The purpose of Skyline is to make the UK much safer. It's simply put, there are just not enough buildings that have the highest standard of fire stopping or passive fire protection fitted. And it's my purpose and Skyline's purpose to make sure that we change that. We want every building to be as safe as possible. We want every resident, every tenant, every homeowner who lives in a building, a high-rise building, to be as safe as possible and to be safe from the risk of fire. We've all seen in the news what happens when buildings aren't correctly fire safe. And no one wants that to happen. Our purpose is to make sure that that doesn't happen again.

See the London page →Thames Valley / M4 corridor
Firestopping across Reading and the wider M4 corridor, worked from our Henley-on-Thames base:
- Reading
- Henley
- Newbury
- Maidenhead
- Windsor
- Slough
- Oxford
- Swindon
- Watford
Who it’s for
- HRB property developers Higher-risk residential buildings of 18 metres or seven storeys with two or more residential units get Gateway-ready evidence as the work goes in. Other multi-occupied residential schemes over 11 metres get the same evidenced installation, under the separate fire-safety duties that apply at that height.
- Managing agents Occupied buildings, surveys and remedials. Flexible, pragmatic and collaborative.
- Commercial landlords Hotels, care homes and high-end projects. Compliance you can defend, with an audit-ready Golden Thread evidence record.
The regional schemes national tier-one firms overlook. Delivered with Q-Mark certification and item-level evidence.
Before: a regional scheme where firestopping is squeezed, unevidenced, and no one will certify it, so the handover cannot be defended. After: tested systems, evidenced before cover-up and Q-Mark certified, so the work stands up when building control, BSR and insurers ask how it was done. We treat that work the way the landmarks are treated. Five years, 54 companies, ~50% bid-win rate.

Get clear advice on your project
Getting in touch starts with a free, no-obligation conversation: we discuss your building, your programme and what compliance actually requires. If it makes sense, we agree the next step: scope, fee and timing first, then the team that installs and evidences the work gets started.
BM TRADA Q-Mark third-party certification: independent proof, not our word for it.
Fire protection near me — firestopping coverage across Greater London and the M4 corridor
Certified firestopping with an item-level evidence record stands up when building control, the Building Safety Regulator or an insurer asks how the work was done.
Skyline Firestopping is the specialist firestopping and compartmentation contractor for Greater London and the Thames Valley / M4 corridor, working from a base in Henley-on-Thames. Across that area the company surveys, installs and evidences fire protection for higher-risk buildings at 18 metres or seven storeys, other schemes over 11 metres where stricter checks apply, occupied buildings that need remedial work, and high-end commercial schemes such as hotels and care homes.
The regular coverage runs through Reading, Slough, Maidenhead, Windsor, Newbury, Oxford, Swindon and Watford, and into Greater London — see the dedicated fire protection london page — where landmark projects including the Gherkin, Grosvenor Square House and Olympic Park sit. Fire protection Oxford enquiries follow the same certified process as the rest of the corridor. What sets the service apart is item-level evidence and independent certification: every penetration, joint and cavity is photographed before cover-up, tagged, batch-traced and geo-located, and the work carries BM TRADA Q-Mark third-party certification.
Whether you're searching firestopping contractors near me or comparing firestopping and fire protection specialists across the corridor, the same certified team and evidence standard apply, wherever your building sits. Some buyers search fire stopping contractors near me or fire stopping near me. Different spelling, same certified team and evidence standard. A fire risk assessment Reading building relies on, or a fire risk assessment Oxford building relies on, is carried out by a qualified fire risk assessor, not by Skyline. Our item-level evidence record is built to support whichever assessor carries it out.
Skyline holds BM TRADA Q-Mark third-party certification for firestopping: independent, audited proof that installations are inspected against a recognised scheme, not just the company’s own assurance. That's what building control, the Building Safety Regulator and insurers expect for higher-risk work. Firestopping is concealed the moment it is covered up, so the only proof a seal was formed correctly is the certification behind it and the photographic record taken before cover-up.
For every firestopping and compartmentation installation, Skyline captures an item-level evidence record, not a single completion certificate at the end. Each penetration, joint and cavity is photographed before cover-up, then tagged, batch-traced and geo-located, so every seal traces back to its location, its system and the date it went in. That record is compiled into an audit-ready Golden Thread evidence pack, retained for 15 years: the format a duty-holder needs for a Gateway 2 submission and ongoing building-safety cases under the Building Safety Act 2022. Because it is captured as the work proceeds rather than reconstructed afterwards, it stands up when building control, the Building Safety Regulator or an insurer asks how a particular seal was formed.
Fire safety in higher-risk buildings, in numbers
Fire safety in higher-risk buildings is a measurable problem. Not an abstract one. Government figures put between 71,000 and 79,000 residential buildings in England in the 11-to-18-metre band where stricter checks apply.
The building-safety reforms behind these duties trace back to the Grenfell Tower fire of June 2017, in which 72 people died. And the risk is ongoing: Home Office data recorded 254 fire-related deaths in England in the year to December 2024, around 78% of them in the home.
For higher-risk buildings, firestopping installed to a tested standard and evidenced before cover-up is what turns a building's fire strategy from a drawing into something defensible.
