EWS1 Surveyor in Marylebone: Form & External Wall Advice

EWS1 form & external wall advice across Marylebone

EWS1 forms may be requested by lenders or valuers where external wall information for a residential building in Marylebone is incomplete or unclear. We support the EWS1 process by reviewing external wall evidence, explaining the relationship with FRAEW and PAS 9980, and coordinating competent professional input where required.

An EWS1 form is lender/valuation-facing information about external wall systems. It is not a life-safety certificate and does not replace statutory fire risk assessment or wider building safety duties. We work with managing agents, freeholders and residents' associations across Westminster to identify the evidence already available, define the right next step and link EWS1 advice with PAS 9980, facade investigation or remediation where needed.

Common Building Issues in Marylebone

Where an EWS1 does apply to a Marylebone building, it is a block of flats among the Georgian townhouses, mansion flats, mews houses and medical quarter properties rather than one of the houses; the form records external wall build-up and attachments, and we establish those by inspection where the records cannot.

Planning and Conservation in Marylebone

Harley Street Conservation Area and Portman Estate Conservation Area with many Georgian listed buildings; Westminster City Council applies the most stringent controls outside Kensington and Chelsea. Where an external-wall review does lead to works on a Marylebone block, those controls apply to the remediation too: replacement render, cladding or windows can need consent, and we specify to satisfy the fire strategy and the local design position together.

Getting to Marylebone

Our surveyors cover Marylebone and the surrounding Westminster area. The area is accessible via Baker Street (Metropolitan/Circle/Hammersmith/Jubilee/Bakerloo), Bond Street (Central/Jubilee/Elizabeth line), and our team carries out regular inspections across Marylebone W1U.

The thresholds behind the advice

Mid-rise stock is where the thresholds do the most work. From 11 metres or five storeys, a self-contained building with two or more dwellings can be a ‘relevant building’ for the Building Safety Act 2022’s Part 5 leaseholder protections (section 117, subject to its exclusions for leaseholder-owned buildings); at 18 metres or seven storeys the section 65 higher-risk regime begins. EWS1 requests in this band are answered with a PAS 9980:2026-based appraisal, and government and RICS guidance is that buildings below 11 metres should rarely need an EWS1 at all.

The local context on this page is drawn from public planning and conservation sources, together with the statutory external-wall and building-safety framework EWS1 work sits in: City of Westminster conservation areas; City of Westminster Article 4 directions; Building Safety Act 2022; Fire Safety Act 2021; Regulatory Reform (Fire Safety) Order 2005. These sources support the area context; they do not replace inspection of a named building or a fire-risk assessment, and the exact building-safety and planning position should be confirmed for the address.

Marylebone sits inside our London coverage, so an instruction here is quoted on the same published scale as the rest of London rather than on a separate local rate.

Typical fees: EWS1 Form & External Wall Advice instructions in London typically start from £5,000 plus VAT; we confirm a fixed fee after scoping the building and the brief.

The EWS1 Form & External Wall Advice London for Flats, Leaseholders & Managing Agents page sets out the full scope behind that figure.
