CASE STUDY

Domestic Re-Wire 4 Bedroom house, Lakenheath

Built in the early 70's this property in Lakenheath was bought by Mr. & Mrs. W as a let investment.  Initial contact regarded adding 240v mains to the first floor where only 110v existed and improving lighting on the ground floor.

A thorough Periodic Inspection found several potentially dangerous issues which we addressed as a matter of course.  These included mis-labelling of a switched live, overloaded fuse board and rodent damage to electrical cable in loft space.

Consultation with our client helped identify the best ways to make improvements to the property which included zoned low voltage, dimmable lighting in living spaces, addition of new light switches in key areas to improve convenience, the addition of safety circuits on a new consumer unit, external security lighting with motion and light sensors and increasing the number of mains sockets.  While new cable was being pulled through Cat 5e drops with termination points were added to each room for the property's own LAN.  Mains smoke and fire alarms were also added to each floor.

Project details were finalised, a timeline of works agreed and work undertaken within a matter of days, completing to agreed deadline.
