Energy efficiency is an important planning issue for Hertfordshire landlords, but the legal position needs careful wording. The government has confirmed its policy direction for a higher private rental standard by 1 October 2030, while the detailed regulations and reformed EPC methodology still require implementation.
September 2026 is therefore a useful point to review each property, not a reason to describe every proposal as law today. Homes across Hitchin, Letchworth Garden City, Baldock, Royston, Hatfield, Welwyn Garden City and other local markets vary in age, construction and heating, so one upgrade plan cannot fit every address.
What the 2030 policy currently says
The January 2026 government response says private landlords should meet the higher standard for all tenancies by 1 October 2030. The future test is intended to combine a fabric performance standard with either a smart-readiness or heating-system standard under the reformed EPC framework.
That is more precise than saying every home will simply need a particular score on today’s Energy Efficiency Rating. The response also provides transitional recognition for homes achieving EPC C or above under the current rating before 1 October 2029, subject to the certificate remaining valid or being replaced.
The legislative changes remain subject to Parliamentary approval, with updated regulations intended to take effect in 2027. Landlords should plan around the confirmed direction while checking the final law and guidance before treating a proposed detail as an enforceable current duty.
Keep current requirements separate
Existing minimum energy efficiency rules continue in the meantime. Privately rented homes generally require at least EPC E unless a valid exemption applies, and the landlord must provide the EPC information required for the tenancy.
Safety, repair, deposit, licensing and tenancy duties continue independently. A long-term energy plan does not replace current certificates, inspections or repairs, and an EPC recommendation does not by itself prove that a measure is suitable for the building.
Start with accurate property records
Find the current certificate on the official EPC register and record its rating, expiry date and recommendations. Note relevant work completed since the assessment, including insulation, glazing, heating and controls, together with invoices and guarantees.
If the certificate is old or no longer reflects the property, speak to an accredited assessor. Ask for advice that distinguishes today’s legal minimum from the planned 2030 framework, and retain the evidence with the property’s compliance record.
Turn the review into a portfolio plan
For more than one property, create a schedule showing EPC expiry, current rating, construction, heating type, known defects and likely tenancy access windows. Rank actions by legal urgency, building condition and the amount of technical uncertainty rather than simply starting with the lowest rating.
Review the schedule at least annually and whenever a certificate, tenancy or major component changes. This allows routine roof, window or heating work to be considered alongside energy performance before a specification or contract is agreed.
Assess the building before choosing work
Hertfordshire rental stock includes period terraces, solid-wall cottages, post-war houses, converted buildings and modern developments. Heat loss, ventilation, moisture, planning constraints and the condition of existing elements can change the appropriate sequence of work.
Repair defects before covering or enclosing parts of the building. Obtain competent advice before solid-wall insulation, major glazing changes or a new heating system, especially where the property is listed, traditionally constructed or within a conservation area.
Build a sensible improvement sequence
Fabric and ventilation
Loft insulation, draught reduction and suitable wall or floor measures may reduce heat loss, but the design must protect ventilation and moisture movement. Windows may sometimes be repaired, draught proofed or supplemented with secondary glazing rather than replaced.
Heating, controls and hot water
Review the heating system alongside the fabric plan. Controls, radiator valves, hot-water insulation and system efficiency can contribute, while heat-pump suitability depends on heat loss, emitters, space and design quality.
Access and tenancy timing
Plan disruptive work around proper notice, tenant communication and suitable tenancy or void periods. Record access arrangements and keep tenants informed about the purpose, timetable and contractor contacts.
Understand the proposed cost cap
The government response proposes a maximum required investment of £10,000 per property over ten years, with exemptions where the standard cannot be reached within the cap or particular work is unsuitable. It also proposes protections relating to solid-wall insulation and property value.
These details depend on final legislation and guidance. Do not present the proposed cap or future penalty framework as if it already replaces the rules in force in September 2026.
Budget without relying on a single estimate
Obtain written, comparable quotations that identify the specification, preparatory work, warranties and exclusions. A low headline price may omit ventilation, electrical work, making good or access costs, while a higher quotation may include items that are not needed for the chosen route.
Keep a contingency for defects discovered during the work and avoid scheduling several dependent measures without confirming the sequence. Financial and tax consequences should be checked with the appropriate adviser because an estate or letting agent cannot determine the treatment for every landlord.
Measure outcomes without making guarantees
After work is completed, retain the specification, invoices, guarantees and commissioning records. Update the property schedule and ask whether a new assessment is appropriate, particularly when the changes are material or the existing certificate no longer represents the home.
Energy measures may improve comfort or reduce assessed demand, but an EPC result, bill saving, rental premium or letting speed should not be guaranteed in advance. Actual outcomes depend on the building, installation quality, occupancy, tariffs and the assessment methodology in force.
Tenant communication also matters. Explain how new controls or equipment should be used and provide the operating information supplied by the installer. A technically sound measure can underperform if settings are misunderstood or a maintenance requirement is ignored.
Check funding through current official routes
The Boiler Upgrade Scheme currently offers £7,500 towards eligible hydronic heat-pump installations. Warm Homes support and ECO4 may also assist qualifying households, but eligibility depends on the household, property, work and available funding.
Check GOV.UK, the relevant local authority and the scheme administrator before including support in a budget. Funding can close or change, and an eligibility indication is not the same as approval.
A September checklist for landlords
Use the following sequence for each property rather than applying a portfolio-wide assumption. Record the evidence checked, the action owner and the review date.
- Check the current EPC, expiry date and recommendations on the official register.
- Record improvements made since the assessment and retain supporting evidence.
- Arrange accredited advice where the certificate is outdated or no longer representative.
- Complete building repairs before selecting major energy measures.
- Check planning, listed-building or conservation requirements where relevant.
- Review official funding criteria before relying on a grant in the budget.
- Plan access and disruptive work around the tenancy and proper communication.
- Revisit the plan when final regulations and the reformed EPC methodology are published.
Take the next step with your portfolio
A practical plan connects the EPC record with the condition, tenancy timetable and likely improvement sequence for the individual home. It avoids unsupported county-wide statistics, guaranteed savings and assumptions that every lower-rated property needs the same technology.
