Smart home installation costs in the UK vary enormously — from £0 if you’re happy doing it yourself, to £5,000+ for a professionally installed, fully integrated system. Most households land somewhere in the £200–£2,000 range, depending on how many systems they’re automating and whether they bring in a professional.
This guide breaks down the real costs — products, installation labour, and ongoing subscriptions — so you can budget accurately before you start.

DIY installation is genuinely achievable for most smart home devices. Smart plugs, smart bulbs, thermostats (most models), video doorbells, and wireless cameras are all designed for homeowner installation with a screwdriver and a smartphone. The savings are significant: a Hive thermostat installed by you costs around £109 for the device; installed professionally by British Gas it’s £249–£299 including lSmart Radiator Valves UK 2026: Tado vs Meross vs EveBest Smart Thermostats UK 2026How to Set Up Smart Home on Budget 2026 UKabour.
Professional installation makes sense when you need electrical work (smart light switches require rewiring), structured cabling (Ethernet runs for wired cameras), or a system complex enough that getting it wrong is expensive. An electrician installing smart lighting throughout a 4-bedroom house is safer and often faster than a DIY attempt by someone who hasn’t done it before.
The hybrid approach (most popular): buy devices yourself online to save on hardware, then hire an electrician for the electrical bits only. You get near-DIY prices with professional safety on the wiring.
Smart Lighting Costs UK
Smart Bulbs (DIY — No Electrician Needed)
Smart bulbs are the cheapest way to get smart lighting. They screw into existing fixtures — no wiring changes required.
| Bulb Type | Cost Per Bulb | Cost Per Room (est. 3 bulbs) | Hub Required? |
|---|---|---|---|
| TP-Link Tapo L530E (Colour) | £10.99 | ~£33 | No (WiFi direct) |
| Wiz Connected (Colour) | £12.99 | ~£39 | No (WiFi direct) |
| Philips Hue White | £14.99 | ~£45 + £49.99 Bridge | Yes (Hue Bridge) |
| Philips Hue White & Colour | £34.99 | ~£105 + £49.99 Bridge | Yes (Hue Bridge) |
| LIFX A60 (Colour) | £29.99 | ~£90 | No (WiFi direct) |
For a typical 3-bedroom house (living room, 3 bedrooms, kitchen, hallway = 6 rooms, ~3 bulbs each), expect to spend £200–£650 on bulbs depending on brand, plus a one-off hub cost if you go Philips Hue.
See our smart light bulbs comparison to pick the right brand for your home.
Smart Light Switches (Professional Installation Recommended)
Smart switches replace your existing wall switches and require a neutral wire in most cases. If your house was built before 1995, you may not have neutral wires at your switches — an electrician will need to check before you buy.
| Product | Switch Cost | Electrician Labour (per switch) | Total per Switch |
|---|---|---|---|
| Tapo S220 Smart Switch | £19.99 | £40–£60 | ~£60–£80 |
| Hive Active Light (switch) | £29.99 | £40–£60 | ~£70–£90 |
| Lutron Caseta (requires bridge) | £54.99 + £79.99 bridge | £40–£60 | ~£175 first switch |
A 10-switch installation (covering main living areas) typically costs £700–£1,200 all-in for mid-range switches including labour. Electrician call-out rates in 2026 average £50–£80/hour in the UK; most switch installations take 20–30 minutes each once the electrician is on-site.
Smart Heating Costs UK
Smart thermostats are among the best-value smart home investments — they typically save 10–25% on heating bills, which at current UK energy prices means £100–£300/year savings for an average home.
| Product | Device Cost | Professional Install | DIY? |
|---|---|---|---|
| Tado Smart Thermostat V3+ | £109.99 | £80–£120 (plumber/electrician) | Yes (most systems) |
| Google Nest Thermostat | £119.99 | £80–£120 | Yes (most systems) |
| Hive Active Heating | £179 (device only) | Included in British Gas install (£249 total) | Possible but not recommended |
| Honeywell Home T6 | £79.99 | £80–£120 | Yes |
Smart radiator valves (TRVs) are an addition to a smart thermostat — they let you control individual room temperatures. The Tado Smart Radiator Thermostat V3+ costs £69.99 per valve and is DIY-installable in most cases (unscrew the old TRV, screw on the Tado). A full 10-radiator installation costs £700–£900 in devices alone. Our best smart thermostats guide covers Nest vs Tado vs Hive in detail.
Smart Security System Costs UK
DIY Wireless Alarm Systems
| Product | Starter Kit Cost | What’s Included | Monthly Fee |
|---|---|---|---|
| Ring Alarm 5-piece | £199.99 | Base station, keypad, contact sensor, motion sensor, range extender | Optional (£8/month for monitoring) |
| Yale Smart Living IA-320 | £249.99 | Alarm, PIR sensor, door contacts, siren | None required |
| Abode iota All-in-One | £199.99 | Hub/siren/keypad combo, door sensor, motion sensor | Optional (£8/month pro monitoring) |
| SimpliSafe Essentials | £169.99 | Base station, keypad, entry sensor, motion sensor | £9.99/month for monitoring |
DIY wireless alarm installation takes 30–90 minutes. No electrician needed — everything is battery-powered and connects via WiFi or a proprietary radio frequency.
Professionally Monitored/Installed CCTV
For a fully installed, hardwired CCTV system with an NVR and professional installation, budget:
- 4-camera wired system (Hikvision/Dahua quality): £600–£1,200 installed
- 8-camera system: £1,200–£2,500 installed
- Installation labour only (electrician/CCTV installer): £200–£400 for a 4-camera install including cable runs
- Ongoing monitoring contract: £15–£40/month depending on response level
For outdoor cameras specifically, see our full review of the best home security cameras UK — which covers both DIY wireless and hardwired options.
