Compare local quotes for boiler pump replacement and repair in West Lothian
A circulating pump that rattles or leaks needs checking alongside the surrounding pipework. Describe the noise and which radiators stay cold.
One enquiry about the job in West Lothian can reach up to four independent heating engineers, depending on the job and which engineers are free. The enquiry is free, and accepting a quote is your choice.
Work to include in your enquiry
This repair covers the circulating pump that pushes hot water from the boiler round the radiators. A failed or weak pump leaves the boiler hot and the house cold, and can make the boiler overheat. The pump head or the whole pump is replaced, and the system is checked for the sludge that often wears pumps out.
Things to mention when you enquire
- Heating that never reaches the radiators
- A humming, whining or rattling noise from the boiler
- Kettling noises soon after the boiler fires
- A pump that is warm but silent when the heating is called for
- A rusty stain below the pump
Diagnosis and repair
The engineer should diagnose the fault before deciding how much draining is needed. The visit usually covers:
- Confirming that the pump has power and that the spindle is turning.
- Reading the flow and return temperatures, the pump speed setting and any air in the circuit.
- Closing the pump isolation valves, or draining the system if none are fitted.
- Installing the replacement pump head or pump with new seals, then bleeding the circuit.
- Checking the pump speed and testing that every radiator heats evenly.
Pump head or whole pump?
Many pumps are built so that only the motor, called the head, is replaced while the body stays on the pipes, which is quicker and cheaper. On some combi boilers the pump is built into the hydraulic assembly and costs more to swap. Isolation valves either side of the pump make the job tidy; without them, part of the system has to be drained.
Access and finishing up
Say whether the pump sits on the boiler or on the pipes near a cylinder, and whether the boiler is in a cupboard with little working space. Tell the engineer if the pipework has isolation valves, because it changes whether the system has to be drained.
Access to working isolation valves can reduce the amount of draining needed. Ask whether the price includes refilling, air removal and circulation checks.
Guide prices for boiler pump replacement and repair in West Lothian
Budget around £180–£450 as a starting point. Your quotes may land above or below it. Replacing just a pump head with isolation valves in place sits at the lower end. A full pump on a system with no valves sits in the middle, because the system needs draining and refilling. A pump inside a combi’s hydraulic block can sit at the top. A system flush is separate work and can take the total above this range.
Have the engineer itemise the replacement part, labour and call-out charge, and confirm the VAT position. Allow 2–4 hours for the work itself; a pump built into the boiler can take longer.
Information that speeds up a quote
Describe the symptoms: cold radiators with a hot boiler, a noise, a leak or an overheating lockout. Give the boiler make and model and say whether the pump is built in or fitted on the pipework. Mention how old the system is and whether it has ever been flushed.
Compare the scope of work before booking. Ask whether the quote is for a new head or a full pump, whether isolation valves will be added, and whether a magnetic filter or a flush is recommended to protect the new pump. Check if the price includes inhibitor and refilling.
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 West Lothian Council. If the job grows beyond a straightforward repair, confirm which approvals apply before the extra work starts.
Visits and access in West Lothian
Put the postcode and the town or village on the form for work in West Lothian. Mention any permit needed for the repair visit. Include a picture of the pump and surrounding pipework if you can take one safely. The age of the house does not tell the engineer which boiler is fitted.

The free enquiry form takes a couple of minutes. We ask engineers who join for their insurance details and references, but check insurance and recent experience of similar jobs before you hire anyone. We pass on your enquiry. You deal with the chosen business for advice, pricing and the repair itself.

Questions about boiler pump replacement and repair
Check these points before agreeing to a diagnostic visit.
How can I compare quotes for boiler pump replacement and repair in West Lothian?
Fill in one enquiry form with your postcode, the boiler make and whether the radiators are cold while the boiler runs hot. Up to four independent engineers covering West Lothian 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 pump replacement and repair in West Lothian?
We use £180–£450 as a UK guide. Engineers in West Lothian price their own work. A new pump head costs less than a whole pump, and a system with no isolation valves needs draining first. A written quote should list labour, parts, VAT and any call-out fee.
How do I know my boiler pump has failed?
Common signs are a hot boiler with cold radiators, a loud whine or rattle, an overheating lockout, or a pump that is silent when the heating is on. A pump can also be fine but blocked with sludge, so an engineer should confirm.
Can a stuck pump be freed?
Sometimes. An engineer can free a seized spindle on pumps that allow it, but a pump that has seized once often fails again. They may recommend replacing it.
What speed should the pump be set to?
It depends on the system. The highest setting is not always best, because too high a speed can cause noise and flow problems, and too low leaves far radiators cold. The engineer should set it to suit your system.
Will a new pump fix a sludged system?
Not on its own. Black sludge wears pumps out, so a flush and a magnetic filter protect the new one. Ask for them in the quote.
Agree how old parts will be disposed of and how the work area will be left. Keep the invoice, part details and any test or service record with the boiler manual.
