Questions about oil heating services answered
Honest answers to the questions we hear most from homeowners across Cumbria and Lancashire about oil heating, servicing, tank replacement, and switching to renewables.
Heating oil, also known as domestic fuel oil or kerosene, is a liquid fuel used to power oil-fired boilers and heating systems in properties that are not connected to the mains gas grid. It is stored in an oil tank on the property and delivered periodically by a fuel supplier. Heating oil is widely used across rural areas of Cumbria, Lancashire and the Lake District where gas connections are not available, and remains a reliable heat source, though many homeowners in these areas are now considering switching to more cost-effective and environmentally friendly renewable alternatives such as air source heat pumps.
Oil central heating is a heating system that uses an oil-fired boiler as its heat source, burning kerosene to heat water which is then circulated through radiators and to a hot water cylinder throughout the property. It is a common heating solution in rural and off-grid properties across Cumbria and Lancashire that are not connected to the gas grid. Oil central heating systems operate similarly to gas boilers in terms of the distribution of heat around the property, but require an oil storage tank on site and regular fuel deliveries.
The price of heating oil fluctuates with global energy markets and is typically ordered and delivered in bulk by a fuel supplier. Oil prices have been notably volatile in recent years, which is one of the key reasons many homeowners across Cumbria and Lancashire are now considering switching to renewable heating systems such as air source or ground source heat pumps. Unlike oil, heat pump running costs are more predictable and less exposed to fuel price volatility, making them an increasingly attractive long-term alternative for rural properties.
Heating oil stored in a well-maintained tank in good condition can last for up to 18 months to 2 years before degradation begins to affect its quality. Contaminated or degraded oil can cause boiler performance issues and increase the risk of blockages or damage to your system, which is why regular oil tank cleaning is important for properties that do not use their heating system heavily year-round. If your oil appears discoloured or your boiler is performing poorly, an oil tank clean and boiler service is worth considering.
Oil fired central heating can be more expensive to run than other heating systems, particularly given the volatility of oil prices in recent years. Running costs depend heavily on the efficiency of your boiler, the insulation levels of your property, and the current price of heating oil at the time of your delivery. For many rural homeowners across Cumbria and Lancashire, switching to an air source or ground source heat pump now offers a more cost-effective long-term solution, especially with the Boiler Upgrade Scheme offering up to £9,000 towards the cost of switching from oil.
An oil boiler works by burning kerosene or heating oil in a combustion chamber to heat a heat exchanger, which in turn heats water that is circulated through your central heating system and hot water cylinder. The burner draws oil from your storage tank via a fuel line and ignites it to produce heat. Modern oil boilers are significantly more efficient than older models, and a well-serviced oil boiler will operate reliably and safely for many years. As OFTEC registered engineers, we are qualified to service, repair, and replace oil boilers to the current industry standard.
An oil boiler service must be carried out by an OFTEC registered engineer to ensure it is completed safely and to the required standard. The service involves inspecting and cleaning the burner and heat exchanger, checking fuel lines and connections, testing combustion efficiency, inspecting the flue, and checking all controls and safety devices. Attempting to service an oil boiler without the appropriate OFTEC registration is not only unsafe but could invalidate your insurance. As OFTEC registered engineers, we carry out oil boiler services for domestic properties across Cumbria and Lancashire.
An oil boiler should be serviced at least once a year by an OFTEC registered engineer. Annual servicing keeps your boiler operating safely and efficiently, helps prevent unexpected breakdowns, and is typically a requirement of your home insurance and manufacturer warranty. We recommend scheduling your oil boiler service at the same time each year, ideally before the heating season begins, to ensure your system is in the best possible condition when you need it most. Our team is happy to carry out annual oil boiler services for properties across Cumbria and Lancashire.
Yes, and it is something we actively encourage for homeowners across Cumbria and Lancashire who are looking to reduce their long-term heating costs and move away from oil dependency. An air source or ground source heat pump can fully replace an oil boiler as your primary heat source, and the transition is often more straightforward than people expect. The Boiler Upgrade Scheme currently offers £9,000 towards the cost of installing a heat pump to replace an oil boiler, significantly reducing the upfront investment. We are always happy to have an honest conversation about whether switching to a heat pump makes sense for your property.
The cost of an oil tank replacement depends on the size of the new tank required, the complexity of the installation, and whether any additional groundworks or pipework connections are needed. We provide clear, itemised quotes for every oil tank replacement project and carry out all work to current OFTEC standards. If you are considering replacing your oil tank as part of a wider decision about your heating system, we are also happy to discuss the option of switching to a renewable heat source at the same time, which could make the overall investment more worthwhile.

Every installation we carry out uses the best brands and is backed by industry-leading accreditations and full public liability insurance.
