Gas Boiler Installation & Servicing in West Sussex & Hampshire
Reliable, Efficient Gas Heating — Installed and Serviced by Gas Safe Registered Engineers
Whilst our passion at Clean Heat Solutions lies in renewable heating technology, we understand that a gas boiler remains the right solution for many homes across West Sussex and Hampshire — whether as a like-for-like replacement, a temporary measure ahead of a future heat pump installation, or simply because it is the most practical option for your property right now. Our Gas Safe registered engineers carry out gas boiler installations and servicing to the highest standard, working with leading manufacturers including Vaillant and Viessmann to ensure your home benefits from a reliable, efficient, and correctly commissioned heating system. Whether you need a new boiler installed, your existing system serviced, or a fault diagnosed and repaired, Clean Heat Solutions delivers the same level of care, precision, and professionalism on every gas job that we bring to our renewable heating work.

Our Process
How It Works
Assessment & Recommendation
We begin by assessing your existing heating system, your property's heating demands, and your hot water requirements — giving you an honest, expert recommendation on the most suitable boiler make, model, and output for your home, with transparent pricing and no unnecessary upselling.
Installation & Commissioning
Our Gas Safe registered engineers carry out your boiler installation cleanly and efficiently, completing all necessary pipework, flue, and controls connections before commissioning the system fully in line with manufacturer specifications and current building regulations — including completion of the Benchmark commissioning checklist.
Aftercare & Annual Servicing
Once your new boiler is up and running, we recommend an annual service to keep it operating safely and efficiently, maintain your manufacturer warranty, and identify any potential issues before they become costly problems — and our team is always on hand if you need us between visits.
Benefits
Why Choose Gas Boiler Installation And Serving
Gas Safe Registered — Every Time
Every gas boiler installation and service we carry out is completed by a Gas Safe registered engineer — the legal requirement for anyone working on gas appliances in the UK, and your assurance that the work is safe, compliant, and fully certified.
Leading Brands, Properly Installed
We work with market-leading manufacturers including Vaillant and Viessmann — brands with outstanding reliability records and strong warranty support — and every boiler we install is commissioned fully to manufacturer specification, protecting your warranty and your investment from day one.
Honest Advice on Your Long-Term Options
As specialist renewable heating engineers, we are uniquely placed to give you an honest view of both your immediate gas heating needs and your longer-term options — so when you are ready to explore making the switch to a heat pump, you already have a trusted engineer who knows your home and your heating system inside out.
A well-installed and regularly serviced gas boiler is one of the most reliable forms of home heating available — and the difference between a boiler that performs consistently for fifteen or twenty years and one that causes repeated problems often comes down to the quality of the original installation and the consistency of its ongoing maintenance. At Clean Heat Solutions, every gas boiler installation is carried out strictly in accordance with Gas Safe regulations, manufacturer guidelines, and BS 7593:2019 water treatment standards — ensuring your system is safe, efficient, and fully warranted from day one. We also take the time to walk you through your new system controls, advise on the most efficient settings for your home, and ensure you are completely comfortable with how everything works before we leave. For homeowners across West Sussex and Hampshire who are considering their long-term heating options, we are also well placed to advise on the pathway from a gas boiler to a heat pump when the time is right — giving you a clear picture of what that transition would involve and what savings you could expect to achieve.
