The problem we solve

Retrofit at scale is genuinely hard. We’ve engineered the hard parts so you don’t have to.

Coordinating surveys, measure design, installation, tenant liaison, compliance documentation and grant reporting across hundreds — or thousands — of mixed-archetype properties is more complex than most contractors are willing to admit until they’re already failing at it. Programmes stall in the design phase. Lodgements miss deadlines. Tenants complain to councillors. Subcontractor chains collapse and the post-installation EPC evidence never quite matches the property file. Audit trails turn out to have gaps the paperwork didn’t show.

We’ve built the operating model — and the team — to handle this properly. A single named project manager from contract award to final certification. Live programme tracking visible to your team. A tenant-engagement pathway designed with vulnerable households in mind. A documentation package that has, to date, been audited dozens of times and failed zero. And a culture of openly raising risks early, so issues are surfaced and resolved before they reach your inbox.

We don’t win public-sector contracts by being the cheapest. We win them — and we keep them — by being the contractor that doesn’t need supervising. By delivering on the promised plan, on the promised date, with a handover pack that makes your compliance officer’s job genuinely easy.

Our offer

Everything you need. None of what you don’t.

Full Programme Management

Survey to handover. One team. One contact.

We manage every stage of the programme in-house — initial assessments, retrofit assessments under PAS 2035, measure design, installation scheduling, tenant liaison, post-installation testing, lodgement and final handover. You get one named project manager who knows your programme by heart and is reachable throughout. No subcontractor daisy-chain. No misaligned timelines. No “that’s not us, that’s the supplier” calls.

For larger contracts you also get a live programme dashboard — actual properties surveyed, designed, installed, lodged, signed off — updated in near real time and accessible to your team without a portal request or a six-week dev cycle.

Compliance-Ready Delivery

PAS 2030 and PAS 2035-aligned. Audit-strong. Documentation-perfect.

Our delivery is fully aligned with PAS 2035 — the whole-house retrofit framework that governs assessment, design and installation sequence — and certified to PAS 2030:2023 for installation quality. Every property generates a complete documentation package: TrustMark lodgement data, retrofit assessment and design sign-off, post-installation EPC evidence, monitoring data where applicable, manufacturer commissioning records, and a quality-assurance report per measure per property.

We maintain certification across multiple bodies (BSI / British Assessment Bureau, Installation Assurance Authority, Qualitymark Protection) so whichever framework or grant scheme your programme runs under, we’re already certified to operate within it. Your stage-gate submissions go in clean.

Tenant-First Approach

Minimal disruption. Plain-English communication. Sub-1% complaint rate.

Tenants didn’t choose to have their home retrofitted. We treat that fact with the seriousness it deserves. Our tenant liaison process starts before the first survey letter goes out — and continues for thirty days after the final measure is signed off. Plain English ahead of every visit, accessible-format communication on request, respect for access preferences, and a satisfaction call after every property completion.

Across all our public-sector programmes our complaint rate runs consistently below one per cent of tenants — and complaints that do arise are typically resolved inside seven working days.

Our survey methodology

The right discipline for the right measure on the right property — every time.

Programme-scale retrofit only works when each individual property is properly understood. We bring the same survey discipline to a 500-home programme that we bring to a single private home — sequenced and resourced to work at scale.

Thermal imaging
On every fabric and ventilation assessment — the most efficient way to identify heat loss, cold bridges and existing insulation failures across a portfolio consistently.
Borescope cavity inspections
On every property considered for cavity wall insulation, without exception. This is the single biggest reason cavity programmes fail, and we don’t skip it.
LiDAR scanning + EN 12831 modelling
For any property considered for an air source heat pump — sized to the actual building, room by room.
Drone aerial surveys + photogrammetry
For any property considered for solar PV — accurate roof geometry, shading patterns and structural assessment without scaffolding.
Practical heating-system inspection
System pressure, balancing, controls and condition — for any boiler or central-heating scope.
PAS 2035 retrofit assessment & coordination
Wrapping all of the above into a coherent whole-house plan, with sequenced measure recommendations and ventilation strategy.

The result is a property file per address that holds up to audit, a measure-by-measure recommendation that’s right for the building, and a programme schedule that’s deliverable.

Programmes like yours, completed.

Numbers below are actual outcomes from delivered programmes — not modelled estimates, not pitch-deck projections.

Sector

Property type

Detached, 1970s · Homeowner

Four-Bed Detached — Full Retrofit, Surrey

Air source heat pump · Solar PV (6 kW) · Battery storage · Loft insulation · Cavity wall insulation

Annual saving: £1,240

EPC: E (44) → B (89)

“We budgeted for disruption and got almost none. Three actual days of work, spread across two weeks to suit our diary. The house is warmer than it has ever been and the first winter bills were a genuine shock — in the good direction.”

Read the case study

Victorian mid-terrace, solid walls · Homeowner

Victorian Terrace — Boiler & Internal Wall Insulation, Sheffield

High-efficiency condensing boiler · Internal wall insulation (2 rooms) · Loft insulation top-up

Annual saving: £680

EPC: F (28) → D (62)

“They were upfront that solid-walled Victorian terraces are never easy to insulate. They explained the trade-offs in language I could actually follow, we chose internal insulation for the two coldest rooms, and the difference is remarkable. Rooms we barely used are now comfortable in January.”

Read the case study

Mixed — 1960s council flats and terraces · Social Housing

Council Housing Programme — 60 Properties, West Midlands

Solar PV · External wall insulation · Loft insulation · Heating controls upgrade

Annual saving: £620 per property

EPC: D average → B average (94% of properties)

“The documentation package was the best we have had from any installer. Every property had its own compliance file, every TrustMark lodgement completed within forty-eight hours. It made our grant reporting genuinely simple.”

Sheltered housing, older residents · Social Housing

Sheltered Housing Programme — 25 Units, Yorkshire

New heating systems · Loft insulation · Draught-proofing · Heating controls

Annual saving: £480 per unit per year

“Working with vulnerable tenants demands patience and real sensitivity. Smart Energie's team understood that instinctively. Not a single complaint from residents across the whole programme — something we have never said about a retrofit before.”

Programme partners

What programme leaders say.

“I was nervous about the whole thing. We'd had a bad experience with another company who left us with a faulty boiler and stopped answering the phone the moment we mentioned it. Smart Energie were a different planet. The engineer talked me through everything before he started. The quote matched the final invoice to the penny. He cleaned up better than we do. Our bills dropped noticeably in the first month — and when we had a question about the controls six weeks later, the same engineer rang me back the same afternoon.”

Working together

From first conversation to programme launch.

Initial Conversation

A 30-minute call with our partnerships lead. We learn your programme scope, property archetypes, timescales, funding streams and any existing framework requirements. You learn how we work, what our current capacity looks like, and what we’re realistically prepared to take on. We’re honest about both.

Proposal & Evidence Pack

A written proposal tailored to your specific programme — methodology, comparable case studies, mobilisation plan, indicative pricing, plus a full credentials pack covering accreditations, insurance, references, financial standing, modern slavery, sustainability and social value. Not generic tender boilerplate. A document written for your scheme, by humans who’ve read your brief properly.

Programme Design & Mobilisation

For accepted programmes we assign a dedicated project manager, run a joint programme design workshop, and agree a reporting cadence and escalation pathway. We share a delivery schedule that you can challenge, and we publish progress against it from week one. Your team has full visibility throughout.

Let’s talk
