Separate your front door from shared access
For an Abbey Wood flat, explain where your own accommodation starts. A communal front door and the door to your flat are separate points of entry, and responsibility for them may sit with different people. Tell us whether you want an alarm for your private rooms or are enquiring on behalf of the whole building. That prevents a quotation being based on the wrong boundary.
For a house, describe all the ways you normally enter, including a rear door used more often than the front. The place you set the alarm should work with that route, not force an awkward detour through the property.
Decide what stays occupied
If someone remains upstairs while other rooms are unused, discuss how that should work before choosing detectors. Explain pets, overnight routines and any room used as a home office. These are requirements to assess, not reasons to assume a particular detector or wireless package will fit.
When moving into a property with an existing alarm, gather any paperwork and the equipment model if available. Do not assume a system is ready for a new household simply because a keypad lights up. Ask about its condition, user access and the suitability of its present coverage.
Agree the response as well as the equipment
Consider who could respond when you are away from Abbey Wood. A phone notification is useful only if someone can receive and act on it. Ask separately about monitoring, maintenance and associated charges. The quotation should distinguish those services from the installation itself. At handover, have the people who will operate the alarm practise the agreed setting and unsetting routine with the engineer.
