If you’re pricing up autism support in London, here are the figures you need first. A private autism assessment for a child typically costs £1,500 to £3,500, with London clinics often sitting at the upper end of that range because of higher clinician fees and demand. Private ABA therapy costs in London run at roughly £50 to £60 an hour for direct sessions, and a full‑time programme commonly totals £3,000 to £5,000 a month, or considerably more once supervision and reporting are added.
Your immediate next steps matter more than the exact figures. Check your local NHS autism assessment waiting time now, because it affects whether private diagnosis is worth paying for. Ask your local authority about an Education, Health and Care Plan (EHCP) if your child is school-age, since this is the route most likely to secure funded provision long-term. And when you contact a private provider, ask directly whether they use ADOS‑2 and ADI‑R, the two internationally recognised diagnostic tools, and whether they are registered with the Care Quality Commission (CQC).
Quick reality check: one detailed economic analysis found that early intensive ABA‑based interventions are unlikely to represent value for money against NICE cost thresholds, given current evidence and typical programme costs, though the researchers stress this comes with real uncertainty. That doesn’t mean ABA isn’t right for your child. It means the financial case for full intensity, private‑only programmes deserves scrutiny before you commit a family budget to it.
ABA pricing rarely appears as one clean number, and that’s precisely what catches families out. A quoted “hourly rate” usually covers direct one‑to‑one therapy only. Layered on top of that are supervision fees from a senior clinician or a BCBA/UK‑SBA‑credentialled supervisor, programme design time, materials, therapist travel, and monthly reporting or admin. Skip any of these and your budget will be wrong within weeks.
Here’s how the components typically break down for a London‑based programme:
Nationally, private ABA is often quoted at £30 to £60 per hour, with London providers generally sitting at the top of that band. A part‑time programme of 10 to 15 hours a week might land between £2,000 and £4,000 a month once supervision is included; a full‑time, intensive programme of 25 to 35 hours a week can realistically hit £4,000 to £6,000 a month, or £25,000 to £50,000 annually.
London’s premium isn’t arbitrary. Three things push the price up: therapist supply is tighter relative to demand than in most other UK regions, the cost of living pushes up what agencies must pay qualified staff, and families in London are more likely to request in‑home delivery rather than clinic‑based sessions, which adds travel time to every invoice. A senior, credentialed supervisor overseeing junior therapists also costs more than a less experienced team delivering the same hours.
Budget for these recurring extras beyond the headline hourly rate:
Pro Tip: Ask providers about hybrid delivery, where a senior therapist supervises remotely and a junior therapist delivers most direct hours. It’s usually cheaper than an all‑senior team, and combining it with parent training to handle some sessions yourself can meaningfully cut the weekly hours you need to buy in.
A gold‑standard multidisciplinary assessment isn’t a single appointment. It’s a package of clinician time that, when itemised honestly, explains why the fee looks the way it does. A typical assessment includes an initial triage call, an ADOS‑2 observation session with your child, an ADI‑R structured interview with parents or carers, a review of school and health records, input from more than one clinician, and a written report.
For London families, realistic price points look like this:
The timeline from first enquiry to final report typically runs 6 to 12 weeks with a private provider, against considerably longer NHS waits. Session time itself might only total 3 to 4 hours across ADOS‑2 and ADI‑R, but report writing regularly adds another 6 to 10 hours of clinician time, which is where a large share of the fee actually goes.
Before booking, check each provider against this shortlist:
Report acceptance matters more than speed. Insiders in the sector note that reports omitting clear detail on ADOS‑2 and ADI‑R use, or clinician credentials, are less likely to be accepted as evidence by local authorities. Paying slightly more for a properly documented MDT report can save you months of dispute later.
NHS pathways in London vary by borough and integrated care board, but the general picture is consistent: NHS trusts assess for diagnosis, and some offer Positive Behaviour Support (PBS) or general behavioural guidance, yet full ABA programmes are rarely funded directly by the NHS in the way private providers deliver them. Where NHS support exists, it tends to be lighter touch than a private, intensive ABA programme, focused on strategies parents and schools can apply rather than dedicated one‑to‑one hours.
