Boiler Installation & Replacement in Bolton

Upgrading your heating shouldn’t be stressful. Our Gas Safe registered engineers in Bolton provide professional boiler installation and replacement, helping keep your home warm and energy efficient.

Boiler installations from £1,500 + VAT, depending on the boiler, system requirements and installation complexity.

3 Essential Reasons for Homeowners to Replace Their Boiler

If your current heating system is over a decade old or frequently breaks down, it is likely costing you more in repairs and wasted energy than a modern replacement.

Improved Energy Efficiency

Older boilers work much harder to produce less heat. A modern A-rated replacement converts almost all its gas into warmth, helping you significantly lower monthly energy bills in your Bolton home.

Total Safety and Compliance

Your family’s safety is our primary focus. Our Gas Safe engineers install new systems that meet the latest UK safety standards, removing the risks often associated with aging or faulty units.

Guaranteed Year-Round Reliability

Stop worrying about sudden breakdowns during a cold snap. A new installation provides modern reliability and long-term warranties, all backed by a local team that genuinely cares about your comfort.

How to spot an underperforming boiler in your home

Typically, these are the four signs that something is wrong with your boiler and it needs to be checked by a Gas Safe–registered engineer.

Strange or loud noises

If your system is making whistling or banging sounds it is often a sign of trapped air or internal debris. Our local Bolton team can quickly diagnose whether these noises are a minor fix or a symptom of a failing pump.

Uneven heating and cold spots

When your radiators take a long time to heat up or have cold patches it usually means your boiler is struggling to circulate water. This inefficiency causes your energy bills to rise unnecessarily in your home.

Frequent pilot light issues

A pilot light that keeps going out or burns with a yellow flame instead of blue is a serious warning sign. We recommend a Gas Safe inspection immediately to ensure your property remains safe and compliant with all UK standards.

Rising monthly energy costs

An underperforming boiler has to run for much longer to reach the same temperature which leads to a spike in monthly costs. We help local residents upgrade to efficient systems that provide more warmth for significantly less money.

 Trustindex verifies that the original source of the review is Google. We recently had a new boiler installed at our Bolton home in Ladybridge by Core Heat Plumbing Bolton and we’re really happy with it. They was friendly, explained everything clearly and didn’t try to upsell us on things we didn’t need. The job was done quicker than expected and everything was left clean and tidy after. Heating is working spot on now and the hot water pressure is loads better than before. Would definitely recommend them to anyone local needing a boiler installed.
