Whole-Home Plumbing & Heating: How We Upgrade with Care
From Survey To Sign-Off: How We Operate
Renovating your property means thinking beyond fixtures and finishes. Our team takes a joined-up approach to plumbing and heating — carefully planning upgrades that improve your home’s performance from the inside out.
Whether you’re replacing old pipework, modernising your boiler, or redesigning heating zones, we keep every stage clean, safe, and fully coordinated with the rest of your refurbishment.
System Disconnection & Protection
We begin by safely isolating your existing water and heating systems. Key surfaces and finishes are protected before any removal work begins — especially in bathrooms, kitchens, and utility areas.
Pipework Routing & Radiator Planning
New plumbing and heating layouts are tailored to your home’s design and future use. We prepare for efficient water flow, tidy radiator placement, and pipe rerouting and plumbing prep that keeps everything discreet.
Heating System Installation & Power Flush
Our Gas Safe team installs your new boiler, radiators, and thermostats, followed by a full power flush to clean the system. We ensure optimal pressure, flow, and heating response throughout the home.
Final Testing & Commissioning
Before sign-off, we test everything from pressure to thermostat response — making sure your home runs smoothly and efficiently. You’ll get full documentation, settings guidance, and peace of mind.

Not always. If your current plumbing is in good condition and suits your new layout, we may be able to retain or partially upgrade it. We’ll carry out a full assessment and advise on the most cost-effective and futureproof option.
We often recommend zoned radiator systems, combination or system boilers, and underfloor heating in select areas. These provide energy efficiency and modern comfort while still working well with period layouts and insulation levels.
It depends on the size and scope of your home, but typically, a full system upgrade (including pipework, boiler, radiators, and fixtures) takes between 1–3 weeks. We’ll always give you a clear timeline before starting work.

In some cases, yes — particularly for phased upgrades. However, for full-home refurbishments involving system-wide work, it may be more practical to vacate for a short period. We’ll talk you through your options during the planning stage.
