Explain the part of the building you occupy
For a Forest Hill property, state whether you occupy the whole building or a flat within it. A shared front entrance and private accommodation need different permissions and responsibilities. The same applies to a business unit inside a larger premises. Tell us where the work should start and end.
Lewisham Council publishes a Forest Hill conservation-area map and related information. If a relevant designation applies to the address, check the restrictions before agreeing visible external equipment. This is an address-specific question, not a reason to assume every property has identical constraints.
Choose the outcome you want
For an alarm, explain when the space is occupied and which entrances are used. For CCTV, describe the view needed and why you want it recorded. For door entry, explain how visitors currently reach the right person. The local service pages develop those questions without requiring you to pick products first.
If existing equipment is difficult to operate, say what makes it inconvenient. A control arrangement that does not suit the occupants deserves discussion alongside technical condition. Where the property has changed layout or ownership, include those changes in the enquiry.
Plan the quotation around practical access
Mention limits on drilling, cabling or access through shared parts of the building. Include the timing of refurbishment and who can authorise the work. C&C can discuss an initial estimate or arrange a survey and provide a free quotation. Ask for retained equipment, new installation and optional ongoing services to be distinguished so the proposed arrangement is easy to understand before installation is booked.
