    What Boiler Brands Do We Repair?

    Combi Boiler Repairs In Northfleet

    At Thames Boilers, we specialise in combi boiler repairs – a hot favourite among residents of Northfleet due to their snug fit in kitchens and sterling performance.

    The usual culprits our engineers encounter include:

    • Dodgy diverter valves
    • Pressure relief valve issues causing boiler pressure difficulties
    • Woes with the condensate pipe – prone to freezing during nippy conditions, causing the boiler to lock out.

    With our engineers in Northfleet, they’re specially qualified to spot and rectify these issues speedily, guaranteeing your combi boiler is up and running before you can utter ‘cor blimey!’

    Vaillant Boiler Repairs Northfleet

    Vaillant boilers are renowned for their quality, but like any boiler, they can experience issues over time. We often encounter faults such as not hot water and F75, F22, and F62 fault codes. At Thames Boilers we’re experienced in diagnosing and rectifying all such issues. Remember, if we can’t fix your Vaillant boiler, you only pay a small fee for the engineer’s visit.

    Ideal Boiler Repairs In Northfleet

    Ideal Boilers are widely used in homes across the UK for their reliability and efficiency. However, they can have occasional problems, such as issues with printed circuit boards, as well as the L1 and L2 fault codes. Our repair service covers these issues and more. We offer a standard boiler service free of charge (value £96) with all our fixed price boiler repairs for Ideal Boilers.

    Worcester Bosch Boiler Repairs Northfleet

    Worcester Bosch is indeed a name to reckon with in boilers due to their well-built nature. Yet there may arise situations when these stalwarts face issues such as clogged condensate traps, malfunctioning circuit boards or ignition glitches. Fret not, for our technicians in Northfleet are well-versed in managing such repairs and provide an efficient, fixed rate service. And for your peace of mind, any new parts we replace in the repair process comes with a year-long guarantee.

    Baxi Boiler Repairs Northfleet

    Renowned for their durability and effectiveness, Baxi boilers sometimes suffer common problems which we are equipped to solve. These could range from a defective auto-air vent causing pressure issues, to malfunctioning diverter valves or even a blockage in condensate pipes, mainly when the temperature drops. Our adept engineers at Northfleet have vast experience in detecting and mending faults in Baxi boilers. We only charge a small fee if we are unable to restore your boiler to its working condition.

    Potterton Boiler Repairs Northfleet

    While Potterton boilers are well-regarded in UK households, there can be ordinary issues like a problematic fan assembly or a glitchy printed circuit board. The specialized engineers at Thames Boilers are adept in addressing these repairs with exactness. On top of this, all replaced parts are backed by a 1-year guarantee, and if we can’t sort your Potterton boiler, a modest fee will apply for the engineer’s visit.

    Boiler Repair Questions & Answers

    How soon can you fix my boiler?

    It depends on the time of year and the weather.

    In the warmer months, we can usually attend on the same or next day, if it’s a working day.

    In the colder months, because it’s so busy, you may need to wait quite a lot longer for an appointment. Sorry.

    Can you fix my type of boiler?

    We can fix any boiler except oil boilers, LPG boilers, boilers rated over 70kW or those considered beyond economical repair. Other than that, we’ll do our best to fix it for you.

    Just bear in mind that we can’t fix some boilers under the fixed price repair offer. These will be charged at an hourly rate plus materials.

    Do I have to pay a callout fee?

    If your boiler is appropriate for a fixed fee boiler repair, no callout fee will be imposed.

    If not suitable for a fixed fee boiler repair, a minimum cost of 1 hour’s labour is necessary to have an engineer come out.

    What if I need a new boiler?

    On occasion, a boiler fix is seen to be not worth the price. This might be because the part necessary is hard to track down, or the expense to fix it is nearly as much as a new boiler. If this happens, we’ll make sure to tell you quickly and explain the need for a new boiler. We’ll also give you a complete written quote for a new one and allow you to make an informed decision about how to proceed. If you decide to let us handle the replacement of your boiler, we’ll do our best to make sure your new boiler is installed in a timely manner, generally within 48 hours.

    Boiler Servicing Questions & Answers

    Will servicing my boiler fix any faults or problems?

    No, this is a common misconception. The purpose of a boiler service is to check your boiler is working safely and carry out routine maintenance tasks. If your boiler isn’t working properly, a service won’t fix it.

    We recommend you contact us to book your fixed price boiler repair first. Then once the problem is fixed, you can book your boiler in for a service.

    Do I Need To Turn My Boiler Off Before It’s Serviced?

    Yes, if you can be without your boiler for a while, please turn the boiler off about 30 minutes before we arrive. This gives the boiler chance to cool down, ready for our performance tests.

    How Do I Check My Boiler Has Been Serviced Properly?

    There are 2 easy ways to tell if your boiler has been serviced properly:

    1. You should receive a service certificate either via email or as a paper certificate when your engineer has finished. This will contain details of all the checks carried out on your boiler.

    2. A standard service should take about 30-45 minutes to complete – and a full service should take between 60 and 90 minutes. If your service takes a lot less time than this, it may not have been completed properly.

    What Areas Do You Cover?

    We cover Northfleet, Kent and the surrounding areas, including Gravesend, Tilbury, Singlewell, Greenhithe, Swanscombe, Grays, Chadwell St Mary, Stone, West Thurrock, Cobham.
