Your Safety Comes First

There are several signs that may indicate it’s time to consider replacing your boiler. If your boiler is over 10–15 years old, it may be less efficient and more prone to breakdowns. Frequent repairs, rising energy bills, or difficulty finding replacement parts can also be indicators.

Other warning signs include unreliable heating or hot water, unusual noises, visible leaks, or a boiler that regularly loses pressure. In some cases, an older boiler may still work but no longer run efficiently, meaning it costs more to operate than a modern replacement.

A professional boiler inspection is the best way to know for sure. At Gills Gas Solutions, we provide honest advice based on safety, efficiency, and cost-effectiveness — and we’ll only recommend a replacement if it’s genuinely the best option for your home.

In many cases, yes — especially if your current boiler is older or inefficient. Modern boilers are designed to be far more energy efficient, meaning they use less fuel to heat your home, which can help reduce monthly energy bills over time.

If your existing boiler is over 10–15 years old, it may be operating at a much lower efficiency than today’s models. Even if it’s still working, an older boiler can cost more to run due to wasted energy, frequent repairs, or poor temperature control.

That said, a new boiler isn’t always necessary. At Gills Gas Solutions, we assess the condition and efficiency of your current system first and offer honest advice. If a service or repair is the most cost-effective option, we’ll tell you — and if a replacement would genuinely save you money in the long term, we’ll explain why.

Most boilers should be serviced once a year. An annual boiler service helps ensure your system is running safely, efficiently, and reliably, and can identify small issues before they turn into costly repairs.

Regular servicing can also help maintain your boiler’s efficiency, reduce energy bills, and is often required to keep the manufacturer’s warranty valid. For landlords, an annual service also supports compliance alongside gas safety checks.

At Gills Gas Solutions, we carry out thorough boiler servicing and provide honest, practical advice. If your boiler is in good condition, we’ll let you know — and if there are any concerns, we’ll explain your options clearly.

First, do not use electrical switches, naked flames, or appliances. If it’s safe to do so, turn off the gas supply at the meter, open doors and windows to ventilate the property, and leave the building straight away.

Once you’re outside and at a safe distance, contact the National Gas Emergency Service on 0800 111 999. This number is free and available 24/7 in the UK. Do not re-enter the property until you are told it is safe to do so.

After the emergency has been dealt with, a Gas Safe registered engineer should inspect and repair the issue before your gas is used again. At Gills Gas Solutions, your safety always comes first — if in doubt, treat it as an emergency and get help immediately.

The cost of a new boiler can vary depending on a few key factors, including the type of boiler you choose, the size of your home, and the complexity of the installation.

Generally, the price will include: The boiler unit itself Installation and labour Any additional pipework or parts System commissioning and safety checks

 Because every property is different, we don’t offer flat online prices — a boiler that’s perfect for one home may not be right for another. At Gills Gas Solutions, we provide free, no-obligation site visits and bespoke quotes based on your specific heating needs and home layout. This ensures you get the right boiler at a fair, reasonably priced cost without surprises.

There isn’t one single “best” boiler for every home, as the right choice depends on your property, usage, and budget. At Gills Gas Solutions, we specialise in installing and servicing boilers from trusted manufacturers, including Glow-worm, Vaillant, and Worcester Bosch.

These brands are well known for their reliability, energy efficiency, and excellent aftercare, with strong manufacturer-backed warranties that provide long-term peace of mind when installed and serviced correctly.

We’ll always recommend the boiler that best suits your home and budget, offering honest advice, professional installation, and ongoing support to ensure lasting performance and value.
