EPC Improvement Works London
For a rental property, the EPC rating is no longer just a certificate — it is a legal threshold. Under the Minimum Energy Efficiency Standard (MEES) it is currently unlawful to let most properties with an EPC below band E. The government has proposed raising that minimum to band C for rented homes, and while that change is still under consultation rather than law, landlords planning ahead are getting the works done now while costs and disruption can be managed.

EPC Improvement Works London
For a rental property, the EPC rating is no longer just a certificate — it is a legal threshold. Under the Minimum Energy Efficiency Standard (MEES) it is currently unlawful to let most properties with an EPC below band E. The government has proposed raising that minimum to band C for rented homes, and while that change is still under consultation rather than law, landlords planning ahead are getting the works done now while costs and disruption can be managed.
Raising a band is rarely one big job — it is a stack of measures, each worth a few points. Loft insulation and cavity or solid-wall insulation (including external render systems on solid walls) make the biggest difference. Improving glazing and draught-proofing, fitting modern heating controls, and switching to LED lighting each add further points, and together they can move a property up a band or more.
We survey the property against its current EPC, work out which measures give the most uplift for the budget, and carry them out as one coordinated package. The result is a property that is cheaper to heat, more comfortable for tenants, and positioned for the proposed band C standard well before any deadline is confirmed.

Our Process, Step by Step
EPC review & measure plan
We review your current EPC and its recommendations, survey the property, and work out which measures give the most band uplift for your budget — loft and wall insulation usually first, then glazing, draught-proofing, heating controls and lighting.
Costed, prioritised quote
You get an itemised quote that prioritises the measures by value, so you can see exactly what each one costs and roughly what it contributes — and decide how far up the bands you want to go ahead of the proposed band C standard.
Insulate, glaze & control
We install loft insulation, fill cavities or apply an external insulated render system to solid walls, improve glazing and draught-proofing, fit modern heating controls and TRVs, and upgrade lighting to LED — carried out as one coordinated package.
Finish & re-assessment
We make good and clean down, then you can arrange a fresh EPC assessment to capture the improved rating. We advise on which measures the assessor will credit so the new certificate reflects the work that was done.
Frequently Asked Questions
It depends on which measures the property needs. Loft insulation starts from around £400 and gives a high uplift for the cost. Cavity wall insulation is £500–£1,500, and external solid-wall insulation render systems from around £8,000. Draught-proofing and heating controls run £300–£1,200, and an LED lighting upgrade from around £150. We survey against your current EPC and quote a prioritised, costed plan.
Under the Minimum Energy Efficiency Standard (MEES) it is currently unlawful to grant or continue most tenancies on a property with an EPC below band E. The government has proposed raising the minimum to band C for rented homes, but that change is still under consultation and is not yet law. Landlords are improving now to stay ahead of the proposed standard rather than waiting for a confirmed deadline.
Insulation usually gives the biggest uplift: loft insulation and cavity or solid-wall insulation make the largest difference to the rating. Beyond that, improved glazing and draught-proofing, modern heating controls and a more efficient heating system, and a switch to LED lighting each add points. We model which combination moves your property up a band most cost-effectively before recommending the works.
No. The proposed requirement for rented homes to reach EPC band C has been put forward by the government but remains under consultation — it is a proposal, not enacted law, and no firm deadline is currently in force. The current legal minimum under MEES remains band E. We help landlords improve ahead of the proposed standard so they are not caught out if and when it is confirmed.
Yes. Rather than booking insulation, glazing, heating controls and lighting as separate jobs, we deliver the measures as one coordinated package against a single prioritised plan. That keeps disruption to one programme, lets us sequence the work efficiently, and means the property is ready for a fresh EPC assessment as soon as the improvements are complete.
