5 out of 5 stars
Last week I had a Renzy engineer come out to fix my boiler after being let down by 2 other local companies. The engineer arrived on time and managed to fix my boiler the same day. Really impressed and will definitely be recommending.
If it's over 10 years old or keeps breaking down, it may be time for a new one. New boilers are fitted at a fixed price, from £1,995.
Boilers are essential for your home's heating and hot water. Our engineers have extensive experience with all major boiler brands and can quickly resolve issues to restore your comfort.
We repair boilers from all manufacturers including Worcester, Vaillant, Baxi, Ideal, Glow-worm, and many others.
We're experienced in resolving boiler issues like diverter valve problems, plate heat exchanger faults, and flow issues.
We carry parts for common boiler faults, allowing us to complete many repairs on the first visit to minimize disruption.
Common boiler issues include diverter valve faults (causing heat but no hot water), plate heat exchanger problems (often due to limescale), pressure loss, pump failures, and ignition problems. Our engineers can diagnose and fix these issues efficiently.
This is typically caused by a faulty diverter valve, which should switch between heating and hot water modes. It's one of the most common boiler problems and one our engineers are very experienced in resolving.
We aim to repair your boiler on the first visit whenever possible. For standard appointments, we can typically attend within 24-48 hours. If specific parts need to be ordered, we'll provide a clear timeframe for completing the repair.
This depends on the boiler's age, condition, and the nature of the fault. For boilers under 10 years old, repairs are usually worthwhile. For older models with significant issues, we'll provide honest advice about whether repairing or replacing your boiler offers better long-term value.
Boilers can lose pressure due to leaks in the system, issues with the expansion vessel, or problems with the pressure relief valve. Our engineers will identify the specific cause and provide a lasting solution rather than just topping up the pressure. If you're unsure what's causing it, try our low pressure diagnostic tool.
