The UK is about to embark on a retrofit revolution that will shape how tenants feel about their homes and landlords for generations. BTP Architects’ Josh Pearson explains how the sector can set itself up to succeed.

After years of policy ambition and pilot schemes, the retrofit focus is shifting to large-scale implementation, with billions invested in bringing homes up to modern standards. However, this opportunity also presents a clear challenge: to strengthen the public’s fragile confidence in retrofit.

We have seen too many retrofit schemes where residents experienced disruption, poor workmanship or unclear benefits, with homes being repaired or upgraded only to require follow-up works shortly after. When assessing retrofit remediation works, we often find residents are not on board due to previous poor experiences, and an overwhelming lack of faith that delivery partners will get it right this time.

So, how do you reassure residents that this time it will be different, and they won’t be doing this all over again in a few months?

For residents, retrofit success is measured in simple, tangible terms. Does the home feel warmer? Has damp and condensation gone? And just as importantly, did the process feel respectful and well-managed?

These outcomes are not always visible the day scaffolding comes down. It can take months of heating bills and seasonal change to show results. That makes quality assurance, monitoring and aftercare essential, not only to evidence performance, but to reassure residents that promised improvements are being delivered.

Be prepared

One persistent misconception around retrofit is that programmes can be delivered through a standardised works package. But every home is different.

Variations in construction, alterations, ventilation and occupancy mean careful assessment is essential. When surveys or inspections are rushed, incorrect assumptions lead to delays, rework and rising costs. Visible uncertainty quickly undermines confidence in delivery partners and programme outcomes.

Damp ingress, leaking gutters, poor pointing, drainage issues and ventilation deficiencies all need remediation before insulation or airtightness improvements. If these are missed, residents are left rueing the consequences.

In light of Awaab’s Law, ventilation, especially, must be treated as a core measure and not an optional add on. Getting this right is fundamental to any successful retrofit scheme.

Quality and proof

Retrofit delivery that residents can trust is about more than installation quality. It requires coordination, sequencing and evidence management. Improvements must be delivered in the correct order and documented accurately, otherwise performance suffers, snagging increases and funding can be jeopardised.

Quality control should run throughout delivery — not just at practical completion. By conducting regular inspections, implementing clear standards and collecting time-stamped photographic evidence, teams can reduce abortive works and help ensure a consistent outcome. This creates the proof residents, regulators and landlords expect: a clear record of what was installed, why it was chosen and how performance and safety risks were managed.

On a recent scheme in St Helens, once the contractor was appointed, we organised a meeting with the installation team to review the design documentation, address buildability queries early and ensure the team clearly understood the evidence required.

We also arranged for a pilot property to be completed at the outset. This provided a benchmark for quality, ensured consistent installation standard and confirmed that the documentation being collated was suitable for TrustMark lodgement.

Putting robust processes in place early reduced the risk of delays and ensured smooth, efficient delivery on site for everyone — not least residents.

Communication is always key

Delivering retrofit in occupied homes introduces some practical challenges. Residents may work shifts, decline access, require safeguarding considerations, or need additional support. When not properly planned for, these realities can extend programmes and place pressure on delivery targets, increasing frustration for everyone.

Many access challenges can be mitigated through a productive lead-in period. Early communication, letter-drops and clear scheduling can help to build trust and improve cooperation.

Retrofit can also be more intrusive than expected, with scaffolding, noise, dust, repeated visits and heating disruptions, so consistent communication and a clear outline of expectations is essential.

Even a technically successful retrofit can be a failure if residents do not understand new systems or if snagging lingers for months.

Clear handovers, resident-friendly guidance and responsive aftercare help people realise the benefits of the work and mitigate some of the inconvenience experienced. A simple follow-up call, combined with clear routes to report issues, can be the difference between a resident recommending retrofit to neighbours or warning them against it.

One poor experience can undermine confidence across an entire street. High standards must therefore be maintained across every property.

Resetting relations

The current wave of investment represents a major opportunity for the sector to rebuild public trust in retrofit. But trust will only be rebuilt through teams who live organisational values, implement transparent processes and deliver consistency.

We have a chance to show that, when done properly, retrofit improves residents’ lives. Let’s take it.
