Tools we built, because we needed them.
Everything here started as a tool for our own survey and retrofit work — then grew into a product. Each one does a single job properly, from looking up an EPC to drawing a cavity-wall diagram to running a building firm’s books.
Built for our own assessment work first, then opened up. Every tool here is used on real surveys.
EPC Checker
Property & EPC lookup
Look up any UK address and read its EPC in full — rating, construction and fabric, heating and recommendations — in one view. Professionals get bulk lookups from a spreadsheet of addresses, saved properties and exports.
epc-checker.comFuture Forms
Survey form builder
Build the survey forms your team fills in on site. Made for UK retrofit assessment work: drafts transfer between surveyors mid-job, photos attach to answers, and a PAS 2035 template comes ready to use.

Retrofit job management
Run retrofit jobs end to end — jobs, documents and timelines for the whole team, with a finance view for admins covering expenses, invoices and the numbers behind the work.
Not publicly available — enquireCavwall
Cavity wall insulation diagrams
Draw to-scale cavity-wall elevation diagrams, place windows, doors and untreatable areas, and get treatable areas and POPT calculated live. Exports a clean, print-ready CWI survey PDF — and can auto-draft a whole property from its floor plans.
Not publicly available — enquireSolar Survey
Solar proposal creator
Roof-by-roof solar PV feasibility and array design, producing MCS-compliant yield figures ready for UK paperwork — with a full manual path for properties the mapping data doesn’t cover.
Not publicly available — enquireThe Graft line: the day-to-day running of a small business — work, money and records — in one simple app.
Graft
The builder’s business diary
One app instead of three: a job diary, a money tracker and a receipt box for building firms. Jobs, day notes, costs, takings and site photos — simple enough to use on site with gloves on.

Business records for any trade
Graft, generalised: sales, bookings, deliveries or jobs — whatever shape your work takes. Each business gets its own workspace, with tabs and language that match how it actually operates.
The professional tools are private.
The suite is in production and runs our own survey and retrofit work. It isn’t publicly available and there is no self-service sign-up — access is granted by us. If you’d like to know more, get in touch.
