What an oil boiler service actually involves.

An oil service is a different job to a gas one, and it takes around 90 minutes. These are the six things that should be done. If they were not, you had a look over rather than a service.

1

Combustion readings, taken with an analyser

Combustion readings, taken with an analyser

Measured at the flue, not guessed. The readings show whether the burner is mixing oil and air properly, which decides how much oil it burns to keep your house warm.

2

Burner nozzle and oil filter

Burner nozzle and oil filter

The nozzle is the part that sprays the oil, and the filter keeps dirt out of it. Both are checked and changed where they need it, because a worn nozzle wastes oil and soots the boiler up.

3

The supply side: oil line, fire valve and tank

The supply side: oil line, fire valve and tank

The part a gas service does not have. We look over the oil line, the fire valve and the tank, because a supply problem shows up as a boiler that will not fire.

4

Heat exchanger and baffles cleaned

Heat exchanger and baffles cleaned

Oil leaves soot behind. Cleaning the heat exchanger and baffles keeps the heat going into your water and radiators rather than up the flue.

5

Flue, ventilation and condensate

Flue, ventilation and condensate

Flue checked, ventilation checked against what the boiler needs, and on a condensing boiler the condensate route checked for the fall that stops it freezing in January.

6

Cleaned, adjusted, and a straight answer

Cleaned, adjusted, and a straight answer

You are told plainly how the boiler is doing. Anything needing attention comes with what, why and what it costs, with no invented urgency.

Bridgend county and the Vale of Glamorgan as home ground, out to Cardiff one way and Neath and Port Talbot the other. Oil heating is mostly the rural homes off the gas grid in that patch, out in the villages and the Vale. Not sure whether you are in it? Send your postcode and we will tell you straight away.

LMB responded the same day to repair a gas problem I had. Other companies I contacted were unhelpful, and most of them actually declined the work. LMB were positive & engaging from the start, fixed the problem and charged a fair price. Highly recommended, ask for Lloyd.
