What happened: the April 2026 price cap changed your unit rates, not your “total bill”
From 1 April 2026, Ofgem’s updated energy price cap came into effect for the April–June 2026 quarter. The big headline is that typical household bills are down by around 7% (roughly £117 a year on average for homes paying by Direct Debit, based on standard “typical use” assumptions).
It’s important to understand what that actually means in practice. The price cap is not a cap on your total bill. It’s a limit on the maximum unit price (pence per kWh) and standing charge your supplier can charge customers on a standard variable tariff. If you use more energy than a “typical” household, you’ll still pay more. If you use less, you’ll pay less.
So yes—this change is good news. But if your home’s heating system is wasting energy, the cap reduction can disappear into the cracks in your building fabric or the inefficiencies in an ageing boiler.
Why it matters: heating is where most households spend (and waste) energy
For most gas-heated homes, space heating is the largest slice of energy consumption, followed by hot water. A shift in the energy cap affects the price you pay for each unit, but the biggest lever you control is how many units your home needs to stay comfortable.
In our area—Bordon, Whitehill, Liphook, Alton, Farnham and Haslemere—we see a real mix of housing: everything from newer estates and renovated properties to older homes with solid walls, open chimneys, suspended timber floors and less predictable insulation. Those characteristics matter more than most people realise. Two neighbours can face very different bills even on the same tariff.
Practically, the price cap drop creates a small breathing space. The best move homeowners can make is to use that breathing space to get their system running efficiently before the next quarter’s cap adjustment (and before next winter planning starts in earnest).
What it means technically: how the cap shows up in your boiler, radiators and controls
The cap change affects your fuel cost per kWh, but the technical drivers of heating spend remain the same. Here are the main ones we see on call-outs and services across East Hampshire and West Surrey.
1) Boiler efficiency depends on return temperature (not just the badge on the front)
If you have a condensing gas boiler (most installed in the last 15–20 years), it only achieves its high efficiency when it can run in condensing mode. In plain English: the boiler needs relatively cool water coming back from the radiators so that water vapour in the flue gas condenses and releases extra heat into the system.
If your system is set to a high flow temperature (e.g. 75–80°C), your radiators may be hot—but your boiler may be condensing less, using more gas than necessary. Many homes can comfortably heat at 55–65°C flow in milder weather (which is exactly what April–June usually brings).
The price cap reduction is a reminder: if you can reduce gas use by improving efficiency, you benefit whether prices go up or down next quarter.
2) Boiler cycling wastes energy—often caused by oversizing or poor control setup
Boilers are frequently oversized, especially where a bigger model was fitted “just in case”. An oversized boiler paired with basic controls can short-cycle (firing up, switching off, firing up again). That wastes fuel and increases wear on components.
Better control (weather compensation, load compensation, smart room stats with proper zoning) helps the boiler modulate smoothly. Even without new hardware, correctly balancing radiators and setting sensible flow temperatures can reduce cycling.
3) Hot water settings matter more than people think
On combi boilers, DHW temperature is often set higher than needed. If you’re mixing lots of cold at the tap, you’re essentially paying to overheat water and then cool it down. For many households, comfortable DHW sits around 45–50°C at the tap (the boiler setpoint will vary). Safe hot water matters, but so does needless overheating.
On system boilers with cylinders, the key is maintaining safe storage temperatures (typically 60°C in the cylinder to manage legionella risk) while avoiding long reheat times caused by poor coil performance, sludge, or incorrect programmer settings.
4) System cleanliness affects heat transfer
Sludge, magnetite and limescale reduce heat transfer and flow rates. That means rooms take longer to warm up and the boiler runs longer to achieve the same comfort level. If you’re in parts of Farnham, Alton or Haslemere where we regularly see older pipework and mixed-metal systems, a magnetic filter, clean water and correct inhibitor levels are not “nice to haves”—they’re foundational to efficiency.
What it means financially: your standing charge stays, so usage reduction is still king
A typical “price cap drop” is a combination of changes to the unit rate and the standing charge. Even when unit rates fall, standing charges can remain stubbornly significant. That’s why many households don’t feel the headline savings as strongly as they expect—especially lower-usage homes, where standing charges form a bigger proportion of the bill.
Here’s how to think about it as a homeowner:
- You can’t control standing charges on a standard variable tariff.
- You can control your kWh usage through efficiency and controls.
- Small efficiency gains compound: shaving 5–10% off heating use has value every quarter, regardless of where the cap goes next.
