The campaign, which uses the strapline: “Making Christmas more Affordable”, launches on 6 November.
It includes television advertising and a direct mail drive including an eight-page leaflet distributed to three million people.
The retailer says the festive campaign is its “biggest ever marketing spend”.
BrightHouse is currently the sponsor of Australian soap Home and Away on Five since signing a 12-month deal with the broadcaster in June.
As part of the Christmas marketing campaign, BrightHouse will incorporate its “traditional warm red and gold” Christmas creative into its sponsorship idents.
BrightHouse operates 189 stores in the UK and allows customers to pay on a weekly basis, without paying a large deposit or being subject to credit rating checks.
The business has weathered the recession well, and has seen five successive years of growth.
Leo McKee, BrightHouse chief executive has said he would like to grow the chain to open 650 BrightHouse stores across the UK.
