Screen sites for grid and planning risk before you pay for surveys.
Say what you want to build: solar, battery storage, solar with a battery, or onshore wind. Site Finder ranks land across England, Scotland and Wales by grid headroom, planning record and project economics, so you know which sites deserve a visit and can show your investment committee why.
Platform from £30,000 a year Prices ex VAT. Order by email and pay by invoice.

What does Site Finder look like when you ask a question?
Load the app, read the verdict and scan the ranked list, then look across the map of scored sites. Names and figures are made up to show the interface.
Describe this animation
A question is typed: where should we build next? Chips show the project as 50 MWp, auto connection, CfD and a 6.5% hurdle. A verdict box says 8 of the top 20 sites are deliverable. A hex map fills in and a ranked list follows. Ellerstoke in Wendmoor needs £56.4 against a CfD price of £65.23, Kinlarrow in Glenmorvie needs £60.1, and Llanbedwyn in Dyffryn Cerwen needs £59.2. Numbered markers place the sites on the map. Names and figures are made up to show the interface.
Who uses Site Finder?
Developers, funds and landowners who need to decide where to spend time and money.
Developer land and origination teams
Find the sites most likely to connect and get consent, and take the shortlist to your investment committee with the evidence attached. Your team makes unlimited landowner checks and feasibility reports.
Funds and acquisition teams with their own analysts
Screen a seller's pipeline, track who holds the grid and follow changes, with the evidence behind every number and a seat for each analyst.
Site Finder narrows where to look. Your team still visits the land, talks to the network operator and takes planning advice.
What will I know about a site before I visit?
Every site opens into four answers you can take to a land agent, a network operator or your committee.
Can it connect?
The nearest substations, the headroom the network operator publishes, whether the site is likely to fit the current Gate 2 window, and who else already holds capacity there.
Will it get consent?
Schemes built, consented and refused nearby, how the local authority has decided similar applications, and the likely consent route for the size of your project.
Does it make money?
An indicative connection cost, the price per MWh the site needs to reach your hurdle rate, and how that moves when your assumptions change. For batteries, the break-even capex with and without the export credit.
Can we defend it?
A constraint checklist and the source behind every number. Any site can go into a feasibility report, a grid pack, an investment committee pack or an Excel model.
What can I do once I have a shortlist?
Keep working the shortlist: track each site to energisation, watch what other developers are doing and check a seller's claims.
Screen your own sites
Upload a boundary, a KML or a shapefile, or draw one on the map, and see how it compares with the ranked list.
Track every site to energisation
A pipeline board shows how firm each site's connection evidence is, from map only to energised, with reminders for Gate 2 milestones and land-rights deadlines.
See who holds the grid
A company group's projects and connections by technology, stage, substation and planning authority, plus Gate 2 positions with no planning application and connections that sit idle.
Hear about competitor moves
New connection applications, Gate changes, status moves and holder changes for the companies, substations and areas you watch, in the app and in a weekly email.
Check a seller's pipeline
Import a seller's site list and see each claim marked confirmed, contradicted, not verifiable or seller-supplied, with a data-room PDF and Excel workbook.
"Can I build here?"
Three guided checks: for a landowner approached by a developer, for a developer weighing one site, and for an investor testing a pipeline. Each ends with a one-page summary and questions for an adviser.
Know the rules
Dated cards on the consent route by nation and size, Gate 2 milestones and battery fire-safety guidance.
Feed your own tools and AI assistants
Through the data API and MCP server, your tools and assistants can read projects, substations, map cells, company holdings and changes.
What does Site Finder look like in use?
Animated scenes of the interface. The names and figures are made up to show how the tool works. They are not results for any project.
A working session
Ask the question and read the answer
Load the app, read the verdict and scan the ranked list, then look across the map of scored sites.
Describe this animation
A question is typed: where should we build next? Chips show the project as 50 MWp, auto connection, CfD and a 6.5% hurdle. A verdict box says 8 of the top 20 sites are deliverable. A hex map fills in and a ranked list follows. Ellerstoke in Wendmoor needs £56.4 against a CfD price of £65.23, Kinlarrow in Glenmorvie needs £60.1, and Llanbedwyn in Dyffryn Cerwen needs £59.2. Numbered markers place the sites on the map. Names and figures are made up to show the interface.
Open the evidence for a site
Open the top site: its score breakdown, substations, planning record and economics, then the one-page print pack.
Describe this animation
The top row, Ellerstoke in Wendmoor, is selected and an evidence drawer slides up. Six bars grow for grid, planning, solar and terrain, economics, deliverability and environment. Cards then show the nearest substation, Carrowby East Grid 33kV at 0.7 km with capacity ok, the planning record, and the economics: the site needs £56.4 against a CfD price of £65.23. Names and figures are made up to show the interface.
Push back and see what changed
Mark a substation as full and rescore, read the What changed card, then assume a Gate 2 offer and watch the answer move.
