Meet the Monkeys
We got tired of clunky software, so we built our own. Five proper calculators and a live regs tracker — free in your browser, no sign-up, no nonsense.
ΨMonkey
Psi values
Model any junction and get its Ψ-value and fRsi temperature factor to BS EN ISO 10211 — free, no sign-up, no catch. Need it stamped for Building Control? A ready-to-submit PDF is £15 +VAT. Calculated psi values are often the cheapest route to a SAP 10 pass — so the maths can pay for itself.
WaterMonkey
Water Calculator
The full official water efficiency methodology, with live PASS/FAIL at 125 or 110 l/p/d as you type — rainwater & greywater included. PDF reports from £25 +VAT, and one dwelling type covers every identical plot on the site, so a whole estate needn’t cost the earth.
NutrientMonkey
Nutrient neutrality
Stuck behind a nutrient neutrality condition? Work out your nitrogen or phosphorus budget across all 27 Natural England catchments — the full NE methodology with the 20% buffer, free as you type. Planning-ready PDF reports are £79 +VAT.
SoakMonkey
Soakaways
Size a soakaway to BRE Digest 365 from your percolation test — four construction types, FSR rainfall and a climate-change uplift, all free in your browser. Building Control-ready PDF reports are £15 +VAT.
U-Monkey
U-values
Build up any wall, roof or floor and read its U-value live — to BS EN ISO 6946 and BR 443, with a self-drawing cross-section, Part L and Future Homes Standard checks and 200+ real UK products. Completely free, including PDFs – no sign-up, no catch.
Regs Radar What’s changing
The regs never sit still — Part L tweaks, Future Homes Standard dates, nutrient rules, credit prices. Regs Radar tracks the changes that actually affect your compliance work, in plain English, with email alerts when something moves.
How we make your life easier
We’ve seen it before
Over 20 years and hundreds of projects a year, big and small, across planning authorities nationwide. Your “unusual” condition is probably our Tuesday.
Advice, not just numbers
If a calculation fails, we don’t just shrug and send the bill. We model the options and point you at the cheapest practical route to a pass — we’ve built our own developments, so the advice comes from your side of the drawings.
Your All-in-one Energy Compliance Hub
SAP, EPC, water, air and sound under one roof, with the assumptions kept consistent so nothing contradicts itself — see the Compliance Pack.
