Smart Home Electrical Upgrades Worth Considering in Andover

Published September 2026 | Smart Home Electrical Upgrades

In the First 10 Minutes

Smart home upgrades can feel overwhelming when you're not sure where to start. The good news is you don't need to overhaul everything at once. In the first few minutes of thinking about this, do a simple walk-around of your home.

Look at three things:

1. Your current lighting. Are you still running halogen spotlights or older incandescent bulbs? Count roughly how many circuits you have and how many light fittings per room. This helps you work out whether a smart bulb system or smart switch system makes more sense for your setup.
2. Your heating controls. If you've got a basic programmer on your boiler and a single room thermostat, that's a very common source of wasted energy. Note where the thermostat is located - if it's in a hallway, it's almost certainly giving you inaccurate readings for the rooms you actually live in.
3. Your consumer unit. Older properties in Andover, particularly those built before the 1990s, sometimes have consumer units that aren't compatible with modern smart devices or lack the spare capacity for new circuits. A quick photo of your consumer unit is useful. Note whether it has a wooden back board, which is a sign it needs replacing.

This walk-around isn't technical. You're just taking stock of what's there. Write it down on your phone. You'll need this information when you speak to an electrician.

Within the First Hour

Once you've done your walk-around, it's time to get a clearer picture of which upgrades would actually benefit your home. The most impactful smart electrical upgrades for most Andover homes fall into four main categories.

Smart Lighting
Smart lighting systems let you control your lights by voice, app or schedule. They also dim automatically, which cuts energy use in a way that fixed-output bulbs simply can't match. Brands like Philips Hue offer bulb-based systems that don't need any rewiring. If you prefer smart switches - which give a cleaner look and work with any bulb - that requires an electrician, because you'll typically need a neutral wire at each switch position. Many older Hampshire properties don't have this, so check before you buy anything.

Smart Thermostats
A smart thermostat like the Nest Learning Thermostat or a Hive Active Heating system learns your routine and adjusts heating accordingly. Installation typically costs between 100 and 200 pounds including the device. Most systems need a competent electrician or a Gas Safe registered engineer to fit, depending on how your boiler system is wired.

Smart Sockets and Energy Monitoring
Smart sockets let you remotely control any plug-in appliance and monitor its energy draw individually. A clip-on smart energy monitor that connects to your consumer unit gives you real-time data on your whole home's electricity consumption. These typically cost between 50 and 150 pounds for the monitor itself and are a sensible first step before committing to larger upgrades.

EV Charging Points
If you drive an electric vehicle, or plan to, a dedicated home EV charger is one of the most practical electrical upgrades you can make. A 7kW wallbox charger typically costs between 800 and 1,200 pounds installed, including labour. Only OZEV-authorised installers can carry out this work legally in the UK, so make sure you check credentials before hiring anyone.

If you're not sure which upgrades suit your property best, the Voltrade GoFIX diagnostic tool can help you identify where you're likely to get the best return before you commit to spending anything.

Same Day

Once you've identified what you want, get a qualified electrician involved early - not after you've already ordered equipment. A good electrician will tell you whether your consumer unit needs upgrading before anything else is touched, whether your existing wiring can support smart switches, and whether any of the work needs to be notified to Building Control under Part P of the Building Regulations.

Before you call, prepare the following:

• A rough list of the upgrades you're interested in
• The age of your property and whether it's been rewired in the last 25 years, if you know
• A photo of your consumer unit
• Any smart devices you've already purchased but not yet installed

When you call, ask specifically whether the electrician is experienced with smart home installations. Most qualified electricians working around Andover can fit smart thermostats and EV chargers without any issue, but experience with more complex systems - whole-home automation, multi-room audio wiring, or structured data cabling - varies considerably.

In Hampshire, Building Regulations Part P applies to electrical work in dwellings. Certain jobs must be either carried out by a registered competent person or notified to your local council. EV charger installations, consumer unit replacements, and work in kitchens or bathrooms all fall into this category. A reputable electrician will handle this notification for you automatically, and you should receive a completion certificate when the job is done.

The Installation Visit

What happens during an installation visit depends on the scope of work. Our engineers typically follow a consistent approach - isolate, inspect, install, test. Here's what to expect for the most common jobs.

Smart thermostat installation
This typically takes one to two hours. Your electrician will isolate the relevant circuits, remove the old thermostat and programmer, fit the new device, connect it to your boiler wiring, and walk you through the app setup. Expect to pay between 80 and 150 pounds for labour on top of the device cost, depending on how complex your boiler wiring is.

Smart lighting and switch installation
Fitting smart switches throughout a typical three-bedroom property in Andover commonly takes a full day. The electrician will check each switch position for a neutral wire, fit the smart switches or dimmers, and test each circuit individually before leaving. If neutral wires aren't present and need to be run, this adds both time and cost. Labour for this type of work typically runs at 40 to 60 pounds per hour.