Also note that the “£117 a year” style figure is an average based on typical usage. If you live in a larger, less insulated property on the edge of Liphook or in a rural pocket outside Whitehill, your heating demand may be above the average, so your absolute savings from a percentage drop could be higher—but so is your exposure if prices rise again.
What it means locally: spring is your best window for low-disruption improvements
April to June is an underrated season for heating work. Across Bordon and Whitehill, we often see households wait until the first cold snap to address recurring boiler issues or underperforming radiators. By that point, demand is high and any failure feels urgent.
Spring is different:
- Heating is still occasionally needed on chilly mornings, so you can test changes without relying on the system 24/7.
- You can schedule servicing and upgrades with less disruption.
- If you have a property in Haslemere or Farnham with older construction, it’s a good time to tackle draughtproofing and insulation measures before summer tasks take over.
Even in areas with a lot of newer housing stock, like parts of Bordon, we regularly find controls left in default settings that never suited the household’s routine. Those are quick wins.
What homeowners should do next: practical steps to turn a cap drop into real savings
The cap reduction is helpful, but the most reliable savings come from improved system efficiency and smarter use. These are actions you can take now, in a sensible order.
Step 1: Check your tariff and billing basics (30 minutes)
- If you’re on a standard variable tariff, you’re protected by the cap—but you’re also exposed to future quarterly shifts. Consider whether a fixed tariff suits your risk tolerance (not everyone benefits from fixing).
- Submit accurate meter readings (or ensure your smart meter is communicating). Estimated bills can mask real changes in consumption.
- Keep an eye on gas kWh usage month to month, not just pounds and pence. Usage tells the truth about efficiency.
Step 2: Optimise boiler flow temperature for the season (15–30 minutes)
If you have a combi or system boiler with adjustable central heating flow temperature, consider lowering it gradually and seeing if comfort remains good. Many homes can run cooler in spring while staying comfortable.
Plain-English rule: set it as low as you can while still heating the house properly. If rooms struggle to warm up, nudge it back up a little. This encourages condensing and reduces gas burn.
If you’re unsure which control adjusts CH flow temperature, or your boiler has complicated menus, get it checked—guessing can lead to nuisance lockouts on some models.
Step 3: Use controls properly (and avoid the two most common mistakes)
Controls don’t save money simply by being “smart”. They save money when they match the way you live.
- Mistake one: running a single temperature all day because “it’s more efficient” (not always true). If you’re out most of the day, timed schedules can reduce run hours significantly.
- Mistake two: using TRVs as on/off switches while the room thermostat fights against them. Ideally, your main thermostat sits in a representative area and TRVs fine-tune other rooms.
If you’re in a larger home in Alton or Farnham, zoning upstairs/downstairs can make a noticeable difference, particularly in spring and autumn when solar gains vary by room.
Step 4: Get the system running like it should (service + system health)
A routine boiler service is about safety first, but it also keeps efficiency where it should be: clean combustion, correct gas rate where applicable, and early identification of failing components. If you’ve had:
- radiators cold at the bottom,
- noisy pipes or pump,
- regular pressure loss,
- or one room that never heats properly,
…those are signs to look beyond a basic service and assess whether balancing, powerflushing, inhibitor top-up, air removal, or radiator upgrades are needed.
Step 5: Stop paying to heat the outdoors (drafts and insulation)
This is where homeowners in older properties around Haslemere and parts of Liphook can make huge gains without touching the boiler:
- Draughtproof external doors and sash windows properly (not with temporary foam that ruins timber).
- Check loft insulation depth and coverage—gaps around eaves and hatches are common.
- Insulate hot water pipes in airing cupboards and lofts; it’s inexpensive and immediately reduces losses.
Lower energy prices can tempt people to postpone this work. But fabric improvements last decades and reduce the amount of heat your home needs in the first place.
A realistic expectation: enjoy the drop, but don’t build your household budget around it
The MoneyWeek coverage rightly notes that price cap levels remain subject to wholesale prices and policy costs. That’s the key caution for homeowners. You might see lower unit rates now, but the cap can move again next quarter. The best protection is a home that needs less energy to stay warm and deliver hot water comfortably.
If you’re not sure where your biggest losses are, start by tracking gas usage weekly for a month and pairing that with a few targeted checks: flow temperature, schedules and radiator performance. In many homes in Bordon, Whitehill and the surrounding villages, we can often save more through correct setup than people achieve from switching tariffs.
