Boiler installation FAQs
Quick answers about new boiler installation, boiler replacement, Gas Safe installers, warranties, installation timescales and fixed quotes across West London and North West London.
Ask on WhatsAppHow much does a new boiler installation cost?
A new boiler installation usually depends on the type of boiler, the size of your property, the complexity of the installation and whether any heating system upgrades are needed. We provide clear quotes before any work begins, so you know exactly what is included.
How long does a boiler installation take?
Most straightforward boiler installations can be completed within one day. More complex jobs, such as moving the boiler location, changing boiler type or upgrading pipework, may take longer. We will confirm the expected timescale before starting.
Do I need a Gas Safe engineer to install a boiler?
Yes. Gas boiler installation must be carried out by a Gas Safe Registered engineer. This helps make sure the boiler is installed safely, tested correctly and registered properly after installation.
What type of boiler do I need?
The right boiler depends on your property size, hot water demand, number of bathrooms, existing heating system and available space. Common options include combi boilers, system boilers and regular boilers. We can assess your home and recommend the most suitable option.
Can you replace my old boiler with a combi boiler?
Yes, in many properties an old boiler can be replaced with a modern combi boiler. This can free up space by removing stored hot water cylinders, but it depends on your water pressure, property size and hot water usage.
Will my new boiler come with a warranty?
Yes, most new boilers come with a manufacturer warranty, but the warranty length depends on the boiler brand and model. To keep the warranty valid, the boiler usually needs to be installed by a qualified engineer and serviced annually.
Do you remove the old boiler?
Yes. As part of a boiler replacement, we can remove the old boiler and leave the work area tidy. We will explain what is included in your quote before the installation is booked.
