Boiler Upgrade Cost: What It Really Takes in 2025

When you're thinking about a boiler upgrade cost, the total price to replace an old gas boiler with a newer, more efficient model. Also known as boiler replacement cost, it's not just about the unit—it's about installation, permits, and whether you're switching to a different type of heating system altogether. Many people assume upgrading means swapping one boiler for another, but in 2025, the real question is whether you should even stick with gas at all.

That’s where heat pump, a system that pulls heat from outside air or ground to warm your home, using far less electricity than traditional boilers. Also known as air source heat pump, it's becoming the go-to alternative for UK homeowners looking to cut bills and meet environmental targets. The government’s Boiler Upgrade Scheme offers up to £7,500 off the price if you switch from gas to a heat pump, but it’s not free—you still pay the difference, which can range from £6,000 to £12,000 depending on your home. On the other hand, if you stick with gas, a new A-rated boiler typically runs between £2,000 and £4,000 installed, but that doesn’t include any extra work like new radiators or pipe upgrades.

What really drives the price? Your home’s size, how old your current system is, and whether your pipes or flue need fixing first. If your boiler broke down last winter and you’re now facing a full replacement, you’re probably looking at a bigger job than you thought. Some homes need new controls, thermostats, or even a power flush before the new unit goes in. And if you’re in a listed building or a tight urban space, installation gets trickier—and more expensive.

Don’t forget: a boiler upgrade isn’t just a repair. It’s a long-term decision. A new gas boiler might last 10–15 years. A heat pump can last 20+ years with minimal maintenance. If you’re planning to stay in your home for more than five years, the upfront cost often pays off in lower energy bills and fewer emergency repairs. That’s why so many people in Bognor Regis are now comparing quotes for both options side by side.

Below, you’ll find real-world breakdowns of what people actually paid for boiler replacements, what went wrong during installations, and how to avoid being overcharged. Whether you’re stuck with a broken gas boiler or weighing your options for something cleaner, these guides give you the straight facts—no sales pitch, just what works.
