How We Handle Boiler Repairs
You Describe the Problem
Tell us what is happening -- no heating, no hot water, a leak, a strange noise, an error code on the display. Any detail helps. If your boiler is showing a fault code, have the code ready when you call.
We Book You In
For urgent breakdowns (no heating or hot water), we aim to get an engineer to you the same day wherever possible. For non-urgent faults, we usually book within a day or two.
Diagnosis
Our engineer inspects and tests your boiler to identify the exact fault. We do not guess. We do not start replacing parts on a hunch. Proper diagnosis saves you time and money.
Repair
Once we have identified the fault, we explain what needs doing and give you the cost before we start work. If we have the part on the van (which we usually do for common faults), we carry out the repair there and then.
Testing
After the repair, we run your boiler through a full test cycle -- checking ignition, flame stability, pressure, flue emissions, and all safety devices. We only leave when we are satisfied your boiler is operating safely and reliably.
Common Boiler Problems We Fix
No Hot Water or Heating
This is the most common reason people call us. Causes include a faulty diverter valve (particularly common in combi boilers), a failed pump, a seized motorised valve, a broken thermostat, or low system pressure. Sometimes it is as simple as a frozen condensate pipe in cold weather -- something that happens frequently in exposed pipework during Medway's colder months.
Boiler Losing Pressure
If you find yourself constantly topping up the pressure via the filling loop, there is usually a leak somewhere in the system. This could be a weeping pressure relief valve, a leaking heat exchanger, a dripping radiator valve, or a pinhole leak in the pipework. We locate the source and fix it properly rather than just topping up the pressure as a temporary measure.
Strange Noises (Kettling, Banging, Gurgling)
A boiler that sounds like a kettle boiling is usually suffering from limescale buildup or sludge in the heat exchanger. This is called kettling and it is particularly common in hard water areas. Medway's water supply comes from the chalk aquifers of the North Downs, so limescale is a genuine issue for many local homes. Banging noises can indicate trapped air or a faulty pump. Gurgling often means air in the system.
Error Codes and Lockouts
Modern boilers display error codes when they detect a fault and lock out for safety. Common codes we deal with include:
- Vaillant F28/F29 -- ignition failure (often a faulty electrode or gas valve)
- Vaillant F75 -- pressure sensor fault
- Worcester Bosch EA -- ignition failure
- Worcester Bosch 2970 -- flue/thermistor fault
- Baxi E119 -- low water pressure
- Baxi E133 -- ignition failure
- Ideal L2 -- ignition lockout
- Ideal FD -- fan fault
If your boiler is showing an error code, note it down and tell us when you call. It helps us prepare the right parts before we arrive.
Leaking Boiler
Water coming from your boiler is never something to ignore. Leaks can come from the pressure relief valve (often a sign of excessive pressure), internal seals, the heat exchanger, or pipe connections. Some leaks are straightforward fixes; others can indicate the boiler is reaching end of life. We diagnose the source and give you an honest assessment.
Pilot Light Keeps Going Out
If your boiler's pilot light will not stay lit (more common in older boilers), the cause is usually a faulty thermocouple, a blocked pilot jet, or a draught affecting the flame. In newer boilers with electronic ignition, the equivalent issue is ignition failure.
Radiators Not Heating Properly
Cold spots on radiators, radiators that are hot at the top but cold at the bottom (or vice versa), or radiators that do not heat up at all are common complaints. Causes include air in the system (solved by bleeding), sludge buildup (may need a power flush), a faulty pump, or a balancing issue. While these are not strictly boiler faults, they affect your heating and we fix them all.
Repair or Replace? An Honest Assessment
This is one of the most common questions our customers ask, and we always give a straight answer. Here is how we think about it:
Repair usually makes sense when:
- Your boiler is less than 10 years old
- The repair cost is under £400
- This is the first time it has broken down (or the first in a long while)
- The boiler is an A-rated model that is still efficient
- Replacement parts are readily available
Replacement usually makes sense when:
- Your boiler is over 12-15 years old
- Repair costs are approaching £400-500+
- The boiler has broken down multiple times in the past year
- It is an older, non-condensing model running at low efficiency
- Parts are becoming difficult to source (discontinued models)
- Your energy bills have been rising despite no change in usage
We will always give you both options with clear costs so you can make an informed decision. If repair is the sensible choice, we will say so. If replacement is better value in the long run, we will explain exactly why.
