Year one starts around 11 p/kWh in Reading — well under the 21–25 p/kWh you pay to import. There is no capital outlay: a third party funds and maintains the system for 15–25 years and sells you the output. Around 50 kWp is the practical floor.

Thames Valley demand meets corporate net-zero pledges
Reading is the commercial heart of the Thames Valley tech corridor, and that shapes its appetite for power purchase agreements in a specific way. Data-centre operators and the UK offices of names such as SAP, Microsoft and Oracle carry both very high electricity demand and public net-zero commitments — a combination that makes contracted renewable supply attractive even where a company would never want solar assets on its own balance sheet. A PPA answers both: it delivers green, price-stable power while the developer owns and maintains the system. For firms whose demand outstrips their available roof, we also explain how virtual and sleeved PPA pricing works.
Business parks built for the model
Green Park, Thames Valley Park, Reading International Business Park and Worton Grange hold exactly the kind of large-floorplate corporate occupiers a funder likes to underwrite. The regional distribution network is run by Scottish and Southern Electricity Networks (SSEN), whose Southern licence covers Berkshire, so an early capacity conversation is worth having before sizing a rooftop or a car-park canopy. Occupiers in Wokingham, Bracknell, Henley-on-Thames and out toward Basingstoke sit within the same network area.
Where Reading's spend justifies it
Local commercial electricity bills average around £48,000 a year — above most UK cities — and for the data-heavy end of the market the true figure runs far higher. That scale is why a fraction-of-a-penny difference in the unit rate, or a poorly set annual escalator, translates into real money over a twenty-year term. Reading Borough Council's own 2030 climate strategy adds procurement pressure, but here the commercial driver leads. Weigh the routes on our side-by-side ownership comparison.
Independent scrutiny of every offer
We advise the buyer, never the developer, so we read the covenant tests, escalators and exit terms in the buyer's interest. See who is actively funding Thames Valley projects on our PPA provider directory.

PPA FAQs — Reading
What is a realistic year-one PPA rate for a Reading business?
Year-one tariffs in South East start around 11 p/kWh for well-matched sites. Size, off-taker covenant, contract length and the UK Power Networks + SSE connection all move it. Local commercial electricity spend averages about £48,000 a year, so the saving against 21–25 p/kWh grid import is what decides the case.
Which Reading sites are best suited to a PPA?
The strongest candidates sit on Green Park, Thames Valley Park, Reading International Business Park — large, unshaded roofs above steady weekday demand, which is the condition that makes on-site generation pay. Reading Borough Council works to its Reading 2030 Climate Strategy, which supports commercial PV locally.
Will the grid connection hold up a Reading project?
Reading sits in the UK Power Networks + SSE area. Export capacity is the usual constraint rather than the roof, and a G99 application typically runs 6–12 weeks, so start it early.
Do you cover Wokingham, Bracknell as well as Reading?
Yes — Wokingham, Bracknell, Henley-on-Thames and the wider South East draw on the same funder network and the same UK Power Networks + SSE region. That includes the RG1, RG2, RG4 postcode districts. If you hold more than one site in that area, aggregating them into a single sleeved deal normally beats negotiating each roof on its own.
How quickly can a site be generating?
Typically 6–12 months. Nothing about the paperwork is slow — the schedule is set by the connection application and the build window.
