Your Local Boiler Repair Specialist – Vince at GC Plumbing

Boiler breakdown? Get someone who actually enjoys finding the fault.

I'm Vince from GC Plumbing, a local Gas Safe engineer specialising in boiler breakdowns, fault finding and boiler repairs across South West London and Surrey.

Boiler repairs are a big part of what I do. From an intermittent fault that's been driving you mad for weeks to no heating, no hot water, leaking boilers, pressure problems and difficult fault codes, my aim is to properly diagnose the problem and get your boiler running again — not simply tell you that you need a new one.

I repair boilers throughout the SW and KT postcode areas, including:

• Boiler repairs in Surbiton & Tolworth

• Boiler repairs in Kingston

• Boiler repairs in New Malden

• Boiler repairs in Chessington

• Boiler repairs in Thames Ditton & Long Ditton

• Boiler repairs in Esher

• Boiler repairs in Epsom

• Boiler repairs in Wimbledon

• Boiler repairs across South West London & Surrey

I work on Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Potterton and many other domestic gas boilers, covering everything from straightforward breakdowns to difficult and intermittent faults.

No heating? No hot water? Boiler won't fire up? Fault code showing?

Boiler Fault Codes & Error Messages

Is your boiler showing a fault code or constantly locking out?

Modern boilers display a fault code or error code when they detect a problem. The code can help identify which part of the boiler needs checking, but it doesn't always mean that a particular component needs replacing.

At GC Plumbing, I provide boiler fault finding and breakdown repairs across Surbiton, Tolworth, Kingston, New Malden, Chessington, Esher, Epsom, Wimbledon and surrounding South London & Surrey areas.

Common boiler fault code problems include:

• Boiler showing a fault or error code

• Boiler won't fire up

• Boiler repeatedly locking out

• Boiler works after a reset but the fault keeps returning

• Ignition or flame failure

• Low water pressure faults

• Overheating faults

• Fan or air-pressure faults

• Pump and circulation problems

• Temperature sensor faults

• Gas valve or ignition problems

• Heating working but no hot water

• Boiler suddenly losing heating and hot water

I diagnose fault codes on many popular boiler makes including Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm and Potterton.

A fault code is a useful starting point, but proper testing is important to establish why the fault has occurred before replacing parts.

Heating Working But No Hot Water?

Radiators hot but no hot water from your taps?

If your central heating is working but you have no hot water, the boiler itself is clearly capable of producing heat, but there may be a problem with the components that control or produce your domestic hot water.

This is a common combi boiler fault and doesn't necessarily mean that your boiler needs replacing.

Possible causes can include:

• Faulty diverter valve

• Blocked or restricted plate heat exchanger

• Faulty flow sensor or flow turbine

• Hot water temperature sensor / NTC fault

• Boiler not detecting when a hot tap is opened

• Low or fluctuating hot water flow

• Electrical or PCB fault

• Hot water getting hot then cold

• Boiler firing for heating but not firing for hot water

At GC Plumbing, I diagnose no hot water faults on Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Potterton and other domestic boilers throughout South West London, Surbiton, Tolworth, Kingston, New Malden, Chessington, Esher, Epsom and the surrounding KT postcode areas.

If your radiators are getting hot but your taps or shower are cold, I can fault-find the boiler, identify what's actually causing the problem and advise on the most economical repair.

Blocked Plate Heat Exchanger?

Hot water going hot, cold, then hot again?

A blocked or restricted plate heat exchanger is a common cause of hot water problems on combi boilers. Over time, scale, sludge and debris can restrict the small waterways inside the heat exchanger and prevent heat being transferred efficiently to your hot water.

Common signs of a blocked plate heat exchanger include:

• Hot water going hot and cold

• Shower temperature constantly fluctuating

• Hot water starts hot then turns cold

• Boiler temperature rising quickly when a hot tap is running

• Boiler firing and cutting out

• Poor or reduced hot water performance

• Heating working normally but hot water not working correctly

• Hot water taking longer to heat up

At GC Plumbing, I regularly diagnose and replace blocked plate heat exchangers on Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm and other combi boilers.

If your boiler's hot water is constantly changing temperature, don't automatically assume you need a new boiler. I can diagnose the cause and, where required, replace the plate heat exchanger to get your hot water working correctly again.

