Making British Homes Energy Efficient
We help homeowners across the UK reduce energy consumption, lower bills, and create comfortable, sustainable living spaces through expert assessments and tailored improvement strategies.
Explore Our ServicesWhy Energy Efficiency Matters Now
Energy costs continue to climb across the United Kingdom, and homeowners face increasing pressure to reduce consumption while maintaining comfort. The average British household loses hundreds of pounds annually through inefficient heating, poor insulation, and outdated systems. Beyond the financial impact, every unit of wasted energy contributes to environmental challenges we can no longer ignore.
calm-funds exists to bridge the gap between intention and action. We work with homeowners who recognize the need for change but aren't sure where to begin. Our approach combines technical expertise with practical understanding of how people actually live in their homes.
Our Core Services
Comprehensive Home Energy Assessments
Detailed thermal imaging, air leakage testing, and system evaluation to identify exactly where your home loses energy and money.
Insulation Solutions
From loft and cavity walls to solid wall insulation, we recommend and oversee installations that dramatically reduce heat loss.
Heating System Optimization
Upgrade to modern condensing boilers, heat pumps, or optimize your existing system for maximum efficiency and comfort.
Renewable Energy Integration
Solar panels, battery storage, and renewable heating systems designed to work with your home and lifestyle.
Our Philosophy
We believe effective energy efficiency starts with understanding, not selling. Too many homeowners have been misled by one-size-fits-all solutions that promise savings but fail to deliver. Every property is different. A Victorian terrace faces different challenges than a 1970s semi-detached or a modern flat.
Our team takes time to understand how you use your space, what matters most to you, and what your budget allows. We then create a prioritized plan that addresses the most impactful improvements first. Sometimes that means starting with simple draught-proofing. Other times it means a complete heating system overhaul. We let the evidence guide our recommendations.
Transparency matters to us. We explain what each improvement will cost, how much you'll save, and how long the payback period will be. No inflated promises, no pressure tactics.
Impact We've Created
How We Work
Initial Consultation
We discuss your concerns, bills, comfort issues, and goals. This conversation helps us understand what success looks like for you.
Comprehensive Assessment
Our certified assessors visit your property with thermal cameras, air testing equipment, and decades of experience. We examine every aspect of your home's energy performance.
Custom Strategy
We present a detailed report with thermal images, findings, and a prioritized action plan. Each recommendation includes cost estimates and projected savings.
Implementation Support
Whether you choose to work with our trusted contractors or your own, we provide technical oversight to ensure work meets specifications and achieves intended results.
Verification & Follow-up
Post-installation testing confirms improvements are working as designed. We provide guidance on optimizing your upgraded systems and remain available for questions.
What Homeowners Say
"We were spending over £2,000 a year heating our 1930s semi and still felt cold. calm-funds identified the issues - poor loft insulation, draughty windows, and an oversized boiler cycling constantly. Six months after following their plan, our bills are down 40% and the house finally feels warm."
"I'd been considering solar panels for years but wasn't sure if they made sense for my roof orientation. The team did a proper analysis including shading, predicted generation, and realistic payback calculations. Turns out my roof was ideal. Panels went in last spring and they're generating more than projected."
"As first-time buyers, we knew our Victorian flat needed work but had no idea where to start. The assessment revealed the single-glazed windows weren't actually the biggest problem - it was the suspended timber floors with no insulation. That insight completely changed our renovation priorities and saved us from wasting money on the wrong upgrades."
Properties We Serve
Period Properties
Victorian and Edwardian homes require specialized approaches that respect original features while dramatically improving efficiency. We understand solid walls, sash windows, and heritage constraints.
Post-War Housing
Properties built between 1945-1980 often have cavity walls perfect for insulation and heating systems ready for upgrades. These homes respond exceptionally well to targeted improvements.
Modern Homes
Even newer properties can benefit from optimization, renewable integration, and smart system controls that maximize efficiency and comfort.
Flats & Apartments
Unique challenges with shared walls, communal systems, and leasehold restrictions require specialized knowledge and creative solutions.
Understanding Energy Efficiency
The Real Cost of Inefficiency
Most British homes waste 20-40% of the energy they consume. That's not just money disappearing into the atmosphere - it's environmental impact that could be avoided and comfort that could be improved. An uninsulated loft loses as much heat as leaving a window open all winter. Single-glazed windows can account for 25% of heat loss. A poorly maintained boiler might be operating at 60% efficiency when modern systems achieve 90% or higher.
Where to Start
The most impactful improvements often aren't the most expensive. Proper loft insulation costs relatively little but can cut heat loss through your roof by 75%. Draught-proofing doors and windows might cost under £100 but eliminates cold spots and reduces heating demand. Understanding your specific situation is crucial - we've seen homeowners spend thousands on new windows when their actual problem was an incorrectly installed heating system.
Government Support
Various schemes offer grants and low-interest loans for energy efficiency improvements. Eligibility depends on property type, income, existing efficiency rating, and improvement type. We help navigate these programs and identify what you qualify for, potentially reducing your out-of-pocket costs significantly.
Common Questions
Savings depend entirely on your starting point and which improvements you implement. A typical uninsulated home might save £300-600 annually from loft and cavity wall insulation. Upgrading an old boiler to a modern condensing model can save £200-400 per year. Comprehensive improvements on poorly performing properties sometimes achieve 50% reductions. We provide specific estimates based on your actual property after assessment.
Generally, reduce heat loss before upgrading heat generation. Insulating first means you need less heating capacity, allowing you to install a smaller, more efficient, less expensive system. If your boiler is broken and needs immediate replacement, that changes the equation. Our assessment identifies the optimal sequence for your situation.
Heat pumps work best in well-insulated properties with adequate radiator capacity or underfloor heating. Many older homes can be adapted, but it requires careful planning. We assess whether your property is heat-pump ready or what improvements would be needed first. For some period properties, a modern condensing boiler might be more practical and cost-effective.
Insulation typically lasts 40+ years with no maintenance. Double glazing lasts 20-25 years. Modern boilers have 10-15 year lifespans. Solar panels generally come with 25-year performance warranties. These are long-term investments that continue delivering savings year after year.
Energy efficiency is increasingly important to buyers. A better EPC rating makes your property more attractive and can influence value, particularly as energy costs remain high. Beyond market value, improvements enhance comfort and liveability, making your home more enjoyable while you're in it.
