Costs, Quotes and Booking

 

How much does an electrician cost in Greenock or Largs?

The price depends on the job, access and any tests we need to do. A small repair, new circuit and full rewire each take a different amount of work. So a broad hourly rate may not tell you what your job will cost. DTEC Electrical gives clear quotes for planned work. If tests find another fault, we explain it before we suggest more work.

 

Do you offer free quotes for electrical work?

Yes. DTEC Electrical offers free quotes for planned work. Tell us what you need, where the property is and when you hope to have the job done. Photos may help us see the site. Some jobs need a visit or tests before we can give a firm price. Your quote will set out the work we propose and its cost.

​

Can I book an emergency electrician outside normal hours?

Yes. DTEC Electrical takes calls for urgent electrical faults 24 hours a day. Call 07882 372474 if you smell burning, see sparks or have lost power in your home. Tell us what has happened and which rooms or circuits are affected. We will discuss the next safe step and whether an emergency visit is needed. Call-out terms can be explained before a visit.

​

Faults and Electrical Safety

 

Why do my electrics keep tripping?

A breaker or RCD may trip due to a faulty appliance, damp, worn wiring or a fault on the circuit. The trip tells you there is a problem, but it does not show the exact cause. We can test the affected circuit, trace the fault and explain the repair. Do not keep resetting a device that trips again, as the fault may still be present.

​

What should I do if I lose power at home?

First, check if nearby homes have lost power too. Your power supplier may have news of an outage. If the loss seems to be in your home only, look at the fuse box if it is safe to do so. Do not touch parts that look burnt or wet. If a breaker trips again, or you smell burning, call an electrician for help.

​

Is a flickering light always caused by the bulb?

No. A loose bulb may flicker, but the cause could also be the light fitting, a loose wire or a circuit fault. If a new bulb does not help, or several lights flicker, have the fault checked. A fitting that is hot, burnt or making noise needs prompt care. We can test the light and its circuit to find the cause.

​

What should I do about a warm socket or a burning smell?

Stop using the socket or item at once. If it is safe, switch off the affected circuit and call an electrician. Heat, marks, sparks and a burning smell can point to a serious fault. Do not plug the item back in to test it. Tell us what you saw or smelled, when it began and whether the socket has stopped working.

​

Can damp weather affect electrics in coastal homes?

Yes. Water can reach outdoor lights, worn sockets and loose seals. This may lead to faults after rain, but damp weather alone does not prove what is wrong. In coastal towns such as Largs and Greenock, we check the fitting and the circuit before we advise a fix. The right repair depends on where the water has reached and what the tests show.

​

Rewiring and Fuse Boxes

​

How do I know if my house needs rewiring?

Signs can include repeat faults, damaged sockets, lights that flicker or wiring that has been changed many times. An old home does not always need a full rewire. We can inspect and test the wiring, earthing and circuit protection. We then explain what we found and whether a repair, part rewire or full rewire makes sense for the home.

​

Can you replace an old fuse box without rewiring the house?

Often, yes. A new fuse box, also called a consumer unit, can often work with sound existing wiring. We need to test the circuits and earthing first to see if they are fit to connect. If we find a fault, we will explain it before work goes ahead. A new box alone will not fix a fault that is still present on a circuit.

​

Does an old fuse box always need replacing?

No. Age alone does not tell us whether a fuse box must be changed. Its state, the safety devices it has and the circuits it serves all matter. We can check the box and explain what it can and cannot protect against. If we advise a fuse box upgrade, we will explain the reason, any faults found and what the work will involve.

​

How long does a house rewire take?

It depends on the size of the home, how we can reach the old wires and whether you will live there during the work. A part rewire will often take less time than a full one. We assess the home before giving a schedule. We will explain which rooms need access, when power may be off and what work may follow the wiring.

​

Will I receive tests and paperwork after electrical work?

We test work when it is done and give the right documents where they are required. The tests and paperwork depend on the job. A new circuit may need different records from a small repair. Ask us what applies to your work before it starts. We can explain what we will test and what you will receive when the job is complete.

New Work and Local Services

 

Can DTEC Electrical add sockets or circuits during a renovation?

Yes. We add sockets and carry out wiring changes for new kitchens and other home projects. First, we check whether the old circuit and safety devices are fit for the new work. It also helps to plan where you will use lamps and appliances before work begins. If the job needs a new circuit or other upgrade, we will explain why.

​

Do you work on both homes and business sites?

Yes. We work in homes, shops and other business sites across Inverclyde and North Ayrshire. Our work includes fault finding, repairs, rewiring, fuse box upgrades, sockets and lights. Each site has its own needs, so tell us what the space is used for and what you want done. We can then discuss the next step and arrange a quote.
