Why Winter Retrofit Matters in 2025
With UK energy prices continually on the rise, many London homeowners are feeling the strain on their household budgets. The older your home, the more vulnerable it is to heat loss through its walls, roof, and windows. This is especially true for period homes, which often have solid walls and little insulation. Winter retrofits like external wall insulation, loft insulation, and draught-proofing are not just about improving comfort, they can drastically reduce your heating costs.
Better insulation improves your home’s U-values, reducing cold spots and condensation, both of which can lead to long-term issues like mould growth. Furthermore, insulating your home can boost your EPC rating, making your home more attractive to future buyers and improving its overall value.
Vector Living offers expert advice on ECO4 London and zero VAT insulation, ensuring that your retrofit project is as cost-effective as possible.
Priority Retrofits Before the Cold Arrives
When preparing your home for winter, it’s crucial to prioritise the upgrades that offer the highest return on investment. Let’s take a closer look at the most important retrofits you should consider:
Insulation First for Fast Savings
To maximise energy savings, insulation is your first line of defence.
Here are the key areas to focus on:
Loft Insulation to 270mm Plus: Insulating your loft to the recommended thickness of 270mm can have an immediate impact on your home’s energy efficiency. This simple measure can prevent heat from escaping through the roof, ensuring that your home stays warmer with less energy.
External Wall Insulation for Period Homes: Solid wall homes, such as Victorian terraces, can benefit significantly from external wall insulation. This insulation type is particularly useful for homes with no cavity walls and can dramatically improve your home’s thermal performance.
Targeted Floor Insulation: If your home suffers from cold draughts or feels chilly in the lower floors, targeted floor insulation can make a big difference. This is especially beneficial for ground floor rooms.
For homes that qualify, you can benefit from zero VAT on insulation materials, making these upgrades even more affordable.
Seal and Upgrade Openings
No amount of insulation will be effective if draughts are entering through gaps around windows, doors, and letterboxes.
Here’s how to seal and upgrade these openings:
Draught-Proofing Frames and Letterboxes: One of the simplest and most cost-effective ways to reduce heat loss is by draught-proofing your doors and windows. This prevents warm air from escaping and cold air from entering, ensuring a more comfortable home.
Consider Double or Triple Glazing: For homes with older windows, double or triple glazing is an excellent option. Not only does it improve insulation, but it also reduces noise from outside, making your home quieter and more comfortable.
Bespoke Joinery for Period Homes: If you live in a period home, bespoke joinery can retain the property’s character while improving airtightness. Vector Living works with skilled craftsmen to create windows and doors that match your home’s original design, all while enhancing its energy efficiency.

Heating That is Heat Pump Ready
Planning for the future is vital, especially when it comes to heating. Heat pumps are becoming more popular as a sustainable and cost-effective solution for heating and cooling homes.
Here’s how you can prepare:
Specify Larger Radiators or Low-Temperature Emitters: Heat pumps work at lower temperatures than conventional boilers, so it’s essential to ensure that your radiators are appropriately sized to cope with this.
Pre-Plan Pipework and Zoning for Future Heat Pumps: If you plan to install a heat pump in the future, ensure your current heating system is compatible. Pre-planning pipework and zoning will save you time and money when it’s time for installation.
Optimise Existing Boilers with Smart Controls: Even if you’re not planning to switch to a heat pump immediately, optimising your current boiler with smart controls can improve efficiency and help reduce your energy bills.

Floors and Finishes that Feel Warm
Ensuring your floors feel warm underfoot is crucial for comfort, especially in colder months.
Consider the following upgrades:
Thermal Underlays Under Engineered Wood and Carpets: Adding a thermal underlay beneath your flooring can provide an extra layer of insulation, helping to keep your home warmer.
Quality Carpets in Bedrooms and Lounges: Carpets provide a natural thermal barrier and can help keep rooms warmer in the winter months.
Improve Acoustic Comfort: By improving both thermal and acoustic comfort, you can create a more relaxing and peaceful environment, perfect for winter.
Bathrooms and Kitchens Built for Winter
The kitchen and bathroom are essential areas of the home that should be designed with winter in mind. Here’s how to optimise these spaces:
Electric or Hydronic Underfloor Heating in Wet Rooms and Utilities: Underfloor heating is a fantastic option for bathrooms and kitchens. It provides consistent warmth, especially in areas that are prone to damp or moisture.
Correctly Sized and Insulated Hot Water Cylinders: Ensuring your hot water cylinders are properly sized and insulated means you’ll have hot water available when you need it, without losing heat.
Fit Mixing Valves and Streamline Pipe Runs: By fitting mixing valves and optimising pipe runs, you’ll ensure that your hot water system operates efficiently, saving energy and money.
Energy-Efficient Touches That Cut Bills
In addition to major retrofits, there are several smaller upgrades that can help reduce your winter bills:
Smart Thermostats, TRVs, and Room Zoning: Installing smart thermostats and room zoning can give you more control over your heating, allowing you to warm specific areas of your home when needed.
LED Lighting and A-Rated Appliances: Switching to LED lighting and A-rated appliances will save you money on your electricity bills while providing better performance.
Vector Living is well-versed in ECO4 London funding options and zero VAT on qualifying energy-saving materials, which can further reduce your costs.
Timing Your Retrofit in London
The ideal time to begin your retrofit project is in autumn, well before the cold weather sets in. A pre-winter survey and a fast-track installation programme can ensure that your home is prepared for the coldest months. Prioritise insulation and other critical upgrades before Christmas to avoid delays and benefit from a warmer, more comfortable home.
