June 2022 will see the latest updates to the Building Regulations, as part of the government’s effort to drive energy efficiency and reduce CO2 emissions. This will impact on new homes in England, that will have to produce around 30% less CO2 than current standards, with emissions from new non-domestic buildings, including offices and shops, reduced by 27%.
Alongside amendments to the Building Regulations, there are also a raft of updates to Approved Document L (covering energy efficiency), Approved Document F (covering ventilation), plus the addition of a new document, Approved Document O (covering overheating), changing how heating and ventilation are specified in both new and existing homes.
The major changes to the regulations include;
- Part L requirement for TRVs to be installed on radiators when a boiler is replaced, providing additional efficiency for the homeowner.
- The requirement under Part L to carry out a heat loss calculation for the property to ensure that the new or replacement boiler is not significantly oversized, again an ongoing benefit for the homeowner and environment.
- Maximum flow temperature for new and replacement heating systems should not exceed 55°C under the new Part L.
