Why the visit comes before the proposal
Automation is decided by the building far more than by the brochure. A lighting scene that is straightforward in one villa needs a new circuit in the next. A curtain that motorises without fuss in one apartment meets a pelmet too shallow for a motor in another. Until somebody has looked, a proposal is a set of assumptions with a price attached, and assumptions surface later as extra work or as scope that quietly disappears.
So a survey has one job: to replace guesses with observation. It helps if whoever walks round knows the property, meaning where the boards are, which rooms actually get used, and what has been changed since handover. Access matters too, because the locked store room is usually the one with something worth seeing in it.
The distribution board
The board is the first stop, because it sets the boundaries for everything else. What can be controlled, how finely, and where equipment can live are all questions it answers before a single product is discussed.
- How many boards there are and where they sit. A villa often has more than one, perhaps a board per floor plus a separate one for the annexe, garden or pool plant.
- How many spare ways are free, and whether the board is physically full. Controlled circuits need somewhere to land.
- How the circuits are divided. Whether a floor of lighting is one circuit or six changes what scene control can do, because a scene only acts on circuits that already exist separately.
- Whether the labelling is accurate, which gets checked by switching, not by reading. Boards are commonly labelled from the original drawing and altered afterwards.
- Whether there is space, ventilation and a sensible cable route near the board for control equipment, or whether it belongs somewhere else entirely.
Behind a switch plate
Retrofit lighting control usually lives in the back box behind an existing switch, so a survey involves taking at least one plate off, with the circuit isolated and with your agreement. It's the most informative moment of the visit, and what one room shows usually says a lot about the rest.
- Whether a neutral conductor is present in the box. Plenty of older switch drops carry only the live and the switched line, and a module that needs a neutral can't go where there isn't one.
- How much depth sits behind the plate. A module has to fit alongside the existing conductors, and a shallow box set into blockwork can rule that position out.
- How many gangs the plate has and how many circuits land in the box, which decides how many channels of control the position can carry.
- Whether a light is switched from more than one place, since two way and intermediate switching change the approach for that circuit.
- What the wall is made of, because concrete and blockwork behave differently from a plasterboard partition, both for fixing and for radio.
- Where a keypad would ideally sit for the way the room is used, and whether that position has any wiring behind it at all.
Ceilings, voids and cable routes
Once the walls are closed, the ceiling is usually the only remaining path between rooms. How much of one there is decides whether a cable can be added quietly or whether the honest answer for that room is wireless.
- Whether the ceiling is a solid slab or a suspended gypsum ceiling, and if suspended, how much void sits above it.
- Where access panels already exist, and where one could be formed without cutting into a decorative feature.
- How the existing downlights are laid out and where their drivers sit, since that is often the easiest point at which to reach a lighting circuit.
- Whether cove details, bulkheads and pelmets are hollow. A hollow detail is a ready made route; a solid one is not.
- Where risers and containment run between floors, and whether spare capacity is left in them.
- In an apartment, which parts of the ceiling, riser and facade belong to the building and not to you.
Curtain tracks, pelmets and fixings
Motorising curtains is mostly a question of what the window opening will physically accept, so this part of the survey happens with a tape measure. Existing fabric is often reusable; it is the track and the space around it that decide. Blinds raise the same questions in a different form, with the recess depth and the barrel taking the place of the pelmet and the track, and our page on motorised curtains and blinds sets out what each type needs.
- Pelmet depth, and the clear space above and behind the track, because a motor and tube need room while the fabric still has to hang straight.
- Side clearance at one end of the track for a motor head, and which end has, or could have, power.
- Whether the track is straight, curved or follows a bay, and whether the window is one run or several.
- What the track and pelmet are fixed into. A track carrying heavy blackout fabric plus a motor needs a fixing suited to concrete, blockwork or gypsum, and fixings into gypsum alone get looked at closely.
- Whether sheer and blackout layers share one double track or run separately, since every layer that moves on its own is another motor.
- The drop, the width and the weight of the fabric, all of which affect motor selection.
Air conditioning, room by room
Cooling is where automation has the most to work with in this climate, and it is the system where the survey matters most, because control depends entirely on what is already fitted and how it is wired. Nothing about a room's furniture or finish changes this part, which is why our air conditioning control work starts at the controller and the plant behind it.
- What serves each room: a wall mounted split, a ducted unit covering several rooms, or a fan coil unit fed with chilled water from a central or district cooling plant.
- Where the control point physically sits, and whether one controller serves one room or several.
- What wiring is behind that controller. Taking the faceplate off, with the unit isolated, shows what the existing thermostat actually switches, and that decides which control approach fits.
- How the fan speeds and any water valve are operated, because a fan coil is controlled differently from a split.
- Whether the controller can read the room honestly, or whether it sits above a lamp, beside a door or in the draught from a supply grille.
- Whether a ducted system already has zone dampers, and where the damper motors and their control sit.
The network and where equipment lives
Every automated property has a small amount of equipment that needs somewhere to live with power, air and a route to the outside world, and finding that place is a survey task. Coverage gets sanity checked by walking the property with a device in hand, but a walk is a check, not a design, and the network design that follows is drawn from the building itself.
- Where the incoming internet service terminates and where the router sits today. In many apartments that is a shallow cupboard by the entrance with a metal door, which is a poor home for anything wireless.
- Whether that position has a spare socket, room for more equipment and any airflow, since a cupboard that runs warm shortens the life of whatever is inside it.
- Whether data outlets already exist, and whether they terminate anywhere useful or simply disappear into a wall.
