About Us

Charlotte Cornish and Anna Grey are strategic research and evaluation consultants with more than 25 years of practising market and social research for public, private and third sector organisations.

In 2015, they established Cornish and Grey, a social enterprise providing evaluation and impact strategy support to social purpose organisations.

They work with funders, grant makers, capacity builders, umbrella organisations, charities and social enterprises to help develop simple and practical impact or measurement strategies so they can become more effective and ensure that limited funds are spent where they make the most difference.

Some Of Our Clients


In 2019 and 2020 we have delivered a number of projects for Wellcome’s Public Engagement team – most recently, qualitative research with key stakeholders to inform the development of Wellcome’s support to help potential grant holders articulate the difference their public engagement activities will make and an evaluation of a project to improve the health of night workers.


In 2017, we conducted an evaluation of the impact of including dementia in the over 45 health check for NHS England and now work with a range of clients across the NHS helping them develop different initiatives.


Pilotlight is a social enterprise that provides strategic business support to small local charities that help disadvantaged people. We have developed Pilotlight’s current monitoring and evaluation strategy and data collection tools and provide ongoing support, guidance and training to its project managers.

See Pilotlight’s impact report 2020.

The Communication Trust

We delivered individual programmes of support to seven of The Communiciation Trust’s (TCT’s) members. This involved a workshop followed by a written action plan, and a six month period of email/telephone follow-up support. We used our experience from delivering this programme to write a guide to self-evaluation on behalf of TCT for small organisations delivering speech, language and communication services for children and young people.

C&A Foundation

We were the independent impact evaluators of the C&A Foundation’s annual international ‘Inspiring Women’ campaigns 2015-2017 and ‘Inspiring World’ campaigns 2018-2019. We developed the evaluation strategy and conducted pre and post survey research and follow up focus groups in a number of different countries including China, Brazil, Mexico and across Europe.

Garfield Weston

In partnership with the Centre for Philanthropy at the University of Kent, we conducted a preliminary evaluation of the Weston Charity Awards to help the trustees of the Garfield Weston Foundation decide whether and how to roll out the programme


Since December 2016 we have been helping Pause develop evidence of their impact for media coverage (see Guardian Society article: Mother Courage – swapping pregnancy in exchange for help Louise Tickle 25th January 2017) and for the first Pause Celebration Event. We are providing ongoing support to help scope the need for their offer in new areas alongside self-evaluation of their existing programme.

Social Venture Partners London

SVP is an umbrella organisation, founded in America, which encourages and facilitates philanthropists to make a difference. We have provided guidance to both Social Venture Partners London and Social Venture Partners Singapore for thinking about their impact strategy.

Dementia Adventure

We have been appointed as Dementia Adventure’s Evaluation Partner on their three year programme (2020-23) of ‘Thinking Differently about Dementia’ support events for informal (unpaid) carers looking after somebody with dementia. The programme was initially planned as a mix of face to face and webinar events and we are supporting the team to use activity monitoring and feedback data to learn and improve as they adapt their services to work in the context of COVID.

Alzheimer’s Society and Alzheimer’s Research UK

In partnership with Solutions, a qualitative research company, we evaluated the impact of the inclusion of dementia in the 40-64 year old NHS Health Check (funded by Public Health England). This involved an experimental design with research sample and control sample counterfactual.

Wheels for Wellbeing

We advised Wheels for Wellbeing on the development of in-house data collection tools and provided the analysis and reporting for ‘Wheels for Change’, a three year programme funded by Comic Relief.

The Sunnybank Trust

As a consultant on the Lloyds Bank Foundation Enhance programme, Anna supported The Sunnybank Trust – a charity working with adults with learning disabilities - to develop and implement a revised Evaluation Strategy.

The impact of volunteering

If an organisation uses volunteers, it is just as important to gather feedback from them as it is to gather feedback from those recognised as the ‘service users’. Our evaluation work for Pilotlight, for example, has demonstrated that there are many similarities between the change experienced by those delivering the support (business leaders) and those receiving the support (charity leaders).

How does a capacity building organisation measure success?

The starting point for measuring success for a capacity building organisation is the same as it is for a frontline service organisation - understanding the difference it is trying to make. In this blog for Pilotlight, Anna summarises how tracking activity and gathering feedback from stakeholders has helped identify the set of indicators currently used to measure change for charities supported through the Pilotlight Programme.

Which tool for measuring wellbeing?

We often get asked what is the best tool for measuring wellbeing. In this blog for Trajectory, Charlotte signposts some places to start.

Looking for Change in the Right Place

We have delivered annual workshops for Pilotlight’s business volunteers to build their understanding of measurement in the charity sector and improve their effectiveness in supporting the charities they are partnered with. Pilotlight project manager, Hannah, summarised the learning from one of these events in a subsequent blog.

Building an approach to self evaluation

In 2016, we wrote a guide for The Communication Trust on: ‘Building an approach to self evaluation’. This is aimed at small voluntary and community sector organisations delivering children’s speech, language and communication services and can be downloaded from the Trust’s new ‘developing and using evidence’ page

Good Science, Bad Governance

Anna’s extensive work with second tier membership organisations has given her particular insight into the challenges facing small and medium sized charities with measurement.  In this guest blog for the Communication Trust she argues that a ‘good governance’ approach to evidence is more appropriate for small voluntary and community sector organisations than a ‘good science’ approach.

Take control of your impact

During training sessions, Pilotlight project managers often report to us that the charities they are supporting are reluctant to identify key outcome measures for fear that they will no longer match the requirements of a particular funder. Anna addresses this issue in a guest blog for Pilotlight.

The Language of Measurement

Pilotlight’s business volunteers often think social impact measurement is something specific to the third sector and beyond their skills set.   Charities tend to think that market research has no relevance to them and their stakeholders since they are not in the business of ‘selling’.  The reality is that social impact measurement, like market research, is a core part of the strategic planning process.  We see our work with Pilotlight as helping the two sectors to speak the same language.

What is qualitative research and how should charities use it?

The value of qualitative research is often overlooked or misunderstood by the charity sector.  Yet qualitative methods, which aim to provide a deeper understanding of the values, attitudes, motivations and behaviours of individuals and target groups, can be essential in helping to understand the impact of their services.
