Frequently Asked Questions
Have questions? We have answers. Here are some of the most common inquiries we receive from our clients.
How long does a new boiler installation typically take? +
A straightforward, like-for-like boiler swap (e.g., replacing an old combi boiler with a new one in the same location) can usually be completed within a single day. However, more complex installations, such as converting from a conventional system to a combi boiler, or relocating the boiler, may take two to three days. This is because it often involves significant changes to pipework, removal of old tanks, and making good on any structural alterations. We will always provide a clear and accurate timeline for your specific project during our home survey, ensuring minimal disruption and complete transparency.
What are the main types of boilers you install? +
We are experts in installing all three main types of modern gas boilers to suit any property and need. These include: Combi (Combination) Boilers, which provide heat and hot water on demand and are ideal for smaller homes; System Boilers, which use a hot water cylinder to supply multiple outlets at once, perfect for larger families; and Conventional (Regular) Boilers, which are suitable for homes with traditional heating systems and a high demand for hot water. Our home survey will determine the most efficient and practical solution for you.
How do I know what size (kW) boiler I need? +
Choosing the correct boiler size, or kilowatt (kW) output, is critical for efficiency and performance. It depends on several factors, including the number of radiators in your home, the number of bathrooms, your hot water usage patterns, and the property's insulation levels. A boiler that is too small will struggle to heat your home, while one that is too large will "cycle" (turn on and off frequently), wasting energy and causing unnecessary wear. Our certified engineers will perform a detailed heat loss calculation during the home survey to specify the exact kW output your home requires, ensuring optimal performance and maximum savings.
Is an annual boiler service really necessary? +
Absolutely. An annual service by a Gas Safe registered engineer is vital for three key reasons. Firstly, it ensures your boiler is operating safely, checking for any potential carbon monoxide leaks or combustion issues. Secondly, it maintains the boiler's efficiency, as the engineer will clean key components and make adjustments to ensure it's running at peak performance, which saves you money on fuel bills. Thirdly, and very importantly, it is a requirement to keep your manufacturer's warranty valid. Skipping a service can void your warranty, leaving you liable for the full cost of any repairs.
What brands of boilers do you work with? +
We are not tied to a single manufacturer. This independence allows us to recommend and install the best boiler for your specific needs and budget. We have extensive experience with all major, reputable brands known for their reliability, efficiency, and excellent warranties, including but not limited to Worcester Bosch, Vaillant, Ideal, Baxi, and Viessmann. We base our recommendation on performance data, customer feedback, after-sales support, and the specific requirements of your property, ensuring you get a high-quality product that will serve you well for years to come.
What is included in your free quote? +
Our free, no-obligation quote is comprehensive and fully transparent. It will include the cost of the new boiler itself, all necessary parts and fittings (such as the flue, filters, and controls), the labor cost for the installation by our certified engineers, the safe removal and disposal of your old boiler and any associated tanks, a full chemical flush of your heating system to ensure its cleanliness and efficiency, and the registration of your new boiler's warranty. There are no hidden charges; the price you see is the price you pay.
