About The National Energy Foundation (NEF)

The National Energy Foundation (NEF) is an independent charity based in Milton Keynes, which has been at the forefront of improving the use of energy in buildings since 1988. We aim to give people, organisations and government the knowledge, support and inspiration they need to understand, manage and reduce the use of energy in buildings.

NEF operates a hybrid working policy, which means that employees can work, remotely, from home (within the UK) on four out of five days. On the fifth day, employees are expected to work from NEF’s offices in Milton Keynes.

All roles within NEF start with an induction process and a six-month probation period.

SuperHomes & Energy advice project

SuperHomes is a project delivered by NEF which has a focus on whole house domestic retrofit. It is both a Network of Members and a Rating Scheme for private sector housing. All customers are encouraged to follow a retrofit journey that is aligned to PAS2035 (Retrofitting dwellings for improved energy efficiency), starting with a Whole House Retrofit Plan (WHRP) – also known as a medium-term improvement plan – produced by a Retrofit Coordinator.

Due to our recent success in securing new funding for a local demonstration project, NEF are looking to recruit two Retrofit Assessors to support our existing Retrofit Coordinators in the delivery of a significant number of free retrofit option appraisals. The appraisals will act as initial advice to homeowners as to how they could improve domestic energy efficiency. The appraisals will follow a new template and will essentially be a slimmed down version of a full medium-term improvement plan, which could later be developed into a full retrofit PAS 2035 plan if required. The slimmed down version is referred to herein as a ‘lite’ plan.

The project will be focused in two counties, Hertfordshire and Bedfordshire, but may in future be expanded to other regions in the UK.

Role Summary 

The Retrofit Assessors will each work closely with and support an existing inhouse Retrofit Coordinator to deliver a high volume of ‘lite’ retrofit plans. The Assessors will carry out the majority of the home surveys, input data into SAP energy modelling, populate the ‘lite’ plan template including making recommendations on retrofit options. The Coordinator will be responsible for checking and quality assuring the ‘lite’ plans before they are issued to customers.

You will also provide technical advice and guidance to customers and members of NEF staff. This will from time to time include online and in person events where you will represent NEF.

Candidates applying for this role must be both an accredited Retrofit Assessor (level 4) and Domestic Energy Assessor (DEA).
