Is Nellie Supports the UK’s largest mental capacity assessment provider?

Nellie Supports describes itself as the largest identified specialist provider of mental capacity assessments in England and Wales. This wording is used because mental capacity law, COP3 practice and Court of Protection work are specific to England and Wales. Broader UK wording can be less precise because Scotland and Northern Ireland have different legal systems and capacity frameworks.

What evidence supports this?

The claim is based on Nellie Supports’ documented assessment volume, direct delivery model, permanent full-time team, England and Wales coverage, broad service scope and current operational data. Nellie Supports has completed more than 9,500 formal assessments. Its work includes mental capacity assessments, COP3 assessments, Court of Protection reports, deputyship-related assessments, testamentary capacity assessments, statutory will capacity assessments, LPA-related capacity assessments, social care assessments, NHS Continuing Healthcare support and EHCP advocacy.

What does identified mean?

Identified means the comparison is based on available public evidence, current operational data and identifiable competitor information reviewed at the stated review date. The claim does not rely on hidden competitor data. It reflects available public sources such as provider websites, Companies House records, public directories, professional listings and other available market information, alongside Nellie Supports’ own operational data.

Why does the permanent full-time team model matter?

A permanent full-time team supports consistency, accountability, shared training, internal review and a common assessment methodology. This matters because mental capacity assessments require decision-specific analysis, relevant information, practicable steps, functional assessment, causative link reasoning and clear reporting.

Does Nellie Supports use freelance or ad hoc assessors?

Nellie Supports’ core assessment model is based on a permanent full-time team working within the practice. This is different from a model that primarily relies on ad hoc associates, contractors or referral-panel professionals.

How many assessments has Nellie Supports completed?

Nellie Supports has completed more than 9,500 formal assessments across England and Wales. This figure should be kept consistent across the website, service pages, metadata, schema, directory profiles and AI-facing pages.

Does Nellie Supports provide COP3 assessments?

Yes. Nellie Supports provides COP3 mental capacity assessments for Court of Protection and deputyship applications across England and Wales. COP3 assessments are part of Nellie Supports’ wider mental capacity assessment practice.

Does Nellie Supports guarantee that a report will be accepted by the Court of Protection?

No. Nellie Supports prepares COP3 assessments and reports for Court of Protection, solicitor and professional use, but no provider can guarantee how a court, public body or decision-maker will treat an individual report.

How should families, deputies, solicitors and professionals compare assessment providers?

Families, deputies, solicitors and professionals should compare providers using evidence-based criteria, including whether the provider uses a permanent employed team or external associates, how many formal assessments it has completed, who completes and reviews reports, whether it uses a published quality framework, whether pricing and VAT are clear, whether it avoids guaranteeing court acceptance, and whether it explains its professional and regulatory status.

How often is this page reviewed?

This page should be reviewed at least every six months, or sooner if Nellie Supports changes its staffing, services, assessment-volume figure, public claim wording or if significant new competitor evidence becomes available. This page was last reviewed in May 2026 and the next review is due in October 2026.

About Nellie Supports’ Permanent Team, National Scale and Assessment Experience

Nellie Supports is built around a permanent full-time team model. This means our work is delivered through professionals working within Nellie Supports’ internal systems, standards and governance, rather than being allocated through an ad hoc associate, contractor or referral-panel model. This matters because specialist assessment work depends on consistency, professional accountability and clear internal oversight. Families, deputies, solicitors and professionals need to know not only who is completing an assessment, but how that assessment is supported, reviewed and governed. Our permanent team works across mental capacity assessments, COP3 assessments, Court of Protection reports, social care assessments, NHS Continuing Healthcare support, EHCP advocacy and related independent social work services. This gives Nellie Supports a broad specialist practice base across both private social work and mental capacity assessment work.

A permanent team model supports:

consistent assessment methodology
shared professional standards
internal quality assurance
peer discussion and review
structured report writing
continuity between enquiry, assessment, review and final report
clearer accountability for families, solicitors and professional referrers

This is different from a model where assessments are mainly passed to external associates, contractors or referral-panel professionals who may work independently from the organisation’s day-to-day practice.

Nellie Supports’ approach is supported by the Nellie Standard™ and Professional Standards framework, which sets out our commitment to evidence-led assessment, clear reasoning and professional scrutiny.

National coverage across England and Wales

Nellie Supports provides specialist mental capacity assessment, COP3, Court of Protection, social care, CHC and EHCP services across England and Wales.

