FAQs
Do you offer 24/7 emergency repairs for leaking or burst hot-water cylinders in Kingston?
Yes. Our emergency plumbing team is on call 24 hours a day, 7 days a week, including weekends and bank holidays. Once you call, we aim to be at any Kingston postcode within 60 minutes. Our vans carry common valves, immersion elements, and pipe fittings so we can isolate the leak, drain the cylinder if necessary, and carry out a temporary or permanent repair on the first visit whenever possible.
What signs indicate that my hot-water cylinder needs urgent attention?
Contact us immediately if you notice any of the following: • Water pooling around the base of the cylinder or loft tank • Hissing or boiling sounds coming from the cylinder • No hot water and the immersion heater keeps tripping • Water temperature fluctuating rapidly or scalding hot water from taps • Stains, rust, or bulging on the cylinder body • A strong metallic or sulphur smell in hot water These symptoms can point to a failed thermostat, ruptured internal coil, or dangerous pressure build-up that may lead to a burst cylinder.
Can you repair both vented and unvented (Megaflo-type) cylinders during an emergency call-out?
Absolutely. Our engineers are G3-qualified and authorised to work on unvented cylinders as well as traditional vented copper or stainless-steel units. We carry pressure-relief valves, tundish fittings, and expansion vessels for unvented systems and can safely discharge pressure, replace failed components, or, if required, cap off the unit until a full replacement can be arranged.
Will you need to drain my entire heating system to fix a cylinder leak?
Not always. Many leaks occur at fittings or immersion bosses and can be isolated without draining the primary heating circuit. If draining is unavoidable, we use a fast-acting pump to remove water quickly and minimise disruption. For combi-fed cylinders, we can often freeze the supply pipe, replace the faulty part, and thaw the pipe, avoiding full drainage altogether.
How much does an emergency hot-water cylinder repair cost in Kingston?
Our transparent pricing is as follows: • Call-out/diagnostic fee (covers first hour on site): £89 + VAT (weekday), £119 + VAT (evenings/weekends), £149 + VAT (bank holidays/overnight). • Labour after the first hour: £39 + VAT per 30 minutes. • Parts: Charged at trade list price with no hidden mark-up. We provide a full quote before installation. If your cylinder is beyond economical repair, we will give you a fixed quotation for replacement and deduct the emergency labour charge if you proceed within 14 days.
Do you guarantee your emergency repair work and supplied parts?
Yes. All workmanship on emergency repairs is guaranteed for 12 months, and manufacturer warranties apply to any parts we fit (usually 1–5 years depending on the component). If the same fault reoccurs within the guarantee period, we will revisit, diagnose, and rectify the issue free of charge. We are fully insured and Gas Safe & CIPHE registered for your peace of mind.
