Work to include in your enquiry
This repair deals with the electronics of a gas boiler: the printed circuit board (PCB) that controls the fan, pump, gas valve and sensors, plus the wiring, fuses and connectors around it. Many faults that look like a dead boiler turn out to be a blown fuse, a loose connector or a faulty control outside the boiler, so the first job is to prove the board is really the cause.
Things to mention when you enquire
- A boiler with no lights at all
- Lockouts that clear when the power is switched off and on
- A boiler that ignores the thermostat
- A burning smell or discoloured marks visible on the outside
- The trip switch going when the boiler starts
Diagnosis and repair
Electrical faults are ruled out in order, from the wall socket to the board. The visit usually covers:
- Checking the mains supply, the fused spur and the fuse rating.
- Testing the room thermostat, programmer and any external controls and wiring.
- Inspecting the PCB and connectors for water damage, burnt tracks and loose plugs.
- Testing the outputs to the fan, pump, gas valve and sensors with a meter.
- Fitting the new board, configuring its parameters and running several heating and hot water cycles.
Not every dead boiler needs a new board
A blown fuse, a failed programmer, a flat thermostat battery or a damp connector can all make a boiler look completely dead. Replacing the board before those checks can mean paying for a part the boiler does not need. Boards are also model-specific, so the engineer needs the exact make, model and board part number before ordering.
Access and finishing up
Make sure the engineer can reach the boiler’s fused spur or isolator and the programmer or thermostat that controls it. If the boiler is in a loft or high-level cupboard, say so, because a board change needs space to work with the casing and fascia open.
A replacement board needs the correct part number and settings for the boiler. Find out whether water damage or another component caused the board to fail.
Guide prices for boiler PCB and electrical fault repair in Bishopbriggs
Budget around £150–£500 as a starting point. Your quotes may land above or below it. Replacing a fuse, a loose connector or a thermostat battery sits at the lower end. A new board for a common model sits in the middle. Boards for premium makes, or for older boilers whose parts are scarce, sit at the top, and some cost more than this range.
Have the engineer itemise the replacement part, labour and call-out charge, and confirm the VAT position. Allow 1–3 hours for the work itself; a board that has to be ordered means a second visit.
Information that speeds up a quote
Give the boiler make, model and age, plus any fault code. Say whether the display is on, blank or flickering, whether the spur is switched on and whether the fuse has blown. Mention any recent power cut, leak above the boiler or electrical work in the house.
Compare the scope of work before booking. Ask whether the quote includes testing the controls first, whether the board is new, refurbished or a manufacturer part, and how long it is guaranteed. Check how the price changes if the engineer finds the board is fine and the fault lies elsewhere.
Safety and regulations
Use an engineer on the Gas Safe Register with the right appliance and fuel categories for gas work. Ask to see the attending engineer’s photo ID and check their qualifications. Do not remove the boiler casing yourself. An external pump or room control may need a competent heating or electrical specialist without involving gas work; the qualifications needed depend on what is being disturbed.
A like-for-like component repair is not normally notifiable under Building Regulations. A boiler replacement, changed flue or new electrical circuit is a different job; ask what notification and certification apply.
If additional building work is proposed, check the approval requirements with East Dunbartonshire Council. If the job grows beyond a straightforward repair, confirm which approvals apply before the extra work starts.

Questions about boiler PCB and electrical fault repair
Check these points before agreeing to a diagnostic visit.
How can I compare quotes for boiler PCB and electrical fault repair in Bishopbriggs?
Fill in one enquiry form with your postcode, the boiler make and what the display and lights are doing. Up to four independent engineers covering Bishopbriggs may receive the repair enquiry. Responses depend on the repair needed and the engineers available. You choose whether to arrange a visit or accept a quotation.
Roughly how much is boiler PCB and electrical fault repair in Bishopbriggs?
We use £150–£500 as a UK guide. Engineers in Bishopbriggs price their own work. A fuse or connector costs far less than a new board, and boards for some makes cost much more than others. A written quote should list labour, parts, VAT and any call-out fee.
How do I know if my boiler PCB has failed?
Typical signs are a blank display with power at the spur, lockouts that clear after switching off, or a fan or pump that will not stop. These can also come from a fuse, a thermostat or wiring, so an engineer should test before replacing the board.
Can I swap a boiler PCB myself?
No. The board sits inside the casing alongside gas and mains-voltage parts, and only a Gas Safe registered engineer should work on it. A wrong or unconfigured board can also cause unsafe operation.
Why do boiler boards fail?
Common causes are age, heat cycles, damp from a small leak above the boiler, power surges and failed components such as capacitors or relays. Water reaching the board is one of the most frequent.
Are boiler PCBs still available for older boilers?
Often yes, either new or refurbished, but not always. Where the part is discontinued, the engineer should say so and talk through whether replacing the boiler makes more sense.
Ask who will remove the old parts and leave the work area dry and tidy. Keep the invoice, part details and any test or service record with the boiler manual.