Describe this animation
Four ranked sites sit above a card for the substation Carrowby East Grid 33kV. Challenge is pressed, the substation is marked full, and a note says the operator has no spare capacity. After Rescore the rows move. Ellerstoke falls from first to fourth and the other three each rise one place. A What changed card lists each move and names the override as the cause. Names and figures are made up to show the interface.
Features up close
Gate 2 and grid headroom
See which sites can connect in the current window, then assume a Gate 2 offer and watch the ranking move.
Describe this animation
A bar shows 127.3 MW of Gate 2 solar capacity left in a zone. Three ranked sites of 38 MWac each take their share in rank order, and the figure falls to 89.3, 51.3 and then 13.3 MW. The fourth site, Daverby Magna, needs 36 MWac. It does not fit, so it moves to a box marked needs next window, with a later energisation year. Names and figures are made up to show the interface.
Planning record by local authority
Search the planning record by local authority for decisions, approval rates and recent schemes.
Describe this animation
A table lists local authorities, with a bar for the share of solar schemes approved. Saltmere is selected. Its panel says it approved 10 of 11 solar schemes since 2019, with a median decision time of 8 months, and a small chart shows decisions per year. A note says the rate is the authority's record and does not predict the outcome for a specific scheme. Names and figures are made up to show the interface.
Refused schemes nearby
A refused solar scheme near a site lowers its score, and the site's evidence names the scheme.
Describe this animation
A score waterfall for a site at Fennick Green in Callowfield starts at 0.84 before flags. Three multipliers follow: 0.91 for a refused scheme 1.7 km away, 0.94 for a National Park or AONB setting, and 0.92 for a listed building. The score ends at 0.66. A small map then shows the site, a dashed 1.7 km line and the refused scheme, Fallowmere Solar Farm, 34.5 MW. Names and figures are made up to show the interface.
Economics and project size
Take the project size past 100 MWac and watch the consent route, transmission charges and NPV change.
Describe this animation
A slider for project size moves from 90 to 110 MWac. As it passes 100 MWac the consent route changes from the local planning authority to the NSIP Development Consent Order route, and the NPV falls from +£7.6m to −£0.4m. A note names the size threshold and both values. Names and figures are made up to show the interface.
What if my team disagrees with the ranking?
Change what you believe about the market and the ranking follows, so the answer reflects your view.
Test your own assumptions
Change the technology, project size, revenue route, capex and hurdle rate. Draw areas on the map to include or exclude, or mark a single substation as full and note why.
See what moved and why
After each change, a card lists the sites that entered or left the top of the list, how far each moved and which assumption caused it.
Share the scenario
Save a set of assumptions under a name, compare two side by side and send one to a colleague as a link.

Site Finder screens sites. It does not replace a network operator's connection offer, planning advice or a site visit, and its connection costs are estimates for comparing sites. Where a network operator publishes no headroom, the site is marked unknown. Aerodrome and Ministry of Defence safeguarding is not assessed, so check it with the aerodrome operator, the MoD safeguarding team and, for wind, the NATS self-assessment maps before you commit. Coverage is Great Britain, and Site Finder does not show who owns a particular field.
Questions buyers ask about Site Finder
How does Site Finder help me find sites?
Tell it what you want to build and it ranks land across England, Scotland and Wales, with the grid, planning and economics behind each rank. Your team can spend survey money on sites that already look viable.
Which technologies and areas does it cover?
Solar, battery storage, solar with battery on a shared connection, and onshore wind, across Great Britain. Northern Ireland is not covered.
Does it replace a grid connection offer or planning advice?
No. It narrows where to look. Connection costs are indicative, so a network operator quote will differ, and planning advice, a site visit and aerodrome or Ministry of Defence checks still come before you commit.
Can it tell me whether a site can connect soon?
Where the network operator publishes a headroom figure, Site Finder shows it with its date, and where it does not, the site is marked unknown. It also shows who already holds capacity at the substation, and you can assume a Gate 2 offer and see how the ranking changes.
Can I test my own assumptions?
Yes. Change the technology, project size, revenue route, capex or hurdle rate, or mark a substation as full. The ranking updates and a card lists which sites moved and why.
How much does Site Finder cost?
The Site Finder platform is from £30,000 a year for 5 seats, excluding VAT, and your team makes unlimited landowner checks and feasibility reports. Enterprise terms for more seats, internal redistribution and named support are on quote. If you only need a single report, the landowner check (£195), the site feasibility report (£1,950 a site) and the portfolio screen (£7,500 for up to 50 sites) are sold on their own pages.
How do I order?
Press Order on the platform in the pricing section. Your email app opens a message to tarun@arithim.com with the details we need. We confirm the order by email and invoice after confirmation. Orders are subject to our terms, sent with the invoice.
Who is Site Finder for, and can I see a demo first?
Enterprise teams: developers and their land and origination teams, and funds and acquisition teams with their own analysts. Book a demo and we run Site Finder on a brief you choose: the technology, the project size, how you want to connect and the regions you care about. Landowners, first-time developers and consultants usually want one of the single reports instead.
