Gas Boiler Replacement in Essex & Hertfordshire

There are several signs that your gas boiler may need to be replaced. If it’s over 10–15 years old, breaks down frequently, or can’t deliver consistent heating and hot water, it may be more cost-effective to upgrade rather than continue with repairs. Other warning signs include strange noises, increasing energy bills, and difficulty sourcing parts for older models.

As an experienced heating company, Rothwells Heating can assess your current heating system and advise whether a new boiler installation would be more reliable and cost-efficient. Our Gas Safe registered engineers will guide you through your options and help you choose the best type of boiler for your home.

We also ensure the installation includes all necessary controls such as a room thermostat and thermostatic radiator valves, to help you manage comfort and efficiency. Replacing your old boiler with a modern, energy efficient one not only improves performance — it also helps lower your energy bills.

Upgrading to a new energy efficient boiler offers many benefits. Modern gas boilers are designed to use less fuel, meaning you’ll enjoy reduced monthly bills without compromising on performance. They also produce fewer emissions, lowering your home’s carbon footprint.

New systems come with advanced features like thermostatic radiator controls, programmers, and room thermostats, all of which help you better manage your heating and hot water usage. At Rothwells Heating, our Gas Safe engineers install these features as standard, ensuring your system is up-to-date and easy to control.

You’ll also gain greater reliability, with fewer breakdowns and less need for emergency boiler repairs services. And thanks to improved components and design, modern boilers are often quieter and more compact.

So whether you're experiencing regular faults or just want to future-proof your property, a new boiler installation is a smart investment for home comfort and long-term savings.

The cost of a boiler installation can vary depending on a number of factors: the type of boiler you choose (combi, system, or regular), the complexity of the job, and whether your existing heating system needs any upgrades. On average, prices range from £1,800 to £3,500+ for a standard gas boiler replacement in the UK.

At Rothwells Heating, we provide transparent quotes that include removal of your old boiler, expert installation by Gas Safe registered engineers, all required pipework and fittings, and a full system demonstration. We also ensure your system includes a thermostat and thermostatic radiator valves or a programmer and room thermostat to meet modern efficiency standards.

For peace of mind, we also offer manufacturer-backed warranties and guidance on ongoing boiler servicing to keep your system in top condition. If budget is a concern, ask about our finance options — we’re authorised and regulated by the Financial Conduct Authority to provide flexible payment solutions.

Every modern boiler installation includes advanced heating controls to help you manage your system efficiently. These controls typically include:

• A room thermostat that monitors temperature and adjusts the heating automatically.
• Thermostatic radiator valves that let you control heat in individual rooms.
• A programmer or programmable room thermostat, which lets you set heating schedules around your lifestyle.

At Rothwells Heating, we make sure your system includes the right combination of controls for optimal efficiency and ease of use. Our Gas Safe engineers will demonstrate how to use everything after installation so you’re confident in operating your new system.

These features are more than just convenient - they also help lower your energy usage and cut monthly costs. If you’re upgrading from an older gas heated system, you’ll be amazed at the difference smart controls and zoning can make to your comfort and bill savings.

Yes, even after a new boiler installation, regular boiler servicing is essential to maintain performance, safety, and warranty validity. Servicing helps catch issues early before they turn into expensive problems and ensures that your gas boiler continues to run as energy efficiently as possible.

At Rothwells Heating, we offer ongoing service plans tailored to your system and budget. Our Gas Safe registered engineers perform detailed inspections, clean components, and test for carbon monoxide leaks or other safety concerns.

Regular servicing not only extends the life of your heating system but also keeps you compliant with manufacturer requirements - especially important if your boiler is under warranty. If you experience any issues in between services, our boiler repairs service is just a call away.

We recommend booking a service once a year to ensure your boiler continues to run smoothly, efficiently, and safely - giving you peace of mind and long-term savings.
