EPC C by 2030: What London Landlords Need to Do Now

What do London landlords need to do about EPC C by 2030?

Privately rented homes in England must reach EPC band C for all tenancies from 1 October 2030. The government confirmed the target in January 2026 alongside the Warm Homes Plan, with a landlord cost cap of £10,000 per property, or 10% of the property’s value if that is lower. Legislation is targeted for 2027.

What landlords should do now is find out where each property stands: check the current EPC, identify which measures could close the gap to band C, and schedule the work into void periods over the next four years. Until 2030, the existing minimum of band E still applies, with penalties of up to £5,000 per property.

This guide explains what is already law, what has been confirmed, how EPC reform affects your rating, and which improvements tend to suit London housing, from Victorian terraces to purpose-built flats.

What is the current minimum EPC rating for rented homes?

Band E. Under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015, known as the Minimum Energy Efficiency Standards or MEES, a privately rented home must have an EPC rating of E or above unless a valid exemption is registered. Properties rated F or G cannot lawfully be let without one.

Exemptions are recorded on a government exemptions register, and they cover specific situations set out in the regulations. Registering an exemption is the landlord’s responsibility, and it must be in place before relying on it.

A domestic EPC is valid for 10 years. It is required when a property is built, sold or rented, and it must be given to prospective tenants. Local authorities enforce MEES and can impose penalties of up to £5,000 per property.

What exactly has been confirmed for 2030?

The headline is band C for all private tenancies from 1 October 2030, with a cap on what landlords must spend. The detail will be set out in regulations, which the government is targeting for 2027.

The cost cap is £10,000 per property, or 10% of the property’s value if that is lower. The 10% alternative only applies where a property is worth less than £100,000, so for most London rentals the £10,000 figure is the relevant cap. Which costs count towards it, and how exemptions will work once the cap is reached, will be confirmed in the regulations.

How will EPC reform and the Home Energy Model affect my rating?

Existing EPCs remain valid for their full 10-year term, so a certificate lodged today does not become invalid when the new format arrives. On 9 March 2026 the government announced that the launch of new-format domestic EPCs and the Home Energy Model, the new calculation method, has moved to the second half of 2027.

The new-format EPC will report several headline metrics rather than a single rating: fabric performance, heating system, smart readiness and energy cost. How these metrics will be used to judge compliance with the band C standard will be confirmed in the regulations.

For planning purposes, the practical point is that fabric (insulation, windows, draught-proofing) and the heating system are central to both the current and the new approach. Improvements in those areas are unlikely to be wasted, whichever way the final rules are written.

Which energy improvements suit London homes?

It depends heavily on the building. London’s private rented stock ranges from solid-walled Victorian and Edwardian terraces, many now split into flats, to inter-war houses in the outer boroughs and purpose-built blocks from every decade. The table gives a qualitative guide; an EPC assessment of your own property will show which measures are relevant.

On London jobs, our assessors often see older conversions with a working boiler but no room thermostat or radiator valves, an uninsulated hot water cylinder, or a loft that has never been topped up. These are usually the simplest gaps to close, and they are worth checking before committing to anything more disruptive.

What can I do in a Victorian terrace with solid walls?

Start with the low-disruption measures and treat solid wall insulation as a later, carefully planned step. Solid brick walls lose more heat than filled cavity walls, but they also behave differently with moisture, so insulation must be specified and detailed with care to avoid trapping damp.

Many Victorian and Edwardian streets in London sit within conservation areas, and some properties are listed. External wall insulation and replacement windows on front elevations often need consent. Internal measures such as secondary glazing, loft insulation and heating upgrades usually do not need planning permission, although a listed building may need consent even for internal work. Always check with your borough’s planning team before ordering work that changes the outside of the building.

For a typical converted flat in a terrace, the realistic route to band C can combine heating controls, an efficient heating system, LED lighting, cylinder insulation where relevant and better glazing. Whether that is enough depends on the flat’s position in the building, its exposed walls and its current rating, which is why a current EPC is the right starting point.

What about purpose-built flats and mansion blocks?

In flats, the position of the flat and the terms of the lease matter as much as the measures themselves. A mid-floor flat with heated neighbours above, below and to the sides has fewer exposed surfaces than a top-floor or ground-floor flat in the same block, so two identical layouts can rate differently.

The lease often reserves the external walls, roof and windows to the freeholder, so a leaseholder landlord may need the freeholder’s consent before insulating walls or replacing windows. Measures inside the flat, such as heating controls, LED lighting, cylinder insulation and, where permitted, secondary glazing, are usually within your own control.

Flats heated by older electric storage or panel heaters can rate poorly on current EPCs because the rating reflects running costs, so the heating system is often the first area to look at. Where a block has communal heating, an individual landlord has less control, and the freeholder or managing agent will need to be involved in any plan.

Why start now rather than closer to 2030?

Because the most practical time to do disruptive work is between tenancies, and a property may only have a few void periods before October 2030. Starting now also leaves time for planning or listed building consent where it is needed, and for a second round of work if the first does not reach band C.

There is also a shorter deadline. London landlords must provide their most recent EPC to the Private Rented Sector Database by 14 October 2027, so it makes sense for every property to have a current, accurate certificate by then in any case.

What is the step-by-step plan for reaching band C?

Work through each property in the same order, so you spend money where it moves the rating and keep a clear record for the cost cap.

1. Find the current EPC. Check the rating, the lodgement date and when it expires for every property you let.
2. Read the recommendations. Each EPC lists suggested measures and the potential rating if they were carried out.
3. Decide whether you need a fresh assessment. If you have made improvements since the last EPC, or it is close to expiry, a new EPC gives an accurate baseline.
4. Do the low-disruption measures first. Heating controls, LED lighting, cylinder insulation and loft top-ups can often be done while a tenant is in place.
5. Plan bigger works for void periods. Insulation, glazing and heating system replacement are easier between tenancies. Check conservation area and listed building rules first.
6. Keep every invoice. Records of what you spent, and on what, are likely to be needed to show spending against the £10,000 cap.
7. Re-assess after the work. A new EPC lodged after improvements is the only way the register will reflect them.
8. Review exemptions if needed. If a property cannot reach band C within the cap, check the exemption rules once the regulations are published and register any that apply.

If your plan includes a new boiler, our boiler installation service starts from £1,499 inc. VAT, with a typical combi replacement in London costing £1,800–£2,800 depending on the model, flue and pipework.

When should I book a new EPC?

Book one when your current EPC is near expiry, after you complete improvement works, or when you need an accurate baseline to plan for 2030. You also need a valid EPC whenever you let a property, and London landlords must provide the most recent EPC when registering on the Private Rented Sector Database between 15 July and 14 October 2027.

EPCs are produced by accredited Domestic/Non-Domestic Energy Assessors (Elmhurst / Stroma accreditation schemes). A domestic EPC from BritCertify costs from £89 inc. VAT for 1–3 bedrooms, £99 for 4 bedrooms, £109 for 5 bedrooms and £119 for 6 bedrooms. For the full set of certificates a rental needs alongside the EPC, see our London landlord compliance checklist.

Do commercial landlords face the same deadline?

The band C decision for 2030 covers privately rented homes. Non-domestic properties have their own MEES regime, which currently requires a minimum rating of E, with penalties linked to rateable value that can reach £150,000.

Commercial landlords should keep track of non-domestic proposals separately and make sure every let unit has a valid EPC. Our commercial EPC starts at £299 inc. VAT for premises up to 200 m².