Waiting times are the other half of the equation, and London is no exception to the national pattern of long queues. Waits vary significantly between boroughs and NHS trusts, and it isn’t unusual for families to wait well over a year from referral to diagnostic appointment on some pathways. That gap is exactly why many London parents look at private assessment in the first place: not because they’ve given up on the NHS, but because a diagnosis unlocks school support and EHCP applications sooner.
Whether a local authority accepts your private diagnosis depends heavily on how thorough it is. A gold‑standard MDT report increases the likelihood of acceptance for statutory assessment purposes, but local authorities aren’t obliged to accept every private report at face value, and practice does vary. If a report is refused or challenged, that’s precisely the point at which specialist legal advice from a charity such as IPSEA becomes worthwhile.
Pro Tip: When submitting a private report to your local authority for EHCP purposes, attach a short covering letter listing exactly which tools were used, the assessing clinicians’ qualifications, and how the findings map to your child’s day-to-day needs at school. Local authorities process dozens of these reports; making the evidence easy to locate speeds up their review considerably.
An EHCP is the single most powerful funding lever available to London families, because once provision is named in Section F of the plan, the local authority becomes legally obliged to fund it. That’s a very different position from asking a council to consider funding informally. Section E sets out your child’s outcomes, and Section J covers personal budgets, which is where things get practically useful for parents managing ABA or therapy costs directly.
Personal Budgets and Direct Payments let you take funding the local authority would otherwise spend on provision and use it to buy services yourself, including private therapy hours or support staff. Local authorities must publish Local Offer information explaining eligibility and the conditions attached to direct payments, so that page is worth reading before you apply. One important limit to know: the Dedicated Schools Grant cannot be used to fund a local authority’s own SEND administration or assessment costs, which is a common source of confusion when families ask why councils won’t cover certain fees directly.
Beyond the EHCP route, several other sources can help with cost:
The practical sequence most London families follow looks like this:
Useful first stops: gov.uk’s SEND guidance for the EHCP process itself, your local authority’s Local Offer page for personal budget rules, IPSEA for legal advice on disputes, and the National Autistic Society for practical, day‑to‑day guidance. Keep copies of every school report, assessment, and letter you’ve ever received before you start any application. You’ll be asked for them more than once.
Numbers land differently once they’re attached to a real household, so here are three common scenarios London parents actually face.
Pro Tip: When money is tight, prioritise spending in this order: assessment first, because nothing else works without a diagnosis; supervision second, because unsupervised direct hours waste money on inconsistent technique; then direct therapy hours last, scaled to whatever’s left in the budget. A simple monthly template of (hourly rate × weekly hours × 4.3) + supervision + admin gets you within a reasonable estimate of your real monthly cost.
Credentials matter more in this sector than almost any other type of home‑based support, because a poorly evidenced report can cost you months of delay down the line. Before signing with anyone, verify:
When you speak to a provider, ask these questions directly and note how confidently they answer:
Watch for these warning signs. Vague or generic reporting that doesn’t reference specific tools or observations is one. Reluctance to disclose the lead clinician’s actual qualification is another. So is a remote‑only assessment marketed as equivalent to a full in‑person MDT process, or any pressure to sign a long‑term contract before you’ve seen a sample of their work.
Transparent, itemised quotes showing assessment time, report writing, supervision, and travel separately are a strong signal of a well‑run provider. If a quote arrives as a single lump figure with no breakdown, ask for the itemised version before you commit.
Numbers on a page rarely capture how families actually spend, and the pattern London agencies see day to day tends to be more pragmatic than the headline programme costs suggest. Rather than committing to a full private ABA programme outright, many parents run a partial private arrangement, perhaps 8 to 15 hours a week, while an EHCP application works through the system in parallel. That approach reduces short‑term outlay while building evidence that supports the eventual local authority funding case.
