Rules in. Results landed.
Pension calculations as a service, and the team that turns them into closed cases.
Send the deed, the benefit specification, the factor tables and the member data. Back comes every calculation in scope, coded from source and cited to its rule, its factor and the law. Then we close the questions, check the results and land them in your platform. Nothing to install. Nothing to maintain.

Every figure arrives like this. One number, its tranches, and the rule, the factor and the law behind each one.
You send. It runs. You receive.
At the centre is Diorama, the calculation and evidence engine built by our technology partner Pensionable.ai. It runs in the cloud. You never install it, host it or maintain it, and you never receive it. You receive what it produces, and the code to consume it. We carry everything either side of that: your material in, your results landed. One team, one plan, one number to call.

01 · You send
Your documents and data
The trust deed and rules, the benefit specification, the factor tables and the actuary's guidance, and member data when the phase calls for it. We assemble the sources, get the data ready and agree scope by calculation family.
-
02 · It runs
In the cloud, never on your estate
The scheme's basis is built from source. Every member is computed on every basis, and every figure carries its rule, its factor and the law behind it. Where a calculation cannot be supported, it is refused, with the reason.

Eight things, landed
Every member's values with the audit trail, the scheme report, the searchable rules, the questions list, the check to the penny, the documents and the adapter into your platform. We close the questions, check the results and land them.
Nothing to install
No software on your estate, no environment to stand up, no build machinery to inherit. The run is the service.
Nothing to maintain
The basis is kept current as revaluation orders and amendments land. You consume outputs, not a codebase.
Nothing to guess
Every figure names its rule, its factor and the law. Every ambiguity becomes a numbered question with the reading taken. Where it cannot compute, it says no.
Eight things, every scheme.
The same eight deliverables come back for every scheme. Each one starts a piece of work on your side of the line, and that work is ours to carry. The left column is what comes out. The right is what we do with it.
Member values grid
Every member, every basis, in a workbook. Zeros are answers too.
Loaded or compared into your platform, exceptions worked, control totals reconciled.
Audit trail
Every figure traced to its rule, its factor and the law it rests on.
A checker reviews inputs, rule and factor before release, and the review is recorded.
Scheme report
How the scheme works, how the figures were produced, and what was assumed.
Trustee and scheme actuary sign-off run to a decision log. The report becomes the basis of record.
Searchable rules
The scheme's rules as a structured, searchable record, every clause cited.
Adopted as the golden source, kept current as amendments land, your administrators trained on it.
Check against your current figures
To the penny, with every difference listed and explained rather than reconciled away.
Each difference investigated, the affected population sized, the remediation run to a close.
Questions list
Every ambiguity, numbered, with the reading taken and what would change it.
Evidence assembled per question, the decision taken by your actuary or trustees, the answer recorded, the run repeated.
Member documents
Letters and statements written from the same run. Nobody types the number.
Templates agreed, dispatch controlled, member communications and calls handled.
Integration code
A file, an interface or an adapter that writes results into your platform's fields.
Field mapping on your side, user acceptance testing, change control, parallel run, cut-over.
The truth of the scheme, computed. The outcome, delivered.
Eight ways to start.
Most schemes come to us with one pressing problem, then keep going. Every engagement below starts with the same scheme build and the same team shape, and ends with something you hold. If a UK defined benefit scheme has to do it, it is in scope.
-
01
Backlog clearance
Cases waiting on a quote or a settlement. The scheme's basis is built once, the queue is run in bulk with per-member evidence, and our case handlers work the exceptions inside your process. Weekly batches, measured in cases per day.
You hold: a cleared queue, each case with its audit trail, and an evidence pack for the auditor. -
02
Scheme implementation and migration
A scheme arriving from another administrator, or moving platform. The certified basis, values and test cases become the golden source for testing. A parallel run against the outgoing figures explains every difference, and the move of authority is staged with the route back proven at each step.
You hold: a scheme live on your platform with fewer defects after go-live, and an independent truth to regress against. -
03
Calculation assurance and rectification
