In an older house, access to concealed wiring needs thought before finishes are disturbed. A route beneath a timber floor may involve different preparation from one behind fitted furniture or through a previously altered wall.
We discuss the proposed access points and the features you want to preserve. Floor protection, opening up, plaster repairs and final decoration should have clear responsibilities, with any exclusions recorded in the quotation.
For flat rewiring in Hampstead, the survey also considers the individual dwelling's supply and the parts of the installation that serve it. Access to communal cupboards or routes through shared spaces may need to be arranged with the freeholder or managing agent.
Tell us about any listed status or existing conservation advice when you enquire. Where proposed work could affect protected features, the relevant advice and any required consent should be established before installation begins. Requirements depend on the building and the alterations involved.