EV charger installation
This is usually a half-day job. The electrician will assess your consumer unit's available capacity, install a dedicated circuit running from the consumer unit to the charger location (commonly a garage or driveway), mount the wallbox, and test the complete installation. You'll receive an Electrical Installation Certificate and the work will be registered with the relevant authority.

Consumer unit upgrade
If your consumer unit is old - particularly if it has a wooden back board or lacks RCD protection - your electrician will likely recommend upgrading it before adding smart devices. A consumer unit upgrade typically costs between 400 and 700 pounds including labour and takes around four to six hours, during which your electricity supply will need to be off. It's often worth combining this with other planned upgrade work to keep disruption to a single day.

The Following Week

The week after installation is when the upgrades start earning their keep - but only if you take a little time to configure things properly rather than leaving them on default settings.

For a smart thermostat, spend 10 minutes setting your schedule manually during the first few days rather than relying entirely on the learning mode. You'll get accurate results faster. Set target temperatures for different times of day and make sure the "away" mode activates whenever the house is empty.

For smart lighting, spend around 20 minutes grouping your lights into rooms and scenes within the app. A morning scene that gradually brightens kitchen and hallway lights, and an evening scene that dims the living room at a set time, are both practical and save energy without requiring any thought after initial setup.

Check your energy monitoring data at the end of the first week. It's common for homeowners across Hampshire to discover one or two appliances drawing significantly more power than expected - an ageing chest freezer in the garage, or a television left on standby constantly. Addressing these secondary issues can compound the savings from your smart upgrades considerably.

Also test each smart device from outside your home Wi-Fi network before the week is out. This confirms that remote access is working correctly, which matters most if you've installed heating controls or EV charging you'll want to manage while away from home.

Long Term

Smart home electrical upgrades are rarely a one-time event. Most homeowners who start with a thermostat and some smart lighting add to their setup gradually as they see results. Here's how to build on your initial investment without wasting money or creating problems for future work.

Expand your lighting system one room at a time
Rather than fitting smart switches throughout the whole house in a single pass, add them room by room as you redecorate or replace light fittings. This spreads the cost sensibly and means you're never paying to upgrade wiring you'd be touching again soon anyway.

Consider solar and battery storage
If you've installed EV charging or have above-average electricity use, solar panels combined with a home battery system - such as GivEnergy or Tesla Powerwall - can significantly reduce your bills over time. These installations require specialist electrical work and typically cost between 6,000 and 12,000 pounds, but payback periods are improving as energy prices remain improved. A good installer will model your usage patterns before recommending a system size.

Schedule regular electrical inspections
The standard recommendation for an Electrical Installation Condition Report (EICR) is every 10 years for an owner-occupied property. If you're regularly adding smart devices and new circuits, it's sensible to have your system inspected every five years instead. This ensures your consumer unit is coping with the added load and that all your installations remain compliant.

Keep firmware and software current
Smart devices rely on app and firmware updates for both performance and security. Set a monthly reminder to check that all devices are running the latest software. Outdated firmware is a real security vulnerability for anything connected to your home network.

Timeline Questions

How long does a smart home electrical upgrade take in Andover?

It depends on what you're installing. A single smart thermostat typically takes one to two hours. Smart switches fitted throughout a three-bedroom property commonly take a full day. An EV charger is usually a half-day job. If you're combining multiple upgrades - which often works out cheaper per job overall - allow one to two full days for a typical Andover home.

Do I need a qualified electrician for smart home upgrades or can I do them myself?

Some upgrades, like plug-in smart sockets or smart bulbs, don't require an electrician and can be set up by any competent adult. But anything involving work inside your consumer unit, installing new circuits, or wiring smart switches into walls requires a qualified electrician. In the UK, certain types of electrical work are also notifiable under Part P of the Building Regulations, and only a registered competent person can self-certify that work. Attempting notifiable work yourself can create problems when you sell the property.

Will smart home electrical upgrades add value to my Hampshire property?

Smart thermostats and EV chargers are increasingly cited by estate agents as adding real appeal to Hampshire properties, particularly in commuter areas where buyers are likely to own electric vehicles. A properly installed and certificated EV charger is increasingly treated as a standard feature rather than a bonus. Smart lighting adds convenience but typically has less effect on sale price unless it forms part of a more comprehensive home automation setup with documented installation certificates.

What is the most cost-effective smart electrical upgrade to start with?

For most homes, a smart thermostat is the most cost-effective first upgrade. Devices like the Nest Learning Thermostat or Hive Active Heating typically cost between 150 and 250 pounds fully installed. Better heating control can reduce energy bills noticeably, particularly in larger properties with older boiler systems and poor existing controls. Most qualified electricians can install one in under two hours, making it a low-disruption, high-return starting point for anyone new to smart home technology.
