The five-year EPC exemption almost everyone misses
The EPC Band C deadline of October 2030 is widely understood.
The exemption framework that sits alongside it is not. Most landlords are aware that exemptions exist in principle. Far fewer understand the full range of circumstances that qualify, how long those exemptions last, or how straightforward the registration process actually is. That knowledge gap is costing landlords time, unnecessary expenditure, and in some cases compliance anxiety about properties that would qualify for a registered exemption without any improvement work at all.
What exemptions are available and how long they last
The government confirmed in January 2026 that all privately rented properties must achieve a minimum EPC Band C by 1 October 2030, or hold a valid registered exemption on the Private Rented Sector Exemptions Register. The government has recently launched an updated version of that register, now operating through its One Login service, ahead of the 2030 overhaul.
Most exemption categories are valid for five years from the date of registration. The exception is the new landlord exemption, which lasts six months and applies when a landlord has recently acquired a property and needs time to assess its improvement requirements. The third-party consent exemption lasts either five years or until the current tenancy ends, whichever comes sooner.
The exemptions most landlords are unaware of
The cost cap exemption is the most commonly discussed, covering situations where the full £10,000 permitted spend would not bring the property to Band C. What landlords frequently miss is that this exemption can be claimed after spending up to the cap, not only after spending nothing. A landlord who has made genuine improvements but cannot reach Band C despite maximum permitted investment can register the exemption and continue to let the property legally for the duration of its validity.
The wall insulation exemption is less well known but applies to a significant number of properties. Where cavity wall or internal insulation would cause structural damage or damp penetration, the landlord can register an exemption with evidence from a qualified assessor. This applies particularly to solid-wall Victorian and Edwardian properties where the standard improvement recommendations carry genuine structural risk.
The third-party consent exemption is the one most frequently overlooked. Where a freeholder refuses permission for improvement works, where a tenant refuses access to carry them out, or where a planning authority declines consent for works to a listed or conservation area property, the landlord has a legitimate basis to register an exemption. The critical requirement is evidence: consent must have been sought in writing and the refusal must be documented. Landlords who have experienced informal verbal refusals without written records cannot rely on this exemption. Those who have sought and documented refusals can.
The devaluation exemption applies where a qualified surveyor confirms that carrying out the recommended improvements would reduce the property’s value by more than 5%. For properties with specific character or unusual construction, this can be a relevant route.
The opportunity landlords are missing by waiting
Beyond the exemption framework, there is a timing opportunity that very few landlords have acted on. Any property that obtains an EPC rating of Band C or above under the current assessment methodology before October 2029 will be recognised as compliant for ten years from the date of that certificate. A certificate obtained now would remain valid until 2035 or beyond, covering the entire 2030 compliance deadline without any further assessment under the new Home Energy Model that replaces the current system from October 2029.
For properties that are close to Band C and where modest improvements would achieve it, acting now to obtain a compliant certificate before the methodology changes is the most commercially effective move available. For properties where the exemption route is more appropriate, understanding which category applies and registering it promptly is equally important.
