Energy & RetrofitSpray Foam Insulation: Advantages, Disadvantages, and Installation Considerations
Spray foam insulation delivers excellent thermal performance and air sealing but carries significant risks in UK homes, particularly when applied to roof timbers — it can trap moisture, cause structural damage, and make properties harder to mortgage or sell. Professional assessment and an accredited installer are essential before choosing spray foam.
Energy & RetrofitProfessional solar panel inspection: what to expect and why it matters
A professional solar panel inspection typically takes 1–3 hours and covers visual panel condition, mounting hardware, inverter performance, wiring integrity, and often thermal imaging to detect hidden faults. You receive a written report with findings and recommendations. It is worth arranging before selling a property, if output has dropped unexpectedly, or if the system is over five years old.
Energy & RetrofitRoof Ventilation Installation and Considerations
Roof ventilation prevents condensation, rot, and structural damage in UK roof spaces by maintaining airflow above insulation. Approved Document F specifies minimum free air areas at eaves and ridge level for cold-roof constructions. Retrofit improvements such as additional loft insulation can worsen moisture risk if ventilation is not assessed and upgraded at the same time, particularly under PAS 2035.
Energy & RetrofitGarage Insulation Installation: Costs And Options
Garage insulation costs and methods depend on whether you are converting to habitable space or improving a working garage. Rigid PIR boards offer the highest performance per millimetre, while mineral wool batts are a lower-cost alternative. A full walls-and-roof treatment for an 18 m² garage typically costs £1,500–£3,500. Building Regulations approval is required for any habitable conversion.
Energy & RetrofitSolar Panel Installation: Home Energy Generation Investment
Solar panel installation in the UK typically costs £5,000–£9,000 for a 3–4 kWp system. Most homes need a solar survey to confirm roof suitability, shading, and structural condition. Only MCS-certified installations qualify for the Smart Export Guarantee, which pays for surplus electricity exported to the grid.
Energy & RetrofitFireplace Draught Prevention: Sealing and Efficiency Solutions
Draughts from fireplaces and chimneys are a significant source of heat loss in UK homes, particularly in Victorian and Edwardian properties. Chimney balloons and draught excluders reduce heat loss from unused fireplaces at low cost. Sealing a flue connected to any live appliance must only be carried out by a Gas Safe or HETAS-registered engineer to avoid carbon monoxide risk.
Energy & RetrofitSolar Panel Leasing vs. Ownership: Comparing Your Options
In the UK, owning your solar panels — whether purchased outright or via a loan — entitles you to all income under the Smart Export Guarantee (SEG). A lease or rent-a-roof arrangement typically means the solar company retains SEG payments, and the lease can complicate your property sale or remortgage. Most homeowners benefit more financially from ownership if they can fund it.
Energy & RetrofitHome Ventilation Solutions and Air Quality Management
The right home ventilation solution depends on how airtight and well-insulated your property is. Extract fans and trickle vents suit older, leakier homes; MVHR is better suited to airtight, well-insulated properties. If condensation or mould has worsened after insulation work, a ventilation assessment under PAS 2035 should be your starting point.
Energy & RetrofitComparing skylights with solar tube lighting systems for natural illumination
Skylights deliver more light and ventilation but involve more structural work, may need planning permission, and typically cost more. Solar tubes (tubular daylighting devices) are faster to install, work in rooms not directly below the roof, and often fall under permitted development, but are sealed units that provide no ventilation. The right choice depends on the room, roof type, and budget.
Energy & RetrofitMechanical Ventilation with Heat Recovery System Costs
A whole-house MVHR system typically costs £3,000–£8,000 supplied and installed in a UK home, rising to £10,000 or more for larger or complex properties. The unit, ductwork design, property size, airtightness level, and installer qualifications all affect the final price. Annual servicing adds around £150–£300 per year on top.
Energy & RetrofitHome Wind Turbine Installation: Costs and Feasibility
A domestic wind turbine is only cost-effective if your site averages 5–6 metres per second or more in wind speed. Pole-mounted turbines (2.5–6kW) cost £15,000–£25,000 installed; roof-mounted micro-turbines are cheaper but generate far less electricity. MCS certification is required to access Smart Export Guarantee payments. Always commission a site assessment before purchasing equipment.
Energy & RetrofitSolar-powered air conditioning systems: suitability and energy benefits
Solar-powered air conditioning pairs photovoltaic panels with an inverter-driven air conditioning unit to cool a home using renewable electricity. In UK conditions, a hybrid solar-plus-grid system is more practical than fully off-grid cooling. Energy savings of £80–£250 per year on cooling costs are typical, though a qualified assessor should size the system correctly for your roof and usage pattern.
