New-build estate covenants: when your deeds say the garage stays a garage
The most common nasty surprise in this trade is a paragraph in your deeds. Thousands of new-build homes carry covenants restricting garage use. Planning permission does not override them. Most builders never mention it. This guide covers checking, consent and consequences.
Can a restrictive covenant stop a garage conversion?
Yes — even one that planning law fully allows. A restrictive covenant is a private legal obligation attached to your property's title, enforceable by whoever holds its benefit (usually the developer or a management company). Planning permission and permitted development rights operate in a completely separate system and do not override it.
This separation is the trap. A homeowner checks the planning position, correctly concludes no application is needed, converts — and is still in breach of covenant. The three systems (planning, building regulations, and private covenants) are independent; a clean conversion clears all three.
Why do new estates have garage covenants?
Sales control, mostly. While a developer is still selling an estate, covenants let it keep the street scene tidy and the parking picture intact — a road full of converted garages and pavement-parked cars sells fewer plots. Common covenant wordings: the garage may only be used for "parking of private motor vehicles", or alterations require the developer's written consent.
Understanding the motive matters because it predicts the outcome: once the estate is sold out, the developer's commercial interest in your garage evaporates. That's why consent applications for well-designed conversions — especially ones that keep off-street parking on the driveway — succeed far more often than internet forums fear. The covenant is usually a toll booth, not a wall.
Which Aylesbury estates are affected?
Assume any estate built since the late 1990s might be — plot by plot. Around Aylesbury, homes on Kingsbrook, Berryfields, Buckingham Park, Fairford Leys and similar developments commonly carry garage or alteration covenants, but wording varies between developers, phases and even neighbouring plots. Your title register — not your neighbour's experience — is the only reliable answer.
Two local wrinkles worth knowing. First, several of these estates also have management companies collecting estate charges; where the covenant's benefit has passed to the management company, that's who you apply to, not the original housebuilder. Second, new-build covenants often ride alongside planning conditions requiring garage parking (a separate hurdle in the planning system) — the same estate can have both, which is why our survey checks the planning portal and the title register together.
How do you check your deeds for a covenant?
Order your title register from HM Land Registry — £7, online, ten minutes. Covenants appear in the Charges Register (section C), usually referring to a transfer deed (TP1) which contains the full wording. If the register references a deed you don't hold, order that too. Look for restrictions on garage use, alterations, and requirements for consent.
- Search HM Land Registry for your address and download the title register (£7) and title plan.
- Read section C (Charges Register) for entries beginning "The land is subject to the following restrictive covenants…" — garage covenants typically restrict use to vehicle parking, or require written consent for alterations, or both.
- Order the referenced deed (often the original TP1 transfer) if the register summarises rather than quotes — the exact wording decides everything, including whether a half-conversion keeping one parking bay would technically comply.
- Check the covenant's beneficiary: the developer named may have sold the benefit to a management company, or ceased to exist — both change the consent route below.
We do this check, at our cost, for every survey we carry out. If reading legalistic deed wording isn't your idea of an evening, that's the shortcut: book the survey and bring us the paperwork.
How do you get consent to convert?
Apply in writing to whoever holds the covenant's benefit. Most volume housebuilders have a standard alterations-consent process: a form or letter, your drawings, and an administration fee — typically £50–£500. Well-designed conversions that keep driveway parking and match the house's external appearance are routinely approved, usually within a few weeks.
| Situation | Route | Typical cost & time |
|---|---|---|
| Developer still active, holds benefit | Alterations consent application with drawings | £50–£500 · 2–8 weeks |
| Benefit passed to management company | Same application, addressed to the managing agent | £75–£400 · 2–8 weeks |
| Beneficiary defunct or untraceable | Indemnity insurance at point of works or sale | £150–£400 one-off premium |
| Consent refused or terms unreasonable | Negotiate a deed of release, or apply to the Upper Tribunal (Lands Chamber) to modify/discharge | £1,000s · months — rare for garages |
Practical tips that improve approval odds: apply before work starts (retrospective requests invite harder bargaining); include drawings showing the matched brickwork and window design; state explicitly that driveway parking remains; and if your deed's wording is about parking provision rather than the garage structure, point out how the proposal preserves it. Our drawings are written with the consent audience in mind as well as building control.
What happens if you convert without consent?
Nothing dramatic on day one — the bill arrives when you sell. Your buyer's solicitor will spot the covenant and the conversion, and will require either retrospective consent, an indemnity policy, or a price adjustment. In the worst (rare) case, a beneficiary with standing could seek an injunction or damages. Breaches don't expire quickly; the problem waits.
The realistic risk picture: enforcement during your ownership is uncommon — developers rarely patrol sold-out estates, and a management company needs both standing and appetite. The near-certain cost is transactional: every future sale of the house now includes a conversation about the breach, resolved either by indemnity insurance (£150–£400, but only available if the beneficiary hasn't been alerted — asking for consent after converting can void your eligibility) or by retrospective consent negotiated from a weak position.
One more honest note: an indemnity policy insures against enforcement costs. It doesn't make the conversion compliant, and a cautious buyer — or their lender — can still walk. Consent beforehand is cheaper than every alternative that follows skipping it. This is the whole reason we check covenants before quoting rather than treating them as the homeowner's problem: a conversion that can't be sold cleanly isn't finished, whatever it looks like.
Covenant questions
Does a half-conversion get around a parking covenant?
Sometimes — it depends on the exact wording. A covenant requiring "a garage available for parking" may be satisfied by keeping one bay of a double; one restricting any alteration still needs consent. Either way, proposing a half-conversion usually makes the consent conversation easier. See the double garage page for how half-conversions work.
My house is 20 years old. Do covenants expire?
Restrictive covenants don't expire with time — some Victorian ones are still enforceable. Age does often weaken the practical enforcement picture (defunct beneficiaries, changed estate character), which is what indemnity insurers price. But "old" never automatically means "gone"; check the register.
The developer wants a fee just to look at my application. Is that normal?
Yes — administration fees of £50–£500 are standard and, annoyingly, payable whether or not consent is granted. Treat it as a project cost like building control fees. What's not standard is an open-ended or percentage-based demand; take advice before agreeing to anything beyond a fixed admin fee.
Do covenants affect what the conversion costs?
Only at the edges: the consent fee, occasionally a requirement to upgrade the driveway, and a few weeks of lead time — run in parallel with drawings and building control, it rarely delays the start. The 2026 cost guide includes it as a line item in the worked examples.
I'm buying a house on Kingsbrook and want to convert the garage later. What should I do now?
Ask your conveyancer two questions before exchange: does the title carry garage-use or alteration covenants, and did the plot's planning consent remove permitted development rights or condition the garage as parking? Ten minutes of your solicitor's time now beats discovering either answer after completion.
