New Boiler Installation By Gas Safe Engineers

A new boiler installation in Bournemouth and Poole typically ranges from £1,500 to £3,500, depending on the type of boiler, the complexity of the installation, and whether any pipework changes are needed. Combi boiler replacements on a like-for-like basis are generally at the lower end, while full system upgrades or first-time installations sit higher.

A standard like-for-like combi boiler replacement typically takes between 4 and 8 hours and is completed in a single day. More complex installations, such as switching from a conventional system to a combi, or fitting a system boiler with a new cylinder, may take 1 to 2 days. We aim to cause minimal disruption, and our engineers will give you a clear time estimate before any work begins.

The best boiler type depends on your home's size, hot water demand and existing pipework. Combi boilers are ideal for smaller homes with one bathroom, as they provide instant hot water directly from the mains with no cylinder needed. System boilers suit homes with higher hot water demand and work with a storage cylinder. Conventional (heat-only) boilers are best for older properties with existing tank systems. We assess your property and recommend the most suitable option before any installation is carried out.

Yes. By law in the UK, all gas boiler installations must be carried out by a Gas Safe registered engineer. Installing or connecting a gas appliance without Gas Safe registration is illegal and dangerous, and could invalidate your home insurance. All of our engineers are fully Gas Safe registered, so every installation is safe, compliant and properly certified on completion.

We handle the full removal and responsible disposal of your old unit as part of the service. We disconnect and decommission the existing boiler safely, remove it from the property, and make sure all gas connections are properly sealed before fitting the new system. You do not need to arrange separate disposal — it is all included.

Yes. We install Viessmann boilers, which come with up to a 10-year manufacturer's guarantee, including protection against corrosion on the stainless steel heat exchanger. To keep the warranty valid, the installation must be carried out by an approved contractor — which we are — and the system must be in a clean condition. We include a system check as part of every installation so the warranty is valid from day one.

Yes, and it is often a legal necessity. If a boiler in a rental property is beyond repair or unsafe, landlords are legally required to make sure tenants have a working heating and hot water system. We install new boilers in rental and landlord-owned properties across Bournemouth and Poole, and can also provide a Gas Safety Certificate (CP12) following installation to meet your legal obligations.

In most cases, yes. Leading boiler manufacturers including Viessmann require the heating system to be clean before a new boiler is fitted, otherwise the warranty may be invalidated. Sludge and debris in old pipework can damage a new boiler within months. We assess the condition of your system during the pre-installation survey and will recommend a power flush if it is needed, which can be carried out as part of the same visit.
