EPC Certificates across North West London

When do you need an EPC?

You must have commissioned an EPC before you market the property, and it should be available to buyers or tenants at the earliest opportunity. A certificate is valid for ten years. It is not something you renew on a fixed cycle: nothing requires a new one while a tenancy simply continues, and an expired certificate only needs replacing when you next market or let the property. If your property has been assessed within the last decade you may already have a valid one. We will check the national register for you before booking anything, and we will tell you if you do not need us.

What is the minimum EPC rating to let?

Under the Minimum Energy Efficiency Standard, a property in the private rented sector generally cannot be let with an EPC rating of F or G. Since April 2020 that has applied to existing tenancies as well as new ones, not just at the point of letting. Exemptions exist, but they have to be registered on the government's PRS Exemptions Register rather than assumed. E is still the legal minimum as of September 2026. In January 2026 the government confirmed it intends to raise the standard to EPC C, measured against new EPC metrics, for all private tenancies by 1 October 2030, with spending capped at £10,000 per property. The regulations to do that have not yet been made, so treat 2030 as an announced date rather than current law. If your property comes back as F or G, or you want to plan for C, we will set out what the assessment says is holding the rating down and what the realistic routes up look like.

What happens at an EPC assessment?

The assessor measures the property, records the construction of walls, roof and floors, the glazing, the heating system and its controls, the hot water provision and the lighting. Photographic evidence is required for the lodgement. Nothing is invasive and nothing needs to be moved. If loft or boiler documentation is available it helps. A boiler with a known efficiency rating scores better than one that has to be assumed from its age.

How can you improve a poor rating?

The recommendations report that comes with every EPC lists measures in order of impact. In this housing stock the changes that usually move the rating are loft insulation, a modern condensing boiler with proper controls, low-energy lighting throughout and cavity or internal wall insulation where the construction allows it. We will tell you which of those apply to your property and roughly what each is worth in rating points, so you are not spending money on the wrong measure.

Booking and lodgement

We arrange the visit at a time that suits you or your tenant, and the certificate is lodged on the register and sent to you as a PDF, normally within 24 hours. If you need it faster because a marketing deadline is looming, say so when you book and we will tell you honestly whether we can meet it.

Who is this for?

Landlords who need a valid certificate before letting, homeowners marketing a property for sale, and agents who have discovered mid-listing that the EPC has expired.

Which mistakes do we see most often?

The two we see most often are paying for an assessment when a valid certificate is already on the national register (always worth checking first, and we check for you) and assuming a poor rating can be fixed cheaply just before letting. Insulation and heating changes take time and money; finding out you are an F two weeks before a tenancy starts is an expensive discovery. The other is treating the recommendations report as a shopping list and working top to bottom, rather than picking the measures that actually move the rating for your specific construction.
