Boiler Installation

Looking for a new boiler?  We specialise in fitting Worcester, Vaillant, Ideal, and Baxi boilers - with expert advice, quality workmanship, and no pushy sales tactics.

Is It Time for a New Boiler?

If your boiler is over 10-15 years old, you might be wasting money on rising energy bills and increasingly frequent repairs. Modern condensing boilers are far more efficient than older models, which means lower running costs and a more reliable heating system.

Beyond age, there are other signs it's time for a replacement. If your boiler is breaking down regularly, struggling to heat your home properly, making unusual noises, or the repairs are starting to add up, a new installation often makes more financial sense than patching up an old system. We'll assess your current boiler honestly and help you make the right decision – we'll never push you into a sale you don't need.

FAQs

Got questions about getting a new boiler installed? Here are answers to some of the most common queries we receive.

How much does a new boiler cost?

Boiler installation costs vary depending on the type of boiler, the size of your property, and the complexity of the installation. As a rough guide, combi boiler installations typically start from around £2,000-£3,000, whilst system and conventional boilers may cost more. We'll always provide a clear, fixed-price quote after assessing your property, so you'll know exactly what you're paying with no surprises.

How long does a boiler installation take?

Most straightforward boiler replacements take 1-2 days to complete. If you're switching boiler types (for example, from a conventional to a combi boiler) or significant pipework changes are needed, it may take longer. We'll give you an accurate timeframe when we survey your property and we'll always keep you informed throughout the process.

Which boiler brand should I choose?

We primarily install Worcester, Vaillant, Ideal, and Baxi boilers – all reputable manufacturers offering excellent reliability and warranties. The best choice depends on your property, budget, and heating requirements. We'll recommend the most suitable option based on what's right for you, not what earns us the highest margin.

Will I be without heating during the installation?

Yes, your heating and hot water will be off whilst we install your new boiler. However, we work efficiently to minimise disruption and will usually have your new system up and running by the end of the installation day. We'll always aim to complete the work as quickly as possible without compromising on quality.

What warranty comes with a new boiler?

All the boilers we install come with manufacturer warranties, typically ranging from 5 to 10 years depending on the brand and model. We'll register your warranty for you and provide all the necessary documentation. Remember, annual servicing is usually required to keep your warranty valid.
