We work for residential developers and their main contractors as the specialist subcontractor for the electrical, mechanical and renewables package, from the incoming supply to the solar array on the roof. For more than a decade our team has completed the installations in 30 to 40 apartments every year, on programme and fully certified. We also design, install and look after complete renewable-energy systems for homes, businesses and community organisations.
Raf Ski Construction is a specialist electrical and M&E subcontractor. We do not build or sell homes ourselves: we install the building services on residential new builds for developers and main contractors. We have been registered with NICEIC as an Approved Contractor for 18 years, and every installation we hand over is designed, installed, inspected and certified to BS 7671.
For the past ten years we have completed the installations in between 30 and 40 apartments a year for a core group of developers who return to us scheme after scheme. That steady, repeat workload is how we measure ourselves: if a client trusts us with the next phase, we did the last one properly.
Because we cover the electrical, mechanical, controls, life-safety and renewables packages under one roof, developers and main contractors deal with a single team, a single programme and a single set of handover documents.
Each package can be priced on its own or combined into a full building-services contract. Combining them removes the gaps between trades, which is where most delays and snagging on new builds come from.
The complete electrical package for apartment blocks and housing schemes, from the incoming supply through to final certification.
Zoned, app-controlled heating for each apartment, designed to cut energy use and give residents simple control from a wall thermostat or their phone.
A building management system gives the client one view of the whole building. We install and commission systems that monitor and control plant, ventilation, lighting and energy use across communal areas.
Smoke control and fire detection are among the most scrutinised parts of any residential block. We install and commission them so they pass inspection first time and stay easy to maintain.
Roof-mounted photovoltaic systems sized to the building and its energy targets. Solar is now central to meeting Part L and the Future Homes Standard, and we cover it in detail below.
Hybrid inverters and battery storage that keep solar generation in the building for use in the evening, lowering bills for residents and landlord supplies. More below.
Hot and cold water, heating and drainage installations for new buildings, coordinated with the electrical and controls packages so plant, wiring and pipework go in once and in the right order.
New homes in England are now expected to produce far less carbon than they did a few years ago, and on-site renewable generation is one of the most reliable ways to get there. A well-designed solar PV system, paired with battery storage, reduces running costs for residents, helps the scheme meet Part L and SAP targets, and adds real value at sale.
We design, install and commission complete systems for apartment blocks and housing developments, and because we are also the electrical contractor, the PV is integrated with the building's distribution from day one rather than bolted on at the end.
We assess the roof area, orientation and shading, then size the array to the building's demand and the energy strategy. Layouts are coordinated with the architect, the structural engineer and the roofing contractor.
We prepare the paperwork for the local network operator, including G98 or G99 applications, so the system can be connected and export surplus energy legally and without delay.
Mounting systems for flat and pitched roofs, DC cabling, isolators, inverters and generation metering, installed alongside the rest of the electrical package.
Hybrid inverters and batteries store daytime generation for evening use. Systems can serve landlord supplies, individual apartments or both, depending on the scheme.
Every system is tested, commissioned and certified, with monitoring set up and full documentation for the developer, the managing agent and building control.
On-site generation is one of the most cost-effective ways to hit tighter carbon and primary energy targets in SAP calculations.
Free daytime electricity, and with a battery, cheaper evenings too. Low running costs are a strong selling point for buyers and tenants.
Solar on landlord circuits reduces the cost of lifts, lighting and plant, which keeps service charges down.
Renewables improve the energy rating of every unit, supporting sales values and mortgage lending.
Alongside our work for developers, Raf Ski Construction Ltd designs, installs and looks after complete renewable-energy systems. We do more than fit solar panels: we assess how you use energy, design the right combination of solar, storage and smart controls, install it to the required standards, and stay responsible for how it performs afterwards.
Our aim is simple: to make renewable energy practical, affordable and measurable, with systems that cut energy costs, increase your independence from the grid and support the move to low-carbon energy.
A single point of contact from your first energy assessment through installation and aftercare.
Technology chosen for your actual consumption, not a one-size-fits-all package.
Equipment, labour, assumptions, warranties and expected performance all set out in writing.
Careful installation, documented commissioning and a proper handover.
Ongoing monitoring and maintenance once your system is running.
Rooftop solar for homes and commercial buildings: design, supply, installation management, commissioning and monitoring.
Batteries sized to help you use more of your own solar, cut costly peak-time imports and, where it makes commercial sense, optimise export.
Smart monitoring, load management and practical advice to move your electricity use to times of higher solar generation or cheaper tariffs.
Electric-vehicle chargers integrated with your solar and battery system, installed to the relevant electrical and regulatory requirements.
Energy-use assessments, then recommending or installing the right measures, such as efficient lighting, heating controls and ventilation.
Heat pumps integrated with solar PV, batteries and smart controls as one system, working with qualified specialist partners where required.
Feasibility studies and delivery for offices, warehouses, schools, community buildings and other larger sites.
Remote monitoring, fault response, inspections, panel cleaning where appropriate, warranty coordination and performance reviews.
We design every solar and battery system in the same order. It stops equipment being oversized just to generate more, and makes sure your money goes where it saves the most.
