The cost of a new boiler installation in London typically ranges from £1,800 to £3,500, depending on several factors: the type of boiler (combi, system, or regular), the brand and model you choose, the complexity of the installation, and whether any additional work is needed (like upgrading pipework or moving the boiler location). We provide free, detailed quotes that break down all costs clearly. Our prices are very competitive for London, and we never compromise on quality to offer cheap prices. Remember that a boiler is a long-term investment – choosing a quality installation now will save you money on repairs and energy bills for years to come.

The best boiler type depends on your specific circumstances. Combi boilers are ideal for smaller homes and flats with 1-2 bathrooms – they heat water on demand and don't need a storage tank, saving space. System boilers work well for larger homes with higher hot water demands and multiple bathrooms – they store hot water in a cylinder, ensuring good pressure for several taps/showers running simultaneously. Regular (conventional) boilers are best for homes with existing traditional heating systems or very high hot water demands. During our free consultation, we'll assess your property size, number of bathrooms, current system, and hot water usage patterns to recommend the perfect boiler type for your needs.

A straightforward like-for-like boiler replacement typically takes one day (6-8 hours) to complete. If you're changing boiler types (for example, converting from a regular boiler to a combi), it may take 2 days because we need to remove tanks, alter pipework, and potentially relocate the boiler. Complex installations involving significant pipework changes, new radiators, or difficult access may take 2-3 days. We'll give you an accurate time estimate during our initial assessment. We work efficiently to minimize disruption to your home, and we always aim to have your heating and hot water fully functional by the end of each day wherever possible.

Almost certainly yes! If your boiler is over 10 years old, a new modern condensing boiler will be significantly more energy efficient. Older boilers typically operate at 60-70% efficiency, meaning 30-40% of the energy (and your money) is wasted. Modern condensing boilers operate at 90-95% efficiency or higher, converting almost all fuel into usable heat. This can reduce your heating bills by 25-35%, depending on your current boiler's age and efficiency. Over the boiler's 10-15 year lifespan, these savings can amount to thousands of pounds. Additionally, modern boilers have better controls, allowing you to heat your home more precisely and reduce waste further. We'll calculate potential savings specific to your situation during our consultation.

Yes, we install all major boiler brands including Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann, Glow-worm, and others. We're not tied to any single manufacturer, which means we can recommend the best boiler for your specific needs and budget, rather than pushing whatever brand we have a deal with. Worcester Bosch and Vaillant are particularly popular for their reliability and comprehensive warranties. During our consultation, we'll discuss the pros and cons of different brands, warranty periods, and prices, helping you make an informed choice. We only work with reputable manufacturers whose products we trust, and we can source any specific model you prefer.

We handle all aspects of old boiler removal and disposal as part of our installation service. We'll carefully disconnect and remove your old boiler, along with any associated components like tanks or cylinders if you're changing system types. All materials are disposed of responsibly at licensed waste facilities, in accordance with environmental regulations. If your old boiler is particularly old, it may contain materials that require special disposal procedures, which we're fully qualified to handle. The removal and disposal costs are included in our installation quote – there are no hidden extra charges. You don't need to worry about any aspect of the old boiler; we take care of everything.

Absolutely. Our workmanship comes with a comprehensive 12-month guarantee, meaning if any issues arise from our installation work, we'll return and fix them free of charge. Additionally, the boiler itself will be covered by the manufacturer's warranty, typically ranging from 2-10 years depending on the brand and model (premium models often include longer warranties). We register every new boiler installation with the manufacturer to activate the warranty, and we provide you with all the documentation. We're also Gas Safe registered, which is a legal requirement for boiler installation, and we provide the mandatory Gas Safe certificate for your records. This certificate is often required by home insurance companies and is essential for legal compliance.

Yes, we can relocate boilers as part of an installation or as a separate service. Common reasons for moving a boiler include reclaiming space in a kitchen or bathroom, improving access for future servicing, or accommodating a home renovation. Relocating a boiler involves extending or rerouting gas pipes, water pipes, and the flue, which must all comply with building regulations and Gas Safe requirements. The cost depends on the distance of the move and the complexity of the new installation location (for example, external wall access for the flue). We'll assess your desired new location, check it's suitable and compliant, and provide a detailed quote. Relocating a boiler typically adds one day to the installation timeline.

A new boiler requires an annual service to maintain efficiency, safety, and warranty validity. Most manufacturer warranties are conditional on annual servicing by a Gas Safe registered engineer (like us). During an annual service, we inspect, clean, and test all critical components, check gas pressure and combustion efficiency, examine the flue and ventilation, and identify any potential issues before they become problems. Annual servicing typically costs £75-100 and can prevent costly breakdowns while ensuring your boiler runs as efficiently as possible. We offer reminder services so you never miss your annual service date. Beyond annual servicing, modern boilers are generally very reliable and shouldn't require additional maintenance.

Several government schemes may help with boiler replacement costs. The ECO4 (Energy Company Obligation) scheme helps low-income households and those receiving certain benefits upgrade to energy-efficient heating systems. The Boiler Upgrade Scheme offers grants for renewable heating systems like heat pumps (though not for traditional gas boilers). Some local councils offer additional support schemes. Eligibility depends on your circumstances, property type, and current heating system. We can provide information about current schemes and whether you might qualify, though you'll need to apply directly to the scheme administrators. Even without grants, the long-term savings from a modern efficient boiler often make it a worthwhile investment that pays for itself over time.
