☎ Call 020 3608 3976Compatibility before installation
The fitting and the electrical point must suit each other.
A light can be physically attractive yet unsuitable for the existing support, wiring, location or control. Weight, dimensions, insulation, earthing, bathroom zones, dimming and ceiling construction all need consideration before the old fitting comes down.
We request photographs and product information first, then distinguish a like-for-like replacement from a new lighting point, circuit alteration, fault investigation or decorative making good.
Lighting fault checks
Supply, control, lamp and accessible fitting components are assessed before replacement.
Controls and dimming
Switch and dimmer compatibility is considered with the lamp and driver specification.
Testing and handover
Connections, protective measures and operation are checked for the completed scope.
Common reasons customers call
When a light needs qualified attention.
A new fitting needs installing
The customer-supplied or specified fixture must be checked against the existing point.
A light flickers or fails
The lamp, driver, control, connection or circuit needs evidence-led diagnosis.
A heavy fitting replaces a simple pendant
Ceiling support and safe fixing need confirmation before the installation proceeds.
The room needs a new lighting position
Cable routes, switching and finish access must be scoped as new electrical work.
Why Alesta for light fixtures
Electrical safety and visual finish considered together.
Specification reviewed early
Product data, weight, size, location and control type are checked before booking.
Support is not assumed
The electrician assesses whether the ceiling or wall fixing is suitable for the load.
Faults are diagnosed
A failed light is not replaced blindly where the circuit, switch or driver may be responsible.
Operation is checked
The completed fitting, controls and applicable electrical tests are confirmed at handover.
A safe lighting process
How we install or repair a light fixture.
Planning begins with clear images of the current light, ceiling or wall, switch and consumer unit, together with the new fitting specification. We check dimensions, weight, mounting plate, lamp or integrated LED type, driver, earthing class, dimming requirements and location. High ceilings, stairwells, fragile finishes and bathroom or exterior positions need specific access and equipment. If the request creates a new point rather than replacing an existing fixture, cable routing and making good are scoped separately.
On arrival, the electrician confirms the fitting and isolates the relevant circuit safely. The existing fixture is removed carefully and the accessible wiring, enclosure and support are inspected. Older conductors, heat damage, missing earth continuity, unsuitable connectors or a weak ceiling fixing can prevent immediate installation. These conditions are explained before additional repair, reinforcement or circuit work is undertaken. Decorative plaster roses and delicate surfaces are protected, but concealed damage cannot be guaranteed absent before removal.
A suitable mounting method is selected for the substrate and fitting load. Conductors are terminated with appropriate containment and strain relief, earthing is maintained where required and excess cable is managed without damaging insulation. Multi-part pendants, chandeliers or wall lights are assembled and aligned to the manufacturer instructions. Compatible lamps, drivers, transformers, switches and dimmers are used; mixing components without checking their load range can cause flicker, noise, poor dimming or premature failure.
The fitting is secured before power is restored. The electrician completes applicable checks, operates each control and observes the light for stable function. Where a fault rather than installation was booked, findings distinguish the lamp or fitting from the switch, driver or fixed circuit. Packaging and the removed fitting are handled only as agreed, while plastering, painting and specialist restoration remain separate unless listed. Handover covers operation, lamp replacement or driver limitations and any recommended follow-on electrical work.

Light fixture FAQ
Before the electrician arrives.
Useful answers about supplied lights, heavy fittings, dimmers, faults, access, finishes and pricing.
☎ Call 020 3608 3976Can you install a light fixture I have already bought?
Usually, if it is complete, suitable for the location and compatible with the supply, control, ceiling support and applicable UK requirements. Send the specification before booking.
Can a heavy chandelier use the existing fixing?
Not automatically. The electrician must assess the structure and mounting arrangement. Reinforcement or a specialist fixing may be required before the chandelier can be installed safely.
Why does my LED light flicker?
Possible causes include an incompatible dimmer, failing driver, loose connection, lamp issue or circuit fault. Diagnosis should identify the cause before components are replaced.
Can you move the light to a new position?
Yes where a suitable cable route and support can be provided, but this is new-point work rather than a simple replacement and may require openings and making good.
Do you work on bathroom lights?
Yes, provided the fitting and installation are appropriate for the bathroom zone and required ingress protection, circuit protection and bonding conditions.
Is plastering or painting included?
Only when expressly listed. A different canopy size or new cable route can expose old marks or require repair, so decorative work should be agreed separately.
What affects the final price?
Fitting complexity, quantity, assembly, weight, height, access equipment, ceiling support, circuit condition, controls, fault time and materials affect the quote.
