Structured cabling that passes
first time, every time.
DNRB Solutions installs, tests and certifies data, fibre and AV infrastructure for commercial and institutional sites — from single-room fit-outs to multi-storey new builds. Based in Hertfordshire, working nationwide.
Six disciplines, one team on site.
We scope, install and sign off every layer of the cabling infrastructure — so there's one point of contact from first survey to final certificate.
Data Cabling
Cat6 and Cat6A copper infrastructure for offices, education and residential fit-outs — first fix through to patch panel termination.
Fibre Optic Installation
Singlemode and multimode fibre backbones, splicing and termination for inter-building links, risers and data centre connectivity.
AV Installation
Structured cabling to support boardroom, classroom and auditorium AV systems, coordinated with the wider M&E programme.
Site Auditing & Surveys
Pre-installation surveys and existing-infrastructure audits, with clear reporting to inform design, pricing and programme.
Testing & Certification
Fluke DSX permanent link and channel testing against TIA-568 and ISO 11801, with manufacturer warranty submissions.
Commissioning
Final sign-off, labelling, as-built documentation and O&M packs so the client inherits a fully accountable system.
Survey to certificate, in four stages.
Site survey & design
We walk the site, confirm containment routes and outlet positions, and price against the actual building — not a generic spec.
First and second fix
Containment, cable pulls and termination carried out by our own engineers, sequenced around the wider trades on site.
Test & certify
Every link tested with Fluke DSX equipment against TIA-568 / ISO 11801 standards before it's signed off.
Commission & document
Labelling, as-built drawings and full test result sets handed over, with manufacturer warranty registered where applicable.
Rooted in Hertfordshire, working nationwide.
Our base gives us fast reach across London and the South East, and we regularly run multi-day site programmes further afield across the UK.
- Hertfordshire Home base — same-week callout
- London & M25 Regular programme
- South East & East Anglia Regular programme
- Midlands Multi-day site works
- North & Scotland Scheduled projects
Fit-outs, new builds and live environments.
Installation and commissioning in live facilities.
We install and commission copper and fibre infrastructure within data centre environments, working to the site's own access, change control and escort procedures.
Data centre work has its own rules. Change windows are fixed, routes are already congested, and there is no scope for a cabinet to be left half-finished at the end of a shift.
We work to the facility's procedures, not our own — inductions, permits, escorted access and out-of-hours windows where the site requires it.
Everything is tested, labelled and recorded before we leave, so the records match what is physically in the rack.
Copper installation
Cat6 and Cat6A cabinet-to-cabinet runs, patch panel termination and structured patching within racks.
Fibre installation
Singlemode and multimode fibre, pre-terminated trunks, splicing and termination between racks and rows.
Containment & routing
Cable management within and between cabinets, kept clear of airflow and worked around existing services.
Testing & commissioning
Full test and certification of every link, with labelling and records handed over to match the installed system.
When the network goes down, it can't wait until Monday.
A failed link, a damaged fibre or a cabinet fault doesn't keep office hours. We operate an out-of-hours callout service for existing and new clients across the UK — whether we installed the system or not.
- Damaged or severed fibre and copper runs
- Failed links following building or fit-out works
- Faults traced, tested and certified after repair
- Temporary reinstatement to get you running again
Call directly for urgent faults. For anything non-urgent, use the enquiry form below and we'll come back to you in normal working hours.
A contractor-run business, on the tools.
DNRB Solutions Limited is a Hertfordshire-based structured cabling contractor working across the UK. We're director-led — the people who price your job are the people who turn up to install it, so nothing gets lost between the quote and the site.
We came up through the M&E trades, which means we understand how cabling has to fit around the wider programme: containment shared with other services, access constraints on live buildings, and handover dates that don't move.
Every installation is tested and certified before we sign it off, and we submit for manufacturer warranty where the client wants it — so the system you inherit is backed, documented and accountable.
Directors on site
You deal with the same people from survey through to handover — not a call centre and a rotating crew.
Certified, not just installed
Fluke DSX testing on every link, results issued in full, with manufacturer warranty submissions where required.
Priced off the real building
We survey before we quote, so the figure you get reflects the actual routes and access — not a guess off a drawing.
Used to working around other trades
M&E background means we sequence our works to suit the programme rather than fight it.

Send over the location, rough scope and timescale and we'll come back with next steps — usually a survey date or a budget figure to work with.
