Boiler Installation in Gravesend, Kent

If your old boiler is starting to struggle or your energy bills are creeping up, it might be time for an upgrade. We provide professional, high-efficiency boiler installations for homeowners and businesses across Gravesend and the rest of the South East, keeping your home toasty and your energy costs right where they should be.

Boiler Replacement Across the South East

Upgrading your boiler is a major investment in your property’s comfort, safety, and monthly savings. We install a range of modern, high-efficiency systems specifically selected to fit your property type, your hot water demands, and your budget.

Every boiler installation we carry out in Gravesend and across the South East is fully Gas Safe certified, ensuring your home is in the most professional hands from start to finish.

Whether you’re replacing an aging unit that’s seen better days or you’re upgrading to a more efficient model to lower your bills, we don’t just “swap boxes”. As Vaillant-approved installers, we ensure your new boiler is perfectly configured and optimised to deliver reliable, high-performance heating for years to come.

The Heat Pump Grant: Save £7,500 on Your Upgrade

If you’re looking at a boiler replacement in Gravesend, it could be the perfect time to consider the Boiler Upgrade Scheme (BUS). As part of our mission to make low-carbon heating simple, we help Gravesend homeowners tap into government funding to swap their aging fossil fuel boilers for ultra-efficient air source heat pumps.

As MCS-accredited installers, Heatswap can help you claim a £7,500 government grant to offset the cost of a new heat pump system.

Signs It’s Time for an Upgrade

Most boilers last between 10 and 15 years. If yours is reaching that age, you might notice a few warning signs. It isn’t always about a total breakdown; it’s about efficiency. You should consider a boiler replacement if:

Your Energy Bills are Rising

Older boilers have to work much harder (and use more gas) to hit the same temperature compared to newer, modern boilers.

Frequent Repairs

If you’re calling out an engineer every winter, the repair costs can quickly overtake the price of a new, warrantied system.

Strange Noises

Banging or whistling usually means internal wear and tear that’s only going to get worse.

Slow to Heat Up

If your radiators are taking ages to get warm, your system is likely struggling and a replacement is likely needed.

Frequently Asked Questions

How many days does it take to fit a new boiler?

In most cases, a straightforward boiler swap takes between 1 and 2 days.

If we are upgrading your system or moving the boiler to a new location in your home, it might take a little longer. We always provide a clear timeframe before we start so you know exactly what to expect.

How long do boilers typically last?

Most modern boilers have a lifespan of about 10 to 15 years. However, this depends heavily on how well the system was designed and whether it has been serviced regularly.

If your boiler is over a decade old and starting to require frequent repairs, it is often more cost-effective to upgrade to a high-efficiency model rather than continuing to patch up the old one.

Do you offer any warranties on new boilers?

Yes. Because Heatswap is an approved installer for leading brands like Vaillant, we can offer extended manufacturer warranties that often reach up to 10 years.

This means you are fully covered for parts and labor, providing long-term peace of mind. Following the installation, we’ll ensure your warranty is fully registered for you.

Are you Gas Safe registered?

Absolutely. Safety is non-negotiable for us. We are fully Gas Safe registered, which is a legal requirement for anyone working on gas appliances.

Beyond that, we hold MCS, F-Gas, and MCIOB accreditations, ensuring that every aspect of our plumbing, heating, and renewable work meets the highest professional standards.

Should I get another boiler, or is it time for a heat pump?

This depends on your property and your long-term goals. While a modern gas boiler is highly efficient, The Heat Pump Grant now offers £7,500 towards switching to a low-carbon system, making it more affordable than ever to move away from gas.

As MCS-accredited designers, we can give you an honest appraisal of your home’s suitability for a heat pump, helping you weigh up the installation costs against future energy savings.
