Frequently Asked Questions

Heating Engineers in South London

There are a number of ways you can tell your central heating system isn’t functioning properly, the first of which is that your radiators take a while to heat up, they don’t heat up at all, or they make rattling noises. Your hot water never quite being hot enough, whether through the taps, pipes, or shower, is another sign that your system may be in need of a repair.

Unfortunately, yes. If your radiators aren’t heating up properly or your hot water tap takes longer to get and stay warm, you could see your energy bills increase with less energy output in your premises. This is why we recommend yearly servicing, and calling one of our engineers as soon as you notice any of the tell-tale symptoms, to save you money in the future.

Yes, there is! A properly maintained central heating and boiler system can last between 10 and 15 years, and this does include regular servicing. We recommend you should have your central heating system serviced once a year, and this servicing can help us identify any repair work that needs to be completed in order to ensure the optimum running of your home or business premises.

As a landlord, you are responsible for the safe working order for all gas appliances on your property or properties, every 12 months. Once we have completed your checks, you will be issued with a certificate, which you must keep for 2 years.

A power flush is where a low pressure but high water flow pump is connected to your central heating system and is pumping water through at high speed. With a combination of some essential chemicals, the power flush can dislodge and break down any materials, such as limescale or black sludge and leave your system working at 100% maximum efficiency again.
