O&M Manuals & Handover Documentation
Send us your files. We produce the documents.
Upload your drawings, certificates and branding — we turn them into handover-ready O&M manuals and CDM Health & Safety files, produced remotely and delivered as searchable digital documents.

What We Do
Documentation, delivered remotely.
We focus on the documentation that gets buildings handed over and retentions released — one deliverable or the full set, project by project.
01
O&M Manuals
Operation & Maintenance manuals compiled to BSRIA BG 79, CDM and employer’s requirements — indexed, cross-referenced and client-ready, so handovers land first time and retention isn’t held up waiting on a manual.
02
H&S Files & CDM Documentation
CDM Health & Safety Files, RAMS and supporting compliance documentation — compiled and reviewed to the same handover-ready standard, ready for client sign-off.
What It Costs
Simple, published pricing.
Fixed prices, no quote-chasing. Pick the tier that fits the job — every project is confirmed in writing before we start.
Essential
from £350
Single system or a small, simple project. O&M manual to your template, delivered as a searchable PDF.
Standard
from £950
Typical commercial fit-out with multiple M&E systems. O&M manual plus a CDM Health & Safety file, indexed and cross-referenced.
Complete
from £2,500
Large or multi-system projects. Everything in Standard, plus asset register, Regulation 38 fire-safety information and BREEAM / CIBSE TM31 as needed.
Add-ons available individually — standalone H&S file, asset register, Regulation 38 pack, CIBSE TM31 log book and fast-track turnaround. Prices exclude VAT. “From” is the floor for the simplest job in each tier; larger jobs are scoped up and confirmed in writing first.
