Services
Boiler Installation
We install modern boilers from leading manufacturers like Viessmann and Ideal across South Wales. Our Gas Safe Registered engineers ensure safe, efficient installations with options for LPG and oil boilers. Customers benefit from extended warranties on Ideal Max installations and same-day waste removal. The process includes expert guidance on selecting the right boiler size and type for your property's specific needs.
Boiler Servicing
Our comprehensive boiler services maintain system efficiency and warranty validity. Engineers perform safety checks, flue inspections, pressure adjustments, and component cleaning. Annual servicing reduces breakdown risks and energy bills while meeting legal requirements for landlords. We provide detailed explanations of maintenance needs and offer emergency support for post-service issues.
Central Heating Installation
We design and install complete central heating systems with modern controls and energy-efficient components. Services include radiator upgrades, underfloor heating integration, and smart thermostat installations. Our engineers optimise system performance to reduce energy consumption while improving temperature control. We specialise in replacing outdated systems with modern, energy-saving alternatives that increase property comfort levels.
Powerflushing
Our powerflushing service removes sludge and limescale buildup from central heating systems. Using specialist chemicals and high-velocity water flow, we restore system efficiency and extend boiler lifespan. The process includes descaling, corrosion inhibition, and blockage removal. This service improves radiator performance, reduces energy bills, and prevents future system failures while maintaining manufacturer warranties.
Smart Thermostat Installation
We install advanced smart thermostats including Nest and Hive models that enable remote temperature control via smartphone apps. These systems learn user preferences and optimise heating schedules to reduce energy consumption. Our engineers ensure compatibility with existing boilers and provide full operation training. Smart controls offer precise temperature management and energy usage monitoring for improved household efficiency.

Boiler packed in on Friday and suggested a very cold weekend ahead. Great response from James who arrived within a couple of hours of contact. Super friendly, professional and got us back up and running. Great follow up with comms to arrange repair and service and also answered questions about options of upgrading system without any pressure or upselling. Really impressed and 100% recommend.

What can I say? Ive been with James since I purchased my property 3 years ago. James is very punctual, attention to detail is second to none. Everything you could want from an engineer.
Honestly I look forward to seeing James once every year. We have great conversations, very polite, understanding, you get more than what you pay for with James, as he will go above and beyond to solve any other issues. Always a pleasure James! See you next year!

I think this is the 7th year James has done our boiler service, I wouldn't trust anyone else! He's even happy to work around the chaos of our school run!
