Our Services in Cardiff

Cardiff's diverse property landscape, from converted Victorian houses in Roath to new-build apartments in the Bay, calls for a plumber who can adapt. We bring the right skills, tools, and experience to every job, whether residential or commercial.

Many of Cardiff's older neighbourhoods, particularly Cathays, Roath, and Splott, feature Victorian terraced houses with original plumbing systems that need careful handling. Our engineers understand how to work with period properties: replacing old lead pipework, upgrading heating systems, and fitting modern bathrooms without damaging original features.

New Boiler Installation in Cardiff

Cardiff's housing is a real mix, from tall Victorian terraces in Cathays and Roath, to leafy Edwardian homes in Pontcanna and Llandaff, to modern apartments in Cardiff Bay and the city centre. Each property type calls for a different approach to boiler installation, and that is exactly where our experience pays off.

We fit all the major boiler brands at homes across Cardiff, including Worcester Bosch Greenstar, Vaillant ecoTEC, and Baxi ranges. For a typical two- or three-bedroom Cardiff terrace, an A-rated combi boiler is usually the most efficient choice: it frees up space by removing the hot water cylinder and cold tank, and delivers hot water on demand. For larger family homes in Llandaff or Cyncoed with two or more bathrooms in regular use, a system boiler running off a sealed cylinder will keep showers strong even when several taps are open at once.

A specialism of ours in Cardiff is converting older properties away from open-vented heat-only systems and back boilers. Many Victorian and Edwardian homes still rely on tank-fed setups that are inefficient and prone to corrosion. Our boiler installations in Cardiff include full system flushing, modern load-compensating controls, and a magnetic filter as standard, all of which protect the new appliance and improve efficiency over the long term. Every install is carried out by Gas Safe registered, City & Guilds qualified engineers, with full Building Regulations notification handled on your behalf.

We also work with a number of Cardiff landlords and letting agents on planned boiler replacement programmes across rental portfolios. If you would like a quote for a single new boiler or for multiple properties, see our heating services page for more on the systems we install, or get in touch for a free site survey.

Choosing the Right Boiler for Your Cardiff Home

Property type, household size, and how you actually use hot water all influence the right boiler choice. Use the rough guide below as a starting point, then book a free survey and we will give you a definitive recommendation for your Cardiff property.

Combi Boiler

Cathays / Roath / Splott terraces, city flats

Compact, efficient, and self-contained. Heats hot water on demand with no need for a cylinder or loft tank. Ideal for smaller and mid-sized Cardiff homes with one bathroom and modest hot water demand.

System Boiler

Llandaff / Cyncoed / Pontcanna family homes

Pairs with a sealed hot water cylinder. Better for larger Cardiff homes with two or more bathrooms running simultaneously, or households with high hot water demand at peak times.

Heat-Only / Regular

Period properties retaining tank-fed systems

Sometimes the right call for older Cardiff properties where a full conversion would be disruptive. Used with a hot water cylinder and feed-and-expansion tank in the loft.

Modern A-rated boilers fitted by RH Plumbing in Cardiff meet the current ErP efficiency requirements and include programmable controls and a system filter as standard. For Welsh homeowners on qualifying benefits or a low income, schemes such as Nest Wales and ECO4 can sometimes contribute towards a replacement boiler. We are happy to point you towards the official scheme guidance if you think you may be eligible.
