 Trustindex verifies that the original source of the review is Google. Have used them twice now, once to disconnect/relocate radiators and another time to relocate the boiler. In both cases the team managing things have been very professional, quick but thorough, and clear re what was to be done. Particular thanks to James, Ronan, and Nick. Prices are fair for good quality work and service, will definitely reach out again for any other jobs.

 Trustindex verifies that the original source of the review is Google. I had an issue with my HIU. I was able to quickly arrange a booking with Aren. Their onsite engineer was polite, friendly and punctual. He fixed the problem quickly and gave me some basic advice on what to look out for to help troubleshoot future problems. I would highly recommend Aren Heating and Plumbing.

 Trustindex verifies that the original source of the review is Google. Quick, clean and efficient. Very pleased and will be using Aren again. Ronan (the plumber) worked hard and fast to finish job inside 1 hour which kept the cost down for me, when he could have easily relaxed and stretched it out. Thanks!

Key information

FAQ

What is a Baxi boiler service?

A Baxi boiler service is an annual safety and performance check carried out by a Gas Safe registered engineer. We inspect all the key components including the heat exchanger, burner, electrodes and gas valve, test gas pressure and flue gas readings, clean any parts that need it, and check the system pressure and controls are working correctly. We also carry out a combustion analysis to confirm the boiler is burning gas cleanly and not producing dangerous carbon monoxide levels. You’ll get a digital copy of the service report once we’re done, which is useful for warranty purposes and if you ever sell the property.

How often should my Baxi boiler be serviced?

Once a year. Baxi requires annual servicing to keep your manufacturer warranty valid (most Baxi boilers come with a 7 or 10 year warranty depending on the model and installer). Skip a service and you risk voiding the warranty, even on a boiler that’s only a couple of years old. We recommend booking your service in summer when engineers are less busy and you’ll have time to fix any issues before winter. Leaving it until October or November is risky, because if your boiler fails the service, you might be without heating during the cold months while parts are ordered.

Why should I service my Baxi boiler?

There are three main reasons. First, safety. A service picks up problems like carbon monoxide leaks, cracked heat exchangers or worn seals before they become dangerous. Carbon monoxide is a silent killer and a faulty boiler is one of the main causes in UK homes. Second, efficiency. A serviced boiler runs cleaner and uses less gas, which keeps your bills down. A poorly maintained boiler can use up to 10% more gas to produce the same heat. Third, warranty. Baxi requires annual servicing to honour their warranty, so skipping one could cost you thousands if something major fails later. Regular servicing also extends the life of your boiler, often by several years.

How long does a Baxi boiler service take?

Most Baxi boiler services take 45 minutes to an hour. Newer Baxi 800 and Platinum models tend to be quicker because they have built-in diagnostics that speed up the checks. Older boilers, or ones that haven’t been serviced for a while, may take a bit longer (sometimes up to 90 minutes) because there’s more cleaning involved and we may need to address issues that have built up. We won’t rush the job. A proper service catches problems early, which is the whole point of having one done.
