Alesta · Cooker hood repairs in London

Kitchen extraction, properly restored.

Careful diagnosis and repair for cooker hoods that have lost suction, become noisy or stopped responding. Tell us the make, model and fault so we can organise the right engineer.

Airflow and electrics considered together

A clear diagnosis for the cooker hood above your hob.

A cooker hood can sound as though it is working while moving very little air. Grease-loaded filters, a restricted duct, a tired motor, a failed capacitor or a control fault can create similar symptoms, so replacing parts before diagnosis is rarely the right starting point.

Tell us whether the hood extracts outside or recirculates, then share the make, model and exact behaviour. A photograph of the rating plate and installation helps us prepare for safe access around cabinetry, the hob and the electrical supply.

Fault diagnosis

Power, controls, fan speeds and accessible components are checked in a sensible sequence.

Motor and fan assessment

Noise, vibration, starting behaviour and airflow are used to assess the motor and impeller.

Controls and lighting

Switches, touch controls, indicators and cooker hood lights can be investigated.

Filters and airflow

Grease filters, recirculation filters and accessible duct connections are considered alongside the electrical fault.

Common reasons customers call

When the kitchen is no longer clearing steam and odours.

The fan runs without suction

The motor can be heard, but steam lingers and the airflow at the outlet feels unusually weak.

Speeds are intermittent

One setting has failed, the fan starts reluctantly or touch controls respond only occasionally.

Noise or vibration has changed

Rattling, scraping or a loud hum can point to the impeller, motor, mounting or an airflow restriction.

Lights or controls are dead

The hood has power problems, trips a circuit or no longer responds despite the supply being available.

Why Alesta for cooker hood repairs

A repair organised around the actual fault and installation.

Model and installation confirmed

Hood type, venting arrangement, dimensions and access help us match the visit appropriately.

Electrical safety first

A hood that trips, smells hot or has damaged wiring is isolated and assessed before continued use.

Compatible parts

Model-specific motors, capacitors, controls and lamps are identified rather than improvised.

Function checked

Agreed work is followed by checks of fan speeds, noise, controls, lighting and useful airflow.

How we carry out cooker hood repairs.

Every cooker hood repair begins with the installation and the symptom. We ask for the make and model, whether the hood extracts through a duct or recirculates through a carbon filter, and what happens at each fan speed. A photograph of the rating plate, controls and surrounding cabinetry can reveal useful access details. If the hood trips the electrics, smells hot or makes a scraping sound, we ask you to stop using it until it has been assessed.

At the property, the engineer makes the area safe and verifies the available supply before examining the hood. Grease filters and accessible duct connections are checked because restricted airflow can overload the system or imitate a motor fault. The engineer then works through the controls, lighting, fan speeds, motor starting behaviour and accessible wiring. Noise and vibration are considered alongside suction: a loose impeller or mounting can require a different response from a motor that hums but does not start.

If the fault is traced to a repairable component, the proposed work and any model-specific part are explained. Motors, capacitors, switches, electronic modules and lamp assemblies are not assumed to be interchangeable. Some common items may be resolved during the visit, while a precise manufacturer part may need ordering. Duct cleaning beyond the accessible connection, alterations to cabinetry and extensive fixed wiring are separate scopes and will be identified clearly if they are contributing to the problem.

After the agreed repair, the hood is reassembled with its filters correctly seated. The engineer checks available speed settings, controls, lighting, noise and useful airflow where the installation permits. For recirculating models, the condition and replacement interval of carbon filters can be explained; for externally vented models, an inaccessible or obstructed duct may need separate attention. You receive a straightforward account of the fault, the work completed and any practical maintenance step that can help the hood perform consistently.

Clear pricing

Cooker hood repair prices.

The final cost depends on the hood, access, diagnosis, labour and any model-specific replacement part.

Service scopePriceWhat affects the final price
Common cooker hood repairTypically £60–£150Hood type, fault, access and labour required
Diagnostic visitFrom £60Model, postcode, installation and whether specialist testing is required
Replacement partsQuoted separatelyManufacturer, model, availability and component cost

Typical pricing: Diagnostic visits can start from £60 and common repair work may fall between £60 and £150, but these are not fixed quotes. Parts, built-in access and complex electrical faults can increase the total.

How the service works

From weak extraction to a properly tested hood.

01

Send the model and fault

Share the hood type, make, model, installation and what happens at each setting.

02

Power and airflow are diagnosed

The engineer checks filters, controls and accessible components before recommending work.

03

The hood is reassembled and tested

Agreed work is checked across the available speeds, lights, noise and airflow.

Cooker hood repair FAQ

Before the engineer arrives.

Useful answers for planning a safe, efficient cooker hood repair visit.

☎ Call 020 3608 3976
What details should I provide before booking?

Share the make, model, installation type and exact symptom. Photographs of the hood, controls and rating plate can help identify access and compatible parts.

Why does the fan run but barely extract?

Grease filters, carbon filters or duct restrictions can reduce airflow, while a worn motor or damaged impeller can create a similar symptom. Diagnosis should consider both airflow and components.

Can a cooker hood motor be replaced?

Often it can, subject to safe access and availability of the correct model-specific motor or fan assembly. The sensible repair is confirmed after diagnosis.

Are replacement filters included?

Filters are not automatically included. Their type and condition are checked, then the correct grease or carbon filter can be identified and priced if replacement is required.

Does the service include cleaning the full duct?

No. The accessible connection can be considered during diagnosis, but specialist cleaning or alteration of concealed ductwork is a separate scope.

What should I do if the hood trips the electrics?

Stop using it and isolate it only if you can do so safely. Do not repeatedly reset the circuit; explain exactly what happened when you call.

What affects the cooker hood repair price?

The model, built-in access, fault, labour and cost of any compatible part all affect the total. The applicable visit structure is confirmed before booking.
