PAS 2035 · Elmhurst-accredited

Retrofit Assessments in the Tees Valley

The formal whole-dwelling survey that unlocks grant-funded improvements — carried out by our in-house, Elmhurst-accredited retrofit assessor. £229, across Middlesbrough, Stockton, Hartlepool, Redcar & Cleveland and Darlington.

Why retrofit assessments matter right now

The government's Warm Homes Plan is putting roughly £15 billion into home energy upgrades by 2030, delivered locally through councils and housing associations, with grants of up to £30,000 per property. Every funded project has the same first step: a PAS 2035-compliant retrofit assessment. No assessment, no funding.

And the Tees Valley is exactly where that money needs to land: around half the region's homes sit below EPC C — we know, because we analyse all 238,000 of them.

What the assessment covers

  • Full energy assessment of the dwelling
  • Building condition — damp, defects, structure
  • Ventilation assessment — the part naive retrofits get wrong
  • Occupancy assessment — how the home is actually used
  • Clean documentation, ready for your retrofit coordinator

£229 per dwelling — done properly, not to a stopwatch

Retrofit assessments, explained

What is a PAS 2035 retrofit assessment?

It's the formal whole-dwelling survey that must happen before grant-funded energy improvements can start. Unlike a standard EPC, it looks at the building's condition (damp, structure, defects), its ventilation, and how the home is actually occupied — as well as its energy performance. The output is a proper foundation for retrofit design, so measures get specified for the house as it really is.

How is it different from an EPC or your Retrofit Roadmap?

An EPC (£65–£99) is the standard energy certificate you need to sell or let. Our Retrofit Roadmap (£169) adds a costed, prioritised improvement plan — right for owners improving at their own pace. A PAS 2035 Retrofit Assessment (£229) is the formal survey required for publicly funded work, and the most thorough of the three. If you're aiming for grant funding, this is the one you need.

Do I need one to get a Warm Homes grant?

Yes. The Warm Homes Plan — the government's ~£15bn programme running to 2030, delivered through councils and housing associations with grants of up to £30,000 per property — requires a PAS 2035-compliant retrofit assessment before funded work can proceed. No assessment, no funding.

Who carries out the assessment?

Our in-house assessor, accredited as a Retrofit Assessor with Elmhurst Energy — the UK's largest accreditation scheme. Local, experienced in exactly this housing stock, and backed by our analysis of every home in the Tees Valley.

I'm a retrofit coordinator or installer — can you supply assessments?

Yes. We offer assessment capacity to coordinators and installers working funded schemes across the Tees Valley and surrounds — fast turnaround, volume rates, and clean documentation your projects can rely on. Email hello@northyield.co.uk or use the form below and we'll talk numbers.

Which areas do you cover?

Middlesbrough, Stockton-on-Tees, Redcar & Cleveland, Hartlepool and Darlington, with surrounding areas by arrangement.
