How to Keep Track of a Home Renovation Project

The practical systems a UK homeowner needs to stay on top of budget, tasks, documents and contractor progress — from day one to sign-off.

What you actually need to track

A renovation has more moving parts than it looks like from the outside. Before you decide how to track things, it helps to know what "things" actually means.

Budget and costs

You need two numbers in your head at all times: what you have committed (signed quotes, purchase orders, materials on order) and what you have actually spent (paid invoices, receipts). The gap between the two is your outstanding liability. Most renovation overspends happen not because of one big surprise, but because small extras accumulate untracked — an extra skip hire, a change of tile specification, a day of additional labour.

A typical approach: write your total budget at the top of a page or spreadsheet, then subtract each committed cost as you sign a quote. Separately, mark items as paid when you settle the invoice. That way you always know both your maximum exposure and your current cashflow position.

Decisions

Renovations involve hundreds of choices — kitchen worktop material, tile grout colour, which socket positions you agreed with the electrician, whether the builder is fitting the lintels before or after the plasterer. The problem is not making the decisions; it is remembering them two weeks later when someone asks, or six months later when something goes wrong.

A simple decision log — even a running note on your phone — pays for itself the first time a contractor asks "what did you say you wanted?" and you can show them exactly what was agreed and when.

Documents

Some renovation documents are purely useful. Others are documents you will legally need to produce when you sell. These are not the same thing and it is worth being clear about the distinction.

Documents you will typically need to produce at resale include:

• Building Control completion certificate — issued by your local authority Building Control (LABC) or an approved inspector at the end of notifiable work (extensions, structural changes, loft conversions, new bathrooms). Without it, solicitors will flag the work as potentially unauthorised, which can stall a sale or require indemnity insurance.
• FENSA or CERTASS certificate — issued by a registered window and door installer, confirming the work complies with Building Regulations. If you replace windows or external doors without using a FENSA-registered company, you need to notify Building Control yourself.
• Gas Safe certificate — required for any gas installation or alteration. By law, this must be carried out by a Gas Safe registered engineer, who issues a certificate of compliance on completion.
• Electrical installation certificate — for notifiable electrical work (new circuits, consumer unit changes, work in kitchens or bathrooms). A registered electrician (NICEIC or NAPIT are the main certification bodies) self-certifies the work, or you notify Building Control.
• Planning permission decision notice — if your project required planning permission, keep the decision notice alongside the plans it was granted for.

Documents that are useful but not legally required at resale include contractor warranties, appliance guarantees, paint colours (Farrow & Ball reference numbers are worth noting), structural engineer's reports, and your own records of what was done and when.

Tasks

A task list for a renovation is not just a to-do list. It is the mechanism by which you track what each party — you, your main contractor, your tradespeople — is responsible for and whether it has been done. Without it, things fall through the gaps between contractors, each assuming the other has handled something.

Separate DIY tasks (things you are doing yourself) from professional tasks (things a contractor has been instructed and paid to do). Within professional tasks, it is worth noting which contractor is responsible, what the agreed price was, and whether the item is outstanding, in progress, or complete.

Notebook vs spreadsheet vs dedicated app

Notebook

Works well for decisions, daily notes and rough budget tracking. The main limitation is search — finding a note you made three weeks ago about a specific tile reference is tedious. Notebooks also don't survive a building site particularly well. Fine as a supplement; risky as your only system.

Spreadsheet

The most popular choice. A spreadsheet handles budget tracking well — you can build formulas, colour-code paid vs unpaid, and run totals automatically. The limitations: it doesn't do photos, it doesn't handle documents, and it requires discipline to maintain. Most spreadsheet-based renovation trackers get abandoned around month two when life gets busy. If you use a spreadsheet, keep it simple — complex formulas that you built and then forgot how to maintain are worse than a plain table.

A dedicated app

The appeal of a purpose-built tool is that it is designed around the specific shape of a renovation — quotes, certificates, tasks, contractors — rather than a general-purpose grid. The trade-off is learning a new tool. Whether that trade-off is worth it depends on the scale of your project. For a kitchen refit, a spreadsheet is probably fine. For a full extension or whole-house renovation, a dedicated tool earns its keep.

How RenoHub helps

RenoHub is an iPhone app built around exactly this problem: keeping a renovation in one place rather than scattered across a spreadsheet, a folder of PDFs, a WhatsApp thread and three different email chains.

The Task list is the core of the day-to-day. You can separate DIY tasks from professional work, add notes and photos, set priorities, and work through a clear checklist of what is done and what is outstanding. There is also an AI renovation advisor built in if you want a second opinion on anything — it uses your own OpenAI or Gemini key, stored in the iOS Keychain, and no data goes to RenoHub's servers.

Alongside tasks, the Document archive handles certificates and invoices — upload a photo of a Gas Safe certificate or a Building Control completion notice, and the AI pulls out the amount, supplier, and purpose automatically. Documents are stored on your device and in iCloud, not on any external server. The Project documents section is where you keep plans, renders, contractor contacts, and anything else specific to the project.

The Contractor Works Tracker is worth calling out specifically: import a contractor's PDF quote, and the AI extracts every line item into a live checklist. As work progresses, you tick off completed items and track spend against the original quoted price in real time — which is considerably more useful than cross-referencing a spreadsheet against a PDF at the end of each week.

RenoHub is currently free for life for anyone who downloads before 30 September 2026. After that it will be a one-off £4.99 — no subscription, no ads. It is iPhone only.
