Boiler Installations
We install high-efficiency gas, oil, and LPG boilers with smart controls for remote temperature management. Our Gas Safe engineers ensure safe installation and compliance with current regulations. Modern boilers reduce energy consumption while maintaining optimal heating performance for Cornwall homes.
Underfloor Heating
Our underfloor heating systems eliminate radiators while providing even heat distribution. Hidden pipework improves interior aesthetics and space utilisation. This energy-efficient solution integrates with existing heating systems for enhanced comfort in Cornish properties.
Plumbing Services
We handle bathroom and kitchen plumbing installations alongside emergency repairs. Our services include pipe maintenance, fixture installations, and system upgrades. Available for both scheduled projects and urgent plumbing emergencies across Mid-Cornwall.
Unvented Hot Water Systems
We install high-pressure unvented hot water systems with lifetime guarantees. These systems eliminate cold water tanks while providing mains-pressure hot water. Sealed systems prevent contamination and reduce noise from water refill operations.
Central Heating Servicing
Regular boiler servicing extends system lifespan and maintains efficiency. Our annual safety checks meet legal requirements for landlords. Serviced systems receive priority emergency support between scheduled maintenance visits.

Terrific service from Steve.
Contacted him in the morning and said he would call later that day
Arrived as promised, diagnosed fault within minutes and fixed/tested within the hour. Very reasonable charge and I would not hesitate in recommending this company. Thanks again Steve

We have been using Steve now since we moved into our new house some 4 years ago, Steve has done an amazing job sorting out our ageing boiler, servicing it and getting it back into ship shape condition. Whenever there is an issue Steve is quickly at hand and it's never to much trouble for him to give advise or to come around and sort any issues that may occur - I cannot rate Steve - St Austell Plumbing & Heating highly enough.

Called Steve initially to service a boiler and mentioned a few other issues with the heating and hot water that needed attention. Some of these problems had gone on for some time, despite various visits by other companies. Once Steve got to work all problems were resolved really quickly and professionally and would recommend him to anyone. Great service.
