Moving to a home with an oil tank is one of those things that can catch you off guard. You’ve unpacked the boxes, started to get settled, and then you notice the tank sitting in the garden and wonder: what exactly do I do with that?
It’s a very common situation for people buying rural properties across Staffordshire, Cheshire, Shropshire and Derbyshire. Over 1.5 million UK homes rely on kerosene for central heating and hot water, yet if you’ve always lived somewhere connected to the mains gas grid, the idea of managing your own fuel supply can feel daunting at first.
It isn’t as complicated as it looks. Once you know what to check and how the system works, oil heating is a reliable and cost-effective way to keep your home warm. This guide takes you through the practical steps, from inspecting the tank on day one to placing your first delivery order.
If you’d like a broader introduction to how oil heating works, our ultimate guide to home heating oil is a good place to start.
What to Know When Moving to a Home with an Oil Tank
Oil heating works differently from gas. Instead of a continuous supply through a pipe, you own a fixed amount of fuel stored in a tank on your property. You’re responsible for ordering top-ups, maintaining the tank, and making sure the boiler is serviced regularly. It sounds like more work, but in practice it’s straightforward once you’ve got a reliable supplier and a routine in place.
Most domestic oil tanks hold between 1,000 and 2,500 litres, depending on the size of the property. The fuel inside is kerosene, sometimes called home heating oil or paraffin. It powers the boiler, which in turn heats your radiators and hot water, in exactly the same way a gas boiler would. The main difference is that you decide when to order, how much to buy, and who to buy it from.
There are a few key things to sort out when you first move in: checking the tank’s condition, getting the boiler serviced, finding out how much fuel is in the tank, and setting up a delivery account. We’ll walk you through each one below.
Step 1: Inspect the Condition of Your Oil Tank
Before you do anything else, take a close look at your oil tank. Checking for visible damage, corrosion, or signs of leakage is one of the most important things you can do when you move in. A tank in poor condition can lead to oil spills, which are expensive and environmentally harmful to clean up.
Most domestic oil tanks are made from plastic (HDPE) or steel. A well-maintained plastic tank typically lasts 15 to 20 years. A quality steel tank, if it’s properly cared for, can last considerably longer.
When you inspect the tank, look out for the following:
- Cracks, splits, or bowing in the outer shell (on plastic tanks)
- Rust, corrosion, or pitting on steel tanks
- Dark staining, oily patches, or wet ground around the base of the tank
- A strong smell of kerosene near the tank
- An uneven or sinking base beneath the tank (can indicate subsidence)
- A sight gauge or oil level monitor that’s cloudy, damaged, or missing
If you spot any of these warning signs, arrange for an OFTEC-registered engineer to carry out a professional inspection before you take delivery of any fuel. OFTEC, the Oil Firing Technical Association, is the trade body that regulates oil heating engineers in the UK. Using a registered engineer protects you and ensures all work meets current safety standards.
Step 2: Check Whether the Tank Meets Current Regulations
Oil tanks in the UK must comply with Building Regulations and environmental requirements around safe positioning and secondary containment. Tanks installed before 2012 may not fully meet current standards, and it’s worth getting a professional assessment if you’re unsure about your tank’s compliance.
Building Regulations Approved Document J sets out the positioning rules for domestic oil storage in England. The key requirements are:
- The tank must be at least 1.8 metres from any building, or at least 760mm if a fire-rated wall is present
- It shouldn’t be within 50 metres of a watercourse, borehole, or spring
- A drip tray or secondary containment must be in place in certain risk situations
A bunded tank provides the best protection. It’s a tank within a tank: the inner shell holds the fuel, while the outer shell acts as a secondary containment layer to catch any leaks. Most new domestic installations are now required to use bunded tanks, and they’re strongly recommended in areas near drainage, watercourses, or in flood-prone locations.
If your property has an older single-skin tank and you’re concerned about its position or condition, it may be worth replacing it with a modern bunded oil storage tank. We can advise on the right size and type for your property.
For a full overview of the rules that apply to domestic oil tanks, including positioning, containment, and inspection requirements, see our guide to heating oil storage regulations.
Step 3: Check the Boiler and Heating System
Even if the tank looks fine, you should have the boiler checked before relying on it. An oil-fired boiler should be serviced by an OFTEC-registered engineer at least once a year. If you don’t know when it was last serviced, book one as soon as possible after moving in.
Ask the previous owners for any service records they have. These will tell you the boiler’s age, when it was last inspected, and whether any parts have been repaired or replaced.
Key things to bear in mind:
- Most oil boilers have a lifespan of around 15 to 20 years, with efficiency declining as they age
- A boiler that hasn’t been serviced recently may have blocked filters, a dirty burner, or worn seals
- If the boiler is over 15 years old, it’s worth factoring in the possibility of a replacement when budgeting (typically £2,500 to £4,000)
- Always use an OFTEC-registered engineer for servicing, repairs, and any installation work
You can find registered engineers near you through the OFTEC directory on their website.
Step 4: Find Out How Much Oil is in the Tank
Check the oil level in your tank as soon as you move in. If the tank is low or empty, you’ll need to place a delivery before turning on the heating. Most local suppliers can deliver within 24 to 48 hours, and same-day emergency deliveries are available if you need fuel urgently.
Many tanks have a sight gauge, which is a clear tube on the side of the tank that shows the oil level. Some have an electronic oil monitor. If neither is working or available, an OFTEC engineer can check the level for you.
It’s important not to let your tank run completely dry. Running out of oil can allow air into the fuel lines, and the system may need bleeding by a qualified engineer before it’ll fire up again. This adds unnecessary cost and can leave you without heating at an inconvenient time.
If you move in and find the tank is empty or close to empty:
- Contact a local heating oil supplier to arrange a delivery
- The typical minimum order is 500 litres, which is usually enough for the average size property, to get you up and running
- If you’re moving in before winter, consider ordering more in one go to benefit from a lower per-litre price and carry you through until spring

