If your boiler is unreliable, inefficient or beyond economical repair, it may be time to consider a boiler replacement. An ageing boiler can lead to higher energy bills, repeated breakdowns and inconsistent heating, particularly during colder months in Berkshire.
At Alliance CFM, we provide professional boiler replacement and installation services across Reading, including RG30 and surrounding postcodes. Our Gas Safe registered engineers install efficient, reliable heating systems tailored to your property and heating needs.
This page explains when to replace your boiler, what the process involves and what to expect from a professional installation.
When Should You Replace Your Boiler
Many homeowners search for signs you need a new boiler or when to replace a boiler. Here are the most common indicators:
Your boiler is over 12 to 15 years old
Older boilers are far less efficient than modern condensing models. Even if they still function, they often waste energy and cost more to run.
Frequent breakdowns and repairs
If you are calling an engineer regularly, repair costs can quickly add up. At a certain point, investing in a new boiler becomes more sensible than continuing to repair an unreliable one.
Rising energy bills
A decline in efficiency often leads to higher gas consumption. Modern A-rated boilers are designed to use less fuel while providing consistent heating and hot water.
Inconsistent heating or hot water
If some radiators never fully heat up or hot water runs out quickly, your system may no longer be suitable for your household’s needs.
Parts are difficult to source
Manufacturers eventually discontinue older models. If replacement parts are scarce, a full boiler replacement is often the most practical solution.
The Boiler Replacement Process
Many homeowners search for how long does a boiler replacement take or what happens during boiler installation. Here is what you can expect:
Initial assessment and quotation
We visit your property to assess your current system and heating requirements. You receive clear recommendations and a straightforward quotation.
Removal of the old boiler
The existing boiler and any redundant components are safely removed and disposed of correctly.
System upgrades if required
This may include flushing the heating system, upgrading pipework, fitting new controls or adjusting flue positions.
Installation of the new boiler
Your new boiler is installed in line with Gas Safe regulations and manufacturer requirements.
Testing and commissioning
We test the entire system thoroughly to ensure safe operation, correct pressure levels and optimal efficiency.
Handover and advice
We explain how to use your new controls and thermostat to maximise efficiency. Most standard boiler replacements are completed within one to two days, depending on complexity.
Can You Replace a Boiler in the Same Location
Yes and in many cases this is the simplest option. Keeping the boiler in the same position reduces installation time and complexity. However, some homeowners choose to relocate the boiler to improve space or layout. Our engineers will advise on feasibility and regulatory requirements.