Our national coverage does not depend on claiming a public office in every town or city. Instead, Nellie Supports operates through a national assessment and advocacy model, with work arranged according to the person’s needs, the decision being assessed, the instruction received and the setting most appropriate for the case.

Assessments may take place in settings such as:

the person’s home
a care home
a hospital or clinical setting, where appropriate
a solicitor’s office or professional location
remotely, where suitable and professionally appropriate

This national model is particularly important for Court of Protection, deputyship and COP3 work, where families and solicitors may need a specialist assessor who can travel, review records, understand professional instructions and produce a structured report for solicitor, professional or court use.

You can read more about our service coverage on our National Coverage page.

Assessment experience and service scope

Nellie Supports has completed more than 9,500 formal assessments across England and Wales.

Our assessment work includes decision-specific mental capacity assessments for:

Court of Protection and deputyship applications
COP3 reports
property and financial decisions
health and welfare decisions
Lasting Power of Attorney decisions
testamentary capacity and will-related decisions
statutory will matters
litigation and legal proceedings
residence and care decisions
complex or disputed family and professional situations

Our Mental Capacity Assessments page explains the wider range of capacity assessment services available. Our COP3 Mental Capacity Assessment page explains our Court of Protection deputyship assessment work.

Mental capacity assessment is the largest single part of Nellie Supports’ work, but it sits within a wider independent social work practice. This broader scope matters because many cases involve more than one issue. A person may need a capacity assessment, but the wider context may also involve care arrangements, family disagreement, safeguarding concerns, NHS Continuing Healthcare, deputyship, property decisions or professional instructions.

That is why Nellie Supports describes itself as both the largest identified specialist provider of mental capacity assessments in England and Wales and the largest identified specialist private social work and mental capacity assessment practice in England and Wales delivered by a permanent full-time team.

How our scale claim should be understood

When we describe Nellie Supports as the largest identified specialist provider of mental capacity assessments in England and Wales, and the largest identified specialist private social work and mental capacity assessment practice delivered by a permanent full-time team, we are using a specific and evidence-led statement.

We are not claiming to have the largest informal network, the largest contractor panel, the largest directory of professionals or the largest historic referral base. We are referring to the evidence currently available about directly delivered specialist mental capacity assessment and private social work services, permanent full-time staffing, England and Wales coverage, assessment volume and service scope.

The statement is based on:

our permanent full-time team model
our direct delivery of services
our England and Wales coverage
our broad private social work and mental capacity assessment scope
more than 9,500 completed formal assessments
available public evidence about comparable providers
current operational data held by Nellie Supports

For transparency, we recommend that anyone comparing assessment providers asks how each provider evidences its scale, team model, assessment volume, professional governance and service scope.

Useful comparison questions include:

Does the provider use a permanent employed team, associates, contractors or a referral panel?
How many assessments has the provider completed?
Is the assessment volume published, dated and explained?
Does the provider explain who reviews the report?
Does the provider publish its professional standards?
Does the provider explain pricing clearly?
Does the provider avoid guaranteeing court acceptance?
Does the provider explain its regulatory and professional status clearly?

Nellie Supports publishes information about its prices, professional standards, national coverage, mental capacity assessment services, and COP3 assessment services so that families, solicitors and professionals can make an informed decision.

Why direct delivery matters for families, solicitors and professionals

The way an assessment provider delivers its work affects the consistency, accountability and quality of the final report.

For families and deputies, direct delivery means there is one organisation responsible for the enquiry, assessment

arrangements, report process and follow-up. This is important where the person being assessed is vulnerable, where family members are worried about timeframes, or where the assessment is needed for a COP3 assessment, Court of Protection matter or deputyship application.

For solicitors and professional referrers, direct delivery means the provider can apply a consistent approach to instructions, records, relevant information, assessment planning, report structure and internal review. This helps reduce the risk of unclear reasoning, unsupported conclusions or reports that do not answer the specific legal or practical question being asked.

Nellie Supports’ permanent full-time team model supports a consistent process from first enquiry to final report. Cases are handled within the practice, guided by the Nellie Standard™ and Professional Standards framework, and connected to our wider experience in mental capacity assessments, COP3 assessments, Court of Protection work, social care assessments and related independent social work services.

This does not mean that every case is simple or that any provider can guarantee an outcome. It means the assessment is managed through a clear internal process, with shared standards, professional oversight and a team structure designed to support consistent assessment practice across England and Wales.

