How our retrofit service for homeowners works

The Cosy Homes Oxfordshire service centres on a whole house approach to home retrofit, providing a full, one-stop-shop service for homeowners who want to increase the energy efficiency of our homes. Once you register your home you will be assigned an expert Retrofit Coordinator based on your needs, who will act as your single point of contact throughout – through there will likely be other Coordinators involved behind the scenes depending on the expertise needed for your specific home.

On this page we’ll explain how the service works and the different stages involved. We’ll also explain where costs come into the service, and the different routes that you can take to get started on your home retrofit with us.

Step 1: home assessment

The first step is for one of our Retrofit Assessors (or sometimes a Retrofit Coordinator, depending on availability) will come and assess your whole house to find out everything we need to know about your existing energy usage and the building itself.

Find out what to expect from a home assessment by watching the short video to the right of your screen, or read our blog: What can you expect from a home assessment?

Step 2: Whole House Plan

Your Retrofit Coordinator will then use this information to develop a bespoke Whole House Plan for your home, detailing all the measures you could take to make your home as energy efficient as possible as a whole, with recommendations on the most cost-effective and impactful measures to take forward, and in which order.

It’s then up to you to choose which measures you go ahead with, with the support and advice of your Retrofit Coordinator. If you do decide to go ahead, your Retrofit Coordinator will also manage the delivery of the work, finding trusted contractors, managing health and safety onsite, and checking the quality of delivery once complete. You can see all the steps of the retrofit process in the diagram below.

The full process

What costs are involved?

Our home assessment and Whole House Plan service costs £175. This covers the cost of the time needed to assess your home, as well as the time spent by your Retrofit Coordinator on analysing the information gathered at your home assessment and creating your detailed, bespoke Whole House Plan.

The Whole House Plan will give you an idea of the costs of different retrofit measures should you choose to go ahead with the work recommended, but please be aware that the cost of a whole house retrofit can vary greatly based on the type of home that you live in and the measures which you decide to implement.

If you choose to go ahead with some or all of the measures outlined in your Whole House Plan through Cosy Homes Oxfordshire, there will be a 5% project charge for the service. This covers the cost of a Retrofit Coordinator to look after your home and act as your single point of contact from start to finish –gathering quotes from contractors, managing work and installations, and checking the quality of delivery once completed. And the peace of mind you gain from that? It’s priceless.

Please note: there will likely be additional costs between the Whole House Plan and the project work beginning, depending on the size and type of your retrofit project and the measures included. This includes any Technical Specialist Reports and Building Performance Specifications required by your project – and will be detailed in a Client Service Agreement sent to you before the project goes ahead, which your Retrofit Coordinator will be able to discuss with you.

How to get started

There are three routes to get started with your home retrofit, depending on your needs and the direction you’d like to take.

Cosy Homes Oxfordshire Plan Builder (free)

If you’re curious about the current energy performance of your home but not quite ready to commit to starting your home retrofit process, we’d recommend checking out our free Plan Builder.

Simply put your postcode into the online tool and it will tell you everything you need to know about the current energy performance of your home. The planner will also suggest several measures which you could take to improve energy efficiency. If you’d like to explore these measures, we’d recommend you then register your home with us for a bespoke assessment and Whole House Plan.

Remote Assessment and Pre-Visit Whole House Plan (£75)

When you register your home you’ll be asked if you’d like a remote or onsite assessment. If you choose remote, we’ll use existing data sources such as EPC data, Google Maps, or floorplans to find out as much as we can about your home. One of our Retrofit Coordinators will then conduct a 1 hour phone assessment with you, asking you a series of simple questions about your home to fill in any gaps. With this information they’ll produce a reduced version of our Whole House Plan, detailing the recommended measures to improve energy efficiency.

If you choose to go ahead with any or all of the measures, you’d be required have an on-site assessment to ensure nothing has been missed, paying the balance of £100.

Full Onsite Assessment and Whole House Plan (£175)

If you choose an onsite assessment when registering, one of our trained Retrofit Coordinators will contact you to book a time for your onsite home assessment, which can take up to 3 hours.

We’ll use the information gathered to produce a bespoke Whole House Plan, detailing the recommended measures to improve energy efficiency. This will include any particular needs we’ve already discussed with you.
