How much electricity does a typical CCTV system use per year?

A small system of around four PoE cameras and a recorder typically draws somewhere in the region of 30 to 60 watts continuously, which adds a modest but noticeable amount to an annual electricity bill, generally a good deal less than a fridge freezer.

How often should I expect to replace the hard drive?

Most surveillance rated hard drives last somewhere between two and five years under continuous recording, depending on quality and how full the system runs. Checking drive health at an annual service helps catch a failing drive before it causes gaps in footage.

Is cloud storage necessary for a rental property?

Not necessarily. Local recording on a good hard drive is often sufficient for most landlords, and a cloud subscription is really only worth the extra ongoing cost if you specifically want off site backup in case the recorder itself is damaged or stolen.

Does having CCTV reduce my landlord insurance premium?

It can in some cases, but this varies significantly by insurer and policy, so it is worth asking your provider directly rather than assuming a discount. Some insurers view CCTV favourably as a deterrent and evidence tool rather than offering a set reduction.

The ongoing running costs landlords should budget for

Landlords often budget carefully for the upfront cost of fitting CCTV at a rental property but give far less thought to what it costs to keep running year after year, which matters when you are pricing it into service charges or your own annual outgoings. The good news is that a wired PoE system is genuinely cheap to run day to day, but there are a handful of recurring costs worth planning for properly.

This guide breaks the ongoing cost of CCTV down into the pieces that actually add up over time: electricity consumption, hard drive replacement cycles, periodic servicing, any broadband or cloud storage subscription, and how CCTV can interact with your buildings insurance. None of these are large individually, but together they form the true cost of ownership beyond the installation invoice.

Whether you manage one rental property or a small portfolio, understanding these figures helps you set realistic expectations with tenants or letting agents about what the system covers, and avoids an unwelcome surprise a few years in when a hard drive or camera needs replacing.

Five Minutes of Prep Saves Money

Check the power rating of your recorder and cameras

Look at the wattage printed on the recorder's power supply and each camera's PoE draw, typically a few watts each, to estimate roughly what the system costs in electricity annually.

Note when the hard drive was last replaced

Hard drives in continuously recording systems typically last two to five years, so keep a simple record of installation and replacement dates for each property.

Book an annual service rather than waiting for a fault

A yearly check of cameras, cabling, recorder and storage catches small issues while they are cheap to fix, rather than after a tenant reports a fault.

Review whether you actually need cloud storage

Local recording on a hard drive is included in most systems at no ongoing cost, so only add a cloud subscription if you specifically need off site backup or remote access beyond what the app already offers.

Ask your insurer directly about CCTV

Contact your buildings or landlord insurance provider to ask whether a working CCTV system affects your premium or excess, rather than assuming it automatically reduces cost.

Factor broadband reliability into the running cost

If remote viewing and any cloud backup depend on the property's broadband, a poor or unreliable connection can effectively be part of the ongoing cost of a fully functioning system.

Cost Drivers in Plain English

Electricity consumption

A typical small CCTV system with a recorder and four PoE cameras draws in the region of 30 to 60 watts continuously, which works out as a modest but real addition to the annual electricity bill.

Hard drive replacement cycles

Because recorders write to the drive constantly, hard drives are a wear item rather than a one off cost, with typical UK replacement costs for a decent surveillance rated drive running from roughly 60 to 150 pounds depending on capacity.

Periodic servicing

An annual check of cameras, cabling and recorder health is a sensible ongoing cost for a landlord, similar in principle to servicing a boiler, and helps avoid larger repair bills later.

Cloud storage or subscription features

Optional cloud backup or advanced app features typically come with a monthly or annual subscription on top of the hardware, which is worth weighing against the cost of simply keeping local storage well maintained.

Broadband and remote access reliance

While local recording does not depend on broadband, remote viewing and any cloud element does, so a poor connection at the property can effectively add cost in troubleshooting or an upgrade.

What a Fair Quote Should Cover

You want to know the true annual cost of ownership beyond the installation price

You are budgeting CCTV into a rental property's running costs or service charge

You are unsure how often a hard drive genuinely needs replacing

You want to know whether cloud storage subscriptions are worth adding on top of local recording

You are wondering whether CCTV affects your landlord insurance premium one way or the other

When to Ask for a Written Quote

A hard drive is approaching or past the typical two to five year lifespan without being checked

You want a clear annual running cost estimate to include in a service charge or budget

The system has never had a proper service since installation

You are unsure whether existing broadband at the property is adequate for remote viewing needs

You want advice on whether cloud storage is genuinely worth adding for your properties

Keeping the cost down

Set a simple annual reminder to service the system and check hard drive health before it becomes a fault a tenant has to report to you. Keep a basic log per property of installation date, last service and last hard drive replacement so running costs are predictable rather than a surprise.
