Every unattended site in Greater Manchester is a target for plant theft, cable stripping and fly-tipping, and the two most common answers are a solar-powered CCTV tower or a guard on the gate. Both work, but they solve slightly different problems at very different price points. Here is a straightforward comparison to help you decide before the first delivery of copper turns up.
A solar CCTV tower is a trailer or skid-mounted mast, usually 5 to 7 metres tall, carrying two to four cameras, infrared or thermal sensors, a loudspeaker and a 4G link. Its batteries are charged by solar panels, so it needs no mains supply, which matters on a plot where the electricity connection is months away. Detection is by motion or thermal trigger, and every alarm is checked by an operator in a monitoring centre who can issue an audio warning and call keyholders or the police.
A security guard is a person, ideally SIA licensed, who stays on site for the shift, does patrols, checks deliveries, signs visitors in and physically challenges intruders. A guard can stop someone cutting a Heras panel; a camera can only shout at them and record it. That difference is the whole decision in a nutshell.
Manned guarding in the North West is usually charged by the hour. Rates for a single SIA licensed officer vary with the contractor and the shift pattern, but a realistic range is £14 to £20 per hour. A site covered nights and weekends only, around 100 hours a week, lands at £1,400 to £2,000 per week. Round the clock cover with two officers can exceed £5,000 a week. Over a 40 week build that is a serious line in the budget.
A solar CCTV tower is normally hired at a weekly or monthly rate that includes the equipment, monitoring and 4G data. Expect somewhere between £180 and £350 per week per tower depending on camera spec, thermal detection and contract length, plus a delivery and set-up charge that depends on distance and access. One tower covers roughly a 100 to 150 metre radius in open ground, so a large or awkwardly shaped site may need two or three.
Towers are consistent. They do not get tired at 3am, they cannot be talked into opening the gate, and thermal detection picks up a person hiding behind a stack of blocks that a torch patrol would walk past. The recording gives you evidence for insurers and the police, and the audio challenge alone sees off most opportunists. Site managers also like the daytime benefit: you can check deliveries and progress from your phone.
Guards win when there is something a camera cannot do. High value plant that has to be locked away each evening, live traffic on a shared access road, a site next to a pub car park in Ancoats or Salford Quays where drunken intrusions are routine, or a client contract that demands a physical presence. A guard can also handle first aid, fire watch and out of hours deliveries, which no tower will ever manage.
The weak points are worth knowing too. Towers rely on a response; if your keyholder is 40 minutes away and police attendance is slow, determined thieves may have the fuel drained before anyone arrives. Guards have their own risks: lone workers on a dark site are vulnerable, sickness leaves gaps, and a poorly supervised officer can be asleep in the cabin.
Most contractor all risks policies ask what security is in place, and some now specify monitored CCTV or a guard for sites above a stated contract value. Ask your broker before you choose, because a tower that meets their wording can lower the premium enough to offset most of its hire cost. Keep the monitoring station certificate and any incident reports; insurers want to see them after a claim.
Solar towers need a clear patch of sky, so a site hemmed in by tall buildings around Deansgate or Piccadilly will need a tower with a hybrid fuel cell or a mains top-up in winter. Manchester's grey months mean solar output drops sharply from November to February, so ask the supplier how many days of autonomy the battery gives. You will also need signage to satisfy data protection rules, and the cameras must not overlook neighbouring homes beyond what is reasonable.
In practice many builds around Greater Manchester use a tower for the whole programme and add a guard only for the high risk weeks: the fortnight after the plant arrives, the period when copper and boilers are delivered, and the final fit-out when the property is nearly saleable. That gives you evidence and constant coverage for a few hundred pounds a week, with human presence only when the value on site justifies it.
Whatever you pick, get it on site before the first excavator, not after the first break-in. The cheapest security is the one that stops the theft that would have written off a month of programme.
The monitoring centre typically views the alert within a minute and issues an audio warning straight away. Physical attendance depends on who you nominate as keyholder or whether you pay for a mobile response service, which usually aims for 20 to 40 minutes in urban Manchester.
Usually not, because a trailer-mounted tower is treated as temporary site equipment rather than a structure. You do need appropriate signage and to make sure cameras are not pointed unnecessarily at neighbouring homes or the public highway.
One officer can patrol a compact site, but on anything over an acre with multiple access points the gaps between patrols become a problem. Pairing a single guard with a monitored tower is usually more effective than adding a second guard, and considerably cheaper.
