At City Plumbing, we believe making your home warmer and more efficient shouldn't require major renovations or a big budget. Whether you're a homeowner aiming to cut energy bills or a tenant wanting comfort without turning up the heat, small changes can make a big difference.
Your EPC is more than a survey rating; it’s a guide to a comfortable, affordable home. This quick but helpful article highlights the best EPC improvements under £200, all with professional-grade supplies, available now at City Plumbing in-store or online.
From easy heating controls to simple insulation hacks, learn how to boost your home’s energy score and keep your money inside.
Homeowner & Tenant EPC Quick Wins: Why These Matter for Your EPC Score
For EPC ratings, assessors consider not just the building, but also its energy waste. Completing these four steps can help show your home is efficient, controlled, and insulated: potentially a fast way to upgrade to a D rating to even a C rating.
1. The "Golden Rule" of Lighting: Switch to LEDs
One of the easiest ways to gain a few points on an EPC is to ensure that 100% of your fixed lighting uses low-energy bulbs.
- The Fix: Replace all old incandescent or halogen bulbs with LED alternatives.
- The Benefit: They use up to 90% less electricity than old-fashioned bulbs and last for years, meaning you’ll rarely need a ladder to change a blown bulb again.
- EPC Impact: Small but vital if you're on the cusp of a higher grade (e.g., D to C).
- Estimated Cost: £20 – £50 for a whole house.
- DIY Difficulty: Very Easy (as simple as changing a lightbulb!).
Stock up on multi-packs of LED Energy-Saving Bulbs at City Plumbing to swap out every bulb in one go.
2. Insulate the "Heart": Hot Water Cylinder Jacket
If you have a traditional hot water tank that feels warm to the touch, you're losing money. An uninsulated tank is a major red flag for EPC assessors.
- The Fix: Wrap the tank in a British Standard insulating jacket (at least 80mm thick).
- The Benefit: Think of this as a winter coat for your water tank. It keeps your water hot for hours longer, so your boiler doesn't have to keep firing up just to give you a warm shower.
- EPC Impact: Can save roughly £40–£50 a year and adds immediate "points" to the heating efficiency section of the certificate.
- Estimated Cost: £20 – £35.
- DIY Difficulty: Easy (just wrap and tie).
3. Stop the Escape: Professional Draught Proofing
Assessors look for "primary" heat loss. Gaps in windows, doors, and even letterboxes allow cold air in and warm air out.
- The Fix: Use self-adhesive foam strips for windows and "brush" seals for the bottom of external doors. Don't forget a letterbox draught excluder.
- The Benefit: This stops that annoying cold breeze whistling under the front door or through window frames. It’s the fastest way to make a room feel "instantly warmer" without turning up the heating.
- EPC Impact: Improves the "Air Tightness" score of the dwelling.
- Estimated Cost: Starting from as little as £10.
- DIY Difficulty: Easy (peel-and-stick or simple screw-in strips).
Look to all-weather adhesives to help weather-proof and seal gaps around door frames, window sills or external cladding.
4. Control the Flow: Thermostatic Radiator Valves (TRVs)
An EPC assessor will check if you can control the temperature in individual rooms. If you only have a single central thermostat, you're missing out on points.
- The Fix: Replace standard manual radiator valves with Thermostatic Radiator Valves (TRVs).
- The Benefit: These give you total control over every room. Why pay to heat an empty guest room or a hallway to 21°C? Simply dial it down in rooms you aren't using and save a fortune.
- EPC Impact: High. Zoned heating is a key metric in the "Heating Controls" section of the assessment.
- Estimated Cost: £10–£20 per valve (a 4-pack often fits within a £60 budget).
- DIY Difficulty: Intermediate (requires basic plumbing; many tenants can ask their landlord to install them as a permanent upgrade).
Check out the extensive City Plumbing range of radiator valves & parts (like those from Drayton or Honeywell) for a reliable DIY-friendly upgrade.
5. Reflect the Heat: Radiator Foil Panels
For radiators on external walls, a significant amount of heat is actually used to warm your garden! Without a barrier, your bricks absorb the heat rather than the air in your room.
- The Fix: Slide radiator reflector panels behind your heaters. These act like a mirror, bouncing the infrared heat back into your living space where you actually need it.
- The Benefit: Your rooms will reach a comfortable temperature much faster, and your boiler won't have to work nearly as hard. It’s an "invisible" upgrade that makes a room feel instantly toastier.
- EPC Impact: While it’s considered a "supplementary" measure, it significantly boosts your home's efficiency score and shows an assessor that you are serious about heat retention.
- Estimated Cost: £15 – £30 per pack (enough for multiple radiators).
- DIY Difficulty: Very Easy (most designs simply clip onto the radiator brackets or stick to the wall—no plumbing required!).
