Is It Time To Replace Your Boiler?

For many homeowners, boiler replacement isn’t something that’s planned years in advance. More often, it becomes necessary when heating performance begins to decline or repair costs start becoming increasingly frequent.

Many customers in Mumbles contact us when their existing boiler is no longer operating as efficiently as it once did or when they’re looking to improve the overall performance of their heating system.

Common signs it may be time to replace your boiler include:

  • Frequent Breakdowns – Ongoing repair costs and recurring faults
  • Rising Energy Bills – Older boilers are often far less efficient
  • Inconsistent Heating – Uneven temperatures or unreliable hot water
  • Obsolete Parts – Difficulty sourcing replacement components
  • Ageing Systems – Older heating systems nearing the end of their lifespan
Replacing an older boiler can improve efficiency, reduce running costs and provide greater peace of mind.
“Recently had a new combi boiler fitted. Ian was great, explained everything before starting the job. Since installation I can’t believe how quiet the new boiler is.”

We’ll assess your property, heating requirements and existing system before recommending the most suitable gas or oil boiler for your home.

2. System Preparation

Where required, we’ll prepare the system for installation, including pipework alterations, boiler relocations and optional power flushing.

Your existing boiler will be safely removed and your new boiler installed in accordance with current regulations and manufacturer requirements.

Gas Safe & OFTEC Registered

When investing in a new boiler, it’s important to know that the installation will be carried out safely and in accordance with current regulations.

Gas boiler installations must be completed by a Gas Safe registered engineer, while oil boiler installations require OFTEC registration. Swansea Gas Services holds both qualifications, allowing us to provide professional installations across Mumbles and the surrounding area.

Every installation is completed with attention to detail, thorough testing and correct commissioning before handover.
