Purchase 4 Bedroom house which has been rewired but ugly surface mounted 'trunking' has been used.

We will require probably mid march an electrician to do the following.

Chased in existing wiring and possibly replace new consumer unit? We maybe able to supply materials and finishings for the job, this can be discussed. Must be able to cert p work. House will not be occupied so no messing about moving carpets/furniture or worrying about mess as the house is being redeveloped.
