tear.
We'll also test your system's water quality and look for any signs of sludge buildup.
This early detection approach means we can spot problems while they're still minor and manageable.
Think of it like a health check-up for your heating system - it's always better to find and fix small issues before they turn into major headaches.
Two Types of Boiler Service Available in Kent

We offer two main types of boiler services to meet your specific needs and budget in Kent.
Our Standard Service at £120 is perfect for newer boilers or those recently serviced, focusing on essential checks and basic maintenance.
For older boilers or those needing more attention, our extensive Full Service at £265 includes a thorough strip-down, deep cleaning, and detailed system evaluation to keep your heating running smoothly.
Standard Boiler Service
Thames Boilers offers two distinct service packages to keep your boiler running safely and efficiently.
Our Standard Service, at £120, is perfect for newer boilers under three years old or those that have received thorough maintenance recently.
During a Standard Service, we'll analyse your flue gases, check gas pressure and flow, and inspect all essential components.
We'll also clean your condensate trap and magnetic filter, test the expansion vessel pressure, and perform an internal gas leak test.
When we're done, you'll receive a digital service certificate right in your inbox.
For boiler maintenance tips, we recommend scheduling this service yearly.
It's the best way to guarantee peak performance, catch potential issues early, and keep your energy bills in check.
Plus, you'll have peace of mind knowing your boiler's being looked after by local experts.
Full Boiler Service
For older boilers needing extra care, our Full Service package at £265 delivers extensive maintenance that goes well beyond standard checks.
We'll remove and clean the burner, scrub the heat exchanger, and replace critical gaskets and seals to boost your boiler's energy efficiency.
Our thorough approach includes testing your system's water quality and bleeding all accessible radiators - essential boiler maintenance tips that help prevent future issues.
We'll even provide detailed written advice about any concerns we spot. Just like taking your car for a major service, this deeper level of care every 2-3 years helps protect your investment and keeps your heating running smoothly.
You'll get the same great digital booking experience and real-time tracking that our standard service customers enjoy.
Which Boiler Service Is Best For You?

Not sure whether your boiler needs a Standard or Complete Service? We'll help you make the right choice for your home.
For boilers under three years old, or those that have had a thorough strip-service in the past 2-3 years, our £120 Standard Service is perfect. It covers essential safety checks and basic maintenance to keep your system running efficiently.
However, if your boiler is older or hasn't had a deep clean recently, we'd recommend our £265 Complete Service. It's more extensive, including burner removal, heat exchanger cleaning, and system water testing.
Think of it as giving your boiler a complete health check - it's especially important for maintaining manufacturer warranties.
Let's keep your heating system safe and efficient with the right service level for your needs.

Frequently Asked Questions About Boiler Servicing in Kent

We recognise you've got questions about boiler servicing, and we're here to help clear things up.
As a Gas Safe registered company serving Kent since 2017, we've handled countless service inquiries and understand what matters most to homeowners.
From fault diagnoses to post-service guarantees, let's tackle some of your most common questions about boiler servicing in Kent.
My boiler has a fault - should I book a service?
When your boiler's acting up, it's tempting to book a service right away - but that's not actually the best first step.
A service is preventive maintenance, like an MOT for your car, and isn't designed to fix existing problems.
Instead, we recommend booking a fault diagnosis appointment. During this visit, we'll identify what's causing the issue and discuss repair options with you.
Think of it this way: you wouldn't book a regular car service if your engine warning light was on - you'd want the specific problem diagnosed first.
We're here to help you make the right choice for your situation. If your boiler's showing signs of trouble, let's start with finding out what's wrong, then we can plan the best course of action together.
If my boiler develops a fault after a service, do I need to pay for another visit?
Just like getting your car's MOT doesn't guarantee it won't develop issues later, a boiler service is a snapshot of your system's health at that moment in time.
While we thoroughly check and clean your boiler during a service, we can't predict or prevent future faults from developing. That's why, if your boiler develops problems after a service, you'll need to book a separate fault diagnosis visit.
Our service work doesn't include any ongoing guarantees against future breakdowns - it's focused on preventive maintenance and safety checks.
Think of it this way: your annual health check-up is important, but it doesn't mean you won't need to see the doctor if you get sick later. The same principle applies to your boiler's health and maintenance.
Are you Gas Safe Registered?
Absolutely yes - Thames Boilers has been Gas Safe registered since our founding in 2017, and owner George Lane has held his personal Gas Safe certification for over 25 years.
We take gas safety incredibly seriously, which is why we focus exclusively on domestic gas boilers.
Every job we complete, from servicing to repairs, follows strict Gas Safe protocols to keep your family protected. You'll always see us wearing our Gas Safe ID card, which proves we've passed the rigorous certification process required to work with gas appliances.
