Showing 20 of 21 guidesHome Energy Grants & Support Explained
• Several government-backed schemes help fund insulation and heating upgrades • Eligibility often depends on income, benefits or EPC rating • Energy suppliers must deliver funding under the ECO scheme • Additional support exists for households in fuel poverty • Always apply through official or accredited channels
Deep DiveHow Energy Markets Actually Work
• Energy is traded in wholesale markets before reaching suppliers • Gas often sets electricity prices in the UK • Suppliers hedge energy months or years ahead • Network costs are regulated and form part of your bill • Global events heavily influence UK prices • Ofgem regulates suppliers and the Energy Price Cap
Support & RightsEnergy Supply for Park Homes Explained
• Many park homes receive energy via site owner resale • Maximum resale price rules apply • Residents may not be able to switch supplier • Ofgem protections differ from standard domestic supply
Deep DiveDistrict Heating Explained
• Heat generated centrally and distributed to multiple homes • No individual gas boiler • Pricing may differ from standard gas supply • Consumer protections evolving • Heat network regulation increasing
Support & RightsPriority Services Register Explained
• Free support for vulnerable energy customers • Available through suppliers and network operators • Includes outage support, accessible communications and safety services • Covers temporary and long-term vulnerability • You can register at any time
Deep DiveOut-of-Contract Rates Explained
• Out-of-contract rates are significantly higher energy prices applied when a business contract expires without renewal, making it crucial to secure a new deal promptly to avoid substantial, unnecessary costs.
Core GuideRenewable Energy for Your Home
• Solar panels generate electricity and reduce grid purchases • Home batteries increase self-consumption and flexibility • Heat pumps replace gas boilers with electric heating • Green tariffs vary in structure and impact • Government grants can reduce upfront costs • Payback depends on usage patterns, not just system size
Key GuideSwitching Energy Suppliers: A Simple How-To Guide
• Switching is administrative only — supply is never interrupted • Most switches complete in around five working days (after cooling-off) • You have a 14-day cooling-off period • Exit fees may apply on fixed tariffs • You can switch penalty-free within 49 days of contract end • Smart meters usually remain fully functional • Final bills must be issued within six weeks
Core GuideEV Charging at Home Explained
• Home charging is usually cheaper than public rapid charging • Most homes install a 7kW wallbox charger • Off-peak EV tariffs can significantly reduce running costs • Installation may require electrical assessment • Smart charging regulations apply to new chargers
Key GuideUnderstanding Your Energy Bill
• Bills are calculated using kWh usage • Unit rate × consumption = usage cost • Standing charge applies daily • VAT is 5% for domestic supply • Direct debit smooths seasonal variation
Core GuideEnergy Saving Tips for Your Home
• Heating efficiency usually delivers the biggest savings • Small behavioural changes can compound over time • Insulation reduces demand permanently • Appliance efficiency matters over the long term • Measurement is essential — guesswork leads to poor decisions
Key GuideEnergy Price Cap Explained
• The cap limits unit rates and standing charges • It applies to standard variable tariffs • It is updated quarterly • It reflects wholesale and network costs • It does not cap total household bills
Key GuideFixed vs Variable Tariffs Explained
• Fixed tariffs lock your unit rate for a set period • Variable tariffs can rise or fall with market changes • The Energy Price Cap limits most standard variable tariffs • Fixed tariffs often include exit fees • The best choice depends on risk tolerance and market conditions
Core GuideReducing Home Energy Consumption
• Fabric-first retrofit reduces demand permanently • Efficient heating systems depend on insulation • Measurement enables optimisation • Electrification requires demand reduction first • Sequencing matters for cost-effectiveness
Key GuideWhat Affects Energy Prices?
• Wholesale gas prices heavily influence UK electricity prices • Global events directly impact UK household bills • Suppliers hedge energy in advance to manage risk • Network and policy costs form a significant share of bills • Weather and demand volatility can shift prices rapidly • The Energy Price Cap limits retail pricing but does not control wholesale markets
Core GuideSolar Panels Explained
Solar panels generate electricity from daylight and can reduce your reliance on grid power. The financial benefit comes mainly from using the electricity you produce yourself, rather than exporting surplus to the grid. Most UK homes install systems between 3kW and 5kW, with installation costs commonly ranging from £5,000 to £8,000. Savings depend heavily on roof suitability, shading, electricity usage patterns and whether you add battery storage. Solar works best when you can use more power during daylight hours. Export payments under the Smart Export Guarantee are available but are usually modest compared to the value of self-consumption. Panels typically last 25+ years, while inverters may need replacement after 10–15 years. Installer certification and proper documentation are essential for export eligibility.
Key GuideUnderstanding Smart Meters
• Smart meters send readings automatically • Bills are based on actual usage • They do not automatically reduce bills • You can decline installation • Data privacy is regulated
Core GuideHeat Pumps Explained
• Heat pumps move heat rather than generate it • They work best in well-insulated homes • Flow temperatures are lower than gas boilers • Boiler Upgrade Scheme grants may be available • Installation quality is critical
Core GuideUnderstanding EPCs
• EPC ratings range from A to G • Required when selling or renting • Based on standardised modelling • Includes recommended improvements • Landlords face minimum rating rules
Core GuideHome Batteries Explained
• Batteries store electricity for later use • Most common with solar panels • Can increase self-consumption • Expensive upfront • May benefit from time-of-use tariffs
