Who We Help

Retrofit services for homeowners, landlords, housing providers, architects and contractors across London.

Homeowners

Most homeowners come to us before spending money on insulation, windows or a heat pump, or after something has not worked as expected. We help you understand the house first, then plan improvements in a sensible order.

What usually matters

  • Impartial advice independent of any installer
  • Understanding what suits an older or listed home
  • Avoiding damp, mould and draught problems
  • Phasing work to fit budget and life

Landlords and property managers

Landlords need information that stands up for each property and across a portfolio – whether planning ahead for energy-efficiency regulation, responding to damp and mould complaints, or improving homes between tenancies.

What usually matters

  • Consistent information across several properties
  • Access arrangements with tenants
  • Clear documentation for records
  • Prioritising properties and measures

Housing providers

Social landlords, housing associations and local authorities often deliver retrofit through funding programmes that require PAS 2035:2023. Programmes such as Warm Homes: Social Housing Fund and ECO4 require PAS 2035 compliance; each has its own documentation rules.

What usually matters

  • PAS 2035 assessment and coordination
  • Batch planning across house types
  • Resident communication and access
  • Records suitable for scheme requirements

Architects and designers

Architects working on existing buildings sometimes need specialist retrofit input on a specific question – a junction’s condensation risk, heat loss for system sizing, or an airtightness baseline – without handing over the whole project.

What usually matters

  • Clear, documented technical outputs
  • Scoped input on defined questions
  • Early identification of moisture and ventilation risks
  • Information that integrates with your drawings

Contractors and installers

Contractors delivering funded or specified work may need an independent assessor, coordinator or designer, or test results that evidence the quality of the work.

What usually matters

  • Independent roles where schemes require them
  • Clear design information to price and build against
  • Pre- and post-works testing
  • Prompt, practical answers to site queries
