Hertfordshire & North London · Electrical work in Buckinghamshire
Practical people.
Clear advice.
Careful workmanship.
TNG Services brings the trades that keep a property running together in one team.
A heating fault can involve controls and wiring. A kitchen installation can involve water supplies, waste pipework and electrical connections. We look at how those parts work together, so the job is considered as a whole.
Our work ranges from finding and repairing faults to servicing boilers, improving heating systems and installing new equipment. We explain what we find, discuss the appropriate options and agree the next steps with you.
