Choosing a new heating system is a major investment, but choosing the right installer is just as important. Even the best boiler or heating equipment won't perform properly if it's installed incorrectly.
At Iveagh Heating, we've seen first-hand the difference that quality workmanship can make. We've also been called out to fix problems caused by poor installations that could have been avoided by asking a few simple questions before hiring a contractor.
If you're looking for a heating engineer in Banbridge or the surrounding areas, here are the questions every homeowner should ask before making their decision.
Are You Fully Qualified and Accredited?
This should always be your first question.
Any engineer working on gas appliances should be Gas Safe registered, while anyone installing or servicing oil-fired heating systems should be OFTEC registered.
These accreditations show that the engineer has been properly trained, assessed, and regularly monitored to ensure they meet strict safety and technical standards.
Choosing an accredited installer gives you confidence that your heating system is being installed safely, legally, and in accordance with current regulations.
Will You Recommend the Best System for My Home?
Be cautious of anyone who recommends a new boiler before they've even looked at your property.
A professional installer should take the time to understand:
The age of your home
Your current heating system
Your home's EPC rating
Levels of insulation
Your heating and hot water requirements
Your budget and future plans
At Iveagh Heating, we believe every home is different. While heat pumps are becoming increasingly popular, they aren't suitable for every property. Older homes with lower energy efficiency may benefit more from an oil or gas boiler unless wider energy improvements are carried out first.
The right installer will recommend what's right for your home, not simply the latest technology.
Will You Assess My Entire Heating System?
One of the biggest mistakes we see homeowners make is focusing solely on replacing the boiler.
A heating system is made up of many components, including:
Heating controls
Programmers
Motorised valves
Hot water cylinders
Oil tanks
Pipework
These parts often reach the end of their lifespan around the same time as the boiler.
A good installer should inspect the entire system and explain whether any other components should be upgraded to improve efficiency, reliability, and long-term performance.
Will You Help Me Improve Energy Efficiency?
Installing a new boiler is only one part of making your home more energy efficient.
One of the most common issues we encounter is poor loft insulation. Many homeowners spend thousands replacing their heating system while large amounts of heat continue to escape through the roof.
A trustworthy installer should be willing to offer honest advice that goes beyond simply selling a boiler.
Sometimes, improving insulation or ventilation can make just as much difference as upgrading your heating system.
Can You Give Me Honest Advice Instead of the Most Expensive Option?
One thing we've always believed at Iveagh Heating is that every recommendation should be based on what's best for the customer, not what's most expensive.
For many homeowners, a like-for-like boiler replacement is the most practical and cost-effective solution because it avoids major alterations to existing pipework.
Equally, there are times when investing in additional upgrades now can save significant money and inconvenience in the future.
An experienced installer should explain your options clearly, outlining both the benefits and costs so you can make an informed decision.
Experience Matters: Looking Beyond the Boiler
One project that stands out involved a customer who was suffering from ongoing respiratory health issues.
Rather than simply replacing the boiler, we looked at the home as a whole and recommended several improvements, including:
Upgrading the loft insulation
Replacing old windows and doors
Installing a modern condensing oil boiler
Removing an open-flue fossil fuel fire
Installing a positive input ventilation system
The result wasn't just a more efficient heating system, it was a warmer, healthier, drier home that significantly improved the customer's day-to-day comfort.
This is why choosing an experienced installer matters. Sometimes the best solution isn't just replacing a boiler, it's understanding how every part of the home works together.
Questions to Ask Before You Hire
Before choosing an HVAC or heating installer, make sure you ask:
Are you Gas Safe and/or OFTEC registered?
Have you installed systems similar to mine before?
Will you assess my whole heating system?
Will you explain all of my options?
Can you provide references or customer reviews?
What warranties or guarantees do you offer?
Will you leave my home clean and tidy after the work is complete?
Do you provide ongoing servicing and maintenance?
A reputable installer will be happy to answer every one of these questions.
