It is one reason we quote after the survey rather than over the phone. The point of a proper test is that the result is repeatable by anyone else with the same instrument. That is checked with instruments, not by eye. If you are weighing up at a Mountain Ash address, the useful detail is below rather than in a brochure.

What's different about Mountain Ash
The practical version — most Mountain Ash terraces need the charger fed from the main CU on a dedicated 32A circuit — fine for short runs, but anything over 10m of cable starts to push the price up because of cable size and clipping time.
Typically — the dense Penrhiwceiber terraces have shared party walls that affect cable routing for rewires and EV chargers, which often means a consumer unit upgrade is the smartest first step before a charger goes in.
Free DNO notification handled for you is the reason a phone quote would be a guess.
Fixed price written before any work starts — the sort of thing an inspection catches long before a fault does.

Common questions
Do you offer scheduled repeat visits?
Yes. Where an installation needs periodic checks we diary it rather than leaving you to remember.
Do you charge to come out and look?
Attendance and testing are quoted before we travel to Mountain Ash, so there is nothing added afterwards that was not agreed.
How do I know the price will not change?
Because it is set after testing, not before. Extra work is only ever agreed with you first.
Do you deal with the paperwork for the council?
Where notification is required, it is submitted to Rhondda Cynon Taf County Borough Council as part of the job.
Do you cover Mountain Ash for cost guide?
