A modern A-rated boiler runs 92-94% efficient vs 60-70% for a 15-year-old unit — typically saving £250-400 a year on a 3-bed semi. An upgrade replacement (changing from heat-only to combi, or relocating the boiler) is a larger job but often a better long-term answer. We'll quote both options honestly so you can choose based on cost, performance and convenience. Every replacement includes a system flush (or power flush where required), a new magnetic filter, system controls upgrade where compatible, and full commissioning. You receive Gas Safe paperwork, building regulations notification, and manufacturer warranty registration on the day. ## Real Work Examples ## Signs Your Boiler Is Due for Replacement Boilers don't usually fail overnight — they decline. Watching for the warning signs lets you plan a replacement on your terms rather than panic-buying mid-winter when your heating dies. Boilers over 12-15 years old are usually beyond economic repair - Rising gas bills despite same usage usually mean falling efficiency - Repeated breakdowns or expensive repairs justify replacement - Old boilers running at 60-70% efficiency vs 92-94% for modern A-rated units - Boilers using R22 or other obsolete parts are increasingly hard to repair - Replacing during summer means no cold winter without heating ## Our Process 1 ### Survey Free home survey: assess existing system, hot water demand, radiator count, gas supply, flue routing. Honest recommendation on combi vs system vs heat-only. 2 ### Fixed Quote Detailed quote covering boiler, controls, flue, system flush, magnetic filter, removal of old unit, and all labour. No 'optional extras' added later. 3 ### Installation Typically 1-2 days. Old boiler removed and recycled, new boiler fitted, flue terminated correctly, gas tested, system flushed. 4 ### Commission Full commissioning to manufacturer spec — gas pressure, flue analysis, system balance, controls programmed. Building regulations notified. 5 ### Handover Full demonstration of the new boiler and controls, paperwork pack (Gas Safe, Benchmark, warranty registration, building regs certificate) handed over. ## Why Choose Conroy ### Up to 12-Year Warranty Worcester Bosch Greenstar and Vaillant ecoTEC offer extended warranties on like-for-like replacements when fitted by accredited engineers. ### A-Rated Efficiency 92-94% ErP efficiency — typically 25-35% lower gas bills than a 15-year-old non-condensing boiler. ### Finance Available Pay for your new installation in flexible monthly repayments through an introduction to TradeHelp Ltd.

You receive the building regs certificate within 14 days. ## Technical Detail ### Like-for-Like vs Upgrade A like-for-like swap (combi for combi, in the same location, same flue) is fastest and cheapest — usually 1 day. Changing type (heat-only to combi) or relocating adds 1-2 days but can improve performance significantly. ### Boiler Sizing Modern boilers should be sized by heat loss calculation, not just 'bigger is better'. An oversized boiler cycles on and off, reducing efficiency and component life. We calculate properly during the survey. ### Controls Upgrade Most replacements include a programmable thermostat upgrade. Smart thermostats (Nest, Hive, Honeywell) are available as an optional upgrade — see our smart thermostat service. ### Flue Considerations Modern condensing boilers produce a visible plume from the flue. We confirm flue location complies with current regulations and reroute where necessary using approved flue extensions. ### Warranty Registration We register your warranty on the day of installation. Annual servicing (by us or any Gas Safe engineer) is required to maintain the extended warranty — see our boiler servicing service. ## 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 boiler replacement cost? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">How long does the installation take? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Will you take my old boiler away? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Is finance available on a boiler replacement? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Is the new boiler covered by warranty?