A typical timeline looks something like this: assessment first (private or NHS, whichever is faster), then a period of light private support alongside the EHCP application, followed by a shift toward EHCP‑named provision once the plan is finalised, usually somewhere between six months and a year after the initial diagnosis.
What doesn’t show up in national cost surveys is how much everyday domiciliary support matters alongside clinical therapy. Respite visits, short‑term staffing to cover a parent’s work commitments, or simply a DBS-checked carer who understands the household’s routine, can be the difference between a sustainable arrangement and a family running on empty by month three of an intensive programme.
Families rarely need just one type of support. A parent managing ABA sessions, school liaison, and an EHCP application at the same time is running three separate part‑time jobs on top of everything else. Practical home support, delivered by qualified, DBS‑checked staff, is often what makes the clinical side actually sustainable rather than something that collapses under its own weight after a few months.
CQC regulation isn’t a box‑ticking formality in this context. It’s the difference between a provider whose standards are independently checked and one operating entirely on its own word.
Clinical intensity gets most of the attention in autism budgeting conversations, and understandably so. But the families who cope best over the long run aren’t always the ones spending the most on direct therapy hours. They’re the ones who’ve built a support structure around the therapy: someone reliable to help with school runs during appointment weeks, respite when a parent is genuinely at breaking point, and staff who know the household well enough not to need re‑briefing every visit.
Kells-care has spent over thirty years providing home care across London, and we’re CQC regulated with fully DBS‑checked, qualified carers. That doesn’t make us a substitute for ADOS‑2 assessments or ABA supervision. It makes us the practical layer underneath those things: the part of a family’s plan that keeps everyone functioning while the clinical and legal processes run their course.
If your budget is limited, here’s the order I’d suggest. Get the assessment first, because everything else depends on having a diagnosis. Apply for the EHCP early, even if you’re also paying privately in the meantime, because the process takes months regardless of when you start. And don’t underestimate ordinary home support as a lower‑cost way to protect your own capacity to manage everything else. It’s often the cheapest, most immediately available piece of the puzzle, and the one families regret not arranging sooner.
Kells-care isn’t a clinical provider, and we won’t pretend to replace an ADOS‑2 assessment or an ABA supervisor. What we do offer is the practical layer that makes those services sustainable: flexible home visits, respite care, live‑in support, and short‑term staffing that fit around a family’s clinical schedule rather than competing with it. If you’re juggling therapy sessions, school meetings, and an EHCP application, a few hours of dependable domiciliary support each week can be the difference between coping and burning out.
Our home care services are built around what your household actually needs, whether that’s a regular check-in visit, cover during a therapy‑heavy week, or a live-in carer while you focus on appointments. Every carer is DBS‑checked, qualified, and working under our CQC registration, so you’re not adding another unvetted variable to an already complicated plan.

| Full‑programme monthly cost | Full‑time ABA in London commonly totals £3,000 to £5,000 or more per month. |
| EHCP is the key funding lever | Provision named in Section F obliges local authority funding; apply early even while paying privately. |
| Report quality determines acceptance | Insist on ADOS‑2, ADI‑R, and named clinician credentials so reports hold up for EHCP or tribunal use. |
| Home support eases the burden | Kells-care’s CQC‑regulated, DBS‑checked carers provide respite and flexible visits alongside clinical therapy. |
Before you contact a provider or submit an EHCP application, a handful of official and charity pages are worth bookmarking. Start with gov.uk’s SEND and high needs funding guidance for the legal framework behind EHCPs and personal budgets. Add the National Autistic Society for practical, plain-English advice on access routes and support. IPSEA remains the go‑to for legal advice if a local authority refuses to accept a private diagnosis or disputes an EHCP decision. Your local council’s Local Offer page will confirm exactly how personal budgets work in your specific borough, since practice does vary across London.
