Annual Boiler Servicing

Regularly serviced boilers have a longer lifespan, cost less to run, heat up faster and are checked to make sure they aren’t giving out any harmful gases into your home. You’ll risk invalidating your manufacturer warranty without regular boiler servicing, too.

The winter months can take their toll on your boiler system, so it’s worth getting your boiler serviced in the summer to make sure everything is running smoothly ahead of time and beat the rush.

By preparing in advance and getting your boiler serviced each year, you make sure it’s working well for the colder months and save any potential emergency call-outs for unexpected issues.


Keeping your home safe is a priority. A faulty or un-serviced boiler can increase the risk of dangerous consequences. This includes carbon monoxide leaks, or damage to your home caused by broken pipes or broken systems.

More efficient

A serviced boiler is a more efficient boiler. You’ll need regular check-ups to keep your boiler at tip-top health and to ensure it’s working as it should. Our team can offer thorough boiler servicing that causes minimal disruption to your home.

Peace of mind

The last thing you need is a boiler that stops working right when you need it most. You can live more comfortably knowing your boiler is working as it should be, before the Winter hits and it becomes much harder to get a service or new boiler installation.

Boiler replacements

Our team have performed boiler repairs in Southampton for old, modern and very uncommon boiler systems. We are confident that we can undertake repairs for any boiler system and deliver great results in a fast timeframe.

Boiler repairs may seem like a headache for many people – but our team understand what you need – a fast, effective solution with minimal disruption to your home.

Depending on the age and nature of the problem, boiler repair isn’t always the best option. Whilst we may be able to fix your broken boiler, you may be better suited to upgrading to a modern system that is likely to cause less problems for you down the line. Our team will provide honest, expert advice on your problem and only offer recommendations that are professionally driven.

Often, old boilers can also be much less efficient than modern boilers. In a time when energy prices continue to rise, it’s important to save pennies where we can – and this may involve upgrading your boiler system. Fortunately, we can help you with that.

Without regular servicing (where we add rust inhibitor), radiator pipes will start to rust from the inside, which can cause blockages, that make your house take longer to heat up, and can cause your boiler to break down.

A Powerflush is a special machine that we hook up to your central heating pipework, which flushes through and filters out the accumulated rust and sediment from your radiators and pipework. This improves the performance of your radiators and boiler, meaning it heats up faster, and costs you less to stay nice and warm.

Rather than a costly boiler replacement, a Powerflush might be all you need. Costs start from £380+VAT for a typical family home.

We know life gets in the way sometimes, but it’s important that your boiler gets serviced to keep you and your family safe.

Our team will check your boiler for multiple factors. This includes:

Correct gas pressure and flow, flue and combustion, electrical connections, fans, safety elements and much more.
