Service Overview
Oil Boiler Installation & Servicing:
The Brief, In Plain English.
What It Is
Oil boiler installation, servicing and repair, Worcester, Grant, Firebird, Warmflow and Trianco. Tank-to-boiler pipework, internal and external boilers.
Who It's For
Rural homeowners and landlords on heating oil, replacing tired boilers, converting from older systems, or in need of proper OFTEC-registered annual servicing.
When You Need It
Replacing inefficient boilers (10+ years old), oil tank replacements, conversions from solid fuel, or annual servicing falling due.
Why It Matters
Oil boilers are mechanically different from gas, burners, nozzles, electrodes and pumps all need specific knowledge. OFTEC registration certifies that knowledge.
What Happens If You Wait
The Cost Of
Doing Nothing.
Oil boilers are unforgiving. Skip a service and you lose heat in January. Get it serviced badly and you lose money in fuel every month.
Risks Of Ignoring It
- →Sooted heat exchangers wasting expensive oil.
- →Worn nozzles causing flame failure and lockouts.
- →Tank issues, water ingress, sludge, leaks affecting supply.
- →Building Regs non-compliance from incorrect flue or fire valve install.
Common Mistakes Customers Make
- ×Booking a 'gas engineer' to service your oil boiler, they aren't OFTEC qualified.
- ×Skipping the annual nozzle change, fuel cost rises silently.
- ×Ignoring tank rust until contamination kills the burner.

Ask Yours
Is my boiler too old to service?
+
Most oil boilers can be serviced and kept running indefinitely with proper maintenance. We'll give an honest opinion on repair vs replace.
What's the difference between a service and a 'check-up'?
+
A proper OFTEC service strips, cleans and tests the burner including nozzle replacement and combustion analysis. A 'check-up' is just a visual.
Can you also handle the oil tank?
+
Yes, inspections, replacements, bunded tanks, fire valves and pipework, all within OFTEC scope and Building Regs compliant.
How much does an oil boiler install cost?
+
Most internal replacements fall between £3,200 and £5,500 fitted; external boilers slightly higher. Every quote is fixed before work begins.
What brands of oil boiler do you fit?
+
Worcester Bosch, Grant Vortex, Firebird, Warmflow and Trianco, all major brands, with manufacturer warranties registered.
How long does an oil boiler service take?
+
Typically 75–90 minutes including nozzle and electrode replacement, filter, combustion analysis, and full written certificate.
My oil boiler keeps locking out, what's wrong?
+
Usually nozzle wear, electrode misalignment, water in the fuel, or a failing photocell. All diagnosed and repaired same visit in most cases.
Do I need to drain my tank if it's contaminated?
+
Not always, water and sludge can often be pumped off and the tank polished. We assess and quote honestly before any disposal cost.
