    Service Overview

    Comprehensive Plumbing for Every Situation

    Our plumbing services cover the full range of domestic plumbing requirements — from new installations as part of renovation projects, through to maintenance, repairs, and emergency call-outs. We install and maintain hot and cold water systems, waste and drainage, central heating, underfloor heating, and gas appliances.

    Plumbing work is needed when renovating kitchens and bathrooms, replacing boilers and heating systems, resolving leaks and drainage problems, or upgrading outdated pipework. It is also required as part of new-build and extension projects where water, waste, and heating services need to be installed from scratch.

    Using a certified plumber protects your property and your family. Gas work by unregistered operatives is illegal and dangerous. Water supply connections that don't meet regulations can contaminate drinking water. Drainage installed without proper fall causes blockages and backflow. Every aspect of our plumbing work meets or exceeds current regulations.

    Comprehensive Plumbing for Every Situation

    Why It Matters

    Why Plumbing Problems Escalate Quickly

    Water is the most destructive force in a domestic property. A pinhole leak in a concealed pipe can release thousands of litres of water before detection, saturating floor structures, walls, and ceilings. The remediation cost for water damage consistently exceeds the repair cost of the leak itself — often by a factor of ten.

    Drainage problems compound over time. A partial blockage causes slow drainage, which leads to standing water in pipes, which accelerates the buildup of fats, soap, and debris, which worsens the blockage. By the time drainage completely fails, the problem often requires excavation and pipe replacement rather than a simple clearance.

    Boiler and heating failures are more than an inconvenience — they can be a safety risk. A poorly maintained boiler can produce carbon monoxide, an odourless gas that causes illness and death. Annual servicing by Gas Safe registered engineers is not optional; it is essential for the safety of your household. We provide both one-off and ongoing maintenance services.

    In-Depth Detail

    Our Plumbing Capabilities in Detail

    Bathroom & Kitchen Plumbing

    Complete plumbing for bathroom and kitchen installations including hot and cold supply in copper or PEX, waste connections in solvent weld or push-fit, and all fixtures from taps and mixers to shower valves and waste disposal units. We work within renovation schedules and coordinate closely with other trades to ensure efficient project delivery.

    Boiler Installation & Replacement

    We supply and install combi, system, and regular boilers from leading manufacturers including Worcester Bosch, Vaillant, and Ideal. All installations include power flush of the existing system, magnetic filter fitting, system inhibitor dosing, and commissioning. Gas Safe certificates are issued for every installation.

    Central Heating & Radiators

    Full central heating system design and installation, radiator upgrades and repositioning, thermostatic radiator valve fitting, and power flushing. We calculate heat loss room by room to specify correctly sized radiators. Smart thermostat installation (Nest, Hive, etc.) is available to maximise efficiency and control.

    Underfloor Heating Systems

    We install both wet (hydronic) and electric underfloor heating systems. Wet systems are connected to your existing boiler and are ideal for new-build or extension projects. Electric mat systems are suited to individual rooms, particularly bathrooms and kitchens. Both types work effectively beneath tile, stone, and engineered timber flooring.

    Leak Detection & Repair

    We locate and repair leaks in supply pipes, waste pipes, heating systems, and external drainage. Our approach minimises disruption — we use acoustic detection and thermal imaging where possible to pinpoint leaks without unnecessary excavation or wall opening. Once located, repairs are carried out using appropriate methods and materials.

    Drainage & Waste Systems

    Soil pipe installation and modification, waste pipe routing, drainage connections, and external drainage including gullies and inspection chambers. We clear blocked drains using rod and jet methods. For persistent or structural drainage problems, we undertake CCTV survey and excavation for pipe repair or replacement.

    Our Proven Process

    How We Deliver Results

    01

    Assessment & Diagnosis

    We assess the plumbing requirement — whether it is a new installation, repair, or system upgrade. For problems, we diagnose the root cause before recommending a solution. For new work, we survey the property and design the optimal pipe routing.

    02

    Quotation & Specification

    A clear, itemised quotation detailing all materials, labour, and certification costs. For boiler installations, we specify the correct boiler type and output for your property's hot water and heating demands.

    03

    Installation / Repair

    Work is carried out efficiently with minimal disruption. Water supply is maintained wherever possible during installation work. All joints and connections are tested under pressure before being concealed or commissioned.

    04

    Pressure Testing & Commissioning

    New installations are pressure-tested at 1.5x operating pressure to verify the integrity of every joint. Heating systems are balanced, boilers commissioned, and all controls set up and demonstrated to you.

    05

    Certification & Handover

    Gas Safe certificates, unvented cylinder notification, and Building Regulations compliance documentation are issued as applicable. You receive a summary of all work completed and aftercare instructions.
