New homes built in England from March 2028 will have to produce 75% less greenhouse gas emissions than those built to 2013 standards. That sounds like a clear step forward. But the same rules won’t apply until then, and the government has delayed the full Future Homes Standard under pressure from housebuilders. The result? Hundreds of thousands of new homes will still be built with gas heating in the meantime, even as energy costs stay high. For anyone buying a new-build home or investing in property, this creates a split market — some homes will be cheap to run, others won’t. Here’s what you actually need to know.

The Future Homes Standard has been more than a decade in the making. It was originally supposed to be published by the previous government, and it replaces a zero-carbon homes standard that was scrapped back in 2015. What’s different this time is that the rules are more specific: solar panels covering an area equal to 40% of the ground-floor area, low-carbon heating like heat pumps, and better insulation are all part of the package. But there’s a catch — the rules don’t fully kick in until 2028, and builders can still install gas boilers until then. If you’re looking at a new build today, you could end up with a home that’s already behind the curve. That matters for resale value and running costs.
What I tend to notice is that most people assume “new build” automatically means “energy efficient.” That’s not always true right now. The gap between the best and worst new homes is wider than it will be after 2028. If you’re buying or investing, the timing of when a home was built — and what standard it meets — matters more than most people realise. Let’s get into the details.
If you’re looking at a new build right now, the first thing to check is whether it has a heat pump or a gas boiler. That single choice could cost or save you hundreds of pounds a year. And it’s not just about the heating — the insulation standard, the presence of solar panels, and the EPC rating all feed into the same picture. The design of UK homes is shifting, but not all builders are moving at the same speed.
The Real Cost of Sustainable vs. Traditional Homes
The headline figure is the £1,000 a year in energy savings the government says homeowners will get under the Future Homes Standard. But the full cost picture is more layered than that. You need to weigh upfront costs, running costs, and what happens when you sell. The table below gives you a side-by-side look at what different EPC ratings actually cost to run — and those numbers are based on current energy prices, not some optimistic future scenario.

