PAS 2035 Retrofit Coordination

PAS 2035 is the British standard for domestic energy efficiency retrofit. It was introduced by the government in 2019 to address the problem of botched retrofit work — insulation installed incorrectly, ventilation ignored, resulting in damp and mould. PAS 2035 mandates a "whole house" approach with a qualified Retrofit Coordinator overseeing the project from assessment through to completion. If your project receives government funding (ECO, SHDF, LAD, HUG) or is registered with TrustMark, PAS 2035 compliance is mandatory. Even for self-funded projects, PAS 2035 principles represent best practice.

A PAS 2035 Retrofit Coordinator must hold a Level 5 Diploma in Retrofit Coordination and Risk Management and be registered with a TrustMark-registered scheme provider. The qualification covers building physics, moisture risk assessment, construction technology, heritage considerations and project management. Our coordinators are fully qualified and experienced in coordinating domestic retrofit projects across a wide range of property types and ages.

PAS 2035 compliance is mandatory for all projects receiving government funding for domestic energy efficiency measures. The main schemes are: ECO (Energy Company Obligation) which funds insulation and heating measures for fuel-poor and vulnerable households; SHDF (Social Housing Decarbonisation Fund) which upgrades social housing stock; LAD (Local Authority Delivery) which provides energy efficiency upgrades for low-income households; and HUG (Home Upgrade Grant) which funds whole-house retrofit for off-gas-grid properties. If your project is funded by any of these schemes — or by a local authority or housing association — you will need PAS 2035 compliant coordination.

A medium-term retrofit plan is a central requirement of PAS 2035. It is a document that sets out a logical, sequenced pathway of energy efficiency measures for a property, typically over a 20 to 30 year period. The plan considers the interaction between different measures — for example, ensuring that insulation is paired with adequate ventilation to avoid moisture problems. Each measure is assessed for its impact on building physics, cost-effectiveness and practical delivery. The plan allows homeowners, landlords and social housing providers to phase improvements over time without compromising the overall integrity of the building.

The cost of PAS 2035 retrofit coordination depends on the number of properties, the scope of the retrofit measures and the complexity of the project. Single-property coordination typically starts from £500 plus VAT. For multi-property programmes — such as social housing schemes — we offer volume-based pricing. Every project receives a fixed-price quote within 24 hours of enquiry. Contact us with the details of your project and we will provide a clear, all-inclusive price with no hidden extras.

Yes. We provide PAS 2035 retrofit coordination across our full coverage area: Bedfordshire, Buckinghamshire, Cambridgeshire, Hertfordshire, Northamptonshire, Greater London and Oxfordshire. Our Retrofit Coordinators are locally based and familiar with the building stock, construction types and common defects in each county. We also understand the local authority and housing association landscape, which is particularly relevant for SHDF and LAD-funded programmes. If your project falls outside our core area, please enquire — we may still be able to help.
