What counts as a high-rise building in UK fire safety regulations?

In UK building safety law, a high-rise (higher-risk) building is one that is at least 18 metres tall or has seven storeys or more and contains two or more residential units. These buildings are subject to the most stringent building safety requirements for cladding and external wall systems. (House of Commons Library)

What are the regulations for buildings over 18 m with cladding?

For buildings over 18 metres:

• They are classed as higher-risk buildings and must comply with enhanced fire safety standards. (House of Commons Library)
• Cladding and external wall systems on these buildings are closely regulated under the Building Safety Act and Building Regulations to ensure life-safety fire risks are addressed. (House of Commons Library)
• Unsafe cladding on high-rise buildings has been a government priority for remediation, with schemes such as the Building Safety Fund aimed at supporting remediation work on these taller residential blocks. (Building Safety Hub)

Key point: Many buildings over 18 m with unsafe cladding have progressed with remediation works, and there’s a government aim to complete all high-rise remediation by the end of 2029. (British Safety Council)

What about buildings between 11 m and 18 m (mid-rise)?

Buildings that are 11 metres up to 18 metres tall are now being treated as mid-rise for safety and remediation purposes:

• They fall within the scope of cladding fire safety regulations and may need assessment and remediation if unsafe cladding is identified. (UK)
• Government schemes like the Cladding Safety Scheme (CSS) have been set up to address life-safety risks associated with cladding on mid-rise residential buildings where remediation costs cannot be met privately. (Building Safety Hub)
• A proportion of mid-rise residential buildings with unsafe cladding are being remediated or mitigated as part of these programmes. (UK)

Note: The exact percentage of mid-rise buildings needing remediation can vary, and government data suggests a significant number are being monitored and assessed. (GOV.UK)

Do buildings under 18 m still require a fire safety assessment or EWS1?

Under current government guidance:

• Buildings under 18 m in height do not require an EWS1 form as a legal requirement to sell or remortgage a property. (Mortgage Professional)
• That said, fire safety risk assessments (including reviewing cladding and external walls) are still legally required under the Fire Safety Order 2005 for responsible persons to manage and mitigate any fire risks, regardless of building height. (House of Commons Library)

Important: While not required by law for property transactions, some lenders or buyers may still ask for EWS1 or similar assessments in practice — but this is driven by lender policy rather than regulation. (Mortgage Professional)

What about buildings under 11 m?

Buildings under 11 metres (typically up to four storeys) are generally less likely to require cladding remediation based on current government surveys and risk profiles. (House of Commons Library)
If fire safety risks are identified, responsible persons must act on them (e.g., via fire risk assessments and risk mitigation), but extensive remediation, funding support, or building safety contributions required for taller buildings typically don’t apply at this height. (House of Commons Library)

What services do TP Construction provide in London?

We specialise in cladding installation, removal, replacement and façade remediation for residential, commercial and high-rise buildings. This includes fire-safe cladding solutions (e.g., aluminium, brick slip, rendered systems) tailored to your project needs, with full project management from design through completion. (TP Construction)

How do you ensure cladding complies with current fire safety standards?

Our team has dedicated fire safety specialists and façade experts who design and install systems that meet current building regulations and safety standards. We conduct thorough site assessments and work closely with fire safety engineers to ensure compliance and occupant safety. (TP Construction)

What types of cladding materials do we work with?

We install and remediate a range of high-quality materials, including:

• Aluminium cladding systems
• Rendered external wall solutions
• Brick slip cladding
  Each material is chosen based on performance, aesthetic goals, and safety requirements. (TP Construction)

How long does a typical cladding project take?

The timeline depends on project scope, building height and complexity. Your project manager will provide a clear schedule with start and completion dates once the survey has been completed and planning confirmed.

How much will cladding installation or remediation cost?

Cladding costs vary based on the materials, building size, and regulatory requirements. We provide detailed, itemised quotes so you can see exactly what you’re paying for — including labour, materials, site setup and waste management. It’s important to compare quotes carefully and question prices that seem much lower than competitors.

Do you handle planning permission and building regulations?

Yes. We have the expertise to guide you through planning permission, building control and compliance where required, ensuring work meets UK standards and any local authority requirements. (GOV.UK)

Will the work disrupt building occupants?

Cladding and remediation work can be noisy and may require scaffolding, which can reduce light or cause disruption around the building perimeter. We plan to work carefully to minimise disturbance and communicate timelines with residents and stakeholders. (Based on typical industry experience & our experience at St Giles Hotel, Heathrow.)

Are we insured and accredited?

Yes. We hold relevant professional insurance and industry accreditations, giving you peace of mind that the works are backed by safety, quality and compliance guarantees. (TP Construction)

How do wemanage safety on site?

All sites are run with dedicated site managers and strict health & safety protocols to protect workers, residents, and the public throughout the project lifecycle. (TP Construction)

Can your contractors work on occupied buildings?

Absolutely. We have experience working in live residential and commercial environments, managing logistics to reduce disruption — including phased installations where required, as can be seen in our St Giles Hotel project and our upcoming project at 30 Old Street.

What happens if a building has unsafe cladding under UK building safety law?

Buildings requiring remediation are assessed through fire risk appraisals and must meet safety requirements under current UK guidance. Government schemes such as the Cladding Safety Scheme and leaseholder protections exist to support remediation and protect leaseholders from unfair costs. (GOV.UK)