| EPC Rating | Typical Annual Heating Cost | Typical Annual Total Energy Cost | Price Premium vs Lower Rating |
|---|---|---|---|
| A (92+) | £200–£300 | £400–£600 | 5–10% higher sale price |
| B (81–91) | £300–£450 | £600–£900 | Moderate premium |
| C (69–80) | £450–£600 | £900–£1,200 | Little to no premium |
| D (55–68) | £600–£900 | £1,300–£1,800 | Often sells at a discount |
The gap between an A-rated home and a D-rated home is roughly £1,000 a year in energy costs. Over a 25-year mortgage, that’s £25,000 — and that’s before you factor in rising energy prices. The Future Homes Standard aims to push all new builds into the A or B band, but the delay means many homes built between now and 2028 will land in C or D. If you’re buying a new build today, the EPC rating tells you more about your future bills than the marketing brochure does.
There’s also the upfront cost. Building a home to the Future Homes Standard costs 5–15% more in construction, according to industry estimates. That cost gets passed to the buyer. But the trade-off is lower running costs and a higher resale value. Properties with EPC A or B ratings typically sell for 5–10% more than lower-rated homes. So the premium you pay upfront is likely to come back when you sell. The question is whether you can afford the higher purchase price now.
And don’t forget the other costs. Stamp duty, legal fees, and survey costs don’t change with the EPC rating, but the type of survey might. A home with a heat pump and solar panels may need a specialist inspection to check the system is installed correctly. That’s an extra £200–£400 on top of the usual survey. Worth factoring in if you’re buying a high-tech home.
What I’d do in this situation: look at the EPC rating before anything else. If you’re choosing between two similar homes, pick the one with the better rating. The running cost difference alone will cover the extra mortgage payment. And if you’re investing in a rental property, tenants are increasingly looking at energy costs — a home with high bills is harder to let. You can also speak to a real estate lawyer if you’re unsure about how the regulations affect your specific purchase.
Common Missteps When Buying or Investing in Eco-Homes
Assuming all new builds are energy efficient
This is the biggest one. A home built in 2025 is not the same as a home built in 2028. Until the Future Homes Standard is mandatory, builders can still use gas boilers and basic insulation. Only 4,000 out of roughly 140,000 new homes last year had heat pumps. That’s less than 3%. So if you’re buying a new build right now, ask specifically what heating system it has and what EPC rating it achieved. Don’t assume.
Overlooking the wood-burning stove loophole
The Future Homes Standard allows wood-burning stoves in new homes. That might sound cosy, but wood burners are highly polluting and not carbon-neutral in the short or medium term. If you’re buying a home with a wood burner, you’re paying for a feature that could undermine the property’s energy efficiency and might face restrictions later. Some local authorities are already considering tighter controls on wood burners in new developments.
Ignoring the heat pump learning curve
Heat pumps work differently from gas boilers. They run at lower temperatures for longer periods, and they need good insulation to work efficiently. Some buyers install a heat pump in a poorly insulated home and end up with high bills. The technology is solid, but it requires the right setup. If you’re buying a home with a heat pump, check the insulation levels and ask about the system’s efficiency rating. A well-installed heat pump in a well-insulated home will save you money. A poorly matched system won’t.
Not factoring in the green premium or discount
Homes with high EPC ratings sell for more, but homes with low ratings are becoming harder to sell. The gap is widening. If you buy a home with a D or E rating today, you might struggle to sell it in five years when more buyers are looking for efficient homes. That’s a real risk if you’re investing for the short to medium term. The market is moving, and the inefficient homes will be the ones left on the market longer. If you’re a landlord and your tenant has a dispute about heating costs or energy efficiency, you may want to consult a tenant and landlord lawyer to understand your obligations.
How the Future Homes Standard Reshapes Property Decisions
What the standard actually requires
From 2028, all new homes in England must produce 75–80% less carbon than those built to 2013 Part L standards. That means:
- Low-carbon heating — almost always a heat pump, not a gas boiler
- Solar panels covering at least 40% of the ground-floor area (with some exceptions)
- High levels of insulation and airtight construction
- Efficient ventilation to prevent damp and heat loss
The standard applies to all new builds, not just large developments. A single self-build home will also need to comply. The government has also confirmed that plug-in solar panels — the kind you can install on a balcony or in a garden — will be available to buy in the UK within months. That’s a shift from the previous ban, and it opens up options for renters and flat owners who can’t install roof panels.
What the delay means for buyers right now
The government delayed the full standard under pressure from housebuilders. That means hundreds of thousands of homes will be built between now and 2028 with gas heating. If you’re buying a new build in 2025, 2026, or 2027, you have a choice: buy a home with a gas boiler and potentially lower upfront cost, or look for a developer who is already building to the higher standard. Some developers are ahead of the curve. Others are waiting until the last possible moment. The energy performance certificate tells you which camp the home falls into. If you’re buying a home with a gas boiler, you might also want to think about the cost of retrofitting a heat pump later — that could run £7,000–£15,000 depending on the property.
Financial incentives that change the math
The Boiler Upgrade Scheme offers £7,500 grants for air source and ground source heat pumps, and it’s been extended to at least 2028. That’s a significant chunk off the installation cost. There are also green mortgages from lenders like Barclays, NatWest, Nationwide, and Halifax that offer 0.1–0.3% lower interest rates for homes with EPC A or B ratings. On a £250,000 mortgage, that could save you £500–£1,500 over the first few years. Some lenders also offer £250–£1,000 cashback for energy-efficient homes. These incentives don’t make a bad investment good, but they can tip the balance if you’re deciding between two similar properties.
Future-proofing: what to look for in a home today
If you’re buying a home now that you plan to keep for 10 years or more, look for these features: good insulation (check the EPC rating), space for a heat pump or existing heat pump, solar panels or a roof that can support them, and double or triple glazing. Avoid homes with electric storage heaters if possible — they’re expensive to run and hard to upgrade. Also check whether the property has a gas boiler that’s nearing the end of its life. Replacing it with a heat pump in the next few years will be cheaper if you plan ahead. If you’re not sure about the legal side of these upgrades — especially if you’re in a leasehold property — a business lawyer can help you understand what permissions you need.
The micro-living trend is another angle worth watching — smaller homes are cheaper to heat and easier to make energy-efficient, which aligns with the Future Homes Standard’s goals.

A Divided Market — And What That Means for You
The Future Homes Standard will eventually make all new homes in England cleaner and cheaper to run. But the delay means the market is split. Homes built before 2028 — especially those with gas boilers and low EPC ratings — will become less attractive to buyers and tenants over time. Homes built after 2028 will have lower running costs and higher resale value. That gap is going to widen as energy prices rise and regulations tighten.
If you’re buying a home today, the single most important thing you can do is check the EPC rating and the heating system. If you’re investing, look for properties that are already energy-efficient or can be upgraded cheaply. The homes that meet the 2028 standard now will be the ones that hold their value best. And if you’re a landlord, remember that the minimum EPC standard for rentals is already C, and that could rise further.
