The Sunlight Process

On our first visit to your property, we will carry out a survey of your loft and other areas of your home to confirm the feasibility of the conversion. We will then discuss various designs with you to ascertain your exact requirements, enabling us to prepare a FREE comprehensive quotation and floor plan.

A Schedule of Payments document will also be given, in order to clarify the payment dates for your conversion. This allows us to show you that our pricing is completely transparent, and that no “hidden extras” exist. In addition, please note that a final payment will only be required once all work is completed and passed by an approved Building Inspector.

Once deciding to proceed, our Surveyor will carry out a full survey of your property and will produce detailed plans and calculations, which on approval by you, will be submitted to the relevant departments at your Local Authority. If planning permission is needed, it will normally take 8 to 12 weeks to be processed, depending on your Local Authority. Sunlight Lofts will liaise with the Council regarding the progress of your application.

Changes to planning laws in 2008 mean the majority of properties do not normally require planning permission, apart from flats and properties in conservation areas.

All loft conversions will require Building Regulations Approval. A set of detailed plans will be sent to the Local Authority Building Control. On approval of the plans and commencement of the conversion, a Building Control Surveyor will visit the site on various occasions to ensure that the conversion is carried out in accordance with the approved plans. On completion of the loft conversion, the Building Surveyor will make a final inspection. A Completion of Works certificate will then be issued by the Local Authority to complete the set of documents required. This completion certificate will be important for the future conveyance of your property when selling.
