Got some questions about servicing your new boiler or got one that’s begging for some TLC? You’re in the right place, BoilerBooker makes boiler servicing easy and affordable.

Whether you’ve got a trusty old boiler, a hot water cylinder, or a mysterious HIU that you pretend to understand, we help homeowners save time, money, and hassle by booking annual services together. This page answers all your burning questions, from why servicing matters to how to organise a group boiler booking for your street — so you can stay warm, safe, and smug knowing it’s all sorted.

 

  • BoilerBooker is a marketplace for independent local plumbers and heating engineers to provide annual boiler and hot water cylinder services at a lower cost for customers. We group the bookings on behalf of the heating engineer. The service is provided by the local heating engineer. Please read the Terms & Conditions here.

  • Think of it as a carpool for your heating engineer.
    When you and your neighbours book your annual boiler service together, the engineer makes one efficient trip instead of five separate ones. That means less travel, lower costs, and fewer scheduling headaches.

    With group boiler servicing, you:

    • Share call-out fees

    • Reduce engineer travel time (and emissions!)

    • Get priority slots for your block or street

    • Enjoy that smug, organised feeling knowing it’s all sorted

    BoilerBooker makes this easy — just set up your group, pick a date, and let us handle the rest. Fewer clicks, fewer cold showers.

  • It’s like the difference between a kettle, a water tank, and a mini power station – all keeping your home toasty in different ways.

    • Boiler: Heats water for your taps and radiators. Needs a yearly check to keep it safe and efficient.

    • Cylinder: Stores hot water for later use (common in larger homes). Needs servicing to prevent scale, leaks, and inefficiency.

    • HIU (Heat Interface Unit): Found in blocks of flats connected to a communal heating system. It’s the “middleman” that transfers heat from the network to your flat — and yes, it needs annual servicing too.

    Each system plays its part and BoilerBooker helps you book the right engineer for all three. At a low cost.

  • Easy: gather your neighbours, not their boiler manuals.

    Here’s how it works:

    1. Book a date via BoilerBooker for your building, street, or estate.

    2. Share the link — invite your neighbours (Facebook and WhatsApp groups work wonders).

    3. Sit back — our system coordinates the engineer visits.

    The more households that join, the more everyone saves. It’s local teamwork that actually pays off (and keeps everyone warm).

  • Because your boiler’s a quiet hero and even heroes need a check-up.

    An annual boiler service:

    • Catches small issues before they become expensive disasters

    • Keeps your system safe (no one likes surprise gas leaks)

    • Maintains efficiency and lowers bills

    • Keeps your warranty valid

    Skipping it is like skipping oil changes on your car – it might work fine… until it doesn’t.
    With BoilerBooker, you can book your service in under a minute and never forget again.

  • Let’s break down the “I’ll do it later” logic:

    • Breakdowns: The average repair costs £200–£500. A BoilerBooker annual service is £70 or under.

    • Efficiency loss: A neglected boiler can waste 10-20% more energy.

    • Safety risks: Undetected leaks or carbon monoxide issues can be dangerous.

    • Voided warranties: Most manufacturer warranties require annual servicing.

    So, skipping your service doesn’t really save money – it just postpones the bill (and makes it bigger).
    A yearly booking through BoilerBooker keeps your boiler and your wallet, healthy.

  • We turn “Who’s booking the heating engineer this year?” into a one-click solution.

    Residents’ associations can:

    • Create a group booking for their block or estate

    • Invite residents via link or email

    • Set a servicing window that suits the whole community

    • Track who’s confirmed and view all certificates in one place

    No spreadsheets. No chasing. Just smooth, shared servicing that saves time, money, and stress for everyone.
    It’s community coordination, finally made easy.
