Buying or replacing a cooker, oven, hob or washing appliance in Swansea requires a safety check. Check that the existing electrical supply suits the new appliance.
Does your appliance need a plug or hardwiring?
An appliance needs hardwiring only when its rating plate, power demand, circuit, and maker instructions require it. Hardwiring means a fixed connection to the electrical wiring.
Appliances that normally use a socket
A washing machine, dishwasher, and many extractor hoods normally plug into a suitable fixed socket. The socket must remain reachable and be in sound condition.
Do not feed the appliance through an extension lead or multi-way adaptor. Water appliances also need their valve, waste pipe, hoses, and hose route checked.
Check these points before pushing the appliance into place.
Cookers, hobs and fixed connections
Electric cookers, induction hobs, and some built-in ovens may need a dedicated circuit. This is a circuit reserved for one high-load appliance.
They may also need correctly sized cable, a cooker control unit, and a double-pole isolation switch. This switch cuts both live and neutral wires.
An electrician checks the appliance rating plate before making a connection. The plate usually shows power in kW.
The electrician compares that rating with the cable, circuit breaker, and maker instructions.
Never assume the old cooker cable is suitable. A replacement cooker or hob can have a different power rating. This can happen even when it fits the same kitchen gap. Check the new appliance instructions and circuit. Do not judge it by the old appliance.
The Institution of Engineering and Technology publishes BS 7671 IET Wiring Regulations. Electricians commonly call these the 18th Edition.
These rules guide cable choice, protective devices, earthing, and testing. An RCD or RCBO provides fault protection.
Neither device makes an overloaded or damaged cable safe.
Extractor hood fitting needs more than an available socket. Check whether the hood recirculates air or vents outside.
Confirm the maker's required gap above the hob. Check that the duct route works if outside ventilation is planned.
Some integrated hoods need a fixed connection. Others come with a plug for a suitable, reachable socket.
The electrical supply must be safely isolated before work starts. Keep cables clear of heat, steam, and sharp duct edges.
The hood must be fixed to a sound wall or cabinet before testing.
Check access, water and power before delivery
Before delivery, check dimensions, access, ventilation, electrical supply, water, and waste connections. This helps avoid a failed fitting visit.
The pre-visit checklist
Take photos and note the appliance model before asking for a quote. The model number and rating plate show the stated load and connection method.
This lets the electrician check the job without guessing.
- Measure the appliance recess, doors, stairs, and route from delivery point to the kitchen or utility room.
- Check that the socket, cooker switch, and water shut-off valve stay reachable after fitting.
- Confirm that the water inlet, waste pipe, and ventilation gaps match the maker instructions.
- Send the appliance model, rating plate details, and clear photos of the existing connection.
| Appliance | Usual electrical connection | Other services | Check before fitting |
|---|
| Washing machine | 13 A socket, if suitable | Cold water and waste | Valve access, drain height, leaks |
| Dishwasher | 13 A socket, if suitable | Water and waste | Hose route and cabinet clearance |
| Built-in oven | Plug or fixed connection | Ventilation space | kW rating and isolator |
| Electric hob or cooker | Often fixed cooker circuit | None, unless combined appliance | Cable, breaker and control unit |
Who fits appliances and what does it cost?
Use an electrician for fixed connections, new circuits, consumer unit changes, and electrical testing. Use a plumber or capable fitter for water and waste.
Use a Gas Safe registered engineer for gas work.
Ask for an itemised quote
A clear quote should split out labour, cable, materials, hardwiring, circuit extension, testing, certification, removal, and recycling. Retailer fitting packages often exclude repair work on existing electrics.
Ask what happens if the old circuit fails testing.
| Work type | Typical labour and materials | Extra work that changes cost |
|---|
| Washing machine or dishwasher connection | £80 to £160 | New valve, waste alteration, socket repair |
| Oven or hob fixed connection | £100 to £220 | New isolator, cable replacement, circuit tests |
| New cooker circuit | £250 to £600 | Cable route, floor lifting, consumer unit changes |
Certificates and responsible people
Electrical work should be inspected and tested when complete. The electrician may issue a Minor Electrical Installation Works Certificate or an Electrical Installation Certificate.
The type of certificate depends on the work. Some work may also need Building Regulations notification.
When arranging appliance installation in Swansea, check the technician's travel area. Ask whether the booking is a timed slot, an arrival window, or a same-day visit.
Same-day visits depend on availability. Ask in writing about the workmanship guarantee and its length.
Ask if a return visit is covered when a connection issue appears after fitting. Also ask who disconnects and removes the old appliance.
Removal, transport, and WEEE-compliant recycling may cost extra. They may not form part of the fitting price.
A clear booking confirmation should state the appliance model and agreed work. It should also list access needs, exclusions, and extra charges.
Extra charges can include parking, difficult access, or repair work found on site.
Avoid unsafe shortcuts during installation
Do not connect a high-load appliance through an extension lead. Do not hide an isolation switch behind a fitted unit.
Do not assume an old fuse rating suits a new appliance. A suitable visit includes safe isolation and an inspection of the connection point.
It also includes correct fitting and function testing. Washing machines and dishwashers need a leak check while filling and draining.
Safe appliance fitting route
1. Check label
Read kW and maker instructions.
2. Check supply
Check socket, cable, breaker, and isolator.
3. Fit safely
Connect, level, and route hoses.
4. Test
Check electrics, leaks, and start-up.
Gas appliances are a separate job
A Gas Safe registered engineer must do gas pipework installation, disconnection, or changes. An electrician may only do related electrical work, such as an ignition supply.
This service is not usually needed when an appliance plugs into a sound existing socket and no wiring changes are needed. It does not cover internal maker repairs. It also excludes gas work without a Gas Safe registered engineer. Complex plumbing changes need a plumber or kitchen fitter.
For fixed electrical work, ask who will make the connection. Ask if they can inspect, test, and certify work within their scope.
A recognised competent-person or electrical assessment scheme offers another way to check a contractor. The work must still suit the property and appliance.
After fitting an induction hob or built-in oven, the electrician should confirm safe isolation. They should also check terminal security, earthing, polarity, and the protective device where needed.
The appliance should then start in line with its instructions. Keep test results, certificates, and maker paperwork for future servicing or replacement.
Your questions answered
Does a new electric oven need hardwiring?
Not always. Check the maker instructions and rating plate.
Some lower-load ovens use a 13 A plug. Others need a fixed connection and a reachable isolator.
Can i use my old cooker cable for a new hob?
Only after an electrician checks the new hob's kW rating, cable size, and circuit breaker.
How much does cooker hardwiring cost in swansea?
A straightforward fixed connection often costs between £100 and £220. A new circuit, cable route, or consumer unit work can raise costs.
The total can reach between £250 and £600 or more.
Should a dishwasher be fitted by a plumber?
A plumber or capable fitter can connect water and waste when services are ready. An electrician is needed if the socket, fixed wiring, or circuit needs changing.
Does a washing machine need its own socket?
A washing machine should use a suitable fixed socket. Do not use an extension lead or multi-way adaptor.
Who can fit a gas hob in swansea?
A Gas Safe registered engineer must fit a gas hob. They must also alter its gas connection.
Will i get an electrical certificate?
You may receive a Minor Electrical Installation Works Certificate or an Electrical Installation Certificate. The certificate depends on the work done.
Book only after the circuit is confirmed
Confirm the appliance model, rating plate, access route, and connection type before arranging installation. Then get a written itemised quote.
The quote should cover the connection method, testing, materials, certification, and exclusions.
