Want to Save on Energy Bills This Winter? Start Here
If you’re looking for practical, trusted ways to make your home warmer, greener and cheaper to run this winter, these are the four most effective steps - from zero-cost actions to future-proof upgrades.
This post answers the questions often asked by homeowners:
Does lowering my boiler temperature really save money?
What can I do before installing a heat pump?
How can I make my home more efficient?
Are there any grants available?
1. Zero-Cost: Turn Down Your Boiler Flow Temperature
Most boilers in the UK are running hotter than they need to. By reducing the flow temperature - the temperature of water leaving your boiler - to around 60 °C, your system works more efficiently.
Why it works
Condensing boilers only reach top efficiency when the return water is cool enough to condense. Lower flow = more condensing = less gas burned.
How to do it
Find your central heating temperature setting (on your boiler, not the room thermostat).
Reduce it to around 60 °C.
Let your home warm gradually - it may take longer, but uses less energy.
If your rooms don’t quite reach target temperature, your radiators might be undersized. That’s easily fixable and part of making your home heat-pump ready.

2. Low-Cost: Draught-Proof Your Home
Even with the heating on, some homes still feel cold. In fact, a draughty property can exchange two full house-volumes of cold air every hour - air that must be reheated from outdoor to indoor temperature. And moving air is much colder than still air.
Draught-proofing stops that waste while keeping controlled ventilation where it’s needed.
Start with:
Brush or foam seals around windows and doors
Letterbox brushes and keyhole covers
Seal gaps under skirting boards and around pipes
Insulate and seal your loft hatch
Once sealed, your home stays warm longer, your heating runs less often, and comfort improves dramatically.
3. Medium-Cost: Insulation and Radiator Upgrades
Insulation and heating distribution are the bridge between comfort and long-term efficiency.
Loft & Wall Insulation
The Energy Saving Trust lists loft and cavity wall insulation among the top ways to reduce heat loss. If your loft insulation is below 270 mm, it’s time to top it up.
When adding more insulation above the joist height, you’ll need loft pillars or raised boarding systems to keep insulation fluffy, not compressed.
Check if your walls have empty cavities — if so, cavity fill insulation is one of the best-value measures around.

Radiator Upgrades
If you’ve turned down your boiler flow temperature, larger or newer radiators will help deliver the same warmth more efficiently. This step is key to being heat-pump ready later.

4. Higher-Cost: Solar, Heat Pump and Battery - The Magic Combo
Our speciality is combining solar panels, a heat pump and a home battery to bring you as close as possible to zero bills. We've done this for customers all over Surrey, Berkshire, Hampshire, Surbiton and Richmond.
How it works
Heat pump: Uses electricity to move heat from outdoors into your home - typically three times more efficiently than a boiler.
Solar PV: Generates your own electricity to run your heat pump and appliances.
Battery storage: Stores excess solar energy for evening use.
These technologies reinforce each other - solar feeds your heat pump, battery smooths demand, and the result is low running costs and a smaller carbon footprint.

Grants and Support You Could Qualify For
The UK government currently funds several schemes to help households cut costs and carbon:
Scheme | What it covers | Grant value | Who’s eligible |
Boiler Upgrade Scheme (BUS) | Air & ground source heat pumps | Up to £7,500 | Owner-occupiers in England & Wales |
Great British Insulation Scheme (GBIS) | Loft and cavity wall insulation | Free or discounted | Homes EPC D–G, certain council tax bands |
ECO4 | Efficiency and heating upgrades | Fully funded for some | Low-income or vulnerable households |
Local Authority & Warm Homes initiatives | Regional retrofit measures | Varies | Check your local council website |
And more support is coming:
The UK government has recommitted £13.2 billion to the forthcoming Warm Homes Plan, a nationwide programme that will fund home insulation, energy efficiency, and low-carbon heating upgrades. Details are expected soon - and we’ll update our blog as soon as they’re announced.

How the Four Steps Build on Each Other
Zero-cost: Turn down your flow temperature.
Low-cost: Seal draughts and stabilise your home’s heat retention.
Medium-cost: Insulate and upgrade radiators to run efficiently at lower temperatures.
High-investment: Add solar, heat pump, and battery — and move toward zero bills.
Each stage makes the next one easier, cheaper, and more impactful.
