FAQ's

We get asked this question more than any other. This is why we created our instant online quotation tool, to help our customers get an instant quotation. The tool considers your needs and gives you a personalised quotation based on the information you have provided. If you have a specific boiler in mind please let us know and we can also quote you for this.

Generally, boiler replacement costs in Fife range from £1,800 to £3,500 for the unit itself, with installation included in our fixed-price quotes. The final cost depends on several factors including the type of boiler (combi, system, or regular), your property size, the complexity of your existing system, and whether any additional work is needed such as upgrades to pipework or controls.

Combi boilers are typically the most cost-effective option for smaller homes and flats, as they provide heating and hot water on demand without needing a separate cylinder. System and regular boilers may be more suitable for larger properties with multiple bathrooms or higher hot water demands.

We work with premium brands including Worcester Bosch, Navien, Baxi, Ideal, and Vaillant – all offering excellent reliability, efficiency, and manufacturer warranties. Our transparent pricing includes the boiler, all installation work, system flush, and commissioning. There are no hidden costs, no call-out fees, and no surprises. We can also discuss flexible payment options to help spread the cost if needed.

For most standard boiler replacements, we can typically complete the installation within 1-2 days from the date you book with us. In many cases, especially for straightforward combi boiler swaps, we can complete the entire installation in a single day, meaning you won’t be without heating and hot water for long.

The exact timeframe depends on several factors including the type of boiler being installed, whether you’re switching from one boiler type to another (for example, from a regular boiler to a combi), and whether any additional work is required such as relocating the boiler, upgrading pipework, or installing new controls.

For urgent situations where your existing boiler has broken down completely, we understand the stress this causes – especially during cold weather. We prioritise emergency installations and will work with you to schedule the replacement as quickly as possible, often within 2-3 days of your initial consultation.

Our process is straightforward: First, we conduct a free home survey or video consultation to assess your property and heating needs. We’ll then provide you with a fixed-price quote on the spot – no waiting around. Once you’re happy to proceed, we’ll book you in at a time that suits your schedule. Our fully qualified Gas Safe registered engineers arrive on time, work efficiently and tidily, and won’t leave until your new heating system is fully operational and you’re completely satisfied.

We also handle all the necessary paperwork including Building Regulations compliance certificates and manufacturer warranty registration, so you don’t have to worry about a thing.

Depending on which boiler you choose, they come with a 5, 7, 8 or 10-year Parts and Labour Warranty direct from the manufacturer. You can rest assured that your new boiler is in safe hands. If you have any problems we are here to help, and will be for the lifetime of your boiler.

Premium brands like Navien offer up to 10-year guarantees when installed by accredited installers like ourselves, while other quality manufacturers such as Worcester, Baxi, Ideal, and Vaillant provide generous 5-10 year coverage as standard. These warranties cover both parts and labour, meaning if anything goes wrong with your boiler during the warranty period, repairs are covered at no cost to you.

In addition to the manufacturer warranty, all our installation work is backed by our own professional 12-month workmanship guarantee. This covers any installation-related issues, ensuring that everything has been completed to the highest standard and giving you complete peace of mind.

To maintain your warranty, annual servicing is required – which we’re happy to provide. In fact, we offer convenient Home Cover Plans (Bronze, Silver, and Gold) that include annual servicing, priority call-outs, and various levels of boiler and heating system cover. This ensures your boiler stays in perfect working order year after year.

As Gas Safe registered engineers with extensive experience across all major boiler brands, we’ll be with you for the lifetime of your boiler. Whether you need routine servicing, emergency repairs, or just advice, we’re only a phone call away. You’re not just buying a boiler – you’re gaining a long-term relationship with a local, trusted heating company that genuinely cares about keeping you warm.

We understand that a new boiler is a significant investment, and we aim to make the payment process as straightforward and transparent as possible.

Payment options include:

Full Payment: You can pay the full amount upon completion of the installation by cash or bank transfer. We provide a clear, itemised invoice showing exactly what you’re paying for with no hidden charges.

Deposit and Balance: Many customers prefer to pay a deposit when booking the installation, with the remaining balance due upon completion. We’re happy to accommodate this arrangement, making it easier to plan your budget.

We always provide a fixed-price quote upfront, so you know exactly what you’re paying before any work begins. There are no call-out fees, no hidden charges, and no surprises. What we quote is what you pay – it’s that simple.

All our pricing is transparent and competitive. We believe in honest, fair pricing for quality work. You’ll receive a detailed breakdown of costs including the boiler unit, installation labour, any necessary materials, system flush, and commissioning – everything included in one clear price.

Our priority is keeping homes warm and safe with reliable, efficient heating systems. We work with customers to ensure the payment process is clear, fair, and manageable.


Please see our Google reviews for clarification as to who we are and what we stand for. We arrive on time, in company uniform, dedicated to ensure that you, the customer, are fully satisfied with the quality of our work.
