Central Heating Installation in Worthing

Central heating installation in Worthing covers new radiator systems, extending heating into an extension or converted room, and full system upgrades. Any work involving the gas side of a boiler must be carried out by a Gas Safe registered engineer, and getting the system properly balanced across every room matters as much as the boiler itself.

    Our Expertise

    A heating system that actually balances across the whole house

    A central heating installation is only as good as how evenly it heats every room it's connected to - undersized radiators, poorly routed pipework, or a system that isn't balanced properly can leave some rooms cold while others overheat, even with a perfectly good boiler doing the work. Planning radiator sizes and pipe runs around the actual rooms, not just adding radiators wherever's convenient, is what makes the difference. Any work on the gas side of the system must be carried out by a Gas Safe registered engineer - always check registration before booking.

    What's involved in installing a new central heating system, and why does a Gas Safe registered engineer need to be involved?

    A full installation typically includes the boiler, radiators sized for each room, pipework and a control system - and anything touching the boiler's gas supply legally requires a Gas Safe registered engineer.

    Beyond the boiler itself, radiator sizing is worked out room by room based on the space and its heat loss, not applied as a single standard size throughout. Pipework routing needs to reach every radiator sensibly, and a control system - thermostat, timer, and increasingly smart heating controls - ties the whole system together so it runs efficiently rather than just heating everything at once. The pipework and radiators themselves aren't gas work, but anything touching the boiler's gas supply or connections is, and that legally requires a Gas Safe registered engineer - always check registration on the official Gas Safe Register before any gas-related part of the installation begins.

    Can I extend my existing heating system into a new room or extension?

    Usually yes, but it depends on whether the existing boiler and pipework have enough capacity to take the extra load without affecting heating elsewhere in the property.

    Adding radiators to an extension or a converted room is a common request, but it's worth checking the existing boiler's output and the pipework's capacity before assuming it'll simply cope with the extra load. If your boiler is already older or has been struggling, this is also a reasonable moment to check whether it's worth extending the current unit's working life or planning for a replacement.

    Frequently asked questions

    How long does a central heating installation take?

    Adding a radiator to an existing system is usually a short job, while a full system installation across a property takes considerably longer, particularly where pipework needs to be routed through multiple rooms. A survey gives a realistic timeframe.

    Will a new radiator affect heating in the rest of the house?

    It can, if the existing boiler and pipework are already close to capacity - this is worth checking before adding significant extra radiator load to an older or smaller system.

    Do I need a Gas Safe registered engineer for radiator work?

    Radiator and pipework installation itself isn't gas work, but anything connecting to or affecting the boiler's gas side must be carried out by a Gas Safe registered engineer - always check registration before any gas-related work starts.

    Can smart heating controls be added to an existing system?

    In most cases yes, though compatibility depends on the existing boiler and wiring - worth discussing at survey stage alongside any wider heating work.
