Modern boilers offer significant improvements in efficiency, reliability, and heating control compared to older models.
By upgrading your boiler, you can enjoy reduced energy bills, improved performance, and the peace of mind that comes with a manufacturer's warranty.

New A-rated boilers operate at over 90% efficiency, potentially saving you up to 30% on your heating bills compared to older models.

Modern boilers provide more consistent heating with fewer breakdowns, backed by manufacturer warranties for complete peace of mind.
We work with trusted boiler manufacturers to make sure you get a heating system that is reliable, efficient and built to last. By installing proven brands, we can recommend the right boiler for your home with confidence and give you peace of mind from day one.
We install boilers from leading names including Worcester Bosch, Ideal, Vaillant, Glowworm and Baxi. These manufacturers are well known for their quality, strong performance and dependable warranties, making them a popular choice for homeowners who want long-term value from their new boiler.
Each brand offers a range of models to suit different property types, heating demands and budgets. Whether you need a compact combi boiler for a smaller home or a more powerful system for higher hot water demand, we can help you choose a boiler that delivers the right balance of efficiency, comfort and reliability.
As experienced installers, we only recommend boilers we trust to perform well in real homes. Choosing one of these recognised brands means you benefit from modern energy-saving technology, consistent heating and hot water, and the reassurance of manufacturer-backed support.
The Vaillant Advance Extended Warranty offers extra peace of mind for your new Vaillant boiler. This enhanced, manufacturer-backed warranty is available for select boilers installed by an eligible Advance installer, protecting your boiler for longer.
The main benefit is extended coverage, providing reassurance and helping to reduce unexpected repair costs if a fault occurs. For example, installing a qualifying Vaillant boiler to the manufacturer's standards can grant you a longer warranty than the standard offering. This means more protection for your investment and greater confidence in your heating system.
At RCB Plumbing, we can advise if a Vaillant boiler and the Advance Extended Warranty are right for you. We'll explain your options, confirm eligibility, and perform the installation to the required standards, allowing you to access the warranty through us. It’s a simple way to enjoy reliable heating with the added security of extended cover from Vaillant.

Most standard boiler replacements take 1-2 days to complete. A straight replacement can often be completed in a single day, while system changes or relocations may require additional time.
This depends on your property size, hot water demands, and current system. Combi boilers work well for smaller homes with limited space, while system or regular boilers may be better for larger properties with higher hot water demands.
We handle the removal and environmentally responsible disposal of your old boiler as part of our service, ensuring all materials are recycled where possible.
With regular annual servicing, a quality modern boiler should last 10-15 years. We recommend joining our boiler care plan to ensure your new system operates at peak efficiency throughout its lifespan.
Our Warranty Booster Care Plan includes 2 years of complimentary servicing, priority breakdown response, and a dedicated helpline. It also helps retain your full manufacturer warranty.
