State-of-the-Art Boiler Installations & Replacements
An outdated boiler can waste over 30% of your energy and leave your household vulnerable to costly mid-winter breakdowns. At RDM Plumbing & Heating, we specialise in precision-engineered condensing boiler replacements that cut fuel bills and ensure reliable warmth.
Every installation includes magnetic system filtration, full system chemical cleanse, and smart digital thermostats for ultimate energy control.
Emergency Plumbing When You Need It Most
Water leaks and burst pipes don't wait for business hours. When plumbing disasters strike, our dedicated rapid-dispatch vans are fully equipped to diagnose, isolate, and repair plumbing emergencies within 30 to 60 minutes.
We believe in honest craftsmanship with zero hidden callout charges. You only pay for genuine repair time and materials agreed before work begins.
Bespoke Bathroom Design & Precision Fitting
Transform your outdated bathroom into a calming, luxurious retreat. RDM manages the complete renovation from initial design concepts and spatial planning to premium tiling, plumbing, electrical installations, and final silicone finishing.
We work with leading British and European sanitaryware brands to create functional, elegant wetrooms, master en-suites, and family bathrooms built to last a lifetime.
Advanced Thermal Imaging & Power Flushing
Are your radiators cold at the bottom? Is your boiler whistling or losing pressure? Over time, heating systems accumulate black magnetic sludge that severely restricts heat circulation and forces your boiler to overwork.
Using digital thermal imaging cameras and high-velocity power flushing machines, we identify cold spots and flush out debris without disrupting your home.

Got Questions? We Have Answers
Everything you need to know about our plumbing services, emergency response, boiler warranties, and pricing.
How quickly can you respond to an emergency plumbing or boiler callout?
For urgent plumbing emergencies (such as burst pipes, active water leaks, overflowing toilets, or complete heating failure in winter), our average local arrival time is between 30 and 60 minutes. We have dedicated mobile vans on shift 24 hours a day, 7 days a week.
Do you charge a call-out fee?
No, we operate a transparent no-call-out-fee policy during standard working hours. We inspect the problem and provide a clear, upfront quote before starting any work. You only pay for the agreed repair or installation.
Are all of your heating engineers Gas Safe registered?
Yes, absolutely. Every engineer on our team is fully certified and listed on the official Gas Safe Register (Registration #839201). Our technicians carry official photo ID badges showing their qualifications, which you are welcome to verify upon arrival.
What warranty do you offer on new boiler installations?
Because RDM is an Accredited Installer for top manufacturers like Worcester Bosch, Vaillant, and Ideal, we can provide exclusive extended manufacturer warranties ranging from 10 to 12 years covering both parts and labour. We also provide our own 12-month workmanship guarantee on all pipework.
How do I know if my heating system needs a power flush?
Common symptoms of sludge buildup include radiators that remain cold at the bottom while hot at the top, noisy kettle-like sounds coming from your boiler, slow heating warm-up times, or dark rusty water when bleeding radiators. A power flush removes this debris and restores optimal heat circulation.
Do you provide Landlord Gas Safety Certificates (CP12)?
Yes. We carry out thorough landlord gas safety inspections across rental properties and HMOs. Once complete, we email official digital CP12 PDF certificates immediately to landlords and estate agents, complete with automatic annual renewal reminders.
