An ageing, inefficient boiler rated D or E wastes fuel every hour it runs. Replacing it with a modern A-rated condensing boiler can cut your heating costs by up to £300 per year — paying for itself within a few years. A boiler installation is not a commodity purchase. The unit needs to be correctly sized for your property's heat demand, matched to your hot water usage patterns, and integrated properly with your existing pipework and controls. An undersized boiler struggles to heat your home. An oversized one short-cycles, wears out faster, and wastes energy. At Conroy Plumbing & Heating, we carry out a full heat-loss assessment before recommending a boiler. We factor in property size, insulation levels, number of bathrooms, and your family's usage patterns. This means you get exactly the right boiler — not the most expensive one on the van. We install boilers from Worcester Bosch, Vaillant, Baxi, Ideal, and other leading manufacturers. All installations are completed by Gas Safe registered engineers to current Building Regulations standards, and we handle the notification to your local Building Control on your behalf. ## Real Work Examples ## The Real Cost of Keeping an Old Boiler Running Boilers over 12 to 15 years old typically operate at 70-80% efficiency — meaning up to 30p of every pound you spend on gas is wasted. Modern A-rated boilers achieve 90%+ efficiency, delivering more heat from the same amount of fuel. Beyond higher bills, older boilers break down more frequently. Replacement parts become harder to source and more expensive. Each repair call-out adds to your total cost of ownership, and the risk of a complete failure during winter increases each year. An old G-rated boiler wastes up to £350 per year compared to a new A-rated model - Boilers over 15 years old have significantly higher carbon monoxide risk - Repeated repairs on an ageing boiler often exceed the cost of replacement within 2-3 years - Obsolete boiler models face parts shortages — a single failed component can mean weeks without heating - New-build regulations require condensing boilers — selling your home with an outdated system reduces property value ## Our Boiler Installation Process 1 ### Free Home Survey We visit your property to assess the current system, measure heat demand, discuss your hot water requirements, and recommend the right boiler type and size. This survey is free and carries no obligation. 2 ### Fixed-Price Quotation You receive a written quote covering the boiler unit, all materials, labour, gas and water connections, system flush, and Building Regulations notification. No hidden extras. 3 ### Professional Installation Most installations complete in one day. We remove your old boiler, install the new unit, connect all gas, water, and electrical supplies, fit new controls if required, and carry out a full system flush. 4 ### Commissioning & Testing We commission the boiler to the manufacturer's specifications, run a full gas safety check, test all radiators and hot water outlets, and verify the system is operating at peak efficiency. 5 ### Handover & Registration We register the warranty with the manufacturer, provide all documentation, submit Building Regulations notification, and walk you through the controls. Your new boiler is ready to run. ## Benefits of Choosing Conroy for Your New Boiler ### Correctly Sized Every Time We carry out a proper heat-loss calculation, not a guess. Your boiler matches your home's actual demand — avoiding short-cycling and energy waste. ### Manufacturer-Backed Warranty As approved installers, your boiler comes with the full manufacturer warranty — up to 12 years depending on the model and brand. ### Single-Day Installation Most straightforward boiler replacements are completed within one working day. We plan the work to minimise disruption to your household. ### Full System Flush Included Every installation includes a system flush to remove sludge and debris. This protects your new boiler and ensures maximum efficiency from day one. ### Building Regs Handled We notify Building Control on your behalf and provide the compliance certificate. One less thing for you to worry about. ### Aftercare & Servicing We offer annual servicing packages to maintain your warranty and keep your boiler running efficiently for years to come.

System boilers work with a hot water cylinder and suit larger homes with multiple bathrooms, providing strong flow to several taps simultaneously. Regular (conventional) boilers use both a cylinder and a cold water storage tank, and are the standard replacement for older gravity-fed systems. We assess your property and recommend the type that delivers the best performance for your household. ### Boiler Brands We Install We are experienced installers for Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann, and Glow-worm. Each brand has specific strengths — Worcester Bosch offers industry-leading warranties, Vaillant is known for build quality and longevity, and Baxi offers excellent value across their range. We recommend based on your needs, not our margin. ### Flue Routing and Positioning The flue must comply with current Building Regulations regarding distance from windows, doors, air vents, and boundaries. Vertical and horizontal flue runs have different maximum lengths depending on the boiler model. We plan the flue route during the survey to ensure compliance and optimal performance without unsightly external pipework. ### System Upgrades During Installation A boiler installation is the ideal time to address other system issues. We can add thermostatic radiator valves, upgrade the programmer to a smart thermostat, replace corroded pipework sections, install a magnetic filter to protect the new boiler, and add additional radiators if rooms are currently underheated. ### Condensate Drainage All modern condensing boilers produce acidic condensate that must be drained safely. We route the condensate pipe to an internal waste pipe where possible, or externally with lagging to prevent freezing. Incorrect condensate drainage is one of the most common causes of winter boiler breakdowns — we install it correctly the first time. ## Frequently Asked Questions ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">How much does a new boiler cost in Bolton? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">How long does a boiler installation take? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">What brand of boiler do you recommend? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Do I need to upgrade my radiators with a new boiler? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Will I need Building Regulations approval? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Do you offer finance for new boilers? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">What warranty do I get with a new boiler? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Can you move my boiler to a different location? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">What happens to my old boiler? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Do you install boilers in Manchester as well as Bolton?
