Please read first. This is a trade-verified improvement pathway and cost appraisal. It is not an official Energy Performance Certificate (EPC) and does not replace an assessment by an accredited Domestic Energy Assessor.

The problemYou're asking: “What do I actually need to spend — and is it even worth it?”

From 1 October 2030, a property rated below EPC C cannot legally be let.

That is confirmed law, not a proposal. Every landlord holding a D, E, F, or G rated rental has this problem — whether they have looked at it yet or not.

The trouble is that nobody tells you the number. You don't know which measures move the rating, what they cost, or whether the total lands under the £10,000 spending cap. So the decision keeps getting pushed down the road — and the deadline keeps getting closer.

There are only two honest answers to that question: a costed pathway to C, or the case that the smart move is to sell. This appraisal gives you whichever one the numbers actually support.

A £297 answer, before you spend anything at all.

What your appraisal covers

A structured, property-specific pathway — built from the EPC register, your construction type, and a trade cost database. Not a generic checklist.

1Current EPC rating confirmed
Your existing rating taken from the EPC register, so the whole appraisal starts from the correct baseline.
2Construction type and age band
Property construction and age band identified — this determines which improvement measures are realistic and which are likely to move the rating.
3Improvement measures ranked
The most impactful measures for your property, ranked by cost-effectiveness — cheapest route to the rating first.
4Cost ranges for each measure
Cost ranges drawn from a trade cost database, so you see what each measure is likely to cost at real trade rates rather than a retail estimate.
5Estimated new band after each measure
The estimated EPC band after each measure, so you can see exactly where the rating lands as the works build up.
6Recommended pathway to C
The cheapest credible route to EPC C for your specific property, sequenced.
7Total estimated investment to reach C
The total estimated spend to reach C — and how that compares to the £10,000 cost cap, which is where the exemption question is decided.
8Building control or planning flags
Whether any recommended measure would require building control or planning consent, flagged before you commit to it.
9Recommended professionals
The trades you will need to deliver the pathway — insulation installer, heating engineer, and so on.
10Timeline recommendation and the sell option
A recommended timeline to be compliant well before the deadline — and, where the numbers point that way, the honest case for selling instead of retrofitting.

Two honest outcomes. Never a sales pitch.

We don't sell the works and we don't earn from a sale. The appraisal points wherever the numbers point.

Retrofit — here's the pathway

If reaching C stacks up within the cost cap, you get the cheapest credible route: the measures, the order, the trade-rate costs, and the professionals to deliver it. A clear plan you can act on and budget against.

Sell — here's why it's the better move

If the works don't justify the spend, or an exemption is the realistic route, we say so plainly. Sometimes the honest answer is that selling the property is the stronger financial decision — and you'll know that before you pour money into it.

The factsWhat the rules actually say
·EPC C required by 1 October 2030
From this date, properties rated below EPC C cannot be legally let. This is the deadline the whole appraisal is built around.
·£10,000 cost cap and a 10-year exemption
Required spend to reach EPC C is capped at £10,000 per property. Where compliant works cannot be achieved within the cap, a 10-year exemption may apply — the appraisal shows you whether that applies to you.
·Fines up to £30,000
Non-compliance carries penalties of up to £30,000 — which is a large part of why getting ahead of this now, not in 2029, matters.
·New EPC methodology from 1 October 2029
The EPC assessment methodology is changing from 1 October 2029, which can affect how a property is rated and how measures score.
·PRS database from late 2026
A Private Rented Sector database is due to come in from late 2026, adding a registration layer landlords will need to be ready for.

AboutWho produces the appraisal

Andy — AssetEye

16 years in UK property from the trade side. The whole point of this appraisal is that the costs come from someone who has actually done the works — real trade rates, not retail estimates or guesswork. That is what makes the number you get worth trusting.

And because AssetEye earns nothing from the works and nothing from a sale, the recommendation is only ever pointed at what the property actually needs.

Questions, answered straight.

Is this an official EPC?
No. This is a trade-verified improvement pathway and cost appraisal. It is not an official Energy Performance Certificate and does not replace an assessment by an accredited Domestic Energy Assessor. Official EPCs can only be produced and lodged by an accredited assessor. This appraisal tells you what the works are likely to be and cost — an EPC certifies the rating.
What if the honest answer is to sell?
Then that is what the appraisal says. It is not a sales pitch for retrofit works. Where the numbers show that reaching C isn't worth the spend, or that an exemption is the realistic route, you'll get that plainly — before you commit money to works that don't pay off.
Do you need to visit the property?
No. The appraisal is produced from the EPC register rating, the property's construction type and age, and a trade cost database. No site visit is required, which is part of how it can be delivered within 72 hours.
What's the difference between £297 and the £10,000 cost cap?
£10,000 is the legal cap on what you may have to spend to bring a property to EPC C. £297 is what it costs to find out, in advance, what your property specifically needs — so you spend the works budget wisely, or don't spend it at all.
How quickly will I get it?
Within 72 hours of receiving your property details after payment.
Is this financial or investment advice?
No. AssetEye provides property risk intelligence for awareness and planning purposes only. It is not investment, financial, legal, or mortgage advice. Always seek qualified professional advice before committing capital.
I manage properties for landlords — can I offer this?
Yes. Letting agents can offer the appraisal to their landlord clients on a white-label basis. See agent partnerships or email andy@asseteye.co.uk.
