What should County Londonderry projects plan for?
In Derry, installations are often completed in a few days, and we can usually start on site soon after drawings are signed off because the survey answers the practical questions early.
Where a Derry building has a managing agent, we provide method statements, risk assessments and drawings in advance so the licence for alterations is not held up.
How much do fire rated partition walls cost in County Londonderry?
The required duration (30, 60 or 90 minutes), number of fire board layers, wall height and the extent of fire stopping around services and at the head set the price. Typical lead time: 1–3 weeks. Guide prices, supply and install — fixed after a free survey.
Why choose us in County Londonderry?
Built to the tested system
We follow the manufacturer's tested details for studs, boards, fixings and head, so the wall achieves the classification it is meant to have.
Penetrations planned
Services crossing the wall are coordinated in advance and sealed with tested products, which is where most fire walls actually fail in inspections.
Tested systems, documented
We use manufacturers' tested partition systems and hand over the relevant performance and test evidence at completion.
Tidy, protected sites
Floors and finishes are protected, waste is removed and the area is cleaned before handover.
The most common failures are not the boards but the gaps. Cables, pipes and ducts passing through the wall, sockets and back boxes, deflection heads and junctions with the façade all need fire stopping that is compatible with the wall's rating. We plan penetrations with your M&E contractor, use tested fire-stopping products and record what was installed, with photos taken before the second side is closed. At handover you receive the system classification and the fire-stopping record, which your fire risk assessor and Building Control will want to see.

Fire Rated Partition Walls in County Londonderry: FAQs
How much do fire rated partition walls cost in Derry?
Our guide price for fire rated partition walls is £75–£125 per m², supply and install, excluding VAT. The final price for a Derry project depends on the measured size, doors, glass or board specification and access, and is fixed after the free survey.
How soon can you start on a Derry project?
Typical lead time for fire rated partition walls is 1–3 weeks from signed-off drawings, mostly because materials are made to measure. Installation itself is usually a matter of days for a typical office, and we can phase work around a Derry office that stays open.
What makes a partition wall fire rated?
A partition wall is fire rated when it is built to a manufacturer's tested system, using the specified studs, fire-resistant boards, insulation, fixings and head detail, and installed exactly as tested. Every service penetration must also be fire stopped with compatible tested products. Using fire board alone does not make a wall fire rated.
How long does a fire rated stud wall last in a fire?
Office fire walls are commonly classified for 30, 60 or 90 minutes, such as EI 30 or EI 60. That figure is the time the tested wall maintained integrity and insulation in a standard furnace test. The duration you need is set by the building's fire strategy and Approved Document B.
Whether your Derry project is a single room or a whole floor, we will survey, design and install your fire rated partition walls with one team.
