Yes, a 20-year-old boiler should definitely be replaced. Most boilers have a lifespan of 10-15 years, so yours is well past its expected life. At this age, you’re likely experiencing reduced efficiency, higher energy bills, and increased breakdown risk. Modern boilers are 90%+ efficient compared to older models at 60-70%, meaning you’ll save significantly on heating costs.
A new gas boiler should be installed by a Gas Safe registered engineer who is qualified for the type of work required. C1 Boilers’ installation team handles the installation, commissioning and required safety checks, giving homeowners confidence that their new heating system has been professionally installed and checked before use.
Some boiler replacements can be completed as soon as the next day, depending on engineer availability, the boiler required and the complexity of the installation. C1 Boilers first assesses your heating requirements and recommends a suitable system before confirming the quote, installation requirements and earliest available installation date.
Your new boiler quote should clearly explain the boiler, installation work and heating-system preparation included in the price. Depending on your system, this may include flushing, controls, filter installation, commissioning and warranty registration. C1 Boilers assesses your existing heating system first so any required work can be included in your quotation.
Potential savings from a modern boiler depend on the efficiency and condition of your existing heating system, your property and how you use your heating. A correctly sized modern boiler combined with suitable heating controls can reduce wasted energy, but C1 Boilers assesses each home individually rather than promising the same saving for every household.
New boiler warranty length depends on the manufacturer, model and installation requirements. C1 Boilers offers manufacturer-backed warranties of up to 12 years on eligible installations. We’ll explain the warranty available with your recommended boiler, including any registration or servicing requirements needed to keep the manufacturer’s warranty valid.
The right boiler depends on your property size, existing heating system and hot-water demand. Combi boilers often suit flats and smaller homes, while system boilers may suit larger properties with multiple bathrooms. Regular boilers can suit homes retaining traditional systems. C1 Boilers assesses your property before recommending the appropriate type and output.
Eligible customers can spread the cost of a new boiler using available finance options, with repayment terms offered by C1 Boilers from 1 to 10 years. The available interest rate, deposit, monthly payment and total amount repayable depend on the finance product selected, installation cost and applicant eligibility.
