Gas, LPG & Oil Boiler Engineers

A reliable boiler is essential for keeping your property warm, safe and running efficiently. Heatworks provides professional boiler installation, repairs and servicing across South Wales, carried out by fully qualified Gas Safe and OFTEC registered engineers.

Whether you are replacing an old boiler, dealing with a breakdown, arranging a service or planning a heating upgrade, we give clear advice and complete the work properly from start to finish.

Boiler Installation & Replacement

If your boiler is old, inefficient, unreliable or no longer cost-effective to repair, Heatworks can help you choose and install the right replacement system for your property.

We provide boiler installation and replacement across Bridgend, Port Talbot, Neath, Swansea, and Cardiff, working with homeowners, landlords, developers and light commercial properties.

We install and work with modern gas, LPG and oil boiler systems designed for efficiency, performance and long-term reliability. Every installation is specified around the property, heating demand, hot water requirements and existing system design – not simply fitted as a like-for-like replacement.

Boiler Repairs & Fault Finding

A boiler fault can leave your property without heating or hot water, so accurate diagnosis matters. Our engineers inspect the system, identify the likely cause and explain the repair options clearly before carrying out work.

We help with common boiler problems including:

  • No heating or hot water
  • Low pressure or pressure loss
  • Boiler leaks
  • Ignition and flame failure faults
  • Noisy boilers or pipework
  • Fault codes and intermittent breakdowns
  • Heating controls and thermostat issues

Where a repair is practical and cost-effective, we will explain what is needed. If the boiler is unsafe, obsolete or uneconomical to repair, we will give honest replacement advice.

For wider heating problems, we can also support fault finding through our central heating services and plumbing services where the issue is connected to pipework, controls, radiators, pressure loss or system design.

Boiler Servicing & Maintenance

Regular boiler servicing helps keep your heating system safe, efficient and reliable. An annual service can identify early signs of wear, reduce breakdown risk and help ensure the boiler is operating as it should.

Our boiler servicing may include:

  • Visual inspection of the boiler and flue
  • Gas safety and combustion checks where applicable
  • Oil appliance checks where applicable
  • Inspection and cleaning of key components
  • Checks to controls and safety devices
  • Performance and efficiency checks
  • Advice on system condition and future maintenance

We provide boiler servicing for homeowners, landlords, property managers and light commercial customers, including Landlord Gas Safety Certificates where required.

Boiler Installation as Part of a Heating Upgrade

A boiler replacement is often the right time to review the wider heating system. Poor radiator sizing, old pipework, inefficient controls or system sludge can all affect boiler performance.

Where needed, we can advise on:

  • Radiator upgrades
  • Heating controls and zoning
  • Pipework alterations
  • System balancing
  • Powerflushing
  • Compatibility with future heating upgrades

This helps ensure the new boiler works efficiently with the rest of the property, rather than masking existing system problems.

Domestic, Landlord & Commercial Boiler Work

We carry out boiler work for:

  • Homeowners
  • Landlords and letting agents
  • HMOs and multi-unit properties
  • Renovation and development projects
  • Small commercial premises

Whether it is a single boiler replacement, a landlord service visit or part of a wider heating upgrade, we focus on safe, compliant and reliable results.