Full Smart Home Package Costs UK
| Package Level | What’s Included | Typical Cost (3-bed house) |
|---|---|---|
| Basic DIY | Smart bulbs throughout, 2-3 smart plugs, smart thermostat (DIY install), video doorbell | £400–£700 |
| Mid-Range DIY+ | Above + wireless alarm system, 2 outdoor cameras, smart door lock, smart TRVs on 5 radiators | £1,200–£2,000 |

| Premium Full-Home | Full Lutron/Control4 lighting, access control, AV integration, professional commissioning | £10,000–£30,000+ |
Most households reading this guide are in the Basic DIY to Mid-Range DIY+ bracket. Our smart home on a budget guide covers how to prioritise spending when you’re working with a limited budget.
Electrician Costs and Checkatrade Averages
When professional installation is needed, the labour cost is often the biggest variable. Here are realistic 2026 UK rates:
- Electrician call-out/first hour: £50–£100 (higher in London and South East)
- Half-day rate (4 hours): £180–£320
- Full-day rate (8 hours): £300–£550
According to Checkatrade’s 2025/2026 data, the average cost for an electrician in the UK is around £55/hour outside London, rising to £75-£90/hour in Greater London. Always get three quotes for any job over £300.
Checkatrade and NearbyTraders are the two most reliable platforms for finding vetted tradespeople in the UK. NearbyTraders is particularly useful for smart home installers and electricians who specialise in home automation — you can filter by specialism and see verified reviews. For straightforward electrical jobs (switch installation, camera cable runs), Checkatrade’s quote tool is a good starting point.
Hidden Costs to Budget For
Subscriptions: Many smart home devices have optional or required cloud subscriptions. Ring Protect: £3.49–£10/month. Arlo Secure: £4.99/camera/month. SimpliSafe monitoring: £9.99/month. Budget these before buying — they add up to £200–£600/year for a full system.
Routers and network upgrades: A house-full of smart devices needs a solid WiFi network. If your router is old or you have dead spots, add £60–£150 for a mesh WiFi extender (TP-Link Deco or Amazon Eero) before the smart home devices fail to connect properly.
Smart home hubs: Some ecosystems need a hub (Philips Hue Bridge: £49.99, Amazon Echo as a hub: £54.99). Factor this in when comparing “cheaper” devices that actually need hub hardware to function.
Cabling for wired systems: If a CCTV installer is running CAT6 or coax cable through walls and lofts, materials typically add £50–£150 to the job depending on cable lengths.
How to Get Quotes for Smart Home Installation
For any professional smart home installation job in the UK:
- Use NearbyTraders or Checkatrade to find verified local electricians and smart home installers
- Get at least three quotes — prices vary significantly by area and installer experience
- Specify whether you’re supplying your own devices or want the installer to supply and fit
- Ask whether the installer is NICEIC or NAPIT registered for any electrical work — this protects you if work needs to be inspected later
- For multi-room systems, ask if the installer offers a commissioning service (setting everything up in the app, creating automations) — some smart home specialists include this, others charge extra
Frequently Asked Questions
Do I need an electrician to install smart home devices?
Not for most smart home devices — smart bulbs, plugs, thermostats, cameras, and alarm systems are all designed for DIY installation. You do need a qualified electrician if you’re installing smart light switches (which require rewiring at the switch plate), running new cable, or doing anything that touches your consumer unit (fuse box).
How much does it cost to make a 3-bedroom house fully smart?
A genuinely useful DIY smart home for a 3-bed house — smart lighting throughout, smart heating, video doorbell, two outdoor cameras, and a wireless alarm — typically costs £1,500–£2,500 in hardware if you’re installing yourself. A professionally installed equivalent would run £4,000–£7,000 including labour for the electrical work.
Does a smart home add value to a property?
Smart home features can add perceived value and help sell a property faster, but estate agents disagree on hard valuation uplift. Permanent, professionally installed systems (integrated lighting control, built-in CCTV, smart heating) are more likely to add value than plug-in devices a seller takes when they move. A 2024 Halifax survey found 36% of UK buyers would pay more for a home with smart home features already installed.
What’s the cheapest way to start building a smart home?
A smart plug (£9–£14) and a smart bulb (£7–£11) is genuinely all you need to start. Total outlay under £25, works with Alexa and Google Home, and gives you an instant taste of automated lighting and appliance control. Start there, see if you actually use it, then expand. Most people are surprised how much they use a £14 smart plug before they buy anything else.
Are professional smart home installers worth the cost?
For complex, whole-home systems — yes. A good smart home integrator will design a system that actually works together, rather than a collection of apps that sort of talk to each other. For standard installations (bulbs, plugs, thermostat, doorbell), DIY is absolutely fine and saves hundreds. The £500–£1,000 professional premium only makes sense when there’s real electrical work involved or when you’re spending £5,000+ on hardware and want it done properly.
Our Verdict
Smart home installation costs in the UK can be as low as £25 or as high as £30,000 — the question is what you actually want. For most homeowners, a realistic DIY budget of £500–£1,500 covers smart lighting in the main rooms, a smart thermostat, video doorbell, and either a wireless alarm or two outdoor cameras. That’s a meaningfully smarter home for less than a week’s family holiday.
Where professional installation earns its keep is in electrical work — smart switches, wired CCTV, and anything that goes near your consumer unit. For everything else, the devices are designed to be installed by the homeowner, and the savings are significant. Use NearbyTraders to find trusted local tradespeople if you do need professional help.