How Much Oil Should I Order for the First Time?
For a first delivery, most households order between 500 and 1,000 litres. If you’re moving in ahead of autumn or winter, it makes sense to order more in one go. Larger orders carry a lower price per litre, and having a full or near-full tank heading into the colder months removes the risk of running low during a cold snap.
As a rough guide, a three-bedroom house will typically use between 1,000 and 1,500 litres of kerosene over a full heating year. Larger properties, or those with poor insulation, may use considerably more. Usage also depends on how often the heating’s on and whether the oil powers a cooker as well as the boiler.
A tip worth remembering: buying in late spring or early summer, when demand is lower, often gets you a better per-litre price than ordering at the start of winter when everyone else is doing the same. If your tank has the capacity, filling up in the warmer months can save a meaningful amount over the year.
Before placing your first order, it’s worth understanding how much it costs to fill a heating oil tank so you can budget accordingly.
Step 5: Set Up Your Heating Oil Deliveries
Once your tank and boiler are confirmed to be in working order, the next step is to arrange a regular supply. You can order on a one-off basis whenever your level drops low, or set up automatic deliveries so your tank’s topped up before it runs short.
The main options are:
- One-off orders: Order as and when your level drops to a certain point. Most suppliers offer online ordering or a phone line. Use our online calculator to get a quote and place an order quickly.
- Automatic top-up: A convenient option for busy households. Your supplier monitors your usage and arranges a delivery before you run low. At Stoddards, we offer an automatic delivery service that takes the guesswork out of managing your fuel. Contact the Stoddards sales team for more details on this.
- Flexible payment: Most suppliers offer a range of payment options, including pay per delivery, monthly billing, or a budget payment plan to spread costs across the year.

Tips for Managing Your Heating Oil Costs
Oil heating is cost-effective for off-grid properties, and there are some straightforward steps you can take to keep your costs under control from the start.
- Buy in spring or early summer when demand is lower and prices are typically more competitive. Read our guide to the best time of year to buy heating oil to make the most of seasonal price dips.
- Keep your tank at least a quarter full to minimise condensation inside the tank, which can lead to water contamination over time
- Install an oil level monitor so you always know exactly how much fuel you have and can order at the right time
- Service your boiler annually to keep it running efficiently and avoid fuel waste from poor combustion
- Use a fuel treatment additive to protect stored kerosene from contamination and extend its shelf life
We stock a range of fuel additives that can help protect your heating oil and keep your system running cleanly between services.

Frequently Asked Questions
Does the oil in the tank belong to the new owner when buying a house?
This depends on what was agreed during the sale. Some vendors include the remaining oil as part of the purchase price; others charge for it separately. It’s worth clarifying this with your solicitor before completion so you know exactly what level you’re inheriting and whether any additional cost is involved. Ask for a meter reading or sight gauge photograph at the point of exchange to avoid any disputes on moving day.
How do I know when my oil tank is empty?
Most tanks have a sight gauge on the side, which shows the current oil level visually. Some newer tanks have an electronic oil monitor or a smart gauge that can send alerts to your phone. If your tank doesn’t have a working gauge, check whether your boiler fires up normally: if the pilot light fails to hold or the system cuts out unexpectedly, the tank may be running low. If you’re not sure, an OFTEC engineer can check the level for you. You can also check the level yourself manually, if you need help with this, contact the Stoddards team.
What is a bunded oil tank?
A bunded tank is a double-walled oil storage tank. The inner tank holds the fuel; the outer shell provides a secondary layer of containment in case of a leak or spill. They’re the recommended option for most domestic properties and are required for new installations in many situations under current Building Regulations. Stoddards supplies a range of bunded oil storage tanks in various sizes to suit homes, farms, and commercial properties. Take a look at our guide to bunded oil tanks to learn more.
How often should I fill my oil tank?
This depends on your usage. Most off-grid households top up their tank two to four times a year. Many customers fill up once in late summer to benefit from lower seasonal prices, then again in mid-winter if needed. The best approach is to monitor your level and order before it drops below a quarter full, which keeps you comfortable and helps you avoid emergency delivery charges.
