A new boiler is a big investment, not just in cost, but in the comfort and safety of your home. Before committing to an installer, it’s important to ask the right questions. This ensures you’re getting a system that suits your needs and is fitted by someone you can trust. Here’s what you should ask before replacing your boiler.
Questions to ask before boiler replacement begins
Getting a clear picture of what to expect during and after installation can help avoid future headaches. From warranties to system compatibility, these questions will help you make an informed choice and get the best value from your investment.
Are you Gas Safe registered?
This should always be your first question. A Gas Safe registration means the installer is legally qualified to work with gas appliances. Ask for their registration number and verify it online for peace of mind. Never use an unregistered installer.
What type of boiler is right for my home?
Whether it's a combi, system, or regular boiler, the right model depends on your home's size, hot water demand, and existing pipework. A good installer will ask questions about your usage and assess your property to recommend the most efficient and cost-effective option.
Is my current system compatible?
If you’re upgrading from an older model or switching boiler types, ask if any components, like the flue, pipework, or thermostat, need replacing. It’s also worth checking if your radiators and controls are compatible with the new system for maximum efficiency.
What is included in the quote?
Make sure the quote covers all labour, parts, disposal of the old boiler, and VAT. Ask if it includes system flushing or a magnetic filter, which helps prolong the new boiler's life. A clear, itemised quote can help you avoid surprise costs later.
How long will the installation take?
Most replacements take a day or two, but factors like switching boiler type or upgrading the system could extend the timeline. Knowing how long your heating and hot water may be offline helps you plan ahead.
What aftercare or warranties are included?
Always ask about the length and coverage of the manufacturer warranty, and whether the installer offers any workmanship guarantee. Some boilers come with extended warranties if installed by an approved partner.
Will you register the warranty and notify Building Control?
In England, new boiler installations must be notified to Building Control. Your installer should handle this and register your warranty. Always request confirmation of both once the job is complete.
