Your guide to costs
A smarter investment in a warmer, healthier home – with honest guidance every step of the way.
At Cosy Homes Oxfordshire, we believe in clarity – so you can make confident decisions about your home. Many homeowners choose to begin with a Whole House Plan: a tailored roadmap showing which improvements will make the biggest difference, and in what order.
Once you’ve had your Whole House Plan, we can stay with you through the next stages. If you decide to move ahead, we offer two further support packages – a Technical Specification to set out the detail for contractors, and a Technical Support Package to guide the work on site. Both are optional, with clear pricing agreed in advance. No hidden costs, no pressure – just practical guidance to help you get the job done properly.
Whole House Plan
A Whole House Plan is a personalised roadmap created by a qualified Retrofit Coordinator. It shows you what to prioritise now, how to phase upgrades over time, and where to get the best value.
Typical cost: £600 for homes up to 4 bedrooms (incl. VAT).
Larger or more complex homes priced individually.
(We’ll talk it through with you first.)
“The Whole House Plan gave us a clear, structured view of our energy improvement options, including carbon impact. Excellent value for money – I’ve already recommended it!”

Technical specifications
If you decide to move ahead with improvements, we’ll help you finalise the detail. A Retrofit Assessor will visit again to check feasibility and create a clear Technical Specification for contractors – making sure everything runs smoothly from the start.
This stage also includes an updated project estimate and a follow-up call to answer your questions before moving forward.
Typical fees: From £600 for a single measure, and around £1,600 for a full home package (5+ key measures). All prices include VAT.
Technical support package
When the work begins, we stay with you. Your Retrofit Coordinator will manage key details like scheduling, site visits and handovers – ensuring quality, minimising disruption, and preventing costly mistakes. We’ll keep you informed throughout and provide a handover pack when everything’s complete.
The exact cost of installation support depends on the scope of work and the level of service you need – but we’ll agree a fixed price with you before anything begins.
Flexible finance
We know funding can sometimes be the biggest barrier. That’s why we’ve partnered with Scroll Finance to offer flexible loans designed specifically for energy-efficient home upgrades.
Whether you’re topping up your savings or funding a whole project, Scroll can provide tailored green home improvement loans from £1,000 to £500,000.
It’s simply another way to make your plan achievable – helping you move forward in a way that fits your budget and timescales.
