A faulty diverter valve, a worn pump, a failed PCB, or a blocked heat exchanger can stop your boiler dead. But with the right diagnosis, these are straightforward repairs that extend your boiler's life by years. The problem is that many companies default to recommending replacement because it is more profitable. At Conroy Plumbing & Heating, we diagnose first, explain honestly, and repair wherever it makes economic sense. If a repair is not worthwhile, we will tell you — and explain exactly why. We repair all major boiler brands including Worcester Bosch, Vaillant, Baxi, Ideal, Potterton, Glow-worm, and more. Our vans carry the most commonly needed parts, so most repairs are completed in a single visit. All work is carried out by Gas Safe registered engineers. Every repair includes a full safety check to ensure your boiler is operating correctly and safely before we leave. ## Real Work Examples ![Vaillant ecoTEC pro 28 boiler with copper pipework during repair inspection](/images/work-16.jpg) ## Why Delaying a Boiler Repair Costs You More A boiler displaying error codes, making unusual noises, or losing pressure intermittently is telling you something is wrong. Ignoring these warning signs does not make the problem go away — it makes it worse and more expensive. A minor fault that costs £80 to fix today can cascade into a major failure costing £400+ next month. A slowly failing pump puts strain on the heat exchanger. A leaking valve corrodes internal components. Early intervention is always cheaper. - Intermittent pressure loss often indicates a failing expansion vessel or slow leak — both worsen over time - Strange noises like kettling, banging, or whistling signal limescale build-up or trapped air damaging components - Boilers locking out repeatedly can indicate a flue blockage, which poses a carbon monoxide risk - Running a boiler with a known fault can void your warranty and invalidate your insurance - Families with children, elderly, or vulnerable members cannot afford to lose heating during winter ## Our Boiler Repair Process 1 ### Phone Assessment Call 07863 789484. We will ask about symptoms, error codes, and your boiler make and model. In many cases, we can narrow down the likely fault before arriving. 2 ### Diagnostic Visit We test the boiler systematically — checking gas pressure, flue readings, electrical connections, water pressure, and component function. We identify the root cause, not just the symptom. 3 ### Clear Explanation & Price We explain what has failed and why, show you the faulty component where possible, and give you a fixed price for the repair. If the repair is not economical, we tell you honestly. 4 ### Same-Day Repair If we carry the part — and we usually do — we complete the repair immediately. For specialist parts requiring ordering, we typically return within 24-48 hours. 5 ### Safety Check & Handover Every repair includes a gas safety check. We verify the boiler is operating correctly, check for carbon monoxide, and confirm all safety controls are functioning. ## Why Choose Conroy for Boiler Repairs ### No Fix, No Fee Diagnostics If we cannot identify the fault, you do not pay for the diagnostic visit. We stand behind our ability to find the problem. ### Same-Day Repairs Available Most common faults are fixed on the same day. We carry a comprehensive stock of parts on every van. ### All Makes and Models Worcester Bosch, Vaillant, Baxi, Ideal, Potterton, Glow-worm — whatever brand you have, we can diagnose and repair it. ### Honest Repair-or-Replace Advice We will never push a new boiler when a £100 repair will solve the problem. Equally, we will not waste your money patching a boiler that is beyond economic repair. ### Parts & Labour Guarantee All repairs are guaranteed on both parts and labour. If the same fault recurs, we return and fix it at no additional cost. ### Gas Safe Registered Every repair includes a safety check. You can trust that your boiler is operating safely and legally after we leave. ## Boiler Repairs: What You Need to Know ### Common Boiler Faults We Fix The most frequent boiler repairs we carry out include faulty diverter valves (causing no hot water but heating works), failed pumps (no circulation, cold radiators), PCB failures (boiler will not ignite or displays error codes), blocked or leaking heat exchangers (kettling noise, pressure loss), faulty gas valves (boiler locks out on ignition), broken thermistors and sensors (erratic temperatures), expansion vessel failure (frequent pressure loss), and fan faults (boiler will not start). ### Understanding Boiler Error Codes Modern boilers display fault codes that help pinpoint the problem. For example, Worcester Bosch EA fault codes indicate an ignition failure, Vaillant F28 codes indicate a failed ignition attempt, and Baxi E133 points to a gas supply issue. We are familiar with the fault code systems of all major manufacturers and can often diagnose the likely cause before arriving at your property. ### Boiler Pressure Problems If your boiler keeps losing pressure, the cause is either a water leak somewhere in the system (often at radiator valves or pipe joints) or a failed pressure relief valve or expansion vessel within the boiler itself. We systematically check each possibility to find and fix the actual cause — not just top up the pressure and leave. ### When Repair Is Not Worth It We recommend replacement over repair when the cost of repair exceeds 50% of a new boiler installation, when the boiler is over 15 years old with multiple recent failures, when parts are no longer manufactured, or when the boiler's efficiency has degraded to the point where a new installation would pay for itself within 2-3 years through energy savings. ### Preventative Maintenance After Repair After completing a repair, we often recommend an annual service to catch future issues early. We can also fit a magnetic filter to trap system debris before it reaches the boiler, significantly reducing the risk of future heat exchanger and pump failures. ## Frequently Asked Questions ### How much does a boiler repair cost in Bolton? ### Can you repair my boiler today? ### Do you repair all boiler brands? ### What does 'no fix, no fee' mean? ### My boiler keeps losing pressure — what causes this? ### Is it worth repairing a 15-year-old boiler? ### My boiler is making a strange noise — is it dangerous? ### Do you guarantee your boiler repairs?
