Your security company in Leeds
Trinity Secure provides security services across Leeds from our base at Ground Floor, Unit 4 Lakeside, Calder Island Way, Wakefield, about 10 miles south along the M1. Southern Leeds districts such as Stourton, Hunslet and Rothwell sit closer to us than to the city centre, and the M621 and ring road bring the rest of the city in range.
Leeds carries the region’s largest development pipeline: city-centre residential towers, the South Bank regeneration, student accommodation and big distribution space along the M1 and M62 and out at Thorpe Park and the Aire Valley. Every one of those sites needs a different mix of people and cameras, and we plan that mix with you rather than selling a single product.
You deal with one local team for guarding, dogs, patrols, keyholding and cameras: one site survey, one set of instructions and one number to call, 0113 350 1546, or email david@trinity-secure.co.uk.

Construction site security and CCTV in Leeds
Central Leeds sites are tight, overlooked and busy until late, so cover concentrates on gates, hoarding lines and materials stores. Out on the Aire Valley, Cross Green and Stourton, plots are wide and quiet after dark, and towers and dog handlers carry more of the load.
Our towers carry their own power: solar panels, a battery bank and a 4G link, so the cameras run from the first night on site. A monitoring operator watches every activation live, around the clock. Intruders are warned off with a live audio challenge, and if they stay, a response officer is sent and the police are called where needed.
We deploy the same week as standard and often the same day, subject to kit availability, access and the brief, and we move towers as phases open and close.
For tower specifications, hire terms and what to send us for a quote, see our guide to construction site CCTV and tower hire in Leeds. For timber-frame phases, add fire detection towers to the same plan, and for projects across the county see construction site CCTV towers in Yorkshire.
Manned guarding, K9 dog handlers and mobile patrols in Leeds
Manned guarding. Uniformed SIA officers who control access, check deliveries, protect staff and visitors and hold the site overnight, on day, night, weekend or round-the-clock rotas, with short-notice cover when something goes wrong. Officers cover city-centre schemes, reception and concierge posts, and gatehouses on logistics sites around the M1 and ring road. See manned guarding.
K9 dog handlers. A handler and trained dog search ground a camera cannot see, such as stacked materials, empty floors and dark corners, and few intruders stay once a dog unit is on patrol. Dog units suit large plots along the Aire Valley and compounds around Cross Green and Stourton. See K9 guard dog units.
Mobile patrols and keyholding. Licensed officers visit at set or unpredictable times to check locks, fences and compounds, and as your keyholder we attend alarm activations day or night so your staff stay at home. You get a record of every visit, with photos where relevant. Patrol rounds cover empty units and multi-site portfolios across south and east Leeds, with reports after every visit. See mobile patrols and keyholding.
Cover is rarely one thing. Many clients run a monitored tower all night, an officer on the gate by day and a dog handler at holiday periods or after a break-in. Every officer has our monitoring team behind them.
Leeds sites we protect
- City-centre and South Bank construction: residential, office and student schemes with tight compounds and late activity.
- Aire Valley, Cross Green and Stourton: large industrial and logistics plots with long boundaries and quiet nights.
- Thorpe Park and the M1 junctions: distribution and business-park sites with several gates and vehicle movements.
- Holbeck, Hunslet and Armley: mixed industrial land, conversions and redevelopment sites.
- Outer Leeds: Morley, Rothwell, Garforth, Pudsey, Horsforth and Seacroft projects and premises.
Vacant property security in Leeds
Leeds has a large stock of empty retail, office and industrial space waiting for re-letting or redevelopment. We protect it with monitored towers, alarm response, logged inspections and keyholding, so the building stays secure and insurable while it is empty.
Landlords, agents and insolvency practitioners can combine monitored towers, video-verified alarms and patrol inspections under one plan. See vacant property security in Yorkshire for insurer requirements and how a void property handover works.
How we set up security in Leeds
- Tell us about the site: call 0113 350 1546 or email with the postcode, site type and the date cover needs to start.
- Free site survey: we walk the gates, boundaries, plant, stores and buildings and agree what needs protecting and when.
- A written plan: the mix of officers, dogs, patrols and cameras, the hours of cover, and who we contact when something happens.
- Deployment: same-week as standard and often the same day.
- Review: we adjust the plan as the site changes, from groundworks to handover or from empty to re-let.

How far is Leeds from your base?
Leeds is about 10 miles north of our base at Calder Island Way, Wakefield, via the M1. South Leeds districts such as Stourton, Hunslet and Rothwell are closer still.
Do you supply SIA-licensed officers in Leeds?
Yes. Our security officers in Leeds hold SIA licences and are briefed on your site’s procedures before they start, and our K9 teams are licensed handlers with trained dogs. Officers are backed by our 24/7 monitoring team.
How quickly can you put security on a Leeds site?
Same-week deployment is standard and same-day is often possible, depending on equipment and officer availability, site access and the brief. Ring 0113 350 1546 with the site postcode and the date you need cover from.
Can you protect a Leeds construction site without mains power?
Yes. Our CCTV towers and fire detection towers run on solar power with battery backup and 4G, so they protect a compound before mains power or a phone line is connected.
Which areas of Leeds do you cover?
All of Leeds, including the city centre, South Bank, Holbeck, Hunslet, Cross Green, Stourton, the Aire Valley, Thorpe Park, Armley, Kirkstall, Seacroft, Morley, Rothwell, Garforth, Pudsey and Horsforth.
Covering Leeds and the surrounding area
Leeds is about 10 miles up the M1 from our Calder Island Way base, so south Leeds sites are often closer to us than they are to the city centre. Nearby, see security services in Wakefield, security services in Bradford, security services in Huddersfield, or our wider Yorkshire coverage.
