Who we are

SwiftHeat UK Group Ltd is an award-winning, family-run Welsh company based in Pontypridd, just outside Cardiff. Cardiff and South Wales are at the heart of our business, and we proudly serve homes across Wales. We also deliver boiler installations and whole-home energy solutions across the UK.
Our team brings together more than 20 years’ combined industry experience. Appropriately registered Gas Safe and OFTEC specialists, skilled installers and a dedicated commercial team allow us to take on work ranging from routine boiler care to complex heating installations and multi-property planning.
Our capabilities span gas, oil, LPG and air source heat pump technologies, supporting both domestic and commercial customers across a broad spectrum of heating, plumbing and engineering services. From boiler installation, servicing, repairs and diagnostics to central heating systems, controls, radiators, plumbing and lower-carbon heating solutions, our approach is to understand the complete system and recommend the right solution for the property.
What connects those services is a simple principle: Assess First. Recommend Second. We take time to understand the property, the existing system and the customer’s priorities before proposing work. That leads to clearer choices, better value and fewer decisions made under pressure.
Our promise—The Heart of Your Home, in Expert Hands.—reflects how we see the work. Heating and hot water affect comfort, health, daily routines and household budgets. Technical quality matters, but so do communication, respect for the property and support after the installation.
We use the system history, technical checks and property context to build recommendations that can be explained.
Clear appointments, honest expectations and careful workmanship are part of the service—not optional extras.
We help customers coordinate maintenance, efficiency measures and future low-carbon upgrades sensibly.
SwiftHeat UK leadership
At SwiftHeat UK, growth is about more than expanding the business. It is about building a Welsh heating and engineering company around strong technical standards, energy efficiency, responsible decision-making and exceptional customer care.
That philosophy is reflected in the complementary experience of Managing Director Tristan Jones and Principal Engineer & Co-founder Kieran Heycock.
Read Who’s Behind SwiftHeat UK? for the story behind our approach.


Managing Director
Managing Director Tristan Jones brings more than 16 years of engineering experience across some of the UK’s most technically demanding industries, including oil and gas, petrochemical, chemical, nuclear and steel manufacturing.
His background was developed in high-hazard engineering environments where safety, technical discipline and careful decision-making are fundamental, including environments involving potentially explosive atmospheres, gases, vapours, mists and combustible dusts.
That experience has helped shape his approach to SwiftHeat UK — combining strong technical and compliance standards with careful planning, accountability and a determination to put the customer at the centre of the business.
For me, the customer journey has to be at the heart of everything we do at SwiftHeat UK.
Tristan Jones — Managing Director
We want customers to feel that their home and heating system have been properly assessed, that they understand our recommendations and, importantly, why we are making them.
That’s one of the reasons we’ve developed our Boiler Management Condition Report approach. Whether we’re servicing a boiler, carrying out a heating survey, considering an air source heat pump or designing a new heating installation, we look beyond the individual appliance and consider the property and heating system as a whole.
Assess First. Recommend Second.
That principle is fundamental to the way we want to operate. Every property and every customer is different, and we believe good advice starts with understanding both.
As we scale the business, my focus has always been clear: never compromise on the things that matter — quality, performance, professionalism, technical standards, compliance and, above all, customer care.
Energy efficiency is another major priority. We look beyond the boiler itself and consider the wider system — from appropriate pipework insulation, TRVs and system balancing to zoning and smart controls, including technologies such as OpenTherm, intelligent scheduling and geofencing where appropriate.
We want to help customers improve the energy performance of their homes, including where heating improvements may contribute towards their EPC, while identifying practical opportunities to reduce unnecessary energy use and, where possible, heating costs. Importantly, improving efficiency does not always mean replacing everything — sometimes the right improvements to an existing system can make a meaningful difference.
Customer care also means recognising that everybody’s circumstances are different. We place particular importance on supporting vulnerable customers and households that may require additional assistance, whether that means adapting how we communicate, taking additional time or providing further support where appropriate.
SwiftHeat UK is also a Disability Confident Committed employer. We believe everybody should have an equal opportunity to develop, contribute and thrive. Disability and vulnerability are distinct, and being disabled does not automatically make somebody vulnerable, although there can be circumstances where additional support or reasonable adjustments are appropriate.
Our approach is simple: listen to the individual, understand what they need and treat people with dignity, respect and fairness.
I’m incredibly proud that we’re building a Welsh business providing a comprehensive solution across heating, plumbing, gas engineering, oil and LPG heating systems, and air source heat pumps.
Ultimately, a home’s heating system provides the warmth and hot water families depend upon every day.
It really is the heart of the home, and we believe it deserves to be treated that way.

