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.

We have been using Aren Properly Services since 2022, and always receive amazing care when doing our boiler services, or any remedial works. They always go above and beyond and never try to rip you off like a lot of contractors out there. Highly recommend

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.

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!

We understand how concerning it can be when you smell gas or are unsure about the safety of your gas appliances. The skilled team at Aren Heating and Plumbing is here to provide peace of mind and ensure your safety.

At Aren, we take gas safety very seriously. All our engineers are Gas Safe registered and fully experienced in handling gas-powered appliances and systems, including gas hobs and cookers.

It is crucial to understand the dangers associated with gas appliances. We have a helpful blog post on essential detectors to keep you safe. If you notice a leak, and it is safe, turn off your gas supply at the mains tap near your gas meter.

Landlords and property managers must have an active ‘Gas Safety Certificates’ issued after a gas safety inspection of the boiler, flue, and appliances. This annual requirement ensures tenant safety. Visit our ‘Gas Safety Certificates’ page for more information.

Our Gas Safe Engineers Can Help With

Gas Installations

Aren Plumbing & Heating specialises in three types of installations: gas fires, cookers, and boilers from all the major manufacturers. Installation of only the most reliable and cutting-edge gear from the industry’s top manufacturers is just one way we ensure that we’re meeting, and exceeding, our clients’ expectations for quality and safety. We are known for our efficiency and attention to detail, which guarantees a high-quality final product for your installation and a spotless workspace thereafter. All of the components and installations we offer are expertly installed in record time, and we guarantee your satisfaction with both the products and our service. With our wealth of knowledge and expertise, we can guide you to the best option for your situation.

Gas Boiler Installation

Most gas boilers come with a guarantee that lasts anywhere from 3 to 12 years, depending on the model and manufacturer. In order to save money on gas costs and get the most bang for your buck in the long run, we advise choosing boilers with an ‘A rating’ for efficiency. Heating your house or company with an “A” rated boiler will save you money on gas without sacrificing comfort.

We only sell and install the most cutting-edge, dependable, and long-lasting boilers because we have an unrelenting dedication to both the quality of our products and the satisfaction of our clients. We combine top-quality equipment with unrivalled workmanship, and we cover all of our work with exceptional warranties so that you may have peace of mind. Some of the largest brands in the business, such as Baxi, Worcester, Vailant, and Potterton, are among the companies with whom we deal.

Gas Appliance Servicing and Installation

All gas appliances, including fireplaces, stoves, and boilers from any manufacturer, may be installed and serviced by Aren Plumbing & Heating. All of our work is of the greatest calibre, and we always leave the workspace neat and orderly after finishing a task.

Because we are Gas Registered Installers, you can be certain that all of our work adheres to the strictest possible safety and quality guidelines. It is a criminal offence to work on gas appliances without having a valid registration as a gas installer.

Utilising unregistered installers can endanger life.

Gas Safety Certificates

All gas appliances and flues need undergo a yearly gas safety inspection, which may only be done by a Gas Safe registered engineer, for the protection of the occupants. Once everything has been checked, you will receive a Landlord Gas Safety Record or Gas Safety certificate outlining all the work done.

According to the legislation, you must give your present renters a copy of your gas safety check within 28 days following the inspection or, in the case of new tenants, as away after the tenancy begins.
