Questions people ask first

How quickly can someone come?

Within working hours we usually confirm a technician the same day on the electrical line.

Will I know the price before the work starts?

The technician inspects, then quotes from the price book before touching anything.

Can I buy the materials myself?

You can, and then you pay labour only.

Why should I not just take the technician's number?

Because then nobody is accountable — no job number, report, warranty, invoice or complaint route.

Do you work on Friday and at night?

Yes, by arrangement, with labour at plus 50 per cent outside normal hours.

What happens if a technician damages something?

Report it to the office with the job number; the photographs settle what was already broken.

Do you issue a VAT invoice for company accounts?

Yes, invoiced from THB with VAT shown on its own line.