Is what your platform quotes and pays right? Recomputed from source, compared to the penny, every difference with its cause. Then the rectification: recalculations, back-payments, member communications, trustee and regulator reporting.
You hold: a defended calculation basis, a closed rectification, and the record of both. -
04
GMP equalisation and historic errors
The tangled ones. Equalisation, revaluation, anti-franking, and the amendments nobody can reconcile, computed with citations and a numbered questions list, then investigated, sized and put right. Decided and closed, not flagged.
You hold: an equalised basis with its evidence, and redress delivered to the members it touched. -
05
Calculation automation
Manual and spreadsheet calculations turned into coded, cited, tested ones that run on demand through an interface and write into your platform's fields. Scoped with your calculation team, with test packs, acceptance testing, change control and training.
You hold: calculations that run with evidence, in place of an internal build programme. -
06
Buy-in and buy-out readiness
An insurer-grade benefit specification cited to source, member values on the insurer's basis, and the data gaps ranked by what they block and fixed. The data room built and run, insurer questions answered, all managed to the transaction date.
You hold: a specification and a data set an insurer can price, with the evidence behind each. -
07
Pensions dashboards
Value data is calculation data. Accrued and projected values computed to the scheme's own rules for every member, matched and tested, then landed with your dashboards connection so the figure a member sees is the figure the scheme would pay. The connection deadline is 31 October 2026.
You hold: value data you can defend, member by member, and a connection that holds. -
08
Data readiness
The basis defines which fields each calculation needs for each member category. Gaps are found and ranked by what they block, resolved as costed batches, and every fix evidenced. A clean base for any of the above, or for the next thing.
You hold: data the calculations can run on, with a record of what changed and why.
Where your data goes, and where it does not.
Security is the first filter, not the last. So the work is phased around it, and your security review runs alongside the pilot rather than in front of it.
No member data leaves you
Documents, the benefit specification, and your own test cases or synthetic members. The comparison runs against the figures you have saved. Everything the engine needs to build and prove the basis, and nothing personal.
A pseudonymised extract, under agreement
The bulk run uses an extract with identity removed, under a data processing agreement and an impact assessment, held to the controls your security team agrees, and deleted on completion with confirmation.
No model in the calculation path
Models read scheme documents to build the basis. Member figures come from deterministic code, so the same inputs give the same outputs every time, and every figure can be replayed to its source.
Your people keep the decisions
The checker, the scheme actuary and the trustees decide. We add capacity under your controls, with named individuals per engagement and access removed at exit.
You own every deliverable. The values, the report, the searchable rules and the adapters work without the engine. We carry delivery continuity. Pensionable.ai publishes its own account of how the engine is built and tested.
Read Pensionable.ai's trust and safety briefThe people who land it.
An engine finds and builds. People still have to get the material in, answer the questions it raises, check what comes back, put it safely into live administration and take every case to a decided outcome. That is where the months go, and it is what we carry.
Named owners
One accountable owner for the scheme, one plan, and a decision log that records who decided what and when.
Inside your process
Checking, investigation and landing happen under your controls and in your platform, so the evidence is yours and your sign-off stays yours.
Flexes with the work
Heavy through build and checking, light once it settles. You fund the work in front of you, not a standing team between projects.
Behind it, a bench of over 250 pensions practitioners built over twenty years of pensions-only work, each one known by what they have delivered rather than by a CV.
Start with one scheme.
Six weeks, fixed price, on one scheme or one backlog slice. Phase one on documents, the benefit specification and test cases, with no live member data leaving you. Phase two on a pseudonymised extract under agreement. A named team, acceptance criteria agreed up front, and the fee credited against the full engagement. You decide after that.
- An evidence pack the auditor can read, figure by figure.
- The questions closed, each with the decision and who took it.
- Results landed in your platform, or a costed plan to land them.
- A straight answer on who does the work, how long it takes and what it costs.
Point it at something that matters: a scheme, a backlog or a deadline. We would rather be tested than taken on trust, so bring the hard one.
