A broken boiler is miserable — especially in winter. At DRMB, our Gas Safe engineers are equipped to diagnose and fix your boiler quickly, often on the first visit.
We carry a comprehensive stock of parts in our vans for the most common boiler brands. Whether your boiler is displaying a fault code, making strange noises, leaking, or simply won't fire up — we've seen it and fixed it hundreds of times.
Common Boiler Problems We Fix
Our Diagnostic Process
When we arrive, we don't guess — we diagnose. Using specialist boiler analysis tools, we perform a full combustion check and system inspection to identify the exact cause of your fault. We'll explain what we've found in plain English and give you a clear, written quote before carrying out any repair.
Transparent pricing, always. No surprise charges on the invoice. If the repair isn't cost-effective compared to a new boiler, we'll tell you honestly — and help you find the best replacement option through our new boiler installation service.
Need your boiler looked at urgently outside of normal hours? Our 24/7 emergency plumber service covers boiler breakdowns day and night across SE London. We also recommend an annual boiler service to catch issues before they become costly repairs.