- Where access points would need to go for the layout of the property, and how a cable would reach each position.
- How the building is built between floors, because a concrete slab is a far bigger obstacle to radio than a timber one.
- Where cameras, door stations and other cabled devices would come back to, since they all end up in the same cupboard.
Outside: gate, entry and cameras
External work has its own checklist, and it is the part most often left until the proposal stage, which is exactly when the awkward details appear.
Cameras carry an additional consideration here. Security camera work in Dubai is regulated by SIRA (opens in a new tab), what applies depends on the property and its use, and the authority itself is where current requirements should be confirmed. A survey is the right moment to raise it, before positions are agreed, and our guide to CCTV rules in Dubai sets out the context.
- Whether a gate operator is already fitted, what type it is, and whether the gate runs freely. Automation can't rescue a gate that drags, so the leaf, track, rollers and hinges are all part of the check.
- Whether there is a power supply at the gate and where it comes from. Where none exists, the route from the house is measured, because that cable has to cross the driveway or follow the boundary.
- The distance and route from the house to the gate and the pedestrian door, since intercom, camera and control cabling all follow the same path.
- The existing door station and doorbell wiring, and whether it can carry a video intercom or has to be replaced.
- Camera positions, what each one would genuinely see, and whether a position sits in full sun for most of the day.
- External sockets, garden lighting, irrigation control and pool plant, plus anything fixed to a facade, boundary wall or shared area, where community rules and building management approval come into play.
The questions that are not about the building
Half of a survey is a conversation, because the same house automated for two different households ends up as two different systems.
- Who lives there, how many people and their ages. A home with small children and a home with elderly parents want different automatic behaviour after midnight.
- Who has to operate it without being shown twice: a guest, a housekeeper, a family member with no interest in an app.
- What already annoys you. A list of small daily frustrations is more useful than a list of features, because it points at what the system has to fix to be worth having.
- Whether you own or rent, and if you rent, what the lease and the building allow, because that decides how much of the specification has to be removable.
What a survey cannot settle, and what follows it
An honest survey ends with a short list of unknowns. What sits behind every plate is inferred from the one or two that were opened. How radio behaves once a home is furnished and occupied changes with people, glass and metal. What building management will permit in a tower belongs to the building and has to be asked formally. Anything above a solid ceiling stays unknown until it is opened.
A proposal written from a good survey states those openly, says what will be confirmed at first fix, and describes what happens if something behind a wall turns out differently. A proposal that reads as though everything is already known is the one that produces surprises.
The record from the visit then becomes the basis of a design: which circuits get controlled, where equipment lives, what runs wireless and what needs cable. A good survey usually narrows a project and produces an order of work, so anything requiring cable happens while walls are open. If the property is still under construction, the timing question changes shape entirely, and our guide to new build and retrofit covers that decision.
In short
A site survey is the point where automation stops being a category and starts being your property. The checklist is unglamorous, distribution boards, back boxes, ceiling voids, pelmet depths, thermostat wiring, router positions and gate power, but it is the difference between a proposal that describes your building and one that describes a typical building. Expect the visit to be spent looking more than presenting, expect at least one switch plate to come off, and expect as many questions about your household as about your house. If you are being quoted without any of that, you're being quoted on assumptions.
Common questions
It's a building inspection. The visit covers the distribution board and its spare ways, what sits behind a switch plate, whether ceilings are solid or suspended, the depth of curtain pelmets and what the tracks are fixed into, the type of air conditioning in each room and the wiring behind its controller, where the router and any equipment can live, and outside, gate power, entry cabling and camera positions. Alongside that come questions about who lives in the property and how it is used, because that is what decides how the system should behave on its own.
Access is the main thing: unlocked rooms, the store cupboard, the roof or plant area if there is one, and clear space around the distribution board. It helps to have someone present who knows the property, particularly if anything has been altered since handover. If you rent, keep your lease terms to hand, and in an apartment it is worth knowing whether the building requires notice before any work. A floor plan is a bonus and not a requirement, since the survey records the building as it stands.
Nothing is installed and nothing needs drilling. With your agreement, a switch plate or two comes off with the circuit isolated, the cover of the distribution board is opened to see the ways and how the circuits are arranged, the faceplate of an air conditioning controller may be removed with the unit isolated, and a ceiling access panel is lifted where one already exists. Everything goes back as it was. If you would prefer nothing was opened, say so, and the survey works from what can be seen without it.
Photographs help and are worth sending in advance: the open distribution board, the front of each air conditioning controller, the switch plates in the main rooms, the curtain pelmets, and where the router sits. They narrow the options and sometimes rule an approach out early. What a photograph cannot show is what sits behind a plate, how deep a back box is, whether a neutral is present, how radio moves through the building, or the mechanical state of a gate. A quote built only on photographs carries assumptions, and those assumptions belong in the quote in writing.
The checklist is the same but the constraints differ. An apartment usually has one distribution board with less capacity to spare, ceilings and facades that belong to the building, air conditioning that is often a fan coil unit fed from a central or district cooling plant, and a management office whose permission is needed before anything is fixed to a shared surface. A villa gives more to inspect: more than one board, external runs, gate and garden circuits, and radio that has to cross thicker walls and more floors.
Then it is a drawings exercise as much as a site walk. What matters at that stage is containment and cable routes, space and ventilation for a panel and rack, power brought to curtain pelmets, positions for keypads and access points, and the paths from the gate and boundary back to the house. All of that is close to free while the walls are open and expensive once they close, so the useful conversation is about provision, not product. Product decisions can wait; pathways through the structure cannot.