Principal Engineer & Co-founder · Technical Authority
Kieran Heycock is the technical authority for SwiftHeat UK Group Ltd, including the installations documented in our Our Work evidence showcase. His role connects technical direction, whole-system assessment and the engineering standards behind our heating services.
Principal Engineer and Co-founder Kieran Heycock brings extensive hands-on technical expertise across domestic and commercial gas engineering, plumbing and heating.
His experience encompasses the assessment, diagnosis, installation, servicing and maintenance of heating and gas systems, giving him an understanding not only of individual appliances but of how the complete system needs to work together.
As Principal Engineer, Kieran plays an important role in maintaining SwiftHeat UK’s engineering standards as the company grows.
For me, good engineering starts with properly understanding the property, the system and what the customer actually needs.
Kieran Heycock — Principal Engineer & Co-founder
My background in domestic and commercial gas engineering, plumbing and heating has taught me the importance of looking at the complete system. Whether we’re diagnosing a fault, servicing or replacing a boiler, designing a heating system or assessing whether an air source heat pump is appropriate, the initial assessment matters.
Energy efficiency is part of that whole-system approach too. An efficient appliance alone doesn’t necessarily mean the complete heating system is operating as effectively as it could.
We consider the practical engineering details — controls, TRVs, pipework insulation, zoning, system balancing, system temperatures, water quality and appropriate smart or modulating controls. The objective is to identify where genuine improvements can be made rather than automatically assuming everything needs replacing.
As SwiftHeat UK grows, maintaining those technical standards is incredibly important. We want our engineers to take pride in their workmanship, communicate properly with customers and remember that we are working in somebody’s home or business.
We want to get the engineering right, do the work properly and leave the customer with a system we’re proud to put the SwiftHeat UK name to.

Understand the source
Our Heating Advice guides are published by SwiftHeat UK Group Ltd. The fault and pressure guides link to the manufacturer information used, identify the relevant models and record their publication dates. Use the user instructions for your exact appliance; a similar model name or fault code does not make every procedure interchangeable.
Online guidance helps you describe symptoms and understand the next step. An engineer's assessment establishes the cause and appropriate work for your property. Gas Safe number 978273 identifies our registered business; it is not presented as an individual author's engineer number.
Our leadership profiles explain Tristan Jones's role as Managing Director and Kieran Heycock's role as Principal Engineer and Technical Authority. If something in a guide is unclear or appears out of date, send us the page link and your feedback.

What we do differently
A boiler or heat pump does not work alone. Pipework, circulation, radiators, underfloor heating, water quality, balancing, controls, zoning, hot-water demand and the building fabric all influence the outcome. Our holistic approach considers those connections rather than treating the heat source as an isolated box.
That can mean identifying a poorly balanced system before recommending a larger boiler, checking radiator output before lowering temperatures, or improving controls before asking the customer to fund major work. For a heat-pump transition, it means understanding heat loss, emitters, hot water, space, electrics and how the household actually lives.
Not every home needs every improvement. Our role is to distinguish essential work from useful opportunities and longer-term choices. Customers receive plain-English reasoning so they can decide with confidence.
A SwiftHeat UK innovation

Assess First.
Recommend Second.
SwiftHeat UK Group Ltd includes a complimentary Boiler Management Condition Report with every boiler service and boiler installation we carry out, at no extra charge.
Heating decisions are often reactive. A breakdown happens, information is incomplete and the customer must choose quickly between another repair and a replacement. Our Boiler Management Condition Report creates a more structured alternative.
The assessment brings together accessible evidence about the boiler and wider heating system: condition, performance, recurring faults, controls, circulation, heat delivery, water-quality indicators and maintenance history. Findings are organised into immediate concerns, planned actions and future improvement opportunities.
A report does not automatically recommend a new boiler and does not replace statutory safety checks or a building survey. Its purpose is to help homeowners, landlords and property managers understand risk, spend in the right order and prepare for upgrades. Explore Boiler Management Condition Reports →
