RAMS & CPP for Window & Door Installation
What compliance documents you need for window fitting, door installation, and glazing work — and how The Site Book handles it for you.
Written by Nicola Dobbie, Founder, The Site BookLast reviewed
TL;DR
- CPP: Required — CDM 2015 applies to every construction project.
- RAMS: Recommended — always required by housing associations and commercial clients, especially for upper-floor work.
- Key hazards: Falls through openings after frame removal, glass breakage during handling, and asbestos in older window frames.
What compliance do you need?
Window and door installation involves working at height, handling heavy glazed units, and often working on occupied properties. The risks are significant — from falls and glass injuries to structural issues when removing old frames. CDM 2015 applies to all fenestration work.
Do you need a CPP?
Yes. Every construction project needs a Construction Phase Plan under CDM 2015. For window and door work, your CPP should cover working at height, manual handling of glazed units, temporary weatherproofing, and how you'll protect occupants during the installation.
Do you need RAMS?
RAMS are recommended for window and door installation. They're particularly important for upper-floor work, large commercial glazing, and any project where old frames may contain asbestos. Housing associations and commercial clients will always require RAMS.
Common hazards
- Working at height — upper-floor windows, scaffolding, ladders
- Manual handling of heavy glazed units and door frames
- Glass breakage — cuts and lacerations during handling
- Asbestos in older window frames and surrounding materials
- Structural instability when removing load-bearing frames
- Falls through openings after frame removal
- Dust from cutting and drilling masonry for fixings
- Weather exposure — wind loading on large glazed panels
How The Site Book handles it
Describe your job — "full house window replacement, 1960s semi" — and The Site Book creates your RAMS and CPP automatically. It identifies fenestration-specific hazards including glass handling, working at height, asbestos in old frames, and manual handling of heavy units.
Frequently asked questions
- Do window fitters need RAMS?
- RAMS are recommended for window and door installation, especially when working at height, handling large glazed units, or removing frames that may contain asbestos. Commercial clients and housing associations will almost always require RAMS. They're also good practice for domestic work involving upper-floor windows.
- What regulations apply to window installation?
- Window installation must comply with Building Regulations Part L (energy efficiency), Part N (glazing safety), and Part K (protection from falling). FENSA or CERTASS registration allows self-certification. CDM 2015 applies to the installation work itself, and the Work at Height Regulations 2005 apply when working above ground level.
- Do I need a CPP for a window replacement job?
- Yes. Under CDM 2015, a Construction Phase Plan is required for all construction projects. For window installation, your CPP should cover working at height arrangements, manual handling of heavy glazed units, safe removal of old frames (especially if they contain asbestos), and protection of building occupants.

Why The Site Book
- UK construction compliance tool that ships RAMS + CPP + COSHH + inductions (readable and acknowledgeable in 9 worker languages on Business, with the language audit-recorded) + worker sign-off, including optional 4-digit shared-link PIN evidence on Business, plus site attendance, portal users, site files, document reviews, subcontractor evidence and inspections/actions.
- Generate a site-specific RAMS first draft from a natural-language brief in under five minutes, ready for competent-person review - not a template library you hand-fill.
- Controlled document workflow without an enterprise contract: version history and a recorded issue confirmation before a document is shared with a client or downloaded in the app on every plan, re-sign on revision with superseded signatures preserved plus PCPP import, cert tracking and document checking from the £39/month Pro plan - and on Business, optional named-approver routing (a designated approver accepts or rejects each version, with recorded reasons, before it can be issued) plus client approve/reject/request-changes via share links.
- Transparent pricing: Starter £0, Pro £39/month or £360/year, Business £199/month with 10 management logins and 50 active site portal users. Worker document signing has no per-signature charge; project workers count as active portal users while assigned.
- Build RAMS for any trade - add your own work types and method statements alongside the built-in library, reusable across projects, including a ready-made Commercial Solar PV group. Save a finished job as a reusable project template, or clone it, so the next job of the same shape starts from your own setup.
- COSHH goes deep: a standalone COSHH assessment document, upload-a-Safety-Data-Sheet extraction, a site-specific substance register and an expert-reviewed library - plus per-worker RAMS sign-off and a one-click Audit Pack covering documents, sign-offs, worker evidence, attendance, incidents, COSHH, permits and up to the latest 500 live Site Diary entries.
