Credentials & Accreditations
Hydronic underfloor heating — also known as wet or water-based UFH — provides energy-efficient, radiant warmth by circulating warm water through pipes installed beneath your flooring. The result is even heat distribution throughout the room, improved comfort underfoot, and complete design flexibility with no radiators on your walls.
Suitable for most floor types — including tiles, stone, and wood — and fully compatible with modern, eco-friendly heat pumps for the lowest possible running costs. It's the modern heating standard, and it's what Meridian Plumbing specialises in across London.
Hydronic UFH delivers warmer rooms, the lowest running costs of any heating system, and a better-looking home — all at once.
UFH runs at lower flow temperatures than radiators, cutting heating bills while delivering a more even warmth across the room.
No radiators. No exposed pipework. Just clean walls and complete design freedom — perfect for modern, minimalist interiors.
Heat rises from the entire floor surface, eliminating cold spots and hot zones near radiators. Warm feet, comfortable rooms.
Wet UFH pairs perfectly with air source and ground source heat pumps, future-proofing your home for the next decade.
No clanking radiators, no humming pumps, no ticking pipes as the system warms. Heating that disappears into the background.
A genuine selling point in modern London homes. Buyers actively look for underfloor heating in higher-end listings.
A simple, elegant heating method that's been the European standard for decades — now the smart choice for modern UK homes.
Warm water is generated by your existing boiler or — for maximum efficiency — a modern heat pump. Hydronic UFH runs at low flow temperatures (35-55°C), exactly what heat pumps deliver best.
Water is distributed through a premium manifold — we fit trusted brands including Ambiente — out to each room's pipe circuit. Every room becomes its own heating zone with independent thermostat control: heat only what you use.
Continuous PEX or PE-RT pipework is laid in serpentine loops beneath the floor — under screed for new builds, or in low-profile retrofit panels for existing homes (just 15-20mm thick).
The floor itself becomes the heat emitter, delivering even radiant warmth from beneath your feet — no cold spots, no hot zones, no radiators. Pure, comfortable, efficient heating.
Electric UFH costs about 3-4× more to run than hydronic over its lifetime — fine for a small bathroom, but not for whole-house heating. Hydronic delivers the lowest running costs of any heating system, especially when paired with a heat pump. That's why every install we do is hydronic — it's the right long-term investment.
From a single warm bathroom floor to a complete whole-house heat pump and UFH project — Meridian Plumbing handles the full range of hydronic systems.

Hydronic (wet) underfloor heating installation in London typically costs between £85 and £120 per square metre installed. The exact price depends on the floor area, retrofit complexity, insulation requirements, number of manifold zones, and whether it ties into a new boiler, existing boiler, or heat pump. Meridian Plumbing offers competitive London pricing and provides a free, no-obligation quote within 24 hours.
Hydronic UFH delivers the lowest running costs of any modern heating system because it runs at low flow temperatures (35-55°C). It pairs perfectly with heat pumps — the most efficient heat source available — making hydronic the gold standard for whole-house heating. Electric UFH is roughly 3-4× more expensive to run long-term, so we recommend it only for very small areas like a single bathroom (and we don't install electric ourselves — hydronic is our speciality). Compared to radiators, hydronic UFH delivers more even comfort, better efficiency, and frees up every wall in your home.
Yes. Retrofit hydronic underfloor heating is one of our specialities. We install low-profile wet UFH systems that add as little as 15-20mm to floor height, ideal for renovations and existing properties. Retrofits are typically completed in 1-3 weeks depending on scope. We assess your floor build-up, insulation and existing heat source during the free site survey before quoting.
Yes. Underfloor heating is the ideal heating distribution system for both air source and ground source heat pumps. Heat pumps operate most efficiently at low flow temperatures (35-45°C), which is exactly what wet UFH systems are designed to run on. This pairing delivers the lowest possible running costs and maximises the efficiency of your heat pump. We design and install heat pump compatible UFH systems across London.
A single-room hydronic UFH install typically takes 3-5 days. A whole-house wet UFH retrofit in a 3-bed property typically takes 1-2 weeks including manifold installation, pipe laying, screed pour (where applicable), and commissioning. New build installs are usually quicker because the floor build-up is designed around the UFH from day one.
In most cases, yes. UFH can be designed as the sole heat source for a room or property, removing radiators entirely and freeing up wall space. In some retrofit or partial install scenarios it can be used alongside existing radiators, with each room individually zoned. We assess and advise on the best approach during the site survey.
Every installation includes: free site survey, written quote within 24 hours, system design tailored to your room layout and heat loss, all materials supplied, professional installation by Gas Safe registered engineers, pressure testing, commissioning, thermostat and zone control setup, full walkthrough on day of handover, and a workmanship guarantee. We coordinate with your flooring contractor and screeders where required.
