Boiler Replacement: What You Need to Know

If your boiler is coughing, making strange noises, or just won’t heat your home, it might be time for a replacement. A new boiler can save you money on energy bills and keep the house comfortable all year round. Below we break down the basics – when to switch, how long the job takes, and what you’ll pay.

How Long Does a Boiler Replacement Take?

Most professional installers finish a full boiler swap in one day. The process starts with draining the old system, removing the old unit, and fitting the new one. After the hardware is in place, the installer tests the gas lines, checks for leaks, and calibrates the controls. If the existing pipework is in good shape, the whole job can be done in 6‑8 hours. Older homes with cramped spaces or outdated pipework may need extra time, but even then the work rarely stretches beyond two days.

While you wait, you can keep a portable electric heater handy for a few hours. It’s a small inconvenience compared to a cold house, and the installer will usually give you an estimate of the timeline before starting.

What Costs to Expect for a New Boiler

Price depends on the type of boiler, its efficiency rating, and the size of your home. A basic combi boiler for a small house starts around £1,200 – £1,500, including labor. For larger homes or high‑efficiency condensing models, the bill can climb to £3,000 or more. Most local companies, like Glastonbury Appliance Repair Services, offer a free quote and will walk you through the options.

Don’t forget to ask about warranties and service contracts. A good warranty (often 5‑10 years) can protect you from unexpected repair costs. Some installers also bundle an annual service, which helps keep the new boiler running smoothly.

When budgeting, consider any additional work that might be needed: replacing old pipework, upgrading the flue, or installing new controls. These extras can add a few hundred pounds but are worth it for safety and performance.

Ready to replace your boiler? Start by checking the age of your current unit – most boilers last 10‑15 years. If it’s older, or you’ve had repeated breakdowns, a replacement is the smart move. Call a local professional, get a quote, and ask about any government or utility rebates for high‑efficiency models. With the right boiler, you’ll enjoy steady heat, lower bills, and peace of mind for years to come.