Boiler Leaking Water?

Found water dripping or pooling underneath your boiler?

A leaking boiler should be investigated before a small leak causes damage to other components. Water can escape from several different parts of a boiler, and the location of the leak can help identify the cause.

Common causes of boiler leaks include:

• Leaking pressure relief valve (PRV)

• Faulty or discharged expansion vessel

• Leaking pump

• Worn seals and O-rings

• Leaking diverter valve

• Leaking plate heat exchanger

• Main heat exchanger leaks

• Internal pipe or connection leaks

• Boiler pressure rising too high and discharging water

• Condensate leaks

At GC Plumbing, I diagnose and repair leaking boilers throughout South West London, Surbiton, Tolworth, Kingston, New Malden, Chessington, Esher, Epsom and the surrounding KT postcode areas.

Boiler Flue Problems

Problems with your boiler flue or flue connection?

The boiler flue is an important safety component that carries combustion products safely from the boiler to outside. Problems with a boiler flue should always be inspected by a Gas Safe registered engineer.

Boiler flue problems can include:

• Leaking boiler flue

• Water entering around the flue

• Damaged or deteriorated flue seals

• Loose or incorrectly fitted flue joints

• Flue not correctly supported

• Damaged flue terminal

• Incorrect flue fall or installation

• Problems with flue extensions

• Corrosion or deterioration

• Boiler fault codes associated with airflow or combustion

I can inspect and diagnose boiler and flue problems, identify whether repairs or replacement components are required and ensure the boiler and flue are operating safely.

If you suspect a problem with your boiler flue, don't dismantle or attempt to repair it yourself.

Smell of Gas or Suspect a Gas Leak?

Boiler, gas pipe or cooker leaking gas?

If you can smell gas in your home or suspect a gas leak from a boiler, cooker, hob or gas pipework, it should never be ignored. Gas leaks can occur from appliances, joints, pipework and components such as a boiler gas valve.

Gas problems I can investigate include:

• Smell of gas near a boiler

• Suspected faulty or leaking boiler gas valve

• Gas pipe leaks

• Leaking gas fittings or joints

• Gas cooker or hob leaks

• Gas smell after an appliance has been installed or disconnected

• Suspected leaks from older gas pipework

• Gas pressure and tightness testing

• Locating and repairing gas leaks

• Boiler gas supply and combustion faults

I'm Gas Safe registered and carry out gas fault finding, tightness testing and gas repairs across South West London, Surbiton, Tolworth, Kingston, New Malden, Chessington and surrounding KT postcode areas.

If You Can Smell Gas Now

If you currently smell gas, don't use electrical switches, naked flames or anything that could create a spark. Open doors and windows where safe to do so, turn off the gas supply at the emergency control valve if you know how and can do so safely, and call the National Gas Emergency Service immediately on 0800 111 999.

Once the immediate situation has been made safe, GC Plumbing can investigate and repair faults with boilers, gas pipework, cookers and other domestic gas appliances.

Got an Older Boiler? Parts No Longer Available?

Been told your boiler is obsolete or can't be repaired?

Just because a boiler is old doesn't always mean it needs to be replaced. One of the biggest problems with repairing older boilers is finding parts once manufacturers discontinue them.

At GC Plumbing, I have access to a large local supply of new, refurbished and quality used boiler parts, including components removed from boilers specifically for spares. This means I can sometimes source parts for older boilers that are no longer readily available through normal suppliers.

I can source many older boiler components including:

• Discontinued boiler parts

• Boiler PCBs

• Gas valves

• Fans

• Pumps

• Main heat exchangers

• Plate heat exchangers

• Diverter valves

• Hydraulic blocks

• Flow sensors and turbines

• Pressure relief valves (PRVs)

• Sensors, switches and controls

• Various older and hard-to-find boiler components

I work on older Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Potterton and other domestic boilers.

I also have access to locally stocked parts, which means I can sometimes obtain hard-to-find components outside normal supplier opening hours, subject to availability.

If another engineer has told you “they don't make the part anymore”, it may still be worth checking before replacing the entire boiler.

Got an old boiler with an obsolete or discontinued part? Contact Vince at GC Plumbing with the boiler make, model and fault and I'll see what can be sourced.
