Moving to Cardiff and need an electricians advice? Contact me to ask a question or see if it’s been answered below:

Q. I am experiencing some electrical problems in my flat on Cathedral Road and think i need an electricians help. I have woken up twice this week and power for the whole property is off. The rcd switch turns back on but there is obviously an underlying wiring problem. Any advice what i can check? How soon could you call out? I live at the Clare Street end near Sophia Gardens. Thanks Mike.

A. Hello Mike. You could take a look at my rcd tripping article – that may help. If not, i am working in Hamilton Street this week so could call in one evening to take a look. Thanks Simon

Q. I have recently moved in to an apartment in Altolusso and would like to replace all the light fittings. Do you supply and fit only?

A. You can purchase light fittings to suit your rooms decor and budget. Don’t be put off by sealed lights – that is something that cannot have the lamp removed. This is the way a lot of lights are being manufactured now. LED based fittings last a long time, cost less to run and generate no heat. I would recommend taking a look at the Astral lighting store on Sloper Road.

Q. Simon, I have an office in Charles Street, CF10 and have computer problems which we believe is due to faulty cabling. Is this something you would be able to resolve/quote to put right?

A. Yes, i install and troubleshoot problems with data cabling. Please respond with your full address and opening hours so i can arrange a convenient time to take a look at what is involved to resolve.

Q. I am looking for local electricians to provide costs to replace a distribution board that was damaged as a result of moving office furniture. My business is based in St Andrew’s Cresent. Is this something you would be interested tendering for?

A. Yes. Please can you provide your full contact details so i can arrange to call in to provide a cost and out of hours time to complete the works.

Q. I recently moved in to an apartment in Dumballs Road and assumed someone had turned the fuse off for the lighting because it was empty although now realised it switches off randomly! Can you offer any advice on what i can check, or do i need a call out? Thanks Karl

A. Hi Karl. If it is the circuit protection for the lighting tripping then you could remove the lamps from the fittings and replace one at a time to see if that helps. If not, look for a pattern – does it happen when a certain room is used for example? There are other electrical items connected to lighting circuits – such as extractor fans inside bathrooms which could be causing a problem. If you have one, it is worth turning the isolator off to rule that out. If all that fails, i am working in Overstone Court on Friday so could call in and take a look for you.

Q. I am looking at having a new kitchen installed and the first company i called in said all the electrics will need to be replaced. I live in relatively new apartments near St Davids Hospital and would like a second opinion/quote to carry out the work. Can you help?

A. Kitchens have the most electrical requirements within the home so i would need to see plans of what appliances you are contemplating having – and where before attending to price the proposed work. Thanks Simon

Q. My electric shower has started dribbling water out of the bottom of its case. We moved in to Corvette Court ten years ago and it was already installed so guess it needs replacing. There is an electrician living nearby who looked at it and said other work is required to get up to the latest standard. I am looking for estimates to carry out the work required to get a new, powerful shower installed.

A. I agree that a ten year old faulty shower should be replaced and not repaired. The additional work the electrician mentioned may include rcd protection and main bonding. Would you like me to call in tomorrow evening between 6 and 7 pm to take a look?

Q. Hi, I am looking at purchasing an apartment on Westgate Street in the City Centre and the building societys surveyor has suggested having the electrics tested. What is involved with this? The current owner is still living there.

A. Hi. Some of the testing requires the circuits to be de-energised. This means there will be periods with no power at all. I carried out an inspection on a two bedroom apartment in Westgate Steet last year and it took four hours – start to finish. Let me know if this is something you wish to book in. Thanks Simon.
