Heating fault diagnosis and service routes
Central Heating Services
Report loss of heating or hot water, boiler faults, cold radiators, pressure problems and heating-control issues.
Send the postcode, fuel, appliance or heat source, system details and exact symptoms. We will use the information to identify the appropriate engineer and visit scope before attendance.
The quick answer
What does a central heating service cover?
Central heating service is a broad customer term. It can mean investigating a boiler fault, tracing loss of circulation, dealing with one cold radiator, checking a control problem or arranging planned maintenance. These jobs do not all require the same visit.
This page helps you choose the closest route. Tell us what has stopped working, what still works and what type of system you have. The enquiry can then be matched to the appropriate competence, likely diagnostic work and access requirements.
Choose the closest route
Which heating service do you need?
Selecting the closest description prevents a failed booking and keeps planned maintenance separate from fault diagnosis, certification and installation work.
Heating or hot-water fault
The boiler or heat source has stopped, locks out, loses pressure or is not delivering heat or hot water.
Planned boiler service
The boiler is operating and you want routine inspection and servicing rather than investigation of a known breakdown.
Boiler replacement or installation
You are replacing an existing boiler, changing its location or planning a new heating installation.
Radiators and circulation
One or more radiators are cold, slow, noisy, leaking or heating unevenly, or the system appears poorly balanced.
Controls and zoning
A thermostat, programmer, motorised valve or heating zone is not responding as expected.
Landlord gas safety record
You need the annual safety check and record for relevant landlord-provided gas appliances and flues.
Useful information before attendance
Describe the system, not only the symptom
A short, precise fault history helps determine whether the enquiry needs gas, electrical, plumbing, control or wider heating-system competence. Do not remove covers or dismantle equipment to obtain details.
- Full postcode and property type
- Natural gas, LPG, electric or other heat source
- Boiler or heat-source make and model
- Combi, system, regular or other arrangement if known
- Fault code and pressure-gauge reading
- Whether heating and hot water work independently
- Number and location of affected radiators or zones
- Thermostat, programmer and smart-control details
- When the fault started and whether it is intermittent
- Photographs of the appliance display and visible leak
- Previous work or recurring faults
- Parking, keys, tenant notice and access restrictions
From enquiry to repair decision
What happens after you report a heating fault?
The outcome of diagnosis cannot be promised in advance. The process separates the initial visit from any additional parts, specialist work or return attendance.
Send the details
Describe the system, symptoms, postcode, access and anything already tried.
Confirm the route
We check the relevant trade, competence, visit purpose and quotation basis.
Attend and diagnose
The engineer inspects within the agreed scope and explains the evidence found.
Agree further work
Parts, extended investigation and additional labour are quoted before authorisation.
Keep the record
Retain invoices, service records, safety records and remedial evidence for the system.
Clear scope and pricing
Diagnosis, servicing, repairs and certification are different jobs
The cost depends on the system, fault, engineer route, access, location, parts and time required. A written quotation or price basis should identify what the initial visit includes and what would be additional.
Confirm before the appointment
- The problem or planned service requested
- The appliance, fuel and system included
- The initial visit or inspection basis
- Access, parking and tenant arrangements
- Whether a certificate or written record is required
- Any known exclusions or limitations
Usually separate unless written in
- Replacement parts and manufacturer-specific components
- Extended fault tracing or work on another system
- System cleaning, flushing or water treatment
- New controls, pipework, radiators or appliance replacement
- Scaffolding, lifting, specialist access or making good
- A return visit after parts or further authorisation
Gas work and engineer competence
Gas Safe registration must match the work being carried out
HSE states that gas work within the Regulations must be carried out by a Gas Safe registered business and engineer. The engineer’s current ID card shows the work categories they are qualified to undertake. A general description such as plumber or heating engineer does not by itself prove gas competence.
Check the identity card
The front identifies the engineer and expiry date; the reverse lists the categories of gas work they are qualified to undertake.
Match the appliance and fuel
Boilers, cookers, fires, natural gas, LPG and commercial work can require different listed categories.
Keep safety routes separate
A repair invoice or boiler service record is not automatically a landlord gas safety record or a certificate for unrelated work.
Smell gas, suspect carbon monoxide or face immediate danger?
Use the emergency route, not the booking form
If you smell gas or suspect carbon monoxide, turn off appliances where safe, open doors and windows, avoid flames and electrical switches, and leave the property if necessary. Call the National Gas Emergency Service on 0800 111 999. Call 999 for fire or immediate danger and seek urgent medical advice where carbon monoxide exposure is suspected.

Boiler servicing and landlord gas safety checks are not interchangeable
HSE guidance distinguishes ongoing maintenance from the annual landlord gas safety check. Landlords must arrange maintenance and an annual check for relevant gas appliances and flues they provide, using a Gas Safe registered engineer qualified for the work.
A routine boiler service may support maintenance, but it does not automatically create the required landlord gas safety record. State clearly whether you need servicing, fault repair, the annual safety check and record, or a combination quoted in writing.

Common questions
Central heating service FAQs
Straight answers about fault reporting, boiler servicing, radiators, parts, Gas Safe competence, emergencies and coverage. These visible answers match the FAQ structured data on this page.
What does a central heating service enquiry cover?
A central heating enquiry can cover loss of heating or hot water, boiler faults, cold or uneven radiators, pressure problems, noisy circulation, leaking heating components and control faults. The first step is to describe the system and symptoms so the appropriate engineer and visit scope can be confirmed.
Is a boiler service the same as a central heating repair?
No. A planned boiler service is routine maintenance and safety checking for an appliance that is operating. A repair visit investigates a known fault or failure. If the boiler is not working, repeatedly loses pressure, locks out or shows a fault code, describe it as a repair enquiry rather than booking only a routine service.
Can Upkeepone investigate radiators that are cold or uneven?
Yes, radiator and circulation symptoms can be submitted as a central heating enquiry. State whether one radiator or the whole property is affected, whether the radiator is cold at the top or bottom, whether valves move, and whether the boiler and hot water still operate. The cause must be diagnosed before a repair or cleaning method is recommended.
Do central heating repairs include parts?
Not automatically. The agreed visit covers the scope confirmed in the quotation. Replacement parts, further investigation, additional labour and a return visit are separate unless they are expressly included in writing. The engineer should explain the finding and proposed work before additional costs are authorised.
Must a central heating engineer be Gas Safe registered?
Gas work within the scope of the Gas Safety regulations must be carried out by a Gas Safe registered business and an engineer qualified for that type of work. The engineer's current ID card shows the work categories they are qualified to undertake. Non-gas heating work may require a different competent trade route.
What information should I send with a heating repair request?
Send the full postcode, property type, fuel, boiler or heat-source make and model, system type if known, controls, exact symptoms, fault code, pressure reading, when the problem started and what is still working. Include clear photographs, access details and any tenant, parking or deadline restrictions where relevant.
What should I do if I smell gas or suspect carbon monoxide?
Do not use an online booking form as an emergency route. Turn off appliances where it is safe to do so, open doors and windows, avoid flames and electrical switches, leave the property if necessary and call the National Gas Emergency Service on 0800 111 999. Call 999 where there is fire or immediate danger and seek urgent medical help if carbon monoxide exposure is suspected.
Which areas does Upkeepone cover for central heating enquiries?
London, Essex and Kent are the priority areas for regular central heating enquiries. Hertfordshire, Surrey, Buckinghamshire, Berkshire and Sussex are also covered, with other UK locations considered by request. Attendance depends on the postcode, fuel, system, access, travel and appropriately qualified engineer availability.
