Try these two things before you call

Roughly one call in six is something you can fix in two minutes, and we would rather tell you that than charge you £99 for it.

  • Check the pressure gauge. If the needle is below 1 bar the boiler will lock out. Topping up via the filling loop usually brings it straight back.
  • Check the condensate pipe. In a cold snap the white plastic pipe running outside can freeze and shut the boiler down. A jug of warm — not boiling — water poured along it often clears it.

If neither works, or you can smell gas, stop and call us.

Faults we see most across the West Midlands

  • Pressure dropping every few days — a leak on the system, a failed expansion vessel, or a weeping pressure relief valve.
  • Heating works, hot water does not — usually the diverter valve or its actuator.
  • Boiler fires then cuts out — blocked heat exchanger, failed pump, or a sludged system starving flow.
  • Ignition lockout — spark electrode, gas valve or a PCB fault.
  • Radiators cold at the bottom — magnetite build-up, which is a system problem rather than a boiler one.
  • Banging or kettling — scale on the heat exchanger, common in Birmingham's harder water pockets.

Getting the diagnosis right first time

Over twenty years the pattern is consistent: most repeat visits come from someone swapping a part on a guess. We test rather than guess — flue gas analysis, flow and return temperatures, gas rate at the meter, electrical checks across the PCB. It takes longer on the first visit and saves you a second one.

Where the fault points to two likely parts, we will tell you both, tell you which we carry on the van, and tell you honestly what a fair repair bill looks like against the cost of replacing the boiler. If your boiler is over twelve years old and the repair is over £600, we will say so.

Parts and warranty

We carry common spares for Worcester Bosch, Vaillant, Baxi, Ideal, Glow-worm and Potterton, so a good share of repairs are finished on the first visit. Parts we fit are covered by a 12-month parts-only warranty.

When to stop repairing

A boiler past twelve years old, on its second or third major part, with a heat exchanger showing corrosion, is money going the wrong way. We will give you the repair price and the replacement price side by side and let you decide. We do not use scare tactics, and an engineer who condemns your boiler without showing you the reading is one to be wary of.

Answers

Boiler repair: common questions

How much does a boiler repair cost in Birmingham?

£99 covers the callout, full diagnosis and the first hour of work. Once diagnosed, we give you the total price for the repair before continuing, so you are never billed open-endedly.

Can you come out today?

We hold same-day slots for no heating and no hot water, and we run a 24/7 line for genuine emergencies such as gas leaks and uncontrollable water leaks. Call early in the day for the best chance of a same-day slot.

My boiler pressure keeps dropping. What is wrong?

Repeated pressure loss means water is leaving the system somewhere: a small leak on pipework or a radiator valve, a failed expansion vessel, or a discharging pressure relief valve. Topping it up daily is a symptom, not a fix, and it accelerates corrosion inside the boiler.

Do you repair all boiler makes?

We work on all domestic gas boilers and carry stock for Worcester Bosch, Vaillant, Baxi, Ideal, Glow-worm and Potterton. We also cover LPG appliances, which many engineers are not qualified for.

Is it worth repairing an old boiler?

As a rule of thumb, if the boiler is over twelve years old and the repair is more than a third of the cost of replacing it, replacement is usually the better spend. We will give you both numbers rather than push you one way.

What should I do if I smell gas?

Turn the gas off at the meter, open windows, do not touch electrical switches, leave the property and call the National Gas Emergency Service on 0800 111 999. Then call us to trace and repair once the supply is made safe.