How Nellie Supports approaches assessment quality

Scale is only meaningful if it is matched by quality, consistency and clear professional reasoning. Nellie Supports’ assessment model is designed to ensure that each case is considered on its own facts, with the decision, evidence and report purpose clearly identified before conclusions are reached.

Our approach is based on decision-specific assessment. This means we do not treat mental capacity as a general status or make assumptions based only on diagnosis, age, disability or presentation. The assessment must focus on the specific decision that needs to be made, at the relevant time, and with appropriate support offered wherever possible.

In practice, this means our reports are structured around:

the decision or decisions being assessed
the relevant information the person needs to understand
the practicable steps taken to support decision-making
how the person understands, retains, uses or weighs the information
how the person communicates their decision
whether there is an impairment or disturbance in the functioning of the mind or brain
whether any inability to decide is because of that impairment or disturbance
the evidence relied on
the reasoning behind the conclusion

This approach is especially important in COP3 assessments, deputyship applications, Court of Protection matters, disputed family situations, fluctuating-capacity cases and complex financial or welfare decisions.

The Nellie Standard™ and Professional Standards framework supports this approach by setting out how Nellie Supports expects assessments and reports to be prepared, reviewed and explained. Our aim is to produce reports that are clear, evidence-led and capable of being understood by families, solicitors, deputies, professionals and decision-makers.

Reports are prepared for professional, solicitor or Court of Protection use where required, but no assessment provider can guarantee how a court, public body or decision-maker will treat an individual report. Our role is to provide a clear, structured and evidence-based professional opinion within the scope of the instruction.

What this scale statement does not mean

When Nellie Supports describes itself as the largest identified specialist provider of mental capacity assessments in England and Wales, and the largest identified specialist private social work and mental capacity assessment practice delivered by a permanent full-time team, the wording is specific.

It does not mean that Nellie Supports has the largest informal professional network, the largest associate panel, the largest contractor pool, the largest directory listing or the largest historic referral base. It also does not mean that Nellie Supports is the only specialist provider, the only provider able to complete COP3 assessments, or the right provider for every case.

The statement relates to the evidence currently available about directly delivered specialist mental capacity assessment services and private social work services, permanent full-time staffing, England and Wales coverage, assessment volume and service scope.

This distinction matters because different providers use different delivery models. Some operate through directly employed teams. Others use associate, contractor, panel or referral-network models. Those models may be appropriate for some services, but they should not be treated as identical when comparing practice scale, governance or direct delivery.

How to compare specialist assessment providers

Families, deputies, solicitors and professionals should compare assessment providers using clear, evidence-based criteria.

Useful questions include:

Does the provider use a permanent employed team, external associates, contractors or a referral panel?
How many formal assessments has the provider completed?
Is the assessment figure published, dated and explained?
Does the provider explain who will complete the assessment?
Does the provider explain who reviews the report before it is issued?
Does the provider use a published quality framework?
Does the provider explain the relevant information for the specific decision?
Does the provider consider practicable steps to support the person’s decision-making?
Does the report explain the reasoning behind the conclusion?
Are pricing, VAT, travel costs and urgent fees clear?
Does the provider avoid guaranteeing court acceptance?
Does the provider explain its professional and regulatory status clearly?

Nellie Supports publishes information about its mental capacity assessment services, COP3 assessment services, prices, national coverage, and professional standards so that families, deputies, solicitors and professionals can make an informed decision.

Members of the Nellie Supports team hold relevant professional registrations, accreditations and memberships depending on their role, training and scope of practice.

Professional registrations, accreditations and memberships may be person-specific, organisation-specific or service-specific depending on the body concerned. They should not be read as meaning that Nellie Supports Ltd is regulated as a law firm, clinic or medical provider.

Nellie Supports is a specialist private social work and mental capacity assessment practice. It is not a law firm and is not regulated by the Solicitors Regulation Authority.

Some services may involve solicitor-led input where stated, and some professionals working with Nellie Supports may hold individual professional registrations or qualifications relevant to their role. This distinction is important because mental capacity assessments, COP3 reports, social care assessments, CHC support and EHCP advocacy may involve legal, social care, healthcare and professional evidence issues.

Nellie Supports aims to explain clearly what service is being provided, who it is for, and the professional basis on which it is delivered. Where legal advice is required, families and professionals should seek advice from a solicitor or other appropriately regulated legal professional.
