Serving Liverpool, Manchester, Wirral, St Helens, Warrington, and all surrounding areas across Merseyside and Greater Manchester - Your trusted local underfloor heating specialists since 1998

Are you dreaming of walking on wonderfully warm floors in your Liverpool home or Manchester property? Perhaps you're tired of cold bathroom tiles on winter mornings in your Wirral home, or looking to upgrade the heating in your St Helens property? Underfloor heating isn't just a luxury reserved for high-end developments; it's becoming an increasingly popular and practical heating solution for homes across Merseyside and Greater Manchester. With energy costs rising and homeowners seeking more efficient heating solutions, underfloor heating offers a fantastic way to heat homes efficiently, comfortably, and invisibly.
But here's the crucial point: getting underfloor heating right, from initial planning to final commissioning, is absolutely key to its success. This isn't a DIY weekend project or something to entrust to a general builder; it's a specialist job requiring experienced, qualified heating engineers who understand the unique challenges of properties in Liverpool, Manchester, and the wider Northwest region.
In this comprehensive guide, we'll take you through everything you need to know about underfloor heating installation, using real-life examples from recent projects across Merseyside, including Liverpool city centre conversions, Manchester suburban installations, and traditional property renovations throughout the Northwest.
Understanding Underfloor Heating: The Basics for Northwest Homeowners

Before diving into installation details, let's explore why underfloor heating has become so popular across Liverpool, Manchester, and Merseyside. Unlike traditional radiators that heat air (which then rises, creating cold spots), underfloor heating turns your entire floor into a gentle, radiant heat source.
This means:
Even heat distribution throughout your Liverpool apartment or Manchester home
No cold spots - perfect for those draughty Victorian properties common across Merseyside
Lower running temperatures (typically 35-45°C compared to 60-70°C for radiators)
Energy savings of 15-25% - crucial with Northwest England's heating demands
More wall space - no radiators means more room for furniture in compact city properties
Reduced air circulation - less dust movement, better for allergies
Compatible with renewable energy - works brilliantly with heat pumps

Why Expert Planning is Essential for Underfloor Heating Installation in Liverpool & Manchester
Before a single pipe is laid in your Liverpool terrace, Manchester semi-detached, or Merseyside new-build, the most crucial step is having professional heating engineers conduct a thorough system planning and survey. This initial consultation is free with DD Wilson and absolutely essential for project success.
Whether you're renovating a Victorian property in Liverpool's Georgian Quarter, updating a 1930s semi in Manchester's Didsbury, or installing heating in a new-build development in Warrington, proper planning prevents costly mistakes. Think of it as creating the perfect blueprint for your cosy home. Skipping professional planning is like building a house without foundations – it simply won't work out well, and you'll likely face problems ranging from uneven heating to damaged floors or sky-high running costs.

Let's delve into the installation process, breaking down what happens during a professional underfloor heating installation in properties across Liverpool, Manchester, and the surrounding areas. This detailed understanding helps homeowners appreciate the importance of professional installation.
Stage 1: Comprehensive Floor Preparation - Liverpool & Manchester Standards
Proper subfloor preparation is the foundation of successful underfloor heating, especially given the variety of property types across Merseyside and Greater Manchester:
For Solid Concrete Floors (common in newer Liverpool waterfront developments and Manchester city centre apartments):
Surface must be level within 5mm across any 2-metre stretch
Moisture content checked with professional meters (must be below 75% RH)
Any cracks or damage should be repaired with appropriate compounds
Old adhesive residues were removed completely
Primer is applied if required for insulation board adhesion
Damp-proof membrane checked and repaired if necessary
For Suspended Timber Floors (typical in Victorian and Edwardian properties across Liverpool and Manchester):
Comprehensive joist inspection for strength and spacing
Additional noggins fitted between joists if required
Boards were checked for stability and movement
Ventilation is assessed to prevent moisture issues
Acoustic considerations for apartments
Load calculations for additional weight
Special Considerations for Northwest Properties:
Many Liverpool terraces have cellars requiring vapour barriers
Manchester's clay soil areas need movement joints
Coastal properties in Merseyside need extra moisture protection
Conservation area properties may have restrictions
