What We Cover
Why Boiler Servicing Matters
Our Servicing Process
**Book Your Annual Service** - We recommend booking your boiler service during the summer months when demand is lower, ensuring your heating system is ready for winter. You can book online at booking.thamesboilers.co.uk or call us on 01322 788 418. We'll arrange a convenient appointment time.
**Pre-Service Notification** - You'll receive a confirmation email with your appointment details. On the day of your service, we'll send you a text message when your engineer is on the way, plus a tracking link so you know exactly when to expect us - no more waiting around all day.
**Visual Inspection & Safety Checks** - Our Gas Safe registered engineer will start with a thorough visual inspection of your boiler, checking for signs of corrosion, leaks, or damage. We'll examine the flue, check ventilation is adequate, and ensure the area around your boiler meets safety requirements.
**Internal Component Testing** - We'll open up your boiler and inspect internal components including the heat exchanger, burner, ignition system, and safety devices. We'll test the flame picture, check gas pressure, and verify that all sensors and controls are working correctly.
**System Performance Tests** - We'll test your boiler under operating conditions, checking combustion efficiency, flue gas analysis, and overall performance. This tells us if your boiler is running as efficiently as it should or if adjustments are needed.
**Cleaning & Adjustments** - We'll clean the burner, check and clean the condensate trap, and make any necessary adjustments to optimise performance. If we identify any worn parts that may need replacing soon, we'll advise you so you can plan ahead.
**Gas Safety Certificate & Service Report** - After completing your service, you'll receive an official Gas Safety Certificate (CP12 for landlords) and a detailed service report. We'll explain any findings and recommendations, and update your digital service record for future reference.
Common Servicing Issues We Fix
Carbon Monoxide Safety Concerns
During servicing, we test for carbon monoxide leaks using specialist detection equipment. Carbon monoxide is a silent killer - colourless, odourless, and deadly. Issues can arise from incomplete combustion, blocked flues, or faulty seals. A service identifies these potentially life-threatening problems before they put your family at risk.
Reduced Efficiency & Higher Bills
Over time, boilers lose efficiency as components wear, burners get dirty, and settings drift from optimal. During a service, we measure combustion efficiency and can often improve performance through cleaning and adjustment. Many customers notice lower energy bills after a service as their boiler runs more efficiently.
Wear & Tear on Key Components
Boilers work hard, especially during winter, and components naturally wear over time. During a service, we inspect parts like pumps, valves, heat exchangers, and seals. By identifying worn components early, we can advise when replacement might be needed, allowing you to budget and avoid an unexpected breakdown at the worst possible time.
Pressure Problems & Leaks
We check your system pressure and look for small leaks that might not be obvious to homeowners. Slow drips from valves or pipe connections can cause pressure to drop over time, affecting heating performance. Catching these early prevents larger leaks and water damage to your property.
Obsolete or Unsafe Installations
Building regulations and safety standards change over time. During a service, we'll check that your boiler installation still meets current standards. If we find anything that doesn't comply - such as inadequate ventilation, incorrect flue termination, or missing safety devices - we'll advise on the necessary remedial work to bring your installation up to standard.
Warranty Invalidation
Many homeowners don't realise their boiler warranty requires annual servicing by a qualified engineer. Without proof of regular services, manufacturers can refuse warranty claims, leaving you to pay for expensive repairs. We keep digital records of all services we carry out, ensuring you have the documentation needed if you ever need to make a warranty claim.
Boiler Servicing Pricing
We offer two levels of boiler servicing to suit different needs and budgets. Our Standard Boiler Service at £120 covers all essential safety checks, performance testing, and basic maintenance - perfect for most homeowners. For those wanting the most thorough service possible, our Full Boiler Service at £265 includes everything in the standard service plus a comprehensive system inspection, power flush if needed, and complete system optimisation. Both services include a Gas Safety Certificate, and all prices include VAT with no hidden extras.
Standard Boiler Service
Full Boiler Service
All prices include VAT and a Gas Safety Certificate. Landlords requiring a CP12 certificate should book our Standard Service as a minimum. Any additional parts or repairs needed will be quoted separately. If you have an unvented cylinder, ask about our combined service packages.
Frequently Asked Questions
How often should I have my boiler serviced?
We recommend annual boiler servicing, ideally in the late summer or early autumn before the heating season begins. This ensures your boiler is working safely and efficiently when you need it most during winter. Annual servicing is also typically required to maintain manufacturer warranties and is a legal requirement for landlords on rental properties.
What's the difference between your Standard and Full service?
Our Standard Boiler Service (£120) covers all essential safety checks, combustion analysis, visual inspection, and basic maintenance - everything required for a Gas Safety Certificate and to meet warranty requirements. Our Full Boiler Service (£265) includes everything in the standard service plus a comprehensive system inspection, chemical treatment to prevent corrosion, radiator balancing, and complete system optimisation for maximum efficiency and performance.
Do you provide a Gas Safety Certificate?
Yes, all our boiler services include an official Gas Safety Certificate (also known as a CP12 for landlords). This certificate confirms that your gas appliances have been checked and found to be safe. Landlords are legally required to provide tenants with a copy of this certificate within 28 days of the inspection. We provide the certificate immediately after completing your service.
I'm a landlord - can you service all appliances in my rental property?
Absolutely. As well as boiler servicing, we can inspect and test all gas appliances in your rental property including gas cookers, fires, and water heaters. This comprehensive gas safety check ensures you meet your legal obligations as a landlord. We'll provide a CP12 certificate covering all appliances tested, and we can set up annual reminders so you never miss your legal requirement.
What happens if you find a problem during the service?
If we identify any issues during your boiler service, we'll explain the problem clearly and advise on the best course of action. For minor adjustments or small repairs that can be done immediately, we'll discuss options with you. For larger repairs requiring parts, we'll provide a separate quote. We'll always advise on the urgency - whether it's a safety concern that needs immediate attention or something to plan for in the future.
Can you service my boiler if it wasn't installed by you?
Yes, we service all makes and models of boilers regardless of who installed them. Our engineers have experience with all major brands including Worcester Bosch, Vaillant, Ideal, Baxi, and many others. We follow manufacturer service schedules and have access to technical information for all common boiler types.
Will servicing really save me money on energy bills?
A well-maintained boiler runs more efficiently, and many customers do notice lower energy bills after a service. While we can't guarantee specific savings (as they depend on usage and other factors), cleaning the burner, optimising combustion, and ensuring your system is running as the manufacturer intended typically improves efficiency. Industry estimates suggest a properly serviced boiler can be up to 10% more efficient than a neglected one, which adds up over a heating season.
