It's one of the first questions people ask when they start looking at Park Homes: will it actually be warm in January? A Park Home doesn't look like a brick-and-mortar house, so many buyers assume it won't hold heat like one. For a modern residential Park Home, that assumption is out of date. How warm a Park Home stays in winter comes down to one thing above all else: the standard it was built to.
The Build Standard Behind Warm Park Homes
Every new residential Park Home in the UK must be manufactured to BS 3632:2023, the British Standard for homes designed as permanent, year-round residences. It came into force in September 2023 and tightened the thermal requirements of the previous 2015 version.
The standard sets maximum U-values for the external structure. A U-value measures how easily heat passes through a wall, floor or roof, so the lower the number, the less heat you'll lose. Under BS 3632:2023, a new Park Home must achieve:
- 0.30 W/m²K or better for walls
- 0.26 W/m²K or better for floors
- 0.20 W/m²K or better for roofs
While the thermal performance requirements of BS 3632:2023 are different from those set out in Part L of the Building Regulations for conventional new-build homes, the latest standard represents an important step forward in the energy efficiency of modern Park Homes. Compared with previous generations of Park Homes, today's homes benefit from improved insulation and thermal performance, helping to retain heat and provide a comfortable living environment throughout the year. Many manufacturers also go beyond the minimum requirements, incorporating additional features designed to improve energy efficiency and reduce heat loss.
Homes built by members of the National Caravan Council (NCC) also come with an Energy Efficiency Calculation, so you'll see on paper how the home will perform before you buy. Double glazing, insulated floors and full central heating are standard, not upgrades.
How Quickly Does a Park Bungalow Heat Up?
Beyond the insulation figures, the shape of the home works in your favour. Like other single-storey homes, a Park Bungalow is compact and all on one level, so there's no stairwell pulling warm air up to landings and spare bedrooms you rarely use. You'll be heating the rooms you actually live in, and nothing else.
That smaller heated volume means the home will respond quickly. Turn the heating on after a frosty dog walk and the living room will be comfortable in a few minutes. Combined with modern boilers, radiators in every room and tightly sealed double glazing, a new Park Home holds an even temperature through the coldest months without the system working flat out.

Older Park Homes Tell a Different Story
One caveat is that not every Park Home was built this way. Homes manufactured before the modern versions of BS 3632, some of them dating back decades, can have thin walls, single glazing and little floor insulation. Age UK has campaigned on exactly this problem, because residents of older models were struggling with cold rooms and high heating bills. That reputation still colours how people view Park Homes today, even though it describes a different generation of housing.
If you're buying second-hand, ask when the home was manufactured and to which version of the standard. Look for the manufacturer's compliance certificate and the NCC badge. Older homes can be improved with external wall cladding and underfloor insulation, but that's a cost to factor in. A new home built to the current standard removes the question entirely.
Winter Heating Costs Are Lower in a Modern Park Bungalow
Warmth and running costs go hand in hand. Because a modern Park Home has less volume to heat and loses less of that heat through its structure, winter energy bills tend to be lower than in an older house of similar size. Many residents weighing up staying put and downsizing often find the heating bill alone makes the case, and the difference shows up right from the first winter.
Your exact costs will depend on the home's size, the heating system and how you use it, so treat any blanket claim with caution. What you can rely on is the Energy Efficiency Calculation supplied with an NCC-approved new home. It will give you a realistic picture of performance before you commit, which is more than most period properties can offer.
Ask When It Was Built, Not Whether It'll Be Warm
The question "how warm are Park Homes in winter?" has no single answer, because Park Homes span sixty years of build quality. A model from the 1980s and a home built to BS 3632:2023 share a plot type and little else. So the better question for any buyer is a simpler one: which standard was this home built to?
If the answer is the current standard, you'll get a warm, efficient home that handles a British winter as well as any new build. Every home at a Regency Living development is built to BS 3632, so if you'd like to see how a modern Park Bungalow performs when the temperature drops, winter is honestly the best time to visit one.
