Frequently asked questions
How often your boiler needs a service depends on its age and the make and model. However, it is generally advised to have your boiler serviced annually to make sure it operates safely and efficiently, and to identify any potential issues at an early stage before they escalate. Older boilers may need servicing more regularly, perhaps every six months. Boilers under warranty also usually need an annual service history for you to claim under warranty. We can provide you with the electronic records you need to sustain your manufacturer’s warranty.
Many boiler issues do not show any obvious symptoms at first, which is why we recommend regular servicing. However, symptoms such as strange clanking or buzzing noises, overheating, reduced heating output, leaks, fluctuating water pressure, or an unexpected increase in energy bills can signal underlying issues that need attention from a professional engineer. In general, the earlier the problems are addressed, the cheaper they are to fix. Please get in touch if you have any concerns, and we will send out a technician to diagnose and resolve the problem.
There are several things you can try to reduce your energy consumption and lower your utility bills, including installing a smart thermostat, improving insulation in your home and around your boiler, and regular servicing. However, if your boiler is more than 10 years old, the most cost-effective strategy may be to upgrade to a more energy efficient boiler model. We are happy to advise on a suitable model for your budget and heating needs.
If your boiler malfunctions or breaks down, it’s essential to contact a qualified heating engineer for repairs. Get in touch with us today and we’ll send someone out as a matter of urgency. Unless you are qualified, please refrain from attempting DIY fixes, and if you are concerned about safety (e.g. your carbon monoxide alarm has gone off), keep your boiler switched off and your home well-ventilated until the issue is resolved.
Good quality boilers are available to suit all household budgets. New combi boilers can cost from £1500-£3500 or more, depending on the size of your property and output of the boiler. A new system boiler is more expensive, costing from £2000-£4000 upwards, including installation. A combi boiler is a compact unit that provides heating and hot water on demand, whereas a system boiler works alongside a hot water cylinder to deliver hot water to multiple outlets simultaneously, and is a better choice for larger properties. When shopping for a boiler, look closely at its Energy Related Products (ERP) rating (formerly Seasonal Efficiency of Domestic boilers in the UK (SEDBUK) rating, if you haven’t purchased a new boiler for a few years). Those with higher energy efficiency may cost more upfront but deliver greater long-term savings on your energy bills.
