Freeholder Consent Guide for Structural Works

Removing a wall in a leasehold flat can look straightforward on a builder’s quotation. Yet the work may affect a loadbearing wall, fire separation, acoustic performance, shared services or the structure retained by the freeholder. This freeholder consent guide explains what consent is likely to involve, why structural evidence matters, and how to avoid an expensive delay once works are due to begin.

Start with the lease, not the design

The lease is the starting point for any proposed alteration. Most residential leases distinguish between minor internal decoration and alterations that affect the structure, external appearance, layout, services or shared parts of the building. The wording varies, but structural work will commonly require the freeholder’s written consent, often issued as a formal Licence to Alter.

Do not assume that work inside your own flat is automatically permitted. A wall between a kitchen and living room may be loadbearing. Removing a chimney breast may affect masonry continuing through the flats above or below. Installing new steelwork can introduce loads into shared walls and foundations. Even where the structure is not directly altered, moving drainage, ventilation or gas services can trigger separate requirements.

Your managing agent may provide an alterations pack setting out the application process, fees and documents required. This is useful, but it does not override the lease. If there is uncertainty about what the lease permits, take legal advice before committing to a contractor or ordering materials.

What freeholder consent is designed to protect

Freeholder consent is not simply an administrative obstacle. The freeholder has a duty to protect the building, other leaseholders and the long-term value of the property. They need confidence that the proposed works will not compromise structural stability, create a fire risk, damage common parts or leave the building with poorly documented alterations.

For a structural proposal, that confidence usually comes from project-specific engineering information. Generic sketches, a contractor’s assurance that a wall is non-loadbearing, or calculations prepared for a different property are rarely sufficient. Victorian and Edwardian conversions, mansion blocks and purpose-built flats can all conceal variations in wall construction, joist direction, chimney support and previous alterations.

A proper structural design identifies the load path: how the building’s weight is carried from roof and floors, through walls or beams, into the foundations. It then shows how that load path will be maintained once the proposed opening, removal or alteration is complete.

Typical projects requiring consent

Consent requirements depend on the lease and the managing agent’s policy, but applications commonly arise for wall removals, kitchen reconfigurations, loft conversions, rear extensions, chimney-breast removals, new stair openings and bathroom relocations. Works involving steels, lintels, padstones, new foundations or alterations to a party wall deserve particular attention.

Some freeholders also require consent for flooring changes, especially where a hard finish may affect acoustic insulation. Others require approval for new ventilation routes, external flues, replacement windows or works affecting the façade. A careful application considers the complete scope, rather than focusing only on the most obvious structural element.

The documents a strong application usually needs

There is no single national checklist, but a well-prepared application normally combines legal, technical and practical information. The more complex the work, the more detail the freeholder’s surveyor is likely to request.

For structural alterations, this often includes existing and proposed drawings, structural calculations, structural drawings, a specification of the proposed work and a method statement. The calculations establish that the proposed beam, connections, bearings and supporting elements are suitable. The drawings allow the freeholder, contractor and Building Control body to understand exactly what is to be built.

It is also sensible to provide the contractor’s details, proof of public liability insurance and an outline programme. Where the work may create noise, vibration, dust or access issues, a clear schedule and site-management plan can reduce concerns from both the managing agent and neighbouring residents.

A freeholder may appoint its own surveyor or engineer to review the submission. The lease or alterations policy may allow the reasonable cost of that review to be charged to the leaseholder. This can feel frustrating, but it is a common feature of Licence to Alter applications. Budget for it early rather than treating it as an unexpected cost after the design is complete.

Why bespoke engineering evidence makes a difference

A structural package should be based on an inspection of the actual property and the proposed arrangement. The engineer may need to inspect wall thicknesses, floor and ceiling construction, the direction of joists, chimney configuration, signs of historic movement and likely bearing locations. In some properties, small opening-up works are needed before the final design can be confirmed.

This level of investigation protects more than the consent process. It gives the builder clear installation information, supports a Building Control application and creates an evidence trail for a later sale, remortgage or insurance query. Laytoe Structures prepares tailored structural calculations and drawings for these situations, with practical details that can be reviewed by Building Control and a freeholder’s professional team.

Consent, Building Control and the Party Wall Act are separate matters

One of the most common mistakes is treating a single approval as permission for everything. Freeholder consent, Building Regulations approval and Party Wall matters are separate legal and technical processes. One does not replace another.

Building Control is concerned with compliance with the Building Regulations. For structural work, this includes whether the design safely supports relevant loads and whether elements such as fire protection, insulation and ventilation meet the required standard. Building Control approval does not give a leaseholder authority to alter a property contrary to the lease.

The Party Wall etc. Act 1996 may apply where work affects a shared wall, excavates close to a neighbouring building or involves certain structural works to a party structure. Party Wall notices and awards are matters between adjoining owners. They may apply in addition to freeholder consent, particularly in converted buildings, but the correct route depends on ownership arrangements and the scope of work.

Planning permission may also be relevant for extensions, external alterations, roof works or changes affecting a conservation area. Treat each requirement as a separate workstream and allow time for all of them.

A sensible order for securing approval

The fastest route is rarely to submit a vague proposal and hope that details can follow later. Freeholders and managing agents generally need enough information to make an informed decision. An incomplete application can lead to repeated questions, additional professional fees and a stalled programme.

Begin by reviewing the lease and requesting the managing agent’s alteration requirements. Next, develop the design sufficiently for a structural engineer to assess the proposal. Once the structural survey, calculations and drawings are ready, coordinate them with architectural drawings and the intended Building Control route. Then submit the complete consent application before booking irreversible works.

If the freeholder’s surveyor comments on the design, respond through the relevant professional rather than asking a builder to make unverified changes on site. A change to beam size, bearing detail or connection arrangement can affect both the calculations and the approval documentation.

Avoid the shortcuts that cause problems later

Starting without written consent is a serious risk. The freeholder may require the works to stop, request retrospective evidence, impose conditions, or in severe cases seek reinstatement. Retrospective approval can be more difficult because the engineer may be unable to see concealed bearings, fixings or support details once finishes have been installed.

Another avoidable problem is changing the scope during construction. For example, an opening may be made wider after steelwork has been designed, or a contractor may move a support to accommodate kitchen units. These decisions can invalidate the original structural design. Any meaningful change should be reviewed before it is built.

Keep a complete project record: the Licence to Alter, approved drawings, structural calculations, Building Control correspondence, completion documentation, contractor warranties and photographs of concealed structural stages. Future buyers, lenders and insurers often want reassurance that the alteration was properly designed, approved and completed.

When to ask for advice

Seek structural input early if you are removing masonry, altering floors, opening a staircase, extending a flat, taking out a chimney breast, or dealing with visible cracks near the proposed works. Early advice does not always mean a more complicated scheme. In many cases, it identifies a practical beam arrangement, reduces disruption and prevents the application being rejected for lack of evidence.

A well-supported request for consent gives the freeholder a clear basis for approval and gives you a safer route to construction. That preparation can protect the value, saleability and mortgageability of your flat long after the new layout is finished.
