Evidence-led retrofit planning

Evidence-led retrofit planning

Evidence-led planning for sustainable retrofit at scale.

Ivynest helps retrofit professionals evaluate options, cut planning risk and make defensible retrofit decisions before delivery begins.

Because retrofit outcomes are largely determined long before installation starts.

Retrofit success starts early

Retrofit success starts early

The biggest retrofit decisions are made before delivery begins.

Risk is introduced earlier, during assessment, option selection and planning, when decisions are hard to compare and evidence is fragmented.

Once delivery begins, changes become slower, more expensive and harder to justify.

Ivynest strengthens the stage where retrofit outcomes are really decided.

Planning is where outcomes are shaped.

Where Ivynest fits

Most platforms support retrofit delivery.

01Planning

Evaluate options and define retrofit strategy

02Delivery

Coordinate installation and PAS2035 workflows

03Compliance & Verification

Track outcomes and reporting

Better decisions upstream reduce risk downstream and save time before project move into delivery.

Platform overview
Platform overview

One planning platform. Different retrofit needs.

Ivynest supports retrofit professionals from early option assessment through to programme planning at scale.

Planning

Ivynest Navigator

For companies defining what should be done, before delivery begins.

Navigator enables retrofit teams to evaluate improvement options, compare outcomes and understand performance, cost and risk implications early. Retrofit Coordinators gain structured optioneering. Programme leads gain confidence that recommended measures are consistent, transparent and defensible before progressing into delivery.

Transition

Ivynest Convert

For teams moving approved retrofit strategies into delivery.

Convert transforms agreed pathways into structured, PAS2035-aligned outputs, reducing manual preparation and ensuring decisions transition cleanly into delivery workflows. Built-in lead generation helps installers and delivery teams turn approved plans into actionable opportunities faster.

Scale

Ivynest Portfolio

For organisations planning retrofit investment across housing portfolios.

Portfolio enables teams to evaluate properties at scale, prioritise interventions and balance performance, funding and delivery risk across programmes. Supporting confident, evidence-led investment decisions.

Retrofit delivery does not begin on site.

It begins with decisions.

Ivynest provides the structure and evidence needed to make those decisions defensible, before delivery begins.
