EPC Upgrades

EPC Upgrades EPC consultancy for South Wales landlords. Before you spend £5k–£20k on upgrades, find out if it's worth it.

Expert advice on whether your property can reach EPC C — before any money is committed.

29/06/2026

The conversation around EPC C by 2030 is changing.

The Government has now published its response to the consultation on improving the energy performance of privately rented homes, giving landlords and investors a much clearer indication of the direction of travel.

While the proposals are not yet law and further detail is still to come, they raise an important question.

**Are landlords focusing on the right problem?**

Much of the discussion centres on how to achieve an EPC C.

In reality, the first question should be whether investing in that particular property makes commercial sense.

Two properties can have the same EPC rating yet require completely different strategies. One may justify further investment. Another may not.

That's why EPC Upgrades takes a different approach.

Before discussing upgrades, we believe landlords should understand:

• Whether the property is likely to achieve the required standard.
• What is actually limiting the rating.
• Whether the investment is commercially justified.
• Whether upgrading, holding or selling is the better long-term decision.

The most expensive mistake isn't necessarily having the wrong EPC.

It's spending money on the wrong property.

A lot of landlords are about to waste money on EPC upgrades.

Not because the work is wrong.

Because the decision is.



Right now, most people are doing this backwards.

They’re starting with upgrades.

New windows. Insulation. Solar. Heating changes.

And only afterwards finding out whether it actually gets them to EPC C.



That’s where the risk is.

Because EPC ratings don’t reward everything equally.

Two landlords can spend the same money…

One reaches C.
The other doesn’t.



I’ve looked at multiple properties recently where money had already been committed…

And the outcome still wasn’t clear.

That’s not a building problem.

That’s a decision problem.



The uncomfortable truth is this:

Some properties will reach C relatively easily.
Some will need targeted changes in the right areas.
Some won’t get there without significant spend.

But most landlords don’t know which category they’re in before they start.



So instead, they follow generic advice.

And hope it works.



If you’re spending £5k–£15k on upgrades, “hoping” is not a strategy.



The landlords getting this right are doing one thing differently:

They’re testing the outcome before committing the money.

Not guessing.

Not relying on recommendations.

Actually understanding what will happen to the rating.



Because once you know that, everything changes.

You either:
• Move forward with confidence
• Adjust the plan
• Or stop before wasting money



If you’ve got a property below C, or you’re about to start upgrading one, you should already know the answer to this:

Will this property actually reach EPC C — and what’s the most cost-effective way to get there?

Most don’t.

That’s where the mistakes start.

Many landlords have seen the recent EPC C discussion and assumed the same thing:

“We’ve got more time.”

Maybe.

But more time does not automatically mean less risk.

The mistake is thinking this is only about the deadline.

It is not.

It is also about cost, capacity, and the risk of making decisions too late.

A large number of rented properties are still below EPC C.

So if landlords keep pushing this down the road, the same thing will happen as always:
• installer demand tightens
• costs rise
• choices narrow
• and weaker properties get exposed too late

There is another issue too.

The way properties are assessed is not guaranteed to stay exactly as it is now. The move toward the Home Energy Model matters. That creates another layer of uncertainty for landlords relying on the idea that today’s assumptions and scoring behaviour will stay frozen.

An EPC lasts 10 years.

So for landlords with properties already close to C, there may be a real advantage in understanding that position now rather than gambling on later.

This is not about panic.

It is about control.

The landlords who leave this until the market is crowded will have less leverage, less flexibility, and a higher chance of overspending.

The landlords who get clarity early can make decisions from a position of strength.

At EPC Upgrades, the focus is not generic EPC advice.

It is helping landlords and investors understand:
• whether EPC C is realistically achievable
• what the model is likely to reward
• and where upgrade spend is most likely to be wasted

Because the expensive mistake is not always failing to upgrade.

Often it is spending money blindly.

After a number of conversations with landlords recently it’s clear there’s still quite a bit of confusion around how EPC ratings are actually calculated.

Many people assume an EPC is simply an inspection of the property.

In reality, the rating is the outcome of a calculation model based on the information recorded during the assessment and how the property performs within that model.

That’s why two properties that appear very similar can sometimes end up with very different EPC ratings.

To help explain how the system works, EPC Upgrades has put together a short guide outlining how EPC assessments are produced under RdSAP and some of the common misunderstandings landlords run into when trying to improve their rating.

The guide is written mainly for landlords, but the same principles apply to anyone buying, selling or renovating a property where the EPC rating may influence the decision.

If you’d like a copy, just comment guide below and we’ll send it over.
