Insight on retrofit, energy, policy and net zero construction from across the practice.
From 24 March 2027, gas boilers will not be a viable heating option for new homes in England. The Future Homes Standard contains no explicit ban, but it sets performance targets that a gas boiler cannot meet regardless of how well insulated the building is. If you are developing, designing, or advising on new residential schemes, this affects your programme and your specification now.

An air pressure test is one of the last formal compliance checks before a dwelling can be signed off. On most developments it is treated as a formality, and on too many that assumption proves costly.

If you work with new homes, existing housing stock or modelled energy performance, you are going to hear a lot more about the Home Energy Model, or HEM. It is the government calculation methodology that will replace the Standard Assessment Procedure (SAP), and it will change how homes are assessed for both Building Regulations compliance and Energy Performance Certificates (EPCs). Here is what is changing, when, and what we think you should be doing about it.

Stranding risk is the risk that a building becomes difficult to let, finance or sell before the end of its expected life because its energy and carbon performance falls behind what regulation, investors and occupiers require. It shows up in commercial terms, through rent, yield, capital expenditure and credit terms, rather than as a technical measure alone.

As building fabric standards improve, the way we think about heat loss, and about where surfaces run cold, is changing. As we reduce heat loss through the main building elements, junction heat losses become proportionally more important.

As of August 2026, Develeco are accredited NABERS UK Energy for Offices Assessors. NABERS UK rates commercial buildings on their actual, in-use energy performance, measured from real metered data, rather than on design stage assumptions.

The government intends to launch a reformed domestic EPC from October 2026, replacing the single A to G rating with four headline metrics. It has also confirmed that landlords in England and Wales will need to bring private rented homes up to EPC Band C by 1 October 2030.

The government has confirmed EPC Band B by 2031 for non-domestic buildings over 1,000m², where cost effective, and dropped the proposed EPC C by 2027 milestone. How the 1,000m² threshold applies to multi-let buildings is still undecided.

A net zero energy audit goes beyond a standard assessment to set out a credible, costed pathway to a net zero building.

Moisture risk is one of the most important, and most overlooked, considerations in any retrofit project.

PAS 2035 is the overarching framework for domestic retrofit, and the role of the Retrofit Coordinator is central to it.

Retrofit means upgrading existing buildings to improve energy performance, comfort and carbon, at the scale the UK's stock demands.

Tackling climate impact in construction means addressing both the carbon a building emits in use and the carbon locked into its materials.
