How to Choose a Smart Home Installer in Sussex: 9 Questions to Ask Before You Book

A good smart home installer in Sussex will visit before quoting, put the price in writing, run cables for anything that matters (lights, heating, cameras) and hand over every password when the job is done. Ask the nine questions below before you book. The answers tell you more than any logo on a van, and the first one costs nothing.

The nine questions at a glance

Keep this open on your phone during the visit. The last column is the answer a good installer gives without being prompted.

#	Question	The answer you want to hear
1	Do you survey first and put the quote in writing?	"Yes. The survey is free and the quote is fixed and itemised."
2	Will you wire the things that matter, or is it all WiFi?	"Lights, heating and cameras go on cables; WiFi carries phones."
3	What happens if the cloud service behind this is switched off?	"It keeps working locally. We favour Matter, Zigbee and UniFi."
4	Who owns the passwords and the configuration afterwards?	"You do, with a written handover and a backup of the setup."
5	What is the warranty?	"In writing: 12 months on workmanship plus the manufacturer's warranty."
6	Are you insured?	"Yes. Here is the public liability certificate."
7	What happens after the job if something stops working?	"Call us. We also check in a few weeks after the install."
8	Can I see photos of a recent job?	"Yes, including the back of the cabinet and the cable routes."
9	Is there anything on my list I do not need?	"Probably. Here is what we would leave out and why."

Why each question matters

Survey and written quote

Smart home work is mostly wiring, positioning and configuration, and all three depend on the house. A quote over the phone or from a web form is a guess, and the shortfall shows up as extras on the day. A written, itemised quote lets you compare two installers like for like and holds the price. We survey free across Sussex and quote fixed.

Wire what matters

WiFi bulbs and plugs are quick to fit and quick to fail: they drop off when the router reboots, they clog the network, and when the broadband provider swaps the router they all need re-pairing. Lighting, heating, blinds and cameras should sit on cables, or on a low-power mesh (Zigbee or Thread) with a wired hub. Our smart lighting installation page explains how we wire lighting so the wall switch still works.

Cloud switch-offs and local control

Every few years a tech company switches something off: Works with Nest, assorted hubs, and this year Google Assistant itself. Kit that depends entirely on a cloud server stops when the server does. Ask whether the lights still switch, the heating still runs and the cameras still record if the internet is down or the brand folds. Matter devices, Zigbee on a local hub and UniFi networking all carry on.

Ownership, warranty, insurance and aftercare

At the end of a job you should hold the admin login for every system (WiFi controller, camera recorder, hub) plus a short document listing what was fitted and how to do the basics. Some installers keep the admin passwords so you have to call them, which is lock-in dressed up as support. A warranty that lives in a conversation is not a warranty either: ours is 12 months on workmanship and 2 years labour on CCTV, printed on the quote. Any installer working in your home should carry public liability insurance and send the certificate before the job. For aftercare, ask what happens when a device stops responding six months on, then read their reviews looking for "came back" rather than "lovely chap".

Photos, and the things you do not need

The front of a smart home looks the same whoever fitted it. The difference is behind the panel: a labelled patch panel and tidy cable runs, or a bird's nest the next engineer has to rip out. Ask for photos of a recent job's cabinet. A good installer will also cross things off your list; if nobody tells you the smart kettle is a waste of money, they are selling to you, not advising you.

What smart home work costs in Sussex

Figures at the time of writing, fitted and configured, to size your expectations before the survey:

• A first smart lighting room or two: from a few hundred pounds, with wired switches that still work by hand.
• Whole-house lighting control: the low thousands, depending on the number of circuits and how much rewiring the house needs.
• Mesh WiFi, fitted and tuned: £300 to £800, the foundation everything else depends on.
• 4-camera CCTV system: from about £1,100 installed.
• A full "goodnight button" integration: lighting, heating, blinds, cameras and audio working together, £3,000 to £10,000 depending on the house.

Two installers quoting the same house on the same kit should land within a few hundred pounds of each other; a quote far below the others has left something out, usually cabling or configuration time. Our whole-home integration guide explains what the top of that range buys, and the smart home beginners guide covers what to buy first.

Red flags

• A quote without a visit. See question one.
• "Unlimited" anything. Unlimited devices, unlimited support, unlimited range. Physics and payroll say otherwise.
• A national call centre. The salesperson never sees your house; the fitter is a subcontractor paid by the hour.
• Pressure to sign on the day. "This price is only valid today" is a sales technique.
• Subscription-only kit. If the lights stop when you stop paying, you are renting your own house.

Why Sussex houses need a visit

Sussex housing stock is unusually varied, hence question one. A brick and flint cottage in the Downs villages has walls that stop WiFi dead and no voids for cables, so lighting goes on a Zigbee mesh and the access points sit in the rooms. A 1930s semi in Horsham or Crawley has a loft you can crawl and a consumer unit under the stairs, so wired lighting and a ceiling access point are straightforward. A Brighton terrace is tall and narrow, so one access point per floor beats one big router. A new build in Burgess Hill has foil-backed plasterboard that reflects WiFi, but neat voids and sometimes a data cabinet in the cupboard. None of this shows on a form.
